Rotifera assemblages of small floodplain wetlands (dobas or dubies) of lower and upper regions of the Brahmaputra river basin of Assam state of northeast India (NEI) reveal 157 species, belonging to 34 genera and 18 families, and highlight notable speciose constellation of up to 50 species/sample. One species, each is new to the Oriental region and Assam, and species of global and regional biogeographic interest form notable fractions. The biodiverse rotifer fauna and various interesting species are hypothesized to habitat diversity of the sampled dobas or dubies, impact of `the Assam-gateway’- an important biogeographic corridor of India, and location of the study area in the Indo-Burmese biodiversity hot-spot. Lecanidae and Lepadellidae are species-rich families, both of lower and upper Assam wetlands; upper Assam wetlands, in particular, are characterized by a distinct paucity of the Brachionidae and Brachionus spp., the relative paucity of Trichocerca, Keratella and Mytilina species, rare occurrence of Asplanchna and Filinia species, and lack of species of Conochilidae and Hexarthridae. Our results indicate the littoral-periphytic nature and tropical character of the rotifers. Overall, this study is an important contribution to Rotifera biodiversity of small lentic habitats of India, Asia and that of the tropics and subtropics.

This thesis deals with the hybrid warfare phenomenon and its development after 2014. It was then that the Russian Federation violated the principles of the international community and, through its actions, contributed to destabilization of Ukraine. Russian-Ukrainian conflict is mostly described as a hybrid war, although there is still no generally accepted consensus on its definition. Part of this one-case study is devoted to presenting an academic debate on this phenomenon which is then used to analyze the war in eastern Ukraine. This paper examines the various means of hybrid warfare used by the Russian Federation towards its western neighbour to destabilize it politicaly, economicaly, security-wise and socially in order to confirm that the Russian hostile activity in the Donbas region in the first phase of the conflict was hybrid warfare.
