Siraton devillei Hustache, 1934, described from a single specimen collected on the island of Elba in Italy, is determined to be conspecific with the Australian cycad weevil Melanotranes internatus (Pascoe, 1870). Consequently, Melanotranes Zimmerman, 1994 is a new junior synonym of Siraton Hustache, 1934 and Siraton devillei Hustache, 1934 a new junior subjective synonym of Tranes internatus Pa...

After weaning, groups of rats were fed a semi-purified diet containing fiddlehead greens (the unfuried frond of the ostrich fern Matteuccia struthiopteris), mature bracken fern (Pteridium aquilinum), or cycad meal (Cycas circinalis), or this diet plus aflatoxin B1. The groups fed 1-10% fiddlehead greens for 70-73 weeks developed no tumors, whereas those fed mature bracken fern for 67 weeks deve...

The reproductive organs of some plants self-heat, release scent, and attract pollinators. The relations among these processes are not well understood, especially in the more ancient, nonflowering gymnosperm lineages. We describe the influence of plant volatiles in an obligate pollination mutualism between an Australian Macrozamia cycad (a gymnosperm with male and female individuals) and its spe...

The armored scale Aulacaspis yasumatsui invaded the northern range of the cycad Cycas micronesica in 2003, and epidemic tree mortality ensued due to a lack of natural enemies of the insect. We quantified cycad demographic responses to the invasion, but the ecological responses to the selective removal of this foundation species have not been addressed. We use this case to highlight information ...

Pantoea latae strain AS1 was isolated from the rhizophere of a cycad, Zamia floridana, in central Florida, USA. Here, we report the de novo whole-genome sequence of this strain, which consists of a total of 83 contigs spanning 4,960,415 bp, with a G+C content of 59.6%, and comprising 4,527 predicted coding sequences.
