Effect of population density on the development of Mesovelia furcata (Mesoveliidae), Microvelia reticulata and Velia caprai (Veliidae) (Heteroptera: Gerromorpha)

open access: yesEuropean Journal of Entomology, 2010
Population density during nymphal development affects body size, developmental rate and wing polymorphism in semiaquatic bugs. Nymphs from crowded habitats grow faster and thus gain an advantage in the later stadia.

Intraspecific Variation in Reproductive Aspects of Female Soldier Crabs, Mictyris guinotae, Between the River Mouth and Upper Reach Habitats

open access: yesMarine Ecology, EarlyView.
ABSTRACT The soldier crab, Mictyris guinotae, is a dominant intertidal crustacean associated with sand flats in the vicinity of the Urauchi River estuary on Iriomote Island, Japan. We compared various aspects of its reproductive biology at two sites (the river mouth and upper reach) on exposed bare sand flats 300 m and 3000 m upstream from the mouth ...

Reproductive biology of the Antarctic “sea pen” Malacobelemnon daytoni (Octocorallia, Pennatulacea, Kophobelemnidae)

open access: yesPolar Research, 2013
The reproductive biology of the sea pen Malacobelemnon daytoni was studied at Potter Cove, South Shetland Islands, where it is one of the dominant species in shallow waters. Specimens collected at 15–22 m depth were examined by histological analysis.

Methods for the analysis of early oogenesis in zebrafish

open access: yesDevelopmental Biology, 2016
Oocyte differentiation is a highly dynamic and intricate developmental process whose mechanistic understanding advances female reproduction, fertility, and ovarian cancer biology. Despite the many attributes of the zebrafish model, it has yet to be fully

Optical mapping reveals a higher level of large‐scale structural variants in a family with paternally transmitted myotonic dystrophy and independent Parkinson's disease

open access: yesThe Journal of Pathology, Volume 270, Issue 1, Page 83-97, September 2026.
Abstract Myotonic dystrophy type 1 (DM1) is a clinically challenging multisystem neuromuscular hereditary disorder, with generational increase in severity and earlier age at onset. It is caused by an unstable cytosine‐thymine‐guanine repeat expansion at the DMPK locus, accompanied by associated genetic and epigenetic modifications.

Rearing conditions and life history influence the progress of gametogenesis and reproduction performances in pikeperch males and females

open access: yesAnimal, 2018
Pikeperch (Sander lucioperca) is a highly valuable fish in Europe. However, development of aquaculture of pikeperch is highly limited due to seasonality of production. This can be overcome by the controlled reproduction of domesticated fish.

Identification of New Regulators of the Oocyte-to-Embryo Transition in Drosophila

open access: yesG3: Genes, Genomes, Genetics, 2020
At the oocyte-to-embryo transition the highly differentiated oocyte arrested in meiosis becomes a totipotent embryo capable of embryogenesis. Oocyte maturation (release of the prophase I primary arrest) and egg activation (release from the secondary ...

A multiplex tissue resource for high‐resolution spatial protein profiling in the Human Protein Atlas

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Spatially resolved protein expression is essential for understanding tissue organization, cellular specialization, and protein function. The open‐access Human Protein Atlas database (www.proteinatlas.org) has generated an extensive antibody‐based tissue resource for a majority of the human protein‐coding genes using conventional ...

Comparative Study of Laboratory Diets for Piophila casei: Beneficial Effects of Infant Formula Supplementation

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 9, Page 1033-1041, September 2026.
The infant formula‐based diet (F), the whole powder milk diet (P), and dry‐cured ham (H) were evaluated for rearing Piophila casei. H accelerated development, promoted earlier reproduction, and achieved the highest demographic performance but showed practical limitations linked to substrate deterioration. F enhanced larval survival and adult longevity,
