Inferring cetacean population densities from the absolute dynamic topography of the ocean in a hierarchical Bayesian framework.

Autor: Mario A Pardo, Tim Gerrodette, Emilio Beier, Diane Gendron, Karin A Forney, Susan J Chivers, Jay Barlow, Daniel M Palacios

Publikováno v: PLoS ONE, Vol 10, Iss 3, p e0120727 (2015)

We inferred the population densities of blue whales (Balaenoptera musculus) and short-beaked common dolphins (Delphinus delphis) in the Northeast Pacific Ocean as functions of the water-column's physical structure by implementing hierarchical models

Blubber cortisol: a potential tool for assessing stress response in free-ranging dolphins without effects due to sampling.

Autor: Nicholas M Kellar, Krista N Catelani, Michelle N Robbins, Marisa L Trego, Camryn D Allen, Kerri Danil, Susan J Chivers

Publikováno v: PLoS ONE, Vol 10, Iss 2, p e0115257 (2015)

When paired with dart biopsying, quantifying cortisol in blubber tissue may provide an index of relative stress levels (i.e., activation of the hypothalamus-pituitary-adrenal axis) in free-ranging cetacean populations while minimizing the effects of

Age estimates for female eastern and whitebelly spinner dolphins (Stenella longirostris) incidentally killed in the eastern tropical Pacific tuna purse-seine fishery from 1973-82

Autor: Susan J. Chivers, Jason P. Larese

Publikováno v: J. Cetacean Res. Manage.. 10:169-177

Age was estimated from teeth for 1,267 female eastern spinner dolphins (Stenella longirostris orientalis) and 1,071 female whitebelly spinner dolphins (S. longirostris) incidentally killed in the eastern tropical Pacific yellowfin tuna purse-seine fi

Cetacean strandings in San Diego County, California, USA: 1851–2008

Autor: Kerri Danil, Susan J. Chivers, Mike D. Henshaw, Janet L. Thieleking, Risa Daniels, Judy A. St. Leger

Publikováno v: J. Cetacean Res. Manage.. 11:163-184

There were 717 cetacean strandings recorded in San Diego County, California, USA between 1851 and 2008. These strandings comprised 18 odontocete and 6 mysticete species. Common dolphins (both the short-beaked (Delphinus delphis) and long-beaked commo

Cooperative feeding in common dolphins as suggested by ontogenetic patterns in δ 15 N bulk and amino acids

Autor: Tim Gerrodette, Kerri Danil, Rocio I. Ruiz-Cooley, Susan J. Chivers

Publikováno v: Journal of Animal Ecology. 90:1583-1595

Understanding the effect of stage-specific traits on species feeding habits can reveal how natural selection shapes life strategies. Amino acid (AA) nitrogen stable isotopes (δ15 N) provide multiple proxies of habitat baseline values and diet that c

Fidelity to natal social groups and mating within and between social groups in an endangered false killer whale population

Autor: Barbara L. Taylor, Karen K. Martien, Antoinette M. Gorgone, Susan J. Chivers, Sabre D. Mahaffy, Robin W. Baird

Publikováno v: Endangered Species Research, Vol 40, Pp 219-230 (2019)

Most mammals exhibit natal dispersal of one or both sexes, a behavior that likely evolved in part to reduce the chances of breeding with close relatives. When natal social group fidelity of both sexes has been documented, the risk of inbreeding is re

Moving Towards Dynamic Ocean Management: How Well Do Modeled Ocean Products Predict Species Distributions?

Autor: Elizabeth A. Becker, Karin A. Forney, Paul C. Fiedler, Jay Barlow, Susan J. Chivers, Christopher A. Edwards, Andrew M. Moore, Jessica V. Redfern

Publikováno v: Remote Sensing, Vol 8, Iss 2, p 149 (2016)

Species distribution models are now widely used in conservation and management to predict suitable habitat for protected marine species. The primary sources of dynamic habitat data have been in situ and remotely sensed oceanic variables (both are con
