Genomic responses to climate: Understanding local adaptation in the Andean tree species Nothofagus pumilio and implications for a changing world
(Wiley, 2024-03)Nothofagus pumilio is a foundation tree species that inhabits a 2000-km-long range in the southern Andes, a region with two perpendicular environmental gradients: temperature and photoperiod (North–South), and precipitation ... -
Enhanced high-spatial resolution radiographic images based on COTS CMOS image sensors applied to wood dendrochronology and densitometry
(Elsevier, 2024-03)The imaging of wood samples using X-rays for the study of dendrochronology and densitometry is predominantly conducted through analog films subsequently digitized or, in more advanced instances, with expensive flat-panel ... -
Evaluation of the toxicological effects of Neltuma alpataco (Prosopis alpataco) pod alkaloid extract
(Elsevier, 2024-04)The pods of Neltuma spp. have shown potential as a source of protein and energy in livestock. However, prolonged consumption of some of these species can lead to neurological symptoms in ruminants. This study aimed to ... -
Mitochondrial DNA lineages and genetic variation of early growth traits in the Argentinean breeding population of Pinus ponderosa Douglas ex C. Lawson
(Springer, 2024-03)In the Andean-Patagonian region of Argentina, Pinus ponderosa Douglas ex C. Lawson is the most widely cultivated forest tree species. Its breeding program, started in 1998, is now progressing towards the establishment of ... -
Tracking floristic archetypes of Patagonian steppes
(Wiley, 2024-03)Questions: The classification of plant communities is a well-established practice in ecology. However, the factors that determine the distribution of common species and the extent of their dominance and overlap are still ... -
Coping or adapting strategies? The importance of distinguishing between climatic shift and drought events for proper management of the pastoral systems in Northern Patagonia
(Springer, 2024-02)Drier conditions have been observed in Northern Patagonia, Argentina, in the last decades, affecting the pastoralism production system. In this context, two laws were promoted to foster goat and sheep production. This ... -
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 ... -
Micro-Environmental Variation in Soil Microbial Biodiversity in Forest Frontier Ecosystems—Implications for Sustainability Assessments
(MDPI, 2024-02)Soil health indicators based on microbial biodiversity are increasingly used in agricultural sustainability assessments. However, little is known about how microbial communities vary within micro-environmental gradients ... -
Economic costs of invasive non-native species in urban areas: an underexplored financial drain
(Elsevier, 2024-03)Urbanization is an important driver of global change associated with a set of environmental modifications that affect the introduction and distribution of invasive non-native species (species with populations transported ... -
Distribution, Invasion History, and Ecology of Non-native Pine Bark Beetles (Coleoptera: Curculionidae: Scolytinae) in Southern South America
(Springer, 2024-01)The growth of international trade, coupled with an expansion of large-scale pine plantations in South America during the second half of the twentieth century, has significantly increased the opportunities for the invasion ... -
A Key Interaction Behind the Scenes: Dung Beetles in Livestock Production from Arid and Semi-Arid Rangelands
(Springer, 2024-02)Pastoralism is a dominant agricultural activity in arid and semi-arid ecosystems. The interaction between coprophagous insects and livestock is a key but an undervalued topic in rangeland management decisions. The objective ... -
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 ... -
Effects of elevated CO2 on the water hyacinth-biocontrol agent Megamelus scutellaris (Hemiptera: Delphacidae) and its yeast-like symbiotes
(Elsevier, 2024-01)Water hyacinth, Pontederia crassipes, is a highly invasive plant native to South America and one of the most invasive aquatic plants in the world. For its control, the planthopper Megamelus scutellaris Berg (Hemiptera: ... -
Comportamiento hidrológico de un paisaje con diferentes estados del pastizal en la Patagonia árida
(Asociación Argentina de la Ciencia del Suelo, 2023-12)En Patagonia árida, la forma de uso de la tierra más extendida es el pastoreo por ganado doméstico. A pesar de ello, la región carece de un entendimiento acabado sobre la generación de los flujos de escorrentía en áreas ... -
Sugar responsiveness could determine foraging patterns in yellowjackets
(Nature, 2023-11)Sympatric-related species often exhibit resource partitioning. This can occur through diferent mechanisms, such as behavioral, morphological, and sensory variations, leading to qualitative, temporal, or spatial diferences ... -
Análisis de la susceptibilidad a la erosión hídrica en una cuenca de la Patagonia árida bajo distintos escenarios = Analysis of water erosion susceptibility at an arid Patagonia watershed in different scenarios
(Instituto Interuniversitario de Geografía, Universidad de Alicante, 2023-12)La erosión hídrica es una de las principales causas de degradación de tierras. Las estimaciones de erosión son fundamentales para la optimización de estrategias de conservación de suelos. Por eso estudiamos la susceptibilidad ... -
Integrating family farmers’ perceptions with meteorological records and national climate change projections to enhance site-specific adaptation knowledge
(Springer, 2023-12)Adaptation strategies to climate change (CC) that do not consider local perspectives tend to fail at specifc sites. Searching for complementary actions, we aimed to assess how farmers’ perceptions about climatic hazards ... -
