“…We examine population genetic structure and functional connectivity among populations of a declining species, the Blainville's horned lizard (Phrynosoma blainvillii), in the urbanized landscape of the Greater Los Angeles Area in Southern California, USA. Using single nucleotide polymorphism data, we assessed genetic structure among populations occurring at the interface of two abutting evolutionary lineages, and at a fine scale among habitat fragments within the heavily urbanized area. …”

“…Here, high‐frequency (daily) changes in relative abundance dynamics of the metabolically active protistan community were followed via expressed 18S V4 rRNA genes (RNA) throughout two algal blooms during the spring of 2018 and 2019 in Santa Monica Bay (central Southern California Bight). A diatom bloom formed after wind‐driven, nutrient upwelling events in both years, but different taxa dominated each year. …”

“…We quantified the levels of A. m. scutellata ancestry in colonies and conducted a seasonal assessment (May through November) of colony nest defensiveness in feral scutellata-hybrid and a popular lineage of European honey bee commonly used in managed environments (sold as A. mellifera ligustica) hives at two apiaries in Southern California. Standard measures of defensiveness were low in both scutellata-hybrid and European colonies during May. …”

“…• Premise of the study: Microsatellite (simple sequence repeat [SSR]) markers were developed for Ceanothus megacarpus, a chaparral species endemic to coastal southern California, to investigate potential processes (e.g., fragmentation, genetic drift, and interspecific hybridization) responsible for the genetic structure within and among populations distributed throughout mainland and island populations. • Methods and Results: Four SSR-enriched libraries were used to develop and optimize 10 primer sets of microsatellite loci containing either di-, tri-, or tetranucleotide repeats. …”
