In the version of this Article originally published, references were missing from the column “Source(s) for mating and parental care system data” in Supplementary Table 1. The following references have now been added to the relevant species: Brichard 1989 has been added to Chalinochromis popelini, Chalinochromis brichardi and Julidochromis dickfeldi; Clabaut et al. 2007 to Altolamprologus calvus and Julidochromis regani; Konings 1998 to Neolamprologus hecqui; and Kuwamura 1997 to Chalinochromis ...

AbstractAnimals are bombarded with information about their environment and must select and interpret the relevant cues to make behavioral adjustments critical to survival. How animals integrate and balance the many signals they receive about their environment is rarely assessed. We investigated how signals from the social and physical environment interact to influence environmental preferences in the endemic Tanganyikan cichlid Neolamprologus pulcher. Specifically, we explored how fish respond t...

Social living has evolved numerous times across a diverse array of animal taxa. An open question is how the transition to a social lifestyle has shaped, and been shaped by, the underlying neurohormonal machinery of social behaviour. The nonapeptide neurohormones, implicated in the regulation of social behaviours, are prime candidates for the neuroendocrine substrates of social evolution. Here, we examined the brains of eight cichlid fish species with divergent social systems, comparing the numbe...

Physiologically, oxidative stress is considered a homeostatic imbalance between reactive oxygen species production and absorption. From an ecological perspective, oxidative stress may serve as an important constraint to life history traits such as lifespan, reproduction, and the immune system, and is gaining interest as a potential mechanism underlying life history trade-offs. Of late, there has been much interest in understanding the role of oxidative stress in the ecology of wild animals, part...

AbstractElectric fish handling gloves (FHGs) have been developed to immobilize fish during handling, with the potential benefit of reducing the time needed for sedation and recovery of fish relative to chemical anaesthetics. We examined the secondary stress responses (i.e., hematocrit, blood glucose, lactate, and pH) and reflex responses of Largemouth Bass Micropterus salmoides that were immobilized in water using electric FHGs for multiple durations (0, 30, and 120 s) relative to fish that were...

The evolutionary transition to cooperative breeding often involves high levels of monogamy and therefore indirect fitness benefits to helpers. Here, an alternative pathway is shown for cichlid fishes, involving direct fitness benefits derived from ecological factors such as group living.

Infanticide and offspring cannibalism are taxonomically widespread phenomena. In some group-living species, a new dominant individual taking over a group can benefit from infanticide if doing so in...
