3 Beckerle, Mary C.; Clark, Kathleen A.Integrin effector PINCH regulates JNK activity and epithelial migration in concert with Ras suppressor 1Cell adhesion and migration are dynamic pro- cesses requiring the coordinated action of multiple signaling pathways, but the mechanisms underlying signal integration have remained elusive. Drosophila embryonic dorsal closure (DC) requires both integrin function and c-Jun amino-terminal kinase (JNK) ...Epithelial sheets; PINCH2004
4 Clayton, Dale H.Ecological basis of coevolutionary historyMacroevolutionary patterns are difficult to interpret because they are the product of a time scale so vast that deterministic and chance events are hard to distinguish. Although the macroevolutionary history of a group can be reconstructed from extant species, determining the ecological context in ...2003
5 Clayton, Dale H.; Rogers, Alan R.Genetic analysis of lice supports direct contact between modern and archaic humansParasites can be used as unique markers to investigate host evolutionary history, independent of host data. Here we show that modern human head lice, Pediculus humanus, are composed of two ancient lineages, whose origin predates modern Homo sapiens by an order of magnitude (ca. 1.18 million years).Pediculus humanus; Head lice; Molecular phylogeny; Phthirus2004
6 Clayton, Dale H.Biology, ecology, and evolution of chewing liceChewing lice are small, dorsoventrally compressed insects and are parasites of virtually all birds (Fig. 1) and some mammals (Fig. 2). Many chewing lice are host specific, being found on only a single species of host. All chewing lice are permanent ectoparasites and complete their entire life c...Chewing lice2003
7 Lawton, Kristy J.Motor neurons tune premotor activity in a vertebrate central pattern generatorCentral patterns generators (CPGs) are neural circuits that drive rhythmic motor output without sensory feedback. Vertebrate CPGs are generally believed to operate in a top-down manner in which premotor interneurons activate motor neurons that in turn drive muscles. In contrast, the frog (Xenopus la...CPG; feed back; synchrony; vocal; vocalization; Xenopus2017
8 Sekercioglu, CaganChewing lice (Phthiraptera) species found on Turkish shorebirds (Charadriiformes)Approximately 4.500 species of lice have been so far described, with about 4.000 species seen on birds and with 3.000 species in the suborder Ischnocera 1. There are 465 bird species so far recorded in Turkey and the actual total is likely to exceed 500 species. However, the chewing lice fauna of th...2010-01-01

10 Clayton, Dale H.Experimental test of the importance of preen oil in Rock Doves (Columba livia)Most species of birds have a uropygial gland, also known as a preen gland, which produces oil that birds spread through their plumage when preening. The plumage of waterfowl deprived of uropygial oil becomes brittle and is subject to breakage.Columba livia; Columbiformes; Preen oil; Ectoparasites; Columbicola columbae; Campanulotes compare; Plumage2003
11 Adler, Frederick R.Effect of 1918 PB1-F2 expression on influenza A virus infection kineticsRelatively little is known about the viral factors contributing to the lethality of the 1918 pandemic, although its unparalleled virulence was likely due in part to the newly discovered PB1-F2 protein. This protein, while unnecessary for replication, increases apoptosis in monocytes, alters viral po...2011

13 Clayton, Dale H.; Bush, Sarah ElizabethIs melanin a defense against feather-feeding lice?The adaptive basis of plumage color has received much attention, including the finding that color can reveal information about parasite loads to potential mates. A related possibility, that color may be a direct defense against parasites, has received less attention.Columba livia; Columbiformes; Ectoparasites; Columbicola columbae; Campanulotes compare; Plumage color; Eumelanin; Preening2006
14 Clayton, Dale H.Ecoimmunity in Darwin's finches: invasive parasites trigger acquired immunity in the medium ground finch (Geospiza fortis)Invasive parasites pose a serious threat to native animal populations, because hosts with no history of exposure may lack effective immune defenses. Invasive parasites are a particular threat to small, island populations [1,2]. For example, introduced malaria (Plasmodium relictum) has exacerbated t...Darwins finches; Ecoimmunity; Acquired immunity; Medium ground finch; Geospiza fortis; Invasive parasites; Novel parasites; Poxvirus avium; Nest flies; Philornis downsi2010-01-06
