Abstract:
... Steelhead trout (Oncorhynchus mykiss) of four different sizes (27.06 ± 4.27, 75.99 ± 10.48, 140.21 ± 22.08, and 224.72 ± 31.20 g) were cultured for two weeks at four different temperatures (8 °C, 12 °C, 16 °C, and 20 °C) to evaluate the effects of temperature on gastric evacuation (GE) and the associated mathematical models. The wet and dry mass within the stomach contents of the steelhead trout w ...

Abstract:
... Imperfect detection is a common issue affecting the accuracy of surveys that quantify animal abundance and distribution. To quantify detectability, counts are often calibrated to independent measures of abundance (e.g., via mark-recapture) but stochastic sampling variability in both data types is not typically accounted for. This practice may cause detectability to be quantified inaccurately and l ...
