Variations in the hierarchical architecture of nothofagus obliqua: evidence from juvenile naturallyregenerated trees and from seedlings obtained by controlled crosses of selected individuals
(Scion, 2025-05-10)Background: Many tree species with potential for wood production present high intra-specific variations in the extent of trunk differentiation (i.e. hierarchical architecture). The identification of multiple-scale traits ... -
Designing multifunctional forest systems in Northern Patagonia, Argentina
(Frontiers Media, 2024-08)Multifunctional productive systems based on native species management, a new paradigm that counters colonial worldviews, offer sustainable sources of food and materials while preserving biodiversity. Despite extensive ... -
Experimental assessment of warming effects on the architecture and growth of the subalpine species Nothofagus pumilio
(Oxford University Press, 2024-11)Global warming can pose a significant threat to forest tree species, particularly those inhabiting subalpine forests in temperate regions. Plasticity and adaptation are essential for the persistence of these forests. ... -
The incidence of cultural practices for managing Drosophila suzukii in raspberry farms: a case study from northwestern Patagonia
(Taylor and Francis, 2025-03)The spotted wing drosophila (SWD), Drosophila suzukii, is a global pest of soft-skinned fruit. Managing SWD is mainly difficult due to its rapid life cycle, polyphagy and insecticide resistance, which also harms beneficial ... -
Mating before host colonization: a common trait in outbreeding Scolytinae, potentially linked to invasiveness
(Schweizerbart Science Publishing, 2025-04)Little is known about the influence of mating strategies that could potentially facilitate the colonization of new hosts in outbreeding species of the weevil subfamily Scolytinae. Individuals typically emerge from their ... -
Understanding key population drivers of the spotted wing Drosophila in cultivated and natural areas in the Andes
(Springer Nature, 2025-03)The spotted-wing drosophila (SWD), Drosophila suzukii (Matsumara) (Diptera: Drosophilidae), is a serious global pest. Understanding the drivers for its success is fundamental to develop sustainable management tools. Here ... -
Warming alters the responses to light availability in seedlings from contrasting provenances of the mid-tolerant beech Nothofagus pumilio
(Elsevier, 2025-02)The survival and growth of shade-tolerant tree seedlings depend strongly on their ability to respond to varying light conditions in both natural and managed systems. Rising temperatures may constrain these light-driven ... -
Restricted Dispersal in the Late Successional Forest Tree Species Nothofagus Pumilio: Consequences Under Global Change
(Wiley, 2025-05)Plants rely on gamete dispersal to ensure the inheritance of their genes. Gene flow, mediated by pollen and seed dispersal, also fosters species' cohesion across space, facilitates population migration, and influences local ... -
Spatiotemporal variability of horsefly abundance and richness in northwestern Patagonia = Variabilidad espaciotemporal de abundancia y riqueza de tábanos en el noroeste de la Patagonia
(Sociedad Entomológica Argentina, 2025-04)Horseflies (Diptera: Tabanidae) are a nuisance to humans and livestock in many regions around the world including Patagonia, Argentina. Although in this region there are no records of Tabanidae species as vectors of ... -
On the spatio-temporal coherence of extreme precipitation indices in subtropical Argentina
(Elsevier, 2025-07)This study evaluates the spatio-temporal coherence of regional extreme precipitation indices in subtropical Argentina (STAr) derived from rain gauge station data from 1991 to 2021. For the regionalization two machine ... -
Forage selection overlap between co-occurring introduced ungulates: insights for conservation management of a Sub-Antarctic Island
(Springer, 2025-04)The presence of exotic herbivores can have detrimental effects on insular ecosystems because it usually involves the introduction of a previously absent functional group. Understanding feeding behavior is crucial to manage ... -
The role of healthy wetlands in mitigating volcanic tephra impacts in Northern Patagonia
(Elsevier, 2025-06)In natural grasslands under extensive grazing, volcanic events pose risks to livestock health and production. Volcanic tephra tends to persist and remain remobilized for years in arid and semi-arid environments, which can ... -
Los sesgos del contra-consenso eco-alarmista
(Asociación Argentina de Ecología, 2025-04)Respaldado por un artículo previo en la sección Debate, Grau (2023) propone cinco grupos de tópicos que desafían posturas presumiblemente establecidas en la comunidad de ecólogos y ambientalistas. Sobre la base de un ... -
Sex bias in parasitism by Deladenus siricidicola and its implications for the success of biological control of invasive Sirex noctilio populations
(Taylor and Francis, 2025-01)In systems with an arthropod host and a parasite, there is no general pattern in the sex bias in the infection. One of the best-studied forest pest systems involves the woodwasp pest Sirex noctilio (Hymenoptera: Siricidae) ... -
Assessment of two seed technologies for the direct seeding of Festuca pallescens, a key species for grassland restoration in Patagonia
(Wiley, 2025-03)Direct seeding of native species is a practice with high potential for the restoration of degraded areas. Since the availability of seeds of native species is often limited, it is necessary to make the most of this resource. ... -
Wild vs. cultivated strawberries: differential fruit quality traits and antioxidant properties in Fragaria chiloensis and Fragaria × ananassa
(Springer, 2025-03)Nature can contribute to human well-being in various ways, yet some culturally significant wild species remain understudied. This is the case with the red form of Fragaria chiloensis subsp. chiloensis, a wild relative of ... -
Using near-infrared spectroscopy as a cost-effective method to characterise soil and leaf properties in native forest
(Elsevier, 2025-03)Forests conservation and sustainable management of forests require an understanding of ecological traits that influence carbon and nutrient turnover in forest ecosystems. This study evaluates the potential of Near Infrared ... -
Novel associations among insect herbivores and trees: Patterns of occurrence and damage on pines and eucalypts
