Labandeira Ciencias de la Tierra Plant insect record Insects Land plants Vascular-plant hosts, their arthropod herbivores, and associated functional feeding groups are distributed spatiotemporallyinto four major herbivore expansions during the past 420 m.y. They are: (1) a Late Silurian toLate Devonian (60 m.y.) phase of myriapod and apterygote, hexapod (perhaps pterygote) herbivores on severalclades of primitive vascular-plant hosts and a prototaxalean fungus; (2) a Late Mississippian to end-Permian (85m.y.) phase of mites and apterygote and basal pterygote herbivores on pteridophyte and basal gymnospermousplant hosts; (3) a Middle Triassic to Recent (245 m.y.) phase of mites, orthopteroids (in the broadest sense) andhemipteroid and basal holometabolan herbivores on pteridophyte and gymnospermous plant hosts; and (4) amid Early Cretaceous to Recent (115 m.y.) phase of modern-aspect orthopteroids and derived hemipteroid andholometabolous herbivores on angiospermous plant hosts. These host-plant and herbivore associations are mediatedby seven functional feeding groups: a) external foliage feeding, b) piercing-and-sucking, c) boring (Phase 1origins); d) galling, e) seed predation, f) nonfeeding oviposition (Phase 2 origins); and leaf mining (early Phase3 origin). Within about 20 m.y. of each herbivore expansion, there is a biota that expresses the nearly full spectrumof later plant-arthropod associations. These four associational phases may be linked to the paleoclimatologicvariables of greenhouse/icehouse cycles and atmospheric O2 and CO2 levels by uncertain causes, althoughsome relationship probably is present. The 7 functional feeding groups persist through most of the sampledinterval but harbor host-plants and arthropod herbivores that are spatiotemporally ephemeral. Poor understandingof associations in Phases 1 to 3 is attributed to disproportionate focus on the angiosperm and holometabolaninsect associations of Phase 4. 2006 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50540401 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.4 Vol.4 |
