Blue plaque review series: Thomas Graham Brown: Before his time

open access: yesExperimental Physiology, EarlyView.
Abstract Thomas Graham Brown made a seminal discovery, published in 1911 while he was a Carnegie Fellow in the University of Liverpool laboratory of Nobel Prize winner Charles S. Sherrington. Working in cats, he showed that rhythmic ‘voluntary’ behaviour, such as stepping and, by inference, walking, does not result from a chain of reflex events, but ...

The “Gastric Mill” of the Crayfish [PDF]

open access: yesNature, 1880
FOR demonstrating the structure and action of the elaborate gizzard of the crayfish, which I have found to be usually regarded as a hopeless puzzle, I have constructed, in Prof. Lankester's laboratory at University College, at his suggestion and for the use of his class of practical zoology, a little model, the simplicity of which enables any student ...

The spread of non‐native species

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

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

Nonconsumptive predator effects modify crayfish‐induced bioturbation as mediated by limb loss: Field and mesocosm experiments

open access: yesEcology and Evolution, 2020
We addressed the implications of limb loss and regeneration for multispecies interactions and their impacts on ecosystem engineering in freshwater stream environments. We included regenerative and nonregenerative crayfish as well as fish predators in a 2
