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.

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 ...

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil. [PDF]
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

The early diversification of ray-finned fishes (Actinopterygii): hypotheses, challenges and future prospects. [PDF]
ABSTRACT Actinopterygii makes up half of living vertebrate diversity, and study of fossil members during their Palaeozoic rise to dominance has a long history of descriptive work. Although research interest into Palaeozoic actinopterygians has increased in recent years, broader patterns of diversity and diversity dynamics remain critically understudied.

New Cretaceous lungish material from southern South America, Argentina [PDF]
Dipnoi is a large group of sarcopterygians which ranges from the Early Devonian to the present. Traditionally, it was considered that their taxonomic diversity decreased at the end of Paleozoic.

General principles for assignments of communities from eDNA: Open versus closed taxonomic databases
The collection of environmental DNA (eDNA) from water has revolutionized biodiversity assessments and enables the detection of rare and invasive species.To ensure that biodiversity is accurately detected and identified in metabarcoding studies, we must guarantee key steps in bioinformatic pipelines, and use suitable and accurate sequence reference ...
