The Benefit of Maternal Care and Infanticide by Males as Reproductive Strategies in a Caprellid Amphipod. [PDF]
Ecol EvolIn the marine amphipod Caprella kominatoensis, males perform infanticide to terminate maternal care and accelerate female molting for mating opportunities. However, we found that maternal defense is effective when the female parent is larger than the intruding male.

Gammarus (Amphipoda) species competitive exclusion or coexistence as a result of climate change in the Arctic? [PDF]
Polish Polar Research, 2021 The coexistence of two congeneric amphipods, boreal Gammarus oceanicus, and arctic G. setosus, was studied during the summer seasons of 2017-2019 in the region of Isfjorden, Forlandsundet, and Prins Karl Forland island in the west-central part of the ...

Tracing growth patterns in cod (Gadus morhua L.) using bioenergetic modelling. [PDF]
Ecol Evol, 2023 A bioenergetic model, which includes in‐situ knowledge of distribution and food intake, allows tracing (seasonal) growth patterns of cod. The model shows that summer heat periods can lead to negative energy turnover, ultimately resulting in reduced growth and potentially in a reduced reproductive potential.

The urosome of the Pan- and Peracarida [PDF]
Contributions to Zoology, 2006 We have examined the caudal regions of diverse peracarid and pancarid malacostracans using light and scanning electronic microscopy. The traditional view of malacostracan posterior anatomy is not sustainable, viz., that the free telson, when present, bears the anus near the base.

Gaps and Data Ambiguities in DNA Reference Libraries: A Limiting Factor for Molecular-Based Biodiversity Assessments Using Annelids as a Case Study. [PDF]
Ecol EvolRegional DNA reference libraries are crucial for molecular biodiversity assessments, yet they remain incomplete, limiting their effectiveness. Using annelids from the Arabian Peninsula as a case study, we identified considerable gaps in species coverage and minimal representation in public databases.

Food intake of early juvenile western Baltic cod (Gadus morhua) during settlement transition. [PDF]
J Fish BiolAbstract This study examines the gut contents of 203 early juvenile Atlantic cod [17–101 mm ± 18.48 mm standard deviation (SD)] from the Western Baltic Sea (ICES Subdivision 22) collected between 2020 and 2022. According to the observed prey (proportion of pelagic, intermediate and benthic items) in the cod guts, settlement transition from a pelagic to
