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 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 ...

William De Alwis
William De Alwis Seneviratne (1842–1916) was a Ceylonese artist and entomologist. With his brother George (dates unknown), William made a lasting contribution to the knowledge of the lepidoptera (butterflies and moths) of Ceylon. The brothers' father, Haramanis de Alwis Seneviratne (1792–1894) was a botanical illustrator who worked at the Botanical Gardens in Ceylon at Kalutara between 1818–1822 and Peradeniya from 1822–1861. He illustrated over 2,000 plants. William was appointed to succeed him to continue the work as a botanical artist. George Thwaites, the Director of the Botanical Garden at Peradeniya between 1849 and 1879, who was impressed by the de Alwis brothers' botanical drawings, recommended to W H Gregory, the Governor of Ceylon, that they should draw from nature the butterflies and moths of Ceylon. Thwaites supervised the drawings, many of which were illustrations of specimens that he had collected himself. The drawings were accurate and later used by a num ...

Environmental Effects Of Pesticides
The environmental effects of pesticides describe the broad series of consequences of using pesticides. The unintended consequences of pesticides is one of the main drivers of the negative impact of modern industrial agriculture on the environment. Pesticides, because they are toxic chemicals meant to kill pest species, can affect non-target species, such as plants, animals and humans. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. Other agrochemicals, such as fertilizers, can also have negative effects on the environment. The negative effects of pesticides are not just in the area of application. Runoff and pesticide drift can carry pesticides into distant aquatic environments or other fields, grazing areas, human settlements and undeveloped areas. Other problems emerge from poor production, transport, storage and disposal practices.Tashkent (1998)Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Pollution
Air pollution is the contamination of air due to the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. There are many different types of air pollutants, such as gases (including ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane, carbon dioxide and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and food crops, and may damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). Air pollution can be caused by both human activities and natural phenomena. Air pollution is a significant risk factor for a number of pollution-related diseases, including respiratory infections, heart disease, COPD ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domina ...

Bernard D'Abrera
Bernard d'Abrera (28 August 1940 – 13 January 2017) was an Australian entomological taxonomist and philosopher of science, particularly noted for his books on true butterflies (Papilionoidea) and larger moths of the world (Saturniidae and Sphingidae). Referred to as one of the world's best-known lepidopterists by ''The Daily Telegraph'', his work since 1982 was openly critical of evolution. Biography Bernard d'Abrera was a graduate of the University of New South Wales in Sydney, Australia. While at the university in 1964 he with a group of other students kidnapped an alligator from Taronga Zoo as a Foundation Day prank. Using 80 biology students as a shield, the group captured the animal in a bag and walked out through the turnstiles. The animal was returned after payment of a £100 ransom, which went towards establishing the first aboriginal scholarship of the University of New South Wales. He received his Bachelor of Arts in 1965, with a double major in History & Philosoph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
