Environment & Biodiversity MCQs

Notes:
The Hukawang Valley is an isolated valley in Myanmar (Burma), roughly 5,586 square miles in area. The Burmese government has also designated 6500 square kilometre of the valley as the protected forest reserve. It is the world’s largest tiger reserve.

Notes:
Sunabeda Wildlife Sanctuary is located in the state of Odisha (Nuapada district). It forms the catchment area of the Jonk River. Wild animal like tiger, leopard, Indian Gaur, sloth bear, barking deer, wild boar and blue bull are found in this sanctuary. Common langur and rhesus monkey are also evident in this park.

Notes:
The Intergovernmental Panel which is an intergovernmental body of the United Nations, was founded in the year 1988 by Bert Bolin. Its headquarter is located in Geneva, Switzerland. Its objective is to provide scientific information that is relevant to understanding the scientific basis of the risk associated with climate change and its natural, political, economic impacts and possible remedies.

Notes:
Valmiki National Park is a important Tiger Reserve and Wildlife Sanctuary which is located in the state of Bihar (Champaran district, India-Nepal border). The river Gandak flows beside the sanctuary.

Notes:
The United Nation Environment Programme World Conservation Monitoring Centre is an executive agency of UN Environment Programme, which is based in Cambridge (UK). It was previously managed by IUCN, UN Environment Programme and WWF.

Notes:
Aanaimalai Tiger Reserve was also known as Indira Gandhi Wildlife Sanctuary and National Park is located in the state of Tamil Nadu. The practice of sliding timber logs down the hills from a place located in the northeast corner of the park is named as “Topslip”. It is a famous tourist attraction.

Notes:
10 Biogeographic zones are Trans Himalayan zone, Himalayan zone, Desert zone, Semiarid zone, Western ghat zone, Deccan plateau zone, Gangetic plain zone, North east zone, Coastal zone and Islands present near the shore line

Notes:
Carbon Dioxide is associated with the Ocean Acidification and is emitted from combustion, factories and respiration of living organisms. When CO2 dissolved in the Ocean water, it creates Carbonic Acid (H2CO3) and increases the Hydrogen Ion (H+) concentration in the ocean.

Notes:
SEAWEEDS (algae) are good indicators of heavy metal levels in marine environments and could be used for monitoring such pollutants in seas. According to a new study in the Gulf of Kutch, which receives discharges containing heavy metals from several industries, various species of brown, red and green algae accumulate heavy metals from seawater and sediments. Heavy metals enter various organisms and trigger tissue damage. They generate reactive oxygen species, such as hydrogen peroxide, which break down proteins and lipids, degrade DNA, and cause cell deaths. The study was conducted at Vadinar and Sikka in the Gulf of Kutch. In recent years, such coastal regions have seen rapid industrialisation. The researchers measured the levels of heavy metals in various species of red, brown and green algae, in seawater and sediments and found that iron, manganese and zinc concentrations were generally high in all the algae species. Large amounts of cadmium and zinc were also found.

Notes:
The best time to acquire satellite images for vegetation analysis is during the post-monsoon period, specifically in October and November. The tropical monsoon deciduous forest has the highest canopy growth during the months of August, September, and October.
