Complete mitochondrial cytochrome b gene sequences were determined from 12 species of the Australo-Papuan birds-of-paradise (Paradisaeidae) representing 9 genera. Phylogenetic analysis of these and 5 previously published sequences reveals a radiation of the main paradisaeinine lineages that took place over a relatively short evolutionary time scale. The core paradisaeinines are resolved as the ...

The mechanisms regulating mitochondrial outer-membrane permeabilization and the release of cytochrome c during apoptosis remain controversial. In the present study, we show in an in vitro model system that the release of cytochrome c may occur via moderate modulation of mitochondrial volume, irrespective of the mechanism leading to the mitochondrial swelling. In contrast with mitochondrial perm...

Mitochondria isolated from cysts of Artemia salina (brine shrimp) were found to be devoid of cristae and to possess a low respiratory capability. Hydration of the cysts induces marked biochemical and morphological changes in the mitochondria. Their biogenesis proceeds in two stages. The first stage is completed within 1 h and is characterized by a rapid increase in the respiratory capability of...

An integrative taxonomic analysis of species in the colubrid genus Lycodon Fitzinger, 1826 recovered two new syntopic L. rufozonatus complex from imperiled Song Giang River valley Khan Hoa Province, Southern Vietnam. Although truongi sp. nov. and anakradaya are syntopic, they not particularly closely related can be differentiated each other all on basis meristics, morphometrics, color pattern, ...

In spite of the potential richness in biodiversity, Manipur is still one least explored areas northeastern India. this work, we report on our finding four pit viper species, namely, Trimeresurus mayaae, T. salazar, erythrurus, and Protobothrops jerdonii during herpetological surveys 2022. We affirm identity these specimens based combination standard morphological characters mitochondrial cytoch...
