  • Abstract Book, First National Conference on Zoology 2020
    First National Conference on Zoology Biodiversity in a Changing World 28-30 November 2020 Abstracts Organized By Supported By: Foreword It is our pleasure to welcome you to the First National Conference on Zoology: Biodiversity in a Changing World on November 28–30, 2020 on a virtual platform. This conference is organized by the Central Department of Zoology and its Alumni on the occasion of the 55th Anniversary of the Department. This conference is supported by the IUCN Nepal, National Trust for Nature Conservation, WWF Nepal and Zoological Society of London Nepal office. The Central Department of Zoology envisioned three important strategies; teaching, research and extension of its strategic plan 2019 – 2023. The First National Conference is one of the most important extension activities of the Department in collaboration with leading conservation organizations of the country. We believe extension activities including national conference will help to mainstream zoology and make priority agenda of the government for research, faunal conservation, national development and employment. The main theme of the conference is “Biodiversity in a Changing World”, which is of utmost importance given global changes that species, ecosystem processes, landscapes and also people currently have to face together. Excessive exploitation of biological resources as well as global changes and the degradation of the natural environment have large-scale effects, some of which directly lead to the extinction of species and impacts on the health of people. The Conference provides us with the opportunity to meet, connect and learn from each other, share latest research results, and eventually envisage feasible means of conciliating human development and protect health of ecosystem and people with biodiversity conservation.

  • Floral Relatioships of Bees in Selected Areas of Sri Lanka
    Cey. J. Sci. (Bio. Sci.) Vol. 34,2005,27-45 FLORAL RELATIOSHIPS OF BEES IN SELECTED AREAS OF SRI LANKA W. A. Inoka P. Karunaratne, Jayanthi P. Edirisinghe* and C. V. Savithri Gunatilleke1 Department of Zoology, 'Department of Botany, Faculty of Science, University of Peradeniya, Peradeniya, SriLanka. ABSTRACT This study represents the very first attempt to record the floral relations of bees of Sri Lanka. Floral hosts of 117 bee species in 35 genera were recorded based on floral visits, pollen carriage and special behaviour at flowers. Floral hosts comprised 154 plant species in 112 genera and 44 families. Majority of the floral hosts were native plants of which most were weeds in their respective habitats. The exotic naturalized weed, Hyptis suaveolense was exceptional in attracting 60 bee species. All five species of social bees and majority of the solitary bees were polylectics foraging on pollen of a variety of unrelated flowers. Seven solitary bee species were recognized as oligolectics foraging on species of Convolvulaceae and Malvaceae having large spiny pollen. Sonication at tubular anthers of certain Solanaceae and Melastomataceae flowers having concealed pollen was observed in 12 species of solitary bees. Nectar robbing by males of five species of solitary bees was recorded from certain tubular-shaped flowers. Floral relationships suggest that most bees are generalists and a few have become specialized to forage on specific groups of flowers. The information gathered would be useful in pollination studies and in the management and conservation of bees.

    Crespi & Abbot: Evolution of Kleptoparasitism 147 THE BEHAVIORAL ECOLOGY AND EVOLUTION OF KLEPTOPARASITISM IN AUSTRALIAN GALL THRIPS BERNARD CRESPI AND PATRICK ABBOT1 Behavioural Ecology Research Group, Department of Biological Sciences Simon Fraser University, Burnaby BC V5A 1S6 Canada 1Current address: Department of Ecology and Evolutionary Biology, University of Arizona ABSTRACT We used a combination of behavioral-ecological and molecular-phylogenetic data to analyze the origin and diversification of kleptoparasitic (gall-stealing) thrips in the genus Koptothrips, which comprises four described species that invade and breed in galls induced by species of Oncothrips and Kladothrips on Australian Acacia. The ge- nus Koptothrips is apparently monophyletic and not closely related to its hosts. Two of the species, K. dyskritus and K. flavicornis, each appears to represent a suite of closely-related sibling species or host races. Three of the four Koptothrips species are facultatively kleptoparasitic, in that females can breed within damaged, open galls by enclosing themselves within cellophane-like partitions. Facultative kleptoparasitism may have served as an evolutionary bridge to the obligately kleptoparasitic habit found in K. flavicornis. Evidence from phylogenetics, and Acacia host-plant relation- ships of the kleptoparasites and the gall-inducers, suggests that this parasite-host system has undergone some degree of cospeciation, such that speciations of Kopto- thrips have tracked the speciations of the gall-inducers. Quantification of kleptopar- asitism rates indicates that Koptothrips and other enemies represent extremely strong selective pressures on most species of gall-inducers. Although the defensive soldier morphs found in some gall-inducing species can successfully defend against Koptothrips invasion, species with soldiers are still subject to high rates of successful kleptoparasite attack.

Box 62000-00200 Nairobi, Kenya Abstract—Bees provide important pollination services that maintain native plant populations and ecosystem resilience, which is critical to the conservation of the rich and endemic biodiversity of Kaya forests along the Kenyan Coast. This study examined bee composition and floral resources from the forest core to the surrounding farmlands around Kaya Muhaka forest. In total, 755 individual bees, representing 41 species from three families were recorded: Apidae, Halictidae and Megachilidae. Overall, Apidae were the most abundant with a proportion of 76% of the total bee individuals, Halictidae at 14% and Megachilidae at 10%. Bee composition was similar between forest edge and crop fields as compared to forest core and fallow farmlands. We found a significant decrease in bee diversity with increasing distance from the forest to the surrounding farming area. A high abundance of bees was recorded in fallow farmland, which could be explained by the high abundance of floral resources in the habitat. We found floral resources richness to significantly affect bee species richness. These findings are important for understanding the effects of land use change on insect pollinators and their degree of resilience in disturbed habitats.

  • Diversity of Bees at Different Altitudes in the Knuckles Forest Reserve
    Cey. J. Sci. (Bio. Sci.) 37 (1): 61-72, 2008 DIVERSITY OF BEES AT DIFFERENT ALTITUDES IN THE KNUCKLES FOREST RESERVE W.A.I.P. Karunaratne* and J.P. Edirisinghe Department of Zoology, Faculty of Science, University of Peradeniya, Sri Lanka. Accepted 14 May 2008 ABSTRACT A year around survey of bees carried out in the Knuckles mountain range at different altitudes having specific habitat types highlighted the effect of altitude and habitat on the presence and abundance of bees. The study was based on hourly counts of bees made once every month in five selected habitats; natural forest, managed cardamom, Patana grassland, cultivated home gardens and mixture of habitats including home gardens, scrublands and rice fields, situated at different altitudes ranging from 150 – 1350 m. The study recorded a total of 62 bee species belonging to 26 genera in 4 families representing more than ¾ of the total bee fauna recorded for Sri Lanka. The distribution of bee species decreased with increasing elevation. Areas under cardamom cultivation harboured the lowest number of bee species. Shannon diversity index gave the highest score for the bee diversity in home gardens. The finding of this study highlights the fact that the highest diversity of bees is at lower elevations where the climate is comparatively warmer. Furthermore, at lower elevations due to human settlements, the vegetation comprises a mixture of cultivated crops, flowering herbs and patches of natural vegetation providing a ready source of pollen and nectar for bees throughout the year. Key Words: Knuckles Forest Reserve, bees, altitude, climate, vegetation INTRODUCTION The climate, which is a reflection of the pollen particularly for bees that may play an altitude and latitude plays an important role in the important role in the maintenance of the flora distribution of plants and animals in the world through pollination.

In spite of the fact that the Hymenoptera of Barkuda were not diligently collected, a fairly representative collection has been 1nade and a report on them will not, I think J be \vithout value. I have not attempted to deal with the few parasitic forms collect­ ed, nor with the ants, but of the latter it may be nlentioned that a race of Camponot1'('s compressus, and PhidQle rho1nbinoda are not uncommon on the island. 1 Elsewhere in these reports Dr. Annandale has made some interesting bionolnic notes on these insects. Like the butterflies, the Hymenoptera are represented in the main by common and \videspread species, and many forms which occur on the neighbouring islands and on the mainland are here either scarce, or entirely absent. The fossorial families are fairly well represented. Mutillids are scarce, Scoliids likewise, but the Pompilidae and Sphegidae are COnlmon. M-acromeris violaceae and Sceliphron v£olaceum are the most abundant fossorial hymenop­ terons on the island. Individuals of the various species of solitary wasps found on Barkuda are rather scarce, and those of the only two species of social wasps mentioned in the list, abundant. The common yellow wasps (Polistes hebraeus) are not represented in the collection, but the species is one which I have occasionally seen. Individuals of the commoner species of Apidae are abundant, the larger forms being found chiefly round the pea Crotolaria striata and the abundant shrub Glycosmis pentaPh)J/la; the smaller, as N omia oxybeloides J in low herbage.
