TAML activators promise a novel water treatment approach
by efficiently catalysing peroxide-based degradation of
chemicals of high concern at environmental concentrations.
Green design ethics demands an exploration of TAML
toxicity. Exposure to high concentrations of certain activators
caused adverse effects in zebrafish. At typical TAML
operational concentrations, development was not...
Body size is known to correlate with many aspects of life history in birds, and this knowledge can be used to manage and conserve bird species. However, few studies have compared the wintering ecology of sympatric subspecies that vary significantly in body size. We used radiotelemetry to examine the relationship...
Velocity measurements from 17 deployments of moored acoustic Doppler current
profilers obtained during four summer upwelling seasons are used to describe the crossshelf
divergence of Ekman transport in the inner shelf off Oregon. For each deployment
the measured surface and bottom cross-shelf transports were compared with estimates
of the theoretical...
Introduction: Biotic soil crust communities contribute valuable ecosystem services and biodiversity in steppe ecosystems. The uncommon crust lichens Acarospora schleicheri, Fuscopannaria cyanolepra, Rhizocarpon diploschistidina, and Texosporium sancti-jacobi are associated with fine-textured soils along rivers of the Columbia Basin. A. schleicheri and R. diploschistidina indicate late-successional habitat and may serve as...
There has been much discussion in the conservation and policy realms of COVID-19 as a zoonotic disease, or a disease transmitted from wildlife to humans. However, wildlife consumption in China is not only a potential source of disease but also a practice embedded in complex beliefs about health. This paper...
Phytoplankton biomass in high-nitrate, low-chlorophyll (HNLC) ocean regions exhibits a pronounced stability: variation occurs only within a narrow range of values. The magnitude of this variation has profound ecological and geochemical consequences. While mechanisms believed to set the upper limits to HNLC phytoplankton biomass (iron limitation, microherbivore grazing) have received...
In a previous article, Beschta et al. (Environ
Manag 51(2):474–491, 2013) argue that grazing by large
ungulates (both native and domestic) should be eliminated
or greatly reduced on western public lands to reduce
potential climate change impacts. The authors did not
present a balanced synthesis of the scientific literature, and...
Time series of flow were measured across the inner surf zone during a storm. These data were used to quantify the dependence of wave height (transformed from measured flow) and velocity on local slope and depth. Similar to previous studies, as incident waves broke and propagated into the surf zone,...
In 1984-1986, Bayer made 171 and 67 waterbird censuses at West Pond and East Pond, respectively. From 1974 through June 1992, Bayer and others also made an additional 138 and 110 observations at West Pond and East Pond, respectively. A total of 48 waterbird taxa were reported at West Pond,...
Viral infections were investigated in American black bears (Ursus americanus) from Nevada and northern California with and without idiopathic encephalitis. Metagenomics analyses of tissue pools revealed novel viruses in the genera Circoviridae, Parvoviridae, Anelloviridae, Polyomaviridae, and Papillomaviridae. The circovirus and parvovirus were of particular interest due to their potential importance...
