Intraspecific variation in Erica coccinea
… like many other Cape Erica species, has high intraspecific variability between populations. In addition to variability in floral characteristics such as colour, this species includes two distinct regeneration forms: a resprouter form which survives fire by resprouting from dormant buds in a …

Plant size and intraspecific variability in vascular epiphytes
… the most important taxonomic groups, the intraspecific variability in PC was almost always higher than the interspecific variability when comparing only large individuals. In situ studies with the epiphytic bromeliad V. sanguinolenta revealed that besides physiological parameters (such as …

Intraspecific plant polyploidy effects on goldenrod insect herbivores
<p>Polyploidy is a dynamic process underlying a significant component of angiosperm diversity. This thesis research explores ploidy level as a source of genetic variability within a plant species, Solidago altissima L. (Asteraceae) and how this variation influences its herbivore community. More …

Intraspecific competition in Leucadendron xanthoconus (O.Knutze) K. Shun
… dimorphism, does the importance and intensity of intraspecific competition vary? Does the pollination biology of dioecious, sexually dimorphic species influence niche partitioning?

Intraspecific trait variation and community assembly in old-field grasslands
… within species. Here I investigated the role of intraspecific trait variation in community assembly and responses to spatial and temporal environmental variation in old-field plant communities in the eastern United States. In the first study I analyzed spatial patterns of functional divergence in …

Accounting for intraspecific variation transforms our understanding of artiodactyl social evolution
… the evolution of social traits but have omitted intraspecific variation in social organization (IVSO) and mating systems (IVMS). My objectives were to (i) summarize the extent of IVSO and IVMS in Artiodactyla and Perissodactyla and (ii) determine the ancestral social organization and mating …

Sexual dimorphism, resource partitioning and intraspecific aggression in Caprella californica Stimpson
… and population structure as well as describing intraspecific aggressive behavior of Caprella californica Stimpson. ~- californica is dioecious and has marked sexual dimorphism in both its size and secondary sex characteristics. It is found from San Diego to the South China Sea (Laubitz, 1970), …

Intraspecific Variation Among Emerald Shiners (Notropis atherinoides) of the Missouri River
… four analyses to determine if l) there were any intraspecific differences among sites, 2) the differences were related to a genetic population structure, 3) the differences were correlated with habitat types, and 4) if the differences provided a measurable performance advantage. Emerald shiners …

The Significance of Inter- and Intraspecific DNA Content Variation in Agriculturally Important Species
This dissertation examined the total nuclear DNA content variation in agriculturally important plant species and determined any differences. The nuclear DNA content of 40 Malus species and hybrids was examined using flow cytometry. Estimates of total nuclear DNA content for this collection ranged …

Intraspecific variation in environmental and geographic space use: insights from individual movement data
Species’ ranges arise from the interplay between environmental preferences, biotic and abiotic environmental conditions, and accessibility. Understanding of – and predictive models on – species distributions often build from the assumption that these factors apply homogenously within each species, …

The evolution of intraspecific variation, growth, and body size in early theropod dinosaurs
… dinosaurs possessed an extremely high amount of intraspecific variation in growth. This variation had been previously interpreted as sexual difference; however, I found no evidence of this. Because this variation is widespread among early dinosaurs and their relatives, I hypothesize that this is …

The influence of intraspecific variation in host plants on arthropod and fungal endophyte communities
An appreciation for intraspecific variation is central to the study of evolutionary biology, however community ecologists have often assumed equivalence among conspecific organisms. In recent years, intraspecific genetic variation, particularly in plants, has received more attention, and has been …
