Applying sterols and bile acids as biomarkers for identifying human versus wild animals' faecal traces in cave sediments at archaeological sites

open access: yesArchaeometry, Volume 67, Issue 4, Page 1022-1039, August 2025.
Abstract Faecal biomarkers are used to trace and identify the source of faecal matter at various types of archaeological sites. Until now, the focus has been centred on humans and domesticated animals. However, in caves, it's wild animals that play a role in the deposition of organic matter.

Lords of the flies: dipteran migrants are diverse, abundant and ecologically important

open access: yesBiological Reviews, Volume 100, Issue 4, Page 1635-1659, August 2025.
ABSTRACT Insect migrants are hugely abundant, with recent studies identifying the megadiverse order Diptera as the major component of many migratory assemblages. Despite this, their migratory behaviour has been widely overlooked in favour of more ‘charismatic’ migrant insects such as butterflies, dragonflies, and moths.

A Real Option Approach to the Protection of a Habitat Dependent Endangered Species [PDF]

open access: yes
We use a real option approach to determine optimally when a social planner has to stop or resume logging in situations where an endangered species relies on forest habitat for its survival, and that habitat evolves stochastically.
