The adoption of 'silvopastures' -- incorporating trees into pastureland -- can provide habitat for forest bird species and improve connectivity in landscapes fragmented by agriculture. But how do silvopastures measure up to natural forest habitat? New research shows that birds in silvopasture forage less efficiently than those in forest fragments but offers suggestions for how silvopasture habitat could be improved.
Central Africa's Albertine Rift region is a biodiversity hotspot consisting of a system of highlands that spans six countries. Recent studies have shown that the population of sooty bush-shrikes occupying the region's mid-elevation forests is a distinct species, and new research reveals that this newly discovered species may already be endangered due to pressure from agricultural development.
Researchers report that forests with trees that employ a high diversity of traits related to water use suffer less of an impact from drought. The results, which expand on previous work that looked at individual tree species' resilience based on hydraulic traits, lead to new research directions on forest resilience and inform forest managers working to rebuild forests after logging or wildfire.
Climate conditions forecast for 2050 and 2070 will be potentially lethal to species less adapted to climate variation, according to Brazilian researchers.
Europe's decision to promote the use of wood as a 'renewable fuel' will likely greatly increase Europe's greenhouse gas emissions and cause severe harm to the world's forests, according to a new paper.
The end of a 52-year internal conflict could spell trouble for the second most biodiverse country in the world. A new study outlines a sustainable path forward.
Researchers have developed an evidence-based approach to designing ex situ collections that effectively preserve a target species' genetic diversity, which can be tailored for conservation of any tree species. This will allow for efficient, targeted seed collecting efforts, including number of populations to sample, the appropriate number of seeds to collect from each tree, and best choice of populations to target in a species' range.
Peatlands are extremely effective at storing carbon, but an international study has found climate change could stop that. The group investigated how peatlands - swamps and bogs with organic rich soils - have responded to climate variability between 850 BCE and 1850 CE.
Researchers found that using bio-sequestration to capture carbon produced by US coal-fired plants even after carbon capture and storage would require using 62 percent of the nation's arable land for that process, or 89 percent of all US land with average forest cover. In comparison, offsetting the amount of carbon produced by manufacturing solar panels is 13 times less land, making it a far more viable option.
Cloud forests are not immune to very down-to-earth problems of climate change and deforestation. A 10-year study of bird populations in Cusuco National Park, Honduras, shows that the peak of bird diversity in this mountainous park is moving higher in elevation. Additional land protection, unfortunately, may not be enough to reverse the trend, driven in part by globally rising temperatures.
Researchers have succeeded in producing distribution maps for a selection of important tropical tree species in Peruvian lowland Amazonia. This was achieved by using machine learning methods that combine satellite imagery and field data. The study shows that it is possible to model tree species distributions at a spatial resolution that is fine enough to facilitate the practical management of forest resources.
Between April and August this year, Switzerland and central Europe have experienced the driest summer season since 1864. Especially the forest seems to suffer from this dry spell. A current study indicates now that native forest trees can cope much better with the drought than previously expected. It is, however, too early to give the all-clear as a consistently warmer and dryer climate might still put our native forests at risk.
New research suggests that the same factors driving the Arctic's changing climate are fueling a geological response that could play a small part in counteracting those changes' malign effects.
Biodiversity plays a significant role in forest carbon storage, but surprisingly less than previously thought, new research suggests.
Compilation of data from forest inventories and botanical collections generates a list of 3,615 tree species in wetland areas of the Amazon Basin.
Widespread tree felling in African savannas is producing at least three times as many carbon emissions as was previously thought, research suggests.
Scientists have found that non-native pine and eucalypt forests planted to supply pulp and timber mills in central Chile are contributing to the massive fires.
A new study affirms a long-held hypothesis that the presence of specialized 'natural enemies' promotes tropical biodiversity. Except when it doesn't.
Kelp forests will experience a marked change in ecosystem functioning in response to continued ocean warming and the increase of warm-water kelp species, according to a new study.
To offset CO2 emissions, China is reforesting. If a mixture of tree species instead of monocultures were planted, much more carbon could be stored. An international team has shown that species-rich forest ecosystems take up more CO2 from the atmosphere and store more carbon in biomass and soil, making them more effective against climate change.
The two largest woodpeckers in North America, the imperial woodpecker and ivory-billed woodpecker, are believed to have gone extinct during the twentieth century. Can their surviving cousin, the pileated woodpecker, persist when standing dead trees and other crucial resources are lost to urbanization? A new study tracked birds in suburban Seattle and found that as long as tree cover remains above a certain threshold, pileated woodpeckers and housing developments can coexist.
Trees growing in temperate forests in the eastern US show strong adaptation or acclimation to local climate. So reports a new study that analyzed more than 23,000 tree cores to investigate how adult trees respond to changes in climatic conditions.
New study finds volatile gases emitted by forests increase the amount of diffuse light reaching the forests. The study shows that this increased diffuse sunlight enhanced the carbon absorbed by the world's forests by an amount equal to 10 percent of global fossil fuel emissions and industry emissions.
Deforestation is suspected to have contributed to the mysterious collapse of Mayan civilization more than 1,000 years ago. A new study shows that the forest-clearing also decimated carbon reservoirs in the tropical soils of the Yucatan peninsula region long after ancient cities were abandoned and the forests grew back.
A new study tackles an important, unresolved question in the biology of invasive plants. Which is most important to the establishment of new invasive communities -- proximity to seed sources, canopy disturbance, or soil disturbance?
