A dynamic approach to estimate the probability of exposure of marine predators to oil exploration seismic surveys over continental shelf waters

Autor: Hückstädt, LA, Schwarz, LK, Friedlaender, AS, Mate, BR, Zerbini, AN, Kennedy, A, Robbins, J, Gales, NJ, Costa, DP

Publikováno v: Endangered Species Research, Vol 42, Pp 185-199 (2020)

The ever-increasing human demand for fossil fuels has resulted in the expansion of oil exploration efforts to waters over the continental shelf. These waters are largely utilized by a complex biological community. Large baleen whales, in particular,

East or west: the energetic cost of being a gray whale and the consequence of losing energy to disturbance

Autor: Villegas-Amtmann, S, Schwarz, LK, Gailey, G, Sychenko, O, Costa, DP

Publikováno v: Endangered Species Research, Vol 34, Pp 167-183 (2017)

Western gray whales (WGW) Eschrichtius robustus are considered one of the world’s most endangered baleen whale populations. Development of oil and gas fields in northeastern Sakhalin, Russia, is a concern, because they overlap with WGW feeding grou

Foraging strategies of a generalist marine predator inhabiting a dynamic environment

Autor: McHuron, EA, Robinson, PW, Simmons, SE, Kuhn, CE, Fowler, M, Costa, DP

Publikováno v: Oecologia, vol 182, iss 4

Intraspecific variability is increasingly recognized as an important component of foraging behavior that can have implications for both population and community dynamics. We used an individual-level approach to describe the foraging behavior of an ab

Growth and energy expenditure of Wandering Albatross Diomedea exulans chicks

Autor: Mabille, G., Boutard, O., Scott Shaffer, Costa, Dp, Weimerskirch, H.

Publikováno v: ResearcherID

Wandering Albatross Diomedea exulans chicks require 9–10 months to achieve adult body size at fledging, at which time they are also sexually size dimorphic. Because the developmental period spans the winter season, chicks must endure severe winter

1. Theoretical models predict that animals will vary their effort to maximize different currencies such as time and energy when the constraints of reproduction change during breeding, but this has been poorly studied in free-ranging animals. 2. Forag
