Understanding the rich social lives of animals benefits international conservation efforts
Blue whale songs provide a measure for characterising worldwide blue population structure. These are divided into nine regional types, which maintain stable character. Five of the song types have been recorded over time spans greater than 30 years showing no significant change in The can be those containing only simple tonal components (high latitude North Pacific, Atlantic and Southern Ocean types), comprised complex pulsed units addition to (Pacific margin from California, Chile New...
A key goal of conservation is to protect biodiversity by supporting the long-term persistence viable, natural populations wild species. Conservation practice has long been guided genetic, ecological and demographic indicators risk. Emerging evidence animal culture across diverse taxa its role as a driver evolutionary diversification, population structure processes may be essential for augmenting these conventional approaches decision-making. Animal was focus ground-breaking resolution under...
The role of behavioral ecology in improving wildlife conservation and management has been the subject much recent debate. We sought to answer 2 foundational questions about current use knowledge conservation: To what extent is used management, how does animal behavior differ among fields both frequency types use? searched literature for intersections between key created a systematic heat map (i.e., graphical representation data where values are represented as colors) visualize relative...
[Adult female mortality of northern elephant seals, Mirounga angustirostris, was monitored daily throughout the breeding season and weekly during non-breeding at Ano Nuevo, California, period 1968 to 1987. Behavioral observation necropsy findings were collected circumstantial evidence compiled determine cause death. Female deaths on rookery rare; only 17 recorded over 20 year period. Cause death could not be estimated in three cases because advanced decomposition, one died from an accident,...
A bstract In October 1997 we observed a herd of approximately 35 killer whales ( Orcinus orca ) attack pod nine sperm Physeter macrocephalus 130 km off the coast central California. During four hours watched, adult female whales, including some with calves, attacked in waves to five animals what was apparently “wound and withdraw” strategy. Adult male stood by until very end when one charged quickly killed seriously wounded whale that had been separated from group. The appeared largely...
Abstract The mechanisms that determine population structure in highly mobile marine species are poorly understood, but useful towards understanding the evolution of diversity, and essential for effective conservation management. In this study, we compare putative sperm whale populations located Gulf Mexico, western North Atlantic, Mediterranean Sea using mtDNA control region sequence data 16 polymorphic microsatellite loci. Atlantic each possessed similar low levels haplotype nucleotide...

Many severely depleted populations of baleen whales (Mysticeti) have exhibited clear signs recovery whereas there are few examples in toothed (Odontoceti). We hypothesize that this difference is due, at least part, to social and behavioural factors. Clearly, a part the lack resilience exploitation explained by odontocete life history. However, an additional factor may be highly nature many odontocetes which survival reproductive success depend on: (a) cohesion organization, (b) mutual...
Mating with multiple partners is common across species, and understanding how individual males secure fertilization in the face of competition remains a fundamental goal evolutionary biology. Game theory stipulates that have fixed budget for reproduction can lead to trade-off between investment precopulatory traits such as body size, armaments, ornaments, postcopulatory testis size spermatogenic efficiency. Recent theoretical empirical studies shown if monopolize access females, they will...
The interplay of natural selection and genetic drift, influenced by geographic isolation, mating systems population size, determines patterns diversity within species. sperm whale provides an interesting example a long-lived species with few barriers to dispersal. Worldwide mtDNA is relatively low, but highly structured among regions social groups, attributed female philopatry. However, it unclear whether this philopatry due or how might vary on worldwide scale. To answer these questions, we...
Abstract We use mitochondrial DNA (mtDNA) (400 bp), six microsatellites and 36 single‐nucleotide polymorphisms (SNPs), 20 of which were linked, to investigate population structure sperm whales ( Physeter macrocephalus ) in the eastern central North Pacific. SNP markers, reproducible across technologies laboratories, are ideal for long‐term studies globally distributed species such as whales, a conservation concern because both historical contemporary impacts. estimate genetic differentiation...
Abstract Taxonomy is an imprecise science that delimits the evolutionary continuum into discrete categories. For marine mammals, this complicated by relative lack of morphological data for taxa inhabit remote and often vast ranges. We provide guidelines to promote consistency in studies relying primarily on molecular genetic delimit cetacean subspecies from both populations species. These identify informational needs: basis taxonomic hypothesis being tested, description current taxonomy,...
Acoustic communication is an important aspect of reproductive, foraging and social behaviours for many marine species. Northeast Pacific blue whales ( Balaenoptera musculus ) produce three different call types—A, B D calls. All may be produced as singular calls, but A calls also occur in phrases to form songs. To evaluate the behavioural context phrase production whales, acoustic dive profile data from tags deployed on individuals off southern California were assessed using generalized...
Abstract Sequence polymorphism of homologues ZFX and ZFY, in a 604‐base pair exon region, was examined 10 known males females across seven cetacean families used to design simple, highly sensitive widely applicable fluorescent 5′ exonuclease assay for gender determination cetaceans. Multiplex amplification, cloning, sequencing these previously uncharacterized regions revealed (i) eight fixed differences between (ii) 29 variable sites ZFY (iii) very low interspecific nucleotide diversity both...
[During mating attempts by males, female elaphant seals, Mirounga angustirostris, are sometimes injured or killed as they return to sea at the end of lactation. We tested two predictions from general hypothesis that females behave in a way reduces possibility injury death sexual encounters with males: 1) departing attempt avoid and 2) if males cannot be avoided, exhibit sexually receptive behavior thereby reduce threat aggressive attempts.

Pinnipeds vary in adult pelage color and pattern ranging from uniform white to black or brown solid coloration subtle spotted bold markings. Moreover, often differs by sex age with neonates having radically different patterning those of adults. We explored the functional significance these patterns 34 species pinniped using comparative phylogenetic analyses. found strong evidence support hypothesis background matching on land because which adults pups have live Arctic regions are subject...
Fishing, farming and ranching provide opportunities for predators to prey on resources concentrated by humans, a behavior termed depredation. In the Gulf of Alaska, observations sperm whales depredating fish caught demersal longline gear dates back 1970s, with reported incidents increasing in mid-1990s. Sperm whale depredation provides an opportunity study spread novel foraging within population. Data were collected during National Marine Fisheries Service surveys using waters off Alaska...
