DOI: 10.1002/ece3.8383
Abstract: Abstract Exaggerated secondary sexual characteristics are apparently costly and seem to defy natural selection. This conundrum promoted the theory of sexual selection. Accordingly, exaggerated secondary sexual characteristics might be ornaments on which female choice is… read more here.

DOI: 10.1016/j.anbehav.2018.03.003
Abstract: Although the consumption of one's own offspring is often viewed as maladaptive, under some circumstances this behaviour can be a beneficial way to terminate parental care. When the costs of providing care are extremely high… read more here.

Parental care and neuropeptide dynamics in a cichlid fish Neolamprologus caudopunctatus

DOI: 10.1016/j.yhbeh.2019.104576
Abstract: The hypothalamic neuropeptides arginine vasopressin (AVP) and oxytocin (OT) modulate social behavior across a wide variety of species. However, the role of arginine vasotocin (AVT) and isotocin (IT, the teleost homologs of AVP and OT)… read more here.

A Kiss of Deep Homology: Partial Convergence in the Genomic Basis of Hypertrophied Lips in Cichlid Fish and Human Cleft Lip

DOI: 10.1093/gbe/evad072
Abstract: Abstract The genomic loci generating both adaptive and maladaptive variation could be surprisingly predictable in deeply homologous vertebrate structures like the lips. Variation in highly conserved vertebrate traits such as the jaws and teeth in… read more here.

DOI: 10.1111/jfb.14836
Abstract: Group living is widespread in animals and many fishes form shoals. Examining within-group interactions in fishes may contribute to the general understanding of dynamic social structures in animals. The sex ratio of a group has… read more here.
