The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important...
Size-structured spatial patterns in larvae of 2 sucker and 3 minnow species are described from fixed-site
sampling in Upper Klamath Lake, Oregon, and are used to demonstrate patterns of size-based losses downstream and
retention in the lake. The smallest larvae of shortnose suckers (Chasmistes brevirostris), Lost River suckers (Deltistes
luxatus),...

Serum samples were collected between 24 and 48 h of age
from 408 Hereford calves of a selection experiment and from 200
Angus, Hereford and Red Poll calves of another experimental
population (Germ Plasm Utilization project). Concentrations of
Immunoglobulin G₁ (IgG₁) were determined by single radial

A programming paradigm can be defined as a model or an approach employed
in solving a problem. The results of the research described in this document demonstrate
that it is possible to unite several different programming paradigms into a
single linguistic framework. The imperative, procedural, applicative, lambda-free,
relational, logic and...
Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could
be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by
females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand
factors affecting...
This thesis is an effort to formalize and document some of the changes occuring in the Warwar Valley of Gongola State, Nigeria, West Africa. The documentation will comprise a photographic study over time accompanied by an ethnographic narrative. Information gathered from photographic images, field notes and the anthropological record will...
