Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change. [PDF]

Glob Chang Biol
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Mapping the density of giant trees in the Amazon. [PDF]

New Phytol
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Satellite assessment of winter cover crop and conservation tillage outcomes to support adaptive management in working landscapes. [PDF]

J Environ Qual
Abstract The use of winter cover crops and conservation tillage are agricultural practices promoted to reduce nutrient and sediment loss from cropland, improve soil health, increase infiltration, and support farm nutrient cycling and ecosystem services. However, environmental performance of these practices is variable in the working farm landscape. The

PIROLISIS BIOMASSA: REVIEW

Agroindustrial Technology Journal, 2022
The exploitation of fossil energy causes non-renewable reserves to dwindle and causes global warming; climate change endangers living things. Energy sources from the second generation, namely lignocellulosic-based biomass, provide development opportunities, not interfere with food reserves, and are easy to cultivate.
