Broad timescale forcing and geomorphic mediation of tidal marsh flow and temperature dynamics
Christopher Enwright, Steven Culberson, Jon R. Burau
2013, Estuaries and Coasts (36) 1319-1339
Tidal marsh functions are driven by interactions between tides, landscape morphology, and emergent vegetation. Less often considered are the diurnal pattern of tide extremes and seasonal variation of solar insolation in the mix of tidal marsh driver interactions. This work demonstrates how high-frequency hydroperiod and water temperature variability emerges from...
The ovenbird (Seiurus aurocapilla) as a model for testing food-value theory
Henry M. Streby, Sean M. Peterson, Brian Scholtens, Adrian P. Monroe, David E. Andersen
2013, The American Midland Naturalist (169) 214-220
Food-value theory states that territorial animals space themselves such that each territory contains adequate food for rearing young. The ovenbird (Seiurus aurocapilla) is often cited as a species for which this hypothesis is supported because ovenbird territory size is inversely related to ground-invertebrate abundance within territories. However, little is known...

Fish population failure caused by an environmental estrogen is long-lasting and regulated by direct and parental effects on survival and fecundity
Adam R. Schwindt, Dana L. Winkelman
2013, Thesis, The population ecology of fathead minnows (<i>Pimephales promelas</i>) in estrogen contaminated environments
Despite significant research demonstrating effects of estrogens such as 17α - ethinylestradiol (EE2) on fish, the underlying mechanisms regulating population failure are unknown. Projected water shortages could leave waterways increasingly dominated by wastewater effluent and understanding mechanisms is necessary for conservation and management. Here we identify mechanisms of...

Seed harvesting is influenced by associational effects in mixed seed neighbourhoods, not just by seed density
Steven M. Ostoja, Eugene W. Schupp, Susan Durham, Robert C. Klinger
2013, Functional Ecology (27) 775-785
Rodents frequently forage in a density-dependent manner, increasing harvesting in patches with greater seed densities. Although seldom considered, seed harvesting may also depend on the species identities of other individuals in the seed neighbourhood. When the seed harvest of a focal species increases in association with another...
