... The Impact of moisture on terrestrial animals: • Most mammals can withstand a loss of about 10% of their body water • Frogs can use as much as 40% of their body water • Water is replenished by drinking from free water such as lakes, streams, springs, and dew on leaves • Water can be replenished via ...

The effects of artificial illumination on invertebrate drift
... Freshwaters cover only about 0,8% of the total surface of the globe. However, 9.5% (126,000 species) of all species on earth are freshwater organisms (Dudgeon et al., 2006;Balian et al., 2008). This means that of the world’s total biodiversity, much of it lives in freshwater. These organisms could p ...

Recruitment of marine invertebrates - University of California, Santa

Non-random patterns of recruitment, such as differences in the density of recruitment with height on the shore (Underwood 1979) or differences in the density of recruitment with patch size (Jackson 1977; Keough 1982a), or with microh ...

Partitioning of soil water among tree species in a Brazilian Cerrado

Models explaining the structure of savanna ecosystems typically involve water and nutrients as limiting resources, and a two-layered (grasses versus woody species) soil--water system (Walker and Noy-Meir 1982, Knoop and Walker 1985). According to this model, the shallow roots of grasses make them su ...

Regime Shifts in the Anthropocene: drivers, risk

Kelp is a three dimensional structure that offers shelter and food for many species; urchin barrens and turfs do not have this characteristic. This loss is associat ...
