ABSTRACT There is little information on predator–prey interactions in wind energy landscapes North America, especially among terrestrial vertebrates. Here, we evaluated how proximity to roads and turbines affect mesocarnivore visitation with desert tortoises ( Gopherus agassizii ) their burrows a landscape. In 2013, placed motion‐sensor cameras facing the entrances of 46 active tortoise 5.2‐km 2 facility near Palm Springs, California, USA. Cameras recorded images 35 species reptiles,...
The diamond-backed terrapin (Malaclemys terrapin) is a small estuarine turtle distributed along the Atlantic and Gulf Coasts of USA. Terrapin populations are declining throughout their range one main causes mortality by drowning as bycatch in commercially-fished blue crab (Callinectes sapidus) traps (aka pots). We conducted head counts terrapins documented distribution number pots on Savannah Coastal Refuges Complex southeast Georgia, Using an index for representing relative degree crabbing...
Agassiz's desert tortoise (Gopherus agassizii) reaches the southern edge of its range in Sonoran Desert California. The reproductive ecology this wideranging species is understudied here compared to populations adjacent Mojave Desert. Understanding potential geographic variation important for effective management conservation-reliant like G. agassizii. We studied fecundity and clutch phenology female agassizii at two study sites region Joshua Tree National Park over five years (1997–1999,...
Abstract Context Camera trapping is increasingly used to collect information on wildlife occurrence and behaviour remotely. Not only does the technique provide insights into habitat use by species of interest, it also gathers non-target species. Aims We implemented ground-based camera investigate behaviours ground-dwelling birds, a that has largely been unutilised for studying especially in wind-energy facilities. Methods traps monitor activities Agassiz’s desert tortoises (Gopherus...
La tortuga de estanque del suroeste (Actinemys pallida) es una semiacuática que, vez en cuando, pasa tiempo la tierra para asolearse, ovipositar, realizar movimientos intermitentes e hibernar tierra. El uso ambos medios, acuático y terrestre, expone a las tortugas semiacuáticas un mayor riesgo lesiones o mortalidad por inundaciones, intentos depredación otros peligros ambientales (por ejemplo, actividades humanas, tales como choques vehiculares, etc.). Recolectamos datos anormalidades...
Understanding the influence of geographic features on evolutionary history and population structure a species can assist wildlife managers in delimiting genetic units (GUs) for conservation management. Landscape including mountains, low elevation depressions, even roads connectivity gene flow among Agassiz’s desert tortoise (Gopherus agassizii) populations. Substantial changes landscape American Southwest occurred during last six million years (including formation Gulf California lower...
The painted turtle (Chrysemys picta) is widely distributed from coast to in North America with each of four subspecies generally occupying different regions. In the southwestern USA and northern Mexico, where C. p. bellii expected native race, populations are small widelyscattered. Introduced other reported various locations USA. We discovered a but dense introduced population marginata on Colorado Plateau Arizona, region few, if any, turtles due aridity an elevated topography little surface...
