Community Structure of Desert Small Mammals: Comparisons across Four Continents1

Presencelabsence data for the small-mammal species at sites in seven deserts were analyzed for evidence of similarity in community structure. The deserts studied were located in North and South America (268 and 118 sites, respectively), Australia (245 sites), Israel (54 sites), and greater Eurasia (Thar, 15 sites; Turkestan, 36 sites; Gobi, 98 sites). Patterns observed in all deserts included: ...

Small Mammals

A variety of terrestrial small mammals with diverse size, form, geographic range, and ecological niche inhabit southern forests. Some are highly specialized for their environment, such as the semi-aquatic species or fossorial species, such as moles. Some, such as the cotton rat, are widely distributed throughout the region and others highly restrictive in their range and habitat. Because of the...

Anesthesia in Wild Small Mammals

Overview The purpose of this guide is to provide information and serve as a refresher for veterinarians and wildlife biologists who have prior experience with anesthesia and as a training tool for those learning anesthesia under supervision. Anesthesia is loss of sensation, with or without loss of consciousness. General anesthesia is a drug-induced state of total unconsciousness. Anesthesia is ...

Small regulatory RNAs in mammals.

Mammalian cells harbor numerous small non-protein-coding RNAs, including small nucleolar RNAs (snoRNAs), microRNAs (miRNAs), short interfering RNAs (siRNAs) and small double-stranded RNAs, which regulate gene expression at many levels including chromatin architecture, RNA editing, RNA stability, translation, and quite possibly transcription and splicing. These RNAs are processed by multistep pa...
