Negative effects of an autogenic ecosystem engineer: interactions
... ABSTRACT: Organisms that physically modify habitat by their own presence can either positively or negatively affect other species. The direction of the effect depends on how physical variables are modified and the response of species to these variables. In this study, we investigated the interaction ...

It is probably safe to say that if they are hungry and deprived of preferred vegetation, they will consume any plant material they can find, including terrestrial plants overhanging the water. Young grass carp (less than 3 pounds) ...

In this article, we suggest that evaluating the role of artificial reefs will benefit markedly from, first, more detailed comparisons of the populations and assemblages ...

CMN Microhabitat Fact Sheet - Far South Coast Conservation

Areas of native vegetation provide habitat for many species of fauna, but simply having trees, grass and shrubs doesn’t necessarily mean all fauna is catered for. Microhabitat refers to features that account for faun ...

Artificial turf
Artificial turf is a surface of synthetic fibers made to look like natural grass. It is most often used in arenas for sports that were originally or are normally played on grass. However, it is now being used on residential lawns and commercial applications as well. The main reason is maintenance—artificial turf stands up to heavy use, such as in sports, and requires no irrigation or trimming. Domed, covered, and partially covered stadiums may require artificial turf because of the difficulty of getting grass enough sunlight to stay healthy. But artificial turf does have its downside: limited life, periodic cleaning requirements, petroleum use, toxic chemicals from infill, and heightened health and safety concerns.Artificial turf first gained substantial attention in the 1960s, when it was used in the newly constructed Astrodome. The specific product used was developed by Monsanto and called AstroTurf; this term since then became a colloquialism for any artificial turf throughout the late 20th century. AstroTurf remains a registered trademark, but is no longer owned by Monsanto. The first generation turf systems (i.e., short-pile fibers without infill) of the 1960s have been largely replaced by the second generation and third generation turf systems. Second generation synthetic turf systems feature longer fibers and sand infills, and third generation systems, which are most widely used today, offer infills that are mixtures of sand and granules of recycled rubber.
