Synthetic pelagic biomass size spectra of the tropical and subtropical Atlantic

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Synthetic normalized biomass size spectra (NBSS) comprising non‐synoptically sampled phytoplankton, meso‐ and macrozooplankton, and micronekton including mesopelagic fishes were explored to analyze pelagic community structure in seven regions of the tropical and the subtropical Atlantic representative of different water bodies (NE Brazil shelf,

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

Acta 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 ...

Comparative Assessment of Freshwater Biodiversity in Los Morales Reservoir (Madrid) Using eDNA Collected From Sponges and Water Filtration

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Filters and freshwater sponge tissue recover a comparable number of taxa through eDNA metabarcoding. Filters detect more taxa, followed by sponge tissue when host‐blocking primers are used. Each method reveals different community compositions, so combining both approaches is recommended to achieve a more realistic representation of the metazoan ...

Unraveling Long‐Term Microsporidia Diversity and Dynamics in Lake Aydat (France) Through Paleogenomics

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Sedimentary ancient DNA study revealed 138 years of hidden microsporidian (unicellular eukaryotic parasite) diversity and host–parasite dynamics in a freshwater lake. A major community shift in the 2000s, linked to anthropogenic pressures, shows how paleogenomics reveals the diversity and long‐term ecological trajectories of these previously overlooked

Migration rate, timing of sex, and resident genetic diversity jointly shape effective gene flow during rotifer colonization

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract Dispersal is a complex process that affects all living organisms, with the settlement phase being particularly critical. This phase depends on the interaction between the environmental conditions of the new habitat and the biological traits of both resident and immigrant populations.

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

Oikos, Volume 2026, Issue 5, May 2026.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.
