Dec. 16, 2021 Researchers have investigated the genetic structure of the relic species, Acer miyabei, from three regions in Japan: Hokkaido Island and two southern groups in Northern and Central Honshu. There was ...
Dec. 13, 2022 Short-term, heavy feeding by adult spotted lanternflies on young maple trees inhibits photosynthesis, potentially impairing the tree's growth by up to 50 percent, according to a new ...
Sep. 30, 2021 A new study has found that recent bigleaf maple die-off in Washington is linked to hotter, drier summers that predispose this species to decline. These conditions essentially weaken the tree's ...
Sep. 1, 2023 In 2012, when the spotted lanternfly (Lycorma delicatula) arrived in the U.S. from its home in China, scientists, land managers, and growers were understandably concerned that the sap-feeding insect ...
May 19, 2021 An ecologist investigates pest infestation in forests with mixed and monoculture tree ...
Aug. 23, 2022 For the first time, researchers have completed threat assessments for all 881 native tree species in the contiguous United States, resulting in a comprehensive checklist and synthesis that will serve ...
Aug. 16, 2022 A new framework for classifying the positive impacts of non-native species will allow conservationists and policymakers to make better-informed management decisions, according to a new ...
Sep. 1, 2021 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 ...
Aug. 23, 2023 Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an ...
Oct. 12, 2021 In the face of declining fisheries, threatened reef habitat, and changing climatic conditions, non-native mangroves may provide, rather than impede, zooplankton habitat availability in novel ...
