Freshwater fish such as white sturgeon (Acipenser transmontanus) are particularly vulnerable to the effects of anthropogenically induced global warming. Critical thermal maximum tests (CTmax) are often conducted to provide insight into the impacts of changing temperatures; however, little is known about how the rate of temperature increase in these...

Ants often interact with other invertebrates as predators or mutualists. Epiphytic bromeliads provide nesting sites for ants, and could increase ant abundances in the tree canopy. We surveyed ants in the foliage of orange trees that either hosted bromeliads or did not. To determine if observed associations between bromeliads and tree ants were caus...

We investigated whether individual rainbow trout (Oncorhynchus mykiss; 9–53 g) avoid a potentially lethal level of total dissolved gas (TDG) supersaturation using lateral movements during an acute exposure. As there is no mechanism by which fish can detect and avoid TDG supersaturation in shallow water, we hypothesize that rainbow trout do not dire...

Individual species can have profound effects on ecological communities, but, in hyperdiverse systems, it can be challenging to determine the underlying ecological mechanisms. Simplifying species’ responses by trophic level or functional group may be useful, but characterizing the trait structure of communities may be better related to niche process...
