Gene that promotes woody stem growth helps prevent dehydration in plants.

Preventing the re-clearing of second-growth forests is a major challenge for restoration efforts in tropical regions, according to a new study led by international researchers. The study found that a third of regenerating areas in the Brazilian Atlantic Forest were cut down again, most after just 4 to 8 years of regeneration.
Tropical forests are disappearing at an alarming rate through deforestation, but they also have the potential to regrow naturally on abandoned lands. This has been shown by an international study led by scientists from Wageningen University. How a forest recovers, depends on the amount of rainfall, the age of the forest, and the functional characteristics of the tree species.
With commitments to restore more than 47.5 million hectares of degraded land and forests by 2030, the Philippines, Indonesia, Malaysia and India hope to become exemplar land custodians. While commitments ending deforestation are critical to obtaining that image—Indonesia is one of the world’s poster children for forest loss—even a full halt to natural landscape destruction is only part of the battle to fight climate change and restore myriad ecosystem services, which the United Nations Food and Agriculture Organization simply states, “make human life possible.”
As forests age, differences in species functional traits become more important and reliable in predicting forest productivity, according to an international study.
In a study published recently, researchers have revealed that a tropical rainforest tree species underwent a recent and rapid population expansion in Borneo, showing that an understanding of a species’ past is important for ensuring its future.
Tree DNA has revealed how African rainforests responded to past climate change including ice ages, new research shows. The new study found clues to support this, by identifying genetic signs of points when two populations of the same species emerged from one ancestral population – probably caused by the forest fragmenting into separate sections.
Mature oak trees will increase their rate of photosynthesis by up to a third in response to the raised CO2 levels expected to be the world average by about 2050, new research shows.
Today’s cities don’t have walls for protection like ancient ones, but they are separate from less urban and rural land. Most goods that city-dwellers purchase are brought in from rural farms and manufacturers. There is an active community of urban gardeners and landscape architects who are trying to bring more of the “country” back into the city. And for good reason. Urban landscapes combining trees and crops – urban agroforestry – can offer ecological, cultural, economic benefits and more.
Invasive shrubs in Northeastern forests that sprout leaves earlier in the spring and keep them longer in the fall not only absorb more sunlight than native shrubs, but their foliage lowers air temperatures on the forest floor, likely giving them another competitive advantage.
