Hybrid Isolation Amps Zap Price and Voltage Barriers
ثبت نشده
چکیده
As three-chip hybrids, the amplifiers have from the start been designed to solve economically the problems that up to now have limited the use of off-the-shelf units. Key to keeping costs down is a capacitive-coupling approach to isolation. Any amplifiers so far available with the same capabilities are costly, enlisting magnetic or optical techniques to bridge the high-voltage barrier. Whether hybrids or modules, they are all multidevice circuits requiring complex assembly procedures.

Evolution of postzygotic reproductive isolation in a guild of deceptive orchids.
The evolution of reproductive barriers is of central importance for speciation. Here, we investigated three components of postzygotic isolation-embryo mortality, hybrid inviability, and hybrid sterility-in a group of food-deceptive Mediterranean orchids from the genera Anacamptis, Neotinea, and Orchis. In these orchids, pollinator-mediated isolation is weak, which suggests that postpollination ...
متن کاملEcological divergence associated with mating system causes nearly complete reproductive isolation between sympatric Mimulus species.
Speciation often involves the evolution of numerous prezygotic and postzygotic isolating barriers between divergent populations. Detailed knowledge of the strength and nature of those barriers provides insight into ecological and genetic factors that directly or indirectly influenced their origin, and may help predict whether they will be maintained in the face of sympatric hybridization and in...
متن کاملSpecificity in pollination and consequences for postmating reproductive isolation in deceptive Mediterranean orchids
The type of reproductive isolation prevalent in the initial stages of species divergence can affect the nature and rate of emergence of additional reproductive barriers that subsequently strengthen isolation between species. Different groups of Mediterranean deceptive orchids are characterized by different levels of pollinator specificity. Whereas food-deceptive orchid species show weak pollina...
متن کاملThe Rate of Evolution of Postmating-Prezygotic Reproductive Isolation in Drosophila
Reproductive isolation is an intrinsic aspect of species formation. For that reason, the identification of the precise isolating traits, and the rates at which they evolve, is crucial to understanding how species originate and persist. Previous work has measured the rates of evolution of prezygotic and postzygotic barriers to gene flow, yet no systematic analysis has studied the rates of evolut...
متن کاملPostmating reproductive barriers contribute to the incipient sexual isolation of the United States and Caribbean Drosophila melanogaster
The nascent stages of speciation start with the emergence of sexual isolation. Understanding the influence of reproductive barriers in this evolutionary process is an ongoing effort. We present a study of Drosophila melanogaster admixed populations from the southeast United States and the Caribbean islands known to be a secondary contact zone of European- and African-derived populations undergo...
