Journal ArticleDOI
The diversity and phylogeography of cynipid gallwasps (Hymenoptera: Cynipidae) of the Oriental and eastern Palearctic regions, and their associated communities
TL;DR: This work summarizes what is known for all gallwasp tribes in the region extending from Pakistan to Japan and south to Indonesia, and highlights contributions that work in this region has made to understand the biology of this group as a whole.
Journal ArticleDOI
Host niches and defensive extended phenotypes structure parasitoid wasp communities
Richard G Bailey,Karsten Schönrogge,James M. Cook,James M. Cook,George Melika,György Csóka,Csaba Thuróczy,Graham N. Stone +7 more
TL;DR: The impact of host traits and phylogenetic relatedness on 48 ecologically closed and species-rich communities of parasitoids attacking gall-inducing wasps on oaks is examined and the “Enemy Hypothesis” is tested, which predicts that galls with similar morphology will exclude similar sets of Parasitoids and therefore have similar parasitoid communities.
Journal ArticleDOI
Extreme Host Plant Conservatism During at Least 20 Million Years of Host Plant Pursuit by Oak Gallwasps
Graham N. Stone,Antonio Hernández-López,James A. Nicholls,Erica di Pierro,Juli Pujade-Villar,George Melika,James M. Cook,James M. Cook +7 more
TL;DR: It appears that the coevolutionary demands of gall induction constrain host plant shifts, both in cases of mutualism (e.g., fig wasps, yucca moths) and parasitism (oak gallwasps).
Book ChapterDOI
Parasitoid recruitment to the globally invasive chestnut gall wasp Dryocosmus kuriphilus
Alexandra Aebi,Karsten Schönrogge,George Melika,Alberto Alma,Giovanni Bosio,Ambra Quacchia,Luca Picciau,Yoshihisa Abe,Seichii Moriya,Kaori Yara,Gabrijel Seljak,Graham N. Stone +11 more
TL;DR: The first overview of the natural enemies associated with D. kuriphilus in its native and invaded ranges is provided, and general patterns in community development are discussed, to predict possible future developments for the chestnut gall wasp.
Journal ArticleDOI
Reconstructing community assembly in time and space reveals enemy escape in a Western Palearctic insect community.
Graham N. Stone,Konrad Lohse,James A. Nicholls,Pablo Fuentes-Utrilla,Frazer Sinclair,Karsten Schönrogge,György Csóka,George Melika,José Luis Nieves-Aldrey,Juli Pujade-Villar,Majide Tavakoli,Richard R. Askew,Michael J. Hickerson,Michael J. Hickerson +13 more
TL;DR: Reintegration of parasitoids after host escape shows these communities to have been unsaturated throughout their history, arguing against major roles for parasitoid niche evolution or competition during community assembly.
