Are hybrid species more fit than ancestral parent species in the current hybrid species habitats?
Hybrid speciation is thought to be facilitated by escape of early generation hybrids into new habitats, subsequent environmental selection and adaptation. Here, we ask whether two homoploid hybrid plant species (Helianthus anomalus, H. deserticola) diverged sufficiently from their ancestral parent species (H. annuus, H. petiolaris) during hybrid speciation so that they are more fit than the par...
متن کاملGenetic Incompatibility Dampens Hybrid Fertility More Than Hybrid Viability: Yeast as a Case Study
Genetic incompatibility is believed to be the major cause of postzygotic reproductive isolation. Despite huge efforts seeking for speciation-related incompatibilities in the past several decades, a general understanding of how genetic incompatibility evolves in affecting hybrid fitness is not available, primarily due to the fact that the number of known incompatibilities is small. Instead of fu...

More Hype Than HOPE To the Editor: In the recently published Heart Outcomes Prevention Evaluation (HOPE study),1 treatment with the ACE inhibitor ramipril was reported to reduce cardiovascular morbidity and mortality independent of blood pressure (BP) reduction. High-risk “normotensive” (BP 140/80 mm Hg) patients (n 9541) were randomized to receive either 10 mg of ramipril or placebo in additio...
متن کاملNeurotrophins – More than Neurotrophic
The Nerve Growth Factor (NGF) is the prototypic member of the neurotrophin (NT) family, which plays an essential role in the development and functioning of the vertebrate nervous system. Although originally defined by their actions on neuronal survival and differentiation in the peripheral (PNS) and central nervous systems (CNS), accumulating data indicate the presence of extensive interactions...
متن کاملMore than a diagnosis.
As educated women, we were bewildered by our medical care, or lack thereof. Following prenatal diagnostics of trisomy 13 or 18, we chose to continue our pregnancies. We understood that our babies would most likely die in utero or soon after birth. To enable ourselves to make informed choices, we sought information from the internet. Here, it was discovered that some babies with these trisomies ...
