Description of Encephalon Morphology of Nile Tilapia Oreochromis niloticus (Linnaeus, 1758) (Perciformes: Cichlidae) From Brazil. [PDF]

Anat Histol Embryol
ABSTRACT The Nile tilapia (Oreochromis niloticus) is a cichlid species native to Africa and is widely farmed in tropical and subtropical regions around the world, making it one of the most commercially important aquaculture species. Despite its significance, there is still a lack of detailed anatomical descriptions of its brain.

Extremely Small Clutch Size and Juvenile Survival in a Social Cichlid of an African Great Lake. [PDF]

Ecol Evol
Neolamprologus buescheri, a cooperatively breeding cichlid fish endemic to Lake Tanganyika, exhibits one of the slowest life histories documented among teleost fish. With remarkably small clutch sizes ranging from one to seven eggs (median = 3) and exceptionally high juvenile survival rates of over 50% within two months, this species deviates ...

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River. [PDF]

Conserv Biol
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Use of Citizen Science to Determine Prey Partitioning Between Two Coastal Raptors. [PDF]

Ecol Evol
In Australia, Eastern Osprey (Pandion haliaetus cristatus) and White‐bellied Sea‐Eagle (Haliaeetus leucogaster) occupy the same ecological niche and are suspected of partitioning prey resources. This study investigated this through evaluating the breadth, overlap and partitioning of diets recorded from social media posts.

The Early Development of the Blue-Eye Cichlid, Cryptoheros spilurus (Cichliformes: Cichlidae). [PDF]

Evol Dev
We document the early development of Cryptoheros spilurus, highlighting rapid cranial differentiation, sensory organ formation, and fin development. Ontogenetic allometry and ultrastructural traits reveal functional adaptations for early foraging and locomotion, offering insights into ecological success and the developmental basis of cichlid ...
