Data from: Primer development for the plastid region ycf1 in Annonaceae and other magnoliids

Kurt M. Neubig & J. Richard Abbott
PREMISE OF THE STUDY: Primers were developed for a portion of the ycf1 plastid gene in magnoliid taxa to investigate the utility of ycf1 in phylogenetic analyses. METHODS AND RESULTS: Twenty-six species across six families within the magnoliid group (Canellales, Piperales, Laurales, and Magnoliales) were sampled to examine the ability to amplify ycf1. Additionally, 29 accessions of Asimina and Deeringothamnus (Annonaceae) were sequenced to assess levels of variation in ycf1 compared to matK and trnL-F....

Data from: Partial incubation during egg laying reduces eggshell microbial loads in a temperate‐breeding passerine

Patricia B. Bollinger, Eric K. Bollinger, Steven L. Daniel, Rusty A. Gonser & Elaina M. Tuttle
Incubation prior to clutch completion may be adaptive if it maintains egg viability by inhibiting eggshell microbial growth, thus reducing the likelihood that the embryo becomes infected. To test this hypothesis, we examined the effect of partial incubation during egg laying on eggshell microbial loads in eastern bluebirds Sialia sialis breeding at a temperate‐zone site. We sampled eggshell microbes prior to and following four days of exposure to either partial incubation during the laying period...

Data from: Soil microbial communities alter leaf chemistry and influence allelopathic potential among coexisting plant species

Scott J. Meiners, Kelsey K. Phipps, , Thomas Canam, Walter P. Carson & Thomas H. Pendergast
While both plant–soil feedbacks and allelochemical interactions are key drivers of plant community dynamics, the potential for these two drivers to interact with each other remains largely unexplored. If soil microbes influence allelochemical production, this would represent a novel dimension of heterogeneity in plant–soil feedbacks. To explore the linkage between soil microbial communities and plant chemistry, we experimentally generated soil microbial communities and evaluated their impact on leaf chemical composition and allelopathic potential. Four native...

Data from: Species colonisation, not competitive exclusion, drives community overdispersion over long-term succession

Shao-Peng Li, Marc W. Cadotte, Scott J. Meiners, Zheng-Shuang Hua, Lin Jiang & Wen-Sheng Shu
Ecological communities often transition from phylogenetic and functional clustering to overdispersion over succession as judged by space-for-time substitution studies. Such a pattern has been generally attributed to the increase in competitive exclusion of closely related species with similar traits through time, although colonisation and extinction have rarely been examined. Using 44 years of uninterrupted old-field succession in New Jersey, USA, we confirmed that phylogenetic and functional clustering decreased as succession unfolded, but the transition was...

Data from: Species pools and differential performance generate variation in leaf nutrients between native and exotic species in succession

Kirstin I. Duffin, Shaopeng Li, Scott J. Meiners & Shao-Peng Li
1. A central aim of invasion biology has been to identify key functional differences between native and exotic species to determine which traits may be responsible for invasion success and impacts. There are two primary ways that differences may exist between native and exotic species - the traits of the local species pools may differ, or the way that the traits interact with their environment may differ. 2. We explored leaf nutrient concentrations as functional...

Data from: Geographic variation in larval metabolic rate between northern and southern populations of the invasive gypsy moth

Carolyn May, Noah Hillerbrand, Lily M. Thompson, Trevor M. Faske, Eloy Martinez, Dylan Parry, Salvatore J. Agosta & Kristine L. Grayson
Thermal regimes can diverge considerably across the geographic range of a species, and accordingly, populations can vary in their response to changing environmental conditions. Both local adaptation and acclimatization are important mechanisms for ectotherms to maintain homeostasis as environments become thermally stressful, which organisms often experience at their geographic range limits. The spatial spread of the gypsy moth (Lymantria dispar L.) after introduction to North America provides an exemplary system for studying population variation in...

Data from: Phylogenetic utility of ycf1 in orchids: a plastid gene more variable than matK

Kurt M. Neubig, W. Mark Whitten, Barbara S. Carlsward, Mario A. Blanco, Lorena Endara, Norris H. Williams & Michael Moore
Plastid DNA sequences have been widely used by systematists for reconstructing plant phylogenies. The utility of any DNA region for phylogenetic analysis is determined by ease of amplification and sequencing, confidence of assessment in phylogenetic character alignment, and by variability across broad taxon sampling. Often, a compromise must be made between using relatively highly conserved coding regions or highly variable introns and intergenic spacers. Analyses of a combination of these types of DNA regions yield...
