This book is written for undergraduate students of ecol- ogy. We set out to introduce our readers to the beauty and importance of ecology, and to do so without overwhelm- ing or boring them with unnecessary detail. This is a tall order, and so when we began writing the Third Edition of Ecology, we kept our focus on two core principles: "Teach- ing comes First!" and "Less is More!" Ushbu kitob bakalavriat ekologiya talabalari uchun yozilgan. Biz o'quvchilarimizni ekologiyaning go'zalligi va ahamiyati bilan tanishtirishni maqsad qilganmiz va buni keraksiz tafsilotlarga berilmasdan yoki zeriktirmasdan amalga oshirishni maqsad qilganmiz. Bu juda katta tartib, shuning uchun biz Ekologiyaning uchinchi nashrini yozishni boshlaganimizda, biz ikkita asosiy tamoyilga e'tibor qaratdik: "Birinchi navbatda o'qitish!" va "Kamroq - ko'proq!"
