Identification, characterization, and function of GRP94 and HSP90β in cold stress response in cold water fish Phoxinus lagowskii

open access: yesAquaculture Reports, 2023
The glucose-regulated protein (GRP94) and HSP90β are highly conserved and diverse molecular chaperones that could prevent protein aggregation and denaturation while also playing an important role in cellular stress responses.

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

open access: yesThe Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Biodiversity of aquatic fungi in China

open access: yesMycology, 2013
Aquatic fungi include those that occur in freshwater, marine, and brackish water habitats. In China, aquatic fungi have been investigated since 1920s. In this paper, we summarized the known data and provided a comprehensive list of aquatic fungi in China.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

open access: yesThe Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

A Reassessment of Phylogenetic Relationships in Class Oligohymenophorea (Protista, Ciliophora) Based on Updated Multigene Data

open access: yesEcology and Evolution
Within the ciliate class Oligohymenophorea, many evolutionary relationships among taxa remain unresolved. This study incorporates 97 new sequences from 30 oligohymenophorean populations, including nuclear small subunit ribosomal (SSU‐rRNA) genes, nuclear

Biodiversity Conservation of Aquatic Ecosystems

open access: yes, 2022
Freshwater systems are among the most endangered biomes globally. Drivers and pressures include an increased demand for food, energy and water, expansion of urban areas that leads to changes in hydrology and water chemistry, as well as climate change which acts as overarching threat interacting with multiple aspects of the ecosystem.

Aquatic eDNA for monitoring French Guiana biodiversity [PDF]

open access: yesBiodiversity Data Journal, 2019
Environmental DNA [eDNA] metabarcoding has recently emerged as a non-destructive alternative to traditional sampling for characterising species assemblages. We here provide a consistent dataset synthetising all eDNA sampling sites in French Guiana to date. Field collections have been initiated in 2014 and have continued until 2019.

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II

open access: yesThe Anatomical Record, EarlyView.
Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.

A redescription and two new descriptions of gnathiid isopods (Isopoda, Gnathiidae) from South African museum collections (1898–1976) [PDF]

open access: yesZooKeys
Museum collections continue to play a critical role in taxonomic research by preserving historical material and biodiversity records that might otherwise have been lost.
