Terrestrial Isopods as Biotic Generators of Microplastics Following Chronic Exposure to Weathered Low‐Density Polyethylene

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial detritivores such as isopods and springtails play a vital role in cycling nutrients through soil ecosystems. Microplastics (MPs, < 5 mm) are increasingly recognized as contaminants of terrestrial soils, yet little is known about whether soil invertebrates themselves are impacted by consuming these plastics or if they can generate ...

Describing novel mitochondrial genomes of Antarctic amphipods

Mitochondrial DNA. Part B. Resources, 2022
To date, only one mitogenome from an Antarctic amphipod has been published. Here, novel complete mitochondrial genomes (mitogenomes) of two morphospecies are assembled, namely, Charcotia amundseni and Eusirus giganteus.

Biodiversity effects on ecosystem functioning are driven by resource quality and contamination

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Biodiversity–ecosystem functioning relationships are increasingly explained by species' traits and resource quality differences rather than richness alone, yet cross‐trophic effects and environmental context remain poorly resolved.

Newly described amphipod species already under threat [PDF]

, 2016
Biologists at Eawag have described a new amphipod species which is endemic to the Alps. While alpine lakes provide relatively undisturbed habitats for Gammarus alpinus, this species is being displaced by an invasive amphipod in Lake ...

Extremely low biodiversity Arctic intertidal habitats as sentinels for environmental change

Frontiers in Marine Science
The Arctic is undergoing dramatic changes, including an unprecedented decline in sea ice. Previous studies have shown the severe structuring impact of sea ice scour upon polar intertidal communities.

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

Integrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Development of Single-Nucleotide Polymorphism Markers and Population Genetic Analysis of the Hadal Amphipod Alicella gigantea across the Mariana and New Britain Trenches

Journal of Marine Science and Engineering
Alicella gigantea, the largest amphipod scavengers found to date, play key roles in the food web of the hadal ecosystem. However, the genetic structure of A. gigantea populations among different trenches has not been reported yet.

Cosmopolitan landhopper Talitroides topitotum (Crustacea, Amphipoda, Talitridae) in Java, Indonesia [PDF]

Check List, 2016
The native land and freshwater amphipod fauna of Indonesia is little known. Meanwhile, the readily human-dispersed talitrid amphipod Talitroides topitotum (Burt, 1934), reported to have displaced native landhoppers in certain parts of the world, is found

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

Integrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

Osteological, Biological, and Genetic Consequences of Colonization of Fresh Waters by Marine Cottoid Fishes (Cottidae)

Integrative Zoology, EarlyView.
Lacustrine forms of Triglopsis from North American and European lakes are at different stages of evolution, making them a suitable model for testing hypotheses about evolutionary patterns and rates. An integrative analysis of morphological, genetic, and biological adaptations occurring in lacustrine forms of the genus Triglopsis was carried out.
