Deforestation will affect changes in the condition of the waters of the protected and secondary forest watersheds that can affect in it biota . Fish have limited ability to choose areas that are safe for their lives, especially the environment that is very supportive for the availability of food sources. The fish population in the Dong Sandar River and Rempangi as well as the diversity of fish species in both rivers is unknown. The problem of this research is how the diversity of fish species in the Dong Sandar River and Rempangi River, Sungai Laur District, Ketapang. Research on the diversity of freshwater fish species in the Dong River between the protection of protected forests and the Rempangi River in the secondary forest of Sungai Laur Subdistrict, Ketapang District, West Kalimantan consisting of 20 stations each of which there are 10 observation stations conducted on May 1 - 21, 2018. The selection of observation stations is selected (purposive sampling) which is based on consideration of the conditions and conditions of the aquatic environment. The results of the research were 884 individuals from 50 species of 18 families with the use of scattered, pukat, seluak, bubu, temilar, sauk , and ambe exploration tools. The most types of fish obtained on the Dong Sandar River and Rempangi River consist of the Cyprinidae family (20 species), Bagridae family (7 species), Siluridae family (4 species). The diversity of fish species in the Dong Sandar River and Rempangi River in Ketapang Regency is relatively moderate (H '<3) with a diversity index (H') of 2.94, if H '<1 means low diversity, if 1 <H' <3 means moderate diversity and if H '> 3 means high species diversity. The dominant index (C) on the Dong Sandar River is 0.09 while in the Rempangi River 0.11, the range of dominant index values is 0 - 1 if the value C = 0 means that there are no types of fish dominating and if C = 1 means there are other types of fish dominating. The highest evenness index (E) is found in the Rempangi River of 0.77 and in the Dong Sandar River 0.76, it can  be seen the range of evenness of species index 0-1 if the value E = 0 means low type evenness, and if the value E = 1 means evenness is relatively evenly. The species richness index (R) of the Dong Sandar River has abundant types of fish with a value of 7.26 while in the Rempangi River only 4.40. Evenness on both rivers is 57.53%.Keyword :  Diversity, Dong Sandar River, Fish, Rempangi River

 Mount Merapi National Park (MMNP) is a natural con-servation area with the main function of preserving the diversity of plants, animals and their ecosystems. In 2010, Mount Merapi suffered a large eruption which caused damage to the forest ecosystem inside. One of the locations that suffered severe damage was at Cangkrin-gan Resort. After the eruption, the affected vegetation began to grow again. The purpose of this study is to monitor and determine the di-versity of secondary forest plants in the MMNP area. The method used was a method of path and use a point-intercept transect as the sam-pling unit. The results showed that after the eruption, the Acacia de-curens dominated at each level starting from sapling, poles and trees. Based on the results of the study showed that the eruption of Mount Merapi that occurred in 2010 resulted in a change in vegetation struc-ture in the area with the Shannon-Weiner diversity index which is still low, amounting to 1.86 for seedling, 1.32 for the sapling and 0.22 for poles. At the tree level 100% is still dominated by Acacia decurens.

The study was conducted on two type of stands one was coppice sal (Shorea robusta Gaertn. F.) stand (CSS) managed by Forest Protection Committee (FPC) along with the State Forest Department and other was coppice eucalyptus (Eucalyptus tereticornis Sm.) stand (CES) solely managed by the State Forest Department. These two stands are in the Bhagabatichak forest area under Midnapore East Forest Division, West Bengal, India. In this study Importance Value Index (IVI), biomass, species diversity index (H/), concentration of dominance(Cd), species richness index(d), beta diversity(βd), index of similarity (IS), nutrient composition and soil pH of the two stands were measured. The study reveals that the highest numbers of species were available during monsoon period in both the stands; these were 71 and 43 respectively in CSS and CES. The result also shows that the highest IVI was occupied by sal in CSS and eucalyptus in CES in all the seasons. Other major species were Clerodendrum viscosum Vent, Lantana camara L., Combretum roxburghii Spreng. Highest diversity index (H/) was in CSS during monsoon (1.983) and minimum in CES during pre-monsoon (1.274). So, the species richness index (d) was higher in CSS during monsoon (28.259) and lower in CES during pre-monsoon (12.112).Cd shows the opposite trend, it was higher in CES during pre-monsoon (0.125) and lower in CSS during monsoon (0.042). β diversity reflects the rate of species change, which was highest in CSS during post-monsoon (1.300). The similarity index (IS) between the two stands was 64.91%. The total annual above ground biomass (agb) were 87008.043 kg ha-1 yr-1 in CSS and 86309.837 kg ha-1 yr-1 in CES. Among them major contributors were sal (82357.946 kg ha-1 yr-1) in CSS and eucalyptus (84246.358 kg ha-1 yr-1) in CES. In both the stands higher amount of nutrients were available in Combretum roxburghii. In CSS available NPK were 1.272%, 0.527% and 1.867% respectively in Combretum roxburghii. In CES the values were 0.864%, 0.513% and 1.724% respectively for the same species. Soil pH of CSS were 5.53 in top soil and 5.79 in subsoil, in CES soil pH were 4.88 and 5.02 in top soil and subsoil respectively. It was observed that sal stand was better than eucalyptus stand with respect to ecology and biodiversity.

The objective of the study was to obtain data on composition and structure of the forest in the midsection of the Bukit Duabelas National Park core zone, designed to complement the existing data and  provide new information  potentials for the management of the park  core zone. The study was carried out in October-November 2012. Observations were made on plots of one hectare (100 m x 100 m), which was divided into 100 subplot, measuring 10 m x 10 m each. Enumeration  of tree species with  diameters ≥ 10 cm revealed that as many as 540 individuals were recorded, consisting of 89 species and 36 families, with a total  basal area of 30.837 m2 and  only three species of Dipterocarpaceae were registered. The forest had a low diversity as indicated by low species richness, much lower than in the  undisturbed lowland  primary forests in the Batang Gadis National Park in North Sumatra, where similarity was very low (5.9 %).  The forest in the plot was designated as the  Dacryodes rostrata- Shorea leprosula Association,  named after two species with highest importance values, thus the dominant. The structure and species composition pointed to the regenerating  forest after heavy disturbances.  The forest has been  undergoing  slow natural succession,  leading to  the formation of the forest similar to the original climax forest. Natural recovery through succession could be enhanced and assisted by means of ecological restoration, through planting of tree species characteristics of forests in Jambi, including  species of Dipterocapaceae, useful species having values to maintain the livelihood of the indigenous native tribe Suku Anak Dalam  and rare, endemic other species having  high conservation values. Tujuan studi  ini adalah  untuk memperoleh data tentang komposisi dan struktur hutan di bagian tengah zona inti Taman Nasional Bukit Duabelas. Studi   dirancang untuk melengkapi data yang telah ada dan untuk menyajikan informasi baru yang berpotensi untuk digunakan dalam pengelolaan zona inti taman nasional. Penelitian dilaksanakan pada bulan Oktober-November 2012 dalam petak seluas satu hektare (100 m x 100 m), yang dibagi menjadi 100 anak-petak dengan ukuran masing-masing 10 m x 10 m.   Pencacahan pohon dengan diameter ≥ 10 cm  menghasilkan 540 batang, yang terdiri atas 89 jenis dan 36 suku, dengan luas bidang dasar total 30.837 m2 dan hanya tercatat  tiga jenis Dipterocarpaceae. Keanekaragaman jenis hutan rendah,  seperti  ditunjukan oleh  rendahnya kekayaan jenis, jauh lebih rendah dibandingkan dengan  hutan primer yang tidak terganggu di Taman Nasional Batang Gadis di Sumatra Utara, yang mempunyai  kesamaan hanya 5,9 % dengan Taman Nasional Bukit Duabelas.  Berdasarkan dua jenis dominan dengan nilai kepentingan tinggi, komunitas pohon dalam petak dinamakan Asosiasi Dacryodes rostrata- Shorea leprosula. Struktur dan komposisi jenis menunjukan status hutan sebagai hutan yang sedang beregenerasi setelah mengalami gangguan. Hutan sedang mengalami suksesi alami yang lambat menuju ke pembentukan hutan yang serupa dengan hutan klimaks aslinya. Pemulihan alami melalui suksesi dapat dipercepat dan dibantu dengan restorasi ekologi melalui penanaman jenis-jenis khas hutan alami Jambi, termasuk  Dipterocapaceae, jenis-jenis bermanfaat dan mempunyai nilai untuk keberlanjutan kehidupan dan kesejahteraan masyarakat asli Suku Anak Dalam dan jenis-jenis langka, endemik dan jenis lain yang mempunyai nilai konservasi tinggi.

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.

AbstractPollen is the main food for honeybee broods and young workers and so colony development and reproduction rely heavily on pollen availability, both spatially and temporally, in the environment. Intensification of agriculture and climate seasonality are known to alter honeybee foraging patterns and pollen intake through changes in resource availability in temperate regions; however, little is known about how honeybees respond to such environmental factors in tropical regions.Pollen species collected by honeybees in a Neotropical agricultural region of Colombia were identified. The effects of landscape structure (landscape Shannon Diversity Index, forest area in 1000 m around the apiary) and climate seasonality (mean monthly precipitation) on the amount, richness and diversity of pollen collected by the honeybees were evaluated for all pollen species together and pollen species segregated according to forest and anthropic areas (croplands, grasslands, woodlands, urban areas).Honeybees were found to be much more associated with anthropic than forest pollen species regardless of landscape structure or precipitation. However, the amount, richness and diversity of pollen from all species and forest species responded positively to landscape diversity and forest area, suggesting an advantage for honeybees in obtaining small quantities of pollen from forest species, in spite of being well-adapted to forage in anthropic areas. Precipitation was found not to be related to the overall amount and overall richness of pollen collected by honeybees, suggesting that climate seasonality was not an important factor for pollen foraging. Nonetheless, overall pollen diversity was negatively affected by precipitation in less diverse landscapes, while anthropic pollen diversity was negatively affected in more forested landscapes. These findings are compared with those from temperate regions, and the implications for honeybee productivity and survival, and their interactions with Neotropical native species, are discussed.

Abstrak. Sub Sub DAS Cikujang merupakan salah satu bagian dari Sub DAS Cimanuk hulu yang dapat menyumbang sedimen ke waduk Jatigede yang berasal dari erosi sebagai akibat perubahan penggunaan lahan yang tidak sesuai dengan kondisi fisik lahan. Hasil kajian memperlihatkan  pola perubahan penggunaan lahan di Sub Sub DAS Cikujang periode 1994-2009, terjadi perubahan penggunaan lahan dari kawasan lindung menjadi kawasan budidaya seluas 742,20 ha. Kawasan lindung pada tahun 1994 seluas 3.213,03 ha menurun menjadi 2.470,83 ha pada tahun 2009 dan kawasan budidaya pada tahun 1994 seluas 9.532,41 ha meningkat menjadi 10.274,61 ha pada tahun 2009 dengan laju perubahan 185,55 ha/tahun. Laju penurunan luasan hutan primer mencapai 54,45 ha/tahun, dan pada tahun 2009 tidak terdapat lagi lahan dengan fungsi sebagai hutan primer. Laju penurunan luasan hutan sekunder mencapai 135,90 ha/tahun dari 2.995,25 ha pada tahun 1994 menjadi 2.451,65 ha pada tahun 2009. Pola perubahan penggunaan lahan di Sub Sub DAS Cikujang sebagian besar dipengaruhi dengan pola perubahan hutan primer dan hutan sekunder pada kawasan lindung. Sedangkan pola perubahan penggunaan lahan pada kawasan budidaya dipengaruhi pola perubahan lahan kebun campuran, tegalan/ladang, perkebunan, dan sawah Land-Use Change Pattern in Cikujang Catchment Area Abstract. Cikujang catchment area is one part of the subzone Cimanuk that can contribute sediment upstream reservoirs to Jatigede derived from erosion as a result of changes in land use that is not in accordance with the physical condition of the land. Based on analysis result of land-use change pattern in Cikujang catchment area in 1994 – 2009 period, land-use had changed 742,20ha from protected areas to cultivated areas, where protected area had decreased from 3.213,03ha in 1994 to 2.470,83ha in 2009 and cultivated area had increased from 10.274,61 ha in 1994 to10.274,61 ha in 2009 with changing rate ha/year. The rate of decreasing primary forest area was 54.45ha/year, as a result there was no land function as primary forest in 2009.  The rate of decreasing secondary forest area was 135,90ha/year ranging from 2.995,25ha in 1994 to 2.451,65ha in 2009. Land-use change pattern in Cikujang catchment area dominantly was influenced by changing pattern of protected forest and secondary forest in protected area, but in cultivated area land-use change pattern was influenced by changing pattern of farm, grassland, and rice field.

A study on Echinoderms community structure in marine national parks of Wakatobi, Southeast Sulawesi was conducted in six locations, i.e., Waha Beach, Coastal Sombo, Beach Houses, Beach Kapota, Banakawa beach, and Umala beach in October 2013. All of the six parks were located the Wakatobi territorial waters with coordinates of 5°06'25" S and 123°124'10 E. The results showed of 18 species of echinoderms representing six different types of Asteroidea, two types of Ophiuroidea, six types of Echinoidea, and four types of Holothuroidea. Group of starfish or Asteroidea was the most prominent on seagrass area. Based on the six transects sites, it turned out that the group of starfish (Asteridea) occupied a relatively high level of species richness. From the quantitative analysis values, we obtained diversity index (H) of 1.105 in Sombu, the highest evenness index (J) of 0.989 was found in Umala, and the highest species richness index values (D) of 0.132 was obtained in kapota. It seemed that all echinoderm groups were generally like seagrass microhabitat (12 types). While, sand and dead coral habitats were only occupied by 8 (eight) echinoderm groups.
