Damming a digital electricity reservoir: ion-regulated electronic digital energy driving in the [2]rotaxane.
The present study represents a taxonomic revision of the Pheidole sikorae species group from Madagascar. Forty-four members of this group are recognised and described, and an illustrated identification key to this group is also presented. One species is raised to species level P. litigiosa Forel, 1892 stat. nov.Pheidole veteratrix angustinoda Forel, 1892 syn. nov. is proposed as a junior synonym of Pheidole veteratrix Forel, 1891. Worker castes are also described and lectotypes designated for P. litigiosa Forel, 1892, P. sikorae Forel, 1891, and P. veteratrix Forel, 1891. The following 41 new species are described P. alinasp. nov., P. ambohimangasp. nov., P. analavelonasp. nov., P. andohahelasp. nov., P. anomalasp. nov., P. anosyennesp. nov., P. antranohofasp. nov., P. beankasp. nov., P. befotakasp. nov., P. dasossp. nov., P. flavominutasp. nov., P. gracilissp. nov., P. habokasp. nov., P. havoanasp. nov., P. hazosp. nov., P. itremosp. nov., P. joffrevillesp. nov., P. kelysp. nov., P. lavasoasp. nov., P. mahamavosp. nov., P. maintysp. nov., P. mamiratrasp. nov., P. mananteninasp. nov., P. masoandrosp. nov., P. mavohavoanasp. nov., P. midongysp. nov., P. mikrossp. nov., P. mivorysp. nov., P. Inhibitor Library cost nitidobrunasp. nov., P. parvulasp. nov., P. parvulogibbasp. nov., P. reniranosp. nov., P. savasp. nov., P. sofiasp. nov., P. sparsasp. nov., P. tamponysp. nov., P. trichotossp. nov., P. tsaravonianasp. nov., P. vadumsp. nov., P. volontanysp. nov., and P. vonysp. nov. At present, there are 109 valid species and subspecies of Pheidole known from Madagascar, but this number is expected to increase with upcoming taxonomic revisions of the species groups not revised in this study.Espírito Santo state is located on the eastern margin of Brazil, in a transitional tropical-subtropical area (18°S-21°S) dominated by oligotrophic waters. With the exception of humpback whales (Megaptera novaeangliae), the cetacean community of Espírito Santo has been understudied. In addition to the chronic impacts from fisheries, marine pollution, urban development, and coastal habitat degradation, in November 2015 the cetacean communities of Espírito Santo were challenged by the greatest environmental disaster in Brazil's history. The Mariana dam disaster caused 60 million cubic meters of mining waste to be washed into the Doce River, which ultimately flowed to the coastal waters of Espírito Santo, with a high concentration of heavy metals. This study reviews and updates information on cetacean strandings in the state of Espírito Santo (excluding humpback whales) prior to this disaster. From 1975 to September 2015, there were 461 recorded cetacean strandings, representing 20 species. An average 1.18 strandings per 100 km per month were recorded since a state-wide daily beach survey program was implemented in October 2010, contrasting with the 0.14 strandings per 100 km per month in previous years. Six species comprised the majority (94.7%) of stranding events Guiana dolphin (Sotalia guianensis), Franciscana (Pontoporia blainvillei), rough-toothed dolphin (Steno bredanensis), bottlenose dolphin (Tursiops truncatus), sperm whale (Physeter macrocephalus), and melon-headed whale (Peponocephala electra). Oceanic cetaceans stranded most frequently on the southern portion of Espírito Santo, where the continental platform is narrower, whereas the strandings of coastal cetaceans such as Guiana dolphins and Franciscanas were concentrated near estuaries, especially the Doce River. This is particularly concerning in face of the Mariana dam disaster, which drastically altered the estuarine and coastal environment associated with the Doce River.A dataset comprising 6806 records is presented of 17 (of total 24) rodent and insectivore species from the Crimean Peninsula collected during a 35-year period. All records are stored in the Public Mammal Database (Mammals of Russia; http//rusmam.ru/). The density of occurrence points allows visual evaluation of species distribution, even on large-scale maps. Each record contains the species name, locality description, and geographic coordinates, coordinate accuracy, date and author of the record, data source, and the method of species identification.Knowledge on the pygmy grasshoppers of Australia is, despite the numerous endemics being described from this unique continent, still scarce. Of interest is the Vingselina genus group, including genera Anaselina Storozhenko, 2019, Paraselina Storozhenko, 2019, Selivinga Storozhenko, 2019 and Vingselina Sjöstedt, 1921. The systematic position of this group, currently assigned to Batrachideinae (Bufonidini), is probably not correct. In this study new records are presented of Anaselina minor (Sjöstedt, 1921), Paraselina brunneri (Bolívar, 1887), P. trituberculata (Sjöstedt, 1932), and Selivinga tribulata Storozhenko, 2019, all except A. minor the first records of the species since their original descriptions. The first photographs of living specimens of A. minor, P. brunneri, P. trituberculata and S. tribulata are provided and their habitats described. All the records were compiled by citizen scientists who use online social media, such as iNaturalist. Lastly, P. multifora (Rehn, 1952) syn. nov. represents a junior synonym of P. brunneri.One of the largest species in its genus, Odontomachus davidsoni Hoenle, Lattke & Donoso, sp. nov. is described from workers and queens collected at lowland forests in the Chocó-Darién bioregion in coastal Ecuador. The workers are characterized by their uniform red coloration, their large size (16-18 mm body length), and their frontal head striation that reaches the occipital margin. DNA barcodes (COI) and high resolution 2D images of the type material are provided, as well as an updated key for the Neotropical species of Odontomachus. In addition, a three-dimensional digital model of the worker holotype and a paratype queen scanned with DISC3D based on photogrammetry is presented, for the first time in a species description. Findings of large and conspicuous new species are uncommon around the world and suggest that these Ecuadorian rainforests may conceal many more natural treasures that deserve conservation.
