Abstract

Species diversify through speciation and accumulate in ecological community, a process known as community assembly. Relying on both evolutionary mechanisms acting at regional scale and ecological mechanisms acting at local scale, the process of community assembly results from intricate interactions among mechanisms at play across varying spatial and temporal scales. During the last decade, community assembly theory has been reconsidered in the light of evolutionary dynamics of species diversification and ecological dynamics have been formalized in an explicit spatial framework (i.e. metacommunity theory). The aims of the present review are: (1) to present the community assembly theory and the main paradigms that have been proposed, (2) to discuss how the metacommunity theory as defined an explicit spatial framework for community ecology, (3)to discuss the potential mechanisms at play during community assembly and their associated predictions, (4) to present new approaches to study community assembly based on phylogenetics approaches and discuss how they have been integrated in empirical studies.

Abstract

Studi mengenai penangkapan udang air tawar dengan metode eksperimental fishing telah dilakukan di Danau Kampus Institut Pertanian Bogor. Penelitian ini bertujuan untuk mengetahui efektivitas penangkapan udang air tawar dengan menggunakan alat tangkap Tray net dan bubu yang diberi tiga jenis umpan yang berbeda, yaitu terasi, pelet pakan ikan dan kelapa bakar. Alat tangkap tray net lebih efektif dibandingkan bubu dalam penangkapan udang, namun umpan terasi yang dimasukkan kedalam perangkap bubu adalah umpan yang paling efektif diantara ketiga jenis umpan yang diberikan. Udang air tawar yang diperoleh diidentifikasi dan didapatkan dua jenis udang yaitu Macrobrachium lanchesteri dan Caridina propinqua sebanyak 474 individu.

Abstract

Provinsi Jambi memiliki hutan hujan tropis dataran rendah yang mengalami deforestasi tercepat  di daerah Asia. Efek dari perubahan alih  fungsi hutan ke habitat pertanian akan mengubah kondisi ekosistem. Hal tersebut diduga berpengaruh pada keanekaragaman  makroinvertebrata di  dalamnya.  Kesalahan identifikasi morfologi dapat disebabkan oleh fenomena cryptic species maupun siblings species. Fenomena tersebut dapat menyebabkan masalah sinonim yaitu terdapat nama ganda pada satu spesies yang sama. Untuk menyelesaikan permasalahan tersebut dapat digunakan teknik DNA Barkode. Penelitian ini bertujuan untuk mengidentifikasi dan memastikan spesies udang air tawar yang berasal  dari  provinsi  Jambi  dengan  mengaplikasikan  teknik  DNA  barcoding.Berdasarkan identifikasi morfologi didapatkan 3 sampel terdiri dari satu famili. Berdasarkan analisis COI gene, 2 spesies berhasil diidentifikasi yaitu Macrobrachium malayanum dan M. pilimanus. Satu spesies sampel target yaitu M. malayanum 1 terbukti sebagai spesies M. malayanum yang sesuai dengan data GenBank.

Abstract

ABSTRACTThis study aimed to quantify the population of Birgus latro in the Batudaka di Togean islands, Central Sulawesi. The research on robber crab was conducted in Batudaka Island, Togean, Tomini Bay, Central Sulawesi. In the study site, 21 plots measuring of 50x50 m2 were created bounded by raffia. Feed in the form of shredded coconut is placed in each plot in the afternoon. At night was performed observations and catchs. In the "base camp" every crab crab carapace caught measured in carapace length and weight. During the study, 277 crabs were caught, consisted of 173 males (62.45%) and 104 (37.55%) females. Based on the formula calculation of Schiller (1992) population figures obtained 821 803 ± 195 030 crabs in Batudaka Island. By regression analysis between carapace length with weight, it was found that the growth of B. latro is negative allometric, i.e., weight gain is faster than the increase length of carapace. The weight gain of female is slightly higher than that of the male. Whether male crab population or female equally composed of 9 age groups. This study showed that 66.7% of male crab and 29.1% of female crab has entered the market size.Keywords: Birgus, crab, carapace

Abstract

DAISY WOWOR. 1985. Population structure and spawning period of Udang Regang (Macrobrachium sintangense). BeritaBiologi 3(3): 116- 120. Population structure and spawning period of Macrobrachium sintangense was observed in a coast of a small artificial lake, Situ Ciletuh, Ci gombong, West Java, from December 1981 to August 1982. Examination of the class-size frequency indicated the growth rate of body length of the population, and its spawning periods.The mean growth rate of carapace was 3.44 mm per month.Sex ratio was 1:1, significant at the 95% level. The number of the larger males is greater than the females, which indicate the phenomenon of sexual dimorphism.This is due to the differences of growth and the maximum body size attained by the males and females. It was observed that M. sintangense spawns throughout the year, maximum spawning activity occurs between March and June.

Abstract

Salah satu problem utama dalam pemeliharaan kadang ialah pemenuhan kebutuhan akan makanan tambahan bagi pertambahan laju pertumbuhan iLing 1972, Willis et al 1976, Suharto 1977) yang efisien.Makanan tambahan tersebut dapat berupa cacahan daging, makanan kering atau bentuk-bentuk lainnya. Mulai awal September 1979 sampai dengan pettengahan November 1979 telah diadakan pengamatan terhadap laju pertumbuhan udang regang Macrobrachium sintangense (de Man) yang diakibatkan karena pemberian tiga macam makanan buatan yang dibuat dari bahan makanan yang sederhana.Udang tersebut adalah udang air tawar yang umum dijumpai dan dapat dipelihara di akuarium tanpa banyak mengalami kesukaran dan perlakuan (Sabar, 1979).
