Elevation shapes alpine snow algal blooms and their influence on albedo reduction
New Phytologist, Volume 251, Issue 5, Page 2482-2496, September 2026.Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak
New Phytologist, Volume 251, Issue 5, Page 2392-2406, September 2026.We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Ecology and Evolution, Volume 16, Issue 8, August 2026.We model autumn stopover distribution of UK common cuckoos across two migration routes, revealing distinct environmental drivers and key geographic hotspots. Iberian mountain systems and the Po watershed emerge as critical stopover regions, with climate, elevation, habitat heterogeneity, and hunting risk shaping route‐specific patterns.

Operational Greenhouse Gas Emissions Inventory of a University Campus in Brazil
Environmental Quality Management, Volume 36, Issue 2, August 2026.ABSTRACT Climate change mitigation requires robust greenhouse gas (GHG) accounting frameworks capable of identifying major emission sources within institutional systems. Higher education institutions represent complex operational environments characterized by substantial energy demand, transportation activities, and material consumption, all of which ...

Wildlife Monographs, Volume 223, Issue 1, August 2026.We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Key sources of uncertainty in process‐based modeling of live fuel moisture content
New Phytologist, Volume 251, Issue 4, Page 1723-1737, August 2026.Location of the selected live fuel moisture content (LFMC) sampling sites. Summary Process‐based models that mechanistically represent water‐carbon balances in the atmosphere‐soil–plant continuum are an attractive tool for monitoring live fuel moisture content (LFMC) dynamics, a key variable when assessing fire danger.
