New research unravels the dynamics of tree production, economics and variability in demand to show how to reduce the risks of importing such damaging forest pests and diseases as oak processionary moth and ash dieback.
Fishing quotas have been decided using an inadequate method for decades, according to a Scientific Reports study. The same method has also been used to decide about culling, hunting quotas, or translocating threatened species. Analysing the nuclear genome of sardines shows previously unrecognised genetic differences between populations, which are not identified by the go-to-method for Isolation-By-Distance, mitochondrial DNA analysis.
Mountain hare numbers on moorlands in the eastern Highlands have declined to less than one per cent of their initial levels, according to a newly published long-term scientific study.
New research shows that co-management approaches -- based on shared responsibility for resource management among individuals and institutions -- can build resilience to socio-environmental change by strengthening use of science in decision making and promoting adaptive capacities, such as learning and leadership.
The number of people who died as a result of Hurricane Maria -- which hit Puerto Rico on Sept. 20, 2017 -- may be as high as 1,139, surpassing the official death count of 64, according to researchers.
Industrial fishing fleets have doubled the distance they travel to fishing grounds since 1950, which means that they are now able to reach 90 percent of the global ocean, but are catching only a third of what they did 65 years ago per kilometer traveled.
A study of firefighters in the United States breaks new ground in understanding how groups of workers -- especially those in high-risk occupations -- are able to take leaps of faith. The study conveys what goes into a person's ability to make critical trust-related judgments. It also has relevance and managerial implications in an era of declining trust in both people and institutions, the study's authors said.
In addition to the diversity of tree species, the variety of animal and fungus species also has a decisive influence on the performance of forests. Forest performance comprises many facets besides timber production, such as carbon storage and climate regulation. The study is based on ten years of research in species-rich subtropical forests. A team of researchers led by iDiv and the Martin-Luther-University Halle-Wittenberg has published the results in the new issue of Nature Communications.
Feral horses living in Theodore Roosevelt National Park in the Badlands of North Dakota likely had multiple origins, but have since become inbred, according to Igor Ovchinnikov of the University of North Dakota, and colleagues, in a study published Aug. 1 in the open-access journal PLOS ONE.
Federal plans to complete a continuous wall along the US-Mexico boundary would threaten the existence of numerous plant and animal species, according to a new study.
