The nature and definition of species continue to be matters debate. Current views often focus on their as lineages-maximal reproductive communities through time. Whereas many authors point the Evolutionary Species Concept optimal, in its original form it stressed ecological role well history lineages, but most recent have ignored aspect concept, making difficult apply unambiguously a time-extended way. This trend has been exacerbated by application methods concepts emphasizing notion...
Cnidarians represent one of the few groups venomous animals that lack a centralized venom transmission system. Instead, they are equipped with stinging capsules collectively known as nematocysts. Nematocysts vary in abundance and type across different tissues; however, composition most species remains unknown. Depending on tissue type, sea anemones may be vital for predation, defense, or digestion. Using tissue-specific RNA-seq approach, we characterize assemblage tentacles, mesenterial...
Venom is a key adaptive innovation in snakes, and how nonvenom genes were co-opted to become part of the toxin arsenal significant evolutionary question. While this process has been investigated through phylogenetic reconstruction sequences, evidence provided by genomic context remains less explored. To investigate recruitment, we sequenced genome
Ericaceae (the heather family) is a large and diverse group of plants that forms elaborate symbiotic relationships with mycorrhizal fungi, includes several nonphotosynthetic lineages. Using an extensive sample fully mycoheterotrophic (MH) species, we explored inter- intraspecific variation as well selective constraints acting on the plastomes these unusual plants. The seven MH genera were analysed in phylogenetic context two geographically disparate individuals sequenced for Allotropa,...
Abstract Relicanthus daphneae (formerly Boloceroides ) was first described in 2006 as a giant sea anemone based on morphology. In 2014, its classification challenged molecular data: using five genes, resolved sister to zoanthideans, but with mixed support. To better understand the evolutionary relationship of other early-branching metazoans, we present 15 newly-sequenced mitochondrial genomes and mitogenome-based phylogeny including all major cnidarian groups, sponges, placozoans. Our...
Abstract Sequences and structural attributes of mitochondrial genomes have played a critical role in the clarification relationships among Cnidaria, key phylum early-diverging animals. Among major lineages Ceriantharia (“tube anemones”) remains one most enigmatic terms its phylogenetic position. We sequenced two ceriantharians to see whether complete organellar genome would provide more support for placement Ceriantharia. For both Isarachnanthus nocturnus Pachycerianthus magnus , gene...
Abstract The relationships among pyroloids, monotropoids, arbutoids and the remainder of Ericaceae continue to be unresolved even though significant progress has been made in understanding phylogenetic structure family. This means that, addition uncertainty classification, evolutionary patterns vegetative mycorrhizal diversity family have also uncertain. study analyzes nuclear, plastid mitochondrial sequence data order provide a basis for classification character analysis. Parsimony maximum...
Abstract— Monotropoideae (Ericaceae) is a wholly leafless and holomycotrophic group of primarily temperate herbs with centers diversity in western North America east Asia. The eleven genera are structurally diverse also vegetatively reduced, making relationships difficult to assess based on morphology. Previous molecular analyses have focused segments the ribosomal RNA repeat yielded sometimes conflicting topologies. We employed genomic sampling approach obtain 102 nuclear loci plastid...
An important goal of conservation genetics is to determine if the viability small populations reduced by a loss adaptive variation due genetic drift. Here, we assessed impact drift and selection on direct measures (toxin loci encoding venom proteins) in eastern massasauga rattlesnake (Sistrurus catenatus), threatened reptile that exists isolated populations. We estimated levels individual polymorphism 46 toxin 1,467 control across 12 this species, compared results with patterns same...
Abstract The taxonomy of North American crayfishes has recently experienced a boom in interest as these crustaceans have become increasingly imperiled. Improving taxonomic resolution can inform and facilitate conservation efforts but proven challenging for due to the limited number molecular tools available resolve species complexes delimit species. burrowing crayfish LacunicambarusHobbs, 1969 particularly convoluted history that epitomizes many challenges taxonomy.

Abstract— Relationships among members of Ericaceae subfamily Monotropoideae have been difficult to resolve due reduction and convergent evolution in these parasitic plants. All species this are fully mycoheterotrophic, meaning they obtain nutrients by parasitizing fungi rather than through photosynthesis. Here, we examine relationships host specificity one the most widespread subfamily, Monotropa uniflora . We use several lines evidence investigate whether there is support for recognizing a...
