Professor unearths the ancient fossil plant history of Burnaby Mountain      (via sciencedaily.com)     Original source 

New research led by a paleobotanist provides clues about what plants existed in the Burnaby Mountain area (British Columbia, Canada) 40 million years ago during the late Eocene, when the climate was much warmer than it is today.

Oldest bat skeletons ever found described from Wyoming fossils      (via sciencedaily.com)     Original source 

Scientists have described a new species of bat based on the oldest bat skeletons ever recovered. The study on the extinct bat, which lived in Wyoming about 52 million years ago, supports the idea that bats diversified rapidly on multiple continents during this time.

Multifunctional patch offers early detection of plant diseases, other crop threats      (via sciencedaily.com)     Original source 

Researchers have developed an electronic patch that can be applied to the leaves of plants to monitor crops for different pathogens -- such as viral and fungal infections -- and stresses such as drought or salinity. In testing, the researchers found the patch was able to detect a viral infection in tomatoes more than a week before growers would be able to detect any visible symptoms of disease.

Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists      (via sciencedaily.com)     Original source 

Soil stores more carbon than plants and the atmosphere combined, and soil microbes are largely responsible for putting it there. However, the increasing frequency and severity of drought, such as those that have been impacting California, could disrupt this delicate ecosystem. Microbial ecologists warn that soil health and future greenhouse gas levels could be impacted if soil microbes adapt to drought faster than plants do.

British flower study reveals surprise about plants' sex life      (via sciencedaily.com)     Original source 

A study of Britain's native flowering plants has led to new insights into the mysterious process that allows wild plants to breed across species -- one of plants' most powerful evolutionary forces.  When wild flowering plants are sizing up others they may often end up in a marriage between close relatives rather than neighbors, a new study has revealed.

Rooting out how plants control nitrogen use      (via sciencedaily.com)     Original source 

Nitrogen is such a crucial nutrient for plants that vast quantities of nitrogen-containing fertilizers are spread on farmlands worldwide. However, excess nitrogen in the soil and in drainage run-off into lakes and rivers causes serious ecological imbalances. A recent study has uncovered the regulatory mechanisms at work when plants utilize nitrogenous fertilizers in their roots, a positive step in the quest to generate crops that require less fertilizer while still producing the yields needed to feed the world.

Scientists show how we can anticipate rather than react to extinction in mammals      (via sciencedaily.com)     Original source 

Most conservation efforts are reactive. Typically, a species must reach threatened status before action is taken to prevent extinction, such as establishing protected areas. A new study shows that we can use existing conservation data to predict which currently unthreatened species could become threatened and take proactive action to prevent their decline before it is too late.

Technology advance paves way to more realistic 3D holograms for virtual reality and more      (via sciencedaily.com)     Original source 

Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.

Insect decline also occurs in forests      (via sciencedaily.com)     Original source 

The number of insects has been declining for years. This has already been well documented for agricultural areas. In forests, however, temporal trends are mostly studied for insect species that are considered pests. Now, a research team has studied the trends of very many insect species in German forests. Contrary to what the researchers had suspected, the results showed that the majority of the studied species are declining.
