Diversification in the Rosales is influenced by dispersal, geographic range size, and pre-existing species richness

Andrew Simpson, Scott Wing & Charles Fenster
Biodiversity results from origination and extinction; thus there is interest in determining those traits that influence this balance. Among traits implicated in the success or failure of lineages are dispersal, colonization ability, and geographic range size. We investigate the impact of dispersal and range size on contemporary diversity in the order Rosales. We use the MuSSE method to explore the effects on genus-level diversification of two genus-level traits (geographic range size and within-genus proclivity to...

The rediscovery of a relict unlocks the first global phylogeny of whip spiders (Amblypygi)

Gustavo De Miranda, Siddharth Kulkarni, Jessica Tagliatela, Caitlin Baker, Alessandro P.L. Giupponi, Facundo Labarque, Efrat Gavish-Regev, Michael Rix, Leonardo Carvalho, Livia Fusari, Hannah Wood & Prashant Sharma
Asymmetrical rates of cladogenesis and extinction abound in the Tree of Life, resulting in numerous minute clades that are dwarfed by larger sister groups. Such taxa are commonly regarded as phylogenetic relicts or “living fossils” when they exhibit an ancient first appearance in the fossil record and prolonged external morphological stasis, particularly in comparison to their more diversified sister groups. Due to their special status, various phylogenetic relicts tend to be well-studied and prioritized for...

Broderick, Ignacio Bruno, Ali Fuat Canbolat, Paolo Casale, Daniel Cejudo, Michael S. Coyne, Corrie Curtice, Sarah DeLand, Andrew DiMatteo, Kara Dodge, Daniel C. Dunn, Nicole Esteban, Angela Formia, Mariana M. P. B. Fuentes, Ei Fujioka, Julie Garnier, Matthew H. Godfrey … & Patrick N. Halpin
Aim: Understanding the spatial ecology of animal movements is a critical element in conserving long-lived, highly mobile marine species. Analysing networks developed from movements of six sea turtle species reveals marine connectivity and can help prioritize conservation efforts. Location: Global. Methods: We collated telemetry data from 1,235 individuals and reviewed the literature to determine our dataset’s representativeness. We used the telemetry data to develop spatial networks at different scales to examine areas, connections, and their...

Strong migratory connectivity indicates Willets need subspecies-specific conservation strategies

Allison Huysman, Nathan Cooper, Joseph Smith, Susan Haig, Susan Heath, Luanne Johnson, Elizabeth Olson, Kevin Regan, Jennifer Wilson & Peter Marra
By combining all available banding and tracking data, we found that Willets (Tringa semipalmata) have strong migratory connectivity between breeding and nonbreeding locations at the range-wide and subspecies levels, exposing the two subspecies to varying threats such as hunting for the eastern subspecies (T. s. semipalmata) and climatically-altered coastal habitats for both subspecies. We found that Western Willets (T. s. inornata) primarily used nonbreeding habitats along the Pacific Coast of the United States, although their...

Lack of avian predators is associated with behavioural plasticity in nest construction and height in an island songbird

Rebecca Cheek, Sarah Hays, James Mouton, Scott Sillett & Cameron Ghalambor
Orange-crowned warblers, Leiothlypis celata sordida, breeding on the California Channel Islands exhibit remarkable variation in their nest structure and placement, providing an intriguing exception to the general pattern that avian nest structure and nest site selection are highly conserved characters. We examined nest construction at both the population and individual scale to test whether warblers on Santa Catalina Island change their nest construction in response to nest height. At the population level, warblers built both...

Phylogenomics suggests that larvae are ancestral in polyclads, but not homologous to the trochophore

Jessica Goodheart, Allen Collins, Michael Cummings, Bernhard Egger & Kate Rawlinson
Platyhelminthes (flatworms) are a diverse invertebrate phylum that are useful for exploring life history evolution. Within Platyhelminthes, only two clades develop through a larval stage: free-living polyclads and parasitic neodermatans. Neodermatan larvae are considered evolutionarily derived, whereas polyclad larvae are hypothesized to be retained from the last common ancestor of Platyhelminthes – and Spiralia – due to ciliary band similarities among polyclad and other spiralian larvae. However, larval evolution has been challenging to investigate within...

U.S. freshwater mussel occurrence data

John Pfeiffer, Traci Dubose & Sean Keogh
Natural history collections are uniquely positioned to chronicle biodiversity changes across time and space and are a fundamental data source in taxon-based research and conservation. With over 90 species listed under the Endangered Species Act, freshwater mussels are one of the most imperiled animal assemblages in the United States and are the focus of considerable conservation efforts (e.g., species status assessments, listing decisions, and recovery plans). Unfortunately, natural history collections data is often underleveraged in...

Data from: Floral evolution and pollinator diversification in Hedychium: revisiting Darwin’s predictions using an integrative taxonomic approach

Ajith Ashokan, Jana Leong-Škorničková, Piyakaset Suksathan, Mark Newman, W. John Kress & Vinita Gowda
Hedychium J.Koenig (Zingiberaceae) is endemic to the Indo-Malayan Realm and is known for its vibrant and fragrant flowers. Historically, two different pollination syndromes characterize Hedychium: diurnal or bird pollination and nocturnal or moth pollination. In this study we aim to understand the evolution of nocturnal and diurnal flowers, and to test its putative association with lineage diversification in Hedychium. A molecular tree of Hedychium was used as a scaffold upon which we estimated ancestral character-states,...

Data from: Exploring conflicts in whole genome phylogenetics: A case study within Manakins (Aves: Pipridae)

Min Zhao, Sarah Kurtis, Noor White, Andre Moncrieff, Rafael Leite, Robb Brumfield, Edward Braun & Rebecca Kimball
Some phylogenetic problems remain unresolved even when large amounts of sequence data are analyzed and methods that accommodate processes such as incomplete lineage sorting are employed. In addition to investigating biological sources of phylogenetic incongruence, it is also important to reduce noise in the phylogenomic dataset by using an appropriate filtering approach that addresses gene tree estimation errors. We present the results of a case study in manakins, focusing on the very difficult clade comprising...

Examining the diversity, stability, and functioning of marine fish communities across a latitudinal gradient

Helen Yan, Jordan Casey, Nancy Knowlton, J. Emmett Duffy & Simon Brandl
Aim: As anthropogenic stressors on the biosphere intensify, understanding how communities respond to disturbances is critical. Biodiversity is often thought to promote the stability of communities over time and enhance ecosystem functioning. However, results have been inconsistent, and the multifaceted linkages among diversity, stability, and functioning under acute disturbances remain poorly understood. We experimentally tested the responses of marine fish communities to disturbance (i.e., acute habitat loss) across a diversity gradient spanning 35º degrees of...

Increasing morphological disparity and decreasing optimality for jaw speed and strength during the radiation of jawed vertebrates

William Deakin, Philip Anderson, Wendy Den Boer, Thomas Smith, Jennifer Hill, Martin Rücklin, Philip Donoghue & Emily Rayfield
The Siluro-Devonian adaptive radiation of jawed vertebrates, which underpins almost all living vertebrate biodiversity, is characterised by the evolutionary innovation of the lower jaw. Multiple lines of evidence have suggested that the jaw evolved from a rostral gill arch, but when the jaw took on a feeding function remains unclear. We quantified the variety of form in the earliest jaws in the fossil record and , from which we generated a range of theoretical morphospacelogies...

Stabilized morphological evolution of spiders despite mosaic changes in foraging ecology

Jonas Wolff, Kaja Wierucka, Jonathan Coddington, Gustavo Hormiga, Michael Kelly, Marie Herberstein, Martín Ramírez & Gustavo Paterno
A prominent question in animal research is how the evolution of morphology and ecology interact in the generation of phenotypic diversity. Spiders are some of the most abundant arthropod predators in terrestrial ecosystems and exhibit a diversity of foraging styles. It remains unclear how spider body size and proportions relate to foraging style, and if the use of webs as prey capture devices correlates with changes in body characteristics. Here we present the most extensive...

Sexual signals persist over deep time: ancient co-option of bioluminescence for courtship displays in cypridinid ostracods

Emily Ellis, Jessica Goodheart, Nicholai Hensley, Vanessa González, Nicholas Reda, Trevor Rivers, James Morin, Elizabeth Torres, Gretchen Gerrish & Todd Oakley
Although the diversity, beauty, and intricacy of sexually selected courtship displays command the attention of evolutionists, the longevity of these traits in deep time is poorly understood. Population-based theory suggests sexual selection could either lower or raise extinction risk, resulting in high or low persistence of lineages with sexually selected traits. Furthermore, empirical studies that directly estimate longevity of sexually selected traits are uncommon. Sexually selected signals - including bioluminescent courtship - originated multiple times...

Evolutionary history constrains heat tolerance of native and exotic tropical Zingiberales

Georgia G. Hernández, Timothy M. Perez, Oscar M. Vargas, W. John Kress, Ramón Molina-Bravo, Roberto A. Cordero & Carlos García-Robledo
Tropical wet forest plants experience relatively stable temperatures throughout the year. However, tropical forests represent a mosaic of habitats characterized by different temperatures. Heat tolerances are expected to be adapted to temperatures specific to their habitats. Although the heat tolerance of species sharing similar environments is expected to be similar, it is also possible that heat tolerance is constrained by evolutionary history because closely related species usually display similar physiologies. When exotic species are introduced...
