The evolution of convergence, growth, and diet under an adaptive landscape framework
… basis of microevolution. In microevolution, an adaptive landscape is used to visualize the relationship between phenotype and fitness, through a series of peaks and valleys. The adaptive landscape, as a concept suggests that there is some phenotypic optimum, or a combination of phenotypes, that …

Between Swamp and Sea: Agroforestry as Wetland Restoration in Southeast Virginia
… applied research design project investigates how adaptive landscape strategies can facilitate marsh migration without sacrificing forested wetland or productive value. Observational studies of marsh migration into coastal forests are well documented, though the mechanisms and determinants behind …

Microevolutionary processes in natural populations of the waterstrider Aquarius remigis
… evolution may be constrained by genetics, the adaptive landscape, development, and functional limitations. Optimal body size is determined by the net effect of selection acting throughout the life history of the organism. Body size is correlated between the sexes, and sexual size dimorphism …

Exploring the ecological and social benefits of the Khayelitsha Wetlands Park
… green spaces are important components of urban landscapes. Urban green spaces are defined as open spaces in urban areas primarily covered with vegetation, which are available to users within the community. They have the ability to shape the image of cities and provide various important …

Population-Level Differences in Pinus monophylla Whole-Plant Seedling Strategies Under Varying Precipitation Pulses
… adaptations to historic conditions may become maladaptive under projected climate scenarios. Singleleaf pinyon pine (Pinus monophylla) is a dominant tree species in the Intermountain West, USA, that demonstrates intraspecific trait variation along multiple climatic gradients, most notably climatic …

Mechanisms Promoting Spatial and Temporal Variability in Plant Defense
… influence the distribution, expression, and adaptive value of resistance and tolerance of goldenrod (Solidago altissima). Within replicate early- and late-successional fields, I quantified the spatial structure of herbivore damage and goldenrod resistance, tolerance, and fitness traits, and …
