Data from: The genetic architecture of plant defense tradeoffs in a common monkeyflower

Nicholas Kooyers, Benjamin Blackman, Abigail Donofrio & Liza Holeski
Determining how adaptive combinations of traits arose requires understanding the prevalence and scope of genetic constraints. Frequently observed phenotypic correlations between plant growth, defenses, and/or reproductive timing have led researchers to suggest that pleiotropy or strong genetic linkage between variants affecting independent traits is pervasive. Alternatively, these correlations could arise via independent mutations in different genes for each trait and extensive correlational selection. Here we evaluate these alternatives by conducting a QTL mapping experiment involving...

Data from: Species loss drives ecosystem function in experiments, but in nature the importance of species loss depends on dominance

Mark A. Genung, Jeremy Fox & Rachael Winfree
Aim: Decades of experimental research have conclusively shown a positive relationship between species richness and ecosystem function. However, authoritative reviews find no consensus on how species loss affects function in natural communities. We analyse experimental and observational data in an identical way and test whether they produce similar results. Location: North America and Europe (experimental communities); global (natural communities). Time period: Experimental communities: 1998–2013; natural communities: 1982–2018. Major taxa studied: Experimental communities: temperate grassland plants;...

Strength in numbers? Cytotype frequency mediates effect of reproductive barriers in mixed-ploidy arrays.

Brittany Sutherland, Tomas Miranda-Katz & Laura Galloway
When differentiated lineages come into contact, their fates depend on demographic and reproductive factors. These factors have been well-studied in taxa of the same ploidy, but less is known about sympatric lineages that differ in ploidy, particularly with respect to demographic factors. We assessed prezygotic, postzygotic, and total reproductive isolation in naturally-pollinated arrays of diploid-tetraploid and tetraploid-hexaploid population mixes of Campanula rotundifolia by measuring pollinator transitions, seed yield, germination rate, and proportion of hybrid offspring....

Data from: Trophic niche size and overlap decreases with increasing ecosystem productivity

Justin Lesser, William James, Rachel Wilson, Chris Stallings & James Nelson
The production and transfer of biomass through trophic relationships is a core ecosystem function. The movement of energy through the food web is mediated by organisms operating in their niche space. For generalists, the size of this niche space is inherently plastic and changes in response to available food sources. Therefore, this relationship between ecosystem productivity and niche size is an important determinant of ecosystem function. Competing theories about the nature of this relationship predict...

Variation in frequency of plastid RNA editing within Adiantum (Pteridaceae) implies rapid evolution in fern plastomes

Blake Fauskee, Erin Sigel, Kathleen Pryer & Amanda Grusz
Premise Recent advances in studies of plant RNA editing have demonstrated that the number of editing sites can vary widely among large taxonomic groups (orders, families). Yet, very little is known about intrageneric variation in frequency of plant RNA editing, and no study has been conducted in ferns. Methods We determined plastid RNA editing counts for two species of Adiantum (Pteridaceae), A. shastense and A. aleuticum, by implementing a pipeline that integrated read mapping and...

Caribbean Roseate Tern nest survival and monitoring data

Paige Byerly, Paul Leberg & Susan Zaluski
Determining how site characteristics influence reproductive success can help guide conservation planning for declining wildlife populations. For colonially-breeding seabirds, nest survival and predation risk can be influenced by both colony and nest site characteristics such as colony size, nest density, and nest location. We evaluated reproductive success of a declining population of Roseate Terns (Sterna dougallii) in the U.S. and British Virgin Islands to identify primary causes of nest failure and investigate the influence of...

Regional Invasive Species & Climate Change Management Challenge: Gardening with climate-smart native plants in the Northeast

Bethany A. Bradley, Amanda Bayer, Bridget Griffin, Sydni Joubran, Brittany B. Laginhas, Lara Munro, Sam Talbot, Jenica M. Allen, Audrey Barker-Plotkin, Evelyn M. Beaury, Carrie Brown-Lima, Emily J. Fusco, Hayley Mount, Bailey Servais & Toni Lyn Morelli
An estimated 80% of ornamental plants for sale are non-native. This means that the average yard does a poor job of supporting native flora and fauna. By shifting our plantings towards natives, we can dramatically increase the diversity of bees, butterflies, birds and other animals. In contrast, non-native plants do not support local food webs and can become invasive. Native plants increase biodiversity and reduce risks associated with invasive species, which supports resilient ecosystems in...
