Tracking the signal in year-class strength of Northeast Arctic cod through multiple survey estimates of egg, larval and juvenile abundance

Journal of Sea Research, 2003
Abstract Egg and larval abundances for Northeast Arctic cod estimated annually from 1959–1993 were combined with estimates of spawning stock biomass (SSB) and stage abundance estimates for the larvae, pelagic juveniles and demersal juveniles to determine when a correlation with recruitment could first be detected and to track how the correlation ...

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

Pest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Coupling of potential habitat models with particle tracking experiments to examine larval fish dispersal and connectivity in deep water regions

PLOS ONE
Computing Lagrangian trajectories with ocean circulation models is a powerful way to infer larval dispersal pathways and connectivity. Defining release areas and timing of particles to represent larval habitat realistically is critical to obtaining representative dispersal pathways.

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

Pest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Persistence of an Endangered Amphibian in a Fully Anthropogenic Forested Pondscape

Ecology and Evolution
Anthropogenic habitats can play a pivotal role in species persistence within human‐modified landscapes. We examined aquatic habitat use by Bombina variegata, an endangered amphibian that relies entirely on a dense network of 157 human‐made temporary ...

Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus)

Pest Management Science, EarlyView.
We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.

Synergistic transition from type‐I‐like to type‐II‐like symptomology in a pyrethroid mixture and its impact on knockdown–mortality relationships in Musca domestica L

Pest Management Science, EarlyView.
In the present study, relationship between knockdown and mortality of insecticides was examined against the adult female housefly, Musca domestica. Type‐I pyrethroid insecticides showed a weak linkage, as early knocked down flies did not always result in mortality, while type‐II pyrethroids and organophosphates exhibited strong correlation between the ...

PCR‐based species identification tools for wireworms (Coleoptera: Elateridae) of economic importance in Canada

Pest Management Science, EarlyView.
Species‐specific PCR primers and PCR‐based assays were designed for the identification of 15 economically important and difficult to distinguish wireworm pests in Canada. PCR specificity testing and performance assessments confirm the accuracy of the assays.
