The concentration of people living in small areas has increased in the last decade, with more than half of the world's population living in cities. This is particularly true for Latin America, a region with no particular high contribution to the world total population, but hosts several large cities. The increase in urbanization causes several thre...

Deer species can cause serious damages to trees through browsing and antler rubbing, and these impacts can generate significant economic losses. As a tool to minimize damages to trees by deer, repellents based on odor, visual and/or taste stimulus have been developed and tested. Repellents vary greatly in terms of costs, forms of use, duration, and...

• Surplus killing (i.e. predation in which predators kill more prey than necessary to satiate their hunger) appears to be widespread in carnivores and has the potential to exacerbate human–carnivore conflict. Nevertheless, little is known about the frequency of surplus killing or about its impact on livestock. • We review the information available...

Livestock predation is one of the major causes of conflicts between humans and pumas (Puma concolor). Using data from interviews to ranchers and kill-site inspections, we characterized puma-livestock conflicts in Villarino and Patagones counties of central Argentinean rangelands. Depredation was considered the major cause of livestock losses, and p...

Project
En Argentina, de las 11 especies de felinos presentes en el territorio, seis están categorizadas como “Vulnerable” o “En Peligro”. Las principales amenazas que enfrentan son de origen antrópico, principalmente: la transformación de los hábitats, la persecución y caza, tanto directa como de sus presas naturales. En dicho país, Chubut se encuentra entre las provincias con mayor proporción de tierras degradadas y afectadas por la erosión eólica e hídrica. Es por esto, que la presencia de áreas protegidas resulta ser de gran importancia para las especies silvestres que habitan este territorio. El Parque Nacional Los Alerces (PNLA) es el área protegida de mayor relevancia en cuanto a superficie abarcada en el noroeste de la provincia de Chubut. Tres de las cuatro especies de felinos registradas para esta provincia se encuentran dentro del PNLA: el puma Puma concolor, el gato montés Leopardus geoffroyi y el gato huiña Leopardus guigna. Si bien en Argentina existe información ecológica sobre dos de estas especies (L. geoffroyi y P. concolor) hay escasa información disponible sobre la especie más pequeña. El objetivo de este proyecto es estudiar la ecología espacio-temporal de estas tres especies de felinos dentro del PNLA. Para alcanzarlo, se utilizarán trampeos fotográficos. Se analizará el patrón de ocupación y actividad de cada especie y entre las mismas. La información recolectada permitirá ampliar los conocimientos ecológicos de estas especies, como también aportar pautas para planes de gestión y manejo en las Áreas Protegidas en esta región del noroeste patagónico.
Project
One of the main threats to the biodiversity of our planet is the transformation of natural habitats, a phenomenon that can reduce landscape functional connectivity. Low functional connectivity can result in isolated populations with increased risk of extinction, so, the identification of landscapes with high functional connectivity is a priority for conservation planning. Connectivity can be affected not only by the spatial distribution/configuration of natural habitats but also by the presence/absence of human-induced-features: light pollution and fencing. In Switzerland, wild boar and red deer play key roles in ecosystems, as well as generate negative impacts to human resources. We propose to study how human-induced-features affects the functional connectivity of wild boar and red deer in Switzerland and define risk areas for crop and forest damage and potential spreading of diseases. Using geographic information system and statistic tools, we will model the effect of “hidden” barriers (light pollution and fencing) in connectivity models of wild boar and red deer and built a risks’ area maps. Additionally, we will delineate guidelines to incorporate in national management plans to incorporate in the daily work of wildlife conservation stakeholders. The relevance of this project is that all the cantonal administrations will be able to assess the quality of their corridor network in order to maintain or improve its functionality and to localize the potential risks of two large species in an area characterized mainly by agriculture: the Swiss Plateau.
Project
In the Lower Delta of Paraná producers report damage caused by marsh deer on commercial plantations. We proposed to evaluate different stimuli to attract/repel this species on forest plantations, in order to develop a divergent stimulus system "push-pull". Stimuli of repulsion and attraction will be tested on willow, poplar and/or wicker plantations with damage caused by deer. This design is presented to reduce levels of damage, decreasing the human impact on this species and facilitating the coexistence of this deer with forestry activities.
