Abstract

Polyploidy is a common phenomenon in plants, especially on the species of ferns. The objectives of thisresearch are to find out the variation of the ploidy levels, to know the effects on the stomata index and size ofstomata and spore in Adiantum raddianum. The materials used to conduct this observation of chromosomes numberwere made from root tips or young leaf tips (croziers). The modified squash method was used in microscopicpreparation. The result of the observation showed that there was a variation in ploidy levels from 2n = 2x (diploid) to2n = 7x (septaploid). It appeared to be general trend that the higher level the ploidy causes the lower the indexstomata but the bigger the stomata and the spore size.

Abstract

Forest alteration into agroecosystem affect many organisms including bryofauna which their survivorship depend much on their host. Coffee and tea plantation are common agroecosystem in Indonesia. So far, the effect of habitat alteration on Bryofauna community have not been known yet. The objective of this study is to determine community structure attributes i.e., abundance, diversity and composition of bryofauna living in coffee and tea vegetation. The study was located in Ungaran Mountain, District of Semarang Indonesia. Bryofauna were extracted from moss using Tullgren funnel method and were identified until possible taxa. Bryofauna sampling was conducted both in coffee and tea vegetation. Bryofauna were extracted from the moss using Tullgren funnel method. The result shows that Acari was the most abundant both in coffee and tea area. Generally, bryofauna was more abundant in the coffee vegetation than in the tea vegetation. The diversity of bryofauna was not affected neither by altitude nor vegetation. However, the diversity of bryofauna seems affected more by their host, bryophyte. Keywords: Bryofauna, Acari, coffee and tea vegetation.

Abstract

Bryofauna is the animal which live in mosses, including microarthtropod. Bryofauna microarthtropod is quite diverse but study about this fauna is rarely done, especially in Indonesia. Bryofauna has unique and specific niche, because it depends on the existence of mosses. The objective of this research is to compare the community structure of bryofauna microarthropod in three different altitude in montane zone, including: bryofauna diversity, abundance, richness and dominance. This research was conducted from April to December 2013. Sampling was conducted at three stations in different altitude, i.e. 1335 m asl, 1660 m asl and 2040 m asl. Sampling was done in purposive way, that means sampling was done only in location contained with mosses. Sampling used quadrat method, with size 1x1m, then the moss samples was taken on quadrat with size 10x10 cm in the 1x1 m quadrat. All samples was extracted using Tullgren Funnel. Bryofauna were identified in Ecology and Biosytematic Laboratorium, UNDIP dan Entomology Laboratorium Zoology Unit, LIPI. Bryofauna Microarthropod that found in montane zone were 7 class, 19 ordo, 44 sub-ordo/family. The dominants taxa on the montane zone are Oribatida and Mesostigmata. The highest bryofauna abundance were found in altitude of 2040 m asl. The highest bryofauna diversity and richnees was found in altitude of 1335 m asl. The highest bryofauna eveness were found in altitude of 1660 m asl. Bryofauna diversity is significantly different on each station. Differences in bryofauna microarthropod community strcuture were influenced by the presence of mosses at each altitude. Keywords : Community structure, bryofauna, microarthropod, montane zone

Abstract

Mango is a fruit that is very popular with the community, especially in Semarang. The taste is sweet, refreshing and has a high vitamine content is the reason this fruit has become one of the superior fruit. In the Semarang area there are quite a lot of mango trees with various varieties. These various mango varieties are potential genetic resources that need to be preserved. This study aims to explore the various mango tree varieats that grow in the municipal area of Semarang. Research techniques by exploring in 3 districts are Banyumanik, Tembalang  and Gunung Pati. The results showed 14 varieties of mango and the most widely grown varieties by the people in the municipality of Semarang are arum manis and manalagi mango. Some of them are local mangoes, mango cultivation and imported mangoes. Local varieties of mango are only found in very small quantities and have begun to scarce, so it is feared that the supply of mango germplasm is increasingly depleting. Germplasm of local mango plants is important to be preserved as a wealth of genetic resources in the Municipality of Semarang.
