Deer, bears, gibbons, but especially elephants, play an important role in seed dispersal for a large-fruited tree in the forests of Thailand, according to a new study publishing July 18 in the open-access journal PLOS ONE by Kim McConkey of the National Institute of Advanced Studies in Bangalore and colleagues from BIOTEC, Thailand. The data illustrate the complexity of forest ecology and hint that, at least for this one species, changes have occurred that have diminished its overall reproductive success.
A long-term plan to preserve the Rimatara lorikeet by restoring an extirpated population of the species on a neighboring island that is free of predatory ship rats is demonstrating the importance of this kind of protective program for the sustainability of endangered bird species. A case study published in the International Union for Conservation of Nature (IUCN) report Global Reintroduction Perspectives: 2018--Case Studies from Around the Globe sums up the results of an effort that began in 2000.
Particulate matter deposits on leaves increase plant transpiration and the risk of plants suffering from drought. Particulate matter could thus be contributing more strongly to tree mortality and forest decline than previously assumed. This is suggested by results from a greenhouse study led by the university of Bonn, in which tree seedlings grown in almost particulate matter free air or in unfiltered air were compared. The results are now being published in "Environmental Research Letters".
Researchers have calculated the capacity of North American forests to sequester carbon in a detailed analysis that for the first time integrates natural processes and climate changes that are likely to alter growth over the next 60 years.
A study from the University of California, Davis, found that increased drought and wildfire risk make grasslands and rangelands a more reliable carbon sink than trees in 21st century California. As such, the study indicates they should be given opportunities in the state's cap-and-and trade market, which is designed to reduce California's greenhouse gas emissions to 40 percent below 1990 levels by 2030.
A new report from researchers from IIASA, Luleå University of Technology, and RISE Research Institutes of Sweden has shown that more biorefineries, which produce biobased fuels and chemicals, will have only a small effect on the availability and pricing of wood products and feedstocks.
The koala genome has been sequenced in a world first, by an international consortium led by Australian conservation scientists and geneticists. Considered to be the most complete marsupial genome sequenced in terms of quality -- on par with the human genome -- the highly accurate genomic data will provide information to inform habitat conservation, tackle diseases and help ensure this iconic animal's long-term survival.
In a recently published study in the journal Conservation Letters, a team of scientists reports results of a large-scale study examining giant panda habitat use trends and changing threats to their survival. This benchmark study is based on nearly 70,000 person-hours of survey work by China's State Forestry Administration throughout the panda's range in Sichuan, covering three-quarters of the entire species range.
A recent University of Montana study suggests that a warming climate in the Pacific Northwest would lessen the capacity of many forest microclimates to moderate climate extremes in the future.
A new study determined the habitat requirements for flying squirrels and compared them to those included in the recently amended Forest Act. The main finding was that the Finnish Nature Conservation Act does not adequately protect the old growth forests where flying squirrels live.
