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. ... -

(Springer, 2020-02)Several European and Mediterranean species of pine bark beetles (Coleoptera: Curculionidae: Scolytinae) have become established in North America and the southern hemisphere, posing a novel threat to planted and naturally-occurring ... -
A Framework to tackling the synchrony between Social and Ecological phases of the annual cyclic movement of transhumant pastoralism
(MDPI, 2020-04)Transhumant pastoralism is mobile livelihood strategy in which families and their herds move seasonally from lowlands, where they settle during the winter, towards the highlands, located in mountainous areas, during the ... -
A multivariate geostatistical framework for combining multiple indices of abundance for disease vectors and reservoirs: a case study of rattiness in a low-income urban Brazilian community
(The Royal Society Publishing, 2020-09-02)A key requirement in studies of endemic vector-borne or zoonotic disease is an estimate of the spatial variation in vector or reservoir host abundance. For many vector species, multiple indices of abundance are available, ... -
A successful vitrification technique for goat morulae conservation
(Elsevier, 2022-04-01)The aim of this study was to evaluate the effect of different vitrification and warming processes on the in vitro embryo survival of caprine morulae, considering the day of recovery. A total of 136 morulae of Criolla-Neuquina ... -
A synthesis on the impact of non-native conifer plantations on ant and beetle diversity in norh-western Patagonia
(2018-03)Softwood forestry with non-native tree species is increasing worldwide and especially in many developing countries of the Southern Hemisphere. Tree plantations are beneficial in environmental and socioeconomic aspects, but ... -
Adaptability to climate change in forestry species : drought effects on growth and wood anatomy of ponderosa pines growing at different competition levels
(2012)More stressful conditions are expected due to climatic change in several regions, including Patagonia, South-America. In this region, there are no studies about the impact of severe drought events on growth and wood ... -
Addition of eCG to a 14 d prostaglandin treatment regimen in sheep FTAI programs
(Elsevier, 2020-10)In the present study, there was evaluation of the alternative of adding eCG as part of a longinterval prostaglandin-F2α (PG) treatment on the reproductive efficiency of Merino sheep during the breeding season. A total of ... -
Aeolian Remobilisation of the 2011-Cordón Caulle Tephra-Fallout Deposit: Example of an Important Process in the Life Cycle of Volcanic Ash
(Frontiers Media SA, 2020-01-14)Although volcanic eruptions represent short periods in the whole history of a volcano, the large amount of loose pyroclastic material produced, combined with aeolian processes, can lead to continuous, long-lasting reworking ... -
Aeolian Remobilisation of Volcanic Ash: Outcomes of a Workshop in the Argentinian Patagonia
(Frontiers Media, 2020-11-27)During explosive volcanic eruptions, large quantities of tephra can be dispersed and deposited over wide areas. Following deposition, subsequent aeolian remobilisation of ash can potentially exacerbate primary impacts on ... -
Aerobic Metabolism Alterations as an Evidence of Underlying Deltamethrin Resistance Mechanisms in Triatoma infestans (Hemiptera: Reduviidae)
(Entomological Society of America, 2020-06)Triatoma infestans (Klug, 1834), the main vector of Chagas disease in Latin America, is regularly controlled by spraying the pyrethroid deltamethrin, to which some populations have developed resistance. The three main ... -
Afforestations and wetlands, are they a good combination? Study of water fluxes in two cases of Patagonian wetlands
(Wiley, 2015-04)Wetlands are ecosystems that play a key role in maintaining biodiversity and associated economies (e.g. agriculture and livestock) because they are reservoirs of water and carbon. Globally, these environments have been ... -
Aggressive tree killer or natural thinning agent? Assessing the impacts of a globally important forest insect
