Dwarf males are often found in species with sedentary females, where they typically cohabit in varying degrees of intimacy. This is short of true parasitism because, in return for room and board, males provide the benefit of sperm. Sexual selection rarely seems to be an option to explain male dwarfing, whereas natural selection often can.

Galaxies![Figure][1] An infrared image of the Large Magellanic Cloud CREDIT: ESA/NASA/JPL-CALTECH/STSCI Galaxies grow hierarchically: Small galaxies merge into bigger ones. Large galaxies like our Milky Way are surrounded by dozens of satellite dwarf galaxies, which are still in the process of merging.

Cereals can be infected by a vast range of pathogens of which Wheat dwarf virus (WDV, family Geminiviridae, genus Mastrevirus), the aetiological agent of wheat dwarf disease (WDD), is one of the most damaging of all. This chapter presents an overview of WDD, its causal agent, leafhopper vectors, diagnostic methods and available management strategies ...

Dwarf is a highly compressed structure for computing, storing, and querying data cubes. Dwarf identifies prefix and suffix structural redundancies and factors them out by coalescing their store. Prefix redundancy is high on dense areas of cubes but suffix redundancy is significantly higher for sparse areas.

Exposed white dwarfs in dwarf novae
2008Hubble Space Telescope far ultraviolet spectroscopic observations of cataclysmic variable white dwarfs, exposed during dwarf nova quiescence, have yielded a number of new insights on accretional heating, photospheric abundances of the accreted atmosphere and rotational velocities of the underlying degenerates.
