Se suele afirmar, quizás en base a la evidencia de tanto hueco interno como presentan, que los muertos carecen de vida interior. Pero los que los han tratado sostienen, de acuerdo con su experiencia empírica, justamente lo contrario. Así, desnudos de todo lo que la civilización conlleva, se nos muestran tal como son. Quizás en este desfase radique eso que los expertos llaman humor negro y que Ermengol con tanto talento ejemplifica en el ataúd tan excelentemente dibujado que ustedes tienen entre manos.

This volume summarises the outcome of the 13th Workshop of the International Association of Phytoplankton Taxonomy and Ecology (IAP) on if, and if so under what conditions phytoplankton assemblages reach equilibrium in natural environments. Quite a number of ecological concepts use terms such as: ecological equilibrium, stability, steady-state, climax, stable state, etc. However, these ecological concepts often have been "translations" of scientific theories developed in physics or chemistry but they almost always lack scientific corroboration, the problem being that often these concepts remain vague and they are not formally defined. Here an attempt to formally recognize what "equilibrium" is in phytoplankton ecology is traced. The book also contains papers by leading scientists on the taxonomy of two selected key groups: cryptomonads and filamentous cyanoprokaryotes. This volume is addressed to all those involved in phytoplankton taxonomy and ecology and in ecology itself.

As with nearly all living creatures, humans have always been attracted and intrigued by floral scents. Yet, while we have been manufacturing perfumes for at least 5000 years to serve a myriad of religious, sexual, and medicinal purposes, until very recently, the limitation of our olfactory faculty has greatly hindered our capacity to clearly and ob
