Novas ocorrências de Lecane no plâncton de distintos ambientes da planície de inundação do alto rio Paraná = New occurrences of Lecane in plankton in different environments of the upper Paraná river floodplain

open access: yesActa Scientiarum: Biological Sciences, 2008
A planície de inundação do alto rio Paraná possui grande diversidade de rotíferos, com 288 táxons planctônicos registrados. Estudos realizados, nesse ecossistema, desde 1992, mostram que Lecanidae é a família mais especiosa, com 45 táxons registrados ...

Desiccation tolerance mechanisms in the green lineage and beyond

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3159-3175, September 2026.
Ancient origin and recurrent evolution of desiccation tolerance in the green lineage. Summary Water is essential for life on Earth, yet some plants can survive the near‐complete loss of cellular water, a trait known as desiccation tolerance. Although rare in vegetative tissues of vascular plants, desiccation tolerance is scattered across the plant ...

Response of the Diet Composition of Carassius auratus to Water Quality in Dianchi Lake, China

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Understanding the relationship between the diet composition of fish and water quality is significant for assessing fish responses to habitat changes. However, due to the complexity and diversity of both fish feeding and water quality, the relationship between the diet composition of fish and water quality is not fully understood to date.

Morphological Characterization and Complete Mitochondrial Genome of a New Epizoic Hexamerous Brittle Star Gymnolophus sexradia sp. Nov

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This study describes a new hexamerous epizoic brittle star species, Gymnolophus sexradia sp. nov., from the South China Sea, which lives on crinoid hosts and exhibits a six‐armed body plan possibly indicating fissiparity. Its vertebral and arm plate structures enhance horizontal flexibility for grasping the host, and phylogenetic analysis based on ...

Beyond the Cascade Dams: Scale‐Dependent Effects on Zooplankton Stability in River Ecosystems

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Cascade dams alter river zooplankton community stability, but how regulating factors act across local and regional spatial scales is poorly understood. Using field sampling and structural equation modeling, we revealed divergent scale‐dependent responses of zooplankton stability to dams—local stability depended on biodiversity, while regional stability

Desiccation to DNA: Bulk DNA Metabarcoding of Macroinvertebrate Egg Banks via Sugar‐Flotation Enhances Biodiversity Surveys of Dry Salt Lakes

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Ephemeral salt lakes in arid Australia contain hidden macroinvertebrate biodiversity in sediment egg banks, but traditional artificial rehydration surveys may miss taxa with specific or poorly understood hatching requirements. This study found that sugar‐flotation followed by DNA metabarcoding greatly improved detection of resting‐stage taxa compared ...

Maternal age effects on offspring lifespan and reproduction vary within a species

open access: yesEcology and Evolution
Across diverse taxa, offspring from older mothers have decreased lifespan and fitness. Little is known about the extent to which maternal age effects vary among genotypes for a given species, however, except for studies of a few arthropod species.

Salinity, turbidity, and chlorophyll drive zooplankton succession in a temperate estuary under anthropogenic pressure

open access: yesLimnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Estuarine zooplankton are vital primary consumers and essential for estuarine ecosystem functioning and productivity, but they face strong physico‐biochemical gradients and often anthropogenically altered habitats that impact their succession.

Multitrophic alpha and beta diversity of lake plankton across Canada

open access: yesOikos, Volume 2026, Issue 8, August 2026.
Anthropogenic environmental changes impact freshwater biodiversity globally. While biodiversity assessments in freshwater environments have traditionally focused on individual groups of organisms or trophic levels, considering patterns of ‘multitrophic biodiversity' across the food web provides a more comprehensive view of anthropogenic impacts and ...
