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 behaviour of the banded pine weevil, Pissodes castaneus (Coleoptera: Curculionidae)
(Wiley, 2023-08)Pissodes castaneus represents an emerging pest species for Pinus spp. production in Latin America. This species attacks all the cultivated pine species in Patagonia Argentina causing wood damage and tree death. The objectives ... -
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 ... -
How to succeed in implementing community-based breeding programs: Lessons from the field in Eastern and Southern Africa
(Frontiers Media, 2023-03)Breeding programs involving either centralized nucleus schemes and/or importation of exotic germplasm for crossbreeding were not successful and sustainable in most Africa countries. Community-based breeding programs (CBBPs) ... -
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 ... -
Identification and molecular characterization of Orf virus in Argentina
(Springer, 2015-06)Orf virus (ORFV) is the etiological agent of contagious ecthyma (CE), a pustular dermatitis of sheep and goats. Outbreaks of ORFV have been observed in all geographical regions of the world, including Argentina. The origin ... -
Identification of beef production farms in the Pampas and Campos area that stand out in economic and environmental performance
(Elsevier, 2018-06)Worldwide, native grasslands are being converted to non-native pastures and cropland. This process threatens local grassland biomes as well as the livelihoods of farm families that utilize these grasslands. In the Río ... -
