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.

Morphological and Histometric Alterations in Gonadal and Neural Tissues of Native and Non-Native Fishes From the Lower Doce River Basin in Southeastern Brazil. [PDF]

Anat Histol Embryol
ABSTRACT The ichthyofauna of the lower Doce River basin has been exposed to multiple anthropogenic stressors. Among these, the collapse of the Fundão mining tailings dam in Mariana, Minas Gerais, Brazil, in 2015 resulted in massive fish mortality and widespread contamination of aquatic environments.

Osteology of the cranium and Weberian apparatus of African catfish families (Teleostei: Ostariophysi: Siluriformes) with an assessment of Palaeogene genera

Vertebrate Anatomy, Morphology, Palaeontology, 2022
Although the vast majority of fossil catfish material is isolated elements such as fin spines, a number of fossil catfishes (Siluriformes) have been named based on articulated crania from Palaeogene formations of Africa.

Actively soniferous tropical reef fishes are diverse, vulnerable, and valuable. [PDF]

J Fish Biol
Abstract Active (i.e., intentional) fish sound production provides informative cues for numerous ecological functions, including larval recruitment or reproduction, and can facilitate monitoring and restoration. It is therefore important to have a holistic picture of actively soniferous tropical reef fish diversity, particularly in the face of growing ...
