Rearing duration influences survival rate in the Post‐Larval Capture, Culture and Release of a coral reef fish

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Juvenile coral reef fish face an initial predation‐induced mortality bottleneck with mortality exceeding 60% within 48 hours of settlement. This intense predation, exacerbated by anthropogenic stressors, limits recruitment and contributes to global declines of reef fish populations. Post‐Larval Capture, Culture, and Release (PCCR),

Abundance Patterns in the Interstellar Medium of the S0 Galaxy NGC 1316 (Fornax A) Revealed with Suzaku

, 2010
The Suzaku X-ray satellite observed the nearby S0 galaxy NGC 1316, a merger remnant aged 3 Gyr. The total good exposure time was 48.7 ksec. The spectra were well represented by a two-temperature thermal model for the interstellar medium (ISM) plus a ...

Metals in Star-forming Galaxies with KCWI. I. Methodology and First Results on the Abundances of Iron, Magnesium, and Oxygen

The Astrophysical Journal
Understanding the chemical enrichment of different elements is crucial to gaining a complete picture of galaxy chemical evolution. In this study, we present a new sample of 46 low-redshift, low-mass star-forming galaxies at M _* ∼ 10 ^8−10 M _⊙ along ...

The Vertical Metallicity Gradient of the Galactic Disk for Mono-age Stellar Populations in LAMOST

The Astrophysical Journal
The vertical metallicity gradient of the Galactic disk offers valuable insights into the disk’s formation and chemical evolution over time. We utilized the Large Sky Area Multi-Object Fibre Spectroscopic Telescope low-resolution spectral young stellar ...

Under Pressure: Decoding the Effect of High Densities on Derived Nebular Properties

The Astrophysical Journal
Recent 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.

Chemical Abundance Gradients in Open Clusters from the Gaia/LAMOST Sample

The Astronomical Journal
Based 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 ...

The Apache Point Observatory Extra-galactic Evolution Experiment (APOeGEE): Chemical Abundance Trends for Seven Dwarf Spheroidal Galaxies in the APOGEE Survey

The Astrophysical Journal
In addition to comprehensive surveys of the Milky Way (MW) bulge, disk, and halo, the Apache Point Galactic Evolution Experiment (APOGEE) project observed seven dwarf spheroidal satellites (dSphs) of the MW: Carina, Sextans, Sculptor, Draco, Ursa Minor ...

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 ...

A Perspective on the Milky Way Bulge Bar as Seen from the Neutron-capture Elements Cerium and Neodymium with APOGEE

The Astrophysical Journal
This study probes the chemical abundances of the neutron-capture elements cerium and neodymium in the inner Milky Way from an analysis of a sample of ∼2000 stars in the Galactic bulge bar spatially contained within ∣ X _Gal ∣ < 5 kpc, ∣ Y _Gal ∣ < 3.5 ...
