In this era of rapid global change, factors influencing the stability ecosystems and their functions have come into spotlight. For decades relationship between complexity has been investigated in modeled empirical systems, yet results remain largely context dependent. To overcome we leverage a multiscale inventory fungi bacteria ranging from single sites along an environmental gradient, to habitats inclusive land, sea stream, entire watershed. We use networks assess microbiome robustness...
An essential question in evolutionary biology is whether shifts a set of polygenic behaviors share genetic basis across species. Such behavioral shift seen the cave-dwelling Mexican tetra, Astyanax mexicanus. Relative to surface-dwelling conspecifics, cavefish do not school (asocial), are hyperactive and sleepless, adhere particular vibration stimulus (imbalanced attention), behave repetitively, show elevated stress hormone levels. Interestingly, these traits largely overlap with core...
Microbes are found in nearly every habitat and organism on the planet, where they critical to host health, fitness, metabolism. In most organisms, few microbes inherited at birth; instead, acquiring microbiomes generally involves complicated interactions between environment, hosts, symbionts. Despite criticality of microbiome acquisition, we know little about hosts’ reside when not or hosts interest. Because span a continuum ranging from generalists associating with multiple habitats...
Ozonolysis combined with DART MS analysis provides a facile method for the identification of double bond position in lipids.
Abstract Reproduction is highly dependent on environmental and physiological factors including nutrition, mating stimuli microbes. Among these factors, microbes facilitate vital functions for host animals such as nutritional intake, metabolic regulation, enhancing fertility under poor nutrition conditions. However, detailed molecular mechanisms by which control germline maturation, leading to reproduction, remain largely unknown. In this study, we show that exert a beneficial effect...
Lipid pheromones play a significant role in the behavior and ecology of many insects. The characterization pheromone structures is challenge due to their low abundance ephemeral nature. Here we present method for analysis lipid molecules from single glands Drosophila melanogaster (fruit fly) using Direct Analysis Real Time mass spectrometry (DART MS). Our results reveal that DART MS tissues generates reproducible, species-specific profiles comprised fatty acids, wax esters, diacylglycerides...
Abstract Plant microbiomes are shaped by forces working at different spatial scales. Environmental factors determine a pool of potential symbionts while host physiochemical influence how those microbes associate with distinct plant tissues. Interactions between these scales, however, seldom considered. Here we analyze epiphytic from nine Hibiscus tiliaceus trees across steep environmental gradient within single Hawaiian watershed. At each location sampled eight microhabitats: leaves,...
