Indonesia has at least 47 types of ecosystems, one of ecosystems that have a lot of potential in Indonesia is a mangrove forest. Mangrove forests in Indonesia have a high diversity of flora and fauna. Development and utilization of coastal areas around the mangrove forest, usually not done wisely that is likely to endanger the stability of the mangrove ecosystem in the long term. One alternative utilization of mangrove forests that could be developed without damaging the environment is the development of ecotourism. Mangrove forest in Pancer Cengkrong Karanggandu is one of the mangrove forest areas with the potential to be developed into a tourist area of mangrove. The purpose of this research is to study the potential and preferences of flora and fauna (birds) in the Cengkrong Mangrove Forest as a tourist attraction in the development ecotourism programs with community participation. Stakeholders involved in the study consisted of mangrove forest communities, students of nature lov...

Species diversity and distribution of ants has not been well investigated in Ethiopia or in Bahir Dar area, Ethiopia. The objective of this study was to identify ant taxa and determine their diversity and distribution in different terrestrial and forest habitats in Bahir Dar area. Ants were collected from the ground weekly from December 2015 to November 2016 with 10 × 13 cm baited cards in 4 traps that were 7 metres apart from each. A total of 60,000 ant specimens consisting of 5 subfamilies: Formicinae, Myrmicinae, Ponerinae, Dorylinae and Dolichoderinae and 7 genera, i.e., Lepisiota, Myrimicaria, Pheidole, Axinidris, Centromyrmex, Camponotus, Dorylus, were recorded. Myrimicinae and Formicinae were more abundant than other subfamilies. Lepisiota, Myrimicaria and Pheidole were the most abundant genera. Shannon's diversity index was higher for the roadside, built up area (residential and other buildings), grass land, cultivated area and forest in descending order. Evenness was found to be between 0.52 on cement cracks to 0.75 on roadsides and built up areas, indicating medium to high evenness, i.e., there was no taxa that was particularly dominant. Populations were significantly higher during the rainy season (F = 37.9, df = 51,356, p<0.0001). The aggressive Dorylus was absent during the dry season, an indication that wet ground was its preference for foraging. This study was the first of its kind in the area, and can serve as a benchmark for future reference to ant taxa in the area.

This research paper aims to examine the prospects and problems of silk weavers of Kancheepuram, Tamilnadu. This study also examines the various services offered to the silk weavers, the problems encountered by the silk weavers and the various suggestions offered to remove bottlenecks and expectations and services offered. This study emphasizes weavers problems like lack of continuous work, power holidays, lack of expansion and modernization etc. The study also focusses on the prospects and problems arising out of emerging technological developments. To overcome the problems faced, the study would also offer certain suggestions to make use of technology for better prosperity. It is estimated that due to increase in technological evolutions in the textile industries, silk weavers, being cottage industries, there is wide gap because of the prevailing market conditions.

This work investigated the potential effects of dietary garlic ( Allium sativum ) crude polysaccharide (GPE) (0, 0.5, 1.0, 2.0, and 4.0%/kg diet) on growth, haematological parameters, whole body composition, and resistance against low pH in African catfish, Clarias gariepinus juveniles. At the end of 60 days, fish fed GPE supplemented diets had significantly increased ( P < 0.05) in growth parameters (weight gain, absolute growth rate, specific growth rate, and final weight compared to those fed a control diet. Similarly, feed utilization indices (feed intake, feed conversion ratio, and protein efficiency ratio) were significantly improved ( P < 0.05) in GPE supplemented fish compared to the control. Despite haematological indices being somewhat high in GPE supplemented fish, significant increase ( P < 0.05) was only observed in the red blood cells (RBC) (for those fed 0.5%, 1.0%, and 2.0%), and in mean corpuscular haemoglobin concentration (MCHC) (for those fed 0.5% and 1.0%). No significant difference ( P > 0.05) was observed in the cumulative survival among dietary groups following a challenge with low pH, except somewhat high survival in garlic-supplemented fish especially at 72 h. Similarly, no significant difference ( P > 0.05) was presented in the whole body composition and organo-somatic indices among groups. Based on the second order polynomial analysis, dietary inclusion level less than or equal to 1.88% of garlic/kg diet is estimated suitable to support growth, feed utilization, and ultimately health in C. gariepinus juvenile culture.

This book contains concept of biology and the exercise in English language that can help the readers to improve their English skill in biology. There are eight main contents in this book, which are the chemistry of life, an introduction of metabolisms, biotechnology, mechanisms of evolution, classification of living things,reproduction in plant, thermoregulation, and ecology. Hopefully, this book can help the readers to expand their knowledge about English for Biology.

This cross-sectional study was conducted in Ouba Debre-Tsehay District, Gamogoffa Zone, Southern Ethiopia from October 2013 to July 2014 with the objectives of estimating the prevalence of bovine trypanosomiasis and to assess the possible risk factors. Blood samples were collected from 384 randomly selected cattle from purposefully selected peasant associations with consideration of different age groups and both sexes. Buffy coat method was employed for parasitological survey and packed cell volume (PCV) determination was done. From the examined animals, 58 (15.1%; 95% CI: 11.7-19.6) were positive for trypanosome infection. In the area, Trypanosome congolense and Trypanosome vivax were the two identified Trypanosoma species with proportion of 60.3 and 27.6% , respectively and 12.1% mixed infection. Trypanosomiasis was observed as 13.8% in males and 15.9% in females out of these, 4.9 (95% CI: 1.0-13.7), 11 (95% CI: 5.8-18.4) and 20.1% (95% CI: 14.9-26.1) were found in animals <1year, between 1 and 3 years and above 3 years of age, respectively. Significant difference was observed between <1 year and >3 years of age (p<0.05). Based on body condition category, 8 (95% CI: 4.7-13.8), 16 (95%CI: 10.2-23.5) and 26.1% (95%CI: 17.3-36.6) were good, medium and poor conditioned animals, respectively and there was a significant association between good and poor condition animals (p<0.05). The recorded overall mean PCV in parasitaemic and aparasitaemic animals was 20.4 and 25.6%, respectively; it significantly varied (t=12.28, p = 0.00). Out of the parasitaemic and aparasitaemic animals, 77.6 and 16.6% were anemic, respectively (with PCV < 24%).
