Global Ecology and Biogeography, Volume 35, Issue 9, September 2026.ABSTRACT Aim Differences in the functional traits of co‐occurring species drive species' interactions and sustain key ecosystem services. However, the historical and contemporary environmental drivers of, as well as the surrogacy of conventional range‐based diversity metrics for, this functional diversity remain poorly understood.

Aposematism: An Alternative Hypothesis on How We Discover Medicinal Organisms [PDF]
, 2017 The most widely accepted theories as to how primates select medicinal organisms are based on smelling and tasting bitter—and most of the times toxic—plants (Etkin and Ross 1982; Johns 1990).

European Journal of Entomology, 2010 True bugs are generally considered to be well protected against bird predation. Sympatric species that have similar warning coloration are supposed to form a functional Müllerian mimetic complex avoided by visually oriented avian predators.

Unripe red fruits may be aposematic [PDF]
Plant Signaling & Behavior, 2009 The unripe fruits of certain species are red. Some of these species disperse their seeds by wind (Nerium oleander, Anabasis articulata), others by adhering to animals with their spines (Emex spinosa) or prickles (Hedysarum spinosissimum). Certainly neither type uses red coloration as advertisement to attract the seed dispersing agents.

Insect Science, Volume 33, Issue 4, Page 1706-1718, August 2026.Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (

Resolving the paradox of local warning signal diversity: A framework for hypothesis testing
Functional Ecology, Volume 40, Issue 7, Page 1950-1959, July 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Defended prey often evolve conspicuous colorations that advertise their unprofitability to predators. These visual advertisements act as honest warning signals that predators can use to avoid these prey through associative learning.

Ontogenetic colour change and the evolution of aposematism: A case study in panic moth caterpillars
, 2007 Aposematism is a widely used antipredator strategy in which an organism possesses both warning coloration and unprofitable characters. Theoretical evidence suggests that aposematic colour should develop when high opportunity costs imposed by crypsis ...

Aposematism, Crypsis and Population Differentiation in the Strawberry Poison Frog
, 2012 Evolutionary transitions between the two major predator avoidance strategies aposematism and crypsis are expected to be associated with changes in many important traits of animals.

Frontiers in Ecology and Evolution, 2018 Conspicuous coloration coupled with secondary defensive mechanisms is known as aposematic coloration and is used in predator avoidance and defense. Classic theory argues that aposematic signals tend to be more effective in larger organisms as they are ...

Shifty Frogs: Evidence of Iridescence Among Amphibians
Austral Ecology, Volume 51, Issue 7, July 2026.ABSTRACT Iridescence is a striking optical phenomenon observed in some animals whereby colour or reflectivity changes based on viewing angle, such that two observers in different locations may simultaneously perceive the same tissue differently. Among amphibians, there is limited photographic evidence of tissues displaying colour shifts that define ...
