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 ...

Two-mediator dark matter models and cosmic electron excess
Journal of High Energy Physics, 2019 The cosmic electron energy spectrum recently observed by the DAMPE experiment exhibits two interesting features, including a break around 0.9 TeV and a sharp resonance near 1.4 TeV.

Rotation of Galaxies and Dark Matter
SSRN Electronic Journal, 2022 In a previous paper by the author was proposed a new metric for the gravitational field of a thin rotating disk physically different from the Kerr metric. The metric is admissible for any angular momentum of the disk. As demonstrated in the present paper the parameter determining the angular momentum of the Milky Way greatly exceeds its gravitational ...

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 ...

3.55 keV X-ray line signal from excited dark matter in radiative neutrino model
Physics Letters B, 2014 We study an exciting dark matter scenario in a radiative neutrino model to explain the X-ray line signal at 3.55 keV recently reported by XMN-Newton X-ray observatory using data of various galaxy clusters and Andromeda galaxy.

Noble gases and nitrogen in material from asteroid Bennu
Meteoritics &Planetary Science, EarlyView.Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Fungal ecology in the age of 'omics
New Phytologist, EarlyView.Summary The advancement of technology in recent decades has given us an unprecedented ability to observe the natural world. With modern sequencing and bioinformatics technologies, we can obtain more information about the microscopic world, and its interactions with the macroscopic world, than ever before.

DARK MATTER AND DARK ENERGY IN THE COMA CLUSTER OF GALAXIES
Odessa Astronomical Publications, 2013 The Coma cluster of galaxies is studied as a giant aggregation of dark matter and baryons embedded in the dark energy background. Key theory relations for the local dark-energy effects are given. On the basis of the theory and current observational data,
