Chromosomal DNA is exposed to continuous damage and repair. Cells contain a number of
proteins and specific DNA repair systems that help maintain its correct structure. The SOS …

The SOS system and SOS mutagenesis are frequently studied, or exploited to obtain an
increase in mutagenicity of bacteria. Here a short survey is made of the phenomenon of SOS …

A full-factorial study of the effects of rates of temperature change and start temperatures was
undertaken for both upper and lower critical thermal limits (CTLs) using the tsetse fly …

Synergies between global change and biological invasion have been identified as a major
potential threat to global biodiversity and human welfare. The global change-type drought …

Collembola is one of the major functional groups in soil as well as a model taxon in
numerous disciplines. Therefore the accurate identification of specimens is critical, but could …

Despite the importance of understanding the mechanisms underlying range limits and
abundance structure, few studies have sought to do so. Here we use a terrestrial slug …

The fundamental equation of the metabolic theory of ecology (MTE) indicates that most of
the variation in metabolic rate are a consequence of variation in organismal size and …

This is a short survey of the adaptive mutation processes that arise in non-or slowly-dividing
bacterial cells and includes:(i) bacterial models in which adaptive mutations are studied;(ii) …

Abstract N 4-Hydroxycytidine, 5-methyl-N 4-hydroxydeoxycytidine and 2-amino-N 6-
hydroxyadenine were tested for their mutagenic activity in S. typhimurium and E. coli cells …

The SOS system in Escherichia coli is induced in response to DNA damage and the arrest of
DNA synthesis. Here we show that in AB1157 bacteria starved for arginine, conditions for …
