Morphology of the tracheobronchial tree of the Ganges river dolphin (Platanista gangetica).
To contribute to the phylogenetic evaluation of the river dolphin, the morphology of the tracheobronchial tree of the Ganges river dolphin was analyzed according to Nakakuki's fundamental bronchial tree model of mammals. In the right lung, the bronchial tree consists of the tracheal bronchus, five lateral series bronchi, three dorsal series bronchi and one ventral series bronchus. In the left l...
متن کاملGanges River dolphin: an overview of biology, ecology, and conservation status in India.
Ganges River dolphin, Platanista gangetica gangetica, is one of the three obligatory freshwater dolphins in the world and is distributed in the Ganges-Brahmaputra-Meghna and Sangu-Karnaphuli River systems in India, Nepal, and Bangladesh. This species is facing considerable threats to its survival, and its population has dwindled from 4000 to 5000 in the early 1980s to 3500 in 2014 in the distri...
متن کاملMorphological convergence in ‘river dolphin’ skulls
Convergent evolution can provide insights into the predictability of, and constraints on, the evolution of biodiversity. One striking example of convergence is seen in the 'river dolphins'. The four dolphin genera that make up the 'river dolphins' (Inia geoffrensis, Pontoporia blainvillei, Platanista gangetica and Lipotes vexillifer) do not represent a single monophyletic group, despite being v...
متن کاملRecognizing Meanders to Reconstruct River Dynamics of the Ganges
The long-term discharge evolution of branches of rivers can potentially be derived from inactive and fossil river meanders using relations between discharge and channel width and meander dimensions. This evolution is relevant for the understanding of river dynamics and avulsion, and the resulting changes of downstream flooding risks and shipping conveyance. Unfortunately, digitalisation of infi...
