The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
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

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

open access: yesBiological Reviews, EarlyView.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...
