Dire wolves (Aenocyon dirus) are extinct predators of Pleistocene North America. Although phenotypically similar to living (Canis lupus), dire have yet be placed confidently in the canid family tree. We generated 3.4x and 12.8x paleogenomes from two well-preserved dating > 13,000 72,000 years ago, estimated consensus species trees for these 10 species. Our results revealed that ~2/3 wolf ancestry is derived a lineage sister clade comprising gray wolf, coyote, dhole, remaining ~1/3 near...
Most herbivorous insect species are restricted to a narrow taxonomic range of host plant species. Herbivore that feed on mustard plants and their relatives in the Brassicales have evolved highly efficient detoxification mechanisms actually prevent toxic oils from forming bodies animals. However, these likely were not present during initial stages specialization ~100 million years ago. The fly Scaptomyza nigrita (Drosophilidae) is specialist single species, bittercress (Cardamine cordifolia;...
Parasites are among the most diverse groups of life on Earth, yet complex natural histories often preclude studies their speciation processes. The biology parasitic plants facilitates in situ collection data both genetic structure and mechanisms responsible for that structure. Here, we studied role mating, dispersal establishment host race formation a plant. We investigated population genetics vector-borne desert mistletoe (Phoradendron californicum) across two legume tree species (Senegalia...
Plant distributions can be limited by habitat-biased herbivory, but the proximate causes of such biases are rarely known. Distinguishing plant-centric from herbivore-centric mechanisms driving differential herbivory between habitats is difficult without experimental manipulation both plants and herbivores. Here we tested alternative hypotheses in bittercress (Cardamine cordifolia), which more abundant under shade shrubs trees (shade) than nearby meadows (sun) where intense specialist fly...
Among the three domains of life, process homologous recombination (HR) plays a central role in repair double-strand DNA breaks and restart stalled replication forks. Curiously, main protein actors involved HR appear to be essential for hyperthermophilic Archaea raising interesting questions about strategies those living extreme conditions. One key actor this is recombinase RadA, which allows strand search provides substrate required following synthesis restoring genetic information....
North American minnows (Cypriniformes: Leuciscidae) comprise a diverse taxonomic group, but many members, particularly those inhabiting deserts, face elevated extinction risks. Despite conservation concerns, leuciscids remain under sampled for reference assemblies relative to other groups of freshwater fishes. Here, we present 2 chromosome-scale genome spikedace (Meda fulgida) and loach minnow (Tiaroga cobitis) using PacBio, Illumina Omni-C technologies. The complete assembly was 882.1 Mb in...

The American black bear, Ursus americanus, is a widespread and ecologically important species in North America. In California, the bear plays an role variety of ecosystems serves as for recreational hunting. While research suggests that populations California are currently healthy, continued monitoring critical, with genomic analyses providing surveillance tool. Here we report high-quality, near chromosome-level genome assembly from U. americanus sample California. primary has total length...
Great apes have maintained a stable karyotype with few large-scale rearrangements; in contrast, gibbons undergone high rate of chromosomal rearrangements coincident rapid centromere turnover. Here we characterize assembled centromeres the Eastern hoolock gibbon,
Abstract Mountain lions, Puma concolor, are widespread and adaptable carnivores. However, due to their large home ranges long distance dispersals, they strongly impacted by habitat fragmentation, which results in small isolated populations. Genomic analyses play an important role understanding predicting the impacts of increased isolation populations, such as decreased genetic diversity levels inbreeding. Here we report a high-quality, chromosome-level reference genome P. concolor that was...

For agriculturally important plants, pollination and herbivory are two ecological factors that play into the success of crop yields. Each is also in natural environments where invasive plants their effect on species interactions may alter native ecology. The California Wild Radish (Raphanus sativus x raphanistrum), a hybrid derived from an nonnative cultivar, common California. Remarkably, it has recently replaced wild populations both progenitor species. Experiments phenotypic variation for...
