News leads from the USDA FS Southern Research Station
The following are leads for stories on ongoing Forest Service research to restore habitat for the Louisiana pine snake, red-cockaded woodpecker, cerulean warbler, Indiana bat, American eel, and North American freshwater mussels.
Louisiana Pine Snake – Louisiana pine snake, a species of conservation concern, is associated with the longleaf pine forests of the West Gulf Coastal Plain. Craig Rudolph uses radiotelemetry and other methods to study this elusive snake, which many experts believe to be the rarest vertebrate in the United States. Louisiana pine snakes prey mainly on pocket gophers, using their burrows to hibernate. Alteration of the fire regime in the longleaf pine ecosystem in the West Gulf Coastal Plain has led to a decline in the plants that support the pocket gopher, which in turn has led to population declines of the Louisiana pine snake. Roads have also had a significant effect. Habitats are fragmented, and large numbers of snakes are killed by vehicles: data from a recent study suggests that impacts may extend several hundred meters from the road itself.

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
