The Cost

Reduction in the number of pollinator species per plant species is a mechanism that may lower the cost of pollen transfer. Using efficient pollinators may have an evolutionary significance. It is hypothesized that an evolutionary trend from many pollinators to few pollinators per plant species should be observable when species from ancestral versus recently derived monophyletic taxon are compared. Three different orchid phylogenetic sequences are used; two of the phylogenies show a reduction in the number of pollinator species per orchid species from the most ancestral to the most recently derived subfamilies. The third classification did not show this trend. It is thus possible to observe macroevolution of pollinator specialization of a monophyletic plant taxon. Key words: evolution, pollination, systematics, Orchidaceae, evolutionary ecology.

Scientific forest management is an emerging need for managing existing natural forests of Nepal on the basis of silvicultural intervention. The study was carried out in Lumbini Collaborative Forest at Rupandehi District of Nepal, where Sal (Shorea robusta) forests are being managed under Irregular Shelterwood System with eighty years of cutting cycle since 2011–2012. The study was purposed to find out the intial effects of silvicultural intervention on plant species diversity and regeneration of Sal forest. The vegetative sampling was done using quadrate method based on the principle of simple random sampling both in the managed as well as the unmanaged parts of forest. The study found out remarkable increase in regeneration as well as decrease in plant diversity in the managed first and second-year stands (Block I and Block II respectively) as compared to the unmanaged stand (Block III) at its initial level of implementation. The mean value of diversity, richness, evenness, dominance index and regeneration of S. robusta varied significantly (p?0.05) between the managed blocks (stands). The seedling density of S. robusta was found higher in the managed blocks (Block I and Block II) as compared to the unmanaged one (Block III) in terms of height class. The study recommends implementation of Irregular Shelterwood System for managing the existing degraded Sal forests of the Terai region of Nepal, however, its long term effects on plant species diversity should be further studied in detail.Banko Janakari, A Journal of Forestry Information for NepalVol. 25, No. 1Page: 20-29

A study of the plant diversity of Sandwip Island has been conducted during July 2008 to April 2011 in order to document plant species used as traditional herbal medicine. A total of 111 species under 93 genera of 53 families have been documented which are used for the treatment of 48 diseases/illness. The local people of the island mostly depended on herbal medicine for their primary health care. Twenty one recorded medicinal plant species are used for the treatment of various types of pain, 14 each for dysentery and rheumatism, 8 each for cough and haemorrhages, 7 for skin diseases, 6 for worms, 5 for boils, 4 each for jaundice and fracture, 3 each for chicken pox, fever and diabetes and 54 for other diseases.DOI: http://dx.doi.org/10.3329/bjpt.v20i1.15463Bangladesh J.

This study presents taxonomic information on 468 plant species belonging to 326 genera and 85 families of the angiospermic class Magnoliopsida (dicotyledones) from Narsingdi district of Bangladesh. In this area, Fabaceae with 53 species of 37 genera is the largest family, followed by Asteraceae with 25 species of 24 genera and Rubiaceae with 21 species of 17 genera. Ficus with eight species is appeared as the largest genus, which is followed by Persicaria and Solanum with seven species each, Lindernia with six species, Phyllanthus with five species, and Acacia, Amaranthus, Senna, Sida and Trichosanthes with four species each. Herbs are comprised of 230 (49.14%) species that are followed by trees of 120 (25.64%) species, and shrubs of 118 (25.21%) species. The similarity measured by Jaccard coefficient shows that the six upazilas of Narsingdi district are relatively more similar (75.47%) in their species composition if they are compared all together. However, the similarities vary from 9.03% to 50% if only two upazilas are compared. In this district, total 333 species have been distinguished as economically useful. The species Rauvolfia serpentina of Apocynaceae, Geophila repens of Rubiaceae and Acmella radicans of Asteraceae have been assessed as Endangered (E) in this district. Bangladesh J.
