Disentangling lousy relationships: Comparative phylogenomics of two sucking louse lineages parasitizing chipmunks

Kayce Bell, Julie M. Allen, Kevin P. Johnson, John R. Demboski & Joseph A. Cook
The evolution of obligate parasites is often interpreted in light of their hosts’ evolutionary history. An expanded approach is to examine the histories of multiple lineages of parasites that inhabit similar environments on a particular host lineage. Western North American chipmunks (genus Tamias) have a broad distribution, a history of divergence with gene flow, and host two species of sucking lice (Anoplura), Hoplopleura arboricola and Neohaematopinus pacificus. From total genomic sequencing, we obtained sequences of...

Complex histories of gene flow and a mitochondrial capture event in a non-sister pair of bird

Ethan Gyllenhaal, Michael Andersen, Jenna McCullough, Xena Mapel, Tri Haryoko, Knud Jønsson & Leo Joseph
Hybridization, introgression, and reciprocal gene flow during speciation, specifically the generation of mitonuclear discordance, are increasingly observed as parts of the speciation process. Genomic approaches provide insight into where, when, and how adaptation operates during and after speciation and can measure historical and modern introgression. Whether adaptive or neutral in origin, hybridization can cause mitonuclear discordance by placing the mitochondrial genome of one species (or population) in the nuclear background of another species. The latter,...

Telemetry validated nitrogen stable isotope clocks identify ocean-to-estuarine habitat shifts in mobile organisms

Oliver Shipley, Alisa Newton, Michael Frisk, Gregory Henkes, Jake LaBelle, Merry Camhi, Michael Hyatt, Hans Walters & Jill Olin
1. Throughout their life history, many animals transition among heterogenous environments to facilitate behaviors such as reproduction, foraging, and predator avoidance. The dynamic environmental and biological conditions experienced by mobile species are integrated in the chemical composition of their tissues, providing retrospective insight into movement. 2. Here, we present a unique nitrogen stable isotope clocks (‘isotopic clocks’), which integrate tissue turnover rates, consumer stable isotope ratios, and habitat-specific isotope baselines and can be used to...

Still time for action: genetic conservation of imperiled South Canadian River fishes, Arkansas River Shiner (Notropis girardi), Peppered Chub (Macrhybopsis tetranema) and Plains Minnow (Hybognathus placitus)

Megan Osborne, Joanna Hatt, Eliza Gilbert & Stephen Davenport
Pelagic broadcast spawning cyprinids have declined throughout the North American Great Plains because of adverse habitat changes caused by river fragmentation and altered flow regimes. Despite losses elsewhere, a 218-river kilometer section of the South Canadian River maintains three of these imperiled species: Arkansas River Shiner, Peppered Chub and Plains Minnow. The objective of this study was to determine if species occupying the same river stretch and hence a shared environment, exhibit the same trajectory...

Future fire-driven landscape changes along a southwestern US elevation gradient

Matthew Hurteau & Cecile Remy
Over the 21st century, the combined effects of increased fire activity and climate changes are expected to altered forest composition and structure in many ecosystems by changing post-fire successional trajectories and recovery. The southwestern US mountains encompass varied vegetation types and species according to elevation which do not respond the same to changing climate and fire regime. Moreover, fire exclusion applied during the early 20th century has altered forest structure and fuel loads compared to...

Elucidating gene expression adaptation of phylogenetically divergent coral holobionts under heat stress

Viridiana Avila-Magaña, Bishoy Kamel, Michael DeSalvo, Kelly Gómez-Campo, Susana Enríquez, Hiroaki Kitano, Rori Rohlfs, Roberto Iglesias-Prieto & Mónica Medina
As coral reefs struggle to survive under climate change, it is crucial to know whether they have the capacity to withstand changing conditions, particularly increasing seawater temperatures. Thermal tolerance requires the integrative response of the different components of the coral holobiont (coral host, algal photosymbiont, and associated microbiome). Here, using a controlled thermal stress experiment across three divergent Caribbean coral species, we attempt to dissect holobiont member metatranscriptome responses from coral taxa with different sensitivities...

Because of the different methods used to harvest tweets, there may be some duplication.

Gila Trout neutral and outlier SNP genotype matrices

David Camak, Megan Osborne & Thomas Turner
Many salmonid species exist in highly structured and isolated populations, and are susceptible to habitat fragmentation and disturbances. Gila Trout (Oncorhynchus gilae) is a threatened species found in the Southwestern United States, and is managed to preserve relict populations (i.e., lineages) distributed across a fragmented landscape. We evaluated genomic variation within and among remaining lineages of Gila Trout using RADseq to assess how drift and selection have structured populations using neutral and outlier loci. We...

A lightweight backpack harness for tracking hummingbirds

Jessie L. Williamson & Christopher C. Witt
Hummingbirds and other lightweight bird species are challenging to track because they have limited capacity to carry devices for data-logging. We present a simple and customizable three-loop ‘backpack’ harness for studying hummingbird migration and movement, with step-by-step instructions for harness construction and attachment. The harness has negligible weight and cost (< $0.50 USD/each), is easy for a single person to make and apply in the field, and it requires no complicated setup or equipment. We...

Contrasting patterns of phylogenetic diversity and alpine specialization across the alpine flora of the American mountain range system

Hector Fox Figueroa, Hannah E. Marx, Maria Beatriz De Souza Cortez, Charles J. Grady, Nicholas Engle-Wrye, Jim Beach, Aimee Stewart, Ryan A. Folk, Douglas E. Soltis, Pamela S. Soltis & Stephen A. Smith
Although mountainous habitats contribute substantially to global biodiversity, comparatively little is known about biogeographic patterns of distributions of alpine species across multiple mountain ranges. Here, we present a detailed analysis of the distributions and phylogenetic affinities of alpine seed plant lineages across North, Central, and South American mountain systems. Using a comprehensive dataset that characterized the elevational niches of American seed plants in a continuously valued way, we were able to quantitatively investigate how the...

Analysis of paralogs in target enrichment data pinpoints multiple ancient polyploidy events in Alchemilla s.l. (Rosaceae)

Diego F. Morales-Briones, Berit Gehrke, Chien-Hsun Huang, Aaron Liston, Hong Ma, Hannah Marx, David Tank & Ya Yang
Target enrichment is becoming increasingly popular for phylogenomic studies. Although baits for enrichment are typically designed to target single-copy genes, paralogs are often recovered with increased sequencing depth, sometimes from a significant proportion of loci, especially in groups experiencing whole-genome duplication (WGD) events. Common approaches for processing paralogs in target enrichment data sets include random selection, manual pruning, and mainly, the removal of entire genes that show any evidence of paralogy. These approaches are prone...

A revised classification of Glossopetalon (Crossosomataceae) based on restriction site-associated DNA sequencing

Maya Allen & Tina Ayers
Glossopetalon inhabits arid regions in the American west and northern Mexico on limestone substrates. The genus comprises four species: G. clokeyi ; G. pungens ; G. texense ; and G. spinescens . Three of the species are narrow endemics. The fourth, G. spinescens , is a widespread species with six recognized varieties. All six varieties are intricately branched shrubs that have been difficult to identify due to a lack of clearly delineating morphological characters. Characters...

Inter- and intra-archipelago dynamics of population structure and gene flow in a Polynesian bird

Ethan Gyllenhaal, Xena Mapel, Tejashree Modak, Lucas DeCicco, Alivereti Naikatini, Ruth Utzurrum, Joshua Seamon, Jean-Claude Thibault, Alice Cibois, Michael Sorenson, Robert Moyle, Lisa Barrow & Michael Andersen
Islands are separated by natural barriers that prevent gene flow between terrestrial populations and promote allopatric diversification. Birds in the South Pacific are an excellent model to explore the interplay between isolation and gene flow due to the region’s numerous archipelagos and well-characterized avian communities. The wattled honeyeater complex (Foulehaio spp.) comprises three allopatric species that are widespread and common across Fiji, Tonga, Samoa, and Wallis and Futuna. Here, we explored patterns of diversification within...

Plant traits and soil fertility mediate productivity losses under extreme drought in C3 grasslands

Wentao Luo, Robert Griffin-Nolan, Wang Ma, Bo Liu, Xiaoan Zuo, Chong Xu, Qiang Yu, Yahuang Luo, Pierre Mariotte, Melinda Smith, Scott Collins, Alan Knapp, Zhengwen Wang & Xingguo Han
Extreme drought decreases aboveground net primary production (ANPP) in most grasslands, but the magnitude of ANPP reductions varies especially in C3-dominated grasslands. Because the mechanisms underlying such differential ecosystem responses to drought are not well-resolved, we experimentally imposed an extreme 4-year drought (2015-2018) in two C3 grasslands that differed in aridity. These sites had similar annual precipitation and dominant grass species (Leymus chinensis) but different annual temperatures and thus water availability. Drought treatments differentially affected...

Limited evidence for a positive relationship between hybridization and diversification across seed plant families

Nora Mitchell & Kenneth Whitney
Hybridization has experimental and observational ties to evolutionary processes and outcomes such as adaptation, speciation, and radiation. Although it has been hypothesized that hybridization and diversification are positively correlated, this idea remains largely untested empirically, and hybridization can also potentially reduce diversity. Here, we use a hybridization database on 170 seed plant families, life history information, and a time-calibrated phylogeny to test for phylogenetically-corrected associations between hybridization and diversification rates, while also taking into account...

Supporting Data To: Shark tooth collagen stable isotopes (δ15N and δ13C) as ecological proxies

Oliver Shipley, Gregory Henkes, James Gelsleichter, Clark Morgan, Eric Schneider, Brendan Talwar & Michael Frisk
The isotopic composition of tooth-bound collagen has long been used to reconstruct dietary patterns of animals in extant and paleoecological systems. For sharks that replace teeth rapidly in a conveyor-like system, stable isotopes of tooth collagen (δ13Ctooth & δ15Ntooth) are poorly understood and lacking in ecological context relative to other non-lethally sampled tissues. This tissue holds promise, because shark jaws may preserve isotopic chronologies from which to infer individual-level ecological patterns across a range of...

Data from: Impact of antecedent soil moisture on runoff from a semiarid catchment

Gerhard Schoener & Mark C. Stone
Antecedent soil moisture is an important factor in the generation of runoff, but guidance for modeling moisture conditions in semiarid catchments is limited and conflicting. In this study, the impact of antecedent moisture was assessed at the plot scale (2.8 m2) using a portable rainfall simulator, and at the catchment scale based on observed precipitation and discharge for a 2.8 km2 watershed in central New Mexico. Performance of three loss models commonly used for hydrologic...

Data from: Monitoring soil moisture at the catchment scale – A novel approach combining antecedent precipitation index and radar-derived rainfall data

Gerhard Schoener & Mark C. Stone
Knowledge about soil moisture is important for event-based rainfall-runoff models but monitoring conditions at the catchment scale is not a trivial task. Soil moisture is highly variable in space and time, particularly in dry climates with seasonal and spatially heterogeneous rainfall. Point measurements are difficult to upscale, and remotely sensed (RS) data often lack in spatial or temporal resolution for local or regional studies. Longer latency periods – the time required before data becomes available...

Proximity to crop relatives determines patterns of natural selection in a wild sunflower

Nora Mitchell, Scott Chamberlain & Kenneth Whitney
Abiotic and biotic heterogeneity result in divergent patterns of natural selection in nature, with important consequences for fundamental evolutionary processes including local adaptation, speciation and diversification. However, increasing amounts of the global terrestrial surface are homogenized by agriculture (which covers nearly 50% of terrestrial vegetated land surface) and other anthropogenic activities. Agricultural intensification leads to highly simplified biotic communities for many taxa, which may alter natural selection through biotic selective agents. In particular, the presence...
