Patterns of Breeding Songbird Diversity and Occurrence in Riparian Habitats of the Eastern Sierra Nevada

We determined several vegetation and environmental features that predicted breeding bird species diversity and focal species occurrence in riparian habitats across three watersheds of the eastern Sierra Nevada bioregion, California. Conducting point counts and associated vegetation assessments at 480 individual riparian points between 1998 and 2000 permitted us to investigate bird and habitat r...

Polyhalite microfabrics in an Alpine evaporite mélange: Hallstatt, Eastern Alps

In the Hallstatt salt mine (Austria), polyhalite rocks occur in 0.5-1 m thick and several metre long tectonic lenses within the protocataclasite to protomylonite matrix of the Alpine Haselgebirge Fm.. Thin section analysis of Hallstatt polyhalites reveals various fabric types similar to metamorphic rocks of crust-forming minerals, e.g. quartz and feldspar. Polyhalite microfabrics from Hallstatt...

Foreshock Probabilities in the Western Great-basin Eastern Sierra Nevada

We quantify foreshock occurrence probabilities by applying the empirical technique of Jones (1985) to the western Nevada and eastern California earthquake catalog compiled by the University of Nevada, Reno, from 1934 through 1991. The foreshock occurrence rates depend heavily on the parameters used to remove aftershocks from the catalog. It is necessary to separate the Mammoth/Mono region from ...

Ecology of the Scorpion, Microtityus jaumei in Sierra de Canasta, Cuba

An assessment of the population dynamics of Microtityus jaumei Armas (Scorpiones: Buthidae) on the slopes south of Sierra de Canasta, Guantánamo Province, Cuba show an increase in activity over the year (≤ 0.05). The activity peak is related to the reproductive period from June to November. The abundance of scorpions was significantly related to density of the canopy and thickness of the substr...
