Impacts of predator odours and conspecific disturbance cues on minnow thermal tolerance
Journal of Fish Biology, EarlyView.Abstract Warming waters can affect fish community dynamics, potentially exacerbating predator–prey asymmetries in behavioural and physiological metrics of thermal tolerance. Further, differing responses of prey fish species to concurrent predation risk and warming highlight the need to understand these impacts in various contexts, especially with at ...

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.

Metabolic adjustments in Satanoperca aff. jurupari (Perciformes: Cichlidae)
Genetics and Molecular Biology, 2003 In this paper, we describe the enzyme levels and isozyme distribution in skeletal and heart muscle of Satanoperca aff. jurupari, (Cichlidae, subgroup Geophaginae). LDH and CS were measured in skeletal and heart muscle. Starch gel electrophoresis was used

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.

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).

Cichlids: A Host of Opportunities for Evolutionary Parasitology
Trends in Parasitology, 2016 Thanks to high species diversity and a broad range of speciation mechanisms, cichlid fishes represent a textbook model in evolutionary biology. They are also of substantial economic value. Despite this importance, cichlid parasites remain understudied, although some are more diverse than their hosts.

Lateralization of lateral displays in convict cichlids [PDF]
Biology Letters, 2011 We examine lateralization of lateral displays in convict cichlids, Amatitlania nigrofasciata , and show a population level preference for showing the right side. This enables contesting pairs of fish to align in a head-to-tail posture, facilitating other activities.

Cloning and characterisation of gonadotropin-releasing hormone (GnRH) receptors in the cichlid (Haplochromis burtoni) and the zebrafish (Danio rerio) [PDF]
, 2003 Bibliography: leaves 75-89.The identification of multiple forms of gonadotropin-releasing hormone (GnRH) in a single species is becoming a common occurrence.

Cryptobia iubilans in Cichlids
EDIS, 2014 After many years of diagnostics at the University of Florida and at other laboratories around the country, it appears that Cryptobia iubilans is not uncommon among cichlids, and that environmental and other factors determine the extent of disease. This revised 3-page fact sheet was written by Ruth Francis-Floyd and Roy Yanong, and published by the UF ...

eLifeCichlid fishes inhabiting the East African Great Lakes, Victoria, Malawi, and Tanganyika, are textbook examples of parallel evolution, as they have acquired similar traits independently in each of the three lakes during the process of adaptive radiation.
