Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Cichlids and stingrays can add and subtract ‘one’ in the number space from one to five

open access: yesScientific Reports, 2022
The numerical understanding of cichlids and stingrays was examined regarding addition and subtraction abilities within the number space of one to five. Experiments were conducted as two-alternative forced-choice experiments, using a delayed matching to ...

Cichlid genome modification - Malawi cichlids v1

open access: yes, 2023
Here we provide a microinjection protocol for the modification of cichlid fish via CRISPR or transgenesis. This is our forked version of the protocol provided by Scott Juntti (https://www.protocols.io/view/cichlid-genome-modification-cj5wuq7e), modified for our Lake Malawi cichlid species for both NHEJ knock-outs and HDR knock-ins These protocols ...

Microsatellites Cross-Species Amplification across Some African Cichlids [PDF]

open access: yes, 2012
The transfer of the genomic resources developed in the Nile tilapia, Oreochromis niloticus, to other Tilapiines sensu lato and African cichlid would provide new possibilities to study this amazing group from genetics, ecology, evolution, aquaculture, and

Evolutionary genetics of naturally and sexually selected traits in cichlid fishes [PDF]

open access: yes, 2014
In my PhD thesis I use cichlid fishes as model system to study the evolutionary genetics of naturally and sexually selected traits. Several traits of cichlid fishes such as; the pharyngeal jaw apparatus, haplochromine maternal mouthbrooding, egg-spots ...

Comparative ecology and phylogeography in east African cichild fishes [PDF]

open access: yes, 2014
Since almost two decades speciation outbursts, so-called adaptive radiations, have been put forward as a major reason for a large portion of the bio-diversity we see today.
