Subtle differences in spring soil moisture can substantially influence annual productivity in a semiarid grassland

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract In the C4‐dominated semiarid grasslands of the western Great Plains (Colorado, USA), spring soil moisture (soil volumetric water content, SoilVWC) is thought to be a critical determinant of aboveground net primary production (ANPP) and overall carbon cycling. However, because evidence for this is based on observational studies, we attempted to

Nutrient enrichment strengthens feedbacks that promote and stabilize coral‐to‐macroalgae regime shifts on tropical reefs

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Ecosystems around the world have experienced shifts in community state as a result of anthropogenic activities that alter important ecological feedbacks. On coral reefs, transitions to a state where fleshy macroalgae are a major space holder have often been associated with the loss of top‐down control, which frequently has been attributed to ...

Landsystems of the tropical high Peruvian Andes: Glaciers, lakes, wetlands and water resources in the Cordillera Vilcanota

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
We outline the geomorphological relationships between glaciers, lakes and bofedal wetlands, and the way in which moraines, talus slopes and sandar interact with catchment hydrology in the tropical Andes of Peru. Bofedales are well developed within glacial limits, with glacial processes such as erosion and formation of moraines providing the poorly ...

Geomorphic Effectiveness of an Extreme Flood in a Mountain River: Evidence From Pre‐ and Post‐Event Surveys in a Subtropical Region of Southern Brazil

Hydrological Processes, Volume 40, Issue 5, May 2026.
The extreme flooding of April 2024 caused a complete “geomorphic reset”, resulting in a 24% widening of the channel and a transition to critical or supercritical flow regimes. The energy of the event broke through the stable armouring layer, reducing the armouring ratio from 7.9 to 4.9 and intensely removing fine sediments from the subsurface.
