Endophytic bacteria enhance macrophyte resilience but reduce microbial network stability under eutrophication

Ecological Indicators
Lake eutrophication poses a serious threat to the biodiversity and ecosystem functions of submerged macrophytes. As symbiotic microorganisms of submerged macrophyte, endophytic bacteria can enhance plant’s stress resistance and promote its growth ...

Recurrent Body Shape Patterns in Cave‐ and Surface‐Dwelling Trichomycterid Catfishes

Journal of Morphology, Volume 287, Issue 9, September 2026.
Multivariate shape analyses reveal that body shape consistently differs between cave‐ and surface‐dwelling trichomycterids in northeastern Colombia, with cave species exhibiting fusiform bodies while surface species showed deeper shapes consistently in different clades.

Role of methanotrophy in a high‐methane emitting thermokarst lake

Limnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Thermokarst (thaw) lakes are projected to be an increasing source of atmospheric methane (CH4), a potent greenhouse gas, as climate warms and permafrost thaws. However, the magnitude of CH4 cycling, particularly the role of aerobic CH4 oxidation (methanotrophy), among thermokarst lakes, is not well constrained.

Zooplankton reliance on autochthonous and allochthonous resources across mountain lakes revealed through essential amino acid δ13C analysis

Limnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Terrestrial subsidies shape aquatic ecosystem structure and function, serving as important energy channels for consumers when phytoplankton and other autochthonous resources are limited. Despite this, quantifying the assimilation of allochthonous nutrients by aquatic consumers can be challenging. Here, we show terrestrial plants, benthic algae,

Rapid phosphorus removal promotes a sustained decrease in nitrogen in eutrophic lakes

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Excess phosphorus (P) leads to lake eutrophication, prompting interventions to reduce P availability. However, we have a limited understanding of how P availability impacts nitrogen (N), which also affects lake water quality. The in‐lake application of alum rapidly decreases P availability, presenting an opportunity to explore how P influences

Effects of water regime on the growth of the submerged macrophyte Ceratophyllum demersum at different densities

Journal of Freshwater Ecology, 2018
To successfully restore deteriorated lake ecosystems, it is vital to identify influencing environmental factors that impact submerged macrophytes. Planting density and water regime are important factors for submerged macrophytes’ growth.

A MODIS-Based Novel Method to Distinguish Surface Cyanobacterial Scums and Aquatic Macrophytes in Lake Taihu

Remote Sensing, 2017
Satellite remote sensing can be an effective alternative for mapping cyanobacterial scums and aquatic macrophyte distribution over large areas compared with traditional ship’s site-specific samplings.

Higher methanotroph abundance and bottom‐water methane in ponds with floating photovoltaic arrays

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Floating photovoltaic (FPV) arrays alter the methane (CH4) cycling dynamics of waterbodies on which they are deployed. Here, we investigated dissolved CH4 dynamics and associated CH4 cycling microbial communities (methanogens and methanotrophs) in the 2nd year of FPV deployment (70% aerial coverage) in experimental ponds.

The fate of methane in ponds: Drivers of production, storage, oxidation, and emissions

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Ponds are disproportionately large contributors to global carbon cycling, with substantial but variable emissions of methane (CH4) to the atmosphere relative to their global surface area. Efforts to upscale pond CH4 emissions have focused on broad‐scale correlates of emissions, yet mechanisms underlying the variability in emissions remain ...

Seasonal Patterns and Environmental Drivers of Seagrass (Zostera muelleri) Flowering in Aotearoa New Zealand: Implications for Seed‐Based Restoration

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
Seagrass flowering underpins seed‐based restoration and is governed by the interaction of multiple abiotic and biotic drivers operating across a range of temporal and spatial scales. In New Zealand/Aotearoa, flowering was historically considered rare, but emerging evidence indicates it is more widespread than previously recognised, creating new ...
