As a subset investigation to discover indigenous prokaryotic species in Korea, a total of 21 bacterial strains assigned to the class Betaproteobacteria were isolated from a wide range of environmental samples which collected from fresh water, roots of plants, mineral water and soil from ginseng farm. Phylogenetic analysis based on 16S rRNA gene sequences indicated that 21 isolated strains were most closely related to the class Betaproteobacteria, with high 16S rRNA gene sequence similarity (>99.1%) and constructed a robust phylogenetic clade with the closest species in the class Betaproteobacteria. These isolated species have no previous report or publication in Korea; therefore 17 species in 14 genera of 6 families in the order Burkholderiales, 1 species in the order Methylophilales, 2 species in 2 genera of 1 family in the order Neisseriales are reported for betaproteobacterial species found in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are also described in the species description section and as an image.

An outcome of the study to discover indigenous prokaryotic species in Korea, a total of 26 bacterial species assigned to the classes Bacteroidetes and Firmicutes were isolated from diverse environmental samples collected from soil, tidal flat, freshwater, seawater, wetland, plant roots, and fermented foods. From the high 16S rRNA gene sequence similarity (>99.0%) and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to each independent and predefined bacterial species. There is no official report that these 26 species have been described in Korea; therefore 14 strains for the order Flavobacteriales and two strains for the order Cytophagales were assigned to the class Bacteroidetes, and 8 strains for the order Bacillales and 4 strains for the order Lactobacillales were assigned to the class Firmicutes are reported for new bacterial species found in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are also described in the species description section.

During the course of investigation of indigenous prokaryotic species in Korea, a total of 30 bacterial strains belonging to the phylum Firmicutes were isolated from diverse environmental sites such as soil, avian feces, wastewater treatment plants, fermented vegetables, seawater, algae, sea cucumber, octopus and tidal flat sediment. Phylogenetic analysis based on 16S rRNA gene sequences revealed that each strain showed high sequence similarity (${\geq}98.7%$) to the closest type strain and formed a robust phylogenetic clade with the most closely related species in the phylum Firmicutes. To date, there is no official record of these 30 species in Korea. Therefore, we report 26 species of 12 genera in the order Bacillales and 4 species of 4 genera in the order Lactobacillales which have not been reported in Korea. Morphological and biochemical characteristics, isolation sources and NIBR deposit numbers are described in the species descriptions.

Two newly recorded carnivorous amphipod species, Anonyx gurjanovai Steele, 1986 and A. nugax (Phipps, 1774) belonging to the family Uristidae Hurley, 1963, were collected from the East Sea, Korea. Anonyx gurjanovai is included in the A. laticoxae group and is characterized by a concave palm of the propodus in gnathopod 1 and small posteroventral projection at epimeron 3. The other species, A. nugax, represents the A. nugax group and is distinguished from congeneric species based on the presence of a shorter and less acute projection on epimeron 3. There are 13 species of the A. nugax group recorded worldwide, but this is the first report on the presence of the A. nugax group in Korean waters. Previously, three species of the genus Anonyx had been reported in Korea, and through this study, we have added two newly recorded species. Both the newly recorded Anonyx species are illustrated and compared with the related species. A key to the Anonyx species in Korea is also provided.

Aecial host ranges of four Gymnosporangium species causing cedar-apple rust diseases, G. asiaticum, G. cornutum, 5. japonicum and G. yamadae, were investigated through artificial inoculation. Thirteen species of nine genera among Rosaceous plants, which have been reported as social hosts in Korea, were inoculated with fresh teliospores spores in early days of May of 2000 and of 2001, respectively. In the results, we re-confirmed that there was highly specific relationship between the rust species and aecial hosts and report new aecial hosts of four Gymnosporangium species. Teliospores of G. cornutum collected from Juniperus rigida successively produced spermogonia and aecia only on Sorbus alntifolia, the first report on host alteration of G. cornutum in Korea. Positive responses by teliospores of G. japonicum from J. chinenis of Suwon and from J. chinenis var. horizontalis of Jeju island were obtained only on P. villosa. Crataegus pinnatifida was confirmed as a new aecial host of G. viatium. Until this time, G. ymadae was believed to have Malus as the aecial host. However, teliospores of G. yamadae collected from J. chinensis var. kaizuka successively formed spermogonia and aecia on the leaves of Chaenomeles lagenaria, C. sinensis, Pyrus pyrtifolia var, culta, P. ussuriensis, Malus pumila and M. sileboldii. The date for maturation of spermogonia and aecia, and symptom development varied according to the rust fungi and aecial host plants, respectively.

Robinia pseudoacacia is one of most widely cultivated exotic species in Bulgaria. The total area of black locust plantations amounts to 2.9% of the total forest area of the country. 15.34% of the plantations are of management afforestations category, where the priority is given to timber production. They have been created on rich and moisture soils, which are the most appropriate for the species in order to achieve its biological potentials of high productivity. The rest of the available plantations in the country are planted on poorer and drier soils up to 600~800 m altitude. The high adaptive ability of the species to unsuitable environmental conditions as well as the high sprout potential was used for their creation. These stands are mainly done with the aim to protect and ameliorate damaged environments and production of small-size timber and fire woods. They are cultivated until 15-20 years and are revived by sprouts. Therefore the management goals searched, 45.69% of those forests are low productive and 38.97% with average productiveness. The present report deals with growth and productivity capacity of black locust plantations; production of sowing materials; production of reproductive and vegetative saplings for afforestation; the technological aspects of afforestation works; the management and use of black locust plantations as well as some more important diseases and pests affecting the species. The report is entirely based on Bulgarian scientific research works and experience with the Robinia preudoacacia. Recommendations for optimizing the use of species are given.

A taxonomic study was recently carried out on species of the tribe Ceramieae (Ceramiaceae, Rhodophyta), following an evaluation of previously published records and on the basis of field and laboratory investigations. In Morocco, the tribe is represented by 5 genera: Ceramium (21 taxa at specific and infraspecific levels), Gayliella (3 species), and by one species each of Centroceras, Corallophila and Microcladia. Among these, there are five new records for Morocco: Centroceras gasparrinii, Ceramium botryocarpum, Ceramium cingulatum, Ceramium echionotum var. mediterraneum, and Gayliella taylorii. The report of C. echionotum var. mediterraneum from the Atlantic coast of Morocco is one of the rare records from outside the Mediterranean. Ceramium ciliatum var. robustum and Ceramium codii are recorded for the first time from the Atlantic coast of Morocco. Centroceras clavulatum is excluded from Moroccan flora having been misidentified for C. gasparrinii. This paper summarizes the taxonomic characters of these species with images and presents a key for their identification. This report is the first detailed record of the species of the tribe Ceramieae for Morocco. As a result, the total number of taxa at both specific and infraspecific levels accepted in the tribe Ceramieae for Morocco, under current taxonomy and nomenclature, is 27.
