Based on frames of reference built out of actualistic taphonomic studies, it is possible to identify the type of raptor bird involved in the fossil record by categorising the degree of digestive corrosion, as well as the degree of breakage, in microvertebrate skeletal elements.

Carnivorous mammals generate specific prey bone accumulations, including scats containing ingested remains, namely composed by microvertebrates. Here we present an actualistic study of the micromammals consumed by the Achala fox (Lycalopex culpaeus smithersi), endemic to the Pampa de Achala plateau (2000 masl average, 31º36'S, 64º51'W) in the mount...

Contribuir a la generación de un modelo de análisis multiproxy de heces y egagrópilas actuales para la interpretación del registro fósil en el valle de El Bolsón.

We present the first actualistic study of the rodents consumed by the South American fox Lycalopex culpaeus smithersi (Achala culpeo fox), a subspecies of the culpeo fox that is endemic to the highlands of central Argentina. We provide a taphonomic characterization of this canid based on digested micromammal bones, and compare it to other carnivore...

The taphonomy of mammalian carnivores is relevant to the interpretation of the fossil record, as these agents may accumulate, transport, modify and destroy faunal assemblages, including those associated to anthropic remains. Carnivore activity can not only delete information by biasing faunal accumulations, but also provide relevant palaeoecologica...

Ríos, bañados, lagunas y efímeros charcos son lugares preciados por los animales, especialmente en la áridez de la ecorregión del Monte. También los llamados "tanques australianos" son fuentes de agua, pero pueden transformarse en verdaderas trampas mortales. Se están implementando algunas soluciones.

Aim Understanding the mechanisms that drive phenotypic divergence along climatic gradients is a long‐standing goal of biogeography. To fulfil this objective, we tested if neutral and/or adaptive effects drive phenotypic diversification. We quantified the effects of neutral evolution and natural selection on morphological variability of a well‐suite...

A total of 111 samples (43 faeces and 79 gastrointestinal tracts) of 14 wild carnivore species from 12 Argentine provinces were analyzed. Helminth eggs were identified in 73% of the faecal samples and adult worms were recovered from 81% of the gastrointestinal tracts. We found 19 helminth species. Among the most frequent findings were parasites of...

RESUMEN. Los predadores tope son las especies más afectadas por las alteraciones en las redes tróficas de origen antrópico. Examinamos la dieta de dos carnívoros simpátricos (puma Puma concolor y zorro colorado Pseudalopex culpaeus smithersi) y evaluamos la importancia de los roedores en términos energéticos, ya que los métodos tradicionales tiende...

This study presents the first data on the diet of the puma ( Puma concolor ) and an endemic culpeo fox ( Pseudalopex culpaeus smithersi ) in the high mountains of central Argentina, based on scat analysis. Trophic interactions of both carnivores were examined from 2003 to 2008 inside a protected area after livestock removal. A total of 604 scats we...

En el año 2000 se realizo un estudio sobre los efectos directos e indirectos del ganado domestico sobre la ecología trófica del zorro colorado endémico de Pampa de Achala (Pseudalopex culpaeus smithersi) evaluando su dieta, disponibilidad y selección de presas en dos sitios con diferente abundancia de ganado. El estudio fue llevado a cabo en el Par...

Understand the factors that lead morphological differentiation is a central question in evolutionary biology. The extraordinary latitudinal distribution of the fox Lycalopex culpaeus makes it a model species to investigate the causes of phenotypic divergence. We analyzed the morphological differentiation of the species from genetic analyzes using m...

Evaluamos la ocurrencia de puma Puma concolor y zorro colorado Pseudalopex culpaeus smithersi en relación a la presencia humana, características del paisaje y a la creación de un parque nacional donde la abundancia de ganado doméstico fue reducida y la caza prohibida en las Sierras Grandes de Córdoba. Se recorrieron a pie transectas (5×1000m; 14 de...

Se analizó la dieta anual del zorro colorado Pseudalopex culpaeus smithersi, endémico de Pampa de Achala (Provincia de Córdoba), y se evaluaron las diferencias tróficas entre dos áreas con distinta carga ganadera. Se recolectaron 370 heces dentro del Parque Nacional Quebrada del Condorito (parque), donde el ganado fue removido casi en su totalidad,...

At present, the ecology of carnivore populations is largely shaped by human intervention. In much of Argentina, the role of puma and culpeo fox has been changed due to human-induced changes in prey base and the availability of suitable habitat to survive, among others. The objective of this thesis was to determine how induced changes in the environ...

The creation of protected areas does not always satisfy the area requirements of large carnivores, and often do not even possess a complete assemblage of native preys, bringing large carnivores in conflict with humans due to livestock predation. In the mountains of Central Argentina, for over 4 centuries, the puma coexists with livestock ranching a...

We present the 1st data on the diet of the Andean mountain cat (Leopardus jacobitus), and the 1st on the colocolo (Leopardus colocolo) and the culpeo (Lycalopex culpaeus) in high-altitude deserts of northern Argentina, based on fecal analysis. Feces of Andean mountain cats and colocolos were distinguished by DNA analysis. The Andean mountain cat (n...

Existen numerosos conflictos por ataques de carnívoros al ganado adyacente a áreas protegidas. Para brindar sugerencias de manejo, evaluamos dentro y fuera del Parque Nacional Monte León (PNML-Santa Cruz) densidades relativas de puma (Puma concolor) y zorro (Pseudalopex culpaeus) mediante transectas de conteos de signos y estaciones odoríferas, res...

Los carnívoros son considerados competidores con los humanos por el ataque de ganado domestico. Elaboramos un diagnostico del conflicto realizando encuestas a productores vecinos del Parque Nacional Quebrada del Condorito (PNQC), y analizamos la dieta de predadores a partir de heces en dos periodos (2003-2004). El 84% de los productores realiza cui...

Entre los mamíferos, el grupo de los predadores tope, está representado por especies clave para el ecosistema como reguladores de las poblaciones de herbívoros, disminuyendo la presión que éstos ejercen sobre la vegetación. En Pampa de Achala, y el Parque Nacional, los grandes predadores están representados por el puma (Puma concolor) y una subespe...

El gato de pajonal (Lynchailurus colocolo) y el zorro colorado (Pseudalopex culpaeus) tienen extensas distribuciones en Sudamérica que incluyen un amplio espectro de hábitats. Sin embargo, existe escasa información sobre ecología del gato de pajonal en cualquiera de sus hábitats nativos y, aunque el zorro colorado ha sido objeto de estudios en Chil...

ABSTRACT Livestock can affect the feeding ecology of carnivores either directly, by becoming potential prey, or indirectly, by modifying,selection of other prey. Selection of other prey is modified through the negative effects of livestock on food and cover, which reduces density and increases vulnerability of wild prey. Pseudalopex culpaeus smithe...

Pampa de Achala is has been the subject of very few studies, and particularly little research has been done on the mammals of the area. Pseudalopex culpaeus smithersi is an endemic subspecies of culpeo fox that is restricted to this area. In the fall and spring of 2000, density and biomass of potential prey species of the culpeo fox was estimated a...
