The marine climate of the Galapagos is spatially and seasonally
heterogeneous. A taxonomically comprehensive study of Galapagos zooplankton has
never been done. This study is an initial effort to establish the distribution and
community structure of zooplankton in the Archipelago. I collected zooplankton
samples by vertical tows over the Galapagos...
Aquatic animals are exposed to a variety of natural and
anthropogenic xenobiotics. Biotransformation of xenobiotics was
examined in three aquatic animals: a primitive mollusc (chiton);
a shellfish which is an important human food source (oyster);
and, a lower vertebrate model for toxicological studies (rainbow
trout). Since digestive glands of Cryntochiton...
Bermeo is a small town in the north of the Iberian Peninsula, cradle of a purse seiner of undisputed global relevance. Since the time of the Romans, it was recognized for its port, which led it to be one of the first three villages that were founded in the former...
The purpose of this thesis is to understand the experiences that Nahua children, in rural Mexico, have as they attend schools that are primarily influenced by formal Western education in relation to their own ways of learning and knowing. This research took place over the course of three months within...
Studies of anthropogenic impacts on wildlife may produce inconclusive or biased results if they
fail to account for natural sources of variation in breeding performance and do not use probabilistic sampling
at a scale functional for management. We used stratified random sampling and generalized linear mixed
models to test hypotheses...

Grassland and shrubland birds are declining globally due in part to anthropogenic habitat modification. Because population performance of these species is also influenced by non-anthropogenic factors, it is important to incorporate all relevant ecological drivers into demographic models. We used design-based sampling and occupancy models to test relationships of environmental...

The purpose of this study was to understand the vulnerability and adaptive capacity of shellfish stakeholders in the Pacific Northwest who are adapting to ocean acidification (OA). This study developed a geovisualization tool of existing environmental data for assessing species-specific risk profiles to OA (based on their exposure and sensitivity),...
High vegetative growth of Pinot Noir vine is a common problem in most vineyards of Oregon's Willamette Valley, where sunlight exposure and heat accumulation are limited. Consequently, growers in this region commonly use vineyard management strategies to regulate vine vigor and improve grape and wine quality. Wine quality is greatly...
Winegrapes are an important crop for Oregon agriculture, ranking amongst the top ten agricultural commodities based on farmgate value. The most widely planted winegrape cultivar in the state is ‘Pinot noir’ (Vitis vinifera L.), and the majority of acreage is produced in the Willamette Valley. Production of quality ‘Pinot noir’...
Knowledge of the mean recharge elevation (MRE) of water resources is
important for informing conservation and protection practices where water security is threatened by population growth, urban expansion, and land and climate changes. In this study a Bayesian approach was developed and applied to determine the MRE of 682 surface...
