The Columbia River delivers the greatest amount of freshwater to the coastal ocean along the U.S. Pacific coast. This freshwater forms the Columbia River plume, a mesoscale plume with significant implications on coastal ocean physical, biological, chemical, and geological processes. The plume is transported south and offshore during the upwelling...
Anthropogenic modification watersheds and climate change have altered export from fluvial systems causing changes to the carbonate chemistry of river-influenced near shore environments. To determine the possible effects of riverine discharges on the mussel Perumytilus purpuratus, we performed in situ transplant experiments between river-influenced and open coastal habitats with contrasting...
Freshwater discharge affects the biogeochemistry of river-influenced nearshore environments by contributing with carbon and nutrients. An increase in human activities in river basins may alter the natural riverine nutrients and carbon export to coastal ecosystems. Along a wide latitudinal range (32° 55'S-40° 10'S), this study explores the role of climate...
The effects of potential parental egg production and
environmental factors on year-class strength (YCS) of petrale sole
(Eopsetta jordani) were investigated in two areas off Oregon and
Washington (Pacific States Marine Fisheries Commission areas 2B: 42°
50'N - 44°18'N, and 3A: 45° 46'N - 47°20'N). Indices of YCS based on...
The extent of biological invasions, their role on the feeding of
native fishes and their impact on community stability were
investigated in Alsea Bay and Yaquina Bay, two estuaries on the
central Oregon coast, USA. Most nonindigenous species (NIS)
introduced in these intermediately invaded estuaries are
considered byproducts of culturing...
A multidisciplinary western Beaufort Sea Ecological Cruise
(WEBSEC) was conducted from August 15 to September 20, 1971.
During the cruise, one hundred ninety-nine 0.1 m² Smith-McIntyre
grabs samples were taken at forty stations located on the continental
shelf and slope of the western Beaufort Sea. The Gammaridean
Amphipoda and Cumacea...
The growing urban development and the inadequate installation of settlements has caused environmental challenges such as landscape destruction, loss of urban tree biodiversity, therefore, the objective of this study was to identify the ecosystem services of urban trees in the 'Monumental Zone' of the city of Iquitos, in the Peruvian...
Overfishing has been cited as a major cause of sea bass population decline and recent scientific analyses have reinforced previous concerns of unsustainable fishing advising urgently for a substantial reduction in fishing mortality. For the first time, 2013, the ICES released an analytical advice on the status of the European...
Shelf-life is the time period during which products retain market-acceptable quality while meeting legal and safety requirements. Deterministic models yield single value estimations of shelf-life typically based on average or worst-case values for input parameters. In deterministic calculations, considering the input parameter variability can be challenging. In this study, a...
Aim: The ecological effects of biological invasions are well documented, but little
is known about the effects of invaders on the genetic structure of native
species. We examined the phylogeography, genetic variation and population
structuring of two galaxiid fishes, Aplochiton zebra and A. taeniatus, threatened
by non-native salmonids, and whose...
