“…Variations in C concentration between biomes were small, suggesting that C concentration is relatively constant for species across environments, as already reported in other studies (Martin & Thomas 2011, Watzlawick et al 2014). Moreover, a large within-family variations in C content was observed.…”

Reliable calculations of carbon stocks in forest ecosystems are crucial for proper implementation of global warming mitigation policies. Accurate estimations depend upon applying the correct factor of carbon (C) concentration for different forest species and tissues instead of the often assumed 50% carbon content. Despite the high forest species richness in Mexico and the increasing CO2 emissions, data on carbon concentrations in forest plant tissues are scarce. In this study, we determined variation in C concentration of different tissues for 175 plant species common in Mexican forests. C contents were estimated and contrasted for plant distribution, taxa, and plant structure (main stems, branches, twigs, bark, leaves, buds, fruits, roots and root cuticles). The mean C concentration across species was 44.7%. Species significantly differed in C concentration by tissue, environment and taxa. These multi-species data contribute to improve precision on estimates of C balance in terrestrial ecosystems, reducing the uncertainty in C inventories in Mexico and elsewhere.

“…The results of this study show that the levels of C varied between 451.4 and 456.8 g kg -1 in the organs of the different species evaluated. This is consistent with the results of previous studies in the Atlantic Forest (MELLO CUNHA et al 2009;VIEIRA et al, 2011;WATZLAWICK et al, 2012;WATZLAWICK et al, 2014).…”

The objective is to quantify the carbon content (C) of the reservoirs of plant biomass of different species in a fragment of the Atlantic Forest in Northeast Brazil. Ten species of high absolute density were selected. We sampled biomass from the leaf and wood compartments of each species to determine the C content. There was a difference in leaf C levels between species. The C content in leaves of species varied between 451.4 and 456.7 g kg-1. The C content of the wood of species varied between 451.7 and 456.8 g kg-1. The group formed by the families Burseraceae, Moraceae, and Sapotaceae showed higher average levels of C in leaves. The Burseraceae family had the highest average C content in the species' wood. The use of a pre-established carbon content (500 g kg-1) may generate inconsistent estimates higher than the real values for the species and families in an Atlantic Forest environment. We suggest that C stock estimates use specific levels for species and/or families, contributing to a more realistic estimate of C storage patterns in the shoot biomass of Atlantic Forest species.Keywords: Carbon concentration; Carbon sequestration; Tropical Rainforest.

“…As florestas proporcionam diversos serviços ambientais, sendo um deles os elevados estoques de biomassa e carbono (SANQUETTA et al, 2011;STINSON et al, 2011;WATZLAWICK et al, 2014). A fixação de carbono ocorre na biomassa vegetal e está diretamente relacionado às mudanças Sci.…”

O presente estudo teve por objetivo estimar e estratificar o estoque de biomassa em dois sistemas de manejo, sendo o primeiro um fragmento de Floresta Ombrófila Mista Secundária (FOMS) e o segundo um fragmento de Floresta Ombrófila Mista em Sistema Silvipastoril (FOMSP), correlacionado com a florística e a dinâmica da biomassa no período de 2013 e 2016, no município de Turvo, PR. Os dados foram obtidos de duas parcelas permanentes, sendo de 1,8 hectares em área com FOMSP e 1,68 hectares em área de FOMS, subdivididas em subparcelas contíguas de 100 m 2 , em cada área. A biomassa estimada foi calculada por meio da estratificação dos compartimentos (fuste, casca, galhos e folhagem), utilizando-se os dados de DAP (Diâmetro à Altura do Peito). As áreas abrangem 32 famílias botânicas, 56 gêneros e 76 espécies. No que se refere à biomassa total, verificou-se que na FOMS foi superior a encontrada na
