The goal was to include new accessions of perennial leguminous and cereal grasses to the collection, to evaluate them in terms of a set of valuable morphological and economic features and to identify sources of these features for breeding.Results and discussion. The collections of gene pool accessions created due to introduction of cultivars and wild forms as well as breeding accessions identified during practical breeding serve as initial material for the breeding of red clover, alsike clover and cock's-foot in the Institute of Agriculture of the Carpathian Region. For the period of 2000-2017, 944 accessions of forage grasses registered in the Central Database were included in the collection: 405 legumes (red clover – 161, alsike clover – 11) and 539 cereals (cock's-foot – 145); 591 accessions were stored in the National Depository. In-depth studies of morphological and economic traits of the accessions allowed us to create and to register a basic collection of the forage grasses gene pool, a trait collection of red clover for yield and resistance to powdery mildew (it includes 52 accessions from 5 countries), a trait collection of cock's-foot for yield and resistance to unfavorable factors (49 accessions from 8 countries) and to register valuable red clover accession No. 193 and cock's-foot accession Drogobychanka Piznia with the NCPGRU. Based on the collection accessions, varieties were created and included in the State Register of Plant Varieties Suitable for Dissemination in Ukraine: red clover Truskavchanka since 2016, alsike clover Prydnistrovska since 2002, cock's-foot Marichka since 2014. Since 2015, red clover variety Ukrainochka and cock's-foot variety Boikivchanka have been tested in the state scientific expert evaluation.Conclusions. The creation of the genetic resource collection allowed us to study and analyze the genetic potential of the species, to identify initial material with valuable economical traits, which will significantly increase the efficiency of fodder grasses breeding.

First Time

The state of Mato Grosso is the 3rd largest Brazilian state, is covered with three major Brazilian biomes, including the Pantanal, Cerrado, and Amazonia. To date, 449 ant species are recorded in literature for the state. In the present work, we documented the ants sampled along a fragmented landscape, in the municipality of Juara, in the Cerrado-Amazon transition zone in the state of Mato Grosso, Brazil. The ant species were captured with Pitfall traps installed in 20 trails with 10 traps in each (totaling 200). Our results show 151 species, belonging to 43 genera and eight subfamilies, of which 28 species were recorded for the first time in the state and five species recorded for the first time in Brazil. Most genera collected were Pheidole Westwood, 1839 (45 species) followed by Crematogaster Lund, 1831 (11 species). By highlighting species recorded for the first time in state of Mato Grosso and Brazil, we hope to encourage new discoveries and increase the general knowledge of the ant fauna of different biomes in the region.

Behuria mestrealvarensis (Melastomataceae) from the state of Espírito Santo, Brazil, is described, illustrated and compared with B. capixaba, the species most similar to it. Behuria mestrealvarensis differs from B. capixaba by the glabrous petioles and hypanthia, by the solitary flowers or these in simple or compound triads up to 7 flowers, elliptic bracteoles almost the same size of the pedicel and hypanthium, sepals with eciliate margins and ovary apex with trichomes up to 0.5 mm. It occurs in a single locality, on an isolated, ca. 800m elev. inselberg. Due to its restricted occupancy area, fragmented landscape and poor habitat quality, this species must be considered as Critically Endangered according to IUCN criteria.

Reclamation System

The features of the survey, design and operation of irrigation and drainage systems in the area of the international airport «Zhukovsky» located in the Moscow region, Russia. Design surveys included an ornithological survey of the reclaimed area. Bird species, nesting sites and the number of nests were identified. The number of nests before reclamation averaged 200 ± 1.5 (mean ± standard error). Hydro reclamation in the airport area eliminated local swamping areas and nesting areas disappeared. Draining was carried out by open drains. The distance between the open drains is 120 m, the length is from 700 to 1200 m. There are no capital irrigation and drainage facilities. On the polder site the project provides for open drains and drains. The state of the land reclamation system has been deteriorating since 2001. Periodic waterlogging of a part of the polder area and the formation of a nesting area for black-headed gulls are noted. Airbus A321 aircraft fl y over the chicks while feeding at an altitude of 231.5 m, the size of which in the eyes of the chicks is comparable to the size of the parent gulls.
