On the Immunity Coloration of Some Nudibranchs.
6. Finally in problems of thermodynamics, there would seem to be no valid objection to its use. In the characteristic equation for a pure gas, the product of the new reading and the gas constant give as before a measure of the kinetic energy of translation of the molecules. Similarly in Avogardo's law, we have an even more definite conception of the temperature function; and also in the Stefan-...

Aposematic (warning) coloration associated with thorns in higher plants.
Aposematic coloration, a well-known phenomenon in animals, has been given little attention in plants. Here I discuss two types of conspicuousness of thorns which are typical of many plant species: (1) colorful thorns, and (2) white spots, or white and colorful stripes, associated with thorns in leaves and stems. Both types of aposematic coloration predominate the spine system of taxa rich with ...
متن کاملCOMMENTARY Chemical or nematocyst - based defence in the nudibranch Cratena peregrina ? – A reply to B . K . Penney Arnaldo Marin
Aguado & Marin (2007) analysed the interaction between Cratena peregrina (Gmelin, 1791) and predatory fish in laboratory and field assays, using both live aeolids and artificial models. Penney’s comment (2009) on the article reopens the old question of the role of nematocyst-based defence in nudibranchs. Penney suggests that the defensive mechanism of C. peregrina is chemical because the nemato...
