  • Eurasian Lynx – Your Essential Brief
    Eurasian lynx – Your essential brief Background Q: Are lynx native to Britain? A: Based on archaeological evidence, the range of the Eurasian lynx (Lynx lynx) included Britain until at least 1,300 years ago. It is difficult to be precise about when or why lynx became extinct here, but it was almost certainly related to human activity – deforestation removed their preferred habitat, and also that of their prey, thus reducing prey availability. These declines in prey species may have been exacerbated by human hunting. Q: Where do they live now? A: Across Europe, Scandinavia, Russia, northern China and Southeast Asia. The range used to include other areas of Western Europe, including Britain, where they are no longer present. Q: How many are there? A: There are thought to be around 50,000 in the world, of which 9,000 – 10,000 live in Europe. They are considered to be a species of least concern by the IUCN. Modern range of the Eurasian lynx Q: How big are they? A: Lynx are on average around 1m in length, 75cm tall and around 20kg, with the males being slightly larger than the females. They can live to 15 years old, but this is rare in the wild. Q: What do they eat? A: The preferred prey of the lynx are the smaller deer species, primarily the roe deer. Lynx may also prey upon other deer species, including chamois, sika deer, smaller red deer, muntjac and fallow deer. Q: Do they eat other things? A: Yes. Lynx prey on many other species when their preferred prey is scarce, including rabbits, hares, foxes, wildcats, squirrel, pine marten, domestic pets, sheep, goats and reared gamebirds.

  • Prey Density, Environmental Productivity and Home-Range Size in the Eurasian Lynx (Lynx Lynx)
    J. Zool., Lond.

C. Linnell2*, John Odden2, Erlend Birkeland Nilsen1 and Reidar Andersen1,2 1 Department of Biology, Norwegian University of Science and Technology, N-7491 Trondheim, Norway 2 Norwegian Institute for Nature Research, Tungasletta 2, N-7485 Trondheim, Norway (Accepted 19 May 2004) Abstract Variation in size of home range is among the most important parameters required for effective conservation and management of a species. However, the fact that home ranges can vary widely within a species makes data transfer between study areas difficult. Home ranges of Eurasian lynx Lynx lynx vary by a factor of 10 between different study areas in Europe. This study aims to try and explain this variation in terms of readily available indices of prey density and environmental productivity. On an individual scale we related the sizes of 52 home ranges, derived from 23 (9:14 male:female) individual resident lynx obtained from south-eastern Norway, with an index of density of roe deer Capreolus capreolus. This index was obtained from the density of harvested roe deer within the municipalities covered by the lynx home ranges. We found a significant negative relationship between harvest density and home- range size for both sexes. On a European level we related the sizes of 111 lynx (48:63 male: female) from 10 study sites to estimates derived from remote sensing of environmental productivity and seasonality.

Movements of individuals within and among populations help to maintain genetic variability and population viability. erefore, understanding landscape connectivity is vital for effective species conservation. e snow leopard is endemic to mountainous areas of central Asia and occurs within 12 countries. We assess potential connectivity across the species’ range to highlight corridors for dispersal and genetic flow between populations, prioritizing research and conservation action for this wide-ranging, endangered top-predator. We used resistant kernel modeling to assess snow leopard population connectivity across its global range. We developed an expert-based resistance surface that predicted cost of movement as functions of topographical complexity and land cover. e distribution of individuals was simulated as a uniform density of points throughout the currently accepted global range.

RUNNING HEAD: LYNX M2 AND IRREVERSIBILE EVOLUTION Abstract There is a longstanding interest in whether the loss of complex characters is reversible (so-called “Dollo’s law”). Reevolution has been suggested for numerous traits but among the first was Kurtén (1963), who proposed that the presence of the second lower molar (M2) of the Eurasian lynx (Lynx lynx) was a violation of Dollo’s law because all other Felids lack M2. While an early and often cited example for the reevolution of a complex trait, Kurtén (1963) and Werdelin (1987) used an ad hoc parsimony argument to support their proposition that M2 reevolved in Eurasian lynx. Here I revisit the evidence that M2 reevolved in Eurasian lynx using explicit parsimony and maximum likelihood models of character evolution and find strong evidence that Kurtén (1963) and Werdelin (1987) were correct – M2 reevolved in Eurasian lynx.

  • The Threatening but Unpredictable Sarcoptes Scabiei: First Deadly Outbreak in the Himalayan Lynx, Lynx Lynx Isabellinus, from Pa
    Hameed et al. Parasites & Vectors (2016) 9:402 DOI 10.1186/s13071-016-1685-0 LETTER TO THE EDITOR Open Access The threatening but unpredictable Sarcoptes scabiei: first deadly outbreak in the Himalayan lynx, Lynx lynx isabellinus, from Pakistan Khalid Hameed1,2, Samer Angelone-Alasaad3,4* , Jaffar Ud Din5,6, Muhammad Ali Nawaz7 and Luca Rossi8 Abstract Although neglected, the mite Sarcoptes scabiei is an unpredictable emerging parasite, threatening human and animal health globally. In this paper we report the first fatal outbreak of sarcoptic mange in the endangered Himalayan lynx (Lynx lynx isabellinus) from Pakistan. A 10-year-old male Himalayan lynx was found in a miserable condition with severe crusted lesions in Chitral District, and immediately died. Post-mortem examination determined high S. scabiei density (1309 mites/cm2 skin). It is most probably a genuine emergence, resulting from a new incidence due to the host-taxon derived or prey-to-predator cross-infestation hypotheses, and less probable to be apparent emergence resulting from increased infection in the Himalayan lynx population. This is an alarming situation for the conservation of this already threatened population, which demands surveillance for early detection and eventually rescue and treatment of the affected Himalayan lynx. Keywords: Sarcoptes scabiei, Lynx lynx isabellinus, Human-lynx conflict, Chitral District, Pakistan, Neglected parasite, Emerging disease Letter to the editor threatened. The last population assessment reported Although affecting more than 100 species of mammals sporadic occurrence with a minimum of six individuals worldwide [1, 2], the epidemiology of Sarcoptes scabiei is [7]. The prime threats to the existence of the Himalayan still not well understood, with differences between lynx are retaliatory killing because of human-lynx con- locations and host species [3].

  • Periodic Review of Animal Species Included in the CITES Appendices
    AC25 Doc. 15.2.2 CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA ___________________ Twenty-fifth meeting of the Animals Committee Geneva (Switzerland), 18-22 July 2011 Periodic review of animal species included in the CITES Appendices Periodic review of Felidae REVIEW OF LYNX SPECIES UNDER THE PERIODIC REVIEW OF SPECIES INCLUDED IN THE CITES APPENDICES [RESOLUTION CONF. 11.1 (REV. COP15), RESOLUTION CONF. 14.8, AND DECISION 13.93 (REV. COP15)] This document has been submitted by the United States of America*. INTRODUCTION At the thirteenth meeting of the Conference of the Parties (Bangkok, October 2004), the United States of America had submitted a proposal (CoP13 Prop. 5) to remove Lynx rufus (bobcat) from Appendix II. At CoP13, the United States consulted with other Parties on the proposal. Some Parties, especially the Member States of the European Community, expressed concerns about potential problems with control of trade in other Lynx spp. due to their similarity of appearance to Lynx rufus. Mexico also expressed the need to further evaluate the status of Lynx rufus within its borders. However, many Parties expressed support for a review of the listing of the Felidae because they believed that the listing of some species in the family does not accurately reflect their current biological and trade status. They also agreed that the listings of species due to look-alike concerns should be reviewed to determine if current identification techniques, trade controls, and other factors still require them to be listed because the species have been listed without a substantial review since CoP2 in 1977.

  • Management of Large Carnivores in the Alps
    BRIEFING Requested by the ENVI committee Overcoming barriers – management of large carnivores in the Alps KEY FINDINGS After centuries of intensive hunting large carnivores like brown bears, Eurasian lynx and wolves are now recovering in many areas of Europe. This work deals with large carnivore populations in the French Alps focusing on wolf and gives information on the recent population status, management, legal frameworks and recommendations for habitat protection and coexistence of humans and large carnivores. The occurrence of wolves in France is limited to the Western Central Alps. In 2017 52 packs (360 individuals) were monitored. The Western Alpine population is of Italian origin, and migration moving from the Apennines to the Alpine population is still underway. Wolf populations are still far from being accepted by local farmers and livestock breeders, and conflicts with hunters are also reported. A French wolf plan exists. The actions listed in the wolf plan are based on livestock protection and compensations. The principles of “tir de défense” (removal of stock raiding individuals) and “tir de prélèvement” (a yearly defined number of individuals are removed) are applied. The goal is to reduce predation and keep or increase wolf populations and maintain them at favourable conservation status. Lynx is present in France in the Jura, the Vosges-Palatinian region and in the Alps. The alpine population originates from the Carpathians, where the nearest autochthonous population can be found. In 2016 100 individuals lived in France, and a small population of around 30 individuals has settled in the North of the French Alps (Savoie). For the lynx no management plan exists.

  • Lynx Reintroduction JUNE 2014
    COLORADO PARKS & WILDLIFE Lynx Reintroduction JUNE 2014 Colorado’s Lynx Reintroduction Success A year before the U.S. Fish and Wildlife Service listed the lynx as a threatened species in 2000, the Colorado Division of Wildlife (now Colorado Parks and Wildlife - CPW) started reintroducing lynx to the state. Over the next seven years, CPW brought 218 lynx to Colorado and established a self-sustaining population. Lynx Background Lynx, (Lynx canadensis), are large members of the cat family with short tails and distinctive black ear tufts that are as large as the animal’s ear. Often confused with the bobcat (Lynx rufus), lynx have large feet and grayish coats without spots. Lynx tails are entirely black while the underside of bobcat tails is white. Lynx are solitary by nature and inhabit dense high altitude forests or willow-rich mountain stream corridors. The huge feet enable lynx to easily traverse deep winter snowfields in search of their preferred prey - snowshoe hare (Lepus americas). Lynx weigh 20-to-30 pounds and have a home range of up to 20 square miles Lynx are native to North America, historically inhabiting forests in 25 states, including Colorado. Lynx populations dropped steadily in the United States throughout the 1900s due to unregulated trapping, widespread predator poisoning and habitat loss due to logging and other development. History of Lynx in Colorado Lynx were established in Colorado’s high elevation forests prior to European settlement. In the early 1800s, commercial trappers sought the thick fur, which sold for premium prices in the international market. The lynx population in Colorado dropped rapidly in the late 1800s and early 1900s.
