Tibicinoides, with three small endemic California cicada species, has a confusing, intertwined systematic history Okanagana that we unravel here. An ingroup including all species of Tibicinoides and the majority (84.7%) were sampled for six gene regions, polarized Clidophleps, Okanagodes, Subpsaltria, Tibicina outgroups, subjected to Bayesian phylogenetic analysis. Although was monophyletic fro...

Sensory modalities typically are important for both sexes, although sex-specific functional adaptations may occur frequently. This is true for hearing as well. Consequently, distinct behavioural functions were identified for the different insect hearing systems. Here we describe a first case, where a trait of an evolutionary novelty and a highly specialized hearing organ is adaptive in only one...

Based on the recent ascertaining studies of type specimens, the new systematic placement for one subgenus and three species of oribatid mites of the family Galumnidae (Acari, Oribatida) are proposed, resulting in the following taxonomic proposals: Pergalumna (Bigalumna) Mahunka & Mahunka-Papp, 2009 stat. nov., P. (B.) rimosa (Mahunka & Mahunka-Papp, 2009) comb. nov., Allogalumna quadrimaculata ...

Six mexicanolide limonoids isolated from the dichloromethane extract of the fruits of Cipadessa fruticosa Blume (Meliaceae) were evaluated against Spodoptera frugiperda (J. E. Smith). Gedunin was used as a positive control. When incorporated into an artificial diet of neonates at 50.0 mg kg(-1), febrifugin A showed 73.3% mortality. All the compounds showed moderate insecticidal activity, except...

Predation, foraging and mating costs are critical factors shaping life histories. Among colonial seabirds, colony overflights may enhance foraging or mating success, or diminish the risk of predation and kleptoparasitism. The latter possibility is difficult to test because low predation or kleptoparasitism rates could be due either to low danger or to effective countertactics by prey. Tufted pu...

The difficulty involved in distinguishing between edible and poisonous mushrooms stems from their similar appearances. In this study, we attempted to classify five common species of found Thailand, Inocybe rimosa, Amanita phalloides, citrina, Russula delica, Phaeogyroporus portentosus, using the convolutional neural network (CNN) region (R-CNN). This study was motivated by yearly death toll eat...

The amount of cinchona alkaloids and other antimalarials falls far short of India's requirements. The recent introduction of synthetic antimalarials has been a welcome relief. Besides in day-to-day clinical practice it has been observed that patients would like to be treated with indigenous herbs or their decoctions in preference to quinine and its derivatives or the synthetic antimalarials whi...

Phanerochaete is a genus of resupinate homobasidiomycetes that are saprophytic on woody debris and logs. Morphological studies in the past indicated that Phanerochaete is a heterogeneous assemblage of species. In this study the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA was used to test the monophyly of the genus Phanerocthaete and to infer phylogenetic relationships ...
