Zamba by you: possible stridulation during courtship in a spider with bridal veil (Ctenidae)

Guasuctenus longipes es una araña asociada a ambientes de quebrada. El objetivo de este estudio fue explorar la existencia de estructuras estridulatorias y emisión de sonido. Se describe el raspador y la lira en los palpos de los machos. Al tratarse de una especie nocturna, sugerimos que el canal acústico es preponderante para el encuentro de los sexos.Guasuctenus longipes is a spider associated with stream environments. The objective of this study was to explore the presence of stridulatory organs and sound emission. Scraper and ridges on the pedipalps of males were described. As it is a nocturnal species, we suggest that the acoustic channel is preponderant for the meeting of the sexes

Genetic tool development in marine protists: emerging model organisms for experimental cell biology

Abstract: Diverse microbial ecosystems underpin life in the sea. Among these microbes are many unicellular eukaryotes that span the diversity of the eukaryotic tree of life. However, genetic tractability has been limited to a few species, which do not represent eukaryotic diversity or environmentally relevant taxa. Here, we report on the development of genetic tools in a range of protists primarily from marine environments. We present evidence for foreign DNA delivery and expression in 13 species never before transformed and for advancement of tools for eight other species, as well as potential reasons for why transformation of yet another 17 species tested was not achieved. Our resource in genetic manipulation will provide insights into the ancestral eukaryotic lifeforms, general eukaryote cell biology, protein diversification and the evolution of cellular pathways
