Consideration of signal detection theory shows how decision ecology relates to optimal collective decisions, helping explain the prevalence of quorum-sensing in even the simplest collective systems, such as bacterial communities.

In the context of an organism's ecology, physiology, and macroevolutionary history, inheritance and gene loss can yield emergent patterns of trait variability that give the appearance of gene acquisition.
UV-reflective dragonfly wax is shown to consist of very long-chain methyl ketones and aldehydes, and a synthetic dragonfly wax spontaneously forms light-scattering fine structures with strong UV reflection.

When ancestral Xenopus returned to water ~170mya, they evolved a new method for producing courtship calls underwater without airflow, using vibrations that also preserve essential acoustic information on species identity.
The turquoise killifish from ephemeral pools in African savannah combines extremely short lifespan with a standard vertebrate body plan – ideal attributes for a laboratory animal.
Empirical evidence shows that conserving local plant diversity is a robust strategy to maintain multiple valuable ecosystem services provided by soils in both present and future environmental conditions.

In years with colder ocean temperatures, fur seal pups receive more maternal care and have a better energy balance, clearing hookworm infection earlier, which increases their chances of survival.

At Cuatro Ciénegas, the ancestral niche conditions of the ancient shores of Laurentia persisted along with its microbial communities that have been coevolving for a very long time.

Domestication of endosymbiotic Mollicutes may have resolved nitrogen-recycling challenges for attine ants and enabled the evolutionary derived leaf-cutting ants to fully exploit their herbivorous niches.
