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 ... -
Habituation in mosquito larvae Aedes aegypti is context-specific
(The Company Biologists, 2021-06)Mosquito larvae live in water and perform a stereotyped escape response when a moving object projects its shadow on the surface, indicating potential risk of predation. Repeated presentations of the shadow induce a decrease ... -
Half a century of changes in the riverine landscape of Limay River: the origin of a riparian neoecosystem in Patagonia (Argentina)
(Springer, 2016-06)Our study aims to determine the dynamic that led to the spread of exotic Salicaceae on the Limay River floodplain and its implications in shaping the current neoecosystem. We used images obtained by the HRG sensor on board ... -
Halfway encounters: Meeting points of colonization routes among the southern beeches Nothofagus pumilio and N. antarctica
(2015-04)The Patagonian region is characterized by a complex biogeographic history, with evidence of deep phylogeographic breaks shared among species. Of particular interest to conservation is the nature of colonization and settlement ... -
Heritable variation in the survival of seedlings from Patagonian cypress marginal xeric populations coping with drought and extreme cold
(Springer, 2012-01)The rear edges of tree species have begun to be perceived as highly valuable for genetic resources conservation and management. In view of expected climatic changes, the responses of trees at their xeric limits may largely ... -
Una herramienta para monitorear sequías en regiones áridas y semiáridas de Patagonia Norte
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-08)La variabilidad ambiental es una característica de regiones pastoriles áridas y semiáridas, siendo la sequía uno de los principales problemas en sistemas ganaderos extensivos, con implicancias productivas y económicas tanto ... -
High genetic variation in marginal fragmented populations at extreme climatic conditions of the Patagonian Cypress Austrocedrus chilensis
(Elsevier, 2010-03)Knowledge about current patterns of genetic structure of populations together with the evolutionary history of a species helps to understand and predict the adaptation of populations to future climate change. We assayed ... -
Honeybees generalize among pollen scents from plants flowering in the same seasonal period
(The Company of Biologists, 2019-11)When honey bees (Apis mellifera) feed on flowers, they extend their proboscis to absorb the nectar, i.e. they perform the proboscis extension response (PER). The presence of pollen and/or nectar can be associated with ... -
Hormonal therapeutic strategy on the induction of accessory corpora lutea in relation to follicle size and on the increase of progesterone in sheep
(2018)We determined the effect of GnRH or hCG treatment on day 4 post-time artificial insemination (FTAI) onthe formation of accessory corpora lutea (acc-CL) and on the concentration of serum progesterone (P4)insheep. Multiparous ... -
Host genetics determines food preferences of the moth Perzelia arda (Lepidoptera: Depressariidae)
(Wiley, 2021-12)Genetic variation among host plants can influence herbivore behaviour and consequently their abundance, performance and environmental impact. In the Andean- Patagonian forest, the arboreal vegetation is dominated by species ... -
Host plant choice and effect of temperature on feeding behaviour of Perzelia arda (Lepidoptera: Depressariidae), a leaf-tying larva, on Nothofagaceae from the Andean Patagonian forest
(Wiley, 2021-08)Environmental temperature may cause changes in the physiology and feeding behaviour of herbivorous insects and, consequently, in the damage they can cause. In the Andean Patagonian forest, an eco-region dominated by trees ... -
Host selection by Ibalia leucospoides based on temporal variations of volatiles from the hosts’ fungal symbiont
(2016-12)Insect parasitoids locate hosts via reliable and predictable cues such as volatile emissions from hosts and/or host plants. For insects that depend on mutualistic organisms, such as many wood-boring insects, symbiont-derived ... -
Host-related volatile cues used by a parasitoid wasp during foraging for its woodboring host
(Wiley, 2018-12)Parasitoids relymainly on infochemicals to search for their herbivore hosts to oviposit on. Megarhyssa nortoni (Cresson) (Hymenoptera: Ichneumonidae) is a parasitoid of siricid wasp larvae which are concealed inside tree ... -
How does crop residue removal affect soil organic carbon and yield? A hierarchical analysis of management and environmental factors
(2015-10)The current advancement of the bioenergy sector along with the need for sustainable agricultural systems call for context-specific crop residue management options – implying variable degrees of removal – across climatic ... -
Human-carnivore interaction in a context of socio-productive crisis: Assessing smallholder strategies for reducing predation in North-west Patagonia, Argentina
(2018)Mitigating carnivore-livestock interaction is essential to ensuring the persistence of carnivores in landscapes dominated by livestock activity. Our aim was to explore, in the context of social and productive crises ... -
Identificación del origen genético de un rodal semillero implantado de Nothofagus obliqua a través del análisis de dos regiones inter-génicas de ADN de cloroplasto
(Ediciones INTA, 2021-04)En planes de forestación, tanto con fines productivos como de conservación, la correcta elección de la fuente de semilla para utilizar es un factor clave. El área productora de semilla (APS) “Trevelin” de Nothofagus obliqua ... -
