Journal of Fish Biology, EarlyView.Abstract A new species of pearl cichlid of the ‘Geophagus’ brasiliensis species group, endemic to the Piranga River, a major tributary of the upper Doce River basin in the state of Minas Gerais, southeastern Brazil, is herein described. The new species is delimited using an integrative approach, with molecular‐based species delimitation methods coupled

Production of chemical alarm cues in convict cichlids: the effects of diet, body condition and ontogeny [PDF]
, 2004 While much is known regarding the role of chemical alarm cues in the mediation of predator–prey dynamics within aquatic ecosystems, little is known regarding the production of these critically important information sources.

Journal of Fish Biology, EarlyView.Abstract Intensive multigenerational size‐selective mortality has been found to alter collective properties like shoaling via evolutionary adaptations of individual‐level behavioural traits. For example, experimental populations of zebrafish (Danio rerio) experiencing intensive large size‐selective mortality over multiple generations developed less ...

Serial monogamy benefits both sexes in the biparental convict cichlid [PDF]
PeerJ, 2019 Monogamy can be either long-term or serial, with new pairs formed with each breeding bout. Costs and benefits are associated with each strategy. Because biparental convict cichlids (Amatitlania nigrofasciata) typically switch mates, exhibiting serial ...

Bony fish genomes: Status and gaps
Journal of Fish Biology, EarlyView.Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

NaturaCichlids were given their name by the French zoologist Charles Lucien Bonaparte (1803-1857), a nephew of Napoleon, who borrowed the term from the Greek κίχλη (kichle), a word that in origin had the broad meaning of “wrasse” (a fish) or “thrush” (a bird).

Journal of Fish Biology, EarlyView.Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

Convict cichlids benefit from close proximity to another species of cichlid fish [PDF]
Biology Letters, 2008 The coexistence of species with overlapping resource use is often thought to involve only negative fitness effects as a consequence of interspecific competition. Furthermore, the scarce empirical research on positive species interactions has predominantly focused on sessile organisms.

Evolution of regulatory networks associated with traits under selection in cichlids
Genome Biology, 2021 Background Seminal studies of vertebrate protein evolution speculated that gene regulatory changes can drive anatomical innovations. However, very little is known about gene regulatory network (GRN) evolution associated with phenotypic effect across ...

Journal of Zoology, EarlyView.We explored age‐related cognitive decline in captive fawn‐footed mosaic‐tailed rats (Melomys cervinipes) using a novel object recognition task. Contrary to expectations, recognition memory did not decline with age, but recognition memory was lower in intermediate‐aged rats compared to both older and younger individuals.
