Ojectifs MEIOSE: Expliquer la division réductionnelle et la division équationnelle 1- La reproduction Qu’est-ce que la reproduction? C’est la capacité d’un être vivant d’engendrer d’autres êtres vivants qui lui ressemblent, perpétuant ainsi son espèce. La reproduction distingue l’être vivant du monde non-vivant.

Introduction to algebraic geometry

Algebraic geometry, central to pure mathematics, has important applications in such fields as engineering, computer science, statistics and computational biology, which exploit the computational algorithms that the theory provides. Users get the full benefit, however, when they know something of the underlying theory, as well as basic procedures and facts. This book is a systematic introduction to the central concepts of algebraic geometry most useful for computation. Written for advanced undergraduate and graduate students in mathematics and researchers in application areas, it focuses on specific examples and restricts development of formalism to what is needed to address these examples. In particular, it introduces the notion of Gröbner bases early on and develops algorithms for almost everything covered. It is based on courses given over the past five years in a large interdisciplinary programme in computational algebraic geometry at Rice University, spanning mathematics, computer science, biomathematics and bioinformatics.

Bird Migration and Global Change

Changes in seasonal movements and population dynamics of migratory birds in response to ongoing changes resulting from global climate changes are a topic of great interest to conservation scientists and birdwatchers around the world. Because of their dependence on specific habitats and resources in different geographic regions at different phases of their annual cycle, migratory species are especially vulnerable to the impacts of climate change.?In Bird Migration and Global Change, eminent ecologist George W. Cox brings his extensive experience as a scientist and bird enthusiast to bear in evaluating the capacity of migratory birds to adapt to the challenges of a changing climate.?Cox reviews, synthesizes, and interprets recent and emerging science on the subject, beginning with a discussion of climate change and its effect on habitat, and followed by eleven chapters that examine responses of bird types across all regions of the globe. The final four chapters address the evolutionary capacity of birds, and consider how best to shape conservation strategies to protect migratory species in coming decades.?The rate of climate change is faster now than at any other moment in recent geological history. How best to manage migratory birds to deal with this challenge is a major conservation issue, and Bird Migration and Global Change is a unique and timely contribution to the literature.

THE IMMORTAL LIFE OF HENRIETTA LACKS

The book talks about Henrietta Lacks and the immortal cell line, known as HeLa, from Lacks' cervical cancer cells in 1951. Skloot became interested in Lacks after a biology professor mentioned, but did not know her much. Skloot began conducting extensive research on her and worked with the Lacks family to create the book. The book is notable for its scientific writing and treating ethical issues of race and class in medical research. Skloot said some of the information came from the diary of Deborah Lacks, daughter of Henrietta Lacks, as well as "photos and archival documents, scientific and historical research ". This is Skloot's first book.
