PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

open access: yesEcography, Volume 2026, Issue 8, August 2026.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.

Lessons from a decade of lake management: effects of herbicides on Eurasian watermilfoil and native plant communities

open access: yesEcosphere, 2017
Eurasian watermilfoil (Myriophyllum spicatum) is a non‐native and invasive aquatic macrophyte with a broad North American distribution. It can have significant negative effects on invaded waterbodies, including decreased native macrophyte diversity ...

Aquatic macrophytes of Angola: a preliminary verified checklist

open access: yesPhytoKeys
Aquatic macrophytes are photosynthetic macroscopic organisms that grow permanently or periodically submerged or floating on the surface of the water. The aim of this study is to compile a checklist of fresh-water aquatic vascular plant macrophytes occurring in Angola, focusing on their origins, life forms, conservation status and distribution ...

Spatial variability of hydrodynamics in oyster reefs: Investigating the impact of canopy density on mean and turbulent flows

open access: yesLimnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract This field study investigated how oyster canopy density modulates hydrodynamics of natural intertidal oyster reef. High‐resolution velocity measurements were taken simultaneously within and above oyster canopies of variable density (solid volume fractions, Ø=$$ \mathrm{\O}= $$ 0.04–0.21).

Quantifying temporal dynamics of greenhouse gas emissions in lake mesocosms: Deployment of a low‐cost measurement system

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 8, August 2026.
Abstract Greenhouse gas (GHG) emissions from freshwater ecosystems contribute significantly to global carbon budgets, yet they remain poorly constrained due to limited high‐frequency measurements. We tested a low‐cost, high‐frequency GHG measurement system in a long‐term mesocosm experiment in Lemming, Denmark, over a 7‐month period, focusing on CO2 ...

Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

open access: yesOikos, Volume 2026, Issue 8, August 2026.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...

The Influence of Macrophytes on Aquatic Microclimate

open access: yes, 2023
How terrestrial vegetation influences microclimate and what effects this has on associated ecosystems is well studied, but it is less known if and how aquatic macrophytes affect their microclimate. In this study I therefore aim to investigate the question of how aquatic macrophytes influence their microclimate, and how these effects in turn may affect ...

The loss of an Indigenous‐maintained She‐Oak woodland in southeast Australia

open access: yesGeographical Research, Volume 64, Issue 3, August 2026.
A 2600‐year multi‐proxy palaeoecological record (pollen, charcoal, and sediment) from Balfour Swamp, east Gippsland, reveals the persistence of an open, grassy She‐Oak woodland maintained by GunaiKurnai. This vegetation community, resilient to climatic variability and fire, was lost following the disruption of Aboriginal land management and replaced by

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

open access: yesFisheries Management and Ecology, Volume 33, Issue 4, Page 784-798, August 2026.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.
