As is the usual case, the parents used the north-facing gap to arrive at the nest and the east-facing gap to leave the nest. Directly above the nest was also a smaller opening, which the parents used to descend vertically in an emergency.

    International Dragonfly Fund - Report 26 (2010): 1-36 1 The Superfamily Calopterygoidea in South China: taxonomy and distribution. Progress Report for 2009 surveys Zhang Haomiao* *PH D student at the Department of Entomology, College of Natural Resources and Environment, South China Agricultural University, Guangzhou 510642, China. Email: [email protected] Introduction Three families in the superfamily Calopterygoidea occur in China, viz. the Calo- pterygidae, Chlorocyphidae and Euphaeidae. They include numerous species that are distributed widely across South China, mainly in streams and upland running waters at moderate altitudes. To date, our knowledge of Chinese spe- cies has remained inadequate: the taxonomy of some genera is unresolved and no attempt has been made to map the distribution of the various species and genera. This project is therefore aimed at providing taxonomic (including on larval morphology), biological, and distributional information on the super- family in South China. In 2009, two series of surveys were conducted to Southwest China-Guizhou and Yunnan Provinces. The two provinces are characterized by karst limestone arranged in steep hills and intermontane basins. The climate is warm and the weather is frequently cloudy and rainy all year. This area is usually regarded as one of biodiversity “hotspot” in China (Xu & Wilkes, 2004). Many interesting species are recorded, the checklist and photos of these sur- veys are reported here. And the progress of the research on the superfamily Calopterygoidea is appended. Methods Odonata were recorded by the specimens collected and identified from pho- tographs. The working team includes only four people, the surveys to South- west China were completed by the author and the photographer, Mr.

These attributes have prompted studies of odonate life histories, behavior, and diet [2]. The fossil record of these species dates back to carboniferous period over 350 million years ago.

Deepor beel bird sanctuary lies between 26° 7' 52" N; 91° 38' 70" E in Kamrup district. A total of Life-Science Department, 39 species belonging to 5 families and 22 genera were recorded from Deepor beel bird sanctuary. We Assam University, Silchar also recorded Ceriagrion rubiae and Agriocnemis kalinga, which is the first formal record from Assam. In case of sub order Anisoptera (Dragonflies), family Libellulidae was the most dominant family.

Introduction The order Odonata is one of the most important and popular groups of insects. Dragonflies and damselflies both are togetherly known as Odonata. Odonata, dragonflies and damselflies, constitute a small, well known order of insects that are widely distributed over the world [15]. They are denizens of many aquatic ecosystems and their distribution covers a great deal of continuum from temporary to permanent water bodies [6].

    Maintenance and conservation of Dipterocarp diversity in tropical forests _______________________________________________ Mohammad Nazrin B Abdul Malik A thesis submitted in partial fulfilment of the degree of Doctor of Philosophy Faculty of Science Department of Animal and Plant Sciences November 2019 1 i Thesis abstract Many theories and hypotheses have been developed to explain the maintenance of diversity in plant communities, particularly in hyperdiverse tropical forests. Maintenance of the composition and diversity of tropical forests is vital, especially species of high commercial value. I focus on the high value dipterocarp timber species of Malaysia and Borneo as these have been extensive logged owing to increased demands from global timber trade. In this thesis, I explore the drivers of diversity of this group, as well as the determinants of global abundance, conservation and timber value. The most widely supported hypothesis for explaining tropical diversity is the Janzen Connell hypothesis. I experimentally tested the key elements of this, namely density and distance dependence, in two dipterocarp species. The results showed that different species exhibited different density and distance dependence effects. To further test the strength of this hypothesis, I conducted a meta-analysis combining multiple studies across tropical and temperate study sites, and with many species tested. It revealed significant support for the Janzen- Connell predictions in terms of distance and density dependence. Using a phylogenetic comparative approach, I highlight how environmental adaptation affects dipterocarp distribution, and the relationships of plant traits with ecological factors and conservation status. This analysis showed that environmental and ecological factors are related to plant traits and highlights the need for dipterocarp conservation priorities.
