Hierarchical Interaction between Food Diversity and Competition in Brackish Fish Species in South Korea

open access: yesFishes, 2023
Information about the food sources for fish is important not only for predation and food competition, but also for the direct impact on organism interactions, relationships, and biodiversity within aquatic ecosystems.

The early diversification of ray‐finned fishes (Actinopterygii): hypotheses, challenges and future prospects

open access: yesBiological Reviews, 2022
ABSTRACTActinopterygii 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.

Preferential accumulation of sex and Bs chromosomes in biarmed karyotypes by meiotic drive and rates of chromosomal changes in fishes

open access: yesAnais da Academia Brasileira de Ciências, 2014
Mechanisms of accumulation based on typical centromeric drive or of chromosomes carrying pericentric inversions are adjusted to the general karyotype differentiation in the principal Actinopterygii orders. Here, we show that meiotic drive in fish is also

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene-Edited Xenopus Tadpoles. [PDF]

open access: yesJ Pineal Res
ABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.
