Optics, structure and variability of the offshore Columbia River plume

Creator:: Saldías, Gonzalo
Abstract:: 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...

Benthic biological invasions in two temperate estuaries and their effects on trophic relations of native fish and community stability

Creator:: Castillo, Gonzalo C.
Abstract:: 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...

Analysis of the benthic Cumacea and Gammaridean Amphipoda from the western Beaufort Sea

Creator:: Castillo Alarcon, Jorge Gonzalo
Abstract:: 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...

Assessment of the ecosystem services provided by urban trees in the "monumental zone" of the city of Iquitos, Loreto - Peru, 2023

Creator:: Tuesta Cartagena, Bruno Gonzalo
Abstract:: 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...

Fluctuations of year-class strength in petrale sole (Eopsetta jordani) and their relation to environmental factors

Creator:: Castillo, Gonzalo C.
Abstract:: 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...

Overfishing and No Substitution between Wild and Farmed Fish: Lessons from the European Sea Bass

Creator:: Rodríguez-Rodríguez, Gonzalo and Bande Ramudo, Roberto
Abstract:: 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...

Creator:: Parker, Kari
Abstract:: Industries such as science, technology, engineering and mathematics (STEM), continue to employ fewer women compared to men. These professions that are traditionally considered more masculine sustain gender-imbalanced work forces and are also unattractive to women at an academic level. This thesis explores the hypothesis that performance can be a powerful...

Riverine discharges impact physiological traits and carbon sources for shell carbonate in the marine intertidal mussel Perumytilus purpuratus

Creator:: Pérez, Claudia A., Lagos, Nelson A., Saldías, Gonzalo S., Waldbusser, George, and Vargas, Cristian A.
Abstract:: 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...

Inclusion of the variability of model parameters on shelf-life estimations for low and intermediate moisture vegetables

Creator:: Escobedo-Avellaneda, Zamantha, Velazquez, Gonzalo, Torres, J. Antonio, and Welti-Chanes, Jorge
Abstract:: 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...

Is Aquaculture Production Growing in Latin America and the Caribbean?

Creator:: Villasante, Sebastian and Rodriguez, Gonzalo
Abstract:: Fisheries constitute a major productive sector in Latin America and the Caribbean. This sector generates income, provides employment, and makes a significant contribution to food security and the generation of foreign exchange. With most fishery resources fully exploited or depleted, opportunities for fishery development lie primarily in restoring depleted stocks...
