Dear colleagues,
On behalf of my co-authors, we are pleased to share with you our recent publication in Marine Pollution Bulletin: "Mercury and selenium concentrations in lanugo of free-ranging California sea lions in the southern Gulf of California, Mexico" T.E. Symon, D.A. Murillo-Cisneros, C.J. Hern?ndez-Camacho, T.M. O'Hara, R.J. Taylor, C.A. Rosado-Berrios, J.P. V?zquez-Medina, T. Zenteno-Sav?n. 2023. Marine Pollution Bulletin 197(2023): 115712. https://doi.org/10.1016/j.marpolbul.2023.115712 Abstract: Total mercury ([THg]) and selenium ([TSe]) concentrations were determined in California sea lion (Zalophus californianus) lanugo from the Gulf of California in 2021 and 2022. Relationships with sex, morphometrics, and year were evaluated. Following toxicological thresholds of concern for piscivorous mammals, most pups had a [THg] < 10 ppm, one pup (2021) had a [THg] > 20 ppm, no pups had a [THg] > 30 ppm. Females had significantly higher [TSe] than males; sex did not influence [THg]. [THg] and [TSe] in 2022 were significantly higher in the general population and male cohorts compared to 2021. Significant negative correlations were observed between [THg], [TSe], and morphometrics (2021). These results indicate that, compared to other pinniped species, regional California sea lions may have a decreased likelihood of experiencing Hg-related adverse health effects. Year-related changes in element concentrations suggest continued monitoring of this population to assess pinniped, environmental, and potentially, human health.

Due to many factors, acoustic features of a species' vocalizations may differ among populations. The present study investigated both micro- and macro-geographical variation in the vocalizations of Cape fur seal females, males, and pups. Acoustic measurements were performed on calls recorded at four South African and two Namibian sites (maximum range ~ 1,000 km). Comparisons among close sites in South Africa revealed no microgeographical variation (maximum range ~ 130 km) in females' and pups' vocalizations. Barks of subadult males had different features among sites, which may be explained mostly by the context of call production. At the macro-geographical scale (South Africa vs. Namibia), all call types varied significantly among sites. Several extrinsic and intrinsic factors were suggested to drive such differences. For fe! males' and pups' calls, differences might be explained by environmental factors, whereas for males' barks, behavioral differences are the most likely explanation for acoustic differences (breeding vs. resting sites). Such investigations help understand how? acoustic communication in marine mammals is shaped by ecological drivers. https://doi.org/10.1111/mms.13084 Best regards, - - Mathilde Martin, PhD Postdoctoral researcher Communication and Cognition in Social Mammals research group Department of Evolutionary Biology and Environmental Studies University of Zurich https://www.ieu.uzh.ch/en/research/behaviour/cognition.html https://mathildemartin-research.com -------------- next part -------------- An HTML attachment was scrubbed...

Article Title: Whales for Sale: A Content Analysis of American Whale-Watching Operators? Websites Abstract: Digital media, particularly websites, have become a critical component of wildlife tourism experiences, especially during the pretour information-seeking stage. With a focus on whale watching, this study used a grounded theory approach to identify, categorize, and investigate the common themes, text, and images used on 178 whale-watching operator websites across six geographic regions in the US. The results of a content analysis suggest that operators who are predominantly small business owners focus their marketing strategies on elements of their tour offerings and operator characteristics to distinguish themselves from competitors rather than emphasizing the whales themselves, conservation actions, or educational opportunities, catering to a segment of entertainment-oriented rather than sustainability-oriented guests. Ecolabel-certified operators in the sample mentioned conservation and educational topics more, though the information provided could still use impr! ovement. We discuss implications and opportunities for the continued study of media related to whale watching and other marine wildlife tourism activities. Happy reading! Marcus B.

ALMMSN is a cooperative regional stranding network partner and works in conjunction with the National Oceanic and Atmospheric Administration?s National Marine Fisheries Service and the US Fish and Wildlife Service to respond to dolphin, whale, and manatee strandings. Our primary goal is to enhance reporting and response efforts for marine mammal strandings to ensure collection of consistent, high-quality data that are used to evaluate causes of strandings and/or death. The DISL?s mission is to become a center for transformative U.S. oceanic and coastal research and education. This intern will gain useful knowledge, skills, and experience in the fields of marine biology, marine mammalogy, and marine mammal stranding response. *Internship Dates:* 3 months (option to extend depending on funds and performance); flexible start January 2024 *Daily Duties Include:* Field stranding response, data collection, data management, participation in necropsy events, sample handling, report writing, and equipment/lab maintenance/cleaning. Intern will also have the opportunity to complete an independent research project based on relevant interests, culminating in a presentation. *Qualifications*: -- Student or recent graduate (0-2 years) of a biology/marine biology, marine science, oceanography, zoology or related program; -- Interest in marine mammal biology, physiology and anatomy; -- Interest in research; -- Valid driver?s license and clean driving record; -- 18 years or older; -- Physically fit, able to lift at least 50 lbs, drag at least 100 lbs, and a strong swimmer; -- Ability to endure unpleasant field conditions including temperatures between 30?F-100?F, rain, humidity and biting insects; -- Ability to work 35 hours per week, including weekends, nights and holidays as needed; -- Experience with scientific writing is a plus; -- Knowledge of digital SLR cameras and lenses is a plus. This internship is a paid position ($10-$12/hour) expected to work 35 hrs/week (including nights and holidays as necessary for fieldwork). This is a physically demanding position that may involve long days in a variety of weather conditions. Intern is responsible for providing their own housing and transport to DISL. Assistance finding housing can be provided. Applicant must be eligible to legally reside in the U.S. for the duration of the internship period. International applicants are welcome to apply, however, we are unable to sponsor or take over the sponsorship of an employment VISA. All applicants must be authorized to work in the U.S. Interested applicants must send a cover letter, CV, and dates of availability to alm...@disl.org by *17 November 2023* to be considered. Resources for the construction of such documents are available online and at most institutions? Career Services departments, such as https://www.southalabama.edu/departments/careerservices/job.html and https://pathwaystoscience.org/Grad.aspx. Preference will be given to applicants who can stay through the entire internship period. Application review will begin immediately. DISL is an equal opportunity employer and encourages applications from a diverse pool of prospective interns without regard to race, color, religion, sex, sexual orientation, gender identity, gender expression, national origin, age, protected veteran or disabled status, or genetic or any other identity information. DISL and ALMMSN recognize that a diversity of perspectives, lived experiences, ideas, and passions allows us to better meet our goal of ocean-literate communities in Alabama and that equity, diversity, and inclusion are fundamental to achieving our mission.
