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.

Scalable Benthic Biomonitoring: Trade‐Offs Between Bulk and Environmental DNA Metabarcoding Across Sediment Types

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Direct eDNA metabarcoding is the most scalable method for large benthic monitoring programs, provided that sampling effort is increased to compensate for slightly lower per‐sample biodiversity recovery. ABSTRACT DNA metabarcoding offers prospects to assess benthic biodiversity in a more scalable and comprehensive way, but processing methods remain ...

Investigating Low‐Temperature Stress Responses in Crustacea Aquatic Species Through Comparative Transcriptomics

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Crustaceans, such as shrimp and crabs, are pivotal to global aquaculture, yet their productivity is severely impacted by low‐temperature stress. This study employs comparative transcriptomic and genomic analyses to elucidate the molecular mechanisms underlying crustacean responses to cold stress across five economically significant species ...

Final Note of Special Issue “Tardigrades Taxonomy, Biology and Ecology”

Diversity, 2020
Tardigrada (water bears) are microscopic invertebrates inhabiting aquatic (freshwater and marine) and terrestrial habitats. They are thriving in almost all Earth ecosystems from deepest oceans to highest mountains, from tropics to polar regions.

Comparative Amplicon and Shotgun Metagenome Profiling of Soil Microbial Communities in Kauri Forests Affected by Phytophthora agathidicida

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Soils beneath symptomatic and asymptomatic kauri trees were analysed using LAMP, amplicon sequencing, shotgun metagenomics, and PICRUSt2. LAMP detected Phytophthora agathidicida in 39/60 samples, while shotgun metagenomics detected it at low abundance across all samples.

Geographic Variation in the Diet of Red Knot (Calidris canutus) Chicks Reflects Local Prey Communities

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim To describe and compare the diets of an Arctic‐breeding shorebird, the Red Knot (Calidris canutus), across three geographically distinct breeding sites. We aimed to document the dietary patterns and identify key prey groups that characterise each population's foraging ecology.
