TLDR
A plankton sample from Lake Devikulam, a temperate, high-altitude lake in the Western Ghat range, Kerala state, Southern India contained 24 rotifer species.Abstract:
A plankton sample from Lake Devikulam, a temperate, high-altitude lake in the Western Ghat range, Kerala state, Southern India contained 24 rotifer species. Its interest lies in the fact that, beside widespread eurythermic, warm-water and one Paleotropical species, one or two new, possibly endemic species were found. The geographic and climatologic isolation of the temperate habitats of the Western Ghats may account for this peculiar taxocoenosis. Polyarthra indica sp. n. is described. The trophi morphology of three Polyarthra species is documented using scanning electron microscopy and its relevance to the taxonomy of Polyarthra discussed.read more

Species Diversity of Planktonic and Epiphytic Rotifers in the Backwaters of the Delhi Segment of the Yamuna River, with Remarks on New Records from India
Jyoti Arora,Naresh K. Mehra +1 more
TL;DR: The backwaters of the Delhi segment of the Yamuna River are shallow, weedy, and perennially open lentic habitats that harbor a rich variety of zooplankton, particularly rotifers, which consist mainly of cosmopolitan and tropicopolitan taxa.

On the evolution and morphology of the rotiferan trophi, with a cladistic analysis of Rotifera
TL;DR: The phylogeny of Rotifera was examined in different computer-generated cladistic analyses, including Seisonidea, BdelloideA, Flosculariacea, Collothecacea and all ploimids treated on family level, and suggested that the presence of an incus is synapomorphic for Gnathifera while mallei are synapomorph for Micrognathozoa andRotifera.

TL;DR: The highest species richness was recorded in old, shallow, fish-free softwater lakes at high altitude, andSalinization and uncontrolled introduction of alien fish species may lead to reduced species richness in these remote freshwater ecosystems.

Cryptic diversity within the rotifer Polyarthra dolichoptera along an altitudinal gradient
TL;DR: It is shown that P. dolichoptera is a complex of species which distribution is driven by geography and environmental parameters whose importance is different in low- and high-altitude lakes, which points to a major contribution of other variables, potentially in-lake properties such as competition, predation and species behaviour.

Latitudinal variation in associations of planktonic Rotifera
TL;DR: The planktonic Rotifera are not all cosmopolitan in their geographical distribution, but there is evidence of a small group of species restricted to the Americas and this variation can be attributed to species in nine genera.
