What does it take for palm trees, the unofficial trademark of tropical landscapes, to expand into northern parts of the world that have long been too cold for palm trees to survive? A new study, led by Lamont-Doherty Earth Observatory researcher Tammo Reichgelt, attempts to answer this question. He and his colleagues analyzed a broad dataset to determine global palm tree distribution in relation to temperature.
Researchers at the University of British Columbia have shed new light on how mountain pine beetles produce an important pheromone called trans-verbenol, which could aid in efforts to better predict outbreaks.
The extreme wet and dry periods Mongolia has experienced in the late 20th and early 21st centuries are rare but not unprecedented and future droughts may be no worse. An international team of researchers developed a climate record stretching 2,060 years into Mongolia's past using tree rings. The team then combined the tree-ring record of past climate with computer models that can project future regional climate.
Up to half of plant and animal species in the world's most naturally rich areas, such as the Amazon and the Galapagos, could face local extinction by the turn of the century due to climate change if carbon emissions continue to rise unchecked. Even if the Paris Climate Agreement 2°C target is met, these places could lose 25 percent of their species. Researchers examined the impact of climate change on nearly 80,000 plant and animal species in 35 areas.
Researchers have discovered a rule to predict an arthropod community structure based on the genomic variation in a foundation tree species.
A recent study finds that urban trees can survive increased heat and insect pests fairly well -- unless they are thirsty. Insufficient water not only harms trees, but allows other problems to have an outsized effect on trees in urban environments.
A University of Toronto-led study shows that cattle ranching, agriculture and other human activities breaking up Costa Rican forests into isolated patchy fragments, are causing more problems for native plant populations than for monkey species sharing the same habitat.
A mix of factors is contributing to an increasing mortality rate of trees in the moist tropics, where trees in some areas are dying at about twice the rate that they were 35 years ago.
According to study, after being converted to pastures, areas of the so-called 'Cerrado' become closed forest with poor biodiversity if not appropriately managed. This biome works as the source for much of Brazil's main river basins, and boasts biodiversity levels higher than tropical forests at the microscale.
Scientists described two species of previously unknown stone centipedes from China. Now housed at the Hengshui University, China, the studied specimens were all collected in the leaf litter or under rocks in larch forests. The research is published in the open access journal ZooKeys.
