Penelitian keanekaragaman dan distribusi benih ikan di beberapa tipe habitat Sungai Batanghari, Jambi telah dilakukan dengan tujuan untuk mengetahui keanekaragaman benih ikan, habitat, dan distribusi. Penelitian ini dilakukan di perairan daerah aliran Sungai Batanghari yang terletak di Kodya Jambi (Danau Teluk dan Danau Buluran Kenali) dan Kabupaten Batanghari (Danau Kaos, Sungai Terap, Sungai Lubuk Ruso, dan Sungai Pijoan). Penelitian dilakukan pada waktu air surut setelah banjir besar. Contoh benih ikan dikumpulkan dari hasil percobaan penangkapan dan tangkapan nelayan kemudian diidentifikasi. Larva yang belum dapat diidentifikasi dipelihara terlebih dahulu di dalamhapa, danau, dan akuarium. Hasil penelitian menunjukkan bahwa terdapat 90 jenis benih ikan yang termasuk ke dalam 44 genus, 18 famili, 5 sub ordo dari Ordo Perciformes (Percoidei, Gobioidei, Anabantoidei, Channoidei, dan Mastacembeloidei) dan 6 ordo (Osteoglosiformes, Cypriniformes, Siluriformes, Perciformes Cyprinodontiformes, dan Tetraodontiformes). Famili Cyprinidae mendominasi jenis yang ditemukan yaitu 40 jenis, diikuti oleh Famili Bagridae 15 jenis. Padawaktu air banjir kualitas air di lokasi penelitian menunjukkan kondisi yang baik untuk kehidupan benih ikan dan pada saat air surut setelah banjir kualitas air menurun. Habitat benih ikan di lokasi pengamatanmerupakan habitat sementara dan setelah kualitas airmenurun benih-benih ikan melakukan ruaya menuju ke sungai utama dan seterusnya beruaya ke bagian hulu sungai. Study on biodiversity and distribution of fish fry in some type of habitats of Batanghari River basin, Jambi was conducted to observe the kind of fish species, habitat, and the distribution. Location of the experiment were Batanghari River in Kodya Jambi (Teluk Lake and Buluran Kenali Lake and Kabupaten Batanghari (Terap River, Lubuk Ruso River, and Pijoan River).The study used survey method for every lowest fluktuation water. Larva and seeds fish were collected from fishermen and identified. For larvae were collected and held in aquaria or in hapas in lake before identified. The results show that 90 species seed fish were collected, there are 44 genus, 18 familiy, 5 sub ordo from Ordo Perciformes (Percoidei, Gobioidei, Anabantoidei, Channoidei, dan Mastacembeloidei) and 6 Ordo (Osteoglosiformes, Cypriniformes, Siluriformes, Perciformes Cyprinodontiformes, dan Tetraodontiformes), about 40 species dominated by Cyprinidae. Water quality in location was good for hight water fluctuation and bad for lowest water fluctuation. Four habitats of seed fish were not permanent habitat and in bad condition water quality, seed fish were migrating out of the floodplain and leaved for up stream of Batanghari River.

A study on Assamese monkeys (Macaca assamensis) in Kaligandaki river basin at Ramdi of Palpa and Syangja districts of western Nepal was performed. The field study was conducted from February 2015 to January 2016 spending 1804 hours to explore the ecology and feeding behavior of Assamese macaque. The study mainly focused the Ramdi village area. A total of 24 individuals of Assamese monkeys were counted towards Palpa district and 18 individuals were counted towards Syangja district. Crop raiding status was examined each year by questionnaire survey method for local household villagers as well as direct observation by the researcher. It was found that maize (47.14 %) was the highest raided among the crops, followed by fruits (16.43 %), wheat (11.13 %), millet (5.72 %), rice (4.58 %), potato (4.27 %), lentil (4.07 %), mustard (1.26 %), pumpkin (1.14 %), bread (0.96 %), brown lentil (0.81 %), broad beans (0.80 %), sesame (0.60 %), black pulses (0.35 %), dal (0.20 %), cauliflower (0.14 %), tomato (0.1 %), egg (0.1 %), samosa (0.1 %) and gram (0.1%).

This paper includes the presentations of development perspectives of the villages along the right bank of the Krka river that are within, or on the edge of the Krka National park and the results of empirical research of the opinions and attitudes of the local population regarding the preservation and protection of the environment in this area. Using the survey method, we examined the opinions of the adult population of Krka river basin in the rural area of Skradin hinterland. The questions focused on a number of issues regarding preservation and/or threat to the environment. The research is a part of the project "Titius: Krka river basin - heritage and socio-cultural development", which is conducted by the Department of Sociology, University of Split. The results of the survey show that great majority of respondents think that the environment in their region is entirely or mostly preserved, and in the same time more than half of respondents agrees with the statement that the soil is contaminated with artificial additives and that the agricultural products are increasingly less natural, as a result of the technologies used in farming. Also, almost three quarters of the respondents consider that the rivers and water are not polluted, and one quarter argues that the illegal dumps, especially of plastic materials and bulky waste spread everywhere, and that the cars and the local industry have polluted the air in their living area. Attitudes and opinions are discussed in relation to socio-demographic characteristics of respondents and their level of education.

A methodology has been developed and demonstrated which is capable of determining total amounts of asbestos fibers and fibrils in air ranging from as low as fractional nanograms per cubic meter (ng/m3) of air to several micrograms/m3. The method involves the collection of samples on an absolute filter and provides an unequivocal identification and quantification of the total asbestos contents including fibrils in the collected samples.The developed method depends on the trituration under controlled conditions to reduce the fibers to fibrils, separation of the asbestos fibrils from other collected air particulates (beneficiation), and the use of transmission microscopy for identification and quantification. Its validity has been tested by comparative analyses by neutron activation techniques. It can supply the data needed to set emissions criteria and to serve as a basis for assessing the potential hazard for asbestos pollution to the populace.
