Biomass models are key to the correct quantification of aboveground biomass and carbon stocks. Most current available sets were developed for adult trees although very few have been employed accurately estimate during first years reforestations, despite increasing number reforestations over recent years. In this study, species-specific generalized single main 14 species used in Spain. A compari...

Cessation of cattle grazing has resulted in the reestablishment wetlands some streams U.S. Southwest. Decades prevented vascular plant growth Sycamore Creek (Arizona, U.S.A.), resulting stream reaches dominated by diatoms and filamentous green algae. Establishment plants can profoundly modify ecosystem processes; yet, effects on nitrogen (N) cycling remain unexplored. We examined consequences t...

Accurate estimation of small-scale forest biomass is a prerequisite and basis for trading carbon sinks optimizing the allocation forestry resources. This study aims to develop plot-scale methodology estimating aboveground (AGB) that combines horizontal distribution model (HDM) sampling techniques improve efficiency, reduce costs provide reliability biomass. Simao pine (Pinus kesiya var. langbia...

Four tree species were harvested periodically over a 13-year period from plantations in the humid lowlands of Costa Rica: Cedrela odorata, Cordia alliodora, Hyeronima alchorneoides, and Euterpe oleracea. The soil was a well-drained, volcanic alluvium, and high fertility coupled with 4 m of annual rainfall and high temperatures led to rapid growth rates; at age 13 many individual were >30 cm dbh...

BACKGROUND Hyaluronic acid is one of the biopolymers most commonly used by the pharmaceutical industry. Thus, there is an increasing number of recent works that deal with the production of microbial hyaluronic acid. Different properties and characteristics of the fermentation process have been extensively optimised; however, new carbon and protein sources obtained from by-products or cheap subs...
