Introduction
I am a Visiting Associate Professor in the Faculty of Biology at the University of Latvia and an Assistant Professor at Otterbein University. My lab group uses phylogenetic and comparative genomic frameworks to address questions pertaining to the evolution of flowering plant lineages and their genomes.

Article
The drivers of angiosperm diversity have long been sought, and the flower-arthropod association has often been invoked as the most powerful driver of the angiosperm radiation. We now know that features that influence arthropod interactions can not only affect the diversification of lineages, but also expedite or constrain their rate of extinction,...

Premise of the study: As more plastomes are assembled, it is evident that rearrangements, losses, intergenic spacer expansion and contraction, and syntenic breaks within otherwise functioning plastids are more common than was thought previously, and such changes have developed independently in disparate lineages. However, to date, the magnoliids r...

The mitochondrial genomes (mitogenomes) of plants are known to incorporate and accumulate DNA from intra-and extracellular donors. Despite the intimate relationships formed between flowing plants (angiosperms) and fungi, lengthy fungal-like sequence has not been identified in angiosperm mitogenomes to date. Here we present multiple lines of evidenc...

The capability to generate densely sampled single nucleotide polymorphism (SNP) data is essential in diverse subdisciplines of biology, including crop breeding, pathology, forensics, forestry, ecology, evolution, and conservation. However, the wet‐lab expertise and bioinformatics training required to conduct genome‐scale variant discovery remain li...
Article
Full-text available
The nature and definition of species continue to be matters of debate. Current views of species often focus on their nature as lineages—maximal reproductive communities through time. Whereas many authors point to the Evolutionary Species Concept as optimal, in its original form it stressed the ecological role of species as well as their history as...
Preprint
Lineage-based species definitions applying coalescent approaches to species delimitation have become increasingly popular. Yet, the application of these methods and the recognition of lineage-only definitions have recently been questioned. Species delimitation criteria that explicitly consider both lineages and evidence for ecological ‘role’ shifts...
Article
Full-text available
Divergence in forelimb morphology is often associated with functional habits exhibited within the Xenarthra, ranging from terrestrial-digging in armadillos to arboreal-suspension in sloths. We hypothesized that quantitative differences in hind limb form also will be predictive of the diverse lifestyles observed in this small clade. A total of 26 mo...
Article
Mycoheterotrophic plants derive most or all carbon and nutrients from fungal partners and represent poorly understood components of forest biodiversity. Many are rare or endangered yet can be ecological indicators of forest ecosystem function due to fungal host requirements. One such species is the IUCN red-listed (“vulnerable”), fully mycoheterotr...
Article
Full-text available
Approximately two thirds of freshwater mussel species in the United States and Canada are imperiled, and populations are declining rapidly. Translocation and captive management are commonly used to mitigate losses of freshwater mussel biodiversity, but these conservation tools may result in decreased growth and increased mortality. This study uses...

Article
Full-text available
Hybridization and introgression are common processes among numerous plant species that present both challenges and opportunities for studies of species delimitation, phylogenetics, taxonomy and adaptation. Rhus integrifolia and R. ovata are two ecologically important shrubs native to the southwestern USA and Mexico, and are known to hybridize frequ...

Mycoheterotrophic plants derive most or all carbon and nutrients from fungal partners and represent poorly understood components of forest biodiversity. Many are rare or endangered yet can be ecological indicators of forest ecosystem function due to their often highly specific fungal host requirements. One such species is the IUCN red-listed (vulne...
Article
Full-text available
Background: Plastid gene loss and pseudogenization has been widely documented in parasitic and mycoheterotrophic plants, which have relaxed selective constraints on photosynthetic function. More enigmatic are sporadic reports of pseudogenization and loss of important photosynthesis genes in lineages thought to be fully photosynthetic. Here we repo...

Heterotrophic plants are evolutionary experiments in genomic, morphological, and physiological change. Yet, genomic sampling gaps exist among independently derived heterotrophic lineages, leaving unanswered questions about the process of genome modification. Here, we have sequenced complete plastid genomes for all species of the leafless orchid gen...
Article
Full-text available
Mechanisms of genome evolution are fundamental to our understanding of adaptation and the generation and maintenance of biodiversity, yet genome dynamics are still poorly characterized in many clades. Strong correlations between variation in genomic attributes and species diversity across the plant tree of life suggest that polyploidy or other mech...

Slow rates of molecular evolution at low taxonomic levels hamper studies of relationships among species and subsequent biogeographic and evolutionary analyses. An example is the genus Brahea, which is among the most poorly understood lineages of American palms and is characterized by a wide variety of growth forms and intermediate morphological fea...

High-throughput sequencing technologies, such as RNA sequencing (RNA-Seq), have greatly enhanced our ability to sequence and characterize the transcriptome of nonmodel organisms. The ability to study expression of thousands of genes in highly threatened yet understudied organisms holds great potential for advancing the field of conservation biology...

The Planteome project (http://www.planteome.org) provides a suite of reference and species-specific ontologies for plants and annotations to genes and phenotypes. Ontologies serve as common standards for semantic integration of a large and growing corpus of plant genomics, phenomics and genetics data. The reference ontologies include the Plant Onto...

Hundreds of years of botanical exploration in heavily populated and highly accessible eastern North America have not exhausted taxonomic prospects in the region. Here, I describe a new species of Asarum (Aristolochiaceae), Asarum rosei B.T.Sinn, from North Carolina, USA. This species is characterized and contrasted with species in Asarum subgenus H...
Article
The forests of eastern North America continue to yield new species, despite more than 200 years of botanical exploration. As a result of fieldwork conducted from 2012 - 2014, a new Asarum (Aristolochiaceae) species was found in the foothills of the Blue Ridge Mountains of Tennessee and Virginia. This species, A. chueyi, is here distinguished from o...
Article
Premise of the study: Generic boundaries and infrageneric relationships among the charismatic temperate magnoliid Asarum sensu lato (Aristolochiaceae) have long been uncertain. Previous molecular phylogenetic analyses used either plastid or nuclear loci alone and varied greatly in their taxonomic implications for the genus. We analyzed additional m...
