Spenders versus savers: climate-induced carbon allocation tradeoffs in a recently introduced woody plant

Randall Long, Tom Dudley, Carla D'Antonio, Kevin Grady, Susan Bush & Kevin Hultine
Non-structural carbohydrate(NSC) storage may be under strong selection in woody plant species that occur across strong environmental gradients. We therefore investigated carbon allocation strategies in a widely distributed, introduced woody plant. We predicted genotypes from cold climates with exposure to episodic freeze events, would have elevated NSC concentrations with the tradeoff of reduced growth and reproduction relative to warm-adapted genotypes. We established an experimental common garden using genotypes of Tamarix spp., sourced across a large...

Fungal infection alters the selection, dispersal, and drift processes structuring the amphibian skin microbiome

Mark Q Wilber, Andrea J Jani, Joseph R Mihaljevic & Cheryl J Briggs
Symbiotic microbial communities are important for host health, but the processes shaping these communities are poorly understood. Understanding how community assembly processes jointly affect microbial community composition is limited because inflexible community models rely on rejecting dispersal and drift before considering selection. We developed a flexible community assembly model based on neutral theory to ask: How do dispersal, drift, and selection concurrently affect the microbiome across environmental gradients? We applied this approach to examine how...
