A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

open access: yesEcological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

Evidence for a defensive ceiling in the effectiveness of plant silicon defences against an insect herbivore

open access: yesEcological Entomology, EarlyView.
Silicon‐mediated resistance in wheat reaches a defensive plateau; accumulating silicon beyond 2mM provides no additional benefit for suppressing insect herbivore relative growth rates. Silicon supplementation significantly increases wheat biomass and effectively ameliorates plant mass losses caused by Helicoverpa armigera herbivory. Lower mandible wear

Examining the Impact of Derelict Pots on Blue Crab (Callinectes sapidus) Catch and Harvest Within a Recreational Fishery

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

The xylem water transport network: just safe enough to keep flowing

open access: yes
In plants, water lost through leaf transpiration must be replenished by root water uptake. Regardless of plant size, the xylem vascular system ensures this balance, supporting leaf gas exchange and maintaining a positive carbon balance. Leaf water supply

Development of an Artificial Liquid Diet for Allelochemical Delivery in Lycorma delicatula

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Spotted lanternfly, Lycorma delicatula White (Hemiptera: Fulgoridae), is an invasive phloem‐feeding planthopper native to Asia, which poses a growing threat to US agriculture due to its broad host range and rapid spread since its 2014 detection. To better understand how L.

Volatile organic compounds orchestrating microbiome‐mediated crop resilience: Prospects and challenges for sustainable agriculture

open access: yesJournal of Integrative Plant Biology, EarlyView.
Herbivory triggers the production of green leaf volatiles, and dense planting results in induces increased concentration of linalool emission in maize canopies. These volatiles activate plant‐soil feedback that enriches beneficial rhizosphere bacteria, enhancing resistance, though sometimes at a growth cost, thereby offering new avenues for sustainable

CryoFluorSEM – A new approach for fluorescence and EM imaging of cryofractured plant samples

open access: yesJournal of Microscopy, EarlyView.
Abstract Cryo‐scanning electron microscopy (CryoSEM) permits the preparation and detailed imaging of bulky samples while keeping them in a hydrated state. For plant biology, cryofractures give information on cell ultrastructure and tissue organisation within a much larger context that is the whole organ or organism.

Salivary Viscosity as a Non‐Invasive Candidate Biomarker Associated With Aspiration Risk in Oculopharyngeal Muscular Dystrophy

open access: yesJournal of Oral Rehabilitation, EarlyView.
Patients with oculopharyngeal muscular dystrophy exhibit disease‐specific salivary hyperviscosity that tracks with dysphagia severity and airway invasion. Non‐invasive chairside screening of salivary viscosity may enable clinicians to stratify aspiration risk during routine care to prevent severe pulmonary complications.
