Deep ancestral introgression shapes evolutionary history of dragonflies and damselflies

Anton Suvorov, Celine Scornavacca, M. Stanley Fujimoto, Paul Bodily, Mark Clement, Keith Crandall, Michael Whiting, Daniel Schrider & Seth Bybee
Introgression is arguably one of the most important biological processes in the evolution of groups of related species, affecting at least 10% of the extant species in the animal kingdom. Introgression reduces genetic divergence between species, and in some cases can be highly beneficial, facilitating rapid adaptation to ever-changing environmental pressures. Introgression also significantly impacts inference of phylogenetic species relationships where a strictly binary tree model cannot adequately explain reticulate net-like species relationships. Here we...

Data from: Ontogenetic shape trajectory of Trichomycterus areolatus varies in response to water velocity environment

Peter Searle, Margaret Mercer, Evelyn Habit & Mark Belk
Body and head shape among fishes both vary between environments influenced by water velocity and across ontogeny. Although the shape changes associated with variation in average water velocity and ontogeny are well documented, few studies have tested for the interaction between these two variables (i.e., does ontogenetic shape variation differ between velocity environments). We use geometric morphometrics to characterize shape differences in Trichomycterus areolatus, a freshwater catfish found in high and low-velocity environments in Chile....

No evidence for increased fitness of offspring from multigenerational effects of parental size or natal carcass size in the burying beetle Nicrophorus marginatus

Mark Belk, Ethan Damron, Ashlee Momcilovitch & Dane Jo
Multigenerational effects (often called maternal effects) are components of the offspring phenotype that result from the parental phenotype and the parental environment as opposed to heritable genetic effects. Multigenerational effects are widespread in nature and are often studied because of their potentially important effects on offspring traits. Although multigenerational effects are commonly observed, few studies have addressed whether they affect offspring fitness. In this study we assess the effect of potential multigenerational effects of parental...

Molecular evolution of phototransduction pathway genes in nocturnal and diurnal fireflies (Coleoptera: Lampyridae)

Gavin Martin, Sarah Lower, Anton Suvorov & Seth Bybee
Most organisms are dependent on sensory cues from their environment for survival and reproduction. Fireflies (Coleoptera: Lampyridae) represent an ideal system for studying sensory niche adaptation due to many species relying on bioluminescent communication, as well as a diversity of ecology. Here we examine the phototransduction pathway in this non-model organism, and provide some of the first evidence for positive selection in the PT pathway in insects. Duplications are found in calmodulin, inactivation no afterpotential...

Carpophiline-ID: An interactive matrix-based key to the carpophiline sap beetles (Coleoptera, Nitidulidae) of Eastern North America

Courtney DiLorenzo, Gareth Powell, Andrew Cline & Joseph McHugh
We present Carpophiline-ID, a matrix-based LucidTM key, for the adult stage of the known species of Carpophilinae (Coleoptera: Nitidulidae) of North America, east of the Mississippi River. We provide an overview of the features and technical specifications used to build the key. The list of terminal taxa used in the key represents the most current regional account for Carpophilinae, a beetle subfamily of agricultural and ecological importance. We discuss the value of matrix-based, free access...

Summer land surface temperature from MODIS Aqua and Terra satellites for Houston in 2014 and Phoenix in 2003 at 1km resolution

Gavin Collins, Leiqiu Hu & Matthew Heaton
Satellite remote-sensing is used to collect important atmospheric and geophysical data at various spatial resolutions, providing insight into spatiotemporal surface and climate variability globally. These observations are often plagued with missing spatial and temporal information of Earth’s surface due to (1) cloud cover at the time of a satellite passing and (2) infrequent passing of polar-orbiting satellites. While many methods are available to model missing data in space and time, in the case of land...

Herbicide effects on the establishment of a native bunchgrass in annual grass invaded areas: Indaziflam vs. imazapic

Tyson Terry, Matthew Madsen, Samuel St Clair, Val Anderson & Richard Gill
Annual grass invasion is transforming the western US and driving a need for restoration techniques that can both reduce exotic annual grass abundance and allow revegetation of native species. Pre-emergent herbicides can provide control of annual grasses, but when applied concurrently with direct seeding efforts, the herbicide can also impact seeded species. Indaziflam is a relatively new herbicide that may provide extended control of exotic annual grasses, but little is known about its effects when...

Nematode parasites of rockfish (Sebastes spp.) and cod (Gadus spp.) from waters near Kodiak Island Alaska, USA

Mark Belk, Mehmet Oguz, Samuel Bennett & Andrea Campbell
Distribution and abundance of common parasitic nematodes in marine fishes is not well documented in many geographic regions. Understanding the influence of large-scale environmental changes on infection rates of fish by nematodes requires quantitative assessments of parasite abundance for multiple host species. We collected samples of two species of cod and eight species of rockfish (total of 232 specimens) from waters near Kodiak Island, Alaska, USA during Spring and Summer of 2015, and dissected and...

Episodic occurrence of favorable weather constrains recovery of a cold desert shrubland after fire

Alexandra Urza, Peter Weisberg, David Board, Jeanne Chambers, Stanley Kitchen & Bruce Roundy
1. Key to the long-term resilience of dryland ecosystems is the recovery of foundation plant species following disturbance. In ecosystems with high interannual weather variability, understanding the influence of short-term environmental conditions on establishment of foundation species is essential for identifying vulnerable landscapes and developing restoration strategies. We asked how annual environmental conditions affect post-fire establishment of Artemisia tridentata, a shrub species that dominates landscapes across much of the western United States, and evaluated the...

Data from: Species boundaries in the messy middle – testing the hypothesis of micro-endemism in a recently diverged lineage of coastal fog desert lichen fungi

Steven Leavitt
Species delimitation among closely related species is challenging because traditional phenotype-based approaches, e.g., morphology, ecological, or chemical characteristics, often produce conflicting results. With the advent of high-throughput sequencing, it has become increasingly cost-effective to acquire genome-scale data which can resolve previously ambiguous species boundaries. As the availability of genome-scale data has increased, numerous species delimitation analyses, such as BPP and SNAPP+Bayes factor delimitation (BFD*), have been developed to delimit species boundaries. However, even empirical molecular...

Life history and location data for Alfaro cultratus in 20 localities

Kaitlyn Golden, Mark Belk & Jerald Johnson
Predation is known to have a significant effect on life history diversification in a variety of species. However, physical constraints of body shape and size can sometimes limit life history divergence. We test this idea in the Costa Rican livebearing fish Alfaro cultratus. Individuals in this species have a narrow body and keeled ventral surface, and females do not develop a distended abdomen when pregnant like other livebearing fishes. Here, we describe the life history...

Target enrichment sequence data of Odonata, supporting Bybee et al. 2021

Seth Bybee
Dragonflies and damselflies are a charismatic, medium-sized insect order (~6300 species) with a unique potential to approach comparative research questions. Their taxonomy and many ecological traits for a large fraction of extant species are relatively well understood. However, until now, the lack of a large-scale phylogeny based on high throughput data with the potential to connect both perspectives has precluded comparative evolutionary questions for these insects. Here, we provide an ordinal hypothesis of classification based...

Cooperative communication with humans evolved to emerge early in domestic dogs

Hannah Salomons, Kyle C.M. Smith, Megan Callahan-Beckel, Margaret Callahan, Kerinne Levy, Brenda S. Kennedy, Emily E. Bray, Gitanjali E. Gnanadesikan, Daniel J. Horschler, Margaret Gruen, Jingzhi Tan, Philip White, Bridgett M. VonHoldt, Evan L. MacLean & Brian Hare
While we know that dogs evolved from wolves, it remains unclear how domestication affected dog cognition. One hypothesis suggests dog domestication altered social maturation by a process of selecting for an attraction to humans. Under this account, dogs became more flexible in using inherited skills to cooperatively-communicate with a new social partner that was previously feared and expressed these unusual social skills early in development. Here we tested dog (N=44) and wolf (N=37) puppies, 5-18...

Size matters, but species do not: no evidence for species-specific swimming performance in co-occurring Great Basin stream fishes

Mark Belk, Rollin Hotchkiss, Russell Rader, John Aedo & Keith Otto
For fishes, swimming performance is an important predictor of habitat use and a critical measure for the design of effective fish passage systems. Few studies have examined burst and prolonged types of swimming performance among several co-occurring species, and swimming performance in many fish communities is undocumented. In this study, we characterize both burst (c-start velocity) and prolonged speed (critical swim speed) across a poorly documented, co-occurring group of stream fishes within the Great Basin...
