Ontogeny of the osteocranium in the African catfish, Clarias gariepinus Burchell (1822) (Siluriformes: Clariidae): Ossification sequence as a response to functional demands
TLDR
The ontogeny of the bony skull of the African catfish, Clarias gariepinus, is studied from initial ossification until a complete skull is formed, which seems to be related to the functional demands that arise in a developing larva.
Modulation and variability of prey capture kinematics in clariid catfishes.
TLDR
The results indicate that the narrow dietary breadth of trophic specialists is indeed indicative of functional stereotypy in this group of fishes.
No trade-off between biting and suction feeding performance in clariid catfishes
TLDR
The results demonstrate the possibility for catfishes to increase bite performance considerably without compromising suction performance, and demonstrate the dominant role of ventral expansion for producing suction in these fish.
A functional morphological approach to the scaling of the feeding system in the African catfish, Clarias gariepinus
TLDR
An analysis of the consequences of the observed changes in morphology with size on performance traits, including bite force and jaw closing velocity, suggests a tight link between the scaling of the feeding system and the natural diet of these fish.
Morphological abnormalities in African catfish (Clarias gariepinus) larvae exposed to malathion.
TLDR
The results suggested that the vertebral deformities observed in the fish which have been exposed to malathion from the notochord-stage onwards were the result of a deformedNotochord instead of the deformation of the vertebra elements themselves.
Effects of 17α-ethinylestradiol on sexual development of the amphipod Hyalella azteca
TLDR
Evidence is provided that sexual development of H. azteca is affected by exposure to sublethal concentrations of EE, and the sex ratio of the populations exposed to EE for more than two generations tended, although not statistically significantly, to be in favor of females.
Biting Performance in Teeth‐Digging African Mole‐Rats (Fukomys, Bathyergidae, Rodentia)*
TLDR
This study studied interspecific differences in bite performance among three taxa, in relation to their skull anatomy and skull shape, to analyze the evolutionary pattern behind the variation in structure and performance of the biting apparatus in Fukomys mole‐rats.
It is all in the head : morphological basis for differences in bite force among colour morphs of the Dalmatian wall lizard
TLDR
Differences in bite performance among morphs are caused specifically by an increase in the mass of the jaw adductor, which may be induced by differences in circulating hormone levels.
