Congener Conflict: Invasive Barred Owl Landscape Use Across the Range of the Northern Spotted OwlNARA Subscribed
Aim To map the probability of landscape use of invading barred owls ( Strix varia ) across the range of the threatened northern spotted owl ( S. Occidentallis Caurina ) in the Pacific Northwest, USA , identifying environmental drivers of barred owl landscape use to inform targeted management interventions. Location Forests of the Pacific Northwest, USA. Taxon Barred Owl ( Strix varia ). Methods We deployed 4081 autonomous reco...
Rationale Compulsivity often develops during childhood and is associated with elevated glutamate levels within the frontostriatal system. This suggests that anti-glutamatergic drugs, like memantine, may be an effective treatment. Objective Our goal was to characterize the acute and chronic effect of memantine treatment on compulsive behavior and frontostriatal network structure and function in an adolescent rat model of compul...
Sugar Maple, Red Maple, and Yellow Birch Growth and Mortality in Even-Aged Adirondack Northern HardwoodsNARA Subscribed
Tree diameter growth models for northern hardwoods commonly used large data sets representing a composite of stands with varying management histories, structural characteristics, and age distributions. Yet common predictor variables like diameter can show differences in growth patterns for stands with different age structures and management histories. To address that, we modeled growth and mortality for sugar maple, red maple,...
Long‐term datasets can be particularly useful for parsing out factors influencing populations, yet few studies have utilized continuous datasets to quantify population dynamics in bivalve molluscs. We used dynamic factor analysis on a clam biomass dataset spanning 28 yr and five distinct regions in the southern Salish Sea to determine (1) if native intertidal clam populations exhibit synchrony and (2) what environmental covari...
Salish Sea Chinook salmon exhibit weaker coherence in early marine survival trends than coastal populationsNARA Subscribed
Identifying factors that influence anadromous Pacific salmon ( Oncorhynchus spp.) population dynamics is complicated by their diverse life histories and large geographic range. Over the last several decades, Chinook salmon ( O. tshawytscha ) populations from coastal areas and the Salish Sea have exhibited substantial variability in abundance. In some cases, populations within the Salish Sea have experienced persistent declines...
EPMA-World Congress 2015NARA Subscribed
The Columbia River Basin (Basin) is located in the Pacific Northwest, United States. The 370 hydroelectric dams in the Basin provide the Pacific Northwest with many services including hydropower generation, flood control, agricultural irrigation and navigation. The basin also provides habitat for a variety of anadromous and resident fishes and wildlife species. Balancing the energy demands with the needs of fish and wildlife i...
