 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Diversity of Stingless Bees (Apidae: Meliponini) in Thong Pha Phum District, Kanchanaburi Province, Thailand) ผู้เขียน: ยุวรินทร์ บุญทบ,  ดร.สาวิตรี มาไลยพันธุ์, รองศาสตราจารย์ , Kosol Chareansom, ดร.เดชา วิวัฒน์วิทยา, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractStingless bees were observed in four types of undisturbed forest: dry dipterocarp forest (DDF), upper mixed deciduous forest (UMDF), lower mixed deciduous forest (LMDF) and dry evergreen forest (DEF) during April 2004 to March 2005 to determine the diversity and abundance of stingless bees. Monthly sampling was performed using honey-bait traps. Diversity was analysed using the Shannon- Weiner diversity index. Species abundance was computed for each forest type. Three genera and eleven species (Trigona ventralis, T. collina, T. sirindhornae, T. terminata, T. apicalis, T. thoracica, T. canifrons, T. fuscobalteata, T. melina, Pariotrigona pendleburyi and Lisotrigona cacciae) were recorded; Trigona ventralis, T. sirindhornae, T. collina and T. terminata were the most abundant. Species diversity indices ranged from 0.63 (DDF) to 0.86 (LMDF). Species richness and abundance data indicated the following clustering of forest types based on the stingless bee fauna: (((LMDF+UMDF) + DDF) + DEF). Stingless bees were most abundant during cooler, drier months and in seasons and forest types where the percentage of light transmittance was the greatest. |
