    ABSTRACT: On the Island of Ireland, pine martens (Martes martes) exist at the western edge of their global geographic range in the least forested region of Europe. The species has undergone substantial declines in abundance and distribution during the 20th century. Here, we report on the first cross-jurisdictional (Republic of Ireland and Northern Ireland) survey that aimed to investigate current pine marten distribution, assess any recent historical change and provide preliminary estimates of population abundance.A standardised non-invasive survey technique that used scat-based transect surveys and DNA analysis to confirm scat identity was deployed in 258 10 km national grid squares during 2005–2007. In the Republic of Ireland, an occupancy rate of 59.6% was found. Comparisons with historical data indicated that a range expansion of pine marten had occurred over the last 30 years. Indicative core population range extended to over 50% of the land area with population abundance estimates of 2740 individuals.In Northern Ireland, an occupancy rate of 56.7% was determined with the population largely concentrated in western areas. There was little or no evidence of any recent expansion from core population areas (18% of land area) despite recent increases in forest cover and full legal protection. Population abundance estimates of 320 emphasise the critical requirement for action to conserve this species.The pine marten is one of the rarest wildlife species in Ireland and, based on our studies, an evidenced based conservation strategy that promotes a sustainable future for the species needs to be developed.

    ABSTRACT: ABSTRACT The impacts of pathogens and parasites and their associated diseases are integral to understanding potential threats to Martes populations. In this chapter, we summarize the known relations of pathogens and parasites to their Martes hosts and review the epidemiology and life cycles of 4 selected pathogens that may be particularly important to Martes species, including rabies viruses, canine distemper virus, parvoviruses, and Toxoplasma gondii . We also address management options for dealing with disease issues and their implications for conservation efforts for Martes species. These implications include disease risk in reintroduction programs, handling of potentially diseased individuals, and protocols for disease assessment and prevention. Finally, we suggest future directions and roles of wildlife disease ecology in the research and management of Martes species. Our overall goal is to provide information that will be helpful for wildlife biologists, wildlife veterinarians, and others concerned about the biology, management, and conservation of Martes species.

    ABSTRACT: An hair trapping protocol, with camera trapping surveillance, was carried out on the south-western side of the Etna, inhabited by an abundant population of the European wildcat. We aimed to collect hair for genetic analysis on the base of a field study conducted in Switzerland, where valerian tincture had been used to attract wildcats to rub again wooden sticks and therefore leaving hairs. We placed 18 hair trapping stations, plus one camera trap per scented wooden stick, 1 km away from each other for 60 days (October 29 2010 to December 28 2010). The rate of "capture" success (1 capture / 24.5 trap-days) by camera trapping was substantially the same as those obtained during previous surveys performed in the same study area without the use of any attractants. No wildcats were photographed while rubbing against the wooden sticks, neither any wildcat was interested in the scent lure. We discuss limitations of the hair trapping, providing possible explanations on the failure of valerian tincture, while suggesting some field advices for future monitorings.
