Conservation Assessment for the Red-Tailed Chipmunk
... The red-tailed chipmunk is comprised of two distinct subspecies, each with its own distinctive bacular morphology, and some researchers have proposed breaking the two subspecies into two species based in part on this characteristic (Patterson and Heaney 1987, Nagorsen et al. 2000). However, the sub ...

Threats and biodiversity in the mediterranean biome

Habitat conservation
Habitat conservation is a land management practice that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
