Abstract

The objectives of the research were : (1) to determine the distribution pattern, association, and interaction of plant species, (2) to determine the relationship between life form and the distribution pattern of species, and (3) to comparethe association chance of distribution patterns. Quadrate method was used in this project. Determination of speciesdistribution pattern was calculated using Poisson Distribution formula, and the determination of association was calculated using Contingency Table. The result indicated that: (1) The species richness were dominated by grasses, reaching 42.42%. Of the 33 observed species, 21 of them were in a clumped distribution, 7 species in a regular, and 5 species were at random pattern. (2) There are relationship between life form and the distribution of the plant species. The multi-plants tend to have a clumped distribution pattern, and single plant tend to have a regular or random distribution pattern. (3) The species of clumped distribution tend to have negative association to the species which of regular and random distribution pattern. However among the species which had the regular distribution pattern tend to have positive association. (4) The calculated results of the interaction more supported the individualistic concept of the plant association than community as an integrated unit.© 2002 Jurusan Biologi FMIPA UNS SurakartaKey words: distribution pattern, association, interaction, grassland, Baluran National Park

Abstract

Primary productivity dynamic of the water ecosystem was conducted faster in the last decades. This study was intended to find out the primary productivity of Cengklik dam Boyolali, Central Java to explain the ecosystem dynamic and to lead the maintenance of dam. This study used quantitative methods in completely randomized group design (CRD), and the data was analized by Analysis of Variance (ANAVA). Samples were taken horizontally in four sampling point, respectively in the riparian zone, around of the floating net (“karamba”), in the center of dam water and around of the ex-paddy fields. There were taken vertically in three-depth point in each of the sampling point, respectively 0.5 meter, 1.5 meter, and 2.5 meter. The results showed that the gross primary productivity of the dam was 11.122.500-22.545.600 mgC/m3/days, and the primary productivity differences in each of the point sampling caused by light intensity, nutrient supply, and abundance of the chlorophyll organisms.© 2002 Jurusan Biologi FMIPA UNS SurakartaKey words: primary productivity, Cengklik dam

Abstract

One of the biodiversity richness in Indonesia is ecosystem of Baluran National Park savanna. This type of savanna is similar to African savanna that is included in tropical savanna. There are two types of savanna, namely flat and undulating savanna. The savanna ecosystem that covers about 40% of the total area of Baluran National Park has important role on supporting herbivore animals such as wild cattle (Bos javanicus), deer (Cervus timorensis) and wild buffalo (Bubalus bubalis). The variety of grasses and other vegetation provide food for those animals, therefore, the reduction of the reduction of quality and quantity of the savanna would reduce in the population of the herbivores. The savanna in the Baluran National Park is about 10.000 ha, however, due to invasion of Acacia nilotica has resulted in the reduction of the savanna reaching about 50%. Moreover, illegal grassing inside the Park has brought negative impact to the quality of the area and the wild fauna. Overgrazing may influence on the reduction of the population of wild fauna. Pressure to the savanna has a great impact on the balance and preservation of whole ecosystem in Baluran. Efforts have been made in order to restore the Baluran ecosystem such as preventing the expansion of A. nilotica as well as preventing illegal grazing. The Baluran National Park is still looking for the most effective and efficient way of preserving savanna ecosystem in Baluran.© 2001 Jurusan Biologi FMIPA UNS SurakartaKeywords: Baluran National Park, savanna, Acacia nilotica

Abstract

The aim of the experiment was to examine whether the morphological characters of eleven species of Ranunculuscollected from a number of populations were in agreement with the genetic data (isozyme). The method used in this study was polyacrilamide gel electrophoresis using peroxides, estarase, malate dehydrogenase, and acid phosphatase enzymes. The results showed that cluster analysis based on isozyme data have given a good support to classification of eleven species based on morphological groups. This study concluded that in certain species each morphological variation was profit to be genetically based.© 2002 Jurusan Biologi FMIPA UNS SurakartaKey Words: Ranunculus, isozyme

Abstract

Plankton is components of aquatic ecosystem. Phytoplankton play as primary producers, zooplankton play an important role in the higher order in the transfer of energy primary producers, the alga, to the higher order consumers such as aquatic insects, larval fish, and some adult fish. Streams of Jobolarangan forest may show phytoplankton and zooplankton that unique. The objectives of this research were to know diversity of phytoplankton and zooplankton and to determined their density. Plankton were sampled using 25-30 μm mesh net, in three location of streams, i.e.: Parkiran (1773 m asl.), Mrutu (1875 m asl.), and Air Terjun (1600 m asl.). Samples were examined under light microscope for identification, and determined their density/L. Richness of phytoplankton in streams at Jobolarangan forest composed by family of Chlorophyceae, Euglenophyceae (Algae), and Bacillariophyceae. Zooplanktons that were found order of rotifer, cladoceras, and copepods. Allochtonous productivity, low nutrient level, low light level, and flowing water condition caused density of plankton/L in stream at Jobolarangan was low, i.e. 0,064 to 0,232.© 2001 Jurusan Biologi FMIPA UNS SurakartaKey words: plankton, Jobolarangan, richness, diversity.

Abstract

Insect larvae are macro-invertebrate that becomes the most perfect indicator of aquatic-environmental health. Natural streams usually determined by its insect-larvae community in a good condition, in which their taxonomic diversity and richness are high. The objective of the research was to know the taxonomic diversity and richness of insect-larvae family in streams at Jobolarangan forest. The larvae were sampled using net-surber (dip-net) in three location of streams, i.e.: Parkiran (1773 m asl.), Mrutu (1875 m asl.), and Air Terjun (1600 m asl.). The screened insect-larvae were grouped its family and counted their individual number. The diversity was counted using Shanon-Weiner diversity indices. In this research was found 12 families of insect-larvae consisted of two families of Odonata order, 3 families of Coleopteran order, and a family of Lepidoptera. Nine families identified, while the three insect-larvae i.e. 2 of Coleoptera and 1 of Lepidoptera were not identified yet. The Parkiran station indicated the highest diversity index of 0.1436.© 2001 Jurusan Biologi FMIPA UNS SurakartaKey words: insect-larvae, diversity, streams, Jobolarangan
