Phylogenomics resolves the relationships within Antennaria (Asteraceae, Gnaphalieae) and yields new insights into its morphological character evolution and biogeography

Ramhari Thapa, Randall Bayer & Jennifer Mandel
Antennaria are dioecious perennial herbs distributed mainly in the Holarctic Region with their major center of diversity in the Rocky Mountains of Western North America. The genus comprises 33 known sexual diploid/tetraploid species and at least five polyploid agamic complexes which mostly reproduce by forming asexual seeds. We performed a phylogenetic reconstruction of the 31 sexually-reproducing Antennaria species using a novel target enrichment method that employs custom capture probes and is designed to work across...

Data from: Distribution and biogeography of Sanguina snow algae: fine-scale sequence analyses reveal previously unknown population structure

Shawn Brown
It has been previously suggested that snow algal species within the genus Sanguina (S. nivaloides and S. aurantia) show no population structure despite being found globally (S. nivaloides) or throughout the Northern Hemisphere (S. aurantia). However, systematic biogeographic research into global distributions is lacking due to few genetic and no genomic resources for these snow algae. Here, using all publicly available and previously unpublished Sanguina sequences of the Internal Transcribed Spacer 2 region, we investigate...

Phylogenomic analysis sheds light on the evolutionary pathways towards acoustic communication in Orthoptera

Hojun Song, Olivier Béthoux, Seunggwan Shin, Alexander Donath, Harald Letsch, Shanlin Liu, Duane D. McKenna, Guanliang Meng, Bernhard Misof, Lars Podsiadlowski, Xin Zhou, Benjamin Wipfler & Sabrina Simon
Acoustic communication is enabled by the evolution of specialised hearing and sound producing organs. In this study, we performed a large-scale macroevolutionary study to understand how both hearing and sound production evolved and affected diversification in the insect order Orthoptera, which includes many familiar singing insects, such as crickets, katydids, and grasshoppers. Using phylogenomic data, we firmly establish phylogenetic relationships among the major lineages and divergence time estimates within Orthoptera, as well as the lineage-specific...

Phylogenomic data for hyperdiverse daisy tribes

Jennifer Mandel, Linda Watson & Carolina Siniscalchi
Asteraceae account for 10% of all flowering plant species, and 35-40% of these are in five closely-related tribes that total over 10,000 species. These tribes include Anthemideae, Astereae, Calenduleae, Gnaphalieae, and Senecioneae, which form one of two enormous clades within Subfamily Asteroideae. We took a phylogenomics approach to resolve evolutionary relationships among these five tribes. We sampled the nuclear and plastid genomes via HybSeq target enrichment and genome skimming, and recovered 74 plastid genes and...

Data from: Anthelmintic drugs modulate the acute phase immune response but not the microbiota in wild Song Sparrows

Grace Vaziri, Michelle Jusino, Jon Palmer, Matthew Brewer & James Adelman
Co-infection with microparasites (e.g., bacteria) and macroparasites (e.g., helminths) is often the natural state for wild animals. Despite evidence that gut helminths can bias immune responses away from inflammatory processes, few field studies have examined the role that helminths, or their potential interactions with internal microbial communities, play in modulating immunity in free-living, wild birds. Here, we used anthelmintic drugs to treat wild Song Sparrows (Melospiza melodia) for helminth infections and measured markers of systemic...

Variation in brown rat cranial shape shows directional selection over 120 years in New York City

Emily Puckett, Emma Sherratt, Matthew Combs, Elizabeth Carlen, William Harcourt-Smith & Jason Munshi-South
Urbanization exposes species to novel environments and selection pressures that may change morphological traits within a population. We investigated how the shape and size of crania and mandibles changed over time within a population of brown rats (Rattus norvegicus) living in Manhattan, New York, USA, a highly urbanized environment. We measured 3D landmarks on the cranium and mandible of 62 adult individuals sampled in the 1890s and 2010s. Static allometry explained approximately 22% of shape...

Bergmann's rule is followed at multiple stages of post-embryonic development in a long-distance migratory songbird

Joseph Youtz, Kelly Miller, Emerson Bowers, Samantha Rogers, Lesley Bulluck, Matthew Johnson, Brian Peer, Katie Percy, Erik Johnson, Elizabeth Ames, Christopher Tonra & Than Boves
Aim: We assessed the presence of Bergmann’s rule in a model migratory species across all life stages on their breeding grounds. We then compared historic and contemporary egg sizes to understand if the biogeographic patterns during this developmental life stage have changed over time. Location: Eastern North America. Time period: 1865 to 2019. Major taxa: Prothonotary warbler, Protonotaria citrea Methods: We measured the size of eggs, young and old nestlings, and adults (of two age...
