Exploring drivers and levels of technology adoption for ecological intensification of pastoral systems in north Patagonia drylands
(Elsevier, 2022-02)Although pastoral systems make a significant contribution to food security, they are also pointed out as being responsible for substantial environmental impact. Ecological intensification through process- rather than ... -
Evaluation of three different antigens in an indirect enzyme-linked immunoassay for the detection of antibodies against Brucella abortus SRB51 in vaccinated heifers
(Elsevier, 2009)The live attenuated Brucella abortus SRB51 (SRB51) is a partial O-chain-deprived mutant. The relative lack of the polysaccharide prevents it from inducing antibodies detectable by most of the serological tests used for the ... -
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 ... -
Effect of Drosophila suzukii on Blueberry VOC’s: Chemical Cues for a Pupal Parasitoid, Trichopria anastrephae
(Springer, 2021-07)Biocontrol agents such as parasitic wasps use long-range volatiles and host-associated cues from lower trophic levels to find their hosts. However, this chemical landscape may be altered by the invasion of exotic insect ... -
Socio‑cognitive constraints and opportunities for sustainable intensification in South Asia: insights from fuzzy cognitive mapping in coastal Bangladesh
(Springer, 2021-07)Appreciating and dealing with the plurality of farmers’ perceptions and their contextual knowledge and perspectives of the functioning and performance of their agroecosystems— in other words, their ‘mental models’—is central ... -
Alpha-mannosidosis caused by toxic plants in ruminants of Argentina
(Academia Brasileira de Ciencias, 2021)It is well known that several of the swainsonine-containing plant species found widespread around the world have a negative economic impact in each country. In Argentina, most of the information on the poisonous plant ... -
Maqui (Aristotelia chilensis [Mol.] Stuntz) morphological and phenolic traits associated with forests type and latitudinal gradient in natural populations of Patagonia Argentina
(Elsevier, 2021-12)Maqui (Aristotelia chilensis [Mol.] Stuntz) is a native berry of the Patagonia Andean forests, which has one of the highest antioxidant levels currently known. This biochemical characteristic strongly depends on the phenolic ... -
Landholders’ perceptions on legal reserves and agricultural intensification: Diversity and implications for forest conservation in the eastern Brazilian Amazon
(Elsevier, 2021)Forest conservation on privately owned lands is a cornerstone of the Brazilian environmental policy framework. Brazilian legislation requires that all farms in the country maintain and protect forest areas known as Legal ... -
The application of ecologically intensive principles to the systemic redesign of livestock farms on native grasslands: A case of co-innovation in Rocha, Uruguay
(Elsevier, 2021-06)CONTEXT: Family-run cow-calf farms based on native grasslands exhibit low economic and social sustainability, as reflected in low family incomes and high workloads. Experimental results have shown that pasture–herd interaction ... -
Understanding introduction history: Genetic structure and diversity of the edible ectomycorrhizal fungus, Suillus luteus, in Patagonia (Argentina)
(Taylor & Francis, 2021-06)Suillus luteus is a common ectomycorrhizal (EM) fungus associated with several Pinus species. It is distributed throughout the Northern Hemisphere and has been introduced into South America and New Zealand. We examined the ... -
A combination of rules govern fruit trait preference by frugivorous bat and bird species: nutrients, defence and size
(Elsevier, 2021-06)Several hypotheses explain how sensory, anatomical and physiological constraints drive fruit preference in frugivores. Optimal diet theory (ODT) states that frugivores make decisions based on the energy contained in food. ... -
