Geographic distributions of pathogens are the outcome of dynamic processes involving host
availability, susceptibility and abundance, suitability of climate conditions, and historical …

Before an exotic pathogen can be released as a classical biological control agent the likely
positive and negative outcomes of that introduction must be predicted. Host range testing is …

This book is intended to be a brief compilation of the information available on the breeding
of temperate fruit crops. The goal is to provide overviews on the evolution of each crop, the …

Effective study in the native range to identify potential agents underpins all efforts in classical
biological control of weeds. Good agents that demonstrate both a high degree of host …

Aim The genetic makeup and evolutionary potential of alien species can be profoundly
influenced by their introduction history, but without detailed historical records, it can be …

• Premise of the study: Assessing propagule pressure and geographic origins of invasive
species provides insight into the invasion process. Rush skeletonweed (Chondrilla juncea; …

Impatiens glandulifera, or Himalayan balsam, is a prolific invader of riverine habitats.
Introduced from the Himalayas for ornamental purposes in 1839, this annual species has …

Exotic Rubus taxa in Australia have been revised following consultation with European and
North American experts in Rubus, allied with studies of variation in patterns of DNA …

In facultatively asexual invasive species, an understanding of the origins and diversity of
clones can reveal introduction and invasion pathways and inform management efforts. In …

Few crops are as genetically diverse as blackberry, with several Rubus species in its
background. This diversity is being used by plant breeders to fill a myriad of marketing …
