The changing use of the ovipositor in host shifts by ichneumonid ectoparasitoids of spiders (Hymenoptera, Ichneumonidae, Pimplinae) [PDF]

open access: yesParasite, 2018
Accurate egg placement into or onto a living host is an essential ability for many parasitoids, and changes in associated phenotypes, such as ovipositor morphology and behaviour, correlate with significant host shifts.

DNA barcoding resolves quantitative multi‐trophic interaction networks and reveals pest species in trap nests

open access: yesInsect Conservation and Diversity, Volume 16, Issue 5, Page 725-731, September 2023., 2023
Trap nests are a standardised tool so far used for monitoring bees, wasps and their interacting antagonists. With DNA‐barcoding, we now have quantified three‐trophic interaction networks, including antagonists and food resources. Food resources in wasp brood cells revealed so far unknown food species, including crop and forest pests. Construction of up

Determinism and stochasticity in the spatial–temporal continuum of ecological communities: the case of tropical mountains

open access: yesEcography, Volume 44, Issue 9, Page 1391-1402, September 2021., 2021
Ecological communities are assembled in a spatial–temporal continuum. However, we still have a poor understanding of the relative importance of different mechanisms structuring community composition (i.e. beta‐diversity) in space and time. In this study, we start by introducing a conceptual model that capitalizes upon the core‐occasional species ...
