Polistes dominula (Hymenoptera: Vespidae) paper wasps detect native grasshoppers using olfactory cues
(Wiley, 2023-10)Polistes dominula is an invasive social wasp that preys on the grasshopper Dichroplus elongatus, which constitutes a potential agricultural pest in Northwest Patagonia. This grasshopper feeds on a wide variety of plants, ... -
Population ecology and classical biological control of forest insect pests in a changing world
(Elsevier, 2022-09-15)Forests are important for climate regulation and provide wood and fiber to an increasing human population. Forest systems encompass a large part of the world’s land surface area and they are increasingly threatened by ... -
Population genetic structure and historical dispersal patterns in the subterranean rodent Ctenomys “chasiquensis” from the southeastern Pampas region, Argentina
(Elsevier, 2016-05)Gene flow plays an essential role in the evolutionary history of the organisms and helps to identify those historical landscape features that most likely had affected the dispersal patterns. In this work, we assess, using ... -

Potential impact of the leaf‐cutting ant Acromyrmex lobicornis on conifer plantations in northern Patagonia, Argentina
(Wiley, 2011-05)The economic losses associated with crop damage by invasive pests can be minimized by recognizing their potential impact before they spread into new areas or crops. We experimentally evaluated the preferences of the ... -
Pre-Selection test to identify high responder donor goats
(2016)The aim of the study was to evaluate the feasibility of pre-selection of high or low responder does prior to the superovulatory protocols. Twenty Saanen does received 800 IU of equine chorionic gonadotropin (eCG) at the ... -
Predicting North American Scolytinae invasions in the Southern Hemisphere
(2017-01)Scolytinae species are recognized as one of the most important tree mortality agents in coniferous forests worldwide, and many are known invaders because they are easily transported in wood products. Nonnative trees planted ... -
Predicting poaching hotspots in the largest remnant of the Atlantic Forest by combining passive acoustic monitoring and occupancy models
(Elsevier, 2022-08)Poaching can have major impacts on wild animal populations and is pervasive in tropical regions. The spatial distribution of this furtive activity is particularly difficult to estimate in large natural areas, and this ... -
Predicting the distribution of plant species from southern South America: are the hotspots of genetic diversity threatened by climate change?
(Springer, 2024-01)Biodiversity in all its dimensions is being threatened by climate change and the impact of human activities. Genetic diversity is a key dimension of biodiversity underlying adaptation to global changes. Here we assess the ... -
Prediction of hydraulic conductivity loss from relative water loss: new insights into water storage of tree stems and branches
(Wiley, 2019-04)More frequently occurring, drought waves call for a deeper understanding of tree hydraulics and fast and easily applicable methods to measure drought stress. The aim of this study was to establish empirical relationships ... -
Preselection of high and low ovulatory responders in sheep multiple ovulation and embryo transfer programs
(2015)The present study evaluated the feasibility of carrying out an easy-to-handle and cost-efficient test for the preselection of high– and low–ovulatory responder ewes under superovulatory protocols. The test was based on the ... -
Pretreatments Effect in Drying Behaviour and Colour of Mature and Immature ‘Napolitana’ Sweet Cherries
(Springer, 2014-06)The effect of different treatments on drying behaviour and colour of mature and immature cherries (Napolitana var.) has been studied. Drying was carried out at 70 °C with air at 4 m/s speed and 8 % relative humidity, and ... -
