Forty years after Dan Luoma found an unsual truffle collection, scientists confirmed it is a new species and named it after Luoma.
A long-term study on cycads in Guam has revealed how rapidly invasive species devastated the native Cycas micronesica species and the key factors that have influenced the plant's mortality. The research -- conducted by the Western Pacific Tropical Research Center at the University of Guam and the College of Micronesia-FSM -- is published in the May 2020 issue of Diversity, a peer-reviewed journal published by MDPI.

Climate change in eastern Australia will shift when hazard reduction burning occurs but for most areas the number of suitable days remains unchanged. In some places, there will even be increases. Queensland is the only exception where the window for hazard reduction burning declines. However, climate change also increases the frequency and intensity of inversion layers, meaning it is more likely atmospheric conditions will concentrate smoke and particulate matter close to the ground.
Various forms of mercury are released naturally by volcanoes and weathering of rocks and soil. Human activities, such as mining or burning fossil fuels, can also release the element into the environment, where aquatic microbes can convert it into the toxic form, methylmercury. Now, researchers reporting in ACS' Environmental Science & Technology have shown that dragonfly larvae, collected from national parks as part of a citizen-scientist engagement program, can serve as sentinels for mercury bioaccumulation.
Whether they travel only a few metres or tens of kilometres to a new host tree, female pine beetles use different strategies to find success--with major negative consequences for pine trees, according to new research by University of Alberta biologists.
Groundbreaking study first to identify Brazil's 'bad apple' beef and soy producers, illegally chopping down forests to feed Europe's appetite; Researchers show that transparent data and science-based monitoring are the most potent weapons against illicit forest loss
The need to cover an open wound on cycad stem cuttings has been confirmed by the Western Pacific Tropical Research Center at the University of Guam in a study published in the Tropical Conservation Science journal on April 27. And the scientists have shown that the list of products that effectively fulfill this purpose is not restrictive.
In a surprise twist, a major group of flowering plants is evolving twice as quickly in temperate zones as the tropics.
Characteristics of palm trees differ from those of other tropical trees in many ways. In a major new study led by scientists at Uppsala University, Sweden, and University of Campinas, Brazil, they have surveyed the actual numbers of palms in tropical rainforests around the globe. The proportion of palm trees is important to include in calculations of forests' potential carbon storage and in estimates of forested areas' sensitivity to climate change.
