Abstract "The available literature data on the species diversity and geographical distribution of Collembola in Canada and Alaska is summarized. In total, the checklist covers 541 named species of Collembola. This includes 475 species in 135 genera from 24 families recorded from Canada, as well as 241 species in 75 genera from 19 families reported from Alaska. For each species the current name, basionym with a full reference, records for different provinces and territories with their authorships, and general distributional ranges are given. Taxonomic remarks have been added when necessary. The checklist is based on 536 references (including 262 with Canadian records) published up to May 2018 and on a number of publicly available online resources. Keywords: Collembola, springtails, species list, taxonomic remarks, distribution, Canada, Alaska, Collembola"--Page 6.

This book discusses several recent theoretic advancements in interdisciplinary and transdisciplinary integration in the field of evolution. While exploring novel views, the text maintains a close link with one of the most broadly held views on evolution, namely that of “Darwinian evolution.” This work puts forth a new point of view which allows researchers to define in detail the concept of evolution. To create this conceptual definition, the text applies a stringent object-based focus. With this focus, the editor has been able to develop an object-based pattern of evolution at the smallest scale. Subsequently, this smallest scale pattern is used as an innovative basis for generalization...

In the form of a symposium on earthwo...
