International Whaling Commission meeting in Rome


Between 9-11 March the Intersessional Meeting of the Commission on the Future of IWC (International Whaling Commission) took place in Rome.

Three main news came after the meeting: 1) Japan may be allowed to conduct commercial whaling near its coast while scaling down its activities in the Antarctic, 2) South Korea said that it is ready to resume commercial whaling, and 3) IWC wants to shortcut the scientific process and authorise a Small Working Group of member countries to continue developing a package deal of proposals for a resumption of commercial whaling, relying instead on ad-hoc catch limits set for five years at a time, without regard to long-term sustainability.

Conservationists consider the decisions taken during this meeting as a dangerous change of course which jeopardises the future of whales. “Coastal whaling for Japan would legitimise what Iceland and Norway are doing” said Nicolas Entrup from WDCS, and his colleague Mark Simmonds added “This is dreadful and terrifying news, South Korea’s announcement fulfils our worst expectations. We feared that the deal-making that has been going on would encourage other countries to join in and in the fullness of time lead to an expansion of whaling and this now seems to be exactly what is happening.”

Conservation and animal welfare organisations point of view are well summarized in a comment by Patrick Ramage, IFAW’s Global Whale Programme Director: “Science has been thrown to the whalers like Christians to the lions in ancient Rome... The message from the Commission was forget science, forget sustainability, compromise full steam ahead”.

A Conservation Plan is not a conservation success

"A Plan is not a conservation success. A conservation success is when there is more of the things you want to conserve than it used to be. (...) If your Plan does not work treat it as an experiment and change the rules."

First International Conference on Marine Mammal Protected Areas


The First International Conference on Marine Mammal Protected Areas is going to be held from March 29th to 3rd April, in Maui, Hawaii.

The conference will be characterized by a combination of presentations, panels, posters, workshops and training sessions, conceived by a steering committee of marine mammal and MPA experts from around the world. MPA managers, scientists, and educators and policy-makers will be engaged in sessions that will provide a forum for sharing information, common challenges and solutions on approaches to marine mammal management and conservation. The aim of the meeting is also to foster networking between marine mammal MPAs which share populations and issues.

Two Tethys members have been invited to attend this conference: Giuseppe Notarbartolo di Sciara and Simone Panigada. Giuseppe will bring his experience with the Pelagos Sanctuary during a plenary talk called ‘Managing MMPAs’, Simone will be the panel coordinator of ‘How can networks of MPAs ensure threat mitigation to cetaceans?’

Amvrakikos Gulf: new photo-identification data


The research project ‘Dolphins of Greece’, conducted by Tethys in the Amvrakikos Gulf, has recently completed the analysis of photo-identification data pertinent to the whole 2008.

A total of 3,818 selected digital photos, obtained from January to December during sightings along survey transects that cover the whole gulf, allowed to photo-identify 115 individual bottlenose dolphins.

Most of these recognizable individuals are well-known and were already present in the catalogue started in 2001 , but four of them are new animals never seen before.

Ten of the 115 dolphins were sighted together with immature individuals (newborns, calves or juveniles) and this looks like a promising sign for this highly-resident population that lives in a semi-closed eutrophic gulf.

Photographs included a number of non-identifiable animals, i.e. individuals carrying no distinctive marks on their dorsal fins. These, as well as all the subadult classes, should be added to the number of animals sighted in 2008. So, at present, it appears that the total number of animals seen in the Gulf last year is consistent with the population estimate of 150 made in previous years (Bearzi et al. 2008).

Ongoing monitoring will allow researchers to gain insight into the ecology and trends of this unique bottlenose dolphin community.

European Cetacean Society Conference 2009 (2)


La città di Istanbul ha ospitato nei giorni scorsi il 23° congresso dell’European Cetacean Society, portando la manifestazione ai confini orientali dell’Europa.

Anche quest’anno Tethys è stata presente con una nutrita delegazione di 14 elementi provenienti da tutti i progetti, confermandosi un istituto di ricerca sempre attivo a livello internazionale. A guidare il gruppo Simone Panigada, presidente dell’ECS, che ha presentato un poster con cui ha spiegato i risultati di un survey riguardo le stenelle nel santuario Pelagos.

Il tema conduttore di quest’anno era incentrato sui cambiamenti climatici e i mammiferi marini, e ha visto la partecipazione come oratori invitati di Temel Oguz, Mads-Peter Heide-Jørgensen e Randy Wells che hanno rispettivamente parlato degli effetti del climate change sulle popolazioni che studiano rispettivamente nel Mar nero, nell’Artico e lungo la costa di Sarasota, in Florida.
I primi due giorni sono stati dedicati a workshop che hanno affrontato sia tematiche tecniche come la foto identificazione e la telemetria, sia argomenti di conservazione delle specie in pericolo come la foca monaca.

Il workshop che ha raccolto più partecipanti è stato dedicato agli zifidi, animali al centro della ricerca acustica negli ultimi anni, a causa degli spiaggiamenti di gruppo connessi con i sonar a media frequenza utilizzati dai militari nelle acque di tutto il mondo. Al termine della giornata è stato redatto un documento a nome dell’ECS da presentare ad ACCOBAMS, per fissare delle linee guida per la tutela degli zifi dalle letali esercitazioni della marina.

Per tre giorni si sono poi alternati 47 oratori, che hanno dato un quadro di altissima qualità sulla ricerca mondiale nel campo cetologico, alternando giovani studenti ad affermati nomi, tra cui Peter Tyack e Jonathan Gordon.

La poster session ha offerto come sempre la possibilità di confrontarsi in modo diretto con gli autori dei lavori, e di dare nuovi spunti a tutti.

I lavori si sono conclusi con una splendida festa danzante a bordo di una barca lungo le rive del Bosforo, perché in fondo, la forza di questo ritrovo annuale è nelle relazioni che si creano tra i partecipanti, ponendo le basi per future collaborazioni e amicizie.

Infine, per i più mattinieri, il giorno seguente una nuova crociera ha permesso di vedere alcune focene nuotare nelle acque sotto il ponte tra Asia ed Europa.

Istanbul si è rivelata agli occhi dei 300 partecipanti per la millenaria città che unisce storia e cultura di due continenti, e invita tutti a rincontrarsi tra un anno a Stralsund nel nord della Germania.

European Cetacean Society Conference 2009 (1)


The 23rd annual Conference of the European Cetacean Society has just finished. The Conference was held in Istanbul, Turkey, between the 1st and the 4th of March. This has been the first ECS Conference held in Eastern Europe, at the gate between Europe and Asia.

The Conference has been preceded by two days of workshops focusing on the following aspects: moving towards a standardized population estimate approach for monk seals, beaked whales and active sonar, best practices in marine mammal research, technological advances and related analytical methods in pinniped telemetry, reconciling diverse perspectives for cetacean, and designing behavioural studies on cetaceans in the wild.

The Conference theme was "Climate change and marine mammals" and keynote speakers included Temel Oguz (talking about “Impacts of climate variability on the Black Sea ecosystem”), Mads-Peter Heide-Jørgensen (“Arctic marine mammals and climate change”), and Randy Wells (“How might coastal dolphins be impacted by climate change?”).

The Conference has attracted almost 350 participants from as many as 49 Countries, in spite of the usual 30-32 (click on image to enlarge). Several scientists came from eastern Europe and the Black Sea area.

Brave new ocean re-posted


I am going to re-post this in case some of you missed it. It is 1-hour long but worth watching until the end (when it gets more personal and also global).

Brave New Ocean

Some scientists think that Jeremy Jackson is an "environmentalist", which those scientists do not see as a compliment. You can probably judge for yourself, based on your own experience, whether what Dr. Jackson says makes any sense.

Sardine frenzy


Amazing footage on sardines feast frenzy has been caught by a BBC crew.

Each winter, cool ocean currents drive millions of these small fish northwards along the eastern coast of South Africa. Here, common dolphins, sharks, pinnipeds and marine birds take advantage of this natural migration and feed on sardine schools.

The BBC team used helicopter, boat-based and underwater crews to capture the feeding frenzy in extensive detail. This footage helped to reveal more about the way gannets hunt. They don’t simply dive, catching a fish and bringing it back up to the surface, but they ‘arrow’ down to a depth of 10m, then swim a further 20m and finally they charge around like penguins.

It is really incredible how common dolphins and gannets swim centimetres away from sharks, just ignoring these big predators and focusing only on sardines.

On the discovery of new species


The discovery of a new mammal species fills us with joy and positive thoughts and we’re curious to see the new ‘arrival’, but most of the time we don’t really think about what this new discovery is teaching us.

In a recent paper, Paul Ehrlich and Gerardo Ceballos, two biologists from Stanford University and Mexico’s National University, respectively, say the assumption that ‘nearly all mammal species are known to science’ is incorrect. They argue that global animal and plant species diversity is badly underestimated, even within well-studied taxa.

"What this paper really talks about is how little we actually know about our natural capital and how little we know about the services that flow from it," said Ehrlich, adding that the diminishment of biodiversity can have very significant impacts on mankind.

"The economy of nature is what allows us to have a human economy. If we let the infrastructure of nature go down the drain, then we just can't make up for it with human infrastructure... It just can't be done."

Damir


Damir Peršić has died yesterday of heart failure.

Damir, together with his wife Nena, has been one of the strongest supporters and promoters of the Adriatic Dolphin Project in Croatia. His death at such young age brings great sorrow. Damir was a fine artist, ceramist and photographer. With his hands, he could do anything from house construction to the nicest of artworks. He was also a great cook, with an outstanding sense for beauty and taste.

Damir has been one of my dearest friends. His intelligence and humour lighted up my years in Croatia. He was always willing to help, bringing creativity into anything he did. With him, you could talk about dolphin conservation, filmmaking, modern art, meditation, science, religion, the meaning of life... whatever, and he would bring insight and good mood into any discussion.

With Damir, Nena, and their daughter Inja I've had a great time. For several years, they have been my Croatian family and their home was the nest where I could find a refuge in my difficult moments. Damir was always there to provide shelter and friendly advice.

While I haven't seen him for ten years or more, it felt reassuring to know that he was there, in his beautiful house of Veli Lošinj. One cannot imagine that good people may leave in such a way.

Pink dolphin


A rare albino bottlenose dolphin was sighted in the Lake Calcasieu, an inland saltwater estuary in Louisiana (USA). The animal is a juvenile, he’s entirely pink in the whole body and has reddish eyes. This strange dolphin, nicknamed 'Pinky', was first spotted late last year and has become such a tourist attraction that conservationists are warning people to leave it alone...

Grossa è bella


I maschi di megattera (Megaptera novaeangliae) preferiscono accoppiarsi con le femmine più grandi, questo è quanto emerso da uno studio svolto al largo delle coste hawaiane.

Tra il 1997 e il 2002, i ricercatori hanno studiato il comportamento riproduttivo di questi cetacei e hanno scoperto che le femmine più grandi attirano più maschi rispetto alle compagne di normali dimensioni, e che anche i loro piccoli sono più grandi.

La preferenza dei maschi per le maggiori dimensioni femminili viene spiegata dagli studiosi come una tattica riproduttiva: le femmine più grandi sono generalmente quelle con più esperienza e, date le dimensioni, con una maggior quantità di grasso, quindi esemplari più adatti a fornire cure e nutrimento ai loro piccoli. I piccoli, a loro volta, essendo più grandi possono avere superiori probabilità di sopravvivenza, in quanto meno attaccabili da predatori.

Book of the Month: March 2009


Encyclopedia of Marine Mammals – Second Edition

by W.F. Perrin, B. Würsig and J.G.M. Thewissen

2009

Academic Press

---

The long-awaited 2nd edition of the famous Encyclopedia of Marine Mammals has finally been published!

This 1352 pages-long thorough revision of the classic first edition brings this authoritative book right up-to-date. Over 260 articles describe every species in detail, based on the very latest taxonomy, and a host of biological, ecological and sociological aspects relating to marine mammals. The most recent information on the biology, ecology, anatomy, behavior and interactions with man is provided by a cast of expert authors, all presented in such detail and clarity to support both marine mammal specialists and the naturalists.

William Perrin, one of the authors, said “All articles have been updated. New articles have been added to cover new developments in marine mammal science, such as those related to climate change and the interface of ecology and conservation, as well as some established topics not fully explored in the first edition (2002). Significant changes since the first edition appeared extend to the roster of marine mammsl, with the discovery of new species (e.g., Omura's whale) and the extinction of another (the baiji). These and other changes are fully covered. Most illustrations are now in color.”

The 1352 pages book contains 739 illustrations which show every species and document topical articles.
