Diversity and host associations of Myrsidea chewing lice (Phthiraptera: Menoponidae) in the tropical rainforest of Malaysian Borneo
Madrid, Ramón Soto; Sychra, Oldřich; Benedick, Suzan; Edwards, David P.; Efeykin, Boris D.; Fandrem, Marte; Haugaasen, Torbjørn; Teterina, Anastasia; Tomassi, Suzanne; Tolstenkov, Oleg (Journal article; Peer reviewed, 2020)The tropical rainforests of Sundaland are a global biodiversity hotspot increasingly threatened by human activities. While parasitic insects are an important component of the ecosystem, their diversity and parasite-host ... -
Five New Species of Guimaraesiella (Phthiraptera: Ischnocera) from Broadbills (Aves: Passeriformes: Calyptomenidae: Eurylaimidae)
Gustafsson, David; Malysheva, Olga D; Tolstenkov, Oleg; Bush, Sarah E (Journal article; Peer reviewed, 2019)Five new species of Guimaraesiella Eichler, 1949 are described and illustrated from hosts in the Eurylaimidae and Calyptomenidae. They are Guimaraesiella corydoni n. sp. from Corydon sumatranus laoensisMeyer de Schauensee, ... -
Gap junction-dependent coordination of intercellular calcium signalling in the developing appendicularian tunicate Oikopleura dioica
Mikhaleva, Yana; Tolstenkov, Oleg; Glover, Joel (Journal article; Peer reviewed, 2019)We characterized spontaneous Ca2+ signals in Oikopleura dioica embryos from pre-fertilization to gastrula stages following injection of GCaMP6 mRNA into unfertilized eggs. The unfertilized egg exhibited regular, transient ... -
A miniaturized nigrostriatal-like circuit regulating locomotor performance in a protochordate
Tolstenkov, Oleg; Mikhaleva, Yana; Glover, Joel Clinton (Journal article; Peer reviewed, 2023)To gain insight into the evolution of motor control systems at the origin of vertebrates, we have investigated higher-order motor circuitry in the protochordate Oikopleura dioica. We have identified a highly miniaturized ... -
Neuronal gene expression in two generations of the marine parasitic worm, Cryptocotyle lingua
Tolstenkov, Oleg; Chatzigeorgiou, Marios; Gorbushin, Alexander (Journal article; Peer reviewed, 2023)Trematodes, or flukes, undergo intricate anatomical and behavioral transformations during their life cycle, yet the functional changes in their nervous system remain poorly understood. We investigated the molecular basis ... -
Transcriptional adaptation in caenorhabditis elegans
Serobyan, Vahan; Kontarakis, Zacharias; El-Brolosy, Mohamed A.; Welker, Jordan M.; Tolstenkov, Oleg; Saadeldein, Amr M.; Retzer, Nicholas; Gottschalk, Alexander; Wehman, Ann M; Stainier, Didier YR (Journal article; Peer reviewed, 2020-01)Transcriptional adaptation is a recently described phenomenon by which a mutation in one gene leads to the transcriptional modulation of related genes, termed adapting genes. At the molecular level, it has been proposed ...
