Abstract

A study on the structure ofbird communities in three types of habitatsat Andalas University, Padang, has been carried out from November 2012 to February 2013. This study aimed to determine the structure of bird communities in those habitats. We used mist-net to catch understory birds. We succesfully caught 72 individuals which belong to24 species, 20 genera, 12 families and 3 orders, including four species of  migratory birds. The highest abundance was found in the secondary forest, and the lowest was in herbaceous dominated vegetation. The diversity indiceswere generally moderate (H’= 1,897 – 2,466)Keywords: bird community, habitat type, mist-netting

Abstract

Rimbo Panti Nature Reserve is a conservation area located in West Sumatra which consisted of two main habitat types, dry hilly and swampy forest habitat types. These forest types potentially board many species of mammals. This research was conducted from December 2015 to March 2016 in The Nature Reserve to determine the diversity of mammals occupied each type of habitats. Twenty two camera traps were installed in pairs, six pairs in the dry hilly habitat (574-871 m asl) and five pairs in the swampy habitat (216-261 m asl). From a total 109 photos, 17 species were identified, consisted of 11 species from hilly and 10 species from swampy forest habitat. There were four species found in both habitat types. Shannon-Wiener diversity index showed that mammalian diversity of Rimbo Panti Nature Reserve is moderate (H’=1.95) while mammalian diversity in swampy forest (H’= 2.06) was higher than hilly habitat forest (H’=1.54).

Abstract

The industrial liquid waste of crude palm oil contains organic material that can lead to degradation of water quality and ultimately affect the macrozoobenthos communities living on the river bed. The Masang Kecil River in Kinali Pasaman Barat receives the liquid waste of the palm oil industry. The research aimed to find out the composition and structure of macrozoobentos community in  Masang Kecil River and determine the water quality of river based on macrozoobenthic community structure was done in June 2017. The research was conducted by survey method with purposive sampling technique. Samples were collected on 3 stations: Station I before entering the liquid waste of palm oil industry, Station II after entering the waste, Station III is located after Station II which has been entered by Anak Aia stream. In each station collected three samples of macrozoobentos with a surber net size of 30x30 cm2. The results showed that macrozoobenthos community found 43 species consist of 33 species of Insecta, Oligochaeta 4 species, Gastropoda 3 species, Hirudinae 2 species, Arachnida and Turbellaria one species respectively. The largest number of individuals was shown by Insecta (71.89%) followed by Hirudinea (25.1%) and the other class was not more than 3%. The highest density is found at station III and the lowest at station I. The dominant species on station I were Stenelmis sp. and Psephenoides sp., stations II and III were Erphobdella sp. and Hydropsyche elisoma. The diversity index ranges from 1.49 to 3.01. The index of equitability ranges from 0.47 to 0.89, the dominant index ranges from 0.06 to 0.43. The similarity of communities between station ranged from 38.46 - 55.0%. Based on the index of diversity, water quality in Station I was classified as not polluted, Station II and III classified as moderate.

Abstract

Pintu Ngalau cave is flowed by river from irrigated rice fields that flows into the cave. This cave has a source of organic matter derived from bats and swallow dirts, litter that falls on enterance of the cave and the organic material carried by the flow of the river. The study on the macrozoobenthos communities of river in Pintu Ngalau Cave has been conducted from October until November 2016. The study used survey method, where stratified random sampling was applied in three zones (light zone, dim zone and dark zone) at study site. Macrozoobenthos samples was collected by surber net. This study also measured the physic-chemical of water. The results showed the composition of macrozoobenthos in the Pintu Ngalau cave river consisted of 43 genera i.e Gastropods (2 genera), Hirudinea (2 genera), Insects (36 genera) and Oligochaetas (3 genera). Total density of macrozoobenthos in this site was 2100 ind/m2 and the highest density was found in dark zone. The highest total relative density (KR total=79,89%) on genus level at every zone was Hydropsyche. Diversity index of macrozoobenthos was classified as medium (H'=2.68) with evenness distribution was evenly (E=0.61) and no dominant genus (C=0.14). The existence of macrozoobenthos was not influenced by light intensity, but instead was more influence by the condition of the substrate and the flow of water in the cave.

Abstract

Bleberan Village has ecotourism potential in terms of insects biodiversity. Moreover, this village has some beautiful tourism objects, such as Sri Gethuk waterfall and Rancang Kencono cave. In the other hand, biodiversity in this village is yet to be explored, hence this research aims at studying insects biodiversity, especially of  three orders: Orthoptera, Lepidoptera and Odonata. The final objective of this reseach is to provide information for studying and conserving biodiversity in this ecotourism region. The observation was conducted in 10 stations in both Kedung Poh (1st location) and Oyo River (2nd location ). Several ecological parameters were calculated such as density, diversity index, and distribution. In addition, enviromental parameters were also measured, i.e temperature, humidity, and light intesity. This research found 17 species of each order, with the highest number of individuals was observed in the member of Orthoptera, especially withPhlaeoba fumosa; 381 individuals (1st location 1) and  445 individuals (2nd location). In the order of Lepidoptera, species Catopsilia pomonahad the highest number of individuals, there were 31 and 46  individuals in 1st location and 2nd location, respectively. The latter is Odonata, had Orthetrum sabinawhich dominated the number with 252 individuals in 1st location and 188 individuals in 2nd location. This research also revealed that diversity index was varied between 0.79 and 0.99, with all orders were distributed in a clumped pattern. All the environmental factors had been observed and did not show any abnormality, therefore insects couldbe alive normally.
