Vælg den rigtige type feromonfælde til viklere
Viklere er en alvorlig skadevolder i danske æbleplantager. Optimal bekæmpelse kræver kendskab til flyvetidspunktet. Dette tidspunkt kan findes ved at bruge feromonfælder. Ved bestilling af feromonfælder til viklere, er det i Danmark kun muligt at få kombinationsfælder, dvs. fælder, som kan tiltrække flere arter af viklere (fælder til æblevikleren kan dog købes som enkeltfælde). En undersøgelse udført i 1999 belyser effektiviteten af kombinationsfælder. Kombinationsfælderne fanger ikke så mange viklere som enkelt fælder

Fleshy Fruits in Liliflorous Monocots
Fleshy fruits occur in several monocot orders and families, and it is generally assumed that they have been derived from capsular fruits many times during the evolution of monocot lineages. Huber hypothesized in 1969 that most capsules in Asparagales are derived secondarily from berries and that this transformation was correlated with the evolution of phytomelan-coated seeds, a pivotal character in his circumscription of Asparagales as part of reclassifying Liliaceae s.l. Dahlgren and co-workers suggested several parallel derivations and reversals in this character, e.g., the transformation sequence trifollicular fruits → capsules → berries→ capsules→ berries. Mapping of fleshy fruits on a phylogeny based on molecular characters indicates that Asparagales do not have fleshy fruits as a basal character. Dahlgren\u27s cyclic character evolution hypothesis is not supported by the distribution of dry and fleshy fruits, and there is no obvious correlation between baccate fruits and phytomelaniferous seeds in Asparagales. Phytomelaniferous seeds are not an evident synapomorphy of Asparagales as presently circumscribed. The anatomy and development of different capsular and baccate fruits in selected genera are studied in an ongoing project to reveal homologies and establish an adequate fruit typology. Some observations of texture and dehiscence structures in dry and fleshy capsules and in typical berries from hypogynous and epigynous flowers are reported in this paper

Changes in knee joint load indices from before to 12 months after arthroscopic partial meniscectomy:a prospective cohort study
Patients undergoing arthroscopic partial meniscectomy (APM) are at increased risk of knee osteoarthritis (OA). Meniscal damage and/or surgery may alter knee joint loading to increase OA risk. We investigated changes in knee joint loading following medial APM surgery, compared with the contra-lateral leg
