Este estudo teve como objetivo quantificar a biomassa acima do solo e o conteúdo de macronutientes de duas espécies arbóreas (Myrsine ferruginea e Myrsine umbellata) da Floresta Ombrófila Mista Montana. Os dados foram coletados em 10 árvores de M. ferruginea e 9 árvores de M. umbellata, extraídas de 20 parcelas de 12 m x 12 m. A maior produção de biomassa total e de cada componente foi verificada em M. ferruginea, exceto a produção de folhas que foi maior em M. umbellata; os maiores conteúdos de macronutrientes na biomassa total também foram verificados em M. ferruginea.

Abstract Background: Studies on the relationships between biodiversity and ecosystem productivity have suggested that species richness and functional diversity are the main drivers of ecosystem processes. There is no general pattern regarding the relationship found in various studies, and positive, unimodal, negative, and neutral relationships keep the issue controversial. In this study, taxonomic diversity vs functional diversity as drivers of above-ground biomass were compared, and the mechanisms that influence biomass production were investigated by testing the complementarity and the mass-ratio hypoteses.Methods: Using data from 414 permanent sampling plots, covering 23% of temperate forests in the Sierra Madre Occiental (Mexico), we estimated the above-ground biomass (AGB) for trees ≥7.5 cm d.b.h. in managed and unmanaged stands. We evaluated AGB-diversity relationships (species richness, Shannon-Wiener and Simpson indices), AGB-weighted mean community values ​​(CWM) of tree species functional traits (maximum height, leaf size, and wood density) and five measures of functional diversity (functional dispersion, functional richness, functional uniformity, functional diversity, and RaoQ index).Results: We reveal a consistent hump-shaped relationship between aboveground biomass and species richness in managen and unmanaged forest. CWM_Hmax was the most important predictor of AGB in both managed and unmanaged stands, which suggests that the mechanism that explains the above-ground biomass in these ecosystems is dominated by certain highly productive species in accordance of the mass-ratio hypothesis. There were no significant relationships between taxonomic diversity metrics (Shannon-Wiener and Simpson indices) or measures of functional diversity with AGB. The results support the mass-ratio hypothesis to explain the AGB variations.Conclusions: We concluded that diversity does not influence biomass production in the temperate mixed-species and uneven-aged forests of northern Mexico. These forests showed the classic hump-shaped productivity-species richness relationship, with biomass accumulation increasing at low to intermediate levels of species plant diversity and decreasing at high species richness. Functional diversity explains better forest productivity than classical diversity metrics.

Halli lepa, hübriidlepa ja arukase biomassi produktsioon endistel põllumaadel The present study is based on four experimental sites, located in Southern-Estonia: hybrid alder and grey alder plantations located in Põlva county, and two sample plots of silver birch, located in Tartu county. The stand characteristics, above-ground biomass and current annual production (CAP) were estimated in order to evaluate production capacity of different tree species growing on abandoned agricultural lands. Due to fast growth and high biomass production capacity the most promising tree species for short-rotation forestry in Estonia is grey alder. The stem mass in the 13-years-old grey alder and hybrid alder stand was 63.4 t ha-1 and 40.0 t ha-1, respectively. However, the different biomass production is mainly affected by stand densities, 6170 trees per ha and 4080 trees per ha, respectively. During ageing, the differences between the alder stands diminish. At the age of 14, mean height and diameter at breast height were practically equal. Also the mean stem mass in the older, 13-year old stand, is almost equal: 10.3 kg in grey alder stand and 9.8 kg in hybrid alder stand. At a younger age, the mean stem mass was higher in grey alder stand, but later, at the age of 13, the mean stem mass has become almost the same (10.3 kg in grey alder stand and 9.8 kg in hybrid alder stand). The rotation period for hybrid alder is longer than for grey alder and bulk maturity will occur later. Silver birch is also a highly productive tree species and has a prospect for short-rotation forestry. The mean stem mass and annual current increment of 8-year-old silver birch stand was in same the magnitude as in the grey alder stand. Although the average stand diameter and height were lower in the silver birch stand than in the grey alder stand, it is compensated by the higher wood density of birch wood. The number of trees has affected silver birch stand production, the above-ground biomass in the very high density birch stand (35 600 trees per ha) was significantly lower than in the sparse stand (11 600 trees per ha), 22.8 t ha-1 and 31.2 t ha-1, respectively.

Drought represents one of the major factors limiting productivity of managed and natural ecosystems. Under natural field conditions drought is often associated with other stress factors such as high temperature and UV radiation, which may result in enhancement or vice versa alleviation of drought impact. Remote sensing methods have a large potential to evaluate impacts of drought on plant production at regional scale. The main objective of this study was to analyse the potential of ground-based measurement of spectral reflectance and thermal imaging for monitoring the impacts of drought and UV radiation on above-ground biomass production of mountain grassland ecosystem. Experimental rain-out shelters were used to manipulate incident precipitation and UV radiation for 7 weeks (May–July). A canopy spectral reflectance, thermal images, and total above-ground biomass were determined at the end of drought and UV treatment. Results show that drought led to a significant reduction of above-ground biomass, particularly under ambient UV radiation. In contrary, UV had only negligible effect on biomass production. Canopy temperature as well as selected spectral reflectance indices showed significant response to drought stress and also significant relationships to above-ground biomass. However, the relationship between canopy temperature and above-ground biomass is modified by UV radiation. Best prediction of changes in biomass caused by drought stress was provided by vegetation index NDVI.
