Deal all, We post the following, hoping for a species ID. These photos were taken by "Shahariar Md. Shahbuddin" Thanks Rubaiyat Mansur Mowgli Project Co-ordinator Bangladesh Cetacean Diversity Project. ____________________________________________________________________ newspaper articles published in "The Daily Star", 30.July 2007: Large blue whale found dead on Ctg beach Staff Correspondent, Ctg A dead blue whale was found on Kattali sea beach of Pahartali yesterday, which zoologists termed unusual for Bangladesh territory. "From the picture, I guess the whale could be around 50 feet long. I think it was swept away to Bangladesh water territory from the Indian Ocean after succumbing to its injuries," said Md Monzoorul Kibria, an assistant professor of zoology in Chittagong University. "It is a blue whale that is generally found in the Indian Ocean, South Pacific Ocean, Atlantic Ocean and deep in the Bay of Bengal," he said. Local fisherman Sujan Jaldas, who first noticed the whale near the sea shore at around 1:30am, said, "I along with some fellow fishermen was fishing in the sea near the Kattali coast when I suddenly noticed something very big floating around our trawler. We got frightened and soon left the area for the shore." "In the morning we went to the shore again to have a glimpse of the animal. It was so big, really awesome!" Sujan said. The spot at Rani Rasmoni Ghat assumed a festive look as people from neighbouring areas rushed to see the whale. Some boys climbed on it and started dancing. There were injury marks on the whale's abdomen. A grown-up blue whale (valaenoptera musculus) can be 110-foot long and can swim up to 50 km per hour, Prof Kibria said. He urged the authorities to preserve at least the bones of the whale at some museum. Pahartali police said they had informed all the authorities concerned about the whale. ____________________________________________________________________________-- Elisabeth Fahrni Mansur Cell: ++88 01711 524887 Rubaiyat Mansur Mowgli Cell: ++88 01711 696336 home: ++88 02 9344770 Sundarban Forever!

Available online 18 May 2007. Toothed whales produce short, ultrasonic clicks of high directionality and source level to probe their environment acoustically. This process, termed echolocation, is to a large part governed by the properties of the emitted clicks. Therefore derivation of click source parameters from free-ranging animals is of increasing importance to understand both how toothed whales use echolocation in the wild and how they may be monitored acoustically. This paper addresses how source parameters can be derived from free-ranging toothed whales in the wild using calibrated multi-hydrophone arrays and digital recorders. We outline the properties required of hydrophones, amplifiers and analog to digital converters, and discuss the problems of recording echolocation clicks on the axis of a directional sound beam. For accurate localization the hydrophone array apertures must be adapted and scaled to the behavior of, and the range to, the clicking animal, and precise information on hydrophone locations is critical. We provide examples of localization routines and outline sources of error that lead to uncertainties in localizing clicking animals in time and space. Furthermore we explore approaches to time series analysis of discrete versions of toothed whale clicks that are meaningful in a biosonar context.

New article on harbour porpoise population genetics
by Michael Fontaine 26 Jul '07

26 Jul '07

Dear Marmammers, We are delighted to announce you the release of our article on harbour porpoise population genetics in BMC Biology: Rise of oceanographic barriers in continuous populations of a cetacean: the genetic structure of harbour porpoises in Old World waters. Fontaine MC, Baird SJE, Piry S, Ray N, Tolley KA, Duke S, Birkun AJ, Ferreira M, Jauniaux T, Llavona À, Öztürk B, Öztürk AA, Ridoux V, Rogan E, Sequeira M, Siebert U, Vikingsson GA, Bouquegneau J-M & Michaux JR. BMC Biology (2007) 5, 30. If you are interested in, you can download freely the MS at this address: http://www.biomedcentral.com/content/pdf/1741-7007-5-30.pdf All the best, Michaël ABSTRACT: Background Understanding the role of seascape in shaping genetic and demographic population structure is highly challenging for marine pelagic species such as cetaceans for which there is generally little evidence of what could effectively restrict their dispersal. In the present work, we applied a combination of recent individual-based landscape genetic approaches to investigate the population genetic structure of a highly mobile extensive range cetacean, the harbour porpoise in the eastern North Atlantic, with regards to oceanographic characteristics that could constrain its dispersal. Results Analyses of 10 microsatellite loci for 752 individuals revealed that most of the sampled range in the eastern North Atlantic behaves as a 'continuous' population that widely extends over thousands of kilometres with significant isolation by distance (IBD). However, strong barriers to gene flow were detected in the south-eastern part of the range. These barriers coincided with profound changes in environmental characteristics and isolated, on a relatively small scale, porpoises from Iberian waters and on a larger scale porpoises from the Black Sea. Conclusions The presence of these barriers to gene flow that coincide with profound changes in oceanographic features, together with the spatial variation in IBD strength, provide for the first time strong evidence that physical processes have a major impact on the demographic and genetic structure of a cetacean. This genetic pattern further suggests habitat-related fragmentation of the porpoise range that is likely to intensify with predicted surface ocean warming. -- Michael C.

The three new RFPs are as follows: RFP 07-05 requests proposals for a review of the existing literature on population modeling, specifically addressing the relative importance of various vital rates to population trends in marine mammals. RFP 07-06 requests proposals for developing the transfer functions in the PCAD (Population Consequences of Acoustic Disturbance) model that was developed by the National Research Council. RFP 07-07 requests proposals to develop a new tool for risk assessments that are used by the oil and gas industries. The deadline for filing proposals under RFP 07-01 has been extended from August 13 to August 17. This change is official and will appear on our web site in the near future. This RFP calls for development of software to be used in Passive Acoustic Monitoring (PAM). Please do not reply to this email.

volounteers needed urgent for Southern Great Barrier Reef inshore dolphin project
by Daniele Cagnazzi 26 Jul '07

26 Jul '07

PROJECT TITLE: SOUTHERN GREAT BARRIER REEF INSHORE DOLPHIN PROJECT RESEARCH CENTRE: Southern Cross University Whale Research Centre The SCUWRC is a cetacean centre that was established in 2001 at Southern Cross University in Lismore, NSW, Australia. The principle objective of the centre is to undertake research on cetacean populations in the Southern Hemisphere. Daniele Cagnazzi PhD student at SCUWRS is looking for volunteers, to cover the period from August 2007 to Septmber 2007 to assist the researcher during the field work. We conduct boat-based research with the primary objective to investigate population parameters, size, social dynamics, habitat preference, movement, range, seasonal occurrence and abundance and pattern of diurnal behaviour of Snubfin dolphin and Indo-Pacific Humpback dolphin along the Fraser/Curtis Coast. Furthermore, we collect occasional information on all the cetacean species, mainly members of the Delphinidae family, sighted during the surveys. We also work closely with local communities, environmental agencies, and government organisations to educate the general public and to promote a general awareness and understanding of the significance of Cetaceans. The primary aims of the project are: 1) To estimate the distribution and abundance of the inshore dolphins ( primarly Snubfin and Indo-Pacific Humpback dolphin) in the Southern Great Barrier Reef Region. 2) To investigate the population structure of inshore dolphin species in Central Queensland 3) To identify key habitats for dolphins feeding and resting and socialising. 3) To collect data of any other species recorded in the study area. The field work will be conducted on a daily basis on the 6m research vessel, Sousa, mainly in coastal waters and estuaries. Volunteers will share a house close to the beach with the researcher and the rest of the team but will have to partecipate to the accomodation and food costs. Accomodation including power, water, phone, internet line and the food used on the boat are provided at 50$ per week. Applicants please reply to my e-mail address, dcagna10(a)scu.edu.au, attaching a CV, including previous experiences and background studies.
