Modular genetic control of social status in a cichlid fish

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance Social rank along a hierarchy determines physiological state and behavioral performance. A ubiquitous feature of social hierarchies is the communication of rank through nonphysical signaling systems (e.g., coloration) and aggression, traits ...

Foraging environment determines the genetic architecture and evolutionary potential of trophic morphology in cichlid fishes [PDF]

open access: yes, 2016
Phenotypic plasticity allows organisms to change their phenotype in response to shifts in the environment. While a central topic in current discussions of evolutionary potential, a comprehensive understanding of the genetic underpinnings of plasticity is

Genome editing in East African cichlids and tilapias: state-of-the-art and future directions

open access: yesOpen Biology, 2023
African cichlid fishes of the Cichlidae family are a group of teleosts important for aquaculture and research. A thriving research community is particularly interested in the cichlid radiations of the East African Great Lakes. One key goal is to pinpoint

Hybridisation generates a hopeful monster: a hermaphroditic selfing cichlid [PDF]

open access: yes, 2016
Compared to other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes.

On the measurement of ecological novelty: scale-eating pupfish are separated by 168 my from other scale-eating fishes. [PDF]

open access: yes, 2013
The colonization of new adaptive zones is widely recognized as one of the hallmarks of adaptive radiation. However, the adoption of novel resources during this process is rarely distinguished from phenotypic change because morphology is a common proxy ...

Invasive cichlids (Teleostei: Cichliformes) in the Amacuzac River, Mexico: Implications for the behavioral ecology of the native Mexican mojarra Amphilophus istlanus

open access: yesWater Biology and Security, 2023
The introduction of species is a leading cause of biodiversity loss and habitat alteration. Several species have invaded Mexican freshwater ecosystems, adversely affecting native fishes.

The Value of Comparative Animal Research : Krogh’s Principle Facilitates Scientific Discoveries [PDF]

open access: yes, 2017
There are no conflicts of interest to declare. This paper developed from the 2016 Early Career Impact Award from the Federation of Associations in Behavioral & Brain Sciences to TJS. TJS has received funding from The Leverhulme Trust.

Predator avoidance in extremophile fish [PDF]

open access: yes, 2013
Extreme habitats are often characterized by reduced predation pressures, thus representing refuges for the inhabiting species. The present study was designed to investigate predator avoidance of extremophile populations of Poecilia mexicana and P ...

Cytoarchitecture of a Cichlid Fish Telencephalon [PDF]

open access: yesBrain, Behavior and Evolution, 2009
Although the telencephalon of ray-finned fishes has garnered considerable attention from comparative neuroanatomists, detailed descriptions of telencephalic organization are available for only a few species. This necessarily limits our understanding of telencephalic evolution, particularly in light of the extraordinary diversity of ray-finned fishes ...

Effects of different sampling intervals on apparent protein and energy digestibility of common feed ingredients by juvenile oscar fish (Astronotus ocellatus)=Diferentes intervalos de coleta na determinação da digestibilidade aparente da proteína e da energia de ingredientes comuns para o apaiari (Astronotus ocellatus) [PDF]

open access: yesActa Scientiarum: Animal Sciences, 2012
This study evaluated the apparent protein and energy digestibility of common feed ingredients (soybean meal, fish meal, wheat meal and corn) by juvenile oscars using two different sampling intervals (30 min. and 12h).
