Project description:Whole blood was collected as part of monthly veterinary checkups of bottlenose dolphins housed at Dolphing Quest in Waikoloa, Hawaii, USA. Gene expression from 5 samples was analyzed for comparison to the blood transcriptome of the beluga whale.
Project description:D. grimshawi microarray used to text for gene expression differences between two populations subjected to control or low-intensity heat for one week during maturation Anthropogenic influences on global processes and climatic conditions are increasingly affecting ecosystems throughout the world. Hawaii Island’s native ecosystems are well-studied and local long-term climatic trends well-documented, making these ecosystems ideal for evaluating how native taxa may respond to a warming environment. This study documents adaptive divergence of populations of a Hawaiian picture wing Drosophila, D. sproati, that are separated by only 7km and 365m in elevation. Representative laboratory populations show divergent behavioral and physiological responses to an experimental low-intensity increase in ambient temperature during maturation. The significant interaction of source population by temperature treatment for behavioral and physiological measurements indicates differential adaptation to temperature for the two populations. Significant differences in gene expression among males were mostly explained by the source population, with eleven genes in males also showing a significant interaction of source population by temperature treatment. The combined behavior, physiology, and gene expression differences between populations illustrates the potential for local adaptation to occur over a fine spatial scale and exemplifies nuanced response to climate change.
Project description:A dataset of corals sampled along the Puako area of Hawaii island as part of the NASA Ecological Forecasting program's "Fore-C" project. Samples consist of whole coral fragments extracted into methanol and later processed on a Thermo Vanquish Horizon UHPLC coupled to an Thermo Orbitrap ID-X Tribrid.
