Subtype-selective GABAergic drugs facilitate extinction of mouse operant behaviour

open access: yesNeuropharmacology, 2004
Several recent studies have shown that reducing gamma-aminobutyric acid (GABA)-mediated neurotransmission retards extinction of aversive conditioning. However, relatively little is known about the effect of GABA on extinction of appetitively motivated ...

Disease-selective predation may lead to prey extinction

open access: yesMathematical Methods in the Applied Sciences, 2005
In real world bio-communities, predational choice plays a key role to the persistence of the prey population. Predator's 'sense' of choice for predation towards the infected and noninfected prey is an important factor for those bio-communities. There are

High-extinction-ratio TE/TM selective Bragg grating filters on silicon-on-insulator [PDF]

open access: yesOptics Letters, 2017
We report on the design and fabrication of TE and TM polarization selective Bragg grating filters in the form of sinusoidal perturbations on the waveguide sidewall and etched holes on the top of the waveguide, respectively.

Selecting for extinction: nonrandom disease‐associated extinction homogenizes amphibian biotas

Ecology Letters, 2009
AbstractStudying the patterns in which local extinctions occur is critical to understanding how extinctions affect biodiversity at local, regional and global spatial scales. To understand the importance of patterns of extinction at a regional spatial scale, we use data from extirpations associated with a widespread pathogenic agent of amphibian decline,

Biological Selectivity of Extinction: A Link between Background and Mass Extinction

PALAIOS, 1986
The phenomenon of non-random or selective survival across major extinction boundaries in the geologic past is poorly understood but increasingly recognized as a critical area for future research. A current hypothesis, developedfrom a comparison of extinction patterns among Late Cretaceous molluscs, is that biological adaptations of organisms effectual ...
