THE PHANTOM PLATEAU1

Microsatellite primers in Agave utahensis (Asparagaceae), a keystone species in the Mojave Desert and Colorado Plateau1

UNLABELLED PREMISE OF THE STUDY Utah agave (Agave utahensis) and its putative subspecies, A. utahensis subsp. kaibabensis and A. utahensis subsp. utahensis, are keystone species of the Mojave Desert and Colorado Plateau in the southwestern United States. Here we developed microsatellite markers to study population structure and genetic diversity of the two subspecies of A. utahensis. • MET...

Development of SSR markers from transcriptomes for Orinus (Poaceae), an endemic of the Qinghai–Tibetan Plateau1

PREMISE OF THE STUDY Transcriptomes were used to develop microsatellite markers for the plant genus Orinus (Poaceae), which comprises three species of grasses (O. thoroldii, O. kokonoricus, and O. intermedius) that are widely distributed in the Qinghai-Tibetan Plateau. METHODS AND RESULTS Primer pairs were developed for 16 high-quality simple sequence repeats (SSRs) using transcriptomes. SSRs...

Crossing the phantom divide

We consider fluid perturbations close to the ‘‘phantom divide’’ characterized by p and discuss the conditions under which divergencies in the perturbations can be avoided. We find that the behavior of the perturbations depends crucially on the prescription for the pressure perturbation p. The pressure perturbation is usually defined using the dark energy rest-frame, but we show that this frame ...

The Phantom Herd

The phantom of transparency

I will discuss the status of the implicit and the explicit in science, mostly in logic1. I will especially denunciate, expose a deep and pregnant unsaid of scientific activity : the subliminal idea that, beyond immediate perception, could exist a world, a layer of reading, completely intelligible, i.e., explicit and immediate. What I will call the fantasy (or phantom, as a matter of joke) of tr...
