Abstract

Reticulated python (Malayopython reticulatus) is a widely distributed snake covering throughout Southeast Asia and almost all of Indonesia archipelago and divided into several subspecies based on morphological variation and its locality. Morphological variation data of M. reticulatus from Indonesia population has never been done thoroughly. This study aims to determine the morphological variations based on 21 meristic and 3 morphometric characters from several populations in Indonesia. The data was collected from the Museum Zoologicum Bogoriense (MZB) Cibinong, Indonesia and other additional collections that are carried out from June to July 2018 and then analyzed by Principal Component Analysis (PCA) to determine the population grouping. The result showed a high variation on the scale range of anterior prefrontal, posterior prefrontal, frontal, parietal, preocular, postocular, loreal, temporal, upper labial, lower labial, and dorsal scales. Ventral and subcaudal scales in male and female specimens show high variation in the total scale count, the ratio comparison of tl: SVL measurement, indicated the sexual dimorphism. Prefrontal (anterior-posterior) and frontal scales show high variation and difficult to distinguish between each locality at the subspecies level and suggest it to be intra-specific variation. There is no significant grouping were found between populations from data on morphological variations.

Abstract

Amfibi (Ordo Anura) merupakan bagian dari komponen ekosistem yang memiliki peranan sangat penting. Penelitian ini bertujuan untuk menganalisis struktur komunitas Ordo Anura di Lokasi Wisata Bedengan daerah Kabupaten Malang. Metode yang digunakan adalah Visual Encounter Survey (VES) yang dikombinasikan dengan purposive sampling melalui  jalur akuatik yang dibagi menjadi 2 zona yaitu 300×5 meter di bagian atas jembatan dan 300×5 meter di bagian bawah jembatan. Penelitian dilakukan sebelum musim penghujan, penghujan awal, dan penghujan, pada bulan Oktober-Desember 2018. Data yang diperoleh dianalisis dengan menggunakan indeks keanekaragaman Shannon-Wiener, kepadatan dan kepadatan relatif. Hasil penelitian menunjukkan bahwaempat famili yang berhasil diidentifikasi yang meliputi Famili Ranidae, Bufonidae, Microhylidae, dan Megophrydae.  Perhitungan indeks keanekaragaman di Bedengan menunjukkan nilai yang rendah yakni sebesar 0,96. Kepadatan dan kepadatan relatif mengalami kenaikan dimulai dari sebelum penghujan, penghujan awal dan pada saat musim penghujan, akan tetapi keanekaragaman mengalami fluktuasi.

Abstract

The purpose of this study was to determine the structure and condition of seagrass communities  in the waters of hadirin Beach and Batu lawang karimunjawa. national park. This exploratory research used descriptive qualitative methods, each study location is divided into two transects. Data identified at SPTN Office 1 Kemujan Karimunjawa National Park. The results of the study were six species of seagrass, namely: Holodule uninervise, Thalassodendron ciliatum, Halophila minor, Syringodium isoetifolium, Thalassia hemprichii and Cymodocea serrulata. The percentage of seagrass cover namely Holodule uninervise is 38.04 %. Thalassodendron ciliatum of 6.25%, Halophila minor of 29.56%, Syringodium isoetifolium of 31.25%, Thalassia hemprichii at 14.21% and Cymodocea serrulata to 16.9%. The highest density of seagrass species in Hadirin Beach is from the Uninervise holodule species 72.30%, with 858 stands on the first transect and 54.66% on the second transect with 253 stands. Whereas for the highest Batu Lawang Beach is the species of Thalassia hemprichii 51.1% with 162 stands, on the first transect and 44.9% with 114 stands. The substrate has the type of sandy clay and coral fragments. Holodule uninervise is the most dominant species found on the beach of Hadirin meanwhile Thalassia hemprichi is the most dominant species in Batu Lawang.
