Human–Wildlife Interactions
Mitigation translocation remains a popular conservation tool despite ongoing debate regarding its utility for population conservation. To add to the understanding of the effectiveness of mitigation translocation, in 2017 and 2018 we monitored a population of protected common chuckwallas (Sauromalus ater) following translocation away from the area of construction of a new highway near the South Mountains, Phoenix, Arizona, USA. We removed chuckwallas from the construction right-of-way, paint-marked and pit-tagged them, and then released them in a nearby municipal preserve. We deployed very high frequency radio-telemetry transmitters on a sub-sample of 15 translocated adult chuckwallas. We monitored the …
Influence Of Removal Sampling Of Small Mammals On Abundance And Diversity Attributes: Scientific Implications, Thomas P. Sullivan, Druscilla S. Sullivan
Influence Of Removal Sampling Of Small Mammals On Abundance And Diversity Attributes: Scientific Implications, Thomas P. Sullivan, Druscilla S. Sullivan
Human–Wildlife Interactions
Terrestrial small mammals occupy a variety of temperate and boreal forests in North America and Eurasia and contribute to biodiversity within these ecosystems. Researchers commonly use a variation of removal trapping to sample small-mammal populations and communities in these systems. However, it is not known if recurrent removal sampling might bias abundance estimates or alter the very populations under study. We addressed 2 questions: (1) are estimates of population size and species richness and diversity gained from removal trapping different from those based on live-trapping? and (2) what residual impact does removal trapping have on small-mammal populations and communities, as …
Comparison Of Sampling Strategies To Estimate Abundance Of Double-Crested Cormorants In Western Mississippi, Aaron T. Pearse, Brian S. Dorr, Stephen J. Dinsmore, Richard M. Kaminski
Comparison Of Sampling Strategies To Estimate Abundance Of Double-Crested Cormorants In Western Mississippi, Aaron T. Pearse, Brian S. Dorr, Stephen J. Dinsmore, Richard M. Kaminski
Human–Wildlife Interactions
We compared 2 sampling strategies designed to estimate abundance of double-crested cormorants (Phalacrocorax auritus, hereafter cormorants) on aquaculture ponds in western Mississippi. Cormorants are a major predator of cultured channel catfish (Ictalurus punctatus) in this region; thus, estimating cormorant abundance is needed to better determine their economic impact. We independently designed a species-specific survey (i.e., cluster sampling) and a general survey (i.e., transect sampling) based on robust probability sampling theory to estimate abundance of this target population. During winters 2002–2003 and 2003–2004, we conducted 8 pairs of surveys and compared estimates of cormorant abundance and associated …
