Mass mortality of saguaros (Carnegiea gigantea) from windthrow: A rare, demographic disturbance in a desert ecosystem

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Windthrow is a significant disturbance in many forests globally during which strong winds damage trees or other large flora, yet its role in arid ecosystems remains largely understudied. The saguaro cactus (Carnegiea gigantea), a keystone species of the Sonoran Desert, is a long‐lived, massive succulent whose demography is primarily thought to

Depositional Interplay Between the Ancestral Rocky Mountains and Ouachita–Marathon–Sonora Orogenies: Insights From Provenance Records in the Late Palaeozoic Marfa Basin, West Texas, USA

Basin Research, Volume 38, Issue 2, March–April 2026.
Provenance records from the late Palaeozoic Marfa Basin in West Texas reveal the transition from the Ancestral Rocky Mountains to the Ouachita–Marathon–Sonora orogenies during the early Permian in SW Laurentia. ABSTRACT The Marfa Basin in West Texas is a late Palaeozoic synorogenic depocenter associated with regional deformation linked to the Ancestral

Hard Rock Buffet: Chemosynthetic Carbon Use and Environmental Trophic Structuring of Carbonate‐Associated Macrofauna at Southern California Methane Seeps

Marine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT Diverse invertebrate communities inhabiting carbonate rocks at methane seeps may rely on a mix of local chemosynthetic production and sinking photosynthetic organic matter, with relative importance shaped by environmental conditions. We investigate the contribution of chemosynthetic carbon to macrofaunal diets at six Southern California ...
