Plant-associated microbial communities can profoundly affect plant health and success, and research is still uncovering factors driving the assembly of these communities. Here, we examine how geography versus host species affects microbial community structure and differential abundances of individual taxa. We use metabarcoding to characterize the bacteria and eukaryotes associated with five, often co-occurring species of Sarracenia pitcher plants (Sarraceniaceae) and three natural hybrids along the longitudinal gradient of the U.S. Gulf Coast, as well as samples from S. purpurea in Massachusetts. To tease apart the effects of geography versus host species, we focus first on sites with co-occurring …
Characterization And Comparison Of Convergence Among Cephalotus Follicularis Pitcher Plant-Associated Communities With Those Of Nepenthes And Sarracenia Found Worldwide, Leonora S. Bittleston, Elizabeth L. Benson, Jessica R. Bernardin, Naomi E. Pierce

The Albany pitcher plant, Cephalotus follicularis, has evolved cup-shaped leaves and a carnivorous habit completely independently from other lineages of pitcher plants. It is the only species in the family Cephalotaceae and is restricted to a small region of Western Australia. Here, we used metabarcoding to characterize the bacterial and eukaryotic communities living in C. follicularis pitchers at two different sites. Bacterial and eukaryotic communities were correlated in both richness and composition; however, the factors associated with richness were not the same across bacteria and eukaryotes, with bacterial richness differing with fluid color, and eukaryotic richness differing with the …

The effects of extrinsic environmental factors that shape ecological systems are not only seen at the macroscopic level, but additionally influence and govern the host-associated microbial communities of their mammalian hosts. These microbial communities are susceptible to the fluctuation of abiotic and biotic factors which affect their host organisms. The surge in the research of microbiota–communities of archaea, bacteria, fungi, and viruses residing in various environmental systems–has shown that these communities can profoundly influence animal health. As such, monitoring microbiota has allowed for a new approach to study animal health and physiology. This is of particular benefit in the conservation …

Microbiomes play essential roles in the health and function of animal and plant hosts and drive nutrient cycling across ecosystems. Integrating novel trait-based approaches with ecological theory can facilitate the prediction of microbial functional traits important for ecosystem functioning and health. In particular, the yield-acquisition-stress (Y-A-S) framework considers dominant microbial life history strategies across gradients of resource availability and stress. However, microbiomes are dynamic, and spatial and temporal shifts in taxonomic and trait composition can affect ecosystem functions. We posit that extending the Y-A-S framework to microbiomes during succession and across biogeographic gradients can lead to generalizable rules for how …
The Endosymbiotic Gut Fungus Zancudomyces Culisetae Influences Transstadial Transmission Of Host-Associated Microbiota In The Yellow Fever Mosquito (Aedes Aegypti), Jonas Frankel-Bricker
The Endosymbiotic Gut Fungus Zancudomyces Culisetae Influences Transstadial Transmission Of Host-Associated Microbiota In The Yellow Fever Mosquito (Aedes Aegypti), Jonas Frankel-Bricker
Boise State University Theses and Dissertations
Mosquitoes are vectors for a variety of human pathogens and have a significant impact on human health worldwide. There is growing evidence that host-associated microbiota influence mosquito vector competence for certain viruses. Transstadial transmission of bacteria from larvae through pupae to adults could affect these interactions, though further studies are needed to fully unravel the mechanisms involved. Current microbiome research primarily focuses on bacterial communities, whereas the potential role endosymbiotic gut fungi have in transstadial transmission dynamics remains largely unknown. Trichomycetes is an ecological group of endosymbiotic microfungi that colonize the digestive tracts of arthropod hosts, including the Yellow Fever …
