Abstract High‐altitude hypoxia elicits several profound physiological responses, including substantial increases in muscle sympathetic nerve activity (MSNA); however, the association of this heightened MSNA with cardiovascular and cerebrovascular haemodynamics remains unclear in lowlanders and indigenous highlander populations.

ABSTRACT Here, we review the generic classification of Eucanthini, resulting in the redefinition of Eucanthus Westwood, 1848 and erection of two new genera. Under this new framework, Eucanthus is restricted to six North American species, while two monotypic genera are described from the Southern Hemisphere: Antoniocanthus gen. nov.

Dental Microwear Evidence of Holocene Dietary Variability in the Argentinian Pampas and Paraná Delta
ABSTRACT Objectives This study explores the subsistence strategies of Middle‐to‐Late Holocene human populations in the Argentinean Pampas and Paraná River Delta by analyzing dental microwear patterns. Materials and Methods We examined occlusal molar microwear textures of individuals from the Middle and Late Holocene recovered from 12 archaeological ...

Abstract Humans have influenced ecosystems for millennia, and social changes can have notable ecological effects. Recent human influence on ecosystems is exemplified by the collapse of fire regimes circa 1900 in the western United States due to increased grazing, fire suppression, and declining Indigenous fire use.

Abstract The Coastal Cordillera of northern Chile, in the forearc of the Andean subduction zone, provides an ideal site to evaluate exhumation above the oldest active subduction under extreme aridity. This range lies parallel to a sediment‐starved trench, has experienced hyperaridity since the Miocene, and is transected by the ∼1,000‐km‐long Atacama ...

Abstract Lidar observations above McMurdo, Antarctica from 2011 to 2024 are used to characterize gravity wave (GWs) potential energies (Ep ${E}_{p}$) in the mesosphere and lower thermosphere (MLT). Alongside characterizations in the middle atmosphere (30–70 km), the GW baselines show dissipation at all altitudes from 30 to 110 km.
