Abstract
Livelihood diversification is the key to a sustainable rural economy. The study aimed to assess livelihood diversity, determinants, and constraints among the scheduled caste families in Beraberia village of North 24 Parganas, West Bengal to plan a foolproof developmental program. Simple random sampling was followed to select a sample size 108 from the study area. The Simpson livelihood index formula was used to assess the level of livelihood diversification, and the Tobit model was used to find the determinants of the livelihood diversity index. A preferential ranking technique was followed to analyze the constraints in livelihood diversification. The most common livelihood activity in the study was agriculture, with an income contribution of 60.72%. Around 66 percent of the households had a medium to high livelihood diversity index. The Tobit regression model result showed that income, economic motivation, and access to credit were the significant determinants of livelihood diversification in the study area. At the same time, the family dependency ratio negatively influenced the Diversification index. Further, the constraint analysis in livelihood diversification revealed that lack of capital (RBQ 0.77) and livelihood assets (0.75) were significant impediments to livelihood diversification. The study suggests that government bodies must prioritize credit access and capacity building among SC families in rural areas to create more profitable and sustainable livelihoods among the weaker sections of society.

Abstract
True flies (Insecta: Diptera) are widely distributed and the key components in most ecosystems. The objective of this study was to identify the true flies’ diversity through DNA barcoding technique (658 bp sequence from the 5′-end of cytochromeoxidase I) in Bangladesh. Specimens were collected by a Malaise trap at Chittagong University Campus between April 2014 and March 2015. In this study, we examined 36476 sequences of 38267 true flies, and resulted 105 species, 109 genera, 54 subfamilies and 59 families. Among them 79 species, 69 genera, 12 subfamilies and 23 families are new country records. All the specimen records with the Barcode Index Numbers (BINs) (the species proxies), are available on the Barcode of Life Data System (BOLD).
