    Summary: This book provides a foundation for modern applied ecology. Much of current ecology research and conservation addresses problems across landscapes and regions, focusing on spatial patterns and processes. This book is aimed at teaching fundamental concepts and focuses on learning-by-doing through the use of examples with the software R. It is intended to provide an entry-level, easily accessible foundation for students and practitioners interested in spatial ecology and conservation.

    The dnaB266(Am) mutation in Escherichia coli K-12 is an amber mutation such that strains carrying this mutation are not viable in a sup+ strain. With five different R plasmids, it has been possible to construct viable R+ derivatives of this amber mutant and show that the plasmids themselves do not carry amber suppressors. This is interpreted as evidence for the presence of dnaB analog genes associated with these plasmids. Plasmid-positive strains carrying these genes often showed some degree of cryosensitivity of DNA synthesis and colony-forming ability. These observations indicate that the presence of dnaB analog genes in association with R plasmids must be relevant to the plasmid state or to some aspect of conjugative ability.
