Prey-mediated behavioral responses of feeding blue whales in controlled sound exposure experiments

Creator:: Friedlaender, A. S., Hazen, E. L., Goldbogen, J. A., Stimpert, A. K., Calambokidis, J., and Southall, B. L.
Abstract:: 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...

Evidence for acoustic communication among bottom foraging humpback whales

Creator:: Parks, Susan E., Cusano, Dana A., Stimpert, Alison K., Weinrich, Mason T., Friedlaender, Ari S., and Wiley, David N.
Abstract:: Humpback whales (Megaptera novaeangliae), a mysticete with a cosmopolitan distribution, demonstrate marked behavioural plasticity. Recent studies show evidence of social learning in the transmission of specific population level traits ranging from complex singing to stereotyped prey capturing behaviour. Humpback whales have been observed to employ group foraging techniques, however details...

Prey density and distribution drive the three-dimensional foraging strategies of the largest filter feeder

Creator:: Goldbogen, Jeremy A., Hazen, Elliott L., Friedlaender, Ari S., Calambokidis, John, DeRuiter, Stacy L., Stimpert, Alison K., and Southall, Brandon L.
Abstract:: 1. Despite their importance in determining the rate of both energy gain and expenditure, how the fine-scale kinematics of foraging are modified in response to changes in prey abundance and distribution remain poorly understood in many animal ecosystems. 2. In the marine environment, bulk-filter feeders rely on dense aggregations of...

Acoustic and foraging behavior of a Baird’s beaked whale, Berardius bairdii, exposed to simulated sonar

Creator:: Stimpert, A. K., DeRuiter, S. L., Southall, B. L., Moretti, D. J., Falcone, E. A., Goldbogen, J. A., Friedlaender, A. S., Schorr, G. S., and Calambokidis, John
Abstract:: 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...

Using accelerometers to determine the calling behavior of tagged baleen whales

Creator:: Goldbogen, J. A., Stimpert, A. K., DeRuiter, S. L., Calambokidis, J., Friedlaender, A. S., Schorr, G. S., Moretti, D. J., Tyack, P. L., and Southall, B. L.
Abstract:: 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...

Fingered Flow in Two Dimensions 2. Predicting Finger Moisture Profile

Creator:: Selker, J., Parlange, J.-Y., and Steenhuis, T.
Abstract:: An exact integral solution for the moisture profile in growing fingers in sandy soil is derived from Richards' equation. The solution provides moisture content along a finger as a function of position and time and provides applicable results, including the calculation of the asymptotic matric potential of a growing finger...

Multiple-stage decisions in a marine central-place forager

Creator:: Friedlaender, Ari S., Johnston, David W., Tyson, Reny B., Kaltenberg, Amanda, Goldbogen, Jeremy A., Stimpert, Alison K., Curtice, Corrie, Hazen, Elliott L., Halpin, Patrick N., Read, Andrew J., and Nowacek, Douglas P.
Abstract:: 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...

ARK: Aggregation of Reads by K-Means for Estimation of Bacterial Community Composition

Creator:: Koslicki, David, Chatterjee, Saikat, Shahrivar, Damon, Walker, Alan W., Francis, Suzanna C., Fraser, Louise J., Vehkaperä, Mikko, Lan, Yueheng, and Corander, Jukka
Abstract:: Motivation: Estimation of bacterial community composition from high-throughput sequenced 16S rRNA gene amplicons is a key task in microbial ecology. Since the sequence data from each sample typically consist of a large number of reads and are adversely impacted by different levels of biological and technical noise, accurate analysis of...

A Highly Fatigue-Resistant Zr-Based Bulk Metallic Glass

Creator:: Naleway, Steven E., Greene, Rawley B., Gludovatz, Bernd, Dave, Neil K. N., Ritchie, Robert O., and Kruzic, Jamie J.
Abstract:: The strength-normalized fatigue endurance strength of the bulk metallic glass (BMG) Zr₅₂.₅Cu₁₇.₉Ni₁₄.₆Al₁₀Ti₅ (Vitreloy 105) has been reported to be the highest for any BMG; however, to date, there has been no explanation of why this material is so much better than other Zr-based compositions. In this study, the fatigue-crack growth...
