Latitudinal Variation in Seasonal Activity and Mortality in Ratsnakes (Elaphe obsoleta)
The ecology of ectotherms should be particularly affected by latitude because so much of their biology is temperature dependent. Current latitudinal patterns should also be informative about how ectotherms will have to modify their behavior in response ...

Are grassland passerines especially susceptible to negative transmitter impacts?
Assessing the impacts of manipulative research can be hard when few animals are affected in any one study. Collating information across studies, however, can identify vulnerable organisms and allow researchers to tailor research to reduce, and possibly ...

Testing radiotransmitter attachment techniques on northern bobwhite and chukar chicks
We compared 4 external radiotransmitter attachment techniques to determine the optimum attachment method on chicks of 2 galliform species. The attachment methods included tissue glue, silicone gel, suturing, and leg harness.

Use of private lands for foraging by California spotted owls in the central Sierra Nevada
The use of private land by owls has long been of interest to wildlife managers in the Sierra Nevada, California, USA, because private lands could contribute to owl conservation if it is used extensively. Therefore, we studied the use of private lands for

Technology Management with Focus on Fish Transposition System (FTS) [PDF]
Fish transposition mechanisms have been installed near hydroelectric busses in order to reconnect sections of sectioned rivers and attract fish, offering them a route for the continuity of their displacement, essential for their feeding and reproduction.
