Butterflies Of Sri Lanka
Sri Lanka is home to 245 species of butterflies with 23 of these being endemic to the island. Of the 245 species, 76, are listed as threatened nationally, while the Ceylon rose is designated as critically endangered. General description The majority of species are found in the foothills (up to elevation). A much smaller number of species are found above , while 20 species of butterfly are restricted to the low lying dry zone (below elevation). The number of butterflies peaks in two seasons during the year. The first of these is during the southwestern monsoon in the months of March to April. The second is during the northeastern monsoon which continues from September to October. Within Sri Lanka, thlatest revision of lepidopteransdescribed 1903 species with 58 families of butterflies and moths. Out of these 1903 species, 208 species are butterflies and 1695 species are moths. The family-wise number of butterfly species are: History of studies on butterflies The first s ...

Edgar Leopold Layard
Edgar Leopold Layard MBOU, (23 July 1824 – 1 January 1900) was a British diplomat and a naturalist mainly interested in ornithology and to a lesser extent the molluscs. He worked for a significant part of his life in Ceylon and later in South Africa, Fiji and New Caledonia. He studied the zoology of these places and established natural history museums in Sri Lanka and South Africa. Several species of animals are named after him. Early life and education Born in the Berti Palace, Florence, Italy, to an English family of Huguenot descent, Layard was the youngest of seven sons (two of the earlier siblings died in infancyLayard, E.L.

Air Pollution
Air pollution is the presence of substances in the Atmosphere of Earth, air that are harmful to humans, other living beings or the environment. Pollutants can be Gas, gases like Ground-level ozone, ozone or nitrogen oxides or small particles like soot and dust. It affects both outdoor air and indoor air. Natural sources of air pollution include Wildfire, wildfires, Dust storm, dust storms, and Volcanic eruption, volcanic eruptions. Indoor air pollution is often Energy poverty and cooking, caused by the use of biomass (e.g. wood) for cooking and heating. Outdoor air pollution comes from some industrial processes, the burning of Fossil fuel, fossil fuels for electricity and transport, waste management and agriculture. Many of the contributors of local air pollution, especially the burning of fossil fuels, also cause greenhouse gas emissions that cause climate change, global warming. Air pollution causes around 7 or 8 million deaths each year. It is a significant risk factor for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as the ...
