The SAURON project - XIII. SAURON-GALEX study of early-type galaxies: the ultraviolet colour-magnitude relations and Fundamental Planes [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
We present GALEX far (FUV) and near (NUV) ultraviolet imaging of 34 nearby early-type galaxies from the SAURON representative sample of 48 E/S0 galaxies, all of which have ground-based optical imaging from the MDM Observatory. The surface brightness profiles of nine galaxies show regions with blue UV-optical colours suggesting recent star formation ...

When and why to give shorebirds a head start

open access: yesConservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

The fundamental group and the magnitude‐path spectral sequence of a directed graph

open access: yesJournal of the London Mathematical Society
AbstractThe fundamental group of a directed graph admits a natural sequence of quotient groups called ‐fundamental groups, and the ‐fundamental groups can capture properties of a directed graph that the fundamental group cannot capture. The fundamental group of a directed graph is related to path homology through the Hurewicz theorem.

Risks of concealing environmental degradation

open access: yesConservation Biology, EarlyView.
Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...

Environmental Stress Drives Plasticity in Sexual Bimaturism in the Black Soldier Fly (Hermetia illucens Linnaeus, 1758)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 736-749, July 2026.
We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of

What's there beyond the sun and the sea? Detecting tourists' interest towards nature in a mass tourism destination using social media data

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1802-1816, June 2026.
Abstract Nature‐based tourism is a rapidly growing subsector of the international tourism industry. However, capturing broad‐scale patterns of nature visits during touristic trips or visitors' appreciation of nature may be difficult using traditional data sources and methods. In this study, we harness geotagged social media data to understand the scale
