Population Genetic Structure of Three Cichlids in Ilorin, North-Central Nigeria
The Iraqi Journal of Veterinary Medicine, 2022 Cichlids are among the economically important which serve as a source of food for people around the world. A deep understanding of the population structure and genetic diversity of cichlids are vital for initiation of conservation policies and

An Enhanced Soft‐Containing Gripper for Pick‐And‐Place of Oyster Products at Extreme Handling Speed
Journal of Field Robotics, EarlyView.ABSTRACT Soft robotic grippers have been developed for high‐speed handling of soft, fragile foods. For example, our previously designed soft‐containing gripper has been implemented on food production lines. However, existing soft robotic grippers remain inadequate for food pick‐and‐place tasks at extreme handling speeds (e.g., > 70 pcs/min).

Integrative Zoology, EarlyView.Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Hearing in the jewel cichlid [PDF]
The Journal of the Acoustical Society of America, 1982 An in-depth analysis of hearing sensitivity for the jewel cichlid, Hemichromis bimaculatus was made using neurophysiological techniques to measure sensitivity at various levels of the auditory system and psychophysical techniques to measure whole-system sensitivity. For physiological studies, fish were stimulated by sinusoids generated by a loudspeaker

Testing conjectures about morphological diversity in cichlids of Lakes Malawi and Tanganyika [PDF]
, 2005 The morphological diversity of Malawi and Tanganyika cichlids has often been qualitatively described, but rarely have hypotheses based on these descriptions been tested empirically.
