Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

open access: yesInsect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

open access: yesIntegrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

One-pot multi-reaction processes: synthesis of natural products and drug-like scaffolds [PDF]

open access: yes, 2014
One-pot multi-reaction processes involving Overman rearrangements, metathesis cyclizations, and Diels–Alder reactions have been developed for the rapid and efficient synthesis of amino-substituted carbocyclic and heterocyclic compounds.

Parental Age, Inbreeding and Incubation Method Influence Extremely Low Hatching Success in the Ex‐Situ Population of the Extinct in the Wild Sihek

open access: yesAnimal Conservation, EarlyView.
Reproductive success rates are a key parameter determining the recovery potential of ex‐situ managed threatened species, with high rates often being required to produce offspring for wild releases while ensuring ex situ population viability. Here, we quantify reproductive success rates in the Extinct in the Wild sihek (Guam kingfisher) and find ...

Neuroimaging of the joint Simon effect with believed biological and non-biological co-actors

open access: yesFrontiers in Human Neuroscience, 2015
Performing a task alone or together with another agent can produce different outcomes. The current study used event-related functional magnetic resonance imaging (fMRI) to investigate the neural underpinnings when participants performed a Go/Nogo task ...

Using Periodic Matrix Models to Simulate the Effectiveness of Alternative Reintroduction Strategies for Lizards on a Seasonal Tropical Island

open access: yesAnimal Conservation, EarlyView.
Guam's lizard fauna has been devastated by the invasive brown treesnake, but recent advances in brown treesnake control have opened the possibility of reintroducing native lizards. We simulated different strategies for reintroducing lizards to Guam, comparing the timing and age‐structure of releases.
