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 ... -
Evidence of genetic determination in the growth habit of Nothofagus pumilio (Poepp. & Endl.) Krasser at the extremes of an elevation gradient
(Taylor & Francis, 2020)In temperate mountainous regions, altitudinal clines in tree size and growth habit develop from a gradual adjustment of multiple traits to tolerate harshening conditions with altitude. We perform a common garden trial with ... -
Evidence on the response of Patagonian forage grasses to the mulching effect of recent tephra deposits in Argentina
(Taylor & Francis, 2017-08-31)In Patagonia, arid and semiarid lands are being affected both by inappropriate management practices, which are leading to degradation, and by volcanic activity, whose effects are still unclear. This study aimed to test ... -
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 ... -
Exploring farmer perceptions of agricultural innovations for maize-legume intensification in the mid-hills region of Nepal
(Taylor & Francis, 2018)Maize-legume intercropping is a fundamental component of mixed farming systems in the mid-hills of Nepal. However, its productivity is constrained by several biophysical and social factors, and limited adoption of proven ... -
Exploring nutrient-sensitive landscape configurations for rural communities in southern Mexico
(Elsevier, 2024-06)In Mexico, the traditional MILPA polycropping system is giving way to maize monocultures, impacting the nutritional diversity of smallholder farmers and diminishing ecosystem services. This study explores landscape ... -
Exploring solution spaces for nutrition-sensitive agriculture in Kenya and Vietnam
(Elsevier, 2020-04)Smallholder agriculture is an important source of livelihoods in South Asia and sub-Saharan Africa. In these regions the highest concentrations of nutritionally vulnerable populations are found. Agricultural development ... -
Extensive pollen flow in a natural fragmented population of Patagonian cypress Austrocedrus chilensis
(Springer, 2014-12)Habitat fragmentation might significantly affect mating and pollen dispersal patterns in plant populations, contributing to the decline of remnant populations. However, wind-pollinated species are able to disperse pollen ... -
Factors affecting success of galls of Aditrochus coihuensis (Hymenoptera: Pteromalidae) = Factores que afectan el éxito de las agallas de Aditrochus coihuensis (Hymenoptera: Pteromalidae)
(Sociedad Entomológica Argentina, 2011-12)Galls of Aditrochus coihuensis (Hymenoptera: Pteromalidae) were collected from their host tree, the southern beech Nothofagus dombeyi, near San Carlos de Bariloche, Argentina, during the spring of 2007. Galls were carefully ... -
Factors driving historic intercontinental invasions of European pine bark beetles
(Springer, 2022-06)Largely assisted by global trade, alien insect species are being introduced into new territories at unprecedented rates. Among forest insects, pine bark beetles (Coleoptera: Curculionidae, Scolytinae) are a large and diverse ... -
Factors influencing the effectiveness of group interactions among international and interdisciplinary early‑career researchers working toward environmental sustainability in climate change
(Springer, 2022-11)Global warming is a current problem that needs to be addressed by collaborating with researchers from different disciplines and expertise. There is a concern about training the next generation of scientists to holistically ... -
