Overwinter survival of an estuarine resident fish (<i>Fundulus heteroclitus</i>) in <span>North Carolina</span> salt marsh creeks Open
The mummichog Fundulus heteroclitus is a trophically important fish inhabiting Atlantic coastal salt marshes, with few in situ estimates of overwinter survival throughout the species range. We estimated overwinter apparent survival rates o…

Longer exposure to warm water increases subsequent thermal tolerance of brook trout in cold water: acclimation timing and physiology Open
Climate change has resulted in increased incidence and variability of warming episodes in cold-water streams that support salmonids. The capacity to acclimate to warm temperatures may allow cold-water fish to persist in spite of changing t…

NOTES ON THE DIET OF THE GROUD SNAKES Pliocercus euryzonus AND Urotheca guentheri (SQUAMATA: DIPSADIDAE) FROM COSTA RICA Open
We report observations of the diet of two species of terrestrial snakes: Pliocercus euryzonus was observed feeding on an egg mass, probably from of Agalychnis callidryas, while Urotheca guentheri was observed feeding on the snake Ninia mac…

Smaller body size under warming is not due to gill-oxygen limitation in a cold-water salmonid Open
Declining body size in fishes and other aquatic ectotherms associated with anthropogenic climate warming has significant implications for future fisheries yields, stock assessments and aquatic ecosystem stability. One proposed mechanism se…

Using Environmental DNA to Reconstruct Amphibian Communities at Sites Infected with<i>Batrachochytrium salamandrivorans</i>in the Netherlands Open
A bstract The recently discovered Batrachochytrium salamandrivorans ( Bsal ) fungus can cause high mortality rates in some European salamanders and newts (urodelans) and has the potential to expand its currently small invasive range in Eur…

Keeping things local: Subpopulation <i>N</i><sub>b</sub> and <i>N</i><sub>e</sub> in a stream network with partial barriers to fish migration Open
For organisms with overlapping generations that occur in metapopulations, uncertainty remains regarding the spatiotemporal scale of inference of estimates of the effective number of breeders ( ) and whether these estimates can be used to p…

A hierarchical model of daily stream temperature using air-water temperature synchronization, autocorrelation, and time lags Open
Water temperature is a primary driver of stream ecosystems and commonly forms the basis of stream classifications. Robust models of stream temperature are critical as the climate changes, but estimating daily stream temperature poses sever…

Movement patterns of Brook Trout in a restored coastal stream system in southern Massachusetts Open
Coastal Brook Trout ( Salvelinus fontinalis ) populations are found from northern Canada to New England. The extent of anadromy generally decreases with latitude, but the ecology and movements of more southern populations are poorly unders…
