NZJFS Special Issue - Novel and classical strategies to manage forest health in plantations
Presenters at the conference are invited to contribute to a Special Issue of the New Zealand Journal of Forestry Science (NZJFS) https://nzjforestryscience.nz/index.php/nzjfs.
NZJFS is an international journal covering the breadth of forestry science. The journal's scope covers all forestry species, particularly those used in plantations.
NZJFS has an Impact Factor of 0.926 and CiteScore of 2.6. NZJFS has the advantage of being Open Access, with no Article Submission or Processing Charges.
Topics of the special issue will mirror those of the conference:
- Biological control of plantations pests and new technologies
- Biosecurity measures for invasive pests and pathogens
- Climate change affecting forest health
- New technologies for pest and diseases surveillance
- Pest and disease management strategies
- Status of pests and diseases in plantations worldwide
Original Articles must report on a completed piece of substantial research that is relevant to an international audience. In all cases, a hypothesis must be presented, and results must be sound without errors of fact, logic, interpretation, or calculation. Key details must be provided for all methods used. The correct statistical tests must be applied, where appropriate. Discussion sections must be logical and comprehensive, yet concise. Any conclusions must be justified and supported by the data presented.
Short Notes and Subject Reviews are also invited.
Deadline for manuscript submissions: 31 January 2024

Hybridization and the resulting introgression can drive the success of invasive species via the rapid acquisition of adaptive traits. The Dutch elm disease pandemics in the past 100 years were caused by three fungal lineages with permeable reproductive barriers: Ophiostoma ulmi, Ophiostoma novo-ulmi subspecies novo-ulmi and Ophiostoma novo-ulmi subspecies americana. Using whole-genome sequences and growth phenotyping of a worldwide collection of isolates, we show that introgression has been the main driver of genomic diversity and that it impacted fitness-related traits. Introgressions contain genes involved in host–pathogen interactions and reproduction. Introgressed isolates have enhanced growth rate at high temperature and produce different necrosis sizes on an in vivo model for pathogenicity. In addition, lineages diverge in many pathogenicity-associated genes and exhibit differential mycelial growth in the presence of a proxy of a host defence compound, implying an important role of host trees in the molecular and functional differentiation of these pathogens.
