How the nature illustrations of a Renaissance polymath reflect his turbulent age This pathbreaking and stunningly illustrated book recovers the intersections between natural history, politics, art, and philosophy in the late sixteenth-century Low Countries. Insect Artifice explores the moment when the seismic forces of the Dutch Revolt wreaked havoc on the region's creative and intellectual community, compelling its members to seek solace in intimate exchanges of art and knowledge. At its center is a neglected treasure of the late Renaissance: the Four Elements manuscripts of Joris Hoefnagel (1542-1600), a learned Netherlandish merchant, miniaturist, and itinerant draftsman who turned to the study of nature in this era of political and spiritual upheaval. Presented here for the first time are more than eighty pages in color facsimile of Hoefnagel's encyclopedic masterwork, which showcase both the splendor and eccentricity of its meticulously painted animals, insects, and botanical specimens. Marisa Anne Bass unfolds the circumstances that drove the creation of the Four Elements by delving into Hoefnagel's writings and larger oeuvre, the works of his friends, and the rich world of classical learning and empirical inquiry in which he participated. Bass reveals how Hoefnagel and his colleagues engaged with natural philosophy as a means to reflect on their experiences of war and exile, and found refuge from the threats of iconoclasm and inquisition in the manuscript medium itself. This is a book about how destruction and violence can lead to cultural renewal, and about the transformation of Netherlandish identity on the eve of the Dutch Golden Age.

Insect Timing - Circadian Rhythmicity to Seasonality (Hardcover, 1st ed): D.L. Denlinger, J Giebultowicz, D.S. Saunders Insect Timing - Circadian Rhythmicity to Seasonality (Hardcover, 1st ed)
D.L. Denlinger, J Giebultowicz, D.S. Saunders
R3,813 Discovery Miles 38 130 Ships in 12 - 17 working days

Leading experts in the field bring together diverse aspects of insect timing mechanisms. This work combines three topics that are central to the understanding of biological timing in insects: circadian rhythms, photoperiodism, and diapause. The common theme underlining each of the contributions to this book is an understanding of the timing of events in the insect life cycle. Most daily activities (emergence, feeding, mating, egg laying, etc.) undertaken by insects occur at precise times each day. Likewise, seasonal events such as the entry into or termination from an overwintering dormancy (diapause) occur at distinct times of the year. This book documents such events and provides an up-to-date interpretation of the molecular and physiological events undergirding these activities.

The study of circadian rhythms has undergone a flowering in recent years with the molecular dissection of the components of the circadian clock. Now that many of the clock genes have been identified it is possible to track daily patterns of clock-related mRNAs and proteins to link the entraining light cycles with molecular oscillations within the cell. Insect experiments have led the way in demonstrating that the concept of a "master clock" can no longer be used to explain the temporal organization within an animal. Insects have a multitude of cellular clocks that can function independently and retain their function under organ culture conditions, and they thus offer a premier system for studying how the hierarchical organization of clocks results in the overall temporal organization of the animal. Photoperiodism, and its most obvious manifestation, diapause, does not yet have the molecular underpinning that has been established for circadian rhythms, but recent studies are beginning to identify genes that appear to be involved in the regulation of diapause. Overall, the book presents the rich diversity of challenges and opportunities provided by insects for the study of timing mechanisms.
