A interação co-evolutiva entre insetos e plantas como estratégia ao manejo agroecológico em
agroecossistemas sustentáveis.
Provedor de dados: 119
Autores: LOVATTO, P. B.; SCHIEDECK, G.; GARCIA, F. R. M.
Diante da crise socioambiental e econômica aliada à agricultura convencional, torna-se urgente o desenvolvimento de técnicas que
contribuam para a transição produtiva do modelo atual para formas de produção mais sustentáveis. Deste modo, o conhecimento
sobre a interação inseto-planta revela-se como uma importante ferramenta para elaboração de mecanismos de manejo a serem
aplicados aos sistemas produtivos que privilegiem a produção orgânica. Assim, o presente trabalho faz uma revisão sobre a defesa
das plantas e a sua relação com a herbivoria de insetos, direcionando, a partir das inter-relações co-evolutivas destes organismos,
estratégias possíveis de utilização para o manejo de insetos considerados ?pragas? agrícolas em agroecossistemas.

SGRENZAROLI, M.; FRITZ, S.
A digital land cover map of South America has been produced using remotely sensed satellite data acquired between 1995 and the
year 2000. The mapping scale is defined by the 1 km spatial resolution of the map grid-cell. In order to realize the product,
different sources of satellite data were used, each source providing either a particular parameter of land cover characteristic
required by the legend, or mapping a particular land cover class. The map legend is designed both to fit requirements for regional
climate modelling and for studies on land cover change. The legend is also compatible with a wider, global, land cover mapping
exercise, which seeks to characterize the world?s land surface for the year 2000. As a first step, the humid forest domain has...

Linking bayesian belief networks and GIS to assess the ecosystem integrity in the brazilian Amazon.

Autores: VERWEIJ, P.; SIMOES, M.; ALVES, A.; FERRAZ, R.; CORMONT, A.
Deforestation and climate change heavily impact the ecosystem of the Amazon rainforest threatening its resilience and the
sustainability of many human activities. Land protection may prevent ecosystems and their services to deteriorate from the
pressures of agricultural expansion, population growth and wood harvesting. In the Brazilian Amazon land protection occurs in
several forms such as environmental conservation, setting biodiversity priority areas and the delineation of indigenous lands. Still,
the effects are not clear as understanding of the ecosystems is incomplete and responses to human actions are highly uncertain.
Bayesian Belief Networks (BBN) are models that probabilistically represent correlative and causal relationships among variables.

Agricultural research and development plays an essential role in a nation's economic development, providing for food security for
an ever-increasing population. In developed countries, the gap between potential and actual yield is largely closed because of a
combination of advanced technologies, high-yielding new varieties and the application of agrochemicals in highly mechanized
production systems. In most of these countries, agricultural production exceeds national demand, resulting in excess products for
export. In many of the developing countries, however, agricultural productivity is still far below what it should be because of
multiple technical and socio-economic constraints. Food deficits are the norm in poor and middle-income countries, requiring...

Ecosystem regime shifts, which are long-term system reorganizations, have profound implications for sustainability. There is a
great need for indicators of regime shifts, particularly methods that are applicable to data from real systems. We have developed a
form of Fisher information that measures dynamic order in complex systems. Here we propose the use of Fisher information as a
means of: (1) detecting dynamic regime shifts in ecosystems, and (2) assessing the quality of the shift in terms of intensity and
pervasiveness. Intensity is reflected by the degree of change in dynamic order, as determined by Fisher information, and
pervasiveness is a reflection of how many observable variables are affected by the change. We present a new robust methodology

Ecosystem services are necessary, yet not sufficient for human well-being (however defined). Insufficient access to the ecosystem
provisioning service of food is a particularly important factor in the loss of human well-being, but all ecosystem services
contribute in some way to well-being. Although perhaps long obvious to ecologists, the links between ecosystems and aspects of
human well-being, including health, have been less well understood among the social science community. This situation may now
be starting to change, thanks in part to the Millennium Ecosystem Assessment (MA). Causality between ecosystem services and
well-being is bidirectional; it is increasingly clear that functioning societies can protect or enhance ecosystem services, and...

Research on the barriers and limits to climate change adaptation identifies many factors, but describes few processes whereby
adaptation is constrained or may indeed fail to avoid catastrophic losses. It often assumes that barriers are by and large distinct
from limits to adaptation. We respond to recent calls for comparative studies that are able to further knowledge about the
underlying drivers of barriers and limits to adaptation. We compare six cases from across Australia, including those in alpine
areas, rivers, reefs, wetlands, small inland communities, and islands, with the aim of identifying common underlying drivers of
barriers and limits to adaptation. We find that the path-dependent nature of the institutions that govern natural resources and...

Understanding Complex Human Ecosystems: The Case of Ecotourism on Bonaire
Provedor de dados: 7
Autores: Abel, Thomas; National Taipei University; [email protected].
It is suggested that ecotourism development on the island of Bonaire can be productively understood as a perturbation of a
complex human ecosystem. Inputs associated with ecotourism have fueled transformations of the island ecology and sociocultural
system. The results of this study indicate that Bonaire's social and economic hierarchy is approaching a new, stable systems state
following a 50-yr transition begun by government and industry that stabilized with the appearance of ecotourism development and
population growth. Ecotourism can be understood to have "filled in" the middle of the production hierarchy of Bonaire.
Interpreted from this perspective, population growth has completed the transformation by expanding into production niches at
smaller...

Lagoons are highly productive coastal features that provide a range of natural services that society values. Their setting within the
coastal landscape leaves them especially vulnerable to profound physical, ecological, and associated societal disturbance from
global climate change. Expected shifts in physical and ecological characteristics range from changes in flushing regime,
freshwater inputs, and water chemistry to complete inundation and loss and the concomitant loss of natural and human
communities. Therefore, managing coastal lagoons in the context of global climate change is critical. Although management
approaches will vary depending on local conditions and cultural norms, all management scenarios will need to be nimble and to

Institutions are the mechanisms that integrate the human and ecological spheres. This paper discusses the institutional challenge of
integrating salmon (Oncorhynchus spp.) ecosystems and human systems in ways that effectively promote resilience. Salmon
recovery in the Columbia River Basin demonstrates the challenge. Despite the comprehensive scope of Basin salmon
management, it has a number of problems that illustrate the difficulties of designing institutions for ecosystem and human system
resilience. The critical elements of salmon ecosystem management are incentives and transaction costs, and these comprise a large
piece of missing institutional infrastructure. Once the focus is placed on incentives and costs, a number of different management
strategies...

Evaluation of the carrying capacity of molluscan shellfish ecosystems
Provedor de dados: 5
Autores: Heral, Maurice.
Growth of molluscs raised in coastal zones, where the water exchange rate is low, appears to be limited, once a certain biomass
level is attained, by the availability of food, making it necessary to determine as accurately as possible the trophic capacity of an
ecosystem. This paper analyses the various sources of food for molluscs. It would appear that dissolved organic substances play a
major role, providing up to half the energy necessary for their metabolism. Particulate material is filtered by molluscs in
proportion to their size, with optimum filtration rates varying with species. The negative effect on meat production of high
mineraI seston rates is demonstrated, and an analysis provided of the respective role of each component of organic matter....

The Millenium Ecosystem Assessment (2005) demonstrated that the biodiversity is the keystone for the sustainaibility of present
and future ecosystems services. In spite of the highly significant effort carried out by the Census of Marine Life over the last ten
years, and an increasing research effort, marine biodiversity and precise ecosystem functioning remain largely unknown and
failure to reach the CBD 2010 objectives is obvious. Meanwhile, the concept of ‘ecosystem approach’ is progressing, translated
into new policies such as the revised European Common Fisheries Policy (CFP). We might question if the scientific community is
ready enough to built scenarios for the future and provide integrated advice to the policy makers for biodiversity conservation...

With the advent of deep submergence research vessels (DSRVs) biological and ecological studies of ocean deeps have made great
strides. Especially these submersibles allowed to conduct physiological and biochemical experiments on benthic fauna directly on
the bottom or on board with alive retrieved animals. A second great interest is the possibility to work in chaotic areas and on
microenvironments. Without DSRVs most of measurements and observations obtained on hydrothermals vents would had been
impossible. We will present the different equipment designed for the two French DSRVs used during the cruises conducted by the
Departement "Environnement Profond" de l'IFREMER to study hydrothermal and "normal" deep-sea ecosystems. We will discuss

The ICES Study Group on the North Sea Benthos Project 2000 undertook to integrate recent (1999–2002) macrobenthic infaunal
and environmental data from various national sources. The main aim was to compare the outcome with that of the ICES North Sea
Benthos Survey conducted in 1986, to identify any significant changes and their likely causes. In the process, the exercise yielded
valuable lessons for the conduct of international collaborative programmes, as well as insights into the utility of a range of
interpretational tools. These are timely in view of increasing requirements for periodic sea-wide assessments of quality status to
meet international obligations, such as those under OSPAR, ICES, HELCOM, and EU auspices for European waters. This paper...

Models of relations between bacteria and plankton, and regeneration processes in marine planktonic
ecosystem.
Provedor de dados: 5
Autores: Martin, Y; Lelong, P; Cauchi, B.
In order to study bacteria-plankton relationships, experimental and mathematical models were used to stimulate biological
processes implicated in plankton ecosystems and to analyze community relationships. The model components are phytoplankton,
zooplankton, autotrophic and heterotrophic bacteria, ciliates, nutrients, organic matter and phytoplankton antibiotics. This study
shows the importance of some factors affecting bacteria communities dynamics and the bacterial activity in mineralization
process. Bacterial populations seem to be controlled essentially by the concentration and chemical composition of organic
substrates. Antibiosis and predation show a lesser importance on changes in bacteria communities.

The Momareto cruise was held from August 6 to September 6, 2006 on the new French oceanographic vessel Pourquoi pas? The
ROV Victor 6000 visited three vent fields, ranging from 850m to 2300m, on the Mid-Atlantic Ridge. The scientific objective of
the cruise was to study the spatial and temporal dynamics of hydrothermal communities colonizing these active vent sites. Aside
scientific and technological objectives, one of the major goals of this cruise was to share the excitement of our science with the
public. For this, the results of the project were shared through different media. The most challenging and exciting communication
event remains the real-time transmission of images acquired by the ROV Victor at 1700m depth to a 250 person audience on land.

The problems of application of radiocarbon method for estimation of primary production in
oligotrophic waters
Provedor de dados: 5
Autores: Krupatkina, D; Berland, B; Maestrini, S.
The errors in primary production estimation by the radiocarbon method may differ from one trophic region to another. Such
supposition is based on unequal phytoplanktonic structural characteristics of these regions. These errors are likely to appear rather
significant in oligotrophic waters predominated by nano- and ultranano-plankton (the so-called picoplankton). The organic
substance of oligotrophic waters is obviously produced by picoplankton for the most part, the need for clarifying possible errors
when estimating primary production by the radiocarbon method, which is the purpose of the present work is urgent. For these
topics in oligotrophic waters, measurements were carried out in two ways: (1) according to the generally accepted pattern

Sensitivity of marine systems to climate and fishing: Concepts, issues and management responses
Provedor de dados: 5
Autores: Perry, R. Ian; Cury, Philippe; Brander, Keith; Jennings, Simon; Moellmann, Christian; Planque, Benjamin.
Modern fisheries research and management must understand and take account of the interactions between climate and fishing,
rather than try to disentangle their effects and address each separately. These interactions are significant drivers of change in
exploited marine systems and have ramifications for ecosystems and those who depend on the services they provide. We discuss
how fishing and climate forcing interact on individual fish, marine populations, marine communities, and ecosystems to bring
these levels into states that are more sensitive to (i.e. more strongly related with) climate forcing. Fishing is unlikely to alter the
sensitivities of individual finfish and invertebrates to climate forcing. It will remove individuals with specific...

Do explicit criteria help in selecting indicators for ecosystem-based fisheries management?
Provedor de dados: 5
Autores: Rochet, Marie-joelle; Rice, Jake.
An evaluation framework developed to help select an appropriate suite of indicators to support an ecosystem approach to fisheries
management was tested experimentally by asking independent experts to weight the selection criteria provided and to score
indicators against those criteria in several ecological settings. The steps in selecting indicators proved to be prone to subjectivity
and value judgement, and differences in scores between experts were the main factor contributing to variability in evaluation
results. Having to justify scores in a written document did not improve consistency among the experts. The framework, however,
did enhance transparency by explicitly stating each issue to be addressed in the selection process, and by giving experts or...

Utilisation du submersible Cyana pour l'etude du macroplancton fragile
Provedor de dados: 5
Autores: Laval, P.
The gelatinous macroplanktonic organisms living in the deep sea can only be studied with manned submersibles. There is
presently in increasing interest in the study of the role of this part of the pelagic ecosystem, because they are strongly involved in
the transformation of the particulate organic matter. Their transparency, small size and mobility present technical challenges,
unanticipated by the designers of the first submersibles, aimed at the sea bottom observation. Despite these limitations, the use of
conventional submersibles has brought very interesting results. It is hoped that engineers will take into account the requirements
of pelagic observations in the design of future submersibles.

Mangrove forests are unique ecosystems which provide a range of important goods and services. However, they are suffering high
rates of destruction around the world, and will be one of the first ecosystems affected by the predicted sea level rise. This project
aims to establish re-planted experimental plots of mangroves in cleared areas. Experimental treatments will consist of plots of
three different tree species, along with all possible multi-species mixtures and unplanted controls. Volunteers will assist in
planting mangroves, and in measuring a range of biological and physical parameters relevant to important ecosystem functions,
such as productivity and growth rates, susceptibility to disease, faunal abundance (of fish and crabs) and sedimentary...

Ecosystem structure and dynamics of the marine system of Sierra Leone for three time periods: 1964,

Provedor de dados: 20
Autores: Heymans, S.J.; Vakily, J.M.
We present the key feature of a quantitative food web model for the shelf and slope waters off Sierra Leone, constructed using the
Ecopath with Ecosim software. Three periods are represented: 1964, based on data from the Guinean Trawling Survey,
complemented with field data on lower trophic levels gathered in the late 1950/early 1960s and published by A.R. Longhurst;
1978, for which fish abundance data from an ex-USSR survey exist, along with related, scattered fisheries information; and 1990,
for which a fair amount of fisheries data exist, along with the results of a Spanish trawl survey. Demersal fish biomass appears to
have declined linearly from 1964 to 1990, due to the massive increase of the catches of distant water fleets operating in Sierra
Leone,...

Diversity and stability of demersal species assemblages in the Gulf of Guinea
Provedor de dados: 20
Autores: Koranteng, K.A.
The structure of demersal fish assemblages on the continental shelf and upper continental slope of the Gulf of Guinea is described.
Community structure is determined primarily by depth and type of sediment on the seabed. Changes in the composition of the
identified species assemblages over a 25-year period are examined.
The dynamics of the assemblages are influenced by
physico-chemical parameters of the water masses, mainly temperature, salinity and dissolved oxygen, which are periodically
modified by the seasonal coastal upwelling that occurs in the western Gulf of Guinea. Increased irresponsible fishing operations
(like the use of explosives) that lead to habitat alteration and other anthropogenic activities like oil and gas exploration which have

El análisis de largo plazo de las pesquerías costeras de Uruguay sugiere que el estado de los principales recursos es preocupante.
Esto puede deberse a múltiples causas (sobrepesca, polución, causas naturales), a lo cual se suman fallas en el diseño (e.g.
información de base insuficiente) o en la implementación de las normativas vigentes (e.g. fiscalización), así como a la ausencia de
un enfoque integrado. Este libro plantea estrategias para el desarrollo e implementación del Manejo Ecosistémico de Pesquerías

Mangrove ecosystems on the coast of Cameroon are valuable both for their contributions to local livelihoods and the globally
important biodiversity that they contain. However, these areas are threatened by a number of development pressures as well as
unsustainable management and harvesting practices of the local communities living there. This project aims to strengthen
protection and reduce degradation in these areas by supporting inter-sectoral co-ordination and collaboration (within an agreed

their livelihoods as well as assist with the conservation of globally important biodiversity found in these areas. At the national

Sediment characteristics and tidal currents were studied in the 1500 ha intertidal area south of Inhaca Island, Mozambique.
Thetide is semi-diurnal with a range at spring of about 3 m. The area connects directly to the ocean through the Ponta Torres

measured in the Ponta Tones strait. After Low Water, Indian ocean water starts entering the tidal flats, while entrance from the
MaputoBay side is delayed by one to several hours. With only one tide gauge and one current meter at hand, we found indications
of ahigher mean sea level on the oceanic side (probably due to ocean wave set up) and a mean flow in the Ponta Torres

A Comparison Of Condition Factor And Gonadosomatic Index Of Sardine Sardinops Sagax Stocks In
The Northern And Southern Benguela Upwelling Ecosystems, 1984–1999
Provedor de dados: 20
Autores: Van der Lingen, C.D.; Kreiner, A.; Fréon, P.
Time-series of condition factor (CF) and gonadosomatic index (GSI) were generated using general linear models (GLM) for
sardine Sardinops sagax stocks in the northern and southern Benguela ecosystems over the period 1984–1999. During this period
the biomass of sardine in the northern Benguela remained at relatively low levels of <500 000 tons, whereas that of southern
Benguela sardine increased 40-fold to 1.3 million tons. The GLMs explained 27 and 45% of the observed variation in CF, and 32
and 28% of the observed variation in GSI, for sardine in the northern and southern Benguela subsystems respectively. Whereas
the sardine CF in the northern Benguela remained stable over time, that for the southern Benguela stock declined steadily during
the study...

Management of Oil Spill Dispersal Along the Nigerian Coastal Areas
Provedor de dados: 20
Autores: Nwilo, P.C.; Badejo, O.T.
Nigeria, one of the world’s largest oil exporters, has a coastline of approximately 853km facing the Atlantic Ocean. This coastline
lies between latitude 4o 10’ to 6o 20’ N and longitude 2o 45’ to 8o 35’ E. The Nigerian coast is composed of four distinct
geomorphology units namely the Barrier-Lagoon Complex; the Mud Coast; the Arcuate Niger Delta and the Strand Coast. 90-95%
of export revenues in Nigeria is from the oil sector. Nigeria’s oil reserves are about 31.5 billion barrels, while Nigeria’s crude oil
production averaged 2.118 million barrels per day in 2002. Oil spillage is a major environmental problem in Nigeria. Between
1976 and 1996 Nigeria recorded a total of 4835 oil spill incidents, which resulted in a loss of 1,896,960 barrels of oil to the...

Towards the development of environmental indices for the Namibian shelf, with particular reference
to fisheries management.
Provedor de dados: 20
Autores: Bartholomae, Ch.; Van der Plas, A.
The Namibian Ministry of Fisheries and Marine Resources has the task of collecting and providing relevant oceanographic
information for management of their fisheries. However, quality information is difficult to provide because of the complexity of
the processes involved in the Namibian marine ecosystem. Nonetheless, there are oceanographic data available that can contribute
to fisheries management by improving the general understanding of important oceanographic processes related to fisheries. The
focus of this paper is on the development of simple environmental indices that can serve as a measurement or proxy of the state or
intensity of certain important oceanographic processes or variables for temporal comparison. These indices relate to
oceanographic...

The Benguela Current ecosystem is situated along the coast of south western Africa, stretching from east of the Cape of Good
Hope, in the south, northwards into Angola waters and encompassing the full extent of Namibia’s marine environment. It is one of
the four major coastal upwelling ecosystems of the world which lie at the eastern boundaries of the oceans. Like the Humboldt,
California and Canary systems, the Benguela is an important centre of marine biodiversity and marine food production. Its
distinctive bathymetry, hydrography, chemistry and trophodynamics combine to make it one of the most productive ocean areas in
the world, with a mean annual primary productivity of 1.25 kilograms of carbon per square metre per year—about six times higher

Coastal Ecosystems
Provedor de dados: 20
The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and
comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense
or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands
include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was
originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high
tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the

Il est connu que les ports soumis à un trafic maritime intense réceptionnent éventuellement les eaux de ballast des navires en
provenance de diverses contrées océaniques. De part le monde, le transfert et l’invasion de plusieurs espèces nuisibles via le
déversement des eaux de ballast et le fouling des coques des navires ont été amplement mis en cause ces derniers temps. Ces
introductions peuvent causer de nombreux dégâts aux secteurs avoisinants et notamment dans les zones de production des
coquillages surtout si les espèces introduites sont constituées de phytoplancton toxique. Au terme de 4 années de suivi de la

Le suivi régulier des teneurs en chlorophylle a et en sels nutritifs dans la lagune de l'Ichkeul durant l’année 1993 a permis de
mieux comprendre le fonctionnement de cet écosystème, milieu original et complexe. Les cycles annuels de la chlorophylle et des
sels nutritifs montrent des fluctuations importantes, à l'échelle hebdomadaire. Les fortes biomasses phytoplanctoniques sont
observées en hiver en période de courant sortant, en opposition avec les concentrations de phosphore réactif dissous qui ne sont
notables que dans l’oued Tinja par courant entrant. Les nitrates et nitrites sont en concentrations plus irrégulières, sans saisonnalité
marquée. La gamme des concentrations mesurées en 1993 a été comparable à celle observée lors des années précédentes.

Autores: Ndirangu, S.; Uku, J.; Muthama, C.
In May 1999, two sites were selected within the Mombasa Marine Park and Reserve for the study of macroalgal succession due to
bleaching. One of the sites was Starfish, which lies within the Mombasa Marine Park and is protected from fishing and the other
site was Ras Iwatine, which lies in the Reserve area and is Subjected to fishing activities. The study revealed that the Starfish site
had a significantly higher hard coral cover, which did not change over the study period. A comparison of the density of
macroalgae revealed that a higher proportion of the substrate in Ras Iwatine was dominated by macroalgae. Settlement tiles, used
to study algal recruitment, indicated that the succession process in the Starfish site passes through more stages compared to...

Use of environmental parameters to explain the variability in spawnerrecruitment
Provedor de dados: 20
Autores: Kirchner, C. H.; Bartholomae, C. H.; Kreiner, A.
This study attempts to explain the variability in recruitment of sardine in the northern Benguela and to develop potential models
by including environmental information to predict recruitment. Two different recruitment and spawner number datasets were
available: a VPA-developed dataset, for the period 1952–1987, and data from a simple age-structured model for 1992–2007. In
all, four environmental indices were used: the degree of the intrusion of the warm Angola Current into northern Namibia, termed
the Angola–Benguela front index; the extent of the upwelling area off central Namibia; average sea surface temperature (SST)
over the northern and central Namibian shelf; and wind stress anomalies at Lüderitz as an indicator of upwelling strength.

salinidad, la cual varió entre 75 y 341 °/oo; su incremento y la disminución del nivel de agua, al parecer generaron aumento de la
temperatura y disminución del oxígeno disuelto, con rangos de 26,3 y 41 °C para la primera y O y 5,4 mg/l para el segundo.
Aunque en promedio el pH fue neutro (7,5), este sistema reductor, caracterizado además por abundante materia orgánica, generó
en ocasiones una ligera acidez (6,7). La producción primaria neta fue negativa en la mayoría de los casos, como resultado de una...

Mangroves of Western and Central Africa

Autores: Emily, C.; Corinna, R.; Mike, S.
There is an international consensus, expressed in the Convention on Biological Diversity, World Summit on Sustainable
Development, and Millennium Ecosystem Assessment, that biodiversity at all levels – genetic, species and ecosystem – have a
critical role in sustaining livelihoods and human development. They underpin and make possible all forms of economic activity.
Damage to components of biodiversity have economic consequences, the impacts of which fall most heavily on the poor. In few
contexts is this as clear as in the case of mangrove ecosystems and their dependent human populations. Mangroves support
livelihoods in providing habitat for food species, timber for dwellings, cooking and heat, and many other subsistence and
commercial activities....

Characterizing and Comparing the Spawning Habitats of Sardine (Sardinops sagax) and Anchovy
(Engraulis encrasicolus) in the Northern Benguela Region
Provedor de dados: 20
Autores: Tjizoo,Mbeurora Beau.
Spawning habitats of sardine and anchovy in eastern boundary current systems are characterized in an attempt to understand the
fluctuations observed in their abundance. The northern Benguela, as an eastern boundary current system, is characterized by
turbulent conditions that seem to govern the variability observed in the abundance of these species. Sardine and anchovy have
developed mechanisms that enable them to maximize productivity. In the northern Benguela, spawning intensity is historically
known to be high in periods and vicinities where turbulence is reduced. However, it is believed that selection of conditions for
spawning by these species may change withfluctuations in abundance of fish.

Transfer of seston to zooplankton in marine ecosystems
Provedor de dados: 27
Autores: Tackx, M.
When considering zooplankton feeding as one of the pathways involved in the transfer of substances in marine ecosystems, it is
important to study the composition and size distribution of the seston: firstly, the elements in which one is interested may be
associated with different types and sizes of particles; secondly, particle size and composition are important factors in relation t o
the feeding process of the zooplankton itself. High speed cinematographic studies have recently revealed that copepods use two
different mechanisms for feeding. Small particles (< 12 pm) are collected by continuous low amplitude movements of the
second maxillae and combing of the appendages. Larger particles are detected and collected individually by means of a specific...

In the Parc National du Banc d'Arguin (P.N.B.A.) in Mauritania, the mangroves of the West-African coast reach their
northernmost distribution and comprise exclusively <i>Avicennia germinans</i>. As a biogeographically marginal,
monospecific mangal in an area where freshwater availability has decreased over the last decades, concern about the survival of
the mangroves has been expressed. As yet, a description was lacking and no data regarding the fitness of <i>A.
germinans</i> in the P.N.B.A. were available. The mangrove and associated vegetation nearby Cape Timiris (southern

Recent research developments in common-pool resource models emphasize the importance of links with ecological systems and
the presence of non-linearities, thresholds and multiple steady states. In a recent paper Kossioris et al. (2008) develop a
methodology for deriving feedback Nash equilibria for non-linear differential games and apply this methodology to a
common-pool resource model of a lake where pollution corresponds to benefits and at the same time affects the ecosystem
services. This paper studies the structure of optimal state- dependent taxes that steer the combined economic-ecological system
towards the trajectory of optimal management, and provides an algorithm for calculating such taxes.

In many places, growing population, in conjunction with efforts to increase food security, is escalating pressure to expand
agriculture within wetlands. The environmental impact of wetland agriculture can have profound social and economic
repercussions for people dependent on ecosystem services other than those provided directly by agriculture. If wetlands are not
used sustainably, the functions which support agriculture, as well as other food security and ecosystem services, are undermined.

Basin water development and rural dynamics in the Krishna Basin have led to a degradation of downstream ecosystems
manifesting itself by salinizing soil and groundwater, increasing pollution, disappearing mangroves and desiccating wetlands.
Reversing this evolution requires the formal recognition of the environment as a water user in its own right and the
implementation of an environmental water provision. This provision should be based on a two-tier allocation system with assured
discharges in the irrigation canals of the delta and to the ocean. This will lead to further commitment of water resources but this is
needed to reconcile the social, economic and environmental objectives of a sustainable development. Other measures facilitating

Many decisions on water allocation in river basins are made on economic grounds. Environmental and social benefits of water
should also be considered in river basin management, and attempts should be made to value them similarly. This is not a
straightforward task and very few studies have directly addressed this issue to date. In this paper, the Menik Ganga (River) in
southern Sri Lanka is used as a case study to attempt and evaluate the costs and benefits of environmental water allocations,
referred to as ‘environmental flows’ (EF). In this study, a broad definition of EF is used: the components of EF evaluated include
