41 (6), pp. 1357-1369. ISSN 0014-3820. Available under: doi: 10.2307/2409100 Premise of the study: Most orchid species native to the Macaronesian islands reflect immigration from western Europe or North Africa followed by anagenesis. The only putative exception is the butterfly orchids (Platanthera) of the Azores, where three species apparently reflect at least one cladogenetic speciation event. This multidisciplinary study explores the origin, speciation, phenotypic Heterochrony refers to an alteration in time, or a change in order, of one or more events.

The Biological Species Concept - A natural This relationship between genetic and developmental dissimilarity is consistent with there being a genetic basis for variation in developmental timing and so suggests that intraspecific heterochrony could provide the raw material for natural selection to produce speciation. 1997-01-01 2002-03-19 Ontogenetic and morphological variation in 40 populations of the closely related species, Eucalyptus risdonii Hook.f. (Risdon Peppermint) and E. tenuiramis Miq. (Silver Peppermint), was assessed in a multivariate study of heteroblastic leaf (adult and juvenile) and fruit characters.

Hoboken, N.J.: Wiley-Liss 10.1002/jez.b.21083 Differences in diet and possibly in feeding mode are believed to have caused these phenotypic changes. Phenotypic plasticity is described in terms of a qualitative model of heterochrony in which phenotypic change in morphology is explained as retardation of the normal developmental rate. This similarity confirms inferences from phylogenetic reconstructions that linked multiple recent speciation events in salamander families with intraspecific heterochrony (Shaffer 1984).
