چکیده

Studies quantifying habitat structure generally use several instruments. This paper aims to propose a new and efficient device to characterize microhabitat structure of small mammals. Seven measurements were taken: plant cover, litter cover, rock cover, canopy cover, and vegetative obstruction at three heights. The device is a 0.25 m2 square wooden frame (0.50 m x 0.50 m) divided in to 100 open squares by wire mesh. Average time spent to measure each trapping station was six minutes. This new device is efficient, i.e., quick, practical, simple, and reliable. It can be used in any kind of forest. We propose this method as a standard method to describe habitat structure.

Effect of Downed Woody Debris on Small Mammal Anti-Predator Behavior

The threat of predation is often the largest cost associated with foraging (Brown & Kotler 2004; Preisser et al. 2005; Creel & Christianson 2008). Foragers primarily assess the threat of predation based on indirect cues of risk, such as microhabitat features and environmental conditions (Orrock et al. 2004; Verdolin 2006). For example, small mammals often respond to the threat of predation by b...

Introduction: One of the ways of restoration and reclamation of damaged rangeland is to use different methods of rain harvesting such as pitting, counter furrowing, flood spreading, small arc basins system and etc., along with the reduction of runoff, it increases the soil moisture content and thus increases vegetation cover. Biodiversity is most commonly used to describe the number of species....

Microhabitat Selection for Nesting and Brood-rearing by the Greater Sage-grouse in Xeric Big Sagebrush

Understanding selection of breeding habitat is critical to conserving and restoring habitats for the Greater Sage-Grouse (Centrocercus urophasianus), particularly in xeric landscapes (≤25 cm annual precipitation). We monitored radio-marked female sage-grouse in south-central Wyoming in 2008 and 2009 to assess microhabitat use during nesting and brood rearing. For each model we grouped variables...
