Lobo (2008) Factors affecting invasive species abundance: the Barbary ground squirrel on Fuerteventura Island, Spain. Zoological Studies 47(3): 268-281. We assessed the determinants of habitat selection by the Barbary ground squirrel (Atlantoxerus getulus) at Fuerteventura (Canary Is., Spain). We implemented general linear model (GLM) procedures to analyze the relationships between squirrel abundances and 4 kinds of variables related to the biological requirements of the species (environment, food resources, biotic interactions, and refuge/shelter). We performed a variance partitioning analysis between the most explicative categories to explore correlation patterns. The time of year and weather conditions of the census clearly influenced the number of individuals observed. Shelter variables were the best correlates of both the abundance of squirrels and the number of their scat. Although food resources were less important, the presence of certain plant species was correlated with squirrel abundance, while general environmental variables and interactions with other mammals did not affect its distribution. These results improve our understanding of the ecology and the establishment of this highly successful introduced species, providing basic knowledge for use with future management strategies in the Canarian Archipelago. -

Links Between Biodiversity Conservation, Livelihoods and Food Security: the Sustainable Use of Wild Species for Meat
Links between Biodiversity Conservation, L IUCN Species Survival Commission The IUCN Species Survival Commission The Species Survival Commission (SSC) is one of six volunteer commissions of IUCN – The World Conservation Union, a union of sovereign states, government agencies and non- governmental organisations. IUCN has three basic conservation objectives: to secure the conservation of nature, and especially of biological diversity, as an essential foundation for the Links between Biodiversity future; to ensure that where the earth’s natural resources are used this is done in a wise, equitable and sustainable way; and to guide the development of human communities towards ways of life that are both of good quality and in enduring harmony with other components of the Conservation, Livelihoods biosphere. Avolunteer network comprised of some 7,000 scientists, field researchers, government officials and Food Security and conservation leaders from nearly every country of the world, the SSC membership is an unmatched source of information about biological diversity and its conservation. As such, SSC members provide technical and scientific counsel for conservation projects throughout the world and serve as resources to governments, international conventions and conservation The sustainable use of organisations. wild species for meat SSC Occasional Papers cover a broad range of subjects including conservation of groups of species in a particular geographical region, wildlife trade issues, and proceedings of workshops. IUCN/SSC also publishes an Action Plan series that assesses the conservation status of species and their habitats, and specifies conservation priorities. The series is one of ivelihoods and F Sue Mainka and Mandar Trivedi the world’s most authoritative sources of species conservation information available to natural Editors resource managers, conservationists and government officials around the world. -
No Evidence for Proteolytic Venom Resistance in Southern African Ground Squirrels
1 No evidence for proteolytic venom resistance in southern African ground squirrels Molly A. Phillips, Jane M. Waterman, Pg Du Plessis, Martin Smit, and Nigel C. Bennett Abstract Many species that interact with venomous snakes show resistances to their venoms. The family Sciuridae has several North American members that harass venomous snakes and show proteolytic resistances in their sera. We examined sera collected from an African ground squirrel (Xerus inauris) against two sympatric venomous snakes (Bitis arietans and Naja annulifera) and found no support for proteolytic resistance. Our results add to our understanding of the risks in predator defense within the family Sciuridae. Keywords: Xerus inauris; Bitis arietans; Naja annulifera; Venom; Venom resistance; Predator-prey Animal venoms are a complex mixture of proteins and peptides that induce many destructive physiological effects for a variety of purposes, including prey capture (Fry et al., 2008; Jansa and Voss, 2011), digestion (Thomas and Pough, 1979), and defense (Kardong, 1982). The evolution of venom in snakes is thought to be a major factor leading to the radiation of over 2500 advanced snake species (Vidal, 2002). Some animals that interact with venomous snakes have physiological resistance to venom. As a predator, the Indian grey mongoose (Herpestes edwardsii) is resistant to the haemorrhagic effects caused by the venom of many snake species (Tomihara et al., 1990). California ground squirrels (Spermophilus (Otospermophilus) beecheyi) defend against snake predation by mobbing and have resistance against the proteolytic activity of the venom from northern Pacific rattlesnakes (Crotalus oreganus) (Biardi, 2000). The Cape ground squirrel (Xerus inauris) is a ground-dwelling sciurid that inhabits the arid regions of southern Africa (Skurski and Waterman, 2005). -

The 2008 IUCN Red Listings of the World's Small Carnivores
The 2008 IUCN red listings of the world’s small carnivores Jan SCHIPPER¹*, Michael HOFFMANN¹, J. W. DUCKWORTH² and James CONROY³ Abstract The global conservation status of all the world’s mammals was assessed for the 2008 IUCN Red List. Of the 165 species of small carni- vores recognised during the process, two are Extinct (EX), one is Critically Endangered (CR), ten are Endangered (EN), 22 Vulnerable (VU), ten Near Threatened (NT), 15 Data Deficient (DD) and 105 Least Concern. Thus, 22% of the species for which a category was assigned other than DD were assessed as threatened (i.e. CR, EN or VU), as against 25% for mammals as a whole. Among otters, seven (58%) of the 12 species for which a category was assigned were identified as threatened. This reflects their attachment to rivers and other waterbodies, and heavy trade-driven hunting. The IUCN Red List species accounts are living documents to be updated annually, and further information to refine listings is welcome.

Mensah Faculté des Sciences Agronomiques, Université d’Abomey-Calavi, 05 BP 1752 Cotonou (Akpakpa-Centre), Benin Corresponding author : A.E. Assogbadjo, e-mail : [email protected] ABSTRACT. Rodents are an important food source for villagers near the Lama forest reserve, located in the south of Benin between 6°55 - 7°00N and 2°04 - 2°12 E. This study was designed to look at the consumption of rodents as a food source combined with a survey of rodents sold in markets. Data was collected on : rodents species consumed, frequencies of consumption and food preferences. Some animals were captured in order to confirm the species. Rodents were a major part of diet included 10 species : grasscutter (Thryonomys swinderianus), giant rats (Criceto- mys gambianus), Gambian Sun-squirrel (Heliosciurus gambianus), crested porcupine (Hystrix cristata), ground squirrel (Xerus erythropus), grass rat (Arvicanthis niloticus), slender gerbil (Taterillus gracilis), Kempi’s gerbil (Tatera kempii), multimammate rats (Mastomys spp.) and grass mouse (Lemniscomys striatus venustus). On aver- age, young people and children consumed rodents 6 times per person per month. The preferences of local popula- tions were grasscutter and giant rats which were sold in local markets at relatively high prices US$8-10 and US$2-4 respectively. It is important to conduct further studies to look at the impact of this hunting on the rodent populations and to ensure sustainable harvesting. -
