Wild dogs at stake: deforestation threatens the only Amazon endemic canid, the short-eared dog (Atelocynus microtis)

The persistent high deforestation rate and fragmentation of the Amazon forests are the main threats to their biodiversity. To anticipate and mitigate these threats, it is important to understand and predict how species respond to the rapidly changing landscape. The short-eared dog Atelocynus microtis is the only Amazon-endemic canid and one of the most understudied wild dogs worldwide. We investigated short-eared dog habitat associations on two spatial scales. First, we used the largest record database ever compiled for short-eared dogs in combination with species distribution models to map species habitat suitability, estimate its distribution range and predict shifts in species distribution in response to predicted deforestation across the entire Amazon (regional scale). Second, we used systematic camera trap surveys and occupancy models to investigate how forest cover and forest fragmentation affect the space use of this species in the Southern Brazilian Amazon (local scale). Species distribution models suggested that the short-eared dog potentially occurs over an extensive and continuous area, through most of the Amazon region south of the Amazon River. However, approximately 30% of the short-eared dog's current distribution is expected to be lost or suffer sharp declines in habitat suitability by 2027 (within three generations) due to forest loss. This proportion might reach 40% of the species distribution in unprotected areas and exceed 60% in some interfluves (i.e. portions of land separated by large rivers) of the Amazon basin. Our local-scale analysis indicated that the presence of forest positively affected short-eared dog space use, while the density of forest edges had a negative effect. Beyond shedding light on the ecology of the short-eared dog and refining its distribution range, our results stress that forest loss poses a serious threat to the conservation of the species in a short time frame. Hence, we propose a re-assessment of the short-eared dog's current IUCN Red List status (Near Threatened) based on findings presented here. Our study exemplifies how data can be integrated across sources and modelling procedures to improve our knowledge of relatively understudied species

Survey of domestic accidents in the elderly in the Province of Genoa (northern Italy)

INTRODUCTION: Accidents in the home are a major public health issue in most industrialised countries, as they are a frequent cause of injury and death. Moreover, since a considerable portion of such accidents involve elderly people, it is important to assess their social impact in this population. In Italy, the available data indicate that well over 3 million people per year suffer accidents in the home, and that this number is rising. The aim of the present study was to evaluate the number, characteristics and causes of domestic accidents among the elderly. MATERIALS AND METHODS: The study population was made up of subjects of both sexes aged between 65 and 92 years admitted to first aid units and emergency departments of hospitals in Genoa. The investigation was conducted by means of an ad hoc questionnaire designed to record the circumstances of the accident, the functional capacity of the subject involved, any risky behaviour enacted and the safety profile of the subject's home. RESULTS: The study enrolled 111 voluntary participants: 62 women and 49 men. At the time of the accident, subjects were engaged in the following activities: housework (36.9%) "rest" (14.5%), ablutions (10%), gardening (9%), leisure activities (8.1%), eating and drinking (2.7%). The most common injuries were bruises (39.6%), followed by fractures (23.4%) and cuts (23.4%); the frequency of other, some time more severe injures (burns, poisoning, asphyxia, crush injuries, etc.) was,fortunately, very low. Anyway, taking into account their consequences, their surveillance and prevention is very important. Most subjects were deemed to be in good health and, in 76% of cases, the safety profile of their houses proved to be satisfactory. DISCUSSION AND CONCLUSIONS: The data collected during this survey are in line with those yielded by national and international studies. They show that the elderly are very vulnerable to domestic accidents and that, even in the event of only slight injury, the management of elderly victims requires a strong organisational commitment on the part of relatives and considerable financial resources for healthcare services. Falling proved to be the main cause of injury. Clearly, efforts to reduce the cost of accidents in the home should aim to implement preventive intervention among elderly people, since the elderly population is destined to grow as a result of increasing life expectancy. In particular, preventive action should focus on reducing the incidence of falls by eliminating risk-related structural features in domestic settings as far as possible and by raising public awareness of the problem through health education campaigns
