Mechanisms of Odor Coding in Coniferous Bark Beetles: From Neuron to Behavior and Application

Psyche: A Journal of Entomology, 2012
Coniferous bark beetles (Coleoptera: Curculionidae: Scolytinae) locate their hosts by means of olfactory signals, such as pheromone, host, and nonhost compounds. Behavioral responses to these volatiles are well documented.

Divergent defense strategies and niche partitioning in Cretaceous micro‐beetles

Journal of Systematics and Evolution, EarlyView.
We report a new clambid beetle from mid‐Cretaceous Kachin amber, Scutacalyptus kolibaci gen. et sp. nov., characterized by a flattened body and explanate margins. Alongside spiny and conglobating clambid forms, this diversity reflects niche partitioning and varied antipredator strategies in the Cretaceous forest floor.

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, EarlyView.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

A Plant‐Based Platform for the Production of Bark Beetle Pheromones

Plant Biotechnology Journal, EarlyView.
ABSTRACT Bark beetle species of the genera Ips and Dendroctonus represent a threat to forests in both North America and Europe. Under normal circumstances, these beetles recycle dying trees into nutrients, but under certain conditions, growing populations can overcome healthy tree defenses and cause severe economic loss in forestry.

Harnessing Bulk‐Segregant Mapping to Identify Trait‐Associated Genes in the Allopolyploid Model Plant Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
ABSTRACT Forward genetics has been instrumental in identifying genes underlying desirable traits, yet its application to polyploid plants, many of which are key agricultural crops, remains challenging due to their genomic complexity. Therefore, we developed BenthMap, a bulk segregant analysis platform for high‐throughput trait mapping and gene ...

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

Plant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...

A conceptual model for the diapause intensity curve and termination in overwintering Japanese pine sawyer larvae, Monochamus alternatus (Coleoptera: Cerambycidae)

Physiological Entomology, EarlyView.
Larval diapause intensity of Monochamus alternatus follows a declining curve, beginning with an initial refractory phase and reaching termination after approximately 110 days of chilling at 9°C. Residual inhibitory state strongly influenced post‐chilling development; additional chilling shortened the diapause period more at 18°C than at warmer ...

Drought legacy in mature spruce alleviates physiological stress during recurrent drought

Plant Biology, EarlyView.
The slow recovery of leaf area in mature spruce following a long‐term drought alleviated physiological stress during recurrent drought. Abstract Forest ecosystems are facing severe and prolonged droughts with delayed recovery, known as “drought legacy”.

Recurrent hot droughts cause persistent legacy effects in a temperate Scots Pine forest

Plant Biology, EarlyView.
A series of hot drought events caused persistent legacy effects in a Scots Pine forest, with severe negative impacts on ecosystem carbon fluxes. Abstract Recent hot‐dry events have caused significant impacts and legacy effects in temperate ecosystems. Here, we investigate legacy effects of the 2018 hot drought on a Pinus sylvestris L.

Impact of emerging compound droughts on forests: A water supply and demand perspective

Plant Biology, EarlyView.
This review examines the physiological and ecological responses of trees to emerging compound droughts from a water demand and supply perspective, as well as the role of acclimation and consequences for ecosystem‐level functions. Abstract The intensification of climate change‐induced drought results in unprecedented tree and forest die‐offs worldwide ...
