The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
