Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

People and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

Exploring the Gas-phase Metallicity Gradients of Star-forming Galaxies at Cosmic Noon

The Astrophysical Journal
We explore the relationships between the [O/H] gas-phase metallicity radial gradients and multiple galaxy properties for 238 star-forming galaxies at 0.6 < z < 2.6 selected from the CANDELS Ly α Emission at Reionization survey with stellar mass $8.5\lt ...

Co-evolution of the Milky Way high- and low-α sequences with chemical evolution models

Astronomy & Astrophysics
Context. Observational data have revealed a clear dichotomy in the [α/Fe] versus [Fe/H] diagram of the Milky Way thick and thin disc stars. Many recent studies have shown evidence of a co-evolution phase between the high- and low-α disc sequences as well

Saving Bambi from the mower? Using a drone with thermal camera to evaluate a low‐tech scaring technique to reduce roe deer fawn mortality during grass harvest

Wildlife Biology, EarlyView.
Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

Subsystems of the Galactic halo, their structures and compositions

Odessa Astronomical Publications, 2017
It is shown that general populations of globular clusters and metal-poor field stars are components at least of three subsystems occupying different volumes in the Galaxy.

Effect of Salinity Stress on Gut–Brain–Gonad Axis in the Red‐Eared Slider (Trachemys scripta elegans)

Integrative Zoology, EarlyView.
The increase in salinity leads to changes in the gut microbiota and metabolites of Trachemys scripta elegans, affecting the synthesis and secretion of neurotransmitters or precursors, which can inhibit the secretion of reproductive hormones and affect the self‐renewal and differentiation process of spermatogonial stem cells.

Abundance jump in the inner bulges of galaxies [PDF]

Symposium - International Astronomical Union, 1993
The metallicity difference of about an order between the kinematically decoupled nuclei and the surrounding bulges is found in 3 spiral galaxies possessing an axisymmetric potential in their centres.

TYC 170–1218–1: A new r-process-enhanced extremely metal-poor star, rich in Th.★

Astronomy & Astrophysics
Context. Extremely metal-poor (EMP) stars are formed from gas clouds enriched by one or a few supernova explosions belonging to the first stellar generation and this very limited number of sources of metal enrichment is suitable to produce peculiar ...

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

Integrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.
