The presence of foraging bears in Arctic breeding bird colonies has been increasingly reported the literature, and these may constitute disturbance events which cause incubating birds to leave their nest. Avian predators associate with during such events, likely capitalize on unattended nests bears. Here, we estimated changes daily nest attendance lesser snow geese Anser caerulescens bears, ass...

Disturbance from whale watching can induce a wide range of behavioral responses in cetaceans, some which affect their energetic balance and, ultimately, long-term fitness. However, assessing disturbance effects on deep-diving cetaceans remains challenging, as the majority activities occurs underwater and are difficult to monitor surface observations. To surpass this limitation, we attached high...

Foraging provides an integrative view of the effects environmental variability on marine predators, from direct through increased energetic costs at sea to indirect modification prey accessibility. Using a 19 yr automated monitoring system ~400 individuals (>45000 foraging trips), we investigated short-term and interannual in performance (trip duration mass gain) breeding little penguins Eud...

BACKGROUND Plastic root-foraging responses have been widely recognized as an important strategy for plants to explore heterogeneously distributed resources. However, the benefits and costs of root foraging have received little attention. METHODOLOGY/PRINCIPAL FINDINGS In a greenhouse experiment, we grew pairs of connected ramets of 22 genotypes of the stoloniferous plant Potentilla reptans in...

An essential first step in analogy is retrieval of a source analogue appropriate for the target situation. In this paper, we focus on the phenomenon of interactive analogical retrieval (IAR) wherein the source analogues are obtained through interaction with online information environments. We first provide a descriptive account of IAR based on two in situ studies. We then describe an informatio...

In this paper, we introduce a web-enabled geovisual analytics approach to leveraging Twitter in support of crisis management. The approach is implemented in a map-based, interactive web application that enables information foraging and sensemaking using “tweet” indexing and display based on place, time, and concept characteristics. In this paper, we outline the motivation for the research, revi...

The ecological and evolutionary dynamics of populations are shaped by the strategies they use to produce and use resources. However, our understanding of the interplay between the genetic, behavioral, and environmental factors driving these strategies is limited. Here, we report on a Caenorhabditis elegans-Escherichia coli (worm-bacteria) experimental system in which the worm-foraging behavior ...

-The hunting behavior, snail size selection, and time-activity patterns of nonbreeding Snail Kites (Rostrhamus sociabilis sociabilis) were studied in Guyana rice fields. Kites spent 62% of the photoperiod perching, 19% foraging, 13% in maintenance activities, and 6% flying. As the day progressed, the percentage of daylight hours spent perching increased significantly, while foraging decreased s...
