harbour porpoise click train patterns
by Sven Koschinski 06 Dec '05

06 Dec '05

Dear all, as a part of a study using porpoise click detectors (T-PODs)in a windfarm area I want to compare patterns within click trains or click train series obtained at two T-POD locations (inside and outside the windfarm). For this purpose I am working out a literature study on meaningful click patterns and their possible purpose in a behavioural context. Much of the information needed seems to be hidden in papers dealing with biosonar performance. I would appreciate every piece of literature (peer reviewed, conference proceeding, working papers etc.) which helps to define categories for my study. I already found following papers: Au, W. W. L. 1993. Sonar of dolphins. Springer. New York. 277 pp. Au, W. W. L., R. A. Kastelein, T. Rippe, & N. M. Schooneman. 1999.

Final announcement for workshop "Considerations of Mitigation Tec hniques to Reduce Small Cetacean Bycatch in Fisheries" at SMM Conference
by LawsonJ＠DFO-MPO.GC.CA 05 Dec '05

05 Dec '05

Hello all, We are in the last few days running up to the SMM conference and I wanted to post a final announcement regarding the workshop "Considerations of Mitigation Techniques to Reduce Small Cetacean Bycatch in Fisheries", to be held Saturday, December 10th, 2005 at the Manchester Grand Hyatt San Diego, San Diego, California. There are spaces remaining for this event and those who have not yet contacted me to add their name to the participants' list are encouraged to do so. With some effort I have been able to keep registration costs down to $20US so as to assist student attendees, while still having two coffee breaks. Registration will take place on Saturday morning at 0800 at the venue (room Elizabeth F, second floor). A variety of international speakers will be presenting lead-off talks, with attendees encouraged to contribute to the ensuing discussions. The agenda is: Workshop Agenda 0900 - Scope of the small cetacean bycatch problem worldwide As this aspect of the topic has been covered in detail by several workshops and scientific committees recently, I think it better to cover topics where much effort is now concentrated 0930 - Why and how are small cetaceans caught in fishing gear? A review of the reasons why, and the ways how, small cetaceans are bycaught in gear. Are small cetaceans caught in nets due to a detection or target classification problem? Why are dolphins and larger whales caught in pelagic trawls? 1000 - 15 minute break 1015 - Bycatch Mitigation Approaches (1) Mechanical methods to reduce bycatch new net technologies to facilitate release or exclusion alternatives to gillnets for some fisheries (e.g., fish "pots" for groundfish) "coated nets" to enhance their detection by small cetaceans (2) Acoustical methods to reduce bycatch "traditional" pingers "responsive" pingers ADDs 1245 - 45 minute lunch break 1330 - Bycatch Mitigation Approaches (continued) (3) Operational methods to reduce bycatch modified net deployment patterns, depths etc. closed areas, seasons, or times 1500 - 15 minute break 1515 - Experiences in the challenges of management and public support of mitigation implementation voluntary implementation legal approaches 1600 - Modelling of Mitigation Effectiveness risk analysis (e.g., when is mitigation no longer necessary, or of sufficient benefit relative to cost? How do we test mitigation effectiveness?) can there be different objectives for mitigation (i.e., zero mortality vs. sustainable removals) 1700-1730 - Wrap up and final discussions Other details can be obtained by contacting me via e-mail or phone, or by going to the web link at the UN site from the SMM conference page. I look forward to seeing you all there!

barnacle Xenobalanus globicipitus
by ekane＠southampton.liu.edu 05 Dec '05

05 Dec '05

Hello, I am a Long Island University, Southampton College student currently participating in an internship at Southwest Fisheries Science Center (NMFS/NOAA) under the supervision of Tim Gerrodette and Paula Olson. My research project is on the commensal whale barnacle Xenobalanus globicipitus within the eastern tropical pacific. I have found 4 species that have been previously unrecorded to my knowledge. They are Humpback whales, Spinner dolphins, Bryde's whales, and long-beaked common dolphins (D. capensis). If anyone has seen this barnacle on any of these cetaceans, or any cetaceans for that matter, could you please let me know. I am also trying to compile a list of known hosts and occurrences, so this information can be helpful. For a picture of this barnacle, see http://ip30.eti.uva.nl/bis/crustacea.php?menuentry=soorten&selected=beschri… Below is an alphabetical list of references that I have obtained.

New Publication - Behaviourally specific preferred associations in bottlenose dolphins
by Shane 05 Dec '05

05 Dec '05

We are pleased to announce the publication of the following article in the Canadian Journal of Zoology: S. Gero, L. Bejder, H. Whitehead, J. Mann, and R.C. Connor. (2005) Behaviourally specific preferred associations in bottlenose dolphins, Tursiops spp. The article is available online CONTENTS section at http://cjz.nrc.ca (this may only be available free to Canadian's). Alternatively, a pdf reprint is available from the corresponding author's website under publications: http://whitelab.biology.dal.ca/sge/pub.html ABSTRACT: We investigated association patterns of 52 photographically identified, free-ranging bottlenose dolphins (Tursiops spp. Gervais,1855) across four behavioural states (rest, travel, social, foraging/feeding) to investigate how behavioural state influences patterns of association. Group composition and behavioural data were extracted from 2178 encounter surveys collected over 3 years. Analyses revealed three general types of association: (1) affiliates, which consistently demonstrate preferred associations across all behavioral states; (2) acquaintances, which never form preferred associations but still associate in at least one behavioural state; and (3) behavioural associates, which form preferred associations in at least one, but not all behavioural states. The majority of associations in Shark Bay, Australia, are acquaintance type (38.2%), with affiliates (5.7%, principally between adult males) and behavioural associates (28.9%, principally between juveniles) being relatively rarer. Permutation tests identified behaviourally specific preferred associations during all behavioural states. Although behaviourally specific preferred associations appear to exist with the Shark Bay social structure, it seems that the social organization and mating system constrain the social relationships for the majority of males and females in differing ways which prevent them from having behavioural associates, leaving juveniles free to associate based on short-term expediency and behavioural specific needs. *********************************** Shane Gero, M.Sc.

assistants needed for Shark Bay study
by Richard Connor 04 Dec '05

04 Dec '05

Please post the following on marmam: We are seeking four or five highly skilled research assistants for the 2006 field season to help on the Male Dolphin Alliance Project in Shark Bay, Western Australia. The study will run from July-November. We are examining the relationship between alliance size, stability, habitat, relatedness and reproductive success. Shark Bay is a marine biologist's paradise and the dolphin behavior you will witness is unsurpassed. Because training time will be limited and we (Connor and Krutzen) will not be on site for the entire study, we need people who are already skilled at handling small motor boats and dolphin photo-identification. Skill at sailing larger (36') catamarans would be a real plus. You will work in teams on two boats, one concentrating on behavior and the other on darting and behavior. Behavioral data will be collected during surveys and focal alliance follows, including 20- minute digital video samples. The type of person that works well on our project is hard-working, team oriented, plays well with others and maintains a positive attitude when things aren't going well. People who like to 'sleep in' or work on a schedule may not adapt well to our program. The latter is important because, perhaps more than many field sites, work in Shark Bay is highly weather dependent. This means we can alternate between long periods stuck on shore and consecutive long-days offshore which are very intense and tiring. The fickle nature of the wind means we can rarely predict what time of day we will be going offshore and are often 'on standby'. You should be comfortable with standing in a boat for 11 hours non-stop while looking for and recording data on dolphins. You should be comfortable with and experienced at looking though binoculars for long periods. You will be expected to work endless hours identifying dolphins and entering data into a computer database. You must be available from July-November 2006, but exact dates within that period are still uncertain. We will also send you a CD with over 100 male fins and expect to learn to distinguish them before the study. You have to get to Shark Bay on your own, but food and living space is provided onsite. If you are interested and have the required experience and skills, please provide a short CV with references and a letter explaining your interest in the project and career goals to both Richard at rconnor(a)umassd.edu and Michael at <mailto:michael.kruetzen@aim.unizh.ch>michael.kruetzen(a)aim.unizh.ch by 31 Jan 06. We will make decisions by the end of February. Please include names and email addresses for references; CVs that state 'references available on request' will not be considered. Please specify whether you actually took pictures on a photo-ID study (but that is not a requirement; we have had wonderful assistants with no prior boat or photo-ID experience). Please do not be put off if you applied but were not considered in recent years. Each year we have more good applicants than we can take on the project. Richard will be at the San Diego Conference and will be happy to speak with you.

There is a new book titled "Environmental Issues in Latin American and the Caribbean" published by Springer which contains two chapters that refer to marine mammal issues. The chapter titles and summaries are below. For more information on this book go to: http://www.springer.com/sgw/cda/frontpage/0,11855,4-40157-22-88521011-0,00.… Thanks, Aldemaro Romero, Ph.D. Chair and Professor Department of Biological Sciences Arkansas State University P.O.

Current Address: Department of Biological Sciences, Arkansas State University, P.O. Box 599, State University, AR 72467; 2 Environmental Studies Program, Macalester College, 1600 Grand Ave., St, Paul, MN 55105-1899. Current Address: Yale School of Forestry and Environmental Studies, 205 Prospect Street, New Haven, CT 06511 Abstract: Although some progress has been made toward a better understanding of marine mammal utilization in the Southeastern Caribbean, no comparative analysis has been carried out to see how such practices originated, developed, and finally impacted the marine mammal populations in that region. We conducted field and archival studies for Venezuela, Trinidad and Tobago, Grenada, Barbados, and St. Vincent and the Grenadines. We analyzed records of whaling, dolphin fisheries, and manatee exploitation for those countries, interviewed local fishers, and explored the remains of whaling stations in each area. Our results show that each of these countries developed a different pattern of whale and dolphin exploitation, but similar patterns of utilizing manatees. We conclude that these five neighboring countries, although sharing essentially the same marine mammal species, developed different exploitation practices in terms of species targeted, capture techniques, and time periods in which that exploitation took place, due to different cultural circumstances. Key words: whaling; dolphin fisheries; whales; dolphins; manatees Chapter 7 A DEEPER SOLUTION FOR THE INTERNATIONAL COMMONS Building an effort control regime for the Eastern Tropical Pacific tuna fishery Brian Potter1 1Department of Political Science, The College of New Jersey, Ewing, NJ 08628-0718 Abstract: The parable of the tragedy of the commons tells that resources held under open access conditions are prone to over-exploitation. For fisheries, regulations to limit aggregate catch improve resource use yet promote over-investment. Optimal regulation would limit the investments and labor dedicated to harvesting, a task quite difficult in a global forum. Motivated by three reasons, the member-states of the Inter-American Tropical Tuna Commission have attempted such limits for the purse-seine yellowfin fishery, in addition to implementing other conservation measures. First, increases in fishing capacity by existing participants and newcomers have resulted in financial losses for the major fleets. Second, the resolution of the tuna-dolphin controversy encouraged additional harvesting capacity in an already-crowded fishery. Finally, bureaucratic changes in some countries have empowered fishery professionals who balance sustainable resource use with economic development. The strength of these influences, as well as efforts and concessions to create a regime, vary among the states involved. Key words: fishery management, natural resource policy, common property, open access, over-capitalization, Inter-American Tropical Tuna Commission, Latin America.

DOLPHIN PHOTO-IDENTIFICATION INTERNSHIP The Marine Mammal Research Program (MMRP) is currently accepting applications for Research Interns for the Spring/Summer 2006 semester (mid-February, 2006 - July 31, 2006). The MMRP is located on Galveston, southern Texas. Our research lab is coordinated under the auspices of the Institute of Marine Life Sciences (IMLS) at Texas A&M University in Galveston (TAMUG). Research studies can vary widely in nature and availability. For information on past or current research projects at MMRP, please visit our website, at http://www.tamug.tamu.edu/mmrp/ Internships at MMRP represent an opportunity to get "behind the scenes" to see how a marine mammal facility operates. It offers an excellent opportunity for motivated individuals to participate in MMRP's ongoing research projects and to obtain laboratory training in photo-identification methodology and analysis under the mentorship of experienced marine mammal researchers. In addition, educational opportunities are available, such as informal journal article reviews and the development of personal learning objectives. Successful applicants will be primarily responsible for assisting with lab-based photo-identification tasks. Other responsibilities may include but are not limited to data entry into the computer for analysis, library research, and involvement in special projects. This coming year, we will not be engaged in gathering data from vessels, although some limited shore-based work with bottlenose dolphin position information may be possible. Therefore, please be advised that this is primarily an intensive laboratory-analysis experience with marine mammals. Internships require a minimum of a 12-week commitment (16-20 weeks is preferable), 40 hours per week. Starting and ending dates are flexible. There is no compensation for this internship position and successful applicants will be responsible for their living and transportation expenses during the time of the internship. Successful candidate will also be responsible for providing their own housing. However, MMRP will provide assistance in locating housing and/or matching up interns desiring roommates. * Qualifications required: - Must have basic computer proficiency; Microsoft Access literacy preferred - Successful candidates will be ready and willing to learn, self-motivated, and flexible. - Prior research experience is recommended, but not required. * The deadline for application is 16 January, 2006, and must contain the following: 1. Curriculum vitae, or "resumé", 2. Letter of intent, which clearly spells out what you would wish to accomplish with the internship, 3. Two letters of reference, from professors or research supervisors who are familiar with your scholarship, research skills and work habits, 4. A letter listing classes taken and grades obtained. An official transcript is not necessary, but a copy is appreciated. Please send the above materials to : Marine Mammal Research Program, Attn. Internship Coordinator, 4700 Ave. U, Bldg. # 303, Galveston, TX 77551. Interested applicants should correspond to: Dr. Gwenael Beauplet Marine Mammal Research Program Institute of Marine Life Sciences, Texas A&M University 4700 Avenue U, Bldg #303, Galveston, TX 77551, USA Email: ufuf(a)tamug.edu <mailto:ufuf@tamug.edu>
