Divergent shifts in hydraulic versus carbon acquisition functional traits after wildfire in four Rocky Mountain tree species

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change has increased the frequency and severity of drought and large wildfire events across western North America. Despite the increasing concurrence of drought and wildfire events and the importance of forests as a global carbon sink, the impacts of fire on ...

Infection of Barley by Brome Mosaic Virus Is Restricted Predominantly to Cells in and Associated with Veins through a Temperature-Dependent Mechanism

open access: yesMolecular Plant-Microbe Interactions, 1999
Results from previous cytological studies on barley (Hordeum vulgare) infected with brome mosaic virus (BMV) indicated that this virus can infect and accumulate to high levels in mesophyll and other cell types within the leaves.

The social life of money for children

open access: yesThe British Journal of Sociology, EarlyView.
Abstract Inspired by Nigel Dodd's The Social Life of Money, this article proposes an analysis of entangled economic lives, that is, how meaning, structures and politics jointly shape the flow of monies within households. The past decades have marked a shift from “childrearing expenditures” to “parenting investments” that align with new visions of both ...

Influence of Temperature on Cambial Activity and Cell Differentiation in Quercus Sessiliflora and Acer Pseudoplatanus of Different Ages

open access: yesDrvna Industrija, 2013
We evaluated the response of active cambium of sessile oak (Quercus sessiliflora) and sycamore maple (Acer pseudoplatanus) to experimentally increased (20–22 °C) and decreased (9–11 °C) temperatures.

Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

open access: yesInsect Science, EarlyView.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be

Determining the Composition of Lignins in Different Tissues of Silver Birch

open access: yesPlants, 2015
Quantitative and qualitative lignin analyses were carried out on material from the trunks of silver birch (Betula pendula Roth) trees. Two types of material were analyzed.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

open access: yesInsect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Increased xylem ingestion and decreased phloem ingestion in the aphid Acyrthosiphon pisum (Hemiptera: Aphididae) parasitised by Aphidius ervi (Hymenoptera: Braconidae)

open access: yesEuropean Journal of Entomology, 2006
The effects of parasitisation by Aphidius ervi on the feeding behaviour of the aphid Acyrthosiphon pisum were studied. There was progressive increase in the time devoted to xylem ingestion (G waveform) and concomitant decrease in time devoted to phloem ...

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

open access: yesInsect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.
