The Transcription Factor VdHapX Controls Iron Homeostasis and Is Crucial for Virulence in the Vascular Pathogen Verticillium dahliae

open access: yesmSphere, 2018
Iron homeostasis is essential for full virulence and viability in many pathogenic fungi. Here, we showed that the bZip transcription factor VdHapX functions as a key regulator of iron homeostasis for adaptation to iron-depleted and iron-excess conditions

A roadmap to key traits of invasive Drosophilidae

open access: yesBiological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

Incorporating climate change into pest risk models for forest pathogens : a role for cold stress in an era of global warming?

open access: yes, 2013
Climate change may alter the distribution and activity of native and alien pathogens that infect trees and, in severe cases, cause tree death. In this study, potential future changes in climate suitability are investigated for three forest pathogens that

Classifying avian drinking behaviour: ecological insights and implications in a changing world

open access: yesBiological Reviews, EarlyView.
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

Recurrent and synchronous insect pest outbreaks in forests [PDF]

open access: yesTheoretical Population Biology, 2012
A minimal model for the interactions of trees, insects, and their enemies suggests a simple formula for splitting all forests where insect outbreaks can occur into two categories: where outbreaks are periodic and endogenously generated and where outbreaks are triggered by exogenous factors and are, in general, recurrent but aperiodic. The formula is in

Development of monitoring methods for Hemlock Woolly Adelgid induced tree mortality within a Southern Appalachian landscape with inhibited access [PDF]

open access: yes, 2016
Hemlock woolly adelgid (Adelges tsugae Annand, HWA) is an introduced invasive forest pest in eastern North America. Herbivory by this insect results in mortality to eastern hemlock (Tsuga canadensis L.

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

open access: yesBiological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.
