Coexistence between species with similar ecological niches implies must segregate along one or more niche axes to survive. Space, time, and trophic resources are regarded as the principal upon which segregate. We examined segregation these determine mechanisms underlying coexistence two main predators, puma (Puma concolor) culpeo foxes (Lycalopex culpaeus) in Andes of Central Chile. used occupancy modeling examine space use overlap, Kernel Density Estimation temporal activity patterns...
OBJECTIVE: To study the risk of Trypanosoma cruzi domestic transmission using an entomological index and to explore its relationship with household's characteristics cultural aspects. METHODS: There were studied 158 households in endemic area Argentina. Each household was classified according indicator (number risky bites/human). A questionnaire administered evaluate factors among householders. RESULTS: Infested showed a wide range values (0 5 bites/human) skewed distribution, high frequency...
AbstractWe use published zooarchaeological evidence to discuss the various hypotheses concerning past distribution of huemuls in Patagonia, southern South America. We then these data evaluate interactions between this cervid and hunter-gatherers during Holocene. The record shows that huemul mainly inhabited forested forest–steppe ecotonal environments Huemul were hunted exceptional circumstances early occupation Patagonia. Its presence Patagonia increases after 9500 BP is more frequent 2200...
Ecologically based rodent management strategies are arising as a sustainable approach to control, allowing us preserve biodiversity while safeguarding human economic activities. Despite predator signals being known generally repel rodents, few field-based studies have compared the behavioral effects of several predators on different prey species, especially in Neotropical ecosystems. Here, we used camera traps study behavior species native Chilean temperate forest (Abrothrix spp.,...
En este artículo se discuten algunos aspectos teóricos y metodológicos de la zooarqueología tafonomía en relación con el desarrollo estas disciplinas Sudamérica. Particularmente, tratan cuestiones relacionadas las escalas análisis, aproximaciones teórico-metodológicas sobre papel los procesos tafonómicos comportamiento humano, interacción entre zooarqueología. Estos temas son abordados marco del estado actual contexto particularidades faunas Neotropicales.
En este ensayo buscamos contribuir a los debates actuales sobre el Antropoceno, poniendo en diálogo nuestras reflexiones con abordajes que proponen tres trabajos seleccionados por comité editorial. Revisamos estos considerando cómo se relacionan la perspectiva demarcatoria, predominante geología y de arqueología no puede quedar ausente. También nos focalizamos las escalas temporales espaciales plantean, enfoques teóricos epistemológicos propuestos papel jugar frente un concepto pretende...
Background: Hepatic encephalopathy (HE) is a common complication of cirrhosis associated with reduced survival. The presence high-flux spontaneous porto-systemic shunts can induce HE even in patients preserved liver function.
