Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

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

open access: yesThe 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 ...

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

open access: yesWildlife 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.

MaNGA DynPop. VII. A Unified Bulge–Disk–Halo Model for Explaining Diversity in Circular Velocity Curves of 6000 Spiral and Early-type Galaxies

open access: yesThe Astrophysical Journal Supplement Series
We derive circular velocity curves (CVCs) from stellar dynamical models for ∼6000 nearby galaxies in the final data release of the Sloan Digital Sky Survey-IV MaNGA survey with integral-field spectroscopy, exploring connections between the inner ...

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

open access: yesIntegrative 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.

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

open access: yesAnimal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.

The Growth of Galaxy Stellar Haloes over 0.2 ≤ z ≤ 1.1

open access: yesThe Astrophysical Journal
Galaxies are predicted to assemble their stellar haloes through the accretion of stellar material from interactions with their cosmic environment. Observations that trace stellar halo buildup probe the processes that drive galaxy size and stellar mass ...

Quantifying galaxy structure

open access: yes, 2018
This thesis is an effort to explore and quantify galaxy morphology and study processes involved in galaxy formation and evolution as a function of that morphology. In the main project of this work, the morphology of galaxies is analysed using machine learning techniques.
