Documenting trans-Himalayan migration through satellite telemetry: A report on capture, deployment, and tracking of bar-headed goose (Anser indicus) Documenting trans-Himalayan migration through satellite telemetry: A report on capture, deployment, and tracking of bar-headed goose (Anser indicus)
Animal movement and migration studies have made significant progress with the use of telemetry. Conventional radio telemetry has been used in numerous studies in different regions. However, the use of this technology is restricted to species with limited range of movement. Applying this tool for long distance migrants is usually unsatisfactory. Other challenges such as hilly terrain or...

The genetics of amphibian decline: population substructure and molecular differentiation in the Yosemite toad, Bufo canorus (Anura, Bufonidae) based on single-strand conformation polymorphism analysis (SSCP) and mitochondrial DNA sequence data The genetics of amphibian decline: population substructure and molecular differentiation in the Yosemite toad, Bufo canorus (Anura, Bufonidae) based on single-strand conformation polymorphism analysis (SSCP) and mitochondrial DNA sequence data
We present a comprehensive survey of genetic variation across the range of the narrowly distributed endemic Yosemite toad Bufo canorus, a declining amphibian restricted to the Sierra Nevada of California. Based on 322 bp of mitochondrial cytochrome b sequence data, we found limited support for the monophyly of B. canorus and its closely related congener B. exsul to the exclusion of the...

Inter-decadal change in diet and population of sea otters at Amchitka Island, Alaska Inter-decadal change in diet and population of sea otters at Amchitka Island, Alaska
After having been hunted to near-extinction in the Pacific maritime fur trade, the sea otter population at Amchitka Island, Alaska increased from very low numbers in the early 1900s to near equilibrium density by the 1940s. The population persisted at or near equilibrium through the 1980s, but declined sharply in the 1990s in apparent response to increased killer whale predation. Sea...

Restoration with smoke-dependent species Restoration with smoke-dependent species
Examination of blood films from wood ducks (Aix sponsa) from several northeastern states revealed Haemoproteus, Leucocytozoon, Plasmodium and a typanosome. Haemoproteus occurred in all areas sampled and birds of the year from Massachusetts demonstrated the highest incidence during the last 2 weeks in August. Leucocytozoon was most prevalent in more northern areas. P. circumflexum and a

Composition of Pteryxia terebinthina var. californica (Coult. and Rose) Mathias essential oils Composition of Pteryxia terebinthina var. californica (Coult. and Rose) Mathias essential oils
β-Pinene (35.0%, 53.8%) was the major component of both the aerial parts and the root oils of Pteryxia terebinthina var. californica, respectively. β-Phellandrene (12.2%) was the other most abundant component of the oil from aeial parts while δ-3-carene (14.2%) was the second abundant component of the root oil.
