In the Pacific Northwest ecoregion of North America, sculpins represent a major constituent of freshwater assemblages in coastal rivers. Based on their prevalence and abundance, sculpins are likely important ecologically, yet little is known of their interactions with co-occurring species, such as widely studied salmon and trout (salmonines). In this...
Many ecological populations can be interpreted as response surfaces; the spatial
patterns of the population vary in response to changes in the spatial patterns of
environmental explanatory variables. Collection of a probability sample from the
population provides unbiased estimates of the population parameters using design
based estimation. When information is...
The present work shows predatory behavior of the social orb-weaver spider, Geratonephila burmanica n. gen., n. sp. (Araneae: Nephilidae) against a parasitic wasp, Cascoscelio incassa n. gen., n. sp., (Hymenoptera: Platygasteridae) in Early Cretaceous Burmese amber. An adult male and juvenile of Geratonephila burmanica n. gen., n. sp. in the...
A genecological approach was used to explore genetic variation in adaptive traits in Pseudoroegneria spicata, a key restoration grass, in the intermountain western United States. Common garden experiments were established at three contrasting sites with seedlings from two maternal parents from each of 114 populations along with five commercial releases...
The Baculoviridae comprise a diverse group of occluded DNA viruses that contain large double-stranded DNA genomes of 80 - 180 kb and may encode up to 180 gene products. To understand how baculoviruses replicate and process their genomes and the gene products that are involved in these events, a series...
This phenomenological inquiry explored dimensions of reflection for older adults in a developmental oriented adventure education experience. Data were gathered from emergent interviews with four individuals while participating in a multi-day, self-contained experiential education program conducted in a rugged environment, and led by a Navajo leader. Two principle research questions...
