International Journal of Urban and Regional Research, EarlyView.Abstract In terms of mainstream sustainability economics, market‐led initiatives aimed at biodiversity restoration represent a productive, morally conscientious choice. Under this view, efforts in areas such as biodiversity offsetting, net gain, or finance are considered effective tools for preventing or managing environmental degradation.

Star formation quenching in galaxies [PDF]
SCIENTIA SINICA Physica, Mechanica & Astronomica, 2017 The cosmic star formation rate density is peaked at $z\sim2$ and declines continuously since then, implying that the quenching of star formation has been the dominating process in galaxy evolution in the past $\sim10$ Gyr. As a result, the present day universe does not contain many star-bursting galaxies, which were the dominating population at $z\sim2$

Quenching of the star formation activity in cluster galaxies [PDF]
Astronomy & Astrophysics, 2016 We study the star formation quenching mechanism in cluster galaxies by fitting the SED of the Herschel Reference Survey, a complete volume-limited K-band-selected sample of nearby galaxies including objects in different density regions, from the core of the Virgo cluster to the general field. The SED are fitted using the CIGALE SED modelling code.

The Colors and Sizes of Recently Quenched Galaxies: A Result of Compact Starburst before Quenching [PDF]
The Astrophysical Journal, 2020 Abstract We analyze the colors and sizes of 32 quiescent (UVJ-selected) galaxies with strong Balmer absorption (EW(Hδ) ≥ 4 Å) at z ∼ 0.8 drawn from DR2 of the LEGA-C survey to test the hypothesis that these galaxies experienced compact, central starbursts before quenching.

Animal 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.

Revealing impacts of stellar mass and environment on galaxy quenching
, 2022 Aims. Galaxy quenching is a critical step in galaxy evolution. In this work, we present a statistical study of galaxy quenching in 17 cluster candidates at 0.5 < z < 1.0 in the COSMOS field. Methods.

On Our Cosmic (In)significance
Ratio, EarlyView.ABSTRACT This article discusses three interpretations of cosmic significance, all of which reveal something important about the notion of significance. Along the way, it proposes a unified view of significance by combining elements of each of the views.

A STELLAR MASS THRESHOLD FOR QUENCHING OF FIELD GALAXIES [PDF]
The Astrophysical Journal, 2012 We demonstrate that dwarf galaxies (10^7 < M_stellar < 10^9 Msun) with no active star formation are extremely rare (<0.06%) in the field. Our sample is based on the NASA-Sloan Atlas which is a re-analysis of the Sloan Digital Sky Survey Data Release 8.

Identifying and Distinguishing Quenching Galaxies with Spatially Resolved Star Formation in TNG50
The Astrophysical JournalUsing the TNG50 simulation, we determine observationally motivated metrics that can distinguish quenching galaxies from star-forming galaxies for M _* ≥ 10 ^9.5 M _⊙ , based on the spatial distribution of their stellar populations. Quenching galaxies are
