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

, 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 ...

Various Modes of Spinal Cord Injury to Study Regeneration in Adult Zebrafish

Bio-Protocol, 2016
Spinal cord injury (SCI) in mammals leads to failure of both sensory and motor functions, due to lack of axonal regrowth below the level of injury as well as inability to replace lost neural cells and to stimulate neurogenesis.

Compressive stress gradients direct mechanoregulation of anisotropic growth in the zebrafish jaw joint.

PLoS Computational Biology
Mechanical stimuli arising from fetal movements are critical factors underlying joint growth. Abnormal fetal movements negatively affect joint shape features with important implications for joint health, but the mechanisms by which mechanical forces from

Population Genetic Structure and Genetic Diversity in Twisted-Jaw Fish, Belodontichthys truncatus Kottelat & Ng, 1999 (Siluriformes: Siluridae), from Mekong Basin

International Journal of Zoology, 2017
The Mekong River and its tributaries possess the second highest diversity in fish species in the world. However, the fish biodiversity in this river is threatened by several human activities, such as hydropower plant construction.

Effects of nicotine exposure on murine mandibular development.

PLoS ONE, 2019
Nicotine is known to affect cell proliferation and differentiation, two processes vital to proper development of the mandible. The mandible, the lower jaw in mammals and fish, plays a crucial role in craniofacial development.

Novel adverse outcome pathways revealed by chemical genetics in a developing marine fish

eLife, 2017
Crude oil spills are a worldwide ocean conservation threat. Fish are particularly vulnerable to the oiling of spawning habitats, and crude oil causes severe abnormalities in embryos and larvae.

Occurrence of Clinostomum Metacercariae in Oreochromis mossambicus from Mashoko Dam, Masvingo Province, Zimbabwe

Scientifica, 2018
Mashoko Dam is in Ago-ecological Region 4 in Zimbabwe. Five sampling sites were randomly selected and each site was sampled twice per month, for six months. A total of 180 Oreochromis mossambicus fish (101 females and 79 males) were caught. The fish were
