Habitat selection is the process by which individuals choose among available habitat patches. Habitat availability” as how accessible and procurable physical and biological components of a habitat are to animals. Research on small mammal habitat use helps to broaden their knowledge. Small mammals are often used as an indicator species group to reflect some aspects of “integrity. Small mammal ab...

We present a hands-on outdoor activity coupled with classroom discussion to teach students about wildlife habitat selection, the process by which animals choose where to live. By selecting locations or habitats with many benefits (e.g., food, shelter, mates) and few costs (e.g., predators), animals improve their ability to survive and reproduce. Biologists track animal movement using radio tele...

Differences between taxa which have developed in allopatry can contribute to reproductive isolation in the case of secondary contact. Hybrid zones are ideal study systems in which to investigate the role of preand postzygotic mechanisms for the reduction or inhibition of gene flow. This thesis describes a hybrid zone between the fire-bellied toads Bombina bombina and B. variegata in Romania. Th...

animals move in response to a variety of competing pressures such as the need to feed, avoid predators, breed, and rear offspring (Brown et al. 1999, Cresswell 2008). These competing demands give rise to trade-offs that individuals must mediate through their space use and movements (Lima 1998, Hebblewhite and Merrill 2009), resulting in distinctive patterns of habitat selection. Numerous studie...
