A Species of Reef Fish that Uses Ultraviolet Patterns for Covert Face Recognition
The evolutionary and behavioral significance of an animal's color patterns remains poorly understood [1-4], not least, patterns that reflect ultraviolet (UV) light [5]. The current belief is that UVExpand

Red fluorescence in reef fish: A novel signalling mechanism?
BackgroundAt depths below 10 m, reefs are dominated by blue-green light because seawater selectively absorbs the longer, 'red' wavelengths beyond 600 nm from the downwelling sunlight. Consequently,Expand

Bateman Gradients in Hermaphrodites: An Extended Approach to Quantify Sexual Selection
Sexual selection is often quantified using Bateman gradients, which represent sex‐specific regression slopes of reproductive success on mating success and thus describe the expected fitness returnsExpand

Multiple mating affects offspring size in the opisthobranch Chelidonura sandrana
Offspring size can have pervasive effects throughout the life history stages of many marine invertebrates. Although maternal offspring investment is largely determined by the environmental conditionsExpand

Natural female mating rate maximizes hatchling size in a marine invertebrate.
1. Males and females often differ in their optimal mating rates, resulting potentially in conflicts over remating. In species with separate sexes, females typically have a lower optimal mating rateExpand

Fairy wrasses perceive and respond to their deep red fluorescent coloration
Fluorescence enables the display of wavelengths that are absent in the natural environment, offering the potential to generate conspicuous colour contrasts. The marine fairy wrasse CirrhilabrusExpand

Red fluorescence increases with depth in reef fishes, supporting a visual function, not UV protection
Why do some marine fishes exhibit striking patterns of natural red fluorescence? In this study, we contrast two non-exclusive hypotheses: (i) that UV absorption by fluorescent pigments offersExpand

The role of body size in early mating behavior in a simultaneous hermaphrodite, Chelidonura sandrana
Intraspecific variation in mating behavior is widespread among simultaneous hermaphrodites but its underlying sources remain largely unexplored. In the sea slug Chelidonura sandrana, most matings areExpand

Population density and group size effects on reproductive behavior in a simultaneous hermaphrodite
BackgroundDespite growing evidence that population dynamic processes can have substantial effects on mating system evolution, little is known about their effect on mating rates in simultaneousExpand

You eat what you are: personality‐dependent filial cannibalism in a fish with paternal care
Abstract Many animal parents invest heavily to ensure offspring survival, yet some eventually consume some or all of their very own young. This so‐called filial cannibalism is known from a wide rangeExpand
