ABSTRAK Wilayah pesisir Bedono sebagai kawasan hutan bakau yang terletak di utara Kabupaten Demak telah dikelola dan dijadikan kawasan wisata sehingga secara tidak langsung akan berdampak terhadap fungsi ekologis mangrove. Banyak organisme hidup yang berasosiasi dengan mangrove salah satunya adalah Gastropoda. Tujuan dari penelitian ini adalah mengetahui jenis Gastropoda, kelimpahan dan keanekaragaman Gastropoda serta mengetahui hubungan antara kandungan bahan organik dengan kelimpahan Gastropoda. Pengambilan sampel Gastropoda dan sedimen dengan metode kuadran transek yaitu 1 x 1m di 3 stasiun. Hasil penelitian didapatkan terdiri dari 5 genera Gastropoda yaitu Cassidula sp, Cerithidae sp, Littorina sp, Telescopium sp, dan Terebralia sp. Kelimpahan Gastropoda berkisar antara 94 – 248 ind/3m2. Nilai indeks keanekaragaman sebesar 1,08 - 1,27. Nilai indeks keseragaman sebesar 0,67 – 0,94 dan indeks dominasi sebesar 0,23 – 0,39. Berdasarkan nilai uji regresi sederhana dimana nilai koefisien korelasi berkisar 0,7 < r ≤ 1,0 menunjukkan bahwa kelimpahan gastropoda memiliki hubungan yang kuat dan memiliki korelasi dengan kandungan bahan organik dalam sedimen. ABSTRACT Bedono coastal as an area mangrove forest located at the northen Demak Regency has been managed and used as a tourism area. Many living organisms associated to mangrove, mainly Gastropods. Purpose the research a to investigate type of Gastropods, abundance and diversity of Gastropods and relationship of organic matters to Gastropods abundance. Samples of Gastropods and sediments were collected using 1x1m transect quadrant methods in 3 different stations. Results of research obtained 5 genera of Gastropods that is Cassidula sp, Cerithidae sp, Littorina sp, Telescopium sp, dan Terebralia sp. Abundance of Gastropods between 94 – 248 ind/3m2. Result of diversity index was 1,08 – 1,27. Uniformity index between 0,67 – 0,94 and domination index was 0,23 – 0,39. Based on simple regression test the value of a correlation range 0,7 < r ≤ 1,0. It was showed that gastropods abundance have a close relationship and a correlation with organic matters in sediments.

Public awareness and knowledge on mangrove forest biodiversity, especially gastropods, is very limited. This study aims to compare the density and diversity index of gastropod species according to their distance from the coastline and to analyze the relationship of the two with the physical environment around them. Three lanes were placed in the southern part of the mangrove forest. The first lane (LT-1) was placed about 5 m from the coastline towards the sea. The second lane (LT-2) was placed 10 m towards the sea from LT-1 and the third lane (LT-3) was 10 m from LT-2 towards the sea. In each lane there were 10 (1 mx 1 m) plots and the distance between adjacent plots was 10 m. A total of 1.432 Gastropod individuals consisting of 16 species and 7 families were collected from 30 plots. In detail 16 species (927 individuals) were collected from LT-1, 16 species (500 indv) from LT-2, and only 3 species or 5 individuals from LT-3. The density of LT-1, LT-2, and LT-3 species respectively was 92.7; 50.0; and 0.5 indv.m-2, while the diversity index successively was 2.56 (moderate); 2.53 (moderate); and 0.95 (low). Both species density and diversity in lanes that are close to the coastline are higher than in lanes located in the direction of the sea. The base substrate on the path that was close to the coastline was clay, while on the lane that laid in the direction of the sea was sandy loam.

A study on abundance and diversity of Hymenoptera was conducted in Gunung Datuk, Rembau. Samplings were conducted from November 2014 to February 2015 using six Malaise traps. Three traps were placed at Site 1 at 700m height for high elevation and the remaining traps were placed at Site 2 at 200m height for low elevation. A total number of 221 Hymenopteran were collected which consist of nine families namely Ichneumonidae, Formicidae, Braconidae, Bethylidae, Evaniidae, Tiphiidae, Vespidae, Pompilidae and Apidae. In this study, 93 individuals were obtained from Site 1, comprising nine families and 43 morphospecies while 127 individuals were obtained from Site 2 with nine families and 45 morphospecies. Formicidae was the most dominant family collected from both sites with a total of 104 individuals while the least family recorded was Apidae with only one individual. Shannon’s Weiner Diversity Index (H’) showed Site 1 had the higher diversity value with H’ = 3.17 compared to Site 2 with value H’ = 3.12. For Evenness Index, Site 1 had higher value compared to Site 2 with E’ = 0.84 and E’ = 0.82 respectively. Moreover, for Margalef Richness Index, Site 1 recorded R’ = 9.24 while site two recorded R’ = 9.08 which concluded that Site 1 had higher species richness compared to Site 2. Paired t-test showed that both sites had no significant difference with p>0.05. Overall study showed that the diversity and abundance of Hymenoptera in Gunung Datuk were low since the value of H’ is less than 3.50.

The following notes were assembled in arranging the Protarchoides material in the National Collection. In establishing the identity of Protarchoides mellipes (Prov.) it has been found necessary to synonymize one species. A species allied to mellipes is described as new and a table is provided for the separation of the four known North American species. The recording of Trichiosoma as host for a member of this genus is further evidence of the close relationship of the genus with Protarchus Foer.

AbstractTo study the function of the 49 kDa excretory-secretory (ES) protein gene (P49) of Trichinella, the genes was amplified by RT-PCR from RNA of Trichinella spiralis and Trichinella nativa and several Chinese Trichinella isolates of domestic animals, and sequenced after being cloned. The amplified products of these parasites produced bands of about 950 bp. The 97.2 % to 100 % nucleotides identity and 94.3 % to 100 % identity of deduced amino acids among P49 gene of these Trichinella strains showed the close relationship of these parasites. The P49 gene of T. nativa was cloned into the BamHI site of the prokaryotic expression vector pET-30a, and the recombinant vector was expressed. The expressed product was 40.8 kDa in size. In Western blot analysis, the expressed product was reactive to sera of mice infected with T. nativa, T. spiralis and their Chinese geographical strains.
