Semi-natural habitats help keep pests and weeds in check

Conserving semi-natural habitats such as forests, hedges and semi-natural permanent grasslands can be beneficial to the natural enemies of crop pests and weeds, and thus help farmers indirectly. A large international consortium involving INRA researchers (1) has shown that when it comes to landscape composition and the affect it has on the natural regulation of pests and predators, responses vary widely. The studies also showed that landscape alone is not in itself an efficient means to regulate crop pests.

A unique database providing information to quantify the adaptive capacity of beech to climate change

Researchers at INRA and the University of Helsinki1 have worked together to release a unique database to the scientific community2. Assembling data collected under the auspices of an EU Cost Action, the database BeechCOSTe52 gathers over 860,000 measurements of phenotypic traits. These data, from more than 500,000 beech trees growing in plantations located in 38 European countries, cover the entire range of beech’s distribution. Over 15 years of work have gone into producing the database; a vital resource for analyzing and understanding the beech’s adaptive capacity to climate change and the potential effects of climate on its distribution range.
