Phytophthora species were systematically sampled, isolated, identified and compared for presence in streams, soil and roots of alder (Alnus species) dominated riparian ecosystems in western Oregon. We describe the species assemblage and evaluate Phytophthora diversity associated with alder. We recovered 1250 isolates of 20 Phytophthora species. Only three species were...
Here we present a phylogeny of beetles (Insecta: Coleoptera) based on DNA sequence data from eight nuclear genes, including six single-copy nuclear protein-coding genes, for 367 species representing 172 of 183 extant families. Our results refine existing knowledge of relationships among major groups of beetles. Strepsiptera was confirmed as sister...

Remote autonomous ecological acoustic recorders (EARs) were deployed in deep waters at five locations around the island of Kauai and one in waters off Ni'ihau in the main Hawaiian island chain. The EARs were moored to the bottom at depths between 400 and 800 m. The data acquisition sampling rate...
The mortality of discarded bycatch is a critical problem in the management of fisheries worldwide. Little is known about the key principles involved in the mortality of discarded bycatch. These principles are best elaborated under controlled conditions in the laboratory where the actions and interactions of stressors found in fishing...
Prior research has revealed evidence for both proximity seeking and relational distancing following interpersonal rejection (Williams, 2007). The present study explored evidence for both processes in the context of face-to-face interactions. Participants were accepted or rejected by one person then asked to interact with a new relationship partner for the...
Atrazine (ATZ) is a selective triazine herbicide used primarily for pre-emergent weed control in corn, sorghum and sugar cane production. It is one of the most widely used herbicides in North America. Some research published over the last decade suggests that chronic exposure to environmentally relevant ATZ concentrations can adversely...
Field surveys in 2006 confirmed that the
exotic rust fungus Phragmidium violaceum was widespread
on Rubus armeniacus and Rubus laciniatus in
the Pacific Northwest of the USA. The origin and
dispersal pattern of this obligate biotrophic pathogen in
the USA were investigated by comparing the genetic
diversity and structure of...
Potentially relevant literature for the years 1990-1999 was identified by (a) conducting keyword searches of computerized bibliographic databases, especially CAB Abstracts and Aquatic Sciences and Fisheries Abstracts, (b) reading through the tables of contents of a few especially relevant journals, (c) searching the internet for pertinent bibliographies, and (d) to...
