Floral spectral reflectance data for: Floral color properties of serpentine seep assemblages depend on community size and species richness

Kathryn LeCroy, Gerardo Arceo-Gómez, Matthew Koski, Nathan Morehouse & Tia-Lynn Ashman
Functional traits, particularly those that impact fitness, can shape the ecological and evolutionary relationships among coexisting species of the same trophic level. Thus, examining these traits and properties of their distributions (underdispersion, overdispersion) within communities can provide insights into key ecological interactions (e.g., competition, facilitation) involved in community assembly. For instance, the distribution of floral colors in a community may reflect pollinator-mediated interactions between sympatric plant species, and the phylogenetic distribution of color can inform...

Rare missense functional variants at COL4A1 and COL4A2 in sporadic intracerebral hemorrhage

Objective To test the genetic contribution of rare missense variants in COL4A1 and COL4A2 in which common variants are genetically associated with sporadic intracerebral hemorrhage (ICH), we performed rare variant analysis in multiple sequencing data for the risk for sporadic ICH. Methods We performed sequencing across 559Kbp at 13q34 including COL4A1 and COL4A2 among 2,133 individuals (1,055 ICH cases; 1,078 controls) in US-based and 1,492 individuals (192 ICH cases; 1,300 controls) from Scotland-based cohorts, followed...

Datasets associated with: Late Holocene spread of pastoralism coincides with endemic megafaunal extinction on Madagascar

Recently expanded estimates for when humans arrived on Madagascar (up to ~10,000 years ago) highlight questions about the causes of the island’s relatively late megafaunal extinctions (~2000-500 years ago). Introduced domesticated animals could have contributed to extinctions, but the arrival times and past diets of exotic animals are poorly known. To conduct the first explicit test of the potential for competition between introduced livestock and extinct endemic megafauna in southern and western Madagascar, we generated...

Patterns of recent natural selection on genetic loci associated with sexually differentiated human body size and shape phenotypes

Audrey M. Arner, Kathleen E. Grogan, Mark Grabowski, Hugo Reyes-Centeno & George H. Perry
Levels of sex differences for human body size and shape phenotypes are hypothesized to have adaptively reduced following the agricultural transition as part of an evolutionary response to relatively more equal divisions of labor and new technology adoption. In this study, we tested this hypothesis by studying genetic variants associated with five sexually differentiated human phenotypes: height, body mass, hip circumference, body fat percentage, and waist circumference. We first analyzed genome-wide association (GWAS) results for...

Data from: Colour use by tiny predators: jumping spiders exhibit colour biases during foraging

Lisa Taylor, Emily Maier, Kevin Byrne, Zareen Amin & Nathan Morehouse
The evolution of many animal colours is thought to be driven by selection from visually guided predators. Yet research has largely focused on large vertebrate predators such as birds while ignoring smaller, terrestrial invertebrate predators. This is despite clear evidence that small invertebrate predators are important regulators of prey densities in a variety of ecosystems. Jumping spiders are small voracious predators that feed on a wide variety of prey in the field. They are capable...

Phytochemistry reflects different evolutionary history in traditional classes versus specialized structural motifs

Kathryn Uckele, Joshua Jahner, Eric Tepe, Lora Richards, Lee Dyer, Kaitlin Ochsenrider, Casey Philbin, Massuo Kato, Lydia Yamaguchi, Matthew Forister, Angela Smilanich, Craig Dodson, Christopher Jeffrey & Thomas Parchman
Foundational hypotheses addressing plant-insect codiversification and plant defense theory typically assume a macroevolutionary pattern whereby closely related plants have similar chemical profiles. However, numerous studies have documented variation in the degree of phytochemical trait lability, raising the possibility that phytochemical evolution is more nuanced than initially assumed. We utilize proton nuclear magnetic resonance (1H NMR) data, chemical classification, and double digest restriction-site associated DNA sequencing (ddRADseq) to resolve evolutionary relationships and characterize the evolution of...
