Fiddler crabs can feel more than we think: the influence of neighbors on the activities of the fiddler crab Leptuca uruguayensis
Fiddler crabs have been used as model organisms in many laboratory and field studies. In their natural environment, social interaction with other fiddler crabs (conspecific or heterospecific) is recurrent, but...

Influence of climate, physical and chemical variables on the taxonomic and functional responses of macroinvertebrate communities in tropical island rivers
Rivers of tropical islands formed by volcanic eruptions experience unpredictable and heavy rainfall and are characterised by irregular topography. During the 2019 and 2020 low-water season, we investigated the...

Open AccessLagrangian dynamics of the spring zooplankton community in a large river
Zooplankton may represent a considerable part of plankton in large rivers, but little is known about the factors that control it. We hypothesized that (1) significant longitudinal increase of zooplankton abund...

Differences in fluctuating asymmetry and liver mass in a population of amphibians affected by the rupture of the Fundão dam, the largest environmental disaster in Brazil
The Fundão dam collapse in 2015 resulted in the largest environmental disaster in Brazil’s history with the release of tons of ore tailings mainly in aquatic environments. Amphibians are susceptible to contami...

Establishment success of alien Daphnia in the ancient Lake Biwa: insights from sedimentary archives
Invasive species pose serious threats to global biodiversity, prompting studies to identify factors underlying invasion and establishment success. However, it's difficult to discern these factors due to the ab...

Open AccessDownstream passage performance of silver eel at an angled rack: effects of behavior and morphology
The European eel is critically endangered due to heavy impact of anthropogenic factors, such as habitat fragmentation, overexploitation and climate change. During downstream migration, silver eels may encounte...

Open AccessDynamic adaptation of phytoplankton vertical migration to changing grazing and nutrient conditions
Despite the ubiquitous occurrence of vertical migration of phytoplankton its quantitative significance remains poorly known. We eliminated a dense Daphnia population in a pond by introducing whitefish fingerlings...

Conservation implications of somatic growth and length-at-age in Pseudemys gorzugi, Rio Grande Cooter
Conservation decisions are often based on population models that rely on underlying assumptions made about species' demographic parameters. The Rio Grande Cooter (Pseudemys gorzugi) is a conservation-dependent ri...

Change in growth and prey utilization for a native salmonid following invasion by an omnivorous minnow in an oligotrophic reservoir
Aquatic invasive species can affect food web structure, native fish growth, and production, depending on the traits of the invasive species and the pre-invasion conditions of the ecosystem. Thermal tolerances ...

Isotopes suggest trophic differences between alien Radix auricularia (Linnaeus, 1758) (Lymnaeidae) and sympatric endemic gastropods in Lake Baikal
In recent decades, the Eurasian native and invasive gastropod Radix auricularia has been found widely dispersed in the endemic communities of Lake Baikal. A comparative analysis of stable carbon (δ13C) and nitrog...

Open AccessDual effects of drying and urban pollution on leaf litter decomposition and shredder consumption in permanent and intermittent streams
In the present study we investigated the combined effect of flow intermittence and wastewater treatment plant (WWTP) effluent on leaf litter decomposition in two Mediterranean streams with permanent and interm...

Article
How a mega-dam in the Amazon’s largest tributary altered the drivers of planktonic communities
Community drivers shift over time in response to changes in landscape and environmental conditions. Although dams alter the landscape (e.g., by flooding areas) and environment (e.g., by increasing transparency...

Evolutionary trends in encephalic morphology among Geophagini cichlid fish: phylogenetic insights and associations with ecological and behavioral traits
The gross encephalic morphology of representatives from 17 genera within the Geophagini tribe is comprehensively characterized, compared, and analyzed into a previously proposed phylogenetic hypothesis. Our mo...

The impact of climatic conditions and food availability on bimodality size structure and density of YOY pikeperch (Sander lucioperca)
Understanding inter-annual variation in the density of young-of-the-year fish is an important tool for assessing stock status and guiding management decisions. We analyzed data spanning from 2003 to 2022 colle...

Drivers of macroinvertebrate assemblages in littoral and pelagic habitats of a large shallow lake: implications for bioassessment
Different measures of macroinvertebrate diversity (species diversity, functional diversity, phylogenetic diversity) and functional feeding groups (FFGs) are commonly used to assess the ecological status of lar...

Taxonomic and functional Odonata assemblage metrics: macrophyte–driven changes in anthropogenically disturbed floodplain habitats
Floodplains are heterogeneous systems adjacent to large rivers periodically flooded by water originating from the river’s lateral flow. During floods, the water flows into the surrounding channels, ponds and l...

Open AccessResistance not resilience traits structure macroinvertebrate communities in newly drying stream sections
Transitioning from perennial to non-perennial flow regimes causes ecological shifts in aquatic communities. Aquatic macroinvertebrates deploy resistance and resilience strategies to cope with flow intermittenc...

The Role of Histone H2B Acetylation Modification in Aluminum-Induced Cognitive Dysfunction
Aluminum (Al) is a low toxic trace element that can accumulate in the nervous system and induce cognitive disorders characterized by reduced learning and memory ability. Neuroepigenetic effects are structural ...
