Woodpeckers: There’s a fungus among us

11.02.2004


Woodpeckers carry fungus in beaks that promotes tree decay



A new study in the journal Condor by the New York-based Wildlife Conservation Society (WCS) and Arkansas State University suggests that a woodpecker’s beak is a virtual petri dish of fungal spores that play a key role in the decay of dead trees, or "snags."

The authors examined several species of woodpeckers living in ponderosa pine forests in northern California and Oregon, finding that over 60 percent of the sampled birds nesting in tree cavities had a variety of wood-inhabiting fungi living in their beaks.


These fungi serve a critical role in the decomposition of dead trees and influence how they are used by wildlife. Without adequate decay, woodpeckers are unable to excavate nest cavities – vital components of forests that serve as nesting sites to a variety of wildlife.

"Our study shows that woodpeckers are really the architects and landlords of the forest," said WCS scientist Kerry Farris, the study’s lead author. "Their activities play a key role in how snags decay and are used by other species."

Woodpeckers initially puncture dead and dying trees in search of bark beetles and other wood-boring insects, a process that creates holes in wood that serve as infection sites for airborne fungal spores. As the birds return to these holes to feed, or to excavate them further for nesting, they pick up the fungi in their beaks, then help spread the spores by foraging on other dead trees.

While some forestry practices on public and private lands allocate a certain number of snags per acre for wildlife use, some recent federal policies call for removing snags because of their perceived risk in forest fires. The authors say that more factors need to be taken into consideration than just density or spatial arrangement of snags.

"Our research illustrates the numerous agents contributing to the complexity of snag decomposition and eventual cavity generation by woodpeckers," Farris said. "Forest management could benefit from a consideration of these processes when managing snags on public and private lands."

Im Focus: Fraunhofer IDMT demonstrates its method for acoustic quality inspection at »Sensor+Test 2019« in Nürnberg

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.

Reducing machine downtime, manufacturing defects, and excessive scrap

Im Focus: Successfully Tested in Praxis: Bidirectional Sensor Technology Optimizes Laser Material Deposition

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«...

Im Focus: MPSD team discovers light-induced ferroelectricity in strontium titanate

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...
