Therapeutic Bark Gouging as an Effective Complement for the Management of Ips typographus and Pityogenes chalcographus While Preserving Habitat for Secondary Scolytine (Coleoptera: Curculionidae) Species

Journal of Applied Entomology, EarlyView.
ABSTRACT Norway spruce will likely remain an important tree species in Europe over the next few decades despite efforts to transform forests and reduce its distribution range more to its natural range. Consequently, Ips typographus will remain one of the most relevant forest pests the management of which will become increasingly challenging due to ...

Associations of Adiposity With Gut Microbiota Composition Among Adults—Results From a Federated Analysis of Individual Participant Data From Eight European Observational Studies

Obesity Reviews, EarlyView.
ABSTRACT Gut microbiota may contribute to the adiposity‐associated disease risk, but human studies reported inconsistent associations of adiposity with gut microbiota composition. We examined associations of body mass index (BMI) with alpha diversity and relative microbial abundance at the phylum and genus taxonomic levels (based on 16S rRNA amplicon ...

Genetic and environmental regulation of arbuscular mycorrhizal responsiveness in petunia: Implications for breeding and trait selection

Plant Biology, EarlyView.
Arbuscular mycorrhiza responsiveness varies strongly among Petunia species and RILs, representing a genetically determined trait with breeding potential that is nonetheless strongly modulated by environmental conditions. Abstract Arbuscular mycorrhizal (AM) fungi enhance plant nutrition and stress tolerance, yet their agricultural use remains limited ...
