Broad diversity in monoterpene–sesquiterpene balance across wild sunflowers: Implications of leaf and floral volatiles for biotic interactions Open
Premise As plant lineages diversify across environmental gradients, species are predicted to encounter divergent biotic pressures. This study investigated the evolution of volatile secondary metabolism across species of Helianthus . Method…

Gene co-expression reveals the modularity and integration of C4 and CAM in <i>Portulaca</i> Open
C4 photosynthesis and Crassulacean acid metabolism (CAM) have been considered as largely independent adaptations despite sharing key biochemical modules. Portulaca is a geographically widespread clade of over 100 annual and perennial angio…

Conservation threats from roadkill in the global road network Open
Aim The road network is increasing globally but the consequences of roadkill on the viability of wildlife populations are largely unknown. We provide a framework that allows us to estimate how risk of extinction of local populations increa…

Large Mammals Have More Powerful Antibacterial Defenses Than Expected from Their Metabolic Rates Open
Terrestrial mammals span 7 orders of magnitude in body size, ranging from the < 2 g pygmy shrew ( Suncus etruscus ) to the > 3900 kg African elephant ( Loxodonta africana ). Although body size has profound effects on the behavior, physiolo…

Evolution of Disease Severity and Susceptibility in the Asteraceae to the Powdery Mildew <i>Golovinomyces latisporus</i>: Major Phylogenetic Structure Coupled With Highly Variable Disease Severity at Fine Scales Open
Pathogen host range and pathogen severity are dependent on interactions with their hosts and are hypothesized to have evolved as products of a coevolutionary arms race. An understanding of the factors that affect host range and pathogen se…

Learning from Dynamic Traits: Seasonal Shifts Yield Insights into Ecophysiological Trade-Offs across Scales from Macroevolutionary to Intraindividual Open
Premise of the Research. Phylogenetic comparative methods provide a powerful approach for exploring the macroevolution of plant functional traits. Such approaches can uncover trait-trait correlations through evolutionary time, as well as p…

Measuring inferential importance of taxa using taxon influence indices Open
Assessing the importance of different taxa for inferring evolutionary history is a critical, but underutilized, aspect of systematics. Quantifying the importance of all taxa within a dataset provides an empirical measurement that can estab…

Molecular evolution of key metabolic genes during transitions to C<sub>4</sub> and <span>CAM</span> photosynthesis Open
Premise of the Study Next‐generation sequencing facilitates rapid production of well‐sampled phylogenies built from very large genetic data sets, which can then be subsequently exploited to examine the molecular evolution of the genes them…

Targeted Enrichment of Large Gene Families for Phylogenetic Inference: Phylogeny and Molecular Evolution of Photosynthesis Genes in the Portullugo Clade (Caryophyllales) Open
Hybrid enrichment is an increasingly popular approach for obtaining hundreds of loci for phylogenetic analysis across many taxa quickly and cheaply. The genes targeted for sequencing are typically single-copy loci, which facilitate a more …

Rapid maximum likelihood ancestral state reconstruction of continuous characters: A rerooting‐free algorithm Open
Ancestral state reconstruction is a method used to study the evolutionary trajectories of quantitative characters on phylogenies. Although efficient methods for univariate ancestral state reconstruction under a Brownian motion model have b…
Importance of whole-plant biomass allocation and reproductive timing to habitat differentiation across the North American sunflowers Open
Herbaceous taxa can adapt to diverse environments in many ways, including modulation of phenology, plant architecture and organ-level ecophysiology. Although leaf economic strategy captures one key aspect of plant physiology, on their own …

Fine root tradeoffs between nitrogen concentration and xylem vessel traits preclude unified whole‐plant resource strategies in <i>Helianthus</i> Open
Recent work suggests variation in plant growth strategies is governed by a tradeoff in resource acquisition and use, ranging from a rapid resource acquisition strategy to a resource‐conservative strategy. While evidence for this tradeoff h…
