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.

River dolphin internships in the Brazilian Amazon
by Tony 08 Oct '19

08 Oct '19

RIVER DOLPHIN RESEARCH INTERNSHIPS IN BRAZIL STARTING SOON Once again, Projeto Boto is recruiting for 9-month internships in the Mamirauá Reserve, Amazon State, Brazil. We require fit, enthusiastic, hard-working fieldworkers who will carry forward our long-term study of botos (Amazon river dolphins). Due to close involvement with local communities, interns are required to have at least moderate Portuguese language skills, or to speak excellent Spanish, in addition to English. There can be no exceptions. In previous years we have received many applications from people who do not fulfil these language criteria, and this is counter-productive. Please only apply if you have the necessary skills. Projeto boto was established in 1994. To date it has hosted more than 60 interns of many different nationalities. The Project's objective is to conserve the boto, and the sympatric tucuxi, through research leading to greater understanding of the biology and ecology of these dolphins. In recent years we have also spent considerable time investigating the impacts of fisheries on these species, and especially a harpoon hunt, in which thousands of botos are killed each year for fish bait. We are seeking two people to commence work as soon as possible, and we would also like to hear from people available in mid-late 2016. Our work is centred on a floating lab/accommodation base, moored in the flooded forest. The research team comprises 3-5 people, who maintain daily observational boat-based research effort year-round. The basis of the work is the piecing together of the lives of over 600 individually recognisable dolphins, to provide publishable information on such diverse topics as growth, reproduction, habitat use, social system, seasonal movements, survival rates, causes of mortality etc. Interns are provided with free accommodation and food, and receive a small monthly stipend (approx $150 US). Transportation to the fieldsite (near the town of Tefé, Amazonas) from Manaus is provided, but interns must arrange and pay for their own transportation to Manaus. They must also have adequate medical insurance. Please do not apply unless you know that you can obtain the airfare to reach Manaus. All necessary training is provided on site. Internships offer the opportunity of a lifetime. They reward hard work and dedication with unique experiences and a chance to stand out from the crowd in subsequent applications for higher degrees and employment. Successful applicants will: be aged 21-35 speak at least moderate Portuguese or fluent Spanish, in addition to English be available for 9-12 months have completed a university degree, preferably in zoology or biology preferably have some fieldwork experience, especially in the use of photo-ID Applicants should please provide: Full CV, complete with age, nationality, linguistic skills, educational and fieldwork experience A letter explaining why you are prepared to dedicate 9 months of your life to this study. The names and email addresses of 3 referees who are familiar with you and your work. The date on which you would be available to start work in the Amazon. Send this information by email to both of the Project co-ordinators, Prof. Tony Martin (boto(a)live.co.uk) and Dr Vera da Silva (vmfdasilva(a)gmail.com) Closing date is 24 November 2015. Applications fulfilling the above criteria will be acknowledged within 4 days of the closing date, but there will be no further communication unless the applicant is short-listed. Short-listed applicants will be notified by 30 November latest.

New publication: From the pool to the sea: Applicable isotope turnover rates and diet to skin discrimination factors for bottlenose dolphins (Tursiops truncatus)
by Joan Giménez Verdugo 01 Mar '19

Dear all, We are pleased to announce the publication of the following paper in "Journal of Experimental Marine Biology and Ecology": Giménez, J., Ramírez, F., Almunia, J., Forero, M. G., de Stephanis, R. (2016) From the pool to the sea: Applicable isotope turnover rates and diet to skin discrimination factors for bottlenose dolphins (*Tursiops truncatus*). Journal of Experimental Marine Biology and Ecology 475:54-61. *Abstract:*One of the most common applications in isotopic ecology is the assessment of animal's assimilated diet through mass-balance mixing models. Its applicability relies on the use of accurate diet to tissue discrimination factors and turnover rates, which are known to vary as a function of several factors including taxon or tissue type. To date, few studies have assessed isotopic discrimination factors and turnover rates in cetacean species under controlled conditions. Previous experimental studies focused on blood, a difficult sample to obtain in the wild, or on a more appropriate tissue, the skin, but assessed in short experimental trials without arriving to the isotopic equilibrium. We carried out the longest controlled feeding experiment available (350 days) in bottlenose dolphins (*Tursiops truncatus*) in order to assess discrimination factors and turnover rates in skin. Animals' isotopic composition was first stabilized by maintaining individuals under an isotopically constant diet during 172 days. Afterwards, diet was shifted and maintained during 178 days to calculate isotopic discrimination and turnover rates. Estimates for isotopic discrimination factors were 1.01 ± 0.37‰ (mean ± sd) for *δ*13C and 1.57 ± 0.52‰ for *δ*15N. Half-life turnover rates were estimated to be 24.16 ± 8.19 days for carbon and 47.63 ± 19 days for nitrogen. This is the first time that applicable values are available to assess the diet of free ranging small cetaceans through stable isotope mixing model analysis.

Volunteer Research Assistants/Interns - Summer 2017 Florida, USA and Bimini, The Bahamas
by Kelly Melillo Sweeting 25 Feb '19

25 Feb '19

Dolphin Communication Project (DCP) - Volunteer Research Assistants/Interns - Summer 2017 Florida, USA and Bimini, The Bahamas The Dolphin Communication Project (DCP, www.dolphincommunicationproject.org) is currently seeking two interns for the summer of 2017. These internships have field and office components, both of which are mandatory, and total 9-12 weeks, depending on DCP's schedule. DCP looks at how dolphins communicate and attempts to shed more light on the meaning of their interactions. With research ongoing since 1991, our questions focus primarily on communication and behavior among dolphins. Interns will spend the field portion of this internship at our Bimini, Bahamas, research site, where we study wild Atlantic spotted and bottlenose dolphins. An abbreviated publication list is available at the end of this post. Responsibilities In the field: --Travel to and assist for approximately 6 weeks at our Bimini research site (exact dates TBD, likely beginning in late, following the office component) --Assist gathering data (general observations, photographs) during 4-6 hour/day boat excursions (weather and schedule dependent) --Complete photo-identification of dolphins from still photography and video as well as other data entry and analysis tasks --Assist with on-board and outreach education as well as web-based projects --Represent DCP in an enthusiastic, responsible, mature and respectful manner At the office: --Travel to and assist for 4-5 weeks at our Port Saint Lucie, Florida (FL) office (exact dates TBD, likely prior to field component, beginning in late May) --Process and analyze data, including, but not limited to: photo-identification of individuals from other DCP research sites, event sampling from video data for behavioral analyses, and acoustic analysis of dolphin sounds --Assist in the development and implementation of education programs for schools and the general public, as needed Requirements Successful interns must have basic computer skills and working knowledge of Microsoft Word, Excel and PowerPoint. Current enrollment in a degree-seeking program, background in science and/or animal behavior and experience on boats and/or with photo-identification are all desired, but not necessarily required. The successful candidates will be comfortable on a boat for several hours at a time in varying conditions, including extreme heat. They will also be proficient swimmers with the desire to improve snorkeling and free-diving skills. They will be able to work as a team both in a small office and in a fairly remote and isolated field setting. Good writing and public speaking skills are a must, as is attention to details. Interns must be at least 18 years of age. Although international applicants are invited to apply, all applicants should know that interns are responsible for their own daily transportation to/from the FL office and public transportation is limited in this area; therefore, all interns should have their own transportation while in FL. Expenses and Compensation This is an unpaid internship. Interns are responsible for their own transportation to Bimini and Florida. There is a $1,100.00 fee that will cover housing in the field (on-island transportation not needed). Room, board and transportation while in Florida are the responsibility of the intern. Although assistance in finding housing may be available, the ability to find suitable housing in Florida is ultimately the interns’ responsibility. We recommend all applicants complete a preliminary housing search in advance of submitting their applications. Interested applicants should review information at this link: http://dolphincommunicationproject.org/index.php/get-involved/internships. Please read this page thoroughly before applying or emailing questions . Send a completed application (downloadable and detailed at the link above) to kelly(a)dcpmail.org. Applications are due 28 February 2017. Due to field schedules, only electronic applications will be accepted. Interviews (via telephone or Skype) will be arranged for selected candidates in early March.

New Publication FUNCTIONAL SUBDIVISION OF THE VERTEBRAL COLUMN IN FOUR SOUTH AMERICAN DOLPHINS (Mastozoologia Neotropical)
by María Constanza Marchesi 31 Oct '18

31 Oct '18

Dear Colleagues, My coauthors and I are very pleased to announce the online publication of our paper in Mastozoología Neotropical entitled: FUNCTIONAL SUBDIVISION OF THE VERTEBRAL COLUMN IN FOUR SOUTH AMERICAN DOLPHINS by M.C. Marchesi, M. S. Mora, E. A. Crespo, C. Boy, R. González-José and R.N.P Goodall, doi.org/10.31687/saremMN.18.25.2.0.12 ABSTRACT. Description and functional interpretation of morphological variation in the dolphin column can be facilitated by recognizing structural units. This information offers important clues to the proportion of the column involved in the oscillation and displacement of the ukes, and how swimming style can vary among species. Thus, the morphological characterization and functional subdivision of the vertebral column is of key importance to gain insights into the locomotor performance of cetacean species occurring in di erent environ- ments. We employed traditional morphometrics to establish the functional subdivision of the vertebral column of Commerson’s dolphin (Cephalorhynchus commersonii), a coastal species, and the dusky dolphin (Lagenorhynchus obscurus), a shelf species. These species are closely related, and some of them are partially sympatric. We also compared the obtained results against information previously reported by Marchesi et al (2017) on Peale’s dolphin (Lagenorhynchus australis), a coastal species, and the hourglass dolphin (Lagenorhynchus cruciger), an oceanic species. These results bring further support to our hypothesis that coastal species have morphological traits associated with higher flexibility, whilst platform and oceanic species have features associated with higher stability in a greater proportion of their column.

Dear all, On behalf of my co-authors, I am pleased to announce the publication of the following article: “*Preliminary study of long-range transport of halogenated flame retardants using Antarctic marine mammals**”. *Oscar Aznar-Alemany, Xuefei Yang, Mariana B. Alonso, Erli Schneider Costa, João Paulo M. Torres, Olaf Malm, Damià Barcelo, Ethel Eljarrat (2019) *Science of the Total Environment* 650: 1889–1897 DOI:10.1016/j.scitotenv.2018.09.287 *Capsule abstract:* Halogenated flame retardants were in tissues of Antarctic seals proving long-range transport. Dechloranes showed similar behaviour to PBDEs, additionally they crossed the BBB (blood-brain barrier). *Abstract:* Eight PBDE congeners, three emerging brominated flame retardants, five dechloranes and eight MeO-PBDEs were monitored in tissues (muscular, adipose, brain) and fur of southern elephant seal and Antarctic fur seal of the South Shetland Islands, Antarctic Peninsula. Total PBDEs and total dechloranes concentrations ranged between n.d.–6 ng/g lw. While PBDEs were not detected in brain tissue, Dec 602 was found in brain tissue of both seal species indicating that dechloranes —with potential neurological toxicity— could cross the blood-brain barrier. Emerging brominated flame retardants were not detected in any sample and only two MeOPBDEs, which are of natural origin, were found. The presence of the detected compounds in biota from the Antarctic evidences their long-range transportation, being of special interest the detection of emerging compounds such as dechloranes. This is the first time that these contaminants have been detected in marine mammals from the Antarctic. BDE-47 concentrations were lower than previously reported for the same species, suggesting a successful effect of the existing regulation and bans on PBDEs.

New Publication: Contact call diversity in natural beluga entrapments in an Arctic estuary: Preliminary evidence of vocal signatures in wild belugas
by Valeria Vergara 31 Oct '18

31 Oct '18

Dear colleagues, We are pleased to announce our recent article in Marine Mammal Science: Contact call diversity in natural beluga entrapments in an Arctic estuary: Preliminary evidence of vocal signatures in wild belugas. DOI:10.1111/mms.12538. Authors: Valeria Vergara and Marie-Ana Mikus The paper is available in early view at https://rdcu.be/bajyx<http://em.rdcu.be/wf/click?upn=lMZy1lernSJ7apc5DgYM8WpCuIeIguihiztFymYqWyY-…> Abstract: Broadband, pulsed contact calls have been described for captive and temporarily restrained belugas, but little information exists on their usage in the wild. We examined vocal production during 14 natural beluga entrapments in a shallow channel in Cunningham Inlet, as isolation events offer ideal contexts to study contact calls. Drone footage, overhead photos, and shore-based photos confirmed the number of individuals and age composition in each entrapment. Contact calls comprised the majority (61%) of vocalizations produced by entrapped whales compared to the free-ranging herd (10%). We divided contact calls into complex (80%), those with a stereotyped, spectrographically prominent component overlapping the pulse train that characterizes all beluga contact calls, and simple (20%), those with no overlapping component. For each entrapment, we generated a catalogue of complex contact call types, totaling 87 types. Our classification was corroborated both quantitatively and by 55 naïve human judges. Occasional instances of overlapping contact calls of the same type indicated dyadic production. The number of contact call types per entrapment was strongly related to (never exceeding) the number of individuals, excluding neonates. Although this suggests a system of vocal signatures in belugas, consistent with their fission-fusion society and earlier findings, whether signature identity is encoded individually or shared with related animals remains unknown.
