161.  Variation in individual reproductive performance amplified with population size in a long-lived carnivore.LinkIT
Badger JJ, Bowen WD, den Heyer CE, Breed GA
EcologyEcologyVariation in individual reproductive performance amplified with population size in a long-lived carnivore.e0302410.1002/ecy.3024Individual variation in reproductive ability is a key component of natural selection within populations, driving the evolution of life histories and population responses to changing environmental conditions. Evidence that population density affects individual-level fitness in wild populations is limited, particularly for long-lived animals, which are difficult to observe on a biologically relevant scale. We tested for individual heterogeneity in reproductive performance in female grey seals (Halichoerus grypus) using 35 yr of mark-resighting data at Sable Island, Canada (43.93° N 59.91° W). We used Bayesian generalized linear mixed-effect models and multistate open robust design mark-resight models to investigate whether population size negatively influences individual reproductive performance. We measured reproductive performance in two ways: reproductive frequency (the probability of returning to the island to breed) and annual provisioning performance (the probability of successfully weaning a pup given a female bred). Sighting histories of 1,655 known-aged females with a total of 22,961 pupping events were used for analysis. After accounting for effects of female age, parity, and random year effects, we found that both provisioning performance and reproductive frequency demonstrated a strong, positive correlation with population size. Among-individual variance in reproductive traits and responses to population size indicated considerable heterogeneity in overall reproductive performance. As population size grew, "robust" females increased their reproductive performance more than their more "frail" conspecifics in both reproductive traits, resulting in an amplification of differences among individuals. Consequently, simulations from posterior distributions revealed a large fitness consequence of heterogeneity in this population, with "frail" individuals having 47.1% fewer successful pups than more "robust" females (mean reproductive output ± SD: 9.12 ± 3.77 pups for frail individuals, 16.97 ± 2.94 for robust individuals). Repeatability of overall reproductive performance across environments indicates individual quality may be more influential to lifetime reproductive success than costs associated with reproductive investment. This quantification of relative fitness and its dynamics is crucial to understanding broad evolutionary processes in natural populations.© 2020 by the Ecological Society of America.BadgerJanelle JJJ0000-0001-5927-7301Department of Biolog y and Wildlife, University of Alaska Fairbanks, Fairbanks, Alaska, 756100, USA.BowenW DonWDDepartment of Fisheries and Oceans Canada, Bedford Institute of Oceanography, 1 Challenger Dr, Dartmouth, Nova Scotia, Canada.den HeyerCornelia ECEDepartment of Fisheries and Oceans Canada, Bedford Institute of Oceanography, 1 Challenger Dr, Dartmouth, Nova Scotia, Canada.BreedGreg AGADepartment of Biolog y and Wildlife, University of Alaska Fairbanks, Fairbanks, Alaska, 756100, USA.Institute of Arctic Biology, University of Alaska Fairbanks, Fairbanks, Alaska, 757000, USA.engNatural Sciences and Engineering Research Council of CanadaInternational1839290National Science Foundation Graduate Research FellowshipInternationalJournal ArticleResearch Support, Non-U.S. Gov'tResearch Support, U.S. Gov't, Non-P.H.S.20200417United StatesEcology00435410012-9658IMAnimalsBayes TheoremCanadaFemaleHumansPopulation DensityReproductionSeals, EarlessHalichoerus grypusBayesian statisticsgrey sealindividual heterogeneitylife history theorymark-resightpinnipedsqualityreproductive performance20190722201912122020012220202236020211760202022260ppublish3208373510.1002/ecy.3024Literature Cited, 2020</i></font><br><font color=#008000>http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0<br></font></span><br>162.  <a href=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0 class=title>Fur and faeces - Routes of mercury elimination in the Baltic grey seal (Halichoerus grypus grypus).</a><a href=http://ubio.org/tools/linkit.php?map%5B%5D=all&link_type=2&url=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0><img src=linkit.png border=0 title='LinkIT' alt='LinkIT'></a> <br><span class=j>Grajewska A, Falkowska L, Saniewska D, Pawliczka I<br><font color=gray><i>The Science of the total environment, 2020</i></font><br><font color=#008000>http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0<br></font></span><br>163.  <a href=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0 class=title>Polychlorinated Biphenyls (PCBs) and Sex Hormone Concentrations in Ringed and Grey Seals: A Possible Link to Endocrine Disruption?</a><a href=http://ubio.org/tools/linkit.php?map%5B%5D=all&link_type=2&url=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0><img src=linkit.png border=0 title='LinkIT' alt='LinkIT'></a> <br><span class=j>Troisi GM, Barton SJ, Liori O, Nyman M<br><font color=gray><i>Archives of environmental contamination and toxicology, 2020</i></font><br><font color=#008000>http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0<br></font></span><br>164.  <a href=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0 class=title>Pinnipeds orient and control their whiskers: a study on Pacific walrus, California sea lion and Harbor seal.</a><a href=http://ubio.org/tools/linkit.php?map%5B%5D=all&link_type=2&url=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=0><img src=linkit.png border=0 title='LinkIT' alt='LinkIT'></a> <br><span class=j>Milne AO, Smith C, Orton LD, Sullivan MS, Grant RA<br><font color=gray><i>Journal of comparative physiology.
