Diversity of the southern Africa Lacustricola Myers, 1924 and redescription of Lacustricola johnstoni (Günther, 1894) and Lacustricola myaposae (Boulenger, 1908) (Cyprinodontiformes, Procatopodidae) [PDF]

ZooKeys, 2020
Through the analysis of a comprehensive database of COI sequences, with the sequencing of 48 specimens, a first insight into the genetic diversity, distribution and relationships between the southern Africa “Lacustricola” species is presented.

Ganoderma lucidum aqueous extract inducing PHGPx to inhibite membrane lipid hydroperoxides and regulate oxidative stress based on single-cell animal transcriptome

Scientific Reports, 2022
In this study, the single-cell eukaryotic model organism Tetrahymena thermophila was used as an experimental material to reveal the anti-aging mechanism of Ganoderma lucidum aqueous extract. After treatment with the G.

Pseudobarbus outeniqua sp. nov., a new redfin species (Teleostei, Cyprinidae) from the Cape Fold Ecoregion of South Africa [PDF]

ZooKeys
Previous DNA-based studies identified four genetic lineages within Pseudobarbus afer: (i) the Mandela lineage confined to the Sundays, Swartkops, and Baakens river systems, (ii) the Krom lineage endemic to the Krom River system, (iii) the St Francis ...

Unintended consequences of using alien fish for human benefit in protected areas

Koedoe: African Protected Area Conservation and Science, 2015
There is increasing pressure on conservation agencies to allow access to natural resources within protected areas for human benefit. Alien fishes are often seen as a convenient resource because their harvest does not conflict with conservation goals ...

Impacts of non-native fishes under a seasonal temperature gradient are forecasted using functional responses and abundances [PDF]

NeoBiota, 2019
Developing predictive methods to forecast the impacts of existing and emerging invasive species is of critical importance to biodiversity conservation. However, invader impacts are context-dependent, making reliable and robust predictions challenging. In

Variation of blubber thickness of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) in human care: Adaptation to environmental temperature

Water Biology and Security, 2023
Blubber thickness (BT) has a seasonal pattern in most small cetaceans in temperate and polar regions, which may be a crucial adaptive mechanism in response to environmental temperature changes.
