Neutral and adaptive loci reveal fine-scale population structure in Eleginops maclovinus from north Patagonia. [PDF]
Ecol Evol, 2022 Patagonia is an understudied area, especially when it comes to population genomic studies with relevance to fishery management.; Using RADseq we found that neutral and adaptive loci reveal fine‐scale population structure in Eleginops maclovinus.; We found loci putatively associated with salinity suggesting that it may act as a selective driver in E ...

Vegetation responses to past volcanic disturbances at the Araucaria araucana forest-steppe ecotone in northern Patagonia. [PDF]
Ecol Evol, 2022 Although past volcanic eruption might have affected the distribution of Araucaria' populations, thus its conservation status, I found no evidences that past tephra fall has impacted negatively the populations far from the volcanic source. Early succecional stages after severe tephra fall deposition were better explained by Ephedra' drought tolerance ...

Genomic Signals of Local Adaptation Associated With Environmental Variables in <i>Eleginops maclovinus</i> From Northern Chilean Patagonia. [PDF]
Ecol EvolStudying evolutionary processes in the unique and understudied Patagonian fjord ecosystem is a challenging task for evolutionary ecologists. Genomic signals of local adaptation are present in a species from northern Chilean Patagonia. Polygenic selection drives local adaptation in Eleginops maclovinus. ABSTRACT Understanding the evolutionary mechanisms

Journal of Contingencies and Crisis Management, Volume 31, Issue 4, Page 1018-1033, December 2023., 2023 Abstract This article focuses on communities that reoccupy territories affected by volcanic eruptions to extend understanding of people's social appropriation of environments exposed to natural hazards. We take as a case study three rural settlements affected by several eruptions from the Carran‐Los Venados and Puyehue‐Cordón Caulle volcanic systems ...

Earth and Space Science, Volume 10, Issue 10, October 2023., 2023 Abstract Up‐to‐date topography data sets are essential for forecasting volcanic hazards and monitoring deformation. Digital elevation models are used to quantify eruption rates, used in flow modeling programs, and are necessary to accurately process interferometric synthetic aperture radar data for surface deformation.

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 9, September 2023., 2023 Abstract Breadcrust bombs formed during Vulcanian eruptions are assumed to originate from the shallow plug or dome. Their rim to core texture reflects the competition between cooling and degassing timescales, which results in a dense crust with isolated vesicles contrasting with a highly vesicular vesicle network in the interior. Due to relatively fast

Lichen ecophysiology in a changing climate
American Journal of Botany, Volume 110, Issue 2, February 2023., 2023 Abstract Lichens are one of the most iconic and ubiquitous symbioses known, widely valued as indicators of environmental quality and, more recently, climate change. Our understanding of lichen responses to climate has greatly expanded in recent decades, but some biases and constraints have shaped our present knowledge. In this review we focus on lichen

Environmental risk assessment of non‐native salmonid escapes from net pens in the Chilean Patagonia
Reviews in Aquaculture, Volume 15, Issue 1, Page 198-219, January 2023., 2023 Abstract Here, we review extensive information to estimate environmental risks from escaped non‐native salmonids based on the assessments of hazard, sensitivity and exposure of discrete water bodies in Chile. In 2020, the country harvested about 1 million tons salmonids from net pens located along 1500 km of highly biodiverse coastline.

Guanaco colonisation of Tierra del Fuego Island from mainland Patagonia: Walked, swam, or by canoe?
Geo: Geography and Environment, Volume 9, Issue 2, July‐December 2022., 2022 A geographical and biological puzzle that has perplexed scientists since the late 1800s working in southern South America: why are there so few vertebrates on the island of Tierra del Fuego compared to the adjacent Patagonia mainland, including the absence of the ubiquitous Guanaco (Lama guanicoe), wild camelid of the south? An interdisciplinary search
