I first became involved in research into primate behavior and
ecology in 1968, over 40 years ago, driven by a quest for a better
understanding of the natural context of primate evolution. At that
time, it was virtually unknown that primates can exploit exudates
as a major food source. I was certainly unaware of this myself. By
good fortune, I was awarded a postdoctoral grant to work on lemurs
with Jean-Jacques Petter in the general ecology division of the
Museum National d'Histoire Naturelle in Brunoy, France. This
provided the launching-pad for my first field study of lesser mouse
lemurs in Madagascar, during which I gained my initial inklings of
exudate feeding. It was also in Brunoy that I met up with Pierre
Charles- Dominique, who introduced me to pioneering observations of
exudate feeding he had made during his field study of five
lorisiform species in Gabon. This opened my eyes to a key feeding
adaptation that has now been reported for at least 69 primate
species in 12 families (Smith, Chap. 3) - almost 20% of extant
primate species. So exudativory is now firmly established as a
dietary category for p- mates, alongside the long-recognized
classes of faunivory (including insectivory), frugivory, and
folivory. Soon after I encountered Charles-Dominique, he published
the first synthetic account of his Gabon field study in a French
language journal (Charles-Dominique 1971).
The Atlantic Forest is one of the 36 hotspots for biodiversity
conservation worldwide. It is a unique, large biome (more than 3000
km in latitude; 2500 in longitude), marked by high biodiversity,
high degree of endemic species and, at the same time, extremely
threatened. Approximately 70% of the Brazilian population lives in
the area of this biome, which makes the conflict between
biodiversity conservation and the sustainability of the human
population a relevant issue. This book aims to cover: 1) the
historical characterization and geographic variation of the biome;
2) the distribution of the diversity of some relevant taxa; 3) the
main threats to biodiversity, and 4) possible opportunities to
ensure the biodiversity conservation, and the economic and social
sustainability. Also, it is hoped that this book can be useful for
those involved in the development of public policies aimed at the
conservation of this important global biome.
Integrating advances in molecular biology into bioprocesses
presents a continuous challenge to scientists and bioengineers.
This series is conceived to help meet this challenge. It examines
and assesses the feasibility of new approaches for the modification
of cellular function such as gene expression, protein processing,
secretion, glycosylation, immortalisation, proliferation, and
apoptosis as well as the systematic study of the metabolic
genotype-phenotype relationship. The series provides detailed
coverage of the methodology for improving cellular properties of
cells used in the production of biopharmaceuticals, gene and cell
therapies and tissue engineering. It also seeks to explain the
cellular mechanisms underlying in vitro physiological activity and
productivity. This volume, which is based on presentations at the
European Workshop on Animal Cell Engineering' held in Costa Brava,
Spain, contains a collection of chapters relating to cellular
function and modification by leading authorities in several
different areas of basic research and the biopharmaceutical
industry.
Although biological exploration in Surinam started about 300 years
ago, a thorough account of the Surinam herpetofauna has not
hitherto been publish ed. Several publications on the subject have
been issued (see below), but none of them was comprehensive.
However, there are several papers dealing with a part of the
Surinam lizards. The main reason for the absence of a complete
review of the Surinam lizards (and, for that matter, of the entire
herpeto fauna) has been the scarcity of the material available in
museum collection although some of the more common species reached
museums in considerable numbers. Until about 1900 the interior of
Surinam was virtually terra incognita and most collecting took
place in a restricted, cultivated area along the coast and the
farthest inland point reached was Berg en Dal on the Suriname
River. From 1900 exploration of the interior was actively
encouraged by the Dutch Government, and under the auspices of the
Koninklijk Nederlandsch Aard rijkskundig Genootschap several
geographical expeditions explored the main river systems. Although
the main purpose of these expeditions was to map the visited areas,
usually the physician accompanying the expedition was entrusted
also with the collecting of zoological and botanical specimens.
Interesting ma terial from the interior started to reach the Dutch
museums in ever increasing numbers after the late nineteen thirties
when Dr. D. C. GEIJSKES arrived in Su rinam. The Surinam Expedition
1948-49 in which Dr. GElJSKES and Mr. P. H."
The book consists of multiple chapters by leading experts on the
different aspects in the unique relationship between arthropods and
plants, the underlying mechanisms, realized successes and failures
of interactions and application for IPM, and future lines of
research and perspectives. Interesting is the availability of the
current genomes of different insects, mites and nematodes and
different important plants and agricultural crops to bring better
insights in the cross talk mechanisms and interacting players. This
book will be the first one that integrates all this fascinating and
newest (from the last 5 years) information from different leading
research laboratories in the world and with perspectives from
academia, government and industry.
With the invitation to edit this volume, I wanted to take the
opportunity to assemble reviews on different aspects of circadian
clocks and rhythms. Although most c- tributions in this volume
focus on mammalian circadian clocks, the historical int- duction
and comparative clocks section illustrate the importance of various
other organisms in deciphering the mechanisms and principles of
circadian biology. Circadian rhythms have been studied for
centuries, but only recently, a mole- lar understanding of this
process has emerged. This has taken research on circadian clocks
from mystic phenomenology to a mechanistic level; chains of
molecular events can describe phenomena with remarkable accuracy.
Nevertheless, current models of the functioning of circadian clocks
are still rudimentary. This is not due to the faultiness of
discovered mechanisms, but due to the lack of undiscovered
processes involved in contributing to circadian rhythmicity. We
know for example, that the general circadian mechanism is not
regulated equally in all tissues of m- mals. Hence, a lot still
needs to be discovered to get a full understanding of cir- dian
rhythms at the systems level. In this respect, technology has
advanced at high speed in the last years and provided us with data
illustrating the sheer complexity of regulation of physiological
processes in organisms. To handle this information, computer aided
integration of the results is of utmost importance in order to d-
cover novel concepts that ultimately need to be tested
experimentally.
