Risk Status of Australia's Alpine and Subalpine Ecosystems

open access: yesAustral Ecology, Volume 51, Issue 5, May 2026.
ABSTRACT Alpine and subalpine ecosystems are threatened by changing climate and disturbance regimes because they exist under extreme geographical and climatic conditions. Understanding the threats to and risk status of alpine and subalpine ecosystems is vital to guide their conservation, inform monitoring programs and identify the relative impact of ...

Anatomical Description of the Main Gyri and Sulci of the Telencephalon of Alouatta belzebul

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 3, May 2026.
ABSTRACT The Alouatta belzebul is a species of howler monkey, of the Atelidae family and genus Alouatta. It is endemic in Brazil and has a separate geographic distribution, with two populations occurring: in the Amazon and in the Atlantic Forest on the coast of Northeast Brazil. The species is classified as ‘vulnerable’, and this is mainly justified by

Hidden Complexity in Reservoir Flow Regulation Revealed by Spectral Analysis

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Understanding reservoir regulation of streamflow is critical for hydrological modeling and ecohydrological assessments, yet our knowledge of how reservoirs preferentially modify flow variability remains limited. Here we apply spectral analysis to daily inflow‐outflow data from 205 US reservoirs, decomposing regulation effects into operational ...

The Impact of Long-Term Generation Contracts on Valuation of Electricity Generating Assets under the Regional Greenhouse Gas Initiative [PDF]

open access: yes
The Regional Greenhouse Gas Initiative is an effort by nine states to constrain carbon dioxide emissions from the electric power sector using a cap-and-trade program. This paper assesses the importance of long-term electricity contracts under the program.

Dissolved Black Carbon in North Cascades Snow, Meltwater and a Downstream River

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Quantification of black carbon on snow in the Cascade Range is needed due to increasing wildfire intensity and frequency. Here, the benzenepolycarboxylic acid (BPCA) molecular method was used to measure dissolved black carbon (DBC) in snow, nearby rivers, streams, and supraglacial melt collected in 2022 and 2023 from Mount Baker and Mount ...
