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.

Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

Acta Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...

Enhanced fecundity and parasite release in the first amphipod invader on the Iberian Peninsula

Knowledge and Management of Aquatic Ecosystems, 2018
Crangonyx pseudogracilis is a North American amphipod recently detected in Portugal and it is the first invasive freshwater amphipod detected in the Iberian Peninsula. The aim of this study was to assess the population structure and its invasion range in

Functional characterization of 42 CK2α de novo variants associated with Okur‐Chung neurodevelopmental syndrome

The FEBS Journal, EarlyView.
Okur‐Chung neurodevelopmental syndrome (OCNDS) is a neurodevelopmental disorder associated with mutations in the gene coding for Protein kinase CK2α. In this work, 42 variants of CK2α associated with OCNDS were characterized in vitro. This included determination of catalytic activity and CK2α/CK2β‐interaction as well as an assessment of evolutionary ...

The influence of a cooling water system on waterbird habitat use in a coastal environment

Ibis, EarlyView.
This study investigated the impact of a cooling water system at a nuclear power plant in northern Europe on coastal waterbird habitat use. In winter, the cooling water system provided preferential areas for waterbirds with warm productive waters, and, more importantly, with ice‐free areas.

The complete mitochondrial genome of the deep-sea amphipod Eurythenes magellanicus (Crustacea: Amphipoda: Lysianassidae)

Mitochondrial DNA. Part B. Resources, 2020
The complete mitochondrial genome of the deep sea amphipod Eurythenes magellanicus was determined in this paper. This molecular was 14,988 bp in length, and contained the typical 13 protein coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal ...

Polar cod Boreogadus saida occurrence is driven by temperature at the margin of its distribution

Journal of Fish Biology, EarlyView.
Abstract With a warming Arctic, suitable habitat for polar cod Boreogadus saida (Lepechin 1774) is predicted to decrease. We investigated the changes in distribution of polar cod on the southern limit of its distribution in the Atlantic Ocean (around Iceland) during both autumn and spring after a recent period of warming in the area.

Diet of juvenile skipjack herring Alosa chrysochloris: Ontogenetic shifts, predator–prey size ratios and mouth gape allometry

Journal of Fish Biology, EarlyView.
Abstract The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi ...

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.

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
