An OU-led study sheds new insight on forest loss and degradation in Brazilian Amazon

"...Tropical forests in the Amazon account, Qin notes, for approximately 50% of the rainforests in the world and are important for global biodiversity, hydrology, climate and the carbon cycle. Accurate and timely data on vegetation aboveground biomass and forest area in the region at various spatial and temporal scales are also essential for data-based policies and decision making. This international team harnessed diverse data for monitoring, reporting and verification of tropical forests..."

Mountain high: Andean forests have high potential to store carbon under climate change

"..."The amount of carbon that is stored in the aboveground biomass in the stems and leaves of trees is actually increasing through time, potentially offsetting some of the carbon dioxide emissions that are released to the atmosphere," said Tello, an associate scientist at the Center for Conservation and Sustainable Development at the Missouri Botanical Garden..."

Introducing the Plant Phenomics & Precision Agriculture Collection

"...Several papers in the Collection focus on the potential of unmanned aerial vehicles (UAVs) for phenotyping and surveillance of crop status. In their study, Grüner and colleagues tested whether UAV-based multispectral and textural monitoring could predict aboveground biomass and nitrogen fixation in grass-legume mixtures [9]. Their results showed great promise for this approach, with strong evidence for the importance of including textural information in prediction models..."

The biggest trees capture the most carbon: Large trees dominate carbon storage in forests

"...Older, large-diameter trees have been shown to store disproportionally massive amounts of carbon compared to smaller trees, highlighting their importance in mitigating climate change, according to a new study in 21 inches or >53. 3 cm) on National Forest lands within Oregon and Washington. They found that despite only accounting for 3% of the total number of trees on the studied plots, large trees stored 42% of the total above-ground carbon within these forest ecosystems..."

Cover crop roots are an essential key to understanding ecosystem services

"...To judge the overall effectiveness of cover crops and choose those offering the most ecosystem services, agricultural scientists must consider the plants' roots as well as above-ground biomass, according to Penn State researchers who tested the characteristics of cover crop roots in three monocultures and one mixture..."

Lightning strikes more than 100 million times per year in the tropics

"...Forests that experience more lightning strikes each year have fewer large trees per hectare, perhaps because the large individual trees in these forests stand out more, higher rates of woody biomass turnover (more tree biomass dies each year) and less total aboveground biomass. But more burning questions remain. No one knows why some trees survive lightning strikes while others die, although it is likely that trees have evolved ways of coping with such a common threat..."
