Evolutionary history of threespine sticklebacks (Gasterosteus spp.) in British Columbia: insights from a physiological clock

Geologic and allozyme evidence suggests that threespine sticklebacks (Gasterosteus aculeatus complex) in low-lying southwestern British Columbia lakes were founded during two incursions of marine sticklebacks after the retreat of the Pleistocene glaciers (the double-invasion hypothesis). We used the salinity tolerance of embryos, measured as hatchability in salt water, to establish the relative...

Rapid detection of carbapenemase-producing Pseudomonas spp.

A novel biochemical technique, the Carba NP test, has been evaluated to detect carbapenemase production in Pseudomonas spp. This test was specific (100%), sensitive (94.4%), and rapid (<2 h). This cost-effective test, which could be implemented in any microbiology laboratory, offers a reliable technique for identification of carbapenemase-producing Pseudomonas spp.

History of Evolutionary Theory

The term "evolution" is linked to the idea of development in the sciences of life, and only subsequently did it acquire the present meaning of diversification and origin of new species. The dominant image of the scala naturae, strictly related to the creationist, static and essentialistic positions, was substituted by the image of the tree that characterizes the transformist theories, and that ...

Evolutionary history of subspecies of Eurasian nuthatches (Sitta europaea persica) from Zagros Mountains, Iran

Abstract. Eurasian Nuthatch (Sitta europaea), with 18 subspecies, has a wide distribution in deciduous forests of Eurasia. The subspecies S.e.persica is a resident bird in the Zagros Mountains, from north-west to south-west of Iran. The aim of this study was to evaluate the taxonomic and phylogenetic relationships of this subspecies to European, Asian, as well as Caucasian clades. For this purp...
