Reciprocal Transplant and Machine Learning Study of Oak Mistletoe on Three Host Oak Species in Santa Margarita, California
… called supervised classification as well as a reciprocal transplant study in the field. The three species of oak trees were classified with 87% accuracy using drone imagery and 95% accuracy using open source NAIP imagery. This classification technique could be applied to the whole state of …

Circadian regulation and natural variation of low temperature signaling in Arabidopsis
… tested for fitness (survival and seed set) in reciprocal transplant experiments. Reciprocal transplant experiments revealed that home accessions at both sites had a strong advantage in terms of seed-set and survival. SW and IT recombinant inbred lines (RILs) were used to define fitness QTL in …

Isolating Confounding Abiotic and Biotic Effects on the Phenotype on Physa Acuta Snails
… were more elongate with smaller apertures. In a reciprocal transplant lab experiment that crossed flow regime and crayfish predator cues, I tested for the underlying mechanisms responsible for the observed phenotypic differences. I found no evidence for plasticity in relation to flow regime. …

Testing Subspecies Limits in <i>Monardella Villosa</i>
… were genetically based. I also conducted a reciprocal transplant of the two subspecies between inland and coastal populations to determine if they are locally adapted.</p> <p>The morphological differences (leaf hair density and length as well as leaf base angle) between subspecies were …

Influence of site and soil type on the distribution of anthrax infectious sites and the contribution of anthrax to elephant mortality in Ethosha National park, Namibia
… and site on the persistence of B. anthracis, a reciprocal transplant experiment was conducted at three experimental sites across ENP following the rainfall gradient in which soil cores were spiked with a virulent B. anthracis strain. Sampling was done over 12 months to determine the persistence …

Life History Variation In Artemisia Campestris On A Lake Huron Sand Dune System
… under uniform conditions at two locations and a reciprocal transplant-replant experiment was performed.;The degree of polycarpy found was small and limited to one habitat, the heavily vegetated "transition zone". The ratio of juvenile to seedling survivorship was close to 1 in this habitat. …

VARIATION, ADAPTATION AND REPRODUCTIVE BIOLOGY IN RUPPIA MARITIMA L POPULATIONS FROM NEW HAMPSHIRE COASTAL AND ESTUARINE TIDAL MARSHES
… phenomena in Ruppia populations is discussed. A reciprocal transplant field study and a controlled environment greenhouse experiment contribute to an assessment of autecological data. Morphological variation in vegetative organs, reproductive parts and in the pollen was observed.</p><p>Coastal …

Environmental and Biotic Drivers of Seaweed–Bacterial Interactions: Insights into the Seaweed Holobiont
… holobiont assembly. Through conducting reciprocal transplant experiments, we demonstrate that seaweed-associated bacteria are locally adapted to their host species, with bacterial isolates exhibiting significantly higher fitness in their native host environment. Chapter 4 then …

Climatic specialisation: an explanation for the range size and distribution of bryophytes on a tropical island elevational gradient
… idea of ecophysiological specialisation using reciprocal transplant experiments, along with direct laboratory measurements of species' responses to desiccation and temperature. In these experiments I use species restricted to low, mid or high elevation, as well as widespread species found along …

Physiological, population, and genetic responses of an aquatic insect (Isonychia bicolor) to chronic mercury pollution
… of mercury at warmer temperatures. Results of reciprocal transplant experiments conducted at sites on the South River suggested that population differences in maintenance costs observed in short-term laboratory experiments, may have been reflected by population differences in fecundity in …

Assessing genomic variation in the hopbush, Dodonaea viscosa, to investigate micro-evolution and adaptation
… here is required. The use of common garden and reciprocal transplant experiments in order to provide evidence for links between genotype and phenotype and to asses the relative roles of genetic adaptation and plasticity in this species are discussed.

Evidence for Local Adaptation in Birds
… of Yellow Warblers (Dendroica petechia) using reciprocal nest transplant experiments between a temperate and subarctic site in Canada. Yellow Warblers breeding at our subarctic site build larger nests constructed with more insulative materials than Yellow Warblers breeding at our temperate …

The influence of Microhodotermes viator nest density and dispersion on ecological processes
… soils were quantified and compared and used for reciprocal greenhouse germination and growth experiments, which were supplemented with reciprocal in situ transplant and growth experiments. Germination trials tracked the germination and growth success of seeds from three plant species that occur …
