Modelling of evapotranspiration using land surface energy balance and thermal infrared remote sensing
Tropical Ecology - - 2020
Accurate estimation of crop evapotranspiration (ET) is a key factor in crop water scheduling. The objective of this study was to estimate ET from the high-resolution satellite remote sensing data with integration of in situ observation. The surface energy balance model, Mapping Evapotranspiration with Internalized Calibration (METRIC) was utilised in this study for its simplicity, advantages, and ......
Synergetic use of in situ and hyperspectral data for mapping species diversity and above ground biomass in Shoolpaneshwar Wildlife Sanctuary, Gujarat
Tropical Ecology - Tập 61 - Trang 106-115 - 2020
Biodiversity loss in tropical forests is rapidly increasing, which directly influence the biomass and productivity of an ecosystem. In situ methods for species diversity assessment and biomass in synergy with hyperspectral data can adeptly serve this purpose and hence adopted in this study. Quadrat sampling was carried out in Shoolpaneshwar Wildlife Sanctuary (SWS), Gujarat, which was used to comp......
Elucidating space based observations of solar induced chlorophyll fluorescence over terrestrial vegetation of India
Tropical Ecology - Tập 61 - Trang 32-41 - 2020
Remotely sensed plant fluorescence signals have the potential to facilitate a better understanding of vegetation photosynthetic dynamics. Space based observations of solar-induced chlorophyll fluorescence (SIF) provides an alternative non-invasive approach to investigate gross primary production (GPP), a key element of ecological research. Orbiting carbon observatory (OCO-2) is providing continuou......
Unveiling tree diversity and carbon density of homegarden in the Thodupuzha urban region of Kerala, India: a contribution towards urban sustainability
Tropical Ecology - Tập 62 - Trang 508-524 - 2021
The present study aimed to assess the role of homegarden (HG) in safeguarding the tree diversity and carbon (C) density or storage in the Thodupuza urban region of Idukki district in Kerala, India. A stratified random approach was used for selecting the four homegardens (HGs) with a size of 1hectare (ha). The study mainly focused on species richness, diversity, above ground biomass, carbon, correl......
Applicability of monitoring protocols developed for active restoration projects in the evaluation of passive restoration of a subtropical riparian forest in Brazil

Culturable microbial diversity in the rhizosphere of different biotypes under variable salinity
Tropical Ecology - Tập 61 - Trang 291-300 - 2020
The microbial diversity in the rhizosphere of different biotypes is influenced by different factors like plant species, root exudates and soil environment. Culturable microbial diversity in the rhizosphere of six biotypes (Chenopodium murale (CM), Spergula arvensis (SA), Launaea nudicaulis (LN), Brassica juncea (BJ), Phalaris minor (PM) and Triticum aestivum (TA)) growing in variable saline enviro......
Tree diversity and community composition in sacred forests are superior than the other community forests in a human-dominated landscape of Meghalaya
Tropical Ecology - Tập 61 - Trang 84-105 - 2020
Tree diversity and community composition in six sacred forests (SF) of Meghalaya were compared with those of six adjacent community forests (CF) to understand how protection provided to sacred forests by the communities impacts their diversity and community characteristics. The SFs harboured a greater number of tree species (187) compared to the CFs (56). Tree density in the SFs ranged from 750 tr......
Patterns of woody species diversity and structure in Thalewood House permanent preservation plot in Bannerghatta National Park, Bangalore, India
Tropical Ecology - Tập 62 - Trang 626-643 - 2021
A permanent forest dynamics study plot was established in Bannerghatta National Park (BNP) to understand the impact of climatic variability on deciduous forest trees. A 1 ha (100 m × 100 m) Permanent Preservation Plot (PPP) was established following the Centre for Tropical Forest Science (CTFS) protocol. All the woody plants (trees, shrubs, climbers) greater than 1 cm diameter at breast height (db......
Digital hemispherical photographs and Sentinel-2 multi-spectral imagery for mapping leaf area index at regional scale over a tropical deciduous forest
Tropical Ecology - - Trang 1-13 - 2024
The leaf area index (LAI) provides valuable input for modeling climate and ecosystem processes. However, ground-based observations are necessitated across various phenophases from dense tropical forests for a better understanding in terms of their contribution to carbon fixation. In this study, Digital Hemispherical Photography (DHP) was used for LAI observation from Similipal Biosphere Reserve, a......
The effect of elevation on species richness in tropical forests depends on the considered lifeform: results from an East African mountain forest
Tropical Ecology - Tập 60 - Trang 473-484 - 2019
Elevation gradients in tropical forests have been studied but the analysis of patterns displayed by species richness and elevation have received little attention. We examined whether the effect of elevation on species richness varies according to forest lifeforms and the main plant families in the Kahuzi-Biega National Park, within the Albertine Rift. We established 20 1-ha plots from 810 to 2760 ......
