Morpho-Anatomical Analysis of Cosmostigma racemosum (Asclepiadoideae) Flowers
Full text linkCosmostigma racemosum is a plant species belonging to the family Apocynaceae, the subfamily Asclepiadoideae. Cosmostigma racemosum is found in Nglanggeran Mountain Gunungkidul, Yogyakarta. The local name and its original distribution are not known. Information or study of Cosmostigma racemosum in Indonesia is not available. Comprehensive characterization of this species is important for authentication and addition of data base. Characterization was conducted by analyzing the morphology and anatomy of flower. The objectives of this study were to describe and analyze the morphology and anatomy of C. racemosum flowers. The method of research was based on observation method and exploration of plant systematics evidence or taxonomy evidence, including analyses and description of morphology and anatomy of flower structure and its development. The results showed that the characteristics of flower morphology are in accordance with the existing description in literatures. Characteristics of pollinia are specific characters of morphological aspect of flower. Data of anatomy of flower and its parts development are the new ones which confirm the position of C.racemosum as a member of the tribe Marsdenieae. The data of anatomy also show new information of the ontogeny of the important parts of flower: pollinia formation, pollinia corpusculum, anther wall, anther sac, stigma, stamen, staminal tube, stigmatic chamber, and structure of ovary in Asclepiadoidea
Identification Of Migratory Birds And Their Spesific Characteristics Of Habitat In The Salt Water Lake Of Gili Meno, North Lombok Distric
Full text linkThe aim of this research was to identify the species of migratory birds in the ecosystem of salt water lake of Gili Meno and their specific characteristics of habitat. Data collection for birds, mangrove and fish species has been carried out in September and October 2013. In this study, a Shannon-Wiener Diversity Index and Importance Value Index (IVI) of mangrove vegetation were calculated to identify carrying capacity of mangrove population in the form of specific habitat in salt water lake of Gili Meno. This research has identified 17 species of birds which are divided into 5 families: Scolopacidae, Charadriidae, Ardeidae, Meropidae and Alcedinidae. Moreover, 3 species of mangrove were discovered that are A. marina, A. lanata and E. Agallocha, as well as one species of fish (Mujair fish/O. mossambicus). N. Nycticorax and B. Striatus were well-known to have higher population than other bird species. The Diversity Index showed that mangrove vegetation in the ecosystem of salt water lake of Gili Meno has a low species diversity (0.565). This is due to higher dominance of one species than the others. What is more, the IVI of A. marina demonstrated a fairly significant value compared to that of other species (189,01). Mangrove vegetation which surrounds the ecosystem of salt water lake of Gili Meno has formed a unique habitat and and an ideal stopover site for migratory birds. The ecosystem not only provides shelters from predators but also supplies for various abundant feeding sources. The lake it self is rather shallow and muddy around the shore which gives advantages for the migratory birds to obtain plenty small fish from the lake
