Pollen From Kaziranga National Park To Decode Climate Change
NEW DELHI, (IANS) – Indian researchers have explored how pollen and non-pollen palynomorphs of Kaziranga National Park can help in the interpretation of climate in the region.
The KNP in Assam, a corridor for the immigration of members of the Indo-Malayan fauna into the Indian sub-region, is a critical reserve for tropical species, having served as a gene reservoir for these taxa during glacial periods.
To understand the effect of climate change on the biodiversity loss in national parks, scientists from the Birbal Sahni Institute of Palaeosciences (BSIP), an autonomous institution of the Department of Science and Technology (DST) developed a modern analog dataset based on NPPs from different vegetation settings across the KNP.
The research is the first holistic approach towards developing modern pollen and NPP analog that would be an accurate reference tool for the past herbivory and ecological studies in the tropical region of northeast India.
The study published in the journal Holocene for the first time helps in identifying marker pollen taxa recovered from surface soil samples in relation to the different vegetation and land use from KNP.
It could help public and wildlife management agencies to understand the association of flora and fauna, especially herbivores in national parks to conserve it for the current and future prospects, thus informing the National Biodiversity Mission.
