Chapter
Living American marsupials comprise ca. 130 species included in three orders, extending from northern North America (Canada–US border) to southern Argentina (48° South), with a higher richness in tropical and subtropical areas of Central and South America, declining with increasing latitude. The influence of climate throughout their evolution resul...

La reciente propuesta de una nueva era geológica denominada Antropoceno a partir del año 1950, en donde el Homo sapiens es el principal actor le ha dado a las ciencias humanas y sociales la posibilidad de discutir y contribuir en su adecuada definición, más allá del golden spike que se pueda emplear. Nuestro interés es mostrar que estamos frente a...
Chapter
Employment is a largely neglected indirect benefit in ecosystem services (ES) assessments, despite its relevance in countries with abundant rural landscapes. We present an analysis of the spatial connections between landscape composition (as a proxy of natural capital and ES) and employment level as measured by the number of people employed in tour...
Article
The distributional range of South American marsupials is the response to evolutionary history, geology and climate, resulting in a chorology characteristic of each taxon. We integrated information for each species using the global conservation status given by the International Union for Conservation of Nature (IUCN), plus the taxonomic singularity,...
Article
Eligmodontia morgani and E. typus are two small (<25 g) sigmodontine rodents that live in dry areas of southern Argentina. The species are very difficult to distinguish in the field, so their geographical delimitation has always been the subject of controversy. In this work we used sampling sites where each species has been previously identified by...

We develop a mathematical model of extinction and coexistence in a generic predator-prey ecosystem composed of two herbivores in asymmetrical competition and a hunter exerting a predatory pressure on both species. With the aim of representing the satiety of hunters when preys are overabundant, we introduce for the predation behavior a dependence on...

To understand the process of community assembly ecologists searched for nonrandom patterns in local coexistence, making extensive use of species presence-absence data and null models. We tested the assembly rule proposed by Fox (1987) using data from small mammal assemblages across a strong environmental gradient in Patagonia. Patagonian small-mamm...

Some ecologists have been skeptics about the use of owl pellets to estimate small mammal's fauna. This is due to the assumptions required by this method: (a) that owls hunt at random, and (b) that pellets represent a random sample from the environment. We performed statistical analysis to test these assumptions and to assess the effectiveness of Ba...

We analyze a mathematical model of a simple trophic web with two herbivores and one predator. The studied scenarios represent a common practice in the steppes of Argentine Patagonia, where livestock are raised in a semi-wild state, either on the open range or enclosed, coexisting with competitors and predators. We perform numerical simulations of m...

Sheep rearing is the main productive activity in Patagonian rangelands, where guanacos are the only native ungulate. Ranchers perceive a decrease in range carrying capacity as guanaco numbers increase, therefore guanaco conservation within private lands becomes a considerable challenge. This issue is particularly evident in the World Natural Herita...
