Species-specific allometric equations that provide estimates of biomass from measured plant attributes are currently unavailable for shrubs common to South Florida pine rocklands, where fire plays an important part in shaping the structure and function of ecosystems. We developed equations to estimate total aboveground biomass and fine fuel of 10 common hardwood species in the shrub layer of pi...
Forests can affect soil organic carbon (SOC) quality and distribution through forest types traits. However, much less is known about the influence of urban forests on SOC, especially in effects different types, such as coniferous broadleaved forests. Our objectives were to assess variability SOC content (SOC concentration (SOCC) density (SOCD)) determine key traits influencing SOC. Data from 16...
Forests are under stress due to variety of climatic and non-climatic factors. Therefore for suitably managing the forests, vulnerability forests needs be understood. The present paper attempts estimate various temperate Western Himalaya climate change by analyzing patterns different taxonomical indices, based on primary data i.e., vegetation data. presents a novel approach assessment field thro...
Although wall-to-wall, accurate, and up-to-date forest composition maps at the stand level are a fundamental input for many applications, ranging from global environmental issues to local forest management planning, countrywide mapping approaches on the tree type level remain rare. This paper presents and validates an innovative remote sensing based approach for a countrywide mapping of broadle...
Competition and climate influence in the basal area increment models for Mediterranean mixed forests
Competition plays a key role controlling tree growth in mixed forests. Contrary to monocultures, quantifying species mixing influence on suppose challenge since the presence of two or more requires estimate degree intra- and inter-specific competition among trees. Moreover, it is well known that aridity can also growth, especially Mediterranean Basin. In present context climate change, essentia...
The decomposition of litter from forest tree species is a fundamental process in the carbon (C) cycle terrestrial ecosystems and closely related to ongoing climate change. However, spatial distribution rate (k) its potential response changing air temperature (temperature sensitivity) remain poorly understood. Here, we estimated pattern plant k values China by performing random model based on 43...
