Constraining Greenhouse Gas Cycling and Emissions in Africa's Largest Humic Lake

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Humic tropical lakes and wetlands are globally important sources of atmospheric greenhouse gases (GHGs). However, mechanistic insight into GHG cycling in such systems remains limited—especially in understudied central Africa. To address this, here we measured high‐, falling‐, and low‐water seasonal concentrations and isotopic compositions of ...

Capturing Spatial Gradients of Water Color and Clarity in Subtropical Reservoirs During Drought

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Reservoirs have spatial variation in water depth, suspended matter, and biogeochemistry that can influence patterns of water clarity and color. Spatial surveys with sensor‐equipped boats matched in time with satellite image acquisition provide data‐intensive avenues for understanding spatial patterns of optical properties within reservoirs. We

A Novel In Situ Experimental Setup for Studying the Impact of Bedform Celerity on 2D Oxygen Distribution in the Hyporheic Zone of Streams

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Hydrodynamic and morphodynamic forces interacting across the sediment‐water interface control the biogeochemistry in the hyporheic zone. When investigating the redox zonation within streambeds, dissolved oxygen (O2) is considered a key solute to the understanding of river ecosystems.

Elements of the Structure of Macrophyte Metacommunities in Coastal Wetlands: Relationships With Limnological and Climatic Variables

Ecological Research, Volume 41, Issue 2, March 2026.
We applied the Elements of Metacommunity Structure (EMS) framework to macrophyte communities across coastal wetlands in southern Brazil, identifying distinct distribution patterns among functional groups. Our results show that environmental and climatic factors shape these patterns differently, with emergent species forming Clementsian communities and ...

A global estimator of C and N isotope baselines for fresh waters

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 992-1006, March 2026.
Abstract Baselines are the pebbles in the shoes of isotope ecologists. The extreme variability of the isotope composition of resources at the base of food webs governs the spatial differences of consumers' isotope composition, so that isotope‐inferred trophic properties can be compared across ecosystems only after correction for baseline effects ...

Aquatic Biodiversity of the Pampa Biome: Insights From a Scientometric and Systematic Perspective

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT The Pampa biome, in South America, covers parts of Brazil, Uruguay, and Argentina. Its main characteristic is the predominance of grassland areas. The Pampa biome supports high biological diversity and a wide variety of ecosystems. In this study, we provide a comprehensive overview of biodiversity studies focusing on freshwater ecosystems of ...

Taxonomy and Functional Traits Modulate the Environmental Niche Dimensions of Crustacean Zooplankton Communities in Submerged Aquatic Vegetation Beds

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Community ecologists now recognise the importance of simultaneously integrating spatial and environmental processes, together with functional traits and phylogeny to provide a more complete understanding of community responses to environmental conditions.

Disentangling the Components Shaping Aquatic Richness Over Spatial Scales in Extreme Climatic Events

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Species richness in a region can be partitioned into three components: (1) spatial aggregation of individuals, (2) variation in total individual density and (3) species abundance distribution (SAD). However, it remains unclear how the influence of these components on richness changes under extreme climatic events.

Retrogressive Thaw Slumps Produce a Changing Disturbance Regime for Arctic Stream Invertebrates

Global Change Biology, Volume 32, Issue 3, March 2026.
Climate change is causing permafrost to thaw, resulting in the formation of large craters in the ground called thaw slumps, which deposit sediments and nutrients into rivers and continually impact stream ecosystems over time. We returned to slump impacted streams 10 years after an initial sample period and found that slumps permanently change streams ...

Resilience of riparian spiders to floods: evidence from a mesocosm study

Insect Conservation and Diversity, Volume 19, Issue 2, Page 393-403, March 2026.
Mesocosm experiment to assess the impact of flood duration on flood‐naïve riparian spider communities. In May, spider richness decreased with flood duration, while in June, flood duration increased abundance, richness and promoted wetland specialists. Flood‐naïve riparian spiders unexpectedly appear highly resilient to flooding.
