Bhitarkanika Wildlife Sanctuary
Bhitarkanika Mangroves is a mangrove wetland in Odisha, India, covering an area of in the Brahmani River and Baitarani River deltas. History The Bhitarkanika Mangroves were zamindari forests until 1952, when the government of Odisha abolished the zamindari system, and put the zamindari forests in the control of the state forest department. In 1975, an area of was declared the Bhitarkanika Wildlife Sanctuary. The core area of the sanctuary, with an area of , was declared Bhitarkanika National Park in September 1998. The Gahirmatha Marine Wildlife Sanctuary, which bounds the Bhitarkanika Wildlife Sanctuary to the east, was created in September 1997, and encompasses Gahirmatha Beach and an adjacent portion of the Bay of Bengal. Bhitarkanika Mangroves were designated a Ramsar Wetland of International Importance in 2002. Flora and fauna About 62 mangrove species occur in the Bhitarkanika Mangroves, including ''Avicenna'', ''Bruguiera'', '' Heritiera'' and ''Rhizophora''. Rep ...

Indomalayan Realm
The Indomalayan realm is one of the eight biogeographic realms. It extends across most of South and Southeast Asia and into the southern parts of East Asia. Also called the Oriental realm by biogeographers, Indomalaya spreads all over the Indian subcontinent and Southeast Asia to lowland southern China, and through Indonesia as far as Sumatra, Java, Bali, and Borneo, east of which lies the Wallace line, the realm boundary named after Alfred Russel Wallace which separates Indomalaya from Australasia. Indomalaya also includes the Philippines, lowland Taiwan, and Japan's Ryukyu Islands. Most of Indomalaya was originally covered by forest, and includes tropical and subtropical moist broadleaf forests, with tropical and subtropical dry broadleaf forests predominant in much of India and parts of Southeast Asia. The tropical forests of Indomalaya are highly variable and diverse, with economically important trees, especially in the families Dipterocarpaceae and Fabaceae. Major ecol ...

Rhizophora
''Rhizophora'' is a genus of tropical mangrove trees, sometimes collectively called true mangroves. The most notable species is the red mangrove ('' Rhizophora mangle'') but some other species and a few natural hybrids are known. ''Rhizophora'' species generally live in intertidal zones which are inundated daily by the ocean. They exhibit a number of adaptations to this environment, including pneumatophores that elevate the plants above the water and allow them to respire oxygen even while their lower roots are submerged and a cytological molecular "pump" mechanism that allows them to remove excess salts from their cells. The generic name is derived from the Greek words ῥίζα (''rhiza''), meaning "root," and φορός (''phoros''), meaning "bearing," referring to the stilt-roots. The beetle '' Poecilips fallax'' is a common pest of these trees, especially ''Rhizophora mucronata'' and '' Rhizophora apiculata''. This beetle (related to carver beetles) lays its eggs in the ...

Ecoregions Of India
An ecoregion (ecological region) is an ecological and geographic area that exists on multiple different levels, defined by type, quality, and quantity of environmental resources. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Ecoregions are also known as "ecozones" ("ecological zones"), although that term may also refer to biogeographic realms. Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framewo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove Ecoregions
A mangrove is a shrub or tree that grows mainly in coastal saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have particular adaptations to take in extra oxygen and remove salt, allowing them to tolerate conditions that kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse due to convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs and became widely distributed in part due to the movement of tectonic plates. The oldest known fossils of mangrove palm date to 75 million years ago. Mangroves are salt-tolerant ( halophytic) and are adapted to live in har ...

Mangroves In India
Mangroves in India are coastal ecosystems characterized by salt-tolerant trees and shrubs, found predominantly along the eastern and western coastlines and in the Andaman and Nicobar Islands. India hosts some of the largest mangrove forests in the world, including the Sundarbans, Bhitarkanika, and the Krishna-Godavari delta regions. The total mangrove cover in India is 4,991.68 sq km, which accounts for 0.15% of the country's total area. Indian mangroves form 3% of the South Asia’s mangrove cover. Major Mangrove Forests in India India hosts several prominent mangrove forests, each with unique ecological characteristics: * Sundarbans (West Bengal): The Sundarbans is the largest mangrove forest in India and is part of the Ganges delta. It spans India and Bangladesh and is home to the endangered Royal Bengal tiger (Panthera tigris), saltwater crocodiles, and diverse bird species. The Sundarbans are a UNESCO World Heritage Site, recognized for their unique biodiversity and exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Olive Ridley Turtle
The olive ridley sea turtle (''Lepidochelys olivacea''), also known commonly as the Pacific ridley sea turtle, is a species of turtle in the family Cheloniidae. The species is the second-smallest and most abundant of all sea turtles found in the world. ''L. olivacea'' is found in warm and tropical waters, primarily in the Pacific and Indian Oceans, but also in the warm waters of the Atlantic Ocean. This turtle and the related Kemp's ridley sea turtle are best known for their unique synchronised mass nestings called ''arribadas'', where thousands of females come together on the same beach to lay eggs. Taxonomy The olive ridley sea turtle may have been first described as ''Testudo mydas minor'' by Georg Adolf Suckow in 1798. It was later described and named ''Chelonia multiscutata'' by Heinrich Kuhl in 1820. Still later, it was described and named ''Chelonia olivacea'' by Johann Friedrich von Eschscholtz in 1829. The species was placed in the subgenus ''Lepidochelys'' by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heronry
A heronry, sometimes called a heron rookery, is a breeding ground for herons. Notable heronries Although their breeding territories are often on more protected small islands in lakes or retention ponds, herons breed in heronries (or also called rookeries, especially since other birds join them like spoonbills, storks, and cormorants). Some of the notable heronries are: Asia * Kaggaladu Heronry is in Karnataka state of India. This heronry, in the Tumkur district of Karnataka, was first made known to the outside world in 1999 by members of the Tumkur-based NGO Wildlife Aware Nature Club.

Bird Migration
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of Procellariiformes, tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Monitor
The Asian water monitor (''Varanus salvator'') is a large varanid lizard native to South and Southeast Asia. It is widely considered to be the second-largest lizard species, after the Komodo dragon. It is distributed from eastern and northeastern India and Bangladesh, the Andaman and Nicobar Islands, Sri Lanka, through southern China and Hainan Island in the east to mainland Southeast Asia and the islands of Sumatra, Borneo, Java, Lombok, the Riau Archipelago, and Sulawesi. It is one of the most widespread monitor lizards. The Asian water monitor has a natural affinity towards water, inhabiting the surroundings of lakes, rivers, ponds, swamps and various riparian habitats, including sewers, city parks, and urban waterways. It is an excellent swimmer and hunts fish, frogs, invertebrates, water birds, and other types of aquatic and amphibious prey. Due to its apparently large, stable population, it is currently listed as Least Concern on to the IUCN Red List. Etymology The ge ...
