Burr Chervil: New Weed Threat Grows from a Humble Start

19.07.2004


Burr chervil is a new weed exploding across northern Idaho’s landscape. The weed may offer important clues to the biology of invasive species in general, a University of Idaho scientist says.



A decade ago, burr chervil seemed like it didn’t pose much of a threat, said Tim Prather, a UI weed scientist at Moscow. “We knew of a few plants that grew under hawthorn trees near Lewiston. It just seemed to be sitting there and not doing much.”

That was when Prather was doing graduate work at UI in the early 1990s. After completing his education and starting his career, he returned to UI as an weed science professor in 2000. Burr chervil had changed.“We would find it in places we never expected it while we were looking for other weeds,” Prather said.


Now burr chervil is spreading across wide areas of the lower Clearwater River valley from Lewiston to Lapwai in places where yellow starthistle, a major weed problem, thrives.

More alarming to Prather is that burr chervil is showing up in wetter locales as far north as Latah County north of Moscow.

The weed is a member of the carrot family and is avoided by wildlife and livestock. It is named for its small seeds that are equipped with small hooks, allowing it to easily hitch rides and spread rapidly.

Prather is excited about the potential of the new Center for Research on Invasive Species and Small Populations to help understand burr chervil’s sudden change. "We want to use the sophisticated DNA techniques to see if we can spot genetic changes that allow a population to adapt to its environment and suddenly begin to multiply,” Prather said.

One theory says invasive weeds first enter new habitats in a quiet phase. The plants reproduce for a few generations, during which their genes are effectively shuffled. Like a combination lock, the genetic “tumblers” eventually find the right sequence to fit environmental conditions and the plant multiples rapidly.

Prather wants to go back to the original site of the burr chervil infestation to study the genetic madeup of those plants, then compare it with plants found in new locations.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
