Not so hot "hot spots" in the oceanic mantle.
Excess volcanism and crustal swelling associated with hot spots are generally attributed to thermal plumes upwelling from the mantle. This concept has been tested in the portion of the Mid-Atlantic Ridge between 34 degrees and 45 degrees (Azores hot spot). Peridotite and basalt data indicate that the upper mantle in the hot spot has undergone a high degree of melting relative to the mantle else...

متن کاملHot and not-so-hot females: reproductive state and thermal preferences of female Arizona Bark Scorpions (Centruroides sculpturatus).
For ectotherms, environmental temperatures influence numerous life history characteristics, and the body temperatures (Tb ) selected by individuals can affect offspring fitness and parental survival. Reproductive trade-offs may therefore ensue for gravid females, because temperatures conducive to embryonic development may compromise females' body condition. We tested whether reproduction influe...
متن کاملDounreay hot particles: the story so far.
The first Dounreay hot particle (hereafter 'Particle') to be formally identified was recovered from the Dounreay foreshore in 1983. A further single Particle was recovered from Sandside beach the following year. Particles have been detected and removed from the Dounreay foreshore regularly since 1984 and from the offshore sediments since 1997. Since 1997, an extensive research and development p...
متن کاملWhat's So Hot about Recombination Hotspots?
C onsider a piece of text, either this one that you are now reading or any other. Surely they are all pretty much alike, in so far as they are all run-on strings of characters. In this same sense, we can envision that all DNA strands are alike because all are monotonous polymers with the same general chemical makeup. Indeed, this is how we think of DNA when considering its basic function of inh...
