Blount J, Rowland H, Mitchell C, Speed M, Ruxton G, Endler J, et al.
Proc Biol Sci
. 2023 Jan;
290(1991):20222068.
PMID: 36651049
In a variety of aposematic species, the conspicuousness of an individual's warning signal and the quantity of its chemical defence are positively correlated. This apparent honest signalling is predicted by...

BMC Ecol Evol
. 2021 Feb;
21(1):25.
PMID: 33583398
Background: Animals use diverse antipredator mechanisms, including visual signalling of aversive chemical defence (aposematism). However, the initial evolution of aposematism poses the problem that the first aposematic individuals are conspicuous...

Wang L, Ruxton G, Cornell S, Speed M, Broom M
J Theor Biol
. 2019 Apr;
473:9-19.
PMID: 31004613
We introduce a general theoretical description of a combination of defences acting sequentially at different stages in the predatory sequence in order to make predictions about how animal prey should...

Wang L, Cornell S, Speed M
J Theor Biol
. 2018 Oct;
462:194-209.
PMID: 30300647
The defences used by organisms against predators display a great degree of variability. Defence phenotypes can differ substantially among individuals of the same species, and a single individual can itself...

Cuthill I, Allen W, Arbuckle K, Caspers B, Chaplin G, Hauber M, et al.
Science
. 2017 Aug;
357(6350).
PMID: 28774901
Coloration mediates the relationship between an organism and its environment in important ways, including social signaling, antipredator defenses, parasitic exploitation, thermoregulation, and protection from ultraviolet light, microbes, and abrasion. Methodological...

Jones R, Fenton A, Speed M
Behav Ecol
. 2016 Mar;
27(2):645-651.
PMID: 27004015
Aposematism is a well-known strategy in which prey defend themselves from predation by pairing defenses such as toxins, with warning signals that are often visually conspicuous color patterns. Here, we...

Speed M, Arbuckle K
Biol Rev Camb Philos Soc
. 2016 Mar;
92(2):815-829.
PMID: 26932796
While much of evolutionary biology attempts to explain the processes of diversification, there is an important place for the study of phenotypic similarity across life forms. When similar phenotypes evolve...

Higginson A, Speed M, Ruxton G
Am Nat
. 2015 Dec;
186(6):728-41.
PMID: 26655980
Inconspicuous prey pay a cost of reduced feeding opportunities. Flowers are highly nutritious but are positioned where prey would be apparent to predators and often contain toxins to reduce consumption....

Arbuckle K, Speed M
Proc Natl Acad Sci U S A
. 2015 Oct;
112(44):13597-602.
PMID: 26483488
The "escape-and-radiate" hypothesis predicts that antipredator defenses facilitate adaptive radiations by enabling escape from constraints of predation, diversified habitat use, and subsequently speciation. Animals have evolved diverse strategies to reduce...

New Phytol
. 2015 Aug;
208(4):1251-63.
PMID: 26243527
Many plant species produce defensive compounds that are often highly diverse within and between populations. The genetic and cellular mechanisms by which metabolite diversity is produced are increasingly understood, but...
