Notes on North American Myriapoda of the Family Geophilid ^ , with Descriptions of Three Genera
When, in 1814, Leach erected the family Geophilidce, he proposed but the one genus, Oeophilus. From that time until 18G6 thirteen genera were described, four by Newport, one by Gray, and eight by C. Koch. The characters employed by these writers were external and extremely variable, and the genera established upon them did not, 'for the most part, represent natural groups. The character of the ...
متن کاملNotes on Lower-Bounds for Testing
Recall that we showed that there is an algorithm for testing triangle-freeness of dense graphs that had a dependence on 1/ that was quite high. While we cannot exactly match that dependence with a lower bound, we’ll show that a super-polynomial dependence is necessary. Here we’ll give the proof only for the one-sided error case, and note that it can be extended to two-sided error algorithms. Na...
متن کاملThe distribution of the vascular plants on the North Frisian Island, Amrum
Amrum is a small barrier island on the north-west coast of Germany. The distribution of vascular plants was examined by surveying their 1km(2) grid square occupancy across the whole island. These data were used in a study on the recent vegetation change in the island. These data include 3786 observations of 450 taxa collected in two surveys in 2007 and 2008.
متن کاملNew Synonymy , New Species , and Taxonomic Notes of North American Pityophthorus ( Coleoptera : Scolytidae ) , Part Iii
— New synonymies and new data affecting North American Pityophthortis are proposed as follows: chalcoensis Hopkins { = herrerai Hopkins) and nigricans Blandford ( = chiapensis Bright). Neotypes are designated for the following species described by Eichhoff: concentralis, cribripennis, infans, puchellus, and tuberculatus.
