A major focus in macroecology is to understand the mechanisms that drive differences in habitat, morphology, and behavior in closely related species (Brown 1995). Within this paradigm, energy use and prey acquisition play a fundamental role in affecting behavior, especially with respect to foraging patterns and predator‐prey interactions. Because resources...

Air-breathing marine animals face a complex set of physical challenges associated with diving that affect the decisions of how to optimize feeding. Baleen whales (Mysticeti) have evolved bulk-filter feeding mechanisms to efficiently feed on dense prey patches. Baleen whales are central place foragers where oxygen at the surface represents the...
High early strength concrete (HESC) allows for faster construction with less impact on traffic, thus reducing the indirect costs associated with a project. There are multiple methods for achieving early strength, such as alternative cements like calcium sulfoaluminate (CSA) or chemically accelerated portland cements. The standard criteria for an HESC...
Behavioral response studies provide significant insights into the nature, magnitude, and consequences of changes in animal behavior in response to some external stimulus. Controlled exposure experiments (CEEs) to study behavioral response have faced challenges in quantifying the importance of and interaction among individual variability, exposure conditions, and environmental covariates. To...
Beaked whales are hypothesized to be particularly sensitive to anthropogenic noise, based on previous
strandings and limited experimental and observational data. However, few species have been studied in
detail. We describe the underwater behavior of a Baird’s beaked whale (Berardius bairdii) from the first
deployment of a multi-sensor acoustic tag...
Low-frequency acoustic signals generated by baleen whales can
propagate over vast distances, making the assignment of calls to
specific individuals problematic. Here, we report the novel use of
acoustic recording tags equipped with high-resolution accelerometers
to detect vibrations from the surface of two tagged fin whales that
directly match the...
In January 2008, the Georgia Water Council approved the Georgia Comprehensive State-Wide Water Management Plan (GA Water Plan). The purpose of GA Water Plan is to guide the state of Georgia with managing its water resources in a sustainable manner. This means not only allowing growth in Georgia, but also...
