We discuss the first phase of development of the Volusia Sandhill Ecosystem, a teaching landscape on the grounds of the Gillespie Museum, on the DeLand, FL, campus of Stetson University. Since its initiation in 2011 with the planting of a canopy of 8

Plants are often genetically specialized as ecotypes attuned to local environmental conditions. When conditions change, the optimal environment may be physically displaced from the local population, unless dispersal or in situ evolution keep pace, re

Moist tussock tundra, dominated by the sedge Eriophorum vaginatum L., covers approximately 3.36 × 108 km2 of arctic surface area along with large amounts of subarctic land area. Eriophorum vaginatum exhibits ecotypic differentiation along latitudina

Premise of the study: In a large reciprocal transplant experiment, Eriophorum vaginatum tussocks transplanted along a latitudinal gradient in Alaska’s interior exhibited genetic differentiation and phenotypic plasticity for vegetative traits. Us

Summary 1. Reciprocal transplant experiments designed to quantify genetic and environmental effects on phenotype are powerful tools for the study of local adaptation. For long-lived species, especially those in habitats with short growing seasons, ho

Asclepias curtissii (Curtiss' Milkweed) is an endangered perennial herbaceous plant endemic to Florida scrub habitat. Although many scrub perennials are gap specialists, Curtiss' Milkweed is often found growing in close association with woody vegetat

Selection may maintain genetic diversity in natural populations if the physical or biotic environment is variable over space and-or time. Because density and genotype frequencies can be heterogeneous, and because genotypes may differ in competitive a

Population response to selection depends on the presence of additive genetic variance for traits under selection. When a population enters an alien environment, environment-induced changes in the expression of genetic variance may occur. These could

One possible response of plant populations to heterogeneous environments is genetic adaptation resulting in the formation of distinct ecotypes. Genetic adaptation to stressful environments may affect both the limits to species boundaries and the pote
