Broad Concept

The current generally accepted concept of Russula maculata defines the species by yellow-brownish spots on the basidiomata, an acrid taste, a yellow spore print and a red pileus. This concept was tested using collections originating from various geographical areas mainly in Europe. Analyses of the ITS region suggested that there were three species within this broad concept. One of them, R. maculata, was identified based on the sequence from the epitype. Two other species, R. nympharum and R. sp., are described here as newly identified species. The European species R. maculata and R. nympharum grow in deciduous forests, are similar in their field aspect and are distinctly different in micro-morphological characteristics of spores, pleurocystidia and pileipellis. An Asian species, R. sp., is associated with pine and has smaller basidiomata and spores. These three species form the R. maculata complex and represent the sister clade to the R. globispora complex. This clade consists of species also characterized by a yellow-brownish context discolouration but with a different type of spore ornamentation. All of the other tested species had an acrid taste and yellow spore print but did not have a conspicuous yellow-brownish context discolouration and were placed in various unrelated clades.

The taxonomic and ecological composition of the autochthonous land mollusc fauna in different parts of the plain Ukraine was analyzed on the basis of the personal data, collection materials of the State Museum of Natural History of the NAS of Ukraine in Lviv as well as numerous literature sources. Excluding representatives of the genus Helicopsis, the taxonomy and species composition of which in the territory of Ukraine still require clarification, and the steppe part of the Crimean peninsula, in four landscape zones of Ukraine, currently, a total of 109 species of land molluscs, which are autochthonous for at least part of the analyzed territory, are registered. The maximum species diversity (103 species and 2 representatives of the genus Helicopsis) is recorded in the zone of deciduous forests, followed by the right-bank part of the forest-steppe zone. The smallest number of the autochthonous species of land molluscs was noted for the right-bank part of the steppe zone. Within the Ukrainian Polesie and the forest-steppe zone of Ukraine, the taxonomic diversity of land molluscs decreases from west to east. The number of the registered autochthonous species decreases, respectively, by 1.5 and 1.7 times, and the generic diversity by 1.3 and 1.5 times. In the steppe zone, the main centre of the species diversity is the Donetsk Upland, located in the east of the country. In taxonomic and ecological composition, land mollusc complexes of the right-bank part of the forest-steppe zone are closer to the zone of deciduous forests, in its left-bank part – to the left-bank steppe. In general, the spatial differentiation of land mollusc fauna in the plain territories of Ukraine is more strongly associated not with the boundaries of landscaped zones, but with the location of these territories with respect to the Dnieper bed and with some uplands, where the species diversity of land molluscs of the zone of deciduous forests and forest-steppe zone (Podolian Upland) and the steppe zone (Donetsk Upland) is concentrated.

Tree species diversity, distribution and population structure of tropical forests of Bharnawapara wildlife sanctuary was investigated. The study analyzed the structure of a tropical dry deciduous forest in Chhatisgarh at different sites i.e. closed natural forest, open natural forest and plantation forests of teak. The study was conducted by laying 30 quadrats, each 10 m × 10 m in size at different sites. In total, 246 trees belonging to 28 species of 17 families were recorded from 0.3 ha sampling area. Density ranged between 520 to 990 trees ha-1 subsequently, basal area ranged between 21.50 to 47.30 m2 ha-1. The dominant tree species was Cleistanthus collinus with an importance value index (IVI) of 57.70. Other important species were Terminalia tometosa (IVI 47.10), Lagerstroemia parviflora (36.92), Diospyros melanoxylon (28.42) and Madhuca indica(26.03). The Shannon-Wiener index (H′) ranged between 0.19 to 3.35 and Simpson’s index (C) between 0.12 to 0.95 indicating high tree species diversity of tropical dry deciduous forests. It is evident from the study that natural forest has an edge over plantation forest in terms of species diversity, dominance and richness. Tree species diversity, distribution and population structure provide baseline information for conservation and management of tropical dry deciduous forests in India. Efforts are needed to conserve the natural forest for their diversity and existence. They can also be supplemented with plantation forests to lower the biotic pressure.
