Cryptobia iubilans in Cichlids

open access: yesEDIS, 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 ...

A Phylogenetic Index for Cichlid Microsatellite Primers [PDF]

open access: yesInternational Journal of Zoology, 2010
Microsatellites abound in most organisms and have proven useful for a range of genetic and genomic studies. Once primers have been created, they can be applied to populations or taxa that have diverged from the source taxon. We use PCR amplification, in a 96-well format, to determine the presence and absence of 46 microsatellite loci in 13 cichlid ...

Back to Tanganyika: a case of recent trans-species-flock dispersal in East African haplochromine cichlid fishes [PDF]

open access: yesRoyal Society Open Science, 2015
The species flocks of cichlid fishes in the East African Great Lakes are the largest vertebrate adaptive radiations in the world and illustrious textbook examples of convergent evolution between independent species assemblages.

Gene duplication in an African cichlid adaptive radiation [PDF]

open access: yes, 2014
Background Gene duplication is a source of evolutionary innovation and can contribute to the divergence of lineages; however, the relative importance of this process remains to be determined.

Ancient Hybridisation Fuelled Diversification in Acropora Corals

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Introgression is the infiltration or flow of genes from one species to another through hybridisation followed by backcrossing. This may lead to incorrect phylogenetic reconstruction or divergence‐time estimation. Acropora is a dominant genus of reef‐building corals; however, whether this group has an introgression history before their ...

Metabolic adjustments in Satanoperca aff. jurupari (Perciformes: Cichlidae)

open access: yesGenetics 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

Sex group composition, social interaction, and metabolism in the fish Nile tilapia

open access: yesBrazilian Journal of Biology
We tested whether the fish Nile tilapia (Oreochromis niloticus) in a monosex male group spends more energy and displays an agonistic profile, differently from males in male-female groups.

Conservation and sustainable utilization of Nigerian ornamental fishes [PDF]

open access: yes, 2005
The paper assessed qualitatively the threat status of nigerian freshwater fishes that are presently being exported and those that have potential in aquarium trade using such criteria as rarity, size at maturity, mode of reproduction, human population ...

Genome Architecture and Speciation in Plants and Animals

open access: yesMolecular Ecology, EarlyView.
ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.

Convict cichlids benefit from close proximity to another species of cichlid fish [PDF]

open access: yesBiology 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.
