Is Mitigation Translocation An Effective Strategy For Conserving Common Chuckwallas?, Chad A. Rubke, Daniel J. Leavitt, Woodrow L. Crumbo, Brock Williams, Ashley A. Grimsley-Padron, Kristin J. Gade, Russell Benford, Michael F. Ingraldi, Brian K. Sullivan, Ryan P. O’Donnell

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 …

Due to their secretive nature, snakes are the most challenging animal group for monitoring. Nevertheless, population size estimates are indispensable to accurately determining conservation status and management strategies. We used passive integrated transponder (PIT) tags to track aquatic snakes Natrix natrix and Natrix tessellata in Lake Işıklı, Denizli province, Turkey. 304 N. natrix and 1563 N. tessellata specimens were captured and marked over the four-year sampling period. Of the marked individuals, 14 N. natrix and 97 N. tessellata were recaptured at least once. The three-year average population size was estimated at 1940 ± 1055 for N. natrix, and 10,146 ± …

Gulf and Caribbean Research

Current abundance estimates for populations of common bottlenose dolphins (Tursiops truncatus, Montagu, 1821) in bays, sounds, and estuaries are lacking throughout most of the northwestern Gulf of Mexico, including areas of Texas and western Louisiana. To address this issue, we conducted 92 small-boat photographic identification surveys covering ~2000 km2 and comprising ~11,000 km of track-line in winter and summer seasons in West Bay, TX (2014 – 2015, n = 25), the Galveston Bay, TX system (2016, n = 50), Sabine Lake, TX (2017, n = 17), and adjacent coastal waters. Individual dolphin encounter histories were constrained by …
