Joint estimation of habitat dynamics and species interactions: Disturbance reduces co-occurrence of non-native predators with an endangered toad
David A.W. Miller, Cheryl S. Brehme, James E. Hines, James D. Nichols, Robert N. Fisher
2012, Journal of Animal Ecology (81) 1288-1297
1. Ecologists have long been interested in the processes that determine patterns of species occurrence and co-occurrence. Potential short-comings of many existing empirical approaches that address these questions include a reliance on patterns of occurrence at a single time point, failure to account properly for imperfect detection and treating the environment...
Chlorophacinone residues in mammalian prey at a black-tailed prairie dog colony
Nimish B. Vyas, Craig S. Hulse, Clifford P. Rice
2012, Environmental Toxicology and Chemistry (31) 2513-2516
Black-tailed prairie dogs (BTPDs), Cynomys ludovicianus, are an important prey for raptors; therefore, the use of the rodenticide Rozol (0.005% chlorophacinone active ingredient) to control BTPDs raises concern for secondary poisonings resulting from the consumption of contaminated prey by raptors. In the present study, the authors observed Rozol exposure...
Invertebrate and fish assemblage relations to dissolved oxygen minima in lowland streams of southwestern Louisiana
B. G. Justus, Scott V. Mize, Daniel Kroes
2012, River Research and Applications (30) 11-28
Dissolved oxygen (DO) concentrations in lowland streams are naturally lower than those in upland streams; however, in some regions where monitoring data are lacking, DO criteria originally established for upland streams have been applied to lowland streams. This study investigated the DO concentrations at which fish and invertebrate assemblages...
Bankfull-channel geometry and discharge curves for the Rocky Mountains Hydrologic Region in Wyoming
Katharine Foster
2012, Scientific Investigations Report 2012-5178
Regional curves relate bankfull-channel geometry and bankfull discharge to drainage area in regions with similar runoff characteristics and are used to estimate the bankfull discharge and bankfull-channel geometry when the drainage area of a stream is known. One-variable, ordinary least-squares regressions relating bankfull discharge, cross-sectional area, bankfull width, and bankfull...

The effect of leaf beetle herbivory on the fire behaviour of tamarisk (Tamarix ramosissima Lebed.)
Gail M. Drus, Tom L. Dudley, Matthew L. Brooks, John R. Matchett
2012, International Journal of Wildland Fire (22) 446-458
The non-native tree, Tamarix spp. has invaded desert riparian ecosystems in the south-western United States. Fire hazard has increased, as typically fire-resistant native vegetation is replaced by Tamarix. The tamarisk leaf beetle, Diorhabda carinulata Desbrochers, introduced for biological control, may affect fire behaviour by converting hydrated live Tamarix leaves and...
