Gunung Kidul is one of the districts in Yogyakarta that has a long coastline with coral substrate and white sand. One of the beaches with coral and rocky substrates is Indrayanti Beach. The rocky substrate provides unique characteristics for the life of marine organisms in the intertidal zone. Gastropods is one of the seven classes in the Mollusc phylum. Gastropods are found mostly in the sea and fresh water, especially in the intertidal zone of beach. The aim of this study is to identify gastropods that found in the Indrayanti intertidal zone and classifying each species. The method of this study is observation and sampling techniques with accidental sampling at low tide. Data analysis is descriptive based on morphological characteristics of each species. Based on the results of this study, there are 5 sub-classes, 9 orders, 2 Superfamily, 21 families, 35 genera and 72 species. Sub-classes found are heterobranchia, caenogastropods, neritimorpha, vestigastropods, and patelogastropods. The highest number of species found in the caenogastropod subclass was 32 species (44% of the total species) which were dominated by the order of neogastropod.

The results of research on characteristic of distribution and taxa structure of Chlorophytes (Chlorophyta) at nine islands of Truong Sa archipelago (Truong Sa, Da Tay, Thuyen Chai, Toc Tan, Sinh Ton, Nam Yet, Song Tu Tay, Da Nam and Son Ca) indicate that there are 67 species of Chlorophytes, they belong to 4 orders, 14 families and 22 genera. The number of species at the sampling islands ranged from 13 species/island (Toc Tan isd.) to 43 species/island (Nam Yet isd.) with the average of 25.5 species/island. Sorensen similarity coefficient at the sampling sections ranged from 0.24 (between Song Tu Tay and Thuyen Chai) to 0.74 (between Nam Yet and Song Tu Tay) with the average of 0.45. Among 67 species in nine islands, there are 10 species distributed only in the intertidal zone (they are occupying 14.9% of total species), 14 species (31.4%) in subtidal zone only and 43 species (64.2%) in both intertidal zone and subtidal zone. The number of species concentrates on some genera (Halimeda: 10 species; Caulerpa: 10 species; Codium: 6 species,...), they belong to Codiacea, Siphonales. There are some genera with only 1 species (Tydemania, Anadyomene, Microdictyon,...).

This study investigates the deep-water flora of the continental shelf in Sergipe State, Brazil located between 10º36’08’’ – 11º21’07’’S and 36º28’10’’ – 37º13’47’’W. The samples were collected by dragging at 18 sampling sites, between 10 to 30 m depth, from May 1999 to March 2000. A total of 91 taxa of marine benthic macroalgae were identified (56 Rhodophyta, 20 Heterokontophyta and 15 Chlorophyta). Forty-seven (47) of these are new occurrences for Sergipe flora. Rhodophyta dominated, accounting for 61% of the total species collected, with the order Ceramiales having the highest number of species present (39.55%), followed by Heterokontophyta (23%), mostly represented by Dictyotales (65%). Finally, 15 Chlorophyta taxa were found (16%), mainly composed of Bryopsidales (53%).

Several factors are important determinants of students achievement. Students positive perceptions about these factors contribute to their achievement. Considering importance of students perceptions about themselves, teachers support, and institutional climate in influencing their academic achievement, this study specifically examines students perceptions about themselves as learners, teachers support, and institutional climate for predicting their achievement. This research employed survey and correlational research designs. For this research, 372 students were randomly selected as a sample using cluster and stratified random sampling techniques. For data collection in this study, a questionnaire was adapted from Donahue (1994). For data analysis, both descriptive and inferential statistics were used, with help of SPSS. It was concluded from multiple regression analysis that university students achievement (i.e., dependent variable) can be significantly predicted from their self-perceptions, teachers support and institutional climate (i.e., independent variables).

AbstractMicropsectra Kieffer, 1909 is described and diagnoses presented for the imaginal (♂♂), pupal and larval stages; females of the notescens-group are described. The genus contains at present 83 species of which 9 are described on females. The type material for 16 of these species has not been found. 142 species which have been listed under Micropsectra are presented in alphabethical order. This list contains: name of author, reference to description. name of original genus, present status of species, reference to the paper in which this was listed, collection in which the type material is deposited. Morphological characteristics, evolutionary trends and phylogenetic relationships of Micropsectra are discussed. The genera Rheotanytarsus, Parapsectra, Krenopsectra, Micropsectra and Paratanytarsus form a monophyletic group within the tribe Tanytarsini. The group is referred to as the Micropsectra series. Rheotanytarsus, the most plesiomorphic genus in the series, has a worldwide distribution. This supports the conclusions reached by the morphological analysis. The genera Parapsectra and Krenopsectra are only known from the Palaearctic and Nearctic Regions. The great majority of Micropsectra species are found in the Palaearctic and Nearctic Regions. A smaller number of species occur in the northern part of the Oriental Region, which has the same environmental conditions as the adjacent areas of the Palaearctic Region. Two doubtful species have been reported from India. Genus Paratanytarsus has a wider distribution but clearly has its origin on the northern hemisphere. The habitat selection in the Micropsectra series is studied and compared with the phylogeny. The species within the plesiomorphic genera Rheotanytarsus, Parapsectra and Krenopsectra are found in streams and springs. In the more apomorphic genus Micropsectra many of the species occur in these types of habitats, though there are also a comparatively high number of species occurring in lakes. Paratanytarsus, the most apomorphic genus contains species which inhabit shallow standing waters. It seems probable that the ancestor of the Micropsectra series was an inhabitant of running water. A lectotype is designated for Tanytarsus retusus Goetghebuer.
