Biological Flora of Britain and Ireland: Cytisus scoparius*

open access: yesJournal of Ecology, EarlyView.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Biological invasion by the cycad‐specific scale pest Aulacaspis yasumatsui (Diaspididae) into Cycas revoluta (Cycadaceae) populations on Amami‐Oshima and Okinawa‐jima, Japan

open access: yesPlant Species Biology, EarlyView.
This article details the invasion of cycad aulacaspis scale into the islands of Okinawa‐Jima and Amami‐Oshima. Several recommendations are proposed in this article by members of the IUCN cycad specialist group and experts in the biological control of this scale insect.

Differences in within‐plant oviposition preferences and immature survival between Orius predators and the importance of spatial availability of prey

open access: yesInsect Science, EarlyView.
Orius predators oviposit endophytically, and plant characteristics play an important role in their oviposition choices. In this study, we show that oviposition preferences differ between species, and that these differences may correlate with juvenile performance.

Reducing parasitic capacitance of strained Si nano p-MOSFET by control of virtual substrate doping [PDF]

open access: yesarXiv, 2015
Biaxially strained Si channel p-MOSFETs on virtual SiGe substrates suffer from a parasitic parallel channel in virtual substrate. This channel participates in current passing through the devices and increases parasitic capacitors which degrades the high frequency response.

ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.

Population dynamics of stubby root nematodes (Trichodorus and Paratrichodorus spp.) associated with ‘Docking disorder’ of sugar beet (Beta vulgaris L.), in field rotations with cover crops in East England

open access: yesAnnals of Applied Biology, EarlyView.
This study evaluated the population dynamics of stubby root nematodes (SRN) in field rotations with cover crops and the subsequent effect of this rotation on sugar beet quality and quantity attributes. It was clear that the SRN densities under field conditions are influenced by multiple factors, such as the type of cover crops grown, soil disturbance ...
