Abstract

Telah dilakukan penelitian tentang “ Tingkah Laku Siang Hari Cynopterus sphinx (Vahl, 1797) pada Keadaan Hujan dan Tidak Hujan” selama enam bulan yang bertujuan untuk mengetahui bentuk-bentuk aktivitas C. sphinx pada keadaan hujan dan tidak hujan serta untuk melihat pada keadaan manakah C. sphinx lebih banyak melakukan aktivitas. Penelitian ini menggunakan metoda observasi dengan teknik Continuous Sampling selama 9000 menit kontak. Dari hasil penelitian diketahui aktivitas yang dilakukan pada siang hari oleh C. sphinx lima bentuk aktivitas pada keadaan hujan dan tujuh pada keadaan tidak hujan. C. sphinx lebih banyak melakukan aktivitas pada keadaan tidak hujan dibandingkan saat hujan, yaitu istirahat (67,44% : 65,64%), grooming (12,88% : 12,45%), agonistik (0,63% : 0,28%), seksual (0,59% : 0,00%) bersuara (0,11% : 0,00%) kecuali pindah (0,60% : 1,38%) dan bergerak (17,75 % : 20,11%).

Abstract

Melastoma L. is the type genus of Melastomataceae. While Melastoma malabathricum is the type species with the mostwide spread distribution compared to other species in this genus. This research aim to study ultrastructure morphology of Melastoma pollen. The research was carried out by collecting species which included into Melastoma genus using survey method. Ultrastructure morphology of pollen was observed with Scanning Electron Microscope Type JSM-IT-200. Pollen samples originated from the pre-anthesis Melastoma flowers. The pollen was fixated, dehydrated and coated before observed, photographed and identified with electrone microscope. One species, M. malabathricum, has prolate spheroidal pollen. Four other species, M. setigerum, M. baccarianum, M.minahasae and M. malabathricum var. malabathricum, with oblate spheroidal pollen. The scanning results from electron microscope onto these five Melastoma species observed an aperture like a gap called colpus that varied in number. Pollen ornamentation resemble striate type on these five Melastoma species.

Abstract

Abstract Diversity and potential of Megachiroptera bat as dispersal and polinator was conducted to know diversity of Megachiroptera bats at Harapan Rainforest, potential of Megachiroptera bats as dispersal seed and pollinator and to know the daily activity of Megachiroptera bats pollinate and disperse the seeds of plants in Harapan Raiforest, Jambi . We used purposive sampling method using mist net were installed 90 traps – night. The result showed that five species of Megachiroptera bat are Cynopterus brachyotis , C. horsfieldi , C. sphinx , C. titthaecheilus and Macroglossus minimus with index of diversity value and evenness index are relatively low about 0.99 and 0.62. Kinds of Megachiroptera bats potentially as dispersal are C. brachyotis , C. horsfieldi , C. sphinx , and C. titthaecheilus and bats potentially as pollinator are C. brachyotis , C. sphinx and M. minimus. The pattern of time daily activity of Megachiroptera bats as disperse seeds and pollinate plants in Harapan Rainforest by C. sphinx and C. brachyotis was whole of night with peak activity C. sphinx at night ( 21:00 pm to 00:00 am) and C. brachyotis at end of night ( 3:00-6:00 am ). Key word : Megachiroptera bat, dispersal, polinnator, Harapan Rainforest
