Deforestation in the tropics linked to a reduction in rainfall      (via sciencedaily.com) 

Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.

Clever orchard design for more nuts      (via sciencedaily.com) 

To reduce biodiversity loss in agricultural landscapes, more sustainable and environmentally friendly agricultural practices are needed. A research team has investigated how ecosystem services such as pollination could be improved in macadamia plantations. The scientists showed that a certain design of plantations -- for instance, how the rows of trees are arranged, the varieties, and the integration of semi-natural habitats in and around the plantations -- can increase the pollination performance of bees.

A fifth of California's Sierra Nevada conifer forests are stranded in habitats that have grown too warm for them      (via sciencedaily.com) 

Researchers created maps showing where warmer weather has left trees in conditions that don't suit them, making them more prone to being replaced by other species. The findings could help inform long-term wildfire and ecosystem management in these 'zombie forests.'

Researcher discovers threshold that triggers drought response in forests      (via sciencedaily.com) 

Missouri is home to an array of natural resources, with forests among the state's most valuable ecosystems. As warmer temperatures fueled by climate change affect ecosystems globally, forests are under stress to adapt to these changes and ensure their survival in a warmer world. Researchers now introduce the 'ecosystem wilting point' concept, which explains how whole forests respond to drought.

Detecting the impact of drought on plants with user-friendly and inexpensive techniques      (via sciencedaily.com) 

Climate change is aggravating the impact of droughts -- one of the factors that only affect plant physiology -- on all plant ecosystems worldwide. Although new tools have been developed to detect and assess drought stress in plants -- transcriptomic or metabolomic technologies, etc. -- they are still difficult to apply in natural ecosystems, especially in remote areas and developing countries.

Gene variations for immune and metabolic conditions have persisted in humans for more than 700,000 years      (via sciencedaily.com) 

A new study explores 'balancing selection' by analyzing thousands of modern human genomes alongside ancient hominin groups, such as Neanderthal and Denisovan genomes. The research has 'implications for understanding human diversity, the origin of diseases, and biological trade-offs that may have shaped our evolution,' says evolutionary biologists.
