Negative Phonotaxis Behavior of Juvenile Grass Carp (Ctenopharyngodon idella) to Different Acoustic Stimuli in Natural Aquatic Environments [PDF]

Animals
Hydraulic engineering structures can threaten freshwater fish by entraining them into hazardous areas. Acoustic barriers have been proposed as a non-physical method to guide fish away from these zones.

RNA-Sequencing Analysis of Gene-Expression Profiles in the Dorsal Gland of Alligator sinensis at Different Time Points of Embryonic and Neonatal Development [PDF]

Life, 2022
Significant advances have been made in the morphological observations of the dorsal gland (DG), an oval organ/tissue which lies on both sides of the dorsal midline of the crocodilian.

Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha. [PDF]

J Anat
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

Multi‐Omics Analysis of Gut Microbiome and Host Metabolism in Different Populations of Chinese Alligators (alligator sinensis) During Various Reintroduction Phases [PDF]

Ecology and Evolution
Reintroduction plays a significant role in the self‐maintenance and reconstruction of wild animal populations, serving as a communication bridge between captive and wild animals.

Comparative endocranial anatomy in the crocodylians Leidyosuchus canadensis and Stangerochampsa mccabei from the upper Cretaceous of Alberta, Canada. [PDF]

J Anat
Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.

Integrated analysis of lncRNA-miRNA-mRNA networks reveals stage-specific molecular regulation of oogenesis in Chinese alligator (Alligator sinensis) [PDF]

BMC Genomics
Background Reptiles, as the earliest vertebrate group to fully adapt to terrestrial environments, have reproductive strategies that hold critical significance for understanding biological evolution and ecological adaptation.

Dynamic changes in chromatin accessibility reveal the role of NF-Y targeting AURKB in mediating cell cycle during asynchronous oogenesis in the Chinese Alligator (Alligator sinensis) [PDF]

Frontiers in Zoology
The dynamics of chromatin accessibility that regulate oogenesis for the establishment of the female ovarian reserve in mammals have not been explored in reptiles with lifelong continuous oogenesis.

Roars, Rumbles, and Resonance: A Systematic Review and Meta-Analysis of Crocodylian Acoustic Signals. [PDF]

Ecol Evol
Crocodylians are highly vocal reptiles, possessing a complex acoustic signalling system including vocal and non‐vocal signals used for courtship, mating, mediating conflict, and providing maternal care. Despite this, research on crocodylian acoustic signalling remains infrequent, with methodologies and terminology varying widely across studies.

Identification of suitable habitats and priority conservation areas under climate change scenarios for the Chinese alligator (Alligator sinensis) [PDF]

Ecology and Evolution
Amphibians and reptiles, especially the critically endangered Chinese alligators, are vulnerable to climate change. Historically, the decline in suitable habitats and fragmentation has restricted the distribution of Chinese alligators to a small area in ...
