Taxonomy of arbuscular mycorrhizal fungi (AMF) fungi (Glomeromycota) has long relied on spore morphological characteristics, which are distinguishable and evolutionarily stable structures in these fungi. Mode of spore formation and germination properties in AMF identify higher order taxa. Species level traits include external and internal spore morphology ( e.g. size, color, spore wall structure, surface ornamentation) and som...
Impacts of Quaternary Climate History on the Biogeography of Specialized Butterflies in the Great Basin of North AmericaNARA Subscribed
Aim Dramatic Quaternary climate fluctuations impacted the evolutionary history and contemporary biogeography of many residents of the Great Basin Desert of western North America. This study investigates the historical biogeographic processes that shaped the contemporary distribution of genetic variation in a polytypic group of specialized butterflies that are residents of unique dune and playa habitats. Many of the subspecies...
Leptospira interrogans serovar Pomona infections cause periodic outbreaks in California sea lions (CSLs; Zalophus californianus ) and sporadic deaths in phocids. However, the frequency of infection and associated health impacts remain uncharacterized in sympatric threatened southern sea otters (SSOs; Enhydra lutris nereis ), which serve as important sentinels of coastal health. Given the broad impacts of L. interrogans on othe...
Analyses of gene expression in the skin of several species of whales have identified genes that are differentially expressed in association with environmental factors, suggesting that skin transcriptomics may provide a valuable tool for assessing physiological responses in marine mammals. Previous work exploring differing levels of gene expression has focused on odontocetes, with comparatively limited investigation of skin gen...
