The morphosedimentary record of glacial to postglacial environmental changes in West Wiyâshâkimî impact crater lake and adjacent areas, northern Québec, Canada

open access: yesBoreas, EarlyView.
Crater lakes in core regions of former ice sheets have the potential to preserve long‐term sedimentary archives that are otherwise rare in glaciated landscapes due to pervasive glacial erosion. Lake Wiyâshâkimî, an impact crater lake located in the inner core of the Québec‐Labrador Dome of the Laurentide Ice Sheet, provides a rare example of such a ...

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

open access: yesConservation Biology, EarlyView.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Parsimonious machine learning for the global mapping of aboveground biomass potential

open access: yesEcography, EarlyView.
Advances in computational power and methods, and the widespread availability of remote sensing data have driven the development of machine learning models for estimating global carbon storage. Current models often rely on dozens of predictor variables to estimate aboveground biomass density (AGBD), resulting in accurate but complex models that are ...

Basaltic Explosive Volcanism in a tuff-dominated Intraplate Setting, Sarmiento Formation (Middle Eocene- lower Miocene), Patagonia Argentina

open access: yesLatin American Journal of Sedimentology and Basin Analysis
The Sarmiento Formation (middle Eocene to early Miocene) represents the distal record of the activity of the Andean volcanic arc in central Patagonia, mainly dominated by accumulation and reworking of fine ash in a low-gradient continental setting ...

Charles Darwin y las glaciaciones más antiguas de Patagonia: los bloques erráticos del alto valle del Río Santa Cruz [PDF]

open access: yes, 2009
Although the depositational environment assigned by Darwin to the large erratic blocks and gravels in the Río Santa Cruz valley has been reinterpreted, his geomorphological and stratigraphic observations are still in force.

Circular economy business strategies and public schemes: a game theory‐based survey

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract This paper develops a selected survey based on game theory in circular economy (CE) by complementing two perspectives: the CE business strategies and the public schemes (PS) available to implement CE systems. These perspectives are concentrated in six CE business strategies (circular inputs, sharing platforms, product‐as‐a‐service (PaaS ...

Disentangling the Evolutionary History of the Woody Species in Earth's Most Diverse Tropical Savanna

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim We investigate the evolutionary structure of vegetation assemblages in the Cerrado Domain, the main extent of savanna in the American Tropics, a biodiversity hotspot, to understand the role of ecological and geographical factors in constraining plant diversification and shaping biogeographic patterns across this complex mosaic of ...
