Information on the extent of bushmeat hunting is needed to assess the likely impact on hunted species, to provide information on the opportunity cost to local people of conservation, and to judge the efficacy of interventions at reducing pressure. However, where hunting is illegal, or socially unacceptable, respondents may not answer honestly to direct questions about hunting or consumption of bushmeat. We adapted a specialized method for investigating sensitive behaviours (the randomized response technique, RRT) and questioned 1,851 people in Madagascar about their consumption of six species, using either RRT or direct questions. For most species at most sites RRT and direct questions returned similar estimates of the proportion of the population who had consumed bushmeat in the previous year. However, RRT resulted in significantly higher estimates of bushmeat consumption in communities surrounding a protected area, where conservation activities made such questions sensitive. RRT has been predominately used in Europe and the USA; we demonstrate that it can provide a valuable approach for studying rule-breaking among people with poor literacy in low income countries. Between 12 and 33% of people across our sites had eaten brown lemur (Eulemur spp.), and 12–29% had eaten sifaka (Propithecus spp.) in the previous year. These results add to the growing body of evidence that hunting of protected species in Madagascar is a serious problem requiring urgent action. Conservation interventions to tackle bushmeat hunting will make questions about hunting or consumption more sensitive, increasing the need for researchers to use appropriate approaches for asking sensitive questions.

Camera traps are standard tools for assessing populations of medium–large terrestrial mammals, particularly for rare, elusive or cryptic species, yet few researchers have attempted to employ camera traps to document rare primates in arboreal settings. We examined different arboreal camera-trap techniques to document the Critically Endangered greater bamboo lemur Prolemur simus in Madagascar. We documented P. simus at two sites, confirming presence at one site. Most species, including 86% of all lemur occurrences, were documented in low light conditions (c. < 105 lux). Our study suggests that camera traps can be effective in validating unconfirmed sightings of rare or secretive primate species. We recommend that future work with cameras in arboreal settings considers seasonal activity patterns, targets sites with high food densities, uses local knowledge, and utilizes available techniques (e.g. traditional trapping techniques) and landscape topography to concentrate animal movement (e.g. steep slopes or ridge lines).

A main concern of farmers worldwide is how to reduce crop losses to wildlife. Some potentially lethal crop protection methods are non-selective. It is important to understand the impact of such methods on species of conservation concern. Uganda has important populations of Endangered eastern chimpanzees Pan troglodytes schweinfurthii. Farmers sometimes use large metal mantraps to guard their fields against crop-raiding wildlife, particularly baboons Papio anubis and wild pigs Potamochoerus sp.. Chimpanzees that range onto farmland also step in these illegal devices and without rapid veterinary invention face severe injury or eventual death. Unlike inadvertent snaring of great apes in African forests, the problem of mantraps in forest–farm ecotones has received little attention. We report 10 cases of entrapped chimpanzees in the cultivated landscape surrounding Uganda's Budongo Forest during 2007–2011, undoubtedly only a portion of the actual number of cases. Mantraps currently present a substantial threat to ape populations in this important conservation landscape. Our data underscore the need for conservation programmes to consider the techniques used by rural farmers to protect their livelihoods from wild animals.

The emerging commercial farmers in Namibia represent a new category of farmer that has entered the freehold farming sector since Namibia's independence in 1990. Several assessments of agricultural training needs have been carried out with these farmers but the issue of human–carnivore conflict has not yet been addressed. This study investigated one of the key components driving human–carnivore conflict, namely the attitudes of these farmers towards carnivores and how this affects the level of conflict and carnivore removal. We observed that the attitudes of these farmers are similar to farmers elsewhere. In general, farmers reported high levels of human–carnivore conflict. Many farmers perceived that they had a carnivore problem when sighting a carnivore or its tracks, even in the absence of verified carnivore depredation. Such sightings were a powerful incentive to prompt farmers to want to take action by removing carnivores, often believed to be the only way to resolve human–carnivore conflict. Nonetheless, our study showed that farmers who understood that carnivores play an ecological role had a more favourable attitude and were less likely to want all carnivores removed. We found that negative attitudes towards carnivores and loss of livestock, especially of small stock, predicted actual levels of human–carnivore conflict. Goat losses additionally predicted actual carnivore removals. We discuss the implications of our findings in relation to the activities of support structures for emerging commercial farmers in Namibia.

Human intervention is the main cause of the decline of the Critically Endangered European mink Mustela lutreola. In this study we analysed the main causes of direct human-caused mortality of the species in Spain. A total of 47 mortality records were obtained for the period 1950–1989, and 145 for 1990–2008. There was temporal variation in the cause of death, with trapping and shooting being the most common causes of mortality in 1950–1989 and road-kills in 1990–2008. In the case of road-kills there was variation related to road type. Males were more affected by road-kills than females, especially during the mating season when they range more widely. Our results indicate that there has been a change in human social behaviour and in people's awareness of the species, with a reduction in European mink captured and shot but an increase in mortality on roads.
