Accurately estimating the risk of sensitive populations subjected to toxicant disturbances is central to our ability to protect ecosystem services. While the gold standard for assessing risk historically involves static measures such as the LD50 or LC50, more sophisticated approaches have been developed in an attempt to capture more nuanced outcome...
Bycatch remains a major challenge in commercial fisheries, with large numbers of threatened species impacted by incidental capture. One of the most vulnerable bycatch groups in global tuna fisheries are the manta and devil rays (mobulids), which have experienced significant population declines in response to both targeted and incidental capture. Th...
Source-based writing exists at the intersection of information literacy and written communication, where information from sources is incorporated into writing to achieve a communicative purpose. This case study addresses how students in junior-level college writing classes use information from sources in their papers and how they think about these ...
Ontogenetic changes in area use, habitat use, and trophic interactions play an important role in the ecology, demography, and ultimately population dynamics of many species. Assumed to be driven by shifting life-history requirements, trophic niche shifts in white sharks (Carcharodon carcharias) are well documented, but the timing of the spatial nic...
State-level cooperative extension services provide fertilizer recommendations for row crops in the United States. Of these, nitrogen (N) recommendations are arguably the most important because N is the most common yield-limiting nutrient in nonlegume crop production systems. Throughout the peanut (Arachis hypogaea L.) growing region of the United S...
Environmental DNA (eDNA) sampling from rivers has emerged as a promising new method for monitoring freshwater organisms of management concern. However, eDNA sampling cannot yet offer reliable estimates of a target species' abundance/biomass or confident determinations of a species' absence from a river segment. To unlock these abilities—and thereby...
An overview of how macroeconomic shocks affect beef quality-grade premiums and discounts in the U.S. fed cattle market is discussed. We review the shock transmission linkages along the beef industry supply chain and determine the economic implications for the finished cattle market. The analysis provides insight into how the fed cattle market respo...
The almond industry in California faces water management challenges that are being exacerbated by droughts, climate change, and groundwater sustainability legislation. The Tree-crop Remote sensing of Evapotranspiration eXperiment (T-REX) aims to explore opportunities to improve precision irrigation management for woody perennial cropping systems. A...
The red alga, Pyropia perforata, commonly referred to as nori, is ubiquitous in intertidal communities throughout coastal California and offers high nutritional value to marine herbivores. However, California rocky shores are dynamic ecosystems, with dramatic abiotic and biotic shifts resulting in environmental heterogeneity. Research has shown tha...
Understanding the spatial ecology of highly migratory marine animals is essential for effective conservation strategies, particularly in the face of climate change and increasing anthropogenic pressures. This study investigates the nesting characteristics, habitat use, and behavior of leatherback sea turtles (Dermochelys coriacea) in the Northwest ...
