An epidemiological model of viral infections in a Varroa-infested bee colony: the case of a bee-dependent mite population size [PDF]
arXiv, 2016 In recent years the spread of the ectoparasitic mite Varroa destructor has become the most serious threat to worldwide apiculture. In the model presented here we extend the bee population dynamics with mite viral epidemiology examined in an earlier paper by allowing a bee-dependent mite population size.

Angewandte Chemie, EarlyView.Wir präsentieren eine metallfreie Methode für die Deuteriummarkierung von Aromaten in deuteriertem HFIP. Dieser Ansatz nutzt die erhöhte Basizität von Aromaten im angeregten Zustand, um den selektiven Wasserstoffisotopenaustausch an schwer zugänglichen Positionen zu ermöglichen.

The carnivorous plant Genlisea harnesses active particle dynamics to prey on microfauna [PDF]
arXiv, 2023 Carnivory in plants is an unusual trait that has arisen multiple times, independently, throughout evolutionary history. Plants in the genus Genlisea are carnivorous, and feed on microorganisms that live in soil using modified subterranean leaf structures (rhizophylls).

Angewandte Chemie, EarlyView.Ein kleiner, aber entscheidender Unterschied: Typ‐III‐Kupferenzyme, wie Tyrosinasen (TYRs) und o‐Aminophenoloxidasen (AOs), katalysieren die Oxidation von o‐Aminophenolen (AP) zu Chinoniminen. Im Gegensatz zu TYRs können AOs AP weiter zu Nitrosophenolen oxidieren.

Viral epidemiology of the adult Apis Mellifera infested by the Varroa destructor mite [PDF]
arXiv, 2015 The ectoparasitic mite Varroa destructor has become one of the major worldwide threats for apiculture. Varroa destructor attacks the honey bee Apis mellifera weakening its host by sucking hemolymph. However, the damage to bee colonies is not strictly related to the parasitic action of the mite but it derives, above all, from its action as vector ...
