Scheffrahnitermes ubuntu (Isoptera: Apicotermitinae), Description of a New Termite Using a Collaborative Approach to Address the Wallacean Shortfall

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
The study of Neotropical Apicotermitinae remains challenging due to the large number of undescribed taxa (Linnean shortfall) as well as the scarcity of distributional data (Wallacean shortfall). Despite recent efforts to reduce the first one, the second remains an even more significant challenge.

Galaxy quenching in various environments

open access: yes, 2023
Already early studies of the morphology-density relation of galaxies showed that early-type galaxies lie in the centres of rich clusters, and in small groups in filaments between clusters, where they are located closer to filament axis than late-type galaxies. This means that galaxies are indeed pre-processed in groups. In our present study we searched

Constraining the Quenching Mechanisms in Galaxies

open access: yes, 2022
A number of theoretical mechanisms have been invoked to explain the transformation of star forming galaxies into quenched galaxies, such as the removal of gas by active galactic nuclei- (AGN) and star formation-driven galactic outflows, and the heating of the galaxy halo and subsequent halting of gas accretion caused by virial shocks and preventative ...

Unravelling Taxonomic Complexity in Elusive Cetaceans: Mitogenome Insights into Evolutionary History and Cryptic Diversity of Bryde's Whales

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The Bryde's whale is one of the least understood baleen whale species globally, limiting accuracy of regional and global conservation assessment. This study shows the occurrence of unique genetic lineages and evolutionary histories among Bryde's whale populations.

The Effect of Environment on the Properties of the Most Massive Galaxies at 0.5 < z < 2.5 in the COSMOS-DASH Field

open access: yesThe Astrophysical Journal, 2023
How the environment influences the most massive galaxies is still unclear. To explore the effects of the environment on morphology and star formation in the most massive galaxies at high redshift, we select galaxies with stellar mass $\mathrm{log}({M}_ ...

Archives of impact: The politics of craters on Earth

open access: yesGeographical Research, Volume 64, Issue 2, May 2026.
This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

SDSS-IV MaNGA: The Roles of AGNs and Dynamical Processes in Star Formation Quenching in Nearby Disk Galaxies

open access: yes, 2019
We study how star formation (SF) is quenched in low-redshift disk galaxies with integral-field spectroscopy. We select 131 face-on spiral galaxies with stellar mass greater than $\rm 3\times10^{10}M_\odot$, and with spatially resolved spectrum from MaNGA

Hunting strategies, success, and sustainability: A case study in a community forest on the edge of Salonga National Park, DRC

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
In Central Africa, traditional hunting is central to the way of life of local communities. However, increasing demand for wild meat has raised concerns about the sustainability of this practice. With a year‐long analysis of hunting strategies and their impact at the outskirts of Salonga National Park, Democratic Republic of the Congo, we showed a ...

Galaxy Quenching at the High Redshift Frontier: A Fundamental Test of Cosmological Models in the Early Universe with JWST-CEERS

open access: yesThe Astrophysical Journal
We present an analysis of the quenching of star formation in massive galaxies ( M _* > 10 ^9.5 M _⊙ ) within the first 0.5–3 Gyr of the Universe’s history utilizing JWST-CEERS data.

Taking Care of Business in a Flash: Constraining the Timescale for Low-Mass Satellite Quenching with ELVIS

open access: yes, 2015
The vast majority of dwarf satellites orbiting the Milky Way and M31 are quenched, while comparable galaxies in the field are gas-rich and star-forming.
