Why don't you give exact delivery time?
Delivery time is estimated on our previous experiences. We give estimations only, because we order from outside Hungary, and the delivery time mainly depends on how quickly the publisher supplies the book. Faster or slower deliveries both happen, but we do our best to supply as quickly as possible.

Short description:
This book proposes a new approach to population biology and ecology. The current paradigm for analyzing population dynamics focuses attention on the growth rate as the main variable responding to the environment, and leads often to predictions of runaway acceleration seldom actually seen in nature. This book proposes and develops an inertial view of population growth, taking note of acceleration, or rate of change of the growth rate between consecutive generations, which allows a simpler model for complex population dynamics, often without invoking species interations, that appears to fit the actual outcomes better than traditional Lotka-Volterra modeling. The maternal effect is presented as a major driver for this shift in modeling orientation. Investment of mothers in the quality of their daughters makes the rate of reproduction depend not only on the current environment, but also on the environment experienced by the previous generation. Ginzburg is a highly respected ecologist, and this book should be read by most population biologists and ecological modellers and by theoretical biologists and philosophers of science.
MoreLong description:
A famous ecologist and a philosopher of science team up to offer a fresh new approach to population biology and ecology. Challenging the traditionally accepted Lotka-Volterra model, which is based on predator-prey interactions, this new model emphasizes maternal effects, specifically the significance of a mother's interest in the success of her female offspring.
...the book is stimulating and undoubtedly has an important message to convey... Steohen Hoskins, The Biologist, October 2006.
