The Elbe Estuary Microbiome Shifts With Salinity and Discharge and Depends on Fresh Organic Matter and Nutrient Availability

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.

Flooding greatly affects the diversity of arbuscular mycorrhizal fungi communities in the roots of wetland plants. [PDF]

PLoS ONE, 2011
The communities of arbuscular mycorrhizal fungi (AMF) colonizing the roots of three mangrove species were characterized along a tidal gradient in a mangrove swamp.

Analysis of Nematode Ventral Nerve Cords Suggests Multiple Instances of Evolutionary Changes to Neuron Number

Evolution &Development, Volume 28, Issue 2, June 2026.
“Analysis of Nematode Ventral Nerve Cords Suggests Multiple Instances of Evolutionary Addition and Loss of Neurons” Han et al. DAPI staining of Xiphinema sp. (Clade 2) highlighting the neuronal‐like nuclei within the ventral nerve cord. ABSTRACT Despite their diversity in habitats, nematodes are often considered to have a highly conserved neuroanatomy.

Microbial endolithic community at Meteor Crater

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 955-962, June 2026.
Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

Phloxine B Staining is Compatible With High‐Throughput DNA Barcoding of Meiofauna

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Modern, integrative biodiversity research requires methods capable of bridging the gap between detailed morphological observations and the scalability of DNA sequencing. For small, transparent, and highly abundant animals like meiofauna, sorting specimens from the matrix forms a major bottleneck, as the use of commonly used stains can inhibit ...

Developing SSU rDNA metagenomic profiles of aquatic microbial communities for environmental assessments [PDF]

Ecological Indicators, 2008
Five water samples from three sources, two municipal reservoirs in central North Carolina and Toolik Lake in Alaska, were processed to conduct a comparative survey of microbial small subunit rDNA sequences. Genomic DNA was extracted and amplified by PCR using universal SSU rDNA primers to generate 16S and 18S rDNA clone libraries and 50 clones from ...

Taxon-rich multigene phylogeny of photosynthetic euglenoids (Euglenophyceae)

Frontiers in Ecology and Evolution, 2015
To establish taxonomy and understand phylogenetic relationships among strains and species of the photosynthetic euglenoids, we performed phylogenetic analyses based on a four gene sequence dataset (nr SSU and LSU rDNA, and pt SSU and LSU rDNA) from 343 ...

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
