In a multiple-choice test, the preference of egg-laying Polygonia c-album (comma butterfly) females was studied for oviposition on plants bearing surrogate leaves treated with crude methanol extracts obtained from leaves of seven host-plant species: Humulus lupulus, Urtica dioica, Ulmus glabra, Salix caprea, Ribes nigrum, Corylus avellana, and Betula pubescens. The ranking order of surrogate le...

Campylobacter jejuni NCTC12662 has been the choice bacteriophage isolation strain due to its susceptibility to C. jejuni bacteriophages. This trait makes it a good candidate for studying bacteriophage-host interactions. We report here the whole-genome sequence of NCTC12662, allowing future elucidation of the molecular mechanisms of phage-host interactions in C. jejuni.

To examine the mediation of host–predator interaction by a parasite, we studied the three-level interactions among a host plant, a root hemiparasitic plant, and their common predator, a generalist snail herbivore. The host species, Trifolium repens, is able to synthesize cyanogenic glucosides that have a significant role in plant herbivore resistance. Some T. repens populations are polymorphic ...
