Mortality and injuries caused by ship strikes in U.S. waters are a cause of concern for the endangered population of blue whales (Balaenoptera musculus) occupying the eastern North Pacific.

The thermal structure of convergent margins provides information related to the tectonics, geodynamics,
metamorphism, and fluid flow of active plate boundaries. We report 176 heat flow measurements
made with a violin bow style probe across the Costa Rican margin at the Middle America Trench. The
probe measurements are collocated with...
Past tracking studies of marine animals have primarily targeted adults, biasing our understanding of at-sea habitat use toward older life stages. Anthropogenic threats persist throughout the at-sea ranges of all life stages and it is therefore of interest to population ecologists and managers alike to understand spatiotemporal distributions and possible...
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants generated as byproducts of natural and anthropogenic combustion processes. Despite significant public health concern, physiologically based pharmacokinetic (PBPK) modeling efforts for PAHs have so far been limited to naphthalene, plus simpler PK models for pyrene, nitropyrene, and benzo[a]pyrene (B[a]P). The dearth of...
The effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposure on hepatic
pyruvate carboxylase (PC) gene expression were investigated in C57BL/6J Ah[superscipt b/b male
mice. A dose-dependent reduction of PC levels and activity occurred in animals given a
single intraperitoneal dose of TCDD in a corn oil carrier. The dose ranged from 1 to...
The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...
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...
