The Everglades is an internationally recognized iconic, wetland threatened by water
extraction, channelization, and anthropogenic nutrient enrichment. It is a large oligotrophic …

Primary production can be controlled through bottom–up (eg, resources) or top–down (eg,
predators) constraints. Two key bottom–up resources in small aquatic systems are light and …

Predators shape prey populations by elimination of individuals (consumptive effects) and by
inducing modifications in prey behaviour, physiology or morphology (NCE—non …

Animal species differ considerably in their response to predation risks. Interspecific
variability in prey behaviour and morphology can alter cascading effects of predators on …

Risk-taking behaviours that are optimal in one context (predators absent) may be suboptimal
in a different context (predators present), suggesting that individuals with 'bold'behaviours …

Balancing trade-offs between avoiding predators and acquiring food enables animals to
maximize fitness. Quantifying their relative contribution to vital rates in nature is challenging …

METHODS We collected P. duryi Wetherby, 1879 (7.67–23.46 mm shell length, n= 89) and
H. cubensis Pfeiffer, 1839 (4.58–9.25 mm shell length, n= 30) from populations maintained …

The predator-permanence hypothesis predicts that as hydroperiod increases in lentic
ecosystems, biotic interactions—mainly predation—replace physical factors like drying as …

In natural populations of insect herbivores, genetic differentiation is likely to occur due to
variation in host plant utilization and selection by the local community of organisms with …

A tracer experiment using isotope 15 N was performed to study the assimilation and
retention of nitrogen from feces by two planktivorous fish, silver carp Hypophthalmichthys …
