Does history matter? : An experimental assessment of whether dragonfly colonization history affects insect biodiversity within ephemeral ponds 2012 284377 Current interactions among species could have an important role in controlling biodiversity. Some studies however have shown that the particular time a species arrives at a site during the process of community assembly could alter the strength of spe...
Multiple Factors Influence the Strength of Intraguild Interactions 2011 284377 Species engaged in intraguild predation (IGP) not only compete for the same food resources but can also eat each other. In some cases a predator species in a higher trophic position (i.e. a top predator) can eat a predator species with an intermediat...

IS PREDATION BY TURTLES SUFFICIENTLY STRONG TO AFFECT BIODIVERSITY WITHIN FISHLESS PONDS? 2011 284377 Ecologists have long known that predation can have a strong effect on the diversity and abundance of prey in ecological communities. Much evidence on the importance of predation in aquatic systems has stemmed from studies involving manipulations of a...
Local and Regional Aspects of Habitat Quality Jointly Affect the Biodiversity of Ephemeral Ponds 2012 284377 The biodiversity of local communities is likely affected by both local habitat quality and by the quality of the landscape surrounding the locality. In pond environments habitat quality may be affected by the kind of leaf litter present because leaf ...
Predator Out of Place : The Differential Impacts of Native and Non-native Crayfish on Bufo Tadpoles 2011 284377 Predators have been shown to alter important fitness components (larval period mass at metamorphosis and overall survivorship) of larval anurans. Uncommonly studied predators of tadpoles include crayfish. Both native and introduced crayfish occur in ...
