From the Chair The 4th International Martes Symposium demonstrates once more that MWG is unique Gilbert Proulx Alpha Wildlife Research & Management Ltd. 229 Lilac Terrace Sherwood Park, Alberta Canada T8H 1W3 gproulx@alphawildlife.ca In the past, I often claimed that the Martes Working Group was a unique professional organization made up of dedicated, leading wildlife scientists. The 4th International Symposium in Lisbon, Portugal, proved me right once again. While the facilities were more than adequate, the organization was impeccable. The symposium brought together scientists from 15 different countries. It also sponsored scientists who required travel assistance; this made us aware of research programs conducted in Lithuania, Hungary, Belarus, Russia, and a few other countries. The programme was diversified and addressed Martes taxonomy, distribution, ecology, species interactions, conservation, management, and research techniques. The oral presentations were all outstanding; posters were most informative. We all enjoyed exceptional food, outstanding entertainment, and a memorable field trip in the Serra de Grândola. I tip my hat to Margarida Santos-Reis, Johnny Birks, John Messenger, and all the members of the Organizing Committee for providing our membership with a unique experience. They successfully met our objective to attract the attention of European wildlife researchers and managers. Many of us thought that the Symposium was one of the best scientific meetings we had ever been to. It was an electrifying experience and, not surprisingly, we soon had people offering to organize the next symposium. The 5th International Martes Symposium will be held in Western United States, in 2008. We had a productive MWG membership meeting. First of all, we elected an Executive for the next four years:

§ Chair / Gilbert Proulx (re -appointed) § Treasurer-Secretary / Erin O’Doherty (re-

appointed) § Newsletter Editor / Amie Mazzoni § Webmaster / Jean-François Robitaille (re-

appointed) We intended to elect a Vice-Chair who

would represent our membership outside North America. We could not get a volunteer for the position, and we elected Johnny Birks “in absentia”.

Unfortunately, Johnny had to decline his involvement at the Executive level. Because our group is relatively small, we decided to postpone the election of a Vice-Chair until the next symposium in 2008. It is with exceptional efficiency that Erin managed our membership these last four years, and I am pleased to see that she accepted to continue to take care of business! Amie Mazzoni is our new Editor. She will replace Steve Buskirk, who did an outstanding job keeping us informed about Martes activities around the world. In order to eliminate publishing and mailing costs, the Executive decided that the Newsletter would now be digitalized and distributed through emails (with a few exceptions for those members without access to computers). The activities of the Executive will remain the same. In his acceptance speech, Webmaster Robitaille indicated his intentions to render our website more interactive. Also, he welcomes any suggestions that our members would like to make in order to improve our site. After discussing our group’s scientific and educational role, the membership mandated the Executive with the task to investigate the possibility of becoming a registered, non-profit society (motioned by Johnny Birks, seconded by Tom Kucera; unanimously accepted). It was felt that such a status could attract the attention of governments seeking professional opinions, and give greater exposure to MWG. It could also facilitate recruitment of funds from individuals and corporations to maintain our efforts to educate the scientific community and the public about Martes. We will explore our options, and we will report to our membership before making a final decision. Twelve drawings were submitted for our logo contest by Roger and Consie Powell, Brian Long, my son Benjamin and myself. They were all very interesting drawings and I sincerely thank all the participants. A logo submitted by the Powell’s won the favor of our membership and will now be used on our letterheads and newsletter. As in the past, MWG will publish Proceedings from the Symposium. The Editorial Committee, consisting of Margarida Santos-Reis, Johnny Birks, Erin O’Doherty and myself, has initiated the peer-review of more than 20 papers. The release of the Proceedings is scheduled for summer 2005. The Proceedings of the 3rd International Martes Symposium have now been published (D. J. Harrison, A. K. Fuller, and G. Proulx, editors – Springer Publ.). This new MWG contribution stresses the fact that efforts to successfully conserve and manage martens and fishers are associated with efforts to maintain structurally complex forests and

Martes Working Group Newsletter 12(1) 2004 3

manage sustainable harvest programs. Despite great strides in our understanding of Martes life histories, there are still many unknowns about their ecology and conservation. I hope that this new book, the symposium that we just experienced, and the upcoming proceedings will all be incentives for new researchers to join our unique group of dedicated professionals. We have a strong base; let’s publicize our accomplishments and recruit active members who will contribute to the conservation of martens and fishers.

THE 4th INTERNATIONAL MARTES SYMPOSIUM:

Martes in Carnivore Communities Margarida Santos-Reis Lisbon University, Portugal For the first time, the Martes symposium was held outside North America, with its fourth edition taking place at Lisbon University (Portugal) from the 20th to the 24th of July 2004 (http://dba.fc.ul.pt/martes2004). The purpose, besides facilitating communication among people with a shared interest in research, conservation and management of Martes species, was to encourage broader geographic representation both in terms of researchers and species. This aim was achieved with the participation of approximately 80

Martes Working Group Newsletter 12(1) 2004 4

delegates from 15 countries. Representatives from Canada, USA, UK, Ireland, Portugal, Spain, France, Italy, Netherlands, Hungary, Poland, Russia, Bielorussia, Lithuania and Japan were present and presentations addressed the eight Martes species (M. americana, M. pennanti, M. martes, M. foina, M. melampus, M. flavigula , M. gwatkinsi and M. zibelina). The scientific programme included 45 presentations (31 oral and 14 poster) organized in five thematic sessions: I - Martes variability, distribution and status, II – Martes ecology, III – Martes conservation and management, IV – Martes interactions and V – Martes research techniques . William Zielinski (USA), Sim Broekhuizen (The Netherlands) and Midori Saeki (Japan) were the invited key-note speakers, each of them addressing Martes issues in the 21st century and lessons to learn respectively from North America, Europe and Asia. The level of attendance at the scientific sessions was high as was participation of delegates in the discussion. The social programme played an important role in creating a positive atmosphere among delegates at the symposium. It was diversified and fun, and included an opening reception at the Porto and Douro Wines Institute; a banquet with an equestrian gala showing the versatility of the horse in a number of disciplines and fado singing (the traditional Portuguese song); a Portuguese wine tasting session prior to the Martes Working Group meeting; and a field trip to the cork oak woodland of Serra de Grândola, where a lunch with traditional Alentejo food was served in the University field station, which ended with a swim in the nearby Atlantic ocean. To raise funds for the next Symposium, delegates were asked to bring gifts from their countries and, during the banquet, raffle tickets were sold for small items , and a silent auction took place for the most original and/or valuable ones. Johnny Birks and John Messenger (UK) took the lead on one of the best and most comical moments of the Symposium. As for the previous editions of the Martes symposium, the proceedings will be published as a book, edited by Gilbert Proulx, Johnny Birks, Erin O’Doherty and myself. We had 20 manuscripts submitted for consideration, which have been mailed to reviewers and are awaiting revisions. Our goal is to receive all revised manuscripts and inform the authors by November. On behalf of the organising committee, my thanks go to the Martes Working Group (for giving us this opportunity), the national and international funding and/or supporting entities (specially Vincent Weir for

the travel subsidies for several delegates), the invited speakers (for their thoughtful insights), all presenters (specially those who submitted manuscripts), the scientific committee and moderators (for the quality of the papers selected and for keeping the track of the speakers) and, last but not the least, Francisco and my research team (specially Hugo and Maria João) for being there when needed…

Reproductive capabilities of female sables 7 years and older Vladimir G. Monakhov Institute of Plant and Animal Ecology (RAS) 8 Marta St., 202. 620144 Ekaterinburg, Russia E-mail: mon@ipae.uran.ru In an effort to learn more about sable reproduction, I compared the fertility of 2765 >7-year-old females (litter size) to that of 60 wild individuals (number of corpora lutea) from Transurals and West Sayan. The litter size of >7-year-old females bred in captivity rarely exceeded 7 kits (0.1%: two litters of eight and one litter of nine). Eighty-seven (3.2%) and 9 (0.3%) females had 6 and 7 kits, respectively. Other females had < 6 kits or were barren. Mean fertility decreased with age; the number of barren females sharply increased after 13 years of age. In contrast, only 1 wild individual had 8 corpora lutea. Four (6.7%) and 3 (5%) females had 6 and 7 corpora lutea, respectively. Other females had < 6 corpora lutea or were barren. I believe that fertility of females from the Transural Region is higher in the wild than in fur farms.

Searching for microevolutional trends in Transural Martes Vladimir G. Monakhov Maryana N. Ranyuk Institute of Plant and Animal Ecology (RAS) 8 Marta St., 202. 620144 Ekaterinburg, Russia E-mail: mon@ipae.uran.ru In the Transural Region, sables and pine martens live in sympatry over 30% of the territory. With support from the Russian Foundation for Basic Research, we will be investigating phenotypic and demographic characteristics of these two species. As we have access to a significant collection of specimens, we may be able to learn more about microevolutional trends in Transural Martes.

Preliminary results of nephritis research in the marten population

Dean Konjevi c Chair for Game, Biology, Pathology and Breeding The Faculty of Veterinary Medicine University of Zagreb Heinzelova 55, Republic of Croatia dean.konjevic@vef.hr Preliminary results of the research into the nephropathy of stone and pine martens revealed a high occurrence of kidney inflammation. From 2002 to 2004 we collected 9 stone and 4 pine martens. Eight of thirteen martens were killed during regular hunting operations on the areas of Desinici, Pokupski bazen, Požega and Županja. The rest of the carcasses were collected as victims of road traffic accidents (3) and of dog attacks (2). Following dissection, kidney samples were taken for histopathological analysis. Samples were prepared using the standard paraffin method and coloured by haematoxylin-eosin. Histopathological analysis of the kidney tissue revealed interstitial nephritis in 6 animals, glomerulonephritis in 2 animals and one case of tubular necrosis. Four of thirteen samples were negative or inappropriate for analysis due to the developing autolysis. Since the interstitial nephritis is mainly a result of bacterial and viral infections, samples for bacteriological (namely leptospirosis) analysis were also taken during necropsy. The results of bacteriological analysis were negative in the majority of samples; other ones were inappropriate for objective analysis. The urinary system is the most important excretion system of the body, and is therefore influenced by many harmful antigens. Beside the bacterial cause of nephropathy already mentioned, it can be also initiated by different toxicants (i. e. Cadmium) or immunological reactions. Chronic exposure to low levels of Cadmium can be the cause of epithelial dystrophy in kidney tubules and in some cases it may develop into tubular necrosis. To recall, tubular necrosis was observed in one marten. The position of martens on the top of the food chain only amplifies the possibility for kidney injuries, both inflammatory and dystrophic. The final results of the study should shed light on the question of marten nephritises in Croatia.
