Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).

Los humedales pampeanos como herramientas para preservar las lagunas

open access: yesBiología Acuática, 2019
Wetlands are ecosystems with known potential for particulate material retention. Many water bodies develop near shore wetlands or reed belts supported by external natural o artificial incomes from the drainage basin.

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

SCIENTIFIC PRODUCTION SUPPORTED BY LIMNOLOGICAL RESEARCH IN PORTUGUESE-SPEAKING COUNTRIES AND LEGISLATION RELATED TO SUSTAINABLE DEVELOPMENT GOAL 6 (SDG 6) IN CPLP MEMBER STATES

open access: yesEnvironmental Smoke
This study aimed to analyze limnological scientific production from 1996 to 2022 within the community of Portuguese-speaking countries. Additionally, the study investigates the decline in scientific production in 2022, potentially associated with the ...

The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.

Could Lake Joyce have acted as a long-lived proglacial refugium in Antarctica’s McMurdo Dry Valleys?

open access: yesArctic, Antarctic, and Alpine Research
Lake Joyce of the McMurdo Dry Valleys (MDV), Antarctica, contains an endemic copepod population (Diacyclops joycei) that has not been identified from apparently suitable habitats in nearby lakes.

Comparing species accumulation within taxonomically well‐ and poorly resolved insect groups over 37 years

open access: yesInsect Conservation and Diversity, EarlyView.
Here, we used a unique 37‐year (1969–2006) freshwater macroinvertebrate time‐series, collected over seven sites in central Germany, to study biodiversity patterns and species accumulation over time. Accumulation curves of Diptera diversity have not reached a plateau in 37 years of sampling.

Trophic niche overlap between native and non‐native fishes in central Anatolian lakes, Türkiye

open access: yesJournal of Fish Biology, EarlyView.
Abstract The Central Anatolian region of Türkiye exhibits exceptionally high freshwater fish diversity and endemism and is increasingly exposed to the introduction of non‐native taxa. We examined the diet composition, prey selectivity and interspecific dietary overlap among eight native and five non‐native fish species across seven lakes in Central ...

Linking variation in genome size to cyst size in chrysophytes

open access: yesJournal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.

Saffron aqueous extract effects on paraquat and glyphosate concentration in common carp (Cyprinus carpio) tissues

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Reduced bioaccumulation of PQ and GLY by saffron extract in Common carp (Cyprinus carpio) tissues Abstract Herbicides such as paraquat (PQ) and glyphosate (GLY) pose ecological and public health risks because of their persistence, bioaccumulation, and toxicity to aquatic organisms. This study evaluated whether aqueous saffron extract (Crocus sativus L.)
