The cranial endocast of Dipnorhynchus sussmilchi (Sarcopterygii: Dipnoi) and the interrelationships of stem-group lungfishes [PDF]
The first virtual cranial endocast of a lungfish from the Early Devonian, Dipnorhynchus sussmilchi, is described. Dipnorhynchus, only the fourth Devonian lungfish for which a near complete cranial endocast is known, is a key taxon for clarifying ...

Morphometric analysis of lungfish endocasts elucidates early dipnoan palaeoneurological evolution [PDF]
The lobe-finned fish, lungfish (Dipnoi, Sarcoptergii), have persisted for ~400 million years from the Devonian Period to present day. The evolution of their dermal skull and dentition is relatively well understood, but this is not the case for the ...

Morphology and histology of the olfactory organ of two African lungfishes, Protopterus amphibius and P. dolloi (Lepidosirenidae, Dipnoi) [PDF]
The olfactory organs of two African lungfishes, Protopterus amphibius and P. dolloi, were investigated using a stereo microscope and a compound light microscope and were described anatomically, histologically, and histochemically.

The evo-devo origins of the nasopharynx. [PDF]
Abstract The process by which upper respiratory tract structures have changed over deep evolutionary time is, in part, reflected in the process of embryologic development. The nasopharynx in particular is a centrally located space bounded by components of the respiratory portion of the nasal cavity, cranial base, soft palate, and Eustachian tube.

A new lungfish (Ceratodontoidei, Dipnoi) from the Early Jurassic of Chongqing, China [PDF]
Dipnoi (lungfishes) are a group of air-breathing sarcopterygian fishes that survived over hundreds of millions of years and their crown members (Neoceratodus, Lepidosiren and Protopterus) are among the closest living relatives of the tetrapods. After the

A new origin of the ‘modern’ lungfish dentition revealed by taxonomic overlap between Devonian and Carboniferous dipnoans [PDF]
Lungfishes (Dipnoi, Sarcopterygii) initially radiated in the Early Devonian, and reached the apogee of their diversity during this period, especially with regard to their dentitions.

The cranial endocast of the Upper Devonian dipnoan ‘Chirodipterus’ australis [PDF]
One of the first endocasts of a dipnoan (lungfish) to be realised was that of the Upper Devonian taxon Chirodipterus australis. This early interpretation was based on observations of the shape of the cranial cavity alone and was not based on a natural ...

ErythroCite: a database on red blood cell size of fishes [PDF]
Size is a fundamental trait in biology, and cell size plays a key role in cellular functions, influencing physiological adaptations and evolutionary processes in living organisms. For decades, scientists have been fascinated by the considerable variation

Betaine Alleviated the Ammonia-Induced Apoptosis and Inflammation in the Skin of Largemouth Bass Fed With High-Carbohydrate Diet via Inhibiting MAPK/NFκB-Myd88 Pathway. [PDF]
Fish skin provides vital protection against environmental stressors and pathogens, whose health is significantly affected by dietary components. In intensive aquaculture, accumulated ammonia seriously affected fish skin structure and immune responses.

Quantitative Synthesis of Microbe-Driven Acclimation and Adaptation in Wild Vertebrates. [PDF]
ABSTRACT Microorganisms associated with animals harbour a unique set of functional traits pivotal for the normal functioning of their hosts. This realisation has led researchers to hypothesise that animal‐associated microbial communities may boost the capacity of their hosts to acclimatise and adapt to environmental changes, two eco‐evolutionary ...
