बायोम
बायोम (टेम्पलेट:Lang-en; टेम्पलेट:IPA-all) कौनों प्राकृतिक आवासक्षेत्र (हैबिटाट) में पावल जाए वाला बनस्पति (फ्लोरा) आ जियाजंतु (फौना) के समेकित रूप होखे लें [१]दुसरे शब्द में, बायोम एगो बिसाल इलाका होला जेकर अपने खास बनस्पति, माटी, जलवायु आ जियाजंतु सभ से पहिचान होले।[२]
बायोम के बर्गीकरण के कई गो तरीका अपनावल गइल बाड़ें; मुख्य रूप से पाँच गो बायोम प्रकार गिनावल जालें: पनिहा (एक्वाटिक), घासमैदान (ग्रासलैंड), बन, रेगिस्तान आ टुंड्रा बायोम। हालाँकि, इनहन में से कुछ के अउरियो उपप्रकार में बाँटल जा सके ला।[२] जइसे कि, एक्वाटिक बायोम के फ्रेशवाटर बायोम (मीठापानी के बायोम) आ मरीन बायोम (समुंद्री बायोम) में बाँटल जा सके ला।
Olson & Dinerstein (1998) biomes for WWF / Global 200
A team of biologists convened by the World Wildlife Fund (WWF) developed a scheme that divided the world's land area into biogeographic realms (called "ecozones" in a BBC scheme), and these into ecoregions (Olson & Dinerstein, 1998, etc.). Each ecoregion is characterized by a main biome (also called major habitat type).[३][४]
This classification is used to define the Global 200 list of ecoregions identified by the WWF as priorities for conservation.[३]
For the terrestrial ecoregions, there is a specific EcoID, format XXnnNN (XX is the biogeographic realm, nn is the biome number, NN is the individual number).
Biogeographic realms (terrestrial and freshwater)
- NA: Nearctic
- PA: Palearctic
- AT: Afrotropic
- IM: Indomalaya
- AA: Australasia
- NT: Neotropic
- OC: Oceania
- AN: Antarctic[४]
टेम्पलेट:Div col end The applicability of the realms scheme above - based on Udvardy (1975)—to most freshwater taxa is unresolved.[५]
Biogeographic realms (marine)
- Arctic
- Temperate Northern Atlantic
- Temperate Northern Pacific
- Tropical Atlantic
- Western Indo-Pacific
- Central Indo-Pacific
- Eastern Indo-Pacific
- Tropical Eastern Pacific
- Temperate South America
- Temperate Southern Africa
- Temperate Australasia
- Southern Ocean[६]
Biomes (terrestrial)
- Tropical and subtropical moist broadleaf forests (tropical and subtropical, humid)
- Tropical and subtropical dry broadleaf forests (tropical and subtropical, semihumid)
- Tropical and subtropical coniferous forests (tropical and subtropical, semihumid)
- Temperate broadleaf and mixed forests (temperate, humid)
- Temperate coniferous forests (temperate, humid to semihumid)
- Boreal forests/taiga (subarctic, humid)
- Tropical and subtropical grasslands, savannas, and shrublands (tropical and subtropical, semiarid)
- Temperate grasslands, savannas, and shrublands (temperate, semiarid)
- Flooded grasslands and savannas (temperate to tropical, fresh or brackish water inundated)
- Montane grasslands and shrublands (alpine or montane climate)
- Tundra (Arctic)
- Mediterranean forests, woodlands, and scrub or sclerophyll forests (temperate warm, semihumid to semiarid with winter rainfall)
- Deserts and xeric shrublands (temperate to tropical, arid)
- Mangrove (subtropical and tropical, salt water inundated)[४]
Biomes (freshwater)
According to the WWF, the following are classified as freshwater biomes:[७] टेम्पलेट:Div col
- Large lakes
- Large river deltas
- Polar freshwaters
- Montane freshwaters
- Temperate coastal rivers
- Temperate floodplain rivers and wetlands
- Temperate upland rivers
- Tropical and subtropical coastal rivers
- Tropical and subtropical floodplain rivers and wetlands
- Tropical and subtropical upland rivers
- Xeric freshwaters and endorheic basins
- Oceanic islands
Biomes (marine)
Biomes of the coastal and continental shelf areas (neritic zone):
- Polar
- Temperate shelves and sea
- Temperate upwelling
- Tropical upwelling
- Tropical coral[८]
