Fisheries Management and Ecology, Volume 33, Issue 3, Page 452-462, June 2026.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 ...

Under Pressure: Decoding the Effect of High Densities on Derived Nebular Properties
The Astrophysical JournalRecent JWST observations have uncovered a population of compact, high-redshift ( z > 6) galaxies exhibiting extreme nebular conditions and enhanced nitrogen abundances that challenge standard chemical evolution paradigms.

Journal of Computational Chemistry, Volume 47, Issue 14, 30 May 2026.PES‐trotter is a cross‐platform open‐source application for the exploration and analysis of 3D potential‐energy landscapes associated to molecular systems. Along with video‐game‐like exploration, it allows plotting energy profiles from custom paths, computing critical points and minimum‐energy paths, and playing back dynamical trajectories. PES‐trotter

Abundance determination of multiple star-forming regions in the Hɪɪ galaxy SDSS J165712.75+321141.4 [PDF]
, 2011 We analyse high signal-to-noise ratio spectrophotometric observations acquired simultaneously with TWIN, a double-arm spectrograph, from 3400 to 10 400Å of three star-forming regions in the Hɪɪ galaxy SDSS J165712.75+321141.4.

XMM Observations of Metal Abundances in Galaxy Clusters
Acta Polytechnica, 2011 The hot gas that fills the space between galaxies in clusters is rich in metals. Due to their large potential well, galaxy clusters accumulate metals over the whole history of the cluster, and retain important information on cluster formation and ...

Iron Snails: Nonequilibrium Dynamics and Spiral Abundance Patterns
The Astrophysical JournalGalaxies are not in a dynamical steady state: they continually undergo perturbations, e.g., from infalling dwarf galaxies and dark matter substructure. After a dynamical perturbation, stars phase mix toward a new steady state; in so doing, they generally

AGN outflows and the cluster cooling flow conundrum
, 2011 Temperature distributions within cores of galaxy clusters indicate gas in the core should cool down rapidly and contract. The cooling flow problem involves the hypothesis that the rapidly cooling gas should eventually condensate into unobserved molecular

Chemical Abundance Gradients in Open Clusters from the Gaia/LAMOST Sample
The Astronomical JournalBased on a large and homogeneous sample of 299 open clusters (OCs) from Gaia DR3 and large sky area multiobject fiber spectroscopic telescope DR11, we studied the abundance gradients of the α -elements Mg and Si, and the iron-peak elements Fe and Ni to ...
