Mangrove forest coastal ecosystems contain significant amount of carbon stocks and contribute to approximately 15% the total sequestered in ocean sediments. The present study aims at exploring ability Earth Observation EO-1 Hyperion hyperspectral sensor estimating aboveground mangrove forests. Bhitarkanika has been used as case study, where field measurements biomass were acquired simultaneously with satellite data. spatial distribution most dominant species was identified using Spectral...
Approaches estimating landscape effects on biodiversity frequently focus a single extent, finding one 'optimal' or use narrow extents. However, species perceive the environment in different ways, select habitat hierarchically, and respond to multiple selection pressures at extents that best predict each pressure. We aimed assess multi-scale relationships between primary productivity occurrences abundances. used approach, called 'scalograms', level of productivity, form Dynamic Habitat...
Abstract Aerosol climatology during typical haze dominating period over South and Southeast Asia was explored using several Earth‐Observing A‐Train satellite products retrieved in between 2010 2020. Comparatively high aerosol optical depth (AOD) with dominance of fine UV‐absorbing aerosols are noted across the Indo‐Gangetic plain, (IGP; AOD: 0.58; UVAI: 0.74) against weak (SEA; 0.26; 0.07). Among inland IGP sites, decadal mean AOD resembles Lahore (0.72 ± 0.45), Delhi (0.81 0.46), Kanpur...
Geo-informatics technology has dynamic role in mapping, monitoring and management of forest resources. The transformation cover its analysis on the earth’s surface are essential for understanding associations interactions between natural phenomena living organism, especially human. Also deforestation is a major reason global warming one origin keys enhancement greenhouse effect climate change. present study grounded 3S assessment LU/LC changes within area Dalma Wildlife Sanctuary (DWLS)...
The status of reefs in Palk Bay and the Gulf Mannar was studied during April-May 2016 following a bleach alert, as sea surface temperature recorded sudden increase from 30.5C to 34.0C Mannar.About 71.48% 8.9% corals 46.04% 3.78% Thoothukkudi group Islands were found bleached, showing clearly decreasing trend north south, which could be attributed corresponding pattern intensity SST study sites.Observations bleaching patterns among different life-forms showed 68% bleached massive forms.It...
The integration of ecological and atmospheric characteristics for biodiversity management is fundamental long-term ecosystem conservation drafting forest strategies, especially in the current era climate change. explicit modelling regional responses their impact on individual species a significant prerequisite any adaptation strategy. present study focuses predicting distribution Rhododendron arboreum, medicinal plant found Himalayan region. Advanced Species Distribution Models (SDM) based...
Detection and classification of crown trees properties assessment their health status have raised much interest for the scientists from forest environmental sciences due to essential role in landscape ecology forestry management. The present study proposes a method based on consumer-based UAVs deep learning techniques detecting individual orchard assessing key characterising status. In proposed scheme, Mask R-CNN model is used mapping each tree morphometrical property such as height width....
The new COVID-19 coronavirus disease has emerged as a global threat and not just to human health but also the economy. Due pandemic, most countries affected have therefore imposed periods of full or partial lockdowns restrict community transmission. This had welcome unexpected side effect that existing levels atmospheric pollutants, particularly in cities, temporarily declined. As found by several authors, air quality can inherently exacerbate risks linked respiratory diseases, including...
Animal communication plays a crucial role in biology, yet the wide variability vocalizations is not fully understood. Previous studies birds have been limited taxonomic and analytical breadth. Here, we analyse an extensive dataset of >140 000 recordings from 8450 bird species, representing nearly every avian order family, under structural causal model framework, to explore influence eco-evolutionary traits on acoustic frequency characteristics. We find that body mass, beak size, habitat...
Forest Canopy Density (FCD) is defined as one of the key parameters to assess ecological condition a forest.The Present study deals with estimating change in forest canopy density using remote sensing techniques for last decade i.e., from 2008 2018 West Singhbhum District.Biophysical models like Advanced Vegetation Index (AVI), Bare Soil (BI) and Shadow (SI) are overlaid achieve FCD two time periods an overall accuracy 86% 82% 2018.The final classified into five classes namely High forest,...
Abstract The unprecedented increase in the Sea Surface Temperature (SST) warming climate yield stress to system and pose severe threats marine ecosystem. Marine Heatwaves (MHWs) Cold Spells (MCSs) are two extreme events related SST variability. For better management of ocean productivity, ecosystem, services, fisheries, understanding seasonal discrepancies rather than annual documentation MHWs MCSs metrics is more utilitarian. This study documents decadal changes over Tropical Indian Ocean...
Forest degradation is considered to be one of the major threats forests over globe, which has considerably increased in recent decades. Forests are gradually getting fragmented and facing biodiversity losses because climate change anthropogenic activities. Future prediction forest spatiotemporal dynamics fragmentation imperative for generating a framework that can aid prioritizing conservation sustainable management practices. In this study, random algorithm was developed applied series...
Interband information overlapping enhances redundancy in hyperspectral data. This makes identification of application-specific optimal bands essential for obtaining accurate about foliar traits. The current study investigated the performance three novel Band Selection (BS) algorithms (i.e. Chi-squared-statistics based attribute evaluator (CSS), Recursive elimination features-based (REF) and Correlation-based subset (CBS)) identifying spectral Airborne Visible/Infrared Imaging...
