Consequences of culturally-driven ecological specialization: Killer whales and beyond
by Hal Whitehead 12 Jun '26

12 Jun '26

The following paper has just been published: Consequences of culturally-driven ecological specialization: Killer whales and beyond. by: Hal Whitehead and John K.B. Ford Journal of Theoretical Biology 456: 279-294 Abstract: Culturally-transmitted ecological specialization occurs in killer whales, as well as other species. We hypothesize that some of the remarkable demographic and ecological attributes of killer whales result from this process. We formalize and model (using agent-based stochastic models parametrized using killer whale life history) the cultural evolution of specialization by social groups, in which a narrowing of niche breadth is spread and maintained in a group through social learning. We compare the demographic and ecological results of cultural specialization to those of a similar model of specialization through natural selection. We found that specialization, through either the cultural or natural selection routes, is adaptive in the short term with specialization often increasing fitness. Generalization, in contrast, is rarely adaptive. The cultural evolution of specialization can lead to increased rates of group extirpation. Specialization has little effect on group size but tends to reduce population size and resource abundance. While the two specialization processes produce similar results, cultural specialization can be very much faster. The results are generally consistent with what we know of the formation and maintenance of specialist ecotypes in killer whales, and have implications for the persistence, nature and ecological effects of these apex predators.

Update to SOCPROG
by Hal Whitehead 01 Jul '24

01 Jul '24

A new and updated version of SOCPROG, SOCPROG2.9 (both compiled and uncompiled downloads) is available at: http://whitelab.biology.dal.ca/SOCPROG/social.htm SOCPROG is a MATLAB-based package of programs for the analysis of animal social structures, movements and populations. The compiled version does not need MATLAB itself. This version is compatible with MATLAB2018b (although it will likely work well on recent and soon-to-be-released versions of MATLAB). It fixes a few bugs and adds functionality compared to previous versions (especially association complexity). Thanks Hal Whitehead, Dalhousie University, Canada

New publication: Resistance and susceptibility of dolphins to cetacean morbillivirus (Kimberley Batley)
by Kimberley Batley 17 Mar '21

17 Mar '21

Dear all, My colleagues and I are pleased to announce the publication of the following paper: Batley KC, Sandoval‐Castillo J, Kemper CM, Attard, CRM, Zanardo, N, Tomo, I, Beheregaray, LB, Möller, LM (2018). Genome-wide association study of an unusual dolphin mortality event reveals candidate genes for susceptibility and resistance to cetacean morbillivirus. Evolutionary Applications. https://doi.org/10.1111/eva.12747 Abstract: Infectious diseases are significant demographic and evolutionary drivers of populations, but studies about the genetic basis of disease resistance and susceptibility are scarce in wildlife populations. Cetacean morbillivirus (CeMV) is a highly contagious disease that is increasing in both geographic distribution and incidence, causing unusual mortality events (UME) and killing tens of thousands of individuals across multiple cetacean species worldwide since the late 1980’s. The largest CeMV outbreak in the Southern Hemisphere reported to date occurred in Australia in 2013, where it was a major factor in a UME, killing mainly young Indo-Pacific bottlenose dolphins (Tursiops aduncus). Using cases (non-survivors) and controls (putative survivors) from the most affected population, we carried out a genome-wide association study to identify candidate genes for resistance and susceptibility to CeMV. The genomic dataset consisted of 278,147,988 sequence reads and 35,493 high quality SNPs genotyped across 38 individuals. Association analyses found highly significant differences in allele and genotype frequencies amongst cases and controls at 65 SNPs, and Random Forests conservatively identified eight as candidates. Annotation of these SNPs identified five candidate genes (MAPK8, FBXW11, INADL, ANK3, and ACOX3) with functions associated with stress, pain and immune responses. Our findings provide the first insights into the genetic basis of host defence to this highly contagious disease, enabling the development of an applied evolutionary framework to monitor CeMV resistance across cetacean species. Biomarkers could now be established to assess potential risk factors associated with these genes in other CeMV affected cetacean populations and species. These results could also possibly aid in the advancement of vaccines against morbilliviruses.

New Publication: Sarcocystis neurona in sea otters
by Tristan Burgess 29 Feb '20

29 Feb '20

My colleagues and I are pleased to announce the publication of the following OPEN ACCESS paper in Nature Scientific Reports: Burgess, T.L., Tinker, M.T., Miller, M.A. et al. Spatial epidemiological patterns suggest mechanisms of land-sea transmission for Sarcocystis neurona in a coastal marine mammal. Sci Rep 10, 3683 (2020). https://doi.org/10.1038/s41598-020-60254-5 <https://doi.org/10.1038/s41598-020-60254-5> Abstract Sarcocystis neurona was recognised as an important cause of mortality in southern sea otters (Enhydra lutris nereis) after an outbreak in April 2004 and has since been detected in many marine mammal species in the Northeast Pacific Ocean. Risk of S. neurona exposure in sea otters is associated with consumption of clams and soft-sediment prey and is temporally associated with runoff events. We examined the spatial distribution of S. neurona exposure risk based on serum antibody testing and assessed risk factors for exposure in animals from California, Washington, British Columbia and Alaska. Significant spatial clustering of seropositive animals was observed in California and Washington, compared with British Columbia and Alaska. Adult males were at greatest risk for exposure to S. neurona, and there were strong associations with terrestrial features (wetlands, cropland, high human housing-unit density). In California, habitats containing soft sediment exhibited greater risk than hard substrate or kelp beds. Consuming a diet rich in clams was also associated with increased exposure risk. These findings suggest a transmission pathway analogous to that described for Toxoplasma gondii, with infectious stages traveling in freshwater runoff and being concentrated in particular locations by marine habitat features, ocean physical processes, and invertebrate bioconcentration. -- Tristan Burgess BVSc, PhD Principal Scientist Acadia Wildlife Services <http://www.acadiawildlifeservices.com/> P.O.

new publication on using satellite AIS to analyze vessel speeds off Washington state
by Ellen M Hines 28 Feb '20

28 Feb '20

Greetings all, we are pleased to share our new open access publication: https://doi.org/10.3389/fmars.2020.00109 Using Satellite AIS to Analyze Vessel Speeds Off the Coast of Washington State, U.S., as a Risk Analysis for Cetacean-Vessel Collisions Nathan C. Greig1,2,3, Ellen M. Hines<https://www.frontiersin.org/people/u/189865>1,2*, Samantha Cope<https://www.frontiersin.org/people/u/761066>1,4 and XiaoHang Liu2 * 1Estuary & Ocean Science Center, San Francisco State University, Tiburon, CA, United States * 2Department of Geography & Environment, San Francisco State University, San Francisco, CA, United States * 3Midpeninsula Regional Open Space District, Los Altos, CA, United States * 4ProtectedSeas, Anthropocene Institute, Palo Alto, CA, United States Most species of whales are vulnerable to vessel collisions, and the probability of lethality increases logistically with vessel speed. An Automatic Identification System (AIS) can provide valuable vessel activity data, but terrestrial-based AIS has a limited spatial range. As the need for open ocean monitoring increases, AIS broadcasts relayed over earth-orbiting satellites, satellite AIS (SAIS), provides a method for expanding the range of AIS broadcast reception. We used SAIS data from 2013 and 2014 to calculate vessel density and speed over ground around the coast of Washington state in the northwestern United States. Nearby shipping lanes connecting the Ports of Seattle, Tacoma, Portland, and in Canada, Vancouver, have the greatest density of vessel traffic arriving and departing. Knowledge of shipping activity is important in this area due to the nearby presence of NOAA designated Cetacean Density and Distribution Working Group's Biologically Important Areas (BIA) for large whale species vulnerable to vessel collisions. We quantified density and speed for each vessel type that transits through BIA's. We found that cargo and tanker vessels traveled the farthest distance at the greatest speeds. As ship-strike risk assessments have traditionally relied on terrestrial AIS, we explored issues in the application of SAIS data. Temporal gaps in SAIS data led to a resulting systematic underestimation of vessel speed in calculated speed over ground. However, SAIS can be helpful in documenting minimum vessel speeds across large geographic areas and across national boundaries, especially beyond the reach of terrestrial AIS receivers. SAIS data can also be useful in examining vessel density at broad scales and could be used to assess basin-wide open ocean routes. Future use of additional satellite platforms with AIS receivers and technological advances will help rectify this issue and improve data coverage and quality.

Two new papers on wild marine mammal welfare
by Laetitia Nunny 28 Feb '20

28 Feb '20

Dear colleagues, We would like to bring your attention to two open-access papers that have just been published in the area of wild marine mammal welfare, a topic which has had relatively little attention in the past. “Anthropogenic Threats to Wild Cetacean Welfare and a Tool to Inform Policy in This Area” by Christine Nicol, Lars Bejder, Laura Green, Craig Johnson, Linda Keeling, Dawn Noren, Julie Van der Hoop and Mark Simmonds considers how welfare may be scientifically assessed. It is available from Frontiers: https://www.frontiersin.org/articles/10.3389/fvets.2020.00057/full <https://www.frontiersin.org/articles/10.3389/fvets.2020.00057/full> ABSTRACT Human activities and anthropogenic environmental changes are having a profound effect on biodiversity and the sustainability and health of many populations and species of wild mammals. There has been less attention devoted to the impact of human activities on the welfare of individual wild mammals, although ethical reasoning suggests that the welfare of an individual is important regardless of species abundance or population health. There is growing interest in developing methodologies and frameworks that could be used to obtain an overview of anthropogenic threats to animal welfare. This paper shows the steps taken to develop a functional welfare assessment tool for wild cetaceans (WATWC) via an iterative process involving input from a wide range of experts and stakeholders. Animal welfare is a multidimensional concept, and the WATWC presented made use of the Five Domains model of animal welfare to ensure that all areas of potential welfare impact were considered. A pilot version of the tool was tested and then refined to improve functionality. We demonstrated that the refined version of the WATWC was useful to assess real-world impacts of human activity on Southern Resident killer whales. There was close within-scenario agreement between assessors as well as between-scenario differentiation of overall welfare impact. The current article discusses the challenges raised by assessing welfare in scenarios where objective data on cetacean behavioral and physiological responses are sparse and proposes that the WATWC approach has value in identifying important information gaps and in contributing to policy decisions relating to human impacts on whales, dolphins, and porpoises. “Animal Welfare in Predator Control: Lessons from Land and Sea. How the management of terrestrial and marine mammals impacts wild animal welfare in human-wildlife conflict scenarios in Europe” by Laetitia Nunny argues for a better approach to measure the effectiveness and welfare impacts of predator control methods. It can be found in a special edition of the journal Animals entitled “Welfare of Wild Vertebrates": https://www.mdpi.com/2076-2615/10/2/218 <https://www.mdpi.com/2076-2615/10/2/218> ABSTRACT The control of predators, on land and in the sea, is a complex topic. Both marine and terrestrial mammal predators come into conflict with humans in Europe in many ways and yet their situations are rarely compared. Areas of conflict include the predation of livestock and farmed fish, and the perceived competition for wild prey (for example wolves competing with hunters for deer and seals competing with fishermen for salmon). A lethal method (shooting) and non-lethal methods of conflict reduction (including enclosures, guarding, and aversion) used for terrestrial large carnivores (e.g., bear, wolf, wolverine, lynx) and marine mammals (seals) are discussed. Control measures tend to be species- and habitat-specific, although shooting is a widely used method. Potential impacts on predator welfare are described and welfare assessments which have been developed for other wildlife control scenarios, e.g., control of introduced species, are considered for their potential use in assessing predator control. Such assessments should be applied before control methods are chosen so that decisions prioritizing animal welfare can be made. Further work needs to be carried out to achieve appropriate and widely-accepted animal welfare assessment approaches and these should be included in predator management planning. Future research should include further sharing of approaches and information between terrestrial and marine specialists to help ensure that animal welfare is prioritized. We hope you find these articles interesting and useful.
