Research Interest
My research interests encompass plant ecology, environmental science, and climate change. I utilize observational, empirical, and modeling approaches, including satellite imagery, GIS tools, and mapping techniques, to investigate and comprehend ecological patterns such as plant traits, species distribution, and community structure. My work also addresses environmental challenges like habitat loss, plant invasion, and shifts in species distribution due to climate change particularly the threatened and economically important plants. My interests are also in developing innovative methods and solutions for restoring degraded lands, conserving endangered plant species, managing invasive plants, and mitigation urban heat.
Research Summary
Future climate change scenarios imply that species will thrive or fail based on their morphological, physiological, and demographic adaptations. Threatened species are at increased risk due to small population sizes and narrow genetic diversity. In the Indo-Burma biodiversity hotspot, we examined three endangered Ilex species that respond differently to climate change. Our study showed that Ilex khasiana will lose much of its habitat because it has a narrow niche and lives at high elevations. However, I. venulosa and I. embelioides might be able to locate new areas with suitable conditions since they have broader niches.
Heat waves in India can result in outbreaks of Citrus crop diseases. This problem is worsened by global warming. Wild relatives must be conserved to breed varieties resistant against ailment causing agents. Using ecological modeling based on niche theory, we predicted stable climatic regions of the six citrus species in India under future scenarios. Our models indicated that northeastern states had stable climates hence recommended establishing germplasm banks besides orchards for these plants within this region as an in situ conservation measure.
