Fly me to the canopy: Diptera communities in oak forest crowns as bioindicators of stand decline

open access: yesInsect Conservation and Diversity, EarlyView.
Diptera diversity: Oak decline increases the overall Diptera diversity, particularly in saproxylic and floricolous guilds, likely due to more open canopies and greater deadwood and floral resource availability. Family responses: Dolichopodidae, Empididae, Hybotidae and Anthomyiidae thrive in declining stands, whereas Mycetophilidae and other fungus ...

Dieback of Fraxinus excelsior [PDF]

open access: yes, 2013
Ash dieback caused by Hymenoscyphus pseudoalbidus (anamorph Chalara fraxinea) is a disease that has emerged during the past twenty years. It was first observed in Poland and has expanded over most of the distribution area of European ash (Fraxinus excelsior) in Europe. This thesis comprises four scientific papers.

Against the odds: Nesting specialization and foraging ecology provide insights into climate change responses in a mountain bee

open access: yesInsect Conservation and Diversity, EarlyView.
A unique high‐elevation Exoneura bee defies typical elevation‐driven declines in bee activity, nesting exclusively in dead branches of snow gums near the alpine tree line. Nesting and foraging are tightly linked to snow gum presence, with most activity occurring within 30 m of these trees. Biophysical modelling indicates the bee's thermally constrained

History of Phytophthora cinnamomi management in Western Australia

open access: yes, 2005
Phytophthora cinnamomi has recently been recognized as a key threatening process to biodiversity in Australia. The impact of this introduced microscopic water mould on destruction of forests and heath land communities has been observed since 1921 in ...

Establishing Baseline Information for the Risk of Flatheaded Borer Attack in Specialty Tree Crops Using Trapping and On‐Farm Surveys

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Flatheaded borers (Coleoptera: Buprestidae) are largely xylophagous insects. Larvae of flatheaded borers tunnel into the trunks of trees, with boring and feeding damage eventually appearing on the surface as discolored bark, sunken areas, bark splits or bark sloughing.

Combined phylogenetic and geographic data can predict plant–pest interactions with high accuracy

open access: yesNew Phytologist, EarlyView.
Schematic overview of the study pipeline. Summary Non‐native plant pests can pose major threats to biodiversity, with destructive ecological and economic consequences. The ability to predict future threats would allow limited resources to be concentrated on managing the most serious risks. We built a Bayesian model to predict hosts at risk from Agrilus,

Assessment of Acacia Koa Forest Health across Environmental Gradients in Hawai‘i Using Fine Resolution Remote Sensing and GIS

open access: yesSensors, 2011
Koa (Acacia koa) forests are found across broad environmental gradients in the Hawai‘ian Islands. Previous studies have identified koa forest health problems and dieback at the plot level, but landscape level patterns remain unstudied.

MAPLE DIEBACK IN ONTARIO

open access: yesThe Forestry Chronicle, 1965
Maple dieback, a disease condition of unknown etiology affecting sugar maple and other hardwoods in woodlots, was studied over a 6-year period to determine its severity and extent. Data from permanent sample plots showed a consistent recovery trend during this period among moderately affected maple and other hardwood species.

Ectopic Expression of ScALDH21 From a Desert Moss Enhances Cotton Resistance to Verticillium Wilt via the Modulation of Jasmonates and Phenylpropanoid Pathways

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Biotic stresses, particularly Verticillium wilt (VW), lead to a global decline in cotton yields. Here, we demonstrate that ectopic expression of ScALDH21, a gene from the desiccation‐tolerant moss Syntrichia caninervis Mitt. and absent in angiosperms, enhances cotton's resistance to VW.
