Lessons Learnt From Long‐Term Monitoring of River Restoration in an English Chalk Stream

open access: yesRiver Research and Applications, Volume 42, Issue 6, Page 1209-1222, July 2026.
ABSTRACT River restoration can be difficult to evaluate due to insufficient monitoring over timescales too short to adequately capture physical and ecological response. To better understand restoration outcomes, this study quantified changes in physical habitat (depth, velocity, substrate composition) and macroinvertebrates at two restoration projects ...

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

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

open access: yesEvolution &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.

Native and Non‐Native Populations Respond Unevenly to River Barrier Removals

open access: yesGlobal Change Biology, Volume 32, Issue 6, June 2026.
While barrier removals restore river connectivity and promote recovery of native populations, they may also facilitate non‐native species, creating a ‘connectivity conundrum’. Using a systematic review and meta‐analysis, we show that both native and non‐native populations can benefit from barrier removal, with outcomes being context‐dependent ...

Chordodes colchis (Nematomorpha, Gordiida), a new species from Georgia

open access: yesZoosystematics and Evolution, 2017
A new species, Chordodes colchis, is described from several locations in Georgia. The species resembles some other Chorodes species, especially C. anthophorus, which has also been described from Georgia, but differs in conspicuous details.

Aquatic Macroinvertebrates of Arid and Semi-Arid Ecosystems of Peru

open access: yesFrontiers in Environmental Science, 2021
Peru is one of the megadiverse countries worldwide, displaying a great diversity of ecosystems due to its tropical location, marine currents, and complex relief, which jointly define environments differentiated by altitude and climatic conditions.

Trophic Niche Overlap Between the Invasive Crab Rhithropanopeus harrisii (Gould, 1841) and Native Crab Species in the Southwest Atlantic Coast

open access: yesMarine Ecology, Volume 47, Issue 3, May/June 2026.
ABSTRACT The introduction of exotic species is one of the main drivers of biodiversity loss in aquatic ecosystems. The Harris mud crab Rhithropanopeus harrisii, native to the Atlantic coast of North America, was recorded in the Patos Lagoon estuary (southern Brazil) in the 1980s, likely introduced via ballast water. However, the effects of this invader
