The article provides an information about floristic findings in the Maya Aldanskaya River basin. As a result of expeditionary researches, new locations of 25 species and 1 subspecies of vascular plants were revealed, including for the Aldan floristic region – 9 species: Bupleurum scorzonerifolium, Cardamine prorepens, C. macrophylla, Gentiana macrophylla, Linum komarovii, Medicago lupulina, Packera heterophylla, Triglochin maritima, Valeriana alternifolia; for the Maya River valley – 9 species and 1 subspecies: Campanula punctata, Iris laevigata, Leontopodium conglobatum, Linaria acutiloba, Lysimachia thyrsiflora, Micranthes staminosa, Polemonium boreale, Rhodiola rosea, Saxifraga cernua, Hypericum ascyron subsp. gebleri; in the Red Data Books of the Regions and the Russian Federation – 7 species: Aconogonon amgense, Alyssum obovatum, Anemone tamarae, Borodinia macrophylla, Ephedra monosperma, Hedysarum dasycarpum, Saxifraga lactea.

Special Case

Grouping both existing and newly planned reservoirs based on selected measurable characteristics allows to point out issues that are relevant to area management using experience obtained from the environment of other sites. Divisive hierarchical clustering has been deployed to find similarities between dam locations. The Nitra River Basin (located in Nitra District, Nitra Region in Slovakia) with its 54 reservoirs is the model area. Profiles for 11 potential new reservoirs have been developed. Partial river basins were identified for each of the existing and new reservoirs using a digital relief model. The area size, proportion of arable land, forestland and built-up area, degree of exposure to soil erosion and the volume of surface runoff have been used as parameters for comparisons. Six clusters have been identified containing similar existing as well as new locations, one of them being a special case.

Long Term Studies

Long-term studies of the Oka river basin have had little impact on the Eastern part of the basin, which was studied in 2019. The surroundings of a number of localities in the Ardatovsky, Vachsky, Kulebaksky, Navashinsky and Sosnovsky districts of the Nizhny Novgorod region were examined. As a result, many interesting floristic data were found. The article provides information about 25 rare species of vascular plants. New locations were identified for 9 species listed in the regional Red book, some species are located on the border of the range.

Paraná River Basin

Cnesterodon hypselurus is an endangered species from the Upper Paraná River basin, with distribution restricted to three streams with diminished habitat quality. An updated distribution including new locations in the Tibagi River basin is presented, increasing its area of occurrence and providing a new low-elevation record of 728 m. The recognition of these populations suggests that C. hypselurus might have a larger distribution in the east-central Paraná State region, changing to vulnerable the previously endangered status of the species.
