Fence types influence pronghorn movement responses

چکیده
Abstract Impediments that constrain animal movements across spatiotemporally heterogeneous landscapes can result in reduced or complete loss of access to critical resources. Across their range North America, pronghorn ( Antilocapra americana ) are exposed fences affect ability permeate the landscape, resources, and respond climatic variations. Understanding movement responses is essential for improving landscape permeability; however, prior studies provide only limited insight due lack information on fence characteristics small sample sizes. Our study used hourly collar locations from adult female six herds Montana, USA, identified encounters with mapped evaluate three (i.e., probability an unaltered initial response, crossing following altered passage time response) as a function attributes. Based 5581 pathways 265 collared 979 km fences, we found variability response was correlated type. Woven wire substantially increased times compared low average lowest height <41 cm) high ≥41 strand fences. Both elicited similar being relatively permeable at encounter permeability thereafter. Fence probabilities through modestly but negligibly woven averaging approximately 14 h. Pronghorn knowledge fidelity specific along which may be inconsistent stretch, likely allow some most regardless height, permeable. Improving should focus removing replacing incorporating variation heights into new designs modifications existing

Two Types of Remnant Movement
This article is concerned with stating and accounting for differences between two types of remnant movement that have been proposed in the literature. Remnant movement is movement of an XP β from which extraction of α has taken place earlier in the derivation; cf. (1). This phenomenon has been argued to support a derivational approach to syntax (cf. Chomsky (1998)): Since remnant movement creat...
متن کاملComparing Habitat Suitability and Connectivity Modeling Methods for Conserving Pronghorn Migrations
Terrestrial long-distance migrations are declining globally: in North America, nearly 75% have been lost. Yet there has been limited research comparing habitat suitability and connectivity models to identify migration corridors across increasingly fragmented landscapes. Here we use pronghorn (Antilocapra americana) migrations in prairie habitat to compare two types of models that identify habit...
متن کاملModeling Fence Location and Density at a Regional Scale for Use in Wildlife Management
Barbed and woven wire fences, common structures across western North America, act as impediments to wildlife movements. In particular, fencing influences pronghorn (Antilocapra americana) daily and seasonal movements, as well as modifying habitat selection. Because of fencing's impacts to pronghorn and other wildlife, it is a potentially important factor in both wildlife movement and habitat se...
متن کاملInfluence of Habitat and Intrinsic Characteristics on Survival of Neonatal Pronghorn
Increased understanding of the influence of habitat (e.g., composition, patch size) and intrinsic (e.g., age, birth mass) factors on survival of neonatal pronghorn (Antilocapra americana) is a prerequisite to successful management programs, particularly as they relate to population dynamics and the role of population models in adaptive species management. Nevertheless, few studies have presente...
