Abstract: The long‐term success of restored populations may be jeopardized by the collection locality of transplants if they are ill matched to their new environment. The home‐site advantage hypothesis predicts that the relative success of introduced populations will decrease as their genetic and environmental distance to the local native population increases. We evaluated this hypothesis for a geographically variable shrub, Lotus scoparius, in southern Californian coastal sage scrub by… 

Nonlocal transplantation and outbreeding depression in the subshrub Lotus scoparius (Fabaceae).

The genetic background of transplants used to create or augment wild populations may affect the long-term success of restored populations. If seed sources are from differently adapted populations,

Reintroduction of Castilleja levisecta: Effects of Ecological Similarity, Source Population Genetics, and Habitat Quality

Although measures of genetic diversity, population size, and geographic distance are often used to make conservation decisions during species recovery, here they were poor predictors of C. levisecta performance and establishment.

Regional and Ecotype Traits in Lotus corniculatus L., with Reference to Restoration Ecology

Differences in phenotype and fecundity between geographically separated populations of L. corniculatus may be sufficient to lead to differences in survival and fitness when seeds are sown in a restoration environment.

Effects of crossing distance on performance of the native wildflower Lobelia siphilitica: Implications for ecological restoration1

Mixed support for the recommendation that restoration projects use seed collected from geographically proximate populations is found, and factors other than geographic distance, particularly climatic distance, need to be considered when selecting seed sources for ecological restoration projects.

Testing the Home‐Site Advantage in Forest Trees on Disturbed and Undisturbed Sites

Evidence for enhanced establishment from local seed in at least one species leads us to recommend that where sufficient high-quality seed supplies exist locally, these should be used in restoration.

Local adaptation in the monocarpic perennial Carlinavulgaris at different spatial scales across Europe

Spatial variation in environmental conditions can lead to local adaptation of plant populations, particularly if gene flow among populations is low. Many studies have investigated adaptation to

Local Adaptation and the Effects of Isolation and Population Size – the Semelparous Perennial Carlina vulgaris as a Study Case

No evidence of local adaptation in terms of native superiority compared to non-natives is found, but with the relative method, one of six fitness components, juvenile survival, is found to be 6% higher for natives at their home sites compared to how they performed at other sites and how others performed at their site.

Which factors limit the etablishement of brachypodium retusum : a key species in ecological restoration of Mediterranean steppes ?

Adaptive differentiation between populations may have contributed to regional differences in colonisation capacity and needs to be taken into account in targeting source populations for plant introduction in ecological restoration.

Adaptive differentiation among populations of the Mediterranean dry grassland species Brachypodium retusum: The role of soil conditions, grazing, and humidity.

Adaptive population differentiation in germination and early growth may have contributed to different colonization patterns for Brachypodium retusum, a common Mediterranean grass, and the provenance needs to be carefully considered in ecological restoration.



Outplanting and Differential Source Population Success in Lupinus guadalupensis

The results suggest that large populations are better sources of seeds for outplanting in L. guadalupensis and that out Planting is most successful in sites where plants are least subject to desiccation, as well as investigating the pattern of adaptation in populations of an annual, island endemic plant.

Patterns of Differentiation in Wiregrass (Aristida beyrichiana): Implications for Restoration Efforts

This result, when combined with previous results indicating local adaptation in later life stages of wiregrass, suggests that restoration efforts involving this species should use local seed sources from sites with similar soil and hydrological conditions.

Reciprocal transplantations of Spartina patens genotypes from adjacent salt marsh, swale, and dune habitats provided evidence for genetic differentiation among subpopulations, due at least in part to

The Effects of Surrounding Vegetation and Transplant Age on the Detection of Local Adaptation in the Perennial Grass Aristida Stricta

The effect of transplant age on the detection ofpopulation differentiation suggests that evidence of population differentiation may not always be apparent because of temporal variation in environmental conditions.

Geographic distribution of flower morphological traits in subspecies of Lotus scoparius

Canonical correlation analysis showed that elevation, annual rainfall, and growing season evapotranspiration were moderately correlated with the distinguishing flower traits, however, among transition zone sites no partitioning of the environment was evident and an evolutionary and biogeographic scenario is proposed.

Comparison of Isozymes and Quantitative Traits for Evaluating Patterns of Genetic Variation in Purple Needlegrass (Nassella pulchra)

The close association of quantitative trait variation with regional climatic variables indicates that an index based on readily obtainable climatic information might aid restorationists in making rapid decisions about appropriate spatial scales for translocating native grasses.

Pollen dispersal and optimal outcrossing in Delphinium nelsoni

It is suggested that outbreeding depression will often occur on a much finer scale than previously recognised, especially in plants subject to restricted pollen and seed dispersal, and a short outcrossing distance is optimal for Delphinium nelsoni Greene.

Life history variation in blue flax (Linum perenne: Linaceae): seed germination phenology

Results demonstrated the existence of ecologically relevant among-population and within-population variation in germination phenology for blue flax and suggested that differences both among and within populations may be genetically based.

Biodiversity Resources for Restoration Ecology

Local natural areas should be used as templates of community composition and structure from which one measures success in the evaluation phase of restoration, and the value of preserving local habitat remnants is high and complements their usefulness as a source of ecologically precise material for installation.

Examination of the degree and extent of multiple paternity within individual fruits set in a small, isolated population of Raphanus sativus in southern California found multiple paternity occurred frequently, involving all of the assayed parents and at least 85% of the fruits overall.
