Bioluminescence spans all oceanic dimensions and has evolved many times—from bacteria
to fish—to powerfully influence behavioral and ecosystem dynamics. New methods and …

Our view of the evolution of sexually selected traits and preferences was influenced radically
in the 1990s by studies that emphasized how signals interact with sensory properties of …

Birds are highly visual animals with complex visual systems. In this article, we discuss the
spectral characteristics and genetic mechanisms of the spectral tuning of avian visual …

It has been 25 years since the formalization of the Sensory Drive hypothesis was published
in the American Naturalist (1992). Since then, there has been an explosion of research …

Although private communication is considered an important diversifying force in evolution,
there is little direct behavioural evidence to support this notion. Here, we show that …

The role of selection in speciation is a central yet poorly understood problem in evolutionary
biology. The rapid radiations of extremely colorful cichlid fish in African lakes have fueled the …

Sensory systems provide crucial information about an organism's external environment and,
thus, are often subject to strong natural selection. Because of the large variation in the …

Unidirectional elaboration of male trait evolution (eg, larger, brighter males) has been
predicted by receiver bias models of sexual selection and empirically tested in a number of …

Cichlid fish inhabit a diverse range of environments that vary in the spectral content of light
available for vision. These differences should result in adaptive selective pressure on the …

Midas cichlid fish are a Central American species flock containing 13 described species that
has been dated to only a few thousand years old, a historical timescale infrequently …
