Carnivore Species

The Nearctic and Neotropical realms converge in central Mexico, where many areas have not been adequately characterized. Our objective was to revise the distribution and conservation status of carnivores in the state of Puebla, central Mexico. Between September 2008 and January 2011, we conducted interviews and fieldwork on seven previously selected areas. We complemented our data with bibliographical research. We obtained 733 records for 21 species, representing 63% of the carnivores reported for Mexico. We expanded known ranges of three species: Ocelot (Leopardus pardalis), Bobcat (Lynx rufus), and Tropical Ringtail (Bassariscus sumichastrii). Fifty percent of the carnivore species we recorded in Puebla are considered under some risk category. We found that carnivores in our study area are vulnerable to hunting pressure, human-carnivore conflicts that result in lethal control practices, and extensive habitat loss.

The Impact

In this paper we use mathematical modelling to consider the broad advantages and disadvantages of fertility control over lethal control for bovine tuberculosis in badger populations. We use a deliberately simple model, attempting to capture only the key transmission processes. The model is parametrized with reference to the long–term Woodchester Park study. Estimates of mortality rate from this study suggest no significant extra mortality risk for animals with evidence of infection as indicated by the presence of anti- Mycobacterium bovis antibodies or M. bovis isolation. We find that large reductions in prevalence are sometimes the consequence of only moderate reductions in population numbers. If we assume that the act of control does not in itself affect transmission rates, then as far as eradication is concerned, both fertility control and mortality control operate through the same epidemiological mechanism, the removal of susceptibles: if one is in principle capable of keeping a population low enough to be infection free then so is the other. It is necessary to continue either form of control at regular intervals to maintain a constant level of infection in the long term. If control were to be stopped, return to precontrol levels of badger population and infection prevalence would be expected within a few years. Fertility control is less effective in reducing population density than lethal control since it can only act, at maximum, to remove one age cohort per year. It is also less effective in reducing transmission as it can only ever remove susceptibles, while lethal control also removes infectious badgers. However, if the social disturbance caused by lethal control does in fact increase contact rates for the remaining infectious badgers, the relative efficacies of the two strategies become a great deal less clear. While we have no quantitative data on the extent to which social perturbation does act to promote transmission, model simulations show that it is possible to develop plausible scenarios in which the lethal control may actually act to increase the absolute numbers of animals infected, while reducing the number of uninfected animals to very low numbers.

Ecological Thinking

Globally, the role of large predators is increasingly understood as essential for the restoration and maintenance of ecosystems. Consequently, predator conservation represents a paradigm shift in ecological thinking, yet the management of predators sets conflicting goals because of ongoing conflict with humans. This is exemplified on Fraser Island where dingoes come into conflict with tourists, and dingoes perceived to be dangerous are regularly culled. It is argued here that this new conservation paradigm premised on protecting predators in conjunction with conventional wildlife management can result in predator populations being held in a perpetual state of social disorder, exacerbating rather than alleviating conflict. We consider the intensity and frequency of lethal control and how this may impact upon predator social structures, healthy ecological function, stable breeding patterns and stable territoriality. The direct effects of management-induced psychological stress for the survivors of episodic culls are discussed, as well as the indirect flow-on effects of social dysfunction. A final consideration is the cyclical nature of lethal control, whereby conflict with humans results in culling which, in turn, gives rise to further social disruption and conflict. In part, our assessment is derived from official data collected in the course of the management of dingoes on Fraser Island. On this basis, and on the basis of the international literature available, we offer new insights, which may inform predator management more broadly.

Multiple Levels

SUMMARYDespite increasing support for conservation efforts, humans exert strong negative forces on nature and disagree over the management of these effects. Conflicts over conservation policy may reflect evolving opinions about how people ought to conserve species and whether to intervene in various processes. To understand public preferences for conservation in the USA, we measured support for various strategies in five case studies, where we pitted one species against another in simplified but realistic scenarios. Among our online convenience sample of 1040 participants, we found the majority of participants favoured habitat protection in all but one case, and there was little acceptance of lethal control across all cases. The results reveal that habitat protection preferences positively relate to considerations of moral principles and ecosystems and negatively relate to economic and practical considerations. Older, conservative and male participants were less likely to support habitat protection and more likely to support no action. The results suggest broad support for holistic nature conservation that benefits both people and nature and highlight areas where current wildlife management may not align with public preferences. Controversy may continue until wildlife management policies are consistent with societal values and address moral and ecosystem considerations at multiple levels.

Large wild carnivore predation on domestic livestock and the associated financial losses may increase efforts toward lethal control of carnivore populations. Livestock‐guarding dogs could provide an effective alternative to such lethal control by mitigating depredation losses. Although this information is available in North America, the cost‐effectiveness of guarding dogs has not been studied in other areas experiencing large carnivore depredation such as South Africa, where the socio‐economic context is very different from that of North America. We assessed the costs and benefits of 97 livestock‐guarding dogs working on 94 farms in South Africa between 2005 and 2011 by reviewing data collected from questionnaires on perceived depredation losses prior to and during guarding dog placement, rates of guarding dog behavioral problems, removals, and pre‐senile mortality.
