Condition-dependent ejaculate size and composition in a ladybird beetle [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2010 Sexually selected male ejaculate traits are expected to depend on the resource state of males. Theory predicts that males in good condition will produce larger ejaculates, but that ejaculate composition will depend on the relative production costs of ejaculate components and the risk of sperm competition experienced by low- and high ...

Area‐restricted search under realistic constraints
Oikos, EarlyView.Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Ladybird Beetles and Aphid Control [PDF]
, 1949 The author discusses Ladybird beetles long recognized as beneficial insects which largely feed largely upon aphids. An examination on June 24 of a late seeding of wheat, infested with greenbugs, (aphids) near Fargo showed ladybird beetles to be present

The conservation of saproxylic beetles in boreal forest [PDF]
, 2006 Forest management has altered the age structure, tree species composition and dead wood availability of Swedish boreal forests. As a consequence, many saproxylic (wood living) insect species have decreased in abundance and many species are threatened ...

Take flight: predation risk induces wing polyphenism and dispersal in the aphid Myzus persicae
Pest Management Science, EarlyView.Predator risk above a critical density induces winged morphs in Myzus persicae, promoting dispersal and reducing predation compared with wingless aphids. This density‐dependent phenotypic plasticity enhances survival but may compromise biological control by facilitating aphid dispersal.
