Ecology

Ecology is the study of a community of biota, including the interactions with abiotic factors such as soils, water, and meteorological factors. The field of ecology addresses interactions of plants and animals including feeding behavior, selection of nesting or denning sites and competition among species. Time changes are particularly important, such as landscape changes arising from plant succession. Conservation of habitats is analyzed in order to determine the viability of not only individual species, but of the entire assemblage of flora, fauna and micro-organisms in a given ecosystem.

The Role of Botanic Gardens in Conservation of Medicinal Plant Species: A Case Study of Entebbe Bontanic Gardens Last Updated on 2014-10-21 11:20:56 A botanic garden is an institution holding documented collections of living plants for the purposes of scientific research, conservation, display and education. A botanic garden has been defined as a garden containing scientifically ordered and maintained collections of plants, usually documented and labeled, and open to the public for the purposes of recreation, education and research. Medicinal plant species are those that provide people with medicines to prevent diseases, maintain health or cure ailment. Therefore medicinal plants are important in the well being of people yet most people are not aware about these species or their medicinal value. Examples of these plants include Aloe vera, Hydnocarpus kurzii, Azadirachta indica and many others. Medicinal plant species are of great value to mankind and other animals but not much emphasis is laid on their conservation especially... More »
Sundarbans, Bangladesh Last Updated on 2014-10-19 18:16:11 The Sundarbans (21°30'- 22°30'N, 89°12'-90°18'E) are a World Heritage Site which consists of three wildlife sanctuaries (Sundarbans West, East and South) lying on disjunct deltaic islands in the Sundarbans Forest Division of Khulna District, close to the border with India and immediately west of the principal outflow of the Ganges, Brahmaputra and Meghna rivers. The Sundarbans belong to Bengalian Rainforest biogeographical province. 1977: All three wildlife sanctuaries established under the Bangladesh Wildlife (Preservation) (Amendment) Act, 1974, 1878: The three sanctuaries gazetted as forest reserves. 1996: The total area of wildlife sanctuaries extended; the entire Sundarbans is reserved forest, established under the Indian Forest Act, 1878. 1997: The Sundarbans inscribed on the World Heritage List. The total area of the Bangladesh... More »
Ecoregions of Bangladesh Last Updated on 2014-10-19 17:45:45 Bangladesh has five ecoregions: Sundarbans mangroves Sundarbans freshwater swamp forests Lower Gangetic Plains moist deciduous forests Mizoram-Manipur-Kachin rain forests Myanmar coastal rain forests The ecoregion lies in the vast delta formed by the confluence of the Ganges, Brahmaputra, and Meghna rivers. The maze of mangrove channels extends across southern Bangladesh and India's West Bengal State.The Sundarbans Mangroves ecoregion is the world's largest mangrove ecosystem. Named after the dominant mangrove species Heritiera fomes, locally known as sundri, this is the only mangrove ecoregion that harbors the Indo-Pacific region's largest predator, the tiger (Panthera tigris). Unlike in other habitats, here tigers live and swim among the mangrove islands, where they hunt scarce prey such as chital deer (Cervus axis), barking deer (Muntiacus muntjak), wild... More »
Bacteria Last Updated on 2014-10-12 18:54:28 Bacteria are any of a very large group of single-celled microorganisms that display a wide range of metabolic types, geometric shapes and environmental habitats—and niches—of occurrence.  Normally only several micrometers in length, bacteria assume the form of  spheres, rods, spirals and other shapes. Bacteria are found in a very broad gamut of habitats; for example, bacterial extremophiles that thrive in such places as hot springs, arctic environments, radioactive waste, deep sea oil seeps, deep Earth crustal environments, hypersaline ponds and within other living organisms. There are approximately 50 million bacterial organisms in a single gram of typical surface soil. The worldwide bacterial biomass exceeds that of all plants and animals on Earth. However, the majority of bacteria have not yet been characterised, Bacteria are members of the prokaryote... More »
Biodiversity fact sheet Last Updated on 2014-10-12 18:49:53 This ecology fact sheet was originally published by the Ecological Society of America (ESA). This fact sheet may be updated periodically; for the latest version, please see the ESA website. Click here to see more fact sheets from the Ecological Society of America.  The concept of biodiversity has provoked considerable debate and misunderstanding among the general public, decision-makers, and even the scientific community. Much has been published on the subject since its first appearance at the National Forum on BioDiversity in September 1986, the proceedings of which became the bestseller, BioDiversity. But what is biodiversity, what threatens it, why is it important, and what are ecologists doing to better understand it?   What is Biodiversity? Short for biological diversity, biodiversity includes all organisms, species, and... More »
