Ecotypic Differentiation

Abstract Populations of widely distributed species often exhibit geographic variation in functional traits in response to environmental heterogeneity. Such trait variation may be the result of different adaptive mechanisms, including genetically based differentiation, phenotypic plasticity or a combination of both. Disentangling the genetic and environmental components of trait variation may be particularly interesting in crop wild relatives, since they may provide unique reservoirs of genetic diversity for crop improvement. In this study, we assessed ecotypic differentiation and patterns of plasticity to drought in populations of Lupinus angustifolius, a Mediterranean crop wild relative, from two climatically distinct regions in the Iberian Peninsula. Using an outdoor common garden, we compared phenotypic responses of inbred maternal families to two ecologically meaningful water availability treatments (drought and high-moisture). We measured 18 different functional traits related to growth, morphology, phenology and reproduction. Plants in the drought treatment grew less, had lower leaf chlorophyll content and photochemical efficiency, but also reproduced faster, produced larger seeds and altered leaflet morphology through increased leaflet thickness, higher leaflet dry matter content and lower specific leaf area. We also found significant differences between regions that likely reflect adaptation to climatically distinct environments, with populations from the south showing a faster onset of reproduction, higher leaf thickness and higher seed size, consistent with the drier conditions experienced in southern sites. Plasticity to drought was in most cases in the same direction as quantitative genetic differentiation (i.e. cogradient variation), providing evidence of the adaptive value of the plastic change. Our results show that both genetic differentiation and plasticity can generate adaptive phenotypic variation in L. angustifolius, and help to identify potentially valuable genetic resources to incorporate into breeding programmes.

Ecological Separation

Foeniculum piperitum was described as Anethum piperitum based on plants collected in Sicily, Italy. Currently it is treated either as a synonym of Foeniculum vulgare, or as one of two subspecies within that taxon. Here we show that F. vulgare and F. piperitum are two different, sometimes co-occurring, taxa and that given clear morphological and ecological separation, they should be treated as distinct species. Anethum piperitum is typified. Owing to misapplication of names and wrong synonymizations, the ecology and chorology of F. vulgare and F. piperitum have to be better defined.

A New Species

Abstract—Artocarpus bergii, named for the late C. C. Berg, is from Halmahera in the Moluccas, and is a close ally of breadfruit (A. altilis). The species resembles the Micronesian A. mariannensis but with generally smaller parts. Because it is known from only a small area and the type locality is a potential mining site, A. bergii is likely of conservation concern, particularly given its status as a crop wild relative.
