Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

JWST NIRCam Observations of the Globular Cluster Population of RXJ 2129.7+0005

The Astrophysical Journal
We present an analysis of the globular cluster (GC) population in the galaxy cluster RXJ 2129.7+0005 ( z = 0.234) based on JWST NIRCam imaging in three filters: F115W, F150W, and F200W.

Improved Constraints on Mergers with SZ, Hydrodynamical simulations, Optical, and X-ray (ICM-SHOX) [PDF]

EPJ Web of Conferences
Galaxy cluster mergers are representative of a wide range of physics, making them an excellent probe of the properties of dark matter and the ionized plasma of the intracluster medium.

Application of three-body stability to globular clusters: I. The stability radius

, 2014
The tidal radius is commonly determined analytically by equating the tidal field of the galaxy to the gravitational potential of the cluster. Stars crossing this radius can move from orbiting the cluster centre to independently orbiting the galaxy.

Challenges in Bringing Pangenome Research Into Breeding: A Case Study in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Crop breeding has entered the pangenomics era, unlocking a far more comprehensive view of genetic diversity than a single reference genome can capture. In rice (Oryza sativa), a staple crop critical to global food security, the construction of pangenome resources has uncovered extensive structural variations (SVs), presence/absence variations (

DIFFERENT APPROACHES FOR DARK MATTER HALOS OF CLUSTERS OF GALAXIES

Odessa Astronomical Publications, 2014
To describe the density profile of dark matter halos of clusters of galaxies, we compare the approach based on the Schwarzschild-de Sitter metric with a recentlydeveloped mechanical one (discrete cosmology inside the cell of uniformity).

The evolution of the colour-magnitude relation and of the star formation activity in galaxy clusters since z~0.8

, 2008
We present recent results on the evolution of the colour-magnitude relation and of the star formation activity in galaxy clusters since z~0.8. Results are based on the ESO Distant Cluster Survey (EDisCS) - an ESO large programme aimed at the study of ...

Stellar Populations and Radial Migrations in Virgo Disk Galaxies

, 2012
We present stellar age profiles for 64 Virgo cluster disk galaxies whose analysis poses a challenge for current galaxy formation models. Our results can be summarized as follows: first, and contrary to observations of field galaxies, these cluster ...
