(Facultad de Agronomía, Universidad de Buenos Aires, 2012-03)La plantación de pino en Patagonia ha aumentado en las últimas décadas, y es escaso el conocimiento de su impacto sobre la biodiversidad, particularmente sobre especies de altos requerimientos de hábitat. Mediante trampas ... -
Yeast and yeast‐like fungi associated with dry indehiscent fruits of Nothofagus nervosa in Patagonia, Argentina
(Oxford Academic Press, 2012-04)Nothofagus nervosa (Raulí) is a native tree species that yields valuable timber. It was overexploited in the past and is currently included in domestication and conservation programs. Several research programs have focused ... -
Habitat use by carnivores at different spatial scales in a plantation forest landscape in Patagonia, Argentina
(Elsevier, 2012-04)Forest plantations are an increasingly important source of industrial wood around the world, and the design and management of plantations can greatly influence the relationship with wildlife. The aim of this study was to ... -
Identification of Corynebacterium pseudotuberculosis from sheep by PCR-restriction analysis using the RNA polymerase β-subunit gene (rpoB)
(Elsevier, 2012-04)Caseous lymphadenitis, caused by Corynebacterium pseudotuberculosis, has a high prevalence in many regions of the world, including Argentina and Brazil. A polymerase chain reaction–restriction fragment length polymorphism ... -
Cashmere quality of Raeini goats kept by nomads in Iran
(2012-05)The income of the nomads in Kerman Province depends mainly on Raeini goats that produce meat, milk and cashmere. This paper assesses the cashmere quality and its variation in Raeini herds to determine the scope for ... -
Patch choice from a distance and use of habitat information during foraging by the parasitoid Ibalia leucospoides
(2012-06)1. In environments in which resources are distributed heterogeneously, patch choice and the length of time spent on a patch by foragers are subject to strong selective pressures. This is particularly true for parasitoids ... -
La conservación de la biodiversidad en el marco del Ordenamiento Territorial
(CIFOT, 2012-06)Esta propuesta está orientada a enfatizar la importancia de la conservación del ambiente natural y su consideración adecuada en el ámbito de la planificación territorial. La prioridad que se le otorgue a cada componente ... -
Food and Host Searching Decisions Made by Ibalia leucospoides (Hymenoptera: Ibaliidae), a Parasitoid of Sirex noctilio (Hymenoptera:Siricidae)
(2012-07)During their adult life, parasitoids—insects that lay eggs in or on other arthropods eventually killing them- spend a significant proportion of their lifetime searching for hosts, this behavior will determine their future ... -
Genetic variation in seedling water-use efficiency of Patagonian Cypress populations from contrasting precipitation regimes assessed through carbon isotope discrimination
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), (España), 2012-07-20)Water-use efficiency (WUE) is a physiological parameter that plays a significant role in the evolutionary dynamics of many forest tree species. It can be estimated indirectly through carbon isotope discrimination (Δ). In ... -
