Mitochondrial genome annotation and phylogenetic placement of Oreochromis andersonii and O. macrochir among the cichlids of southern Africa. [PDF]

PLoS ONE, 2018
Genetic characterization of southern African cichlids has not received much attention. Here, we describe the mitogenome sequences and phylogenetic positioning of Oreochromis andersonii and O. macrochir among the African cichlids.

Bio‐ecological studies on two cichlids in the Brimsu reservoir of Ghana

Aquaculture, Fish and Fisheries, 2023
Although small‐scale fisheries and aquaculture provide opportunities to increase fish yield to supplement rural food and income, they remain undeveloped in Ghana.

Testing the performance of environmental DNA metabarcoding for surveying highly diverse tropical fish communities: A case study from Lake Tanganyika

Environmental DNA, 2020
Background and Aims Environmental DNA (eDNA) metabarcoding provides a highly sensitive method of surveying freshwater fish communities, although studies to date have largely been restricted to temperate ecosystems.

Assessing the dietary sources of two cichlid species in River Nile sub-branches: Stomach contents, fatty acids and stable isotopes analyses

Egyptian Journal of Aquatic Research, 2016
We assess the importance of four different food sources as dietary components of Oreochromis niloticus and Sarotherodon galilaeus in Nile sub-branches using stomach contents, fatty acids (FA) and stable isotopes (SI) analyses.

Evolutionary divergence of 3’ UTRs in cichlid fishes

BMC Genomics, 2018
Background Post-transcriptional regulation is crucial for the control of eukaryotic gene expression and might contribute to adaptive divergence. The three prime untranslated regions (3’ UTRs), that are located downstream of protein-coding sequences, play

Biological Diversity and Resilience: Lessons from the Recovery of Cichlid Species in Lake Victoria

Ecology and Society, 2011
A fundamental feature of the Anthropocene is the inexorable erosion of the self-repairing capacity or adaptive renewal of natural systems because of natural perturbation, exploitation, or management failure.

Elaboration, development, and installation of the first animal skin bank in Brazil for the treatment of burns and wounds [PDF]

Revista Brasileira de Cirurgia Plástica, 2019
Introduction: The production and distribution of human skin by Brazilian skin banks is insufficient to meet the country's demand, supplying less than 1% of the need for treating burn victims.

Lateral line morphology, sensory perception and collective behaviour in African cichlid fish

Royal Society Open Science, 2023
The lateral line system of fishes provides cues for collective behaviour, such as shoaling, but it remains unclear how anatomical lateral line variation leads to behavioural differences among species.

Assessment of fighting ability in the vocal cichlid Metriaclima zebra in face of incongruent audiovisual information

Biology Open, 2019
Information transfer between individuals typically depends on multiple sensory channels. Yet, how multi-sensory inputs shape adaptive behavioural decisions remains largely unexplored.

Strong biomechanical relationships bias the tempo and mode of morphological evolution

eLife, 2018
The influence of biomechanics on the tempo and mode of morphological evolution is unresolved, yet is fundamental to organismal diversification. Across multiple four-bar linkage systems in animals, we discovered that rapid morphological evolution (tempo ...
