Коллективная монография посвящена средообразующей деятельности речного бобра – ключевого вида малых рек Приокско-Террасного заповедника. Изучение динамики численности и распределения бобров в водоемах заповедника проводится более 60 лет, с первых дней реинтродукции. Рассмотрены общие природные характеристики заповедника, включая климат, рельеф, гидрологическую сеть, характеристику флоры и фауны. Представлены особенности обитания речного бобра, включая детальное описание многолетней динамики численности с характеристикой изменения размещения поселений, строительной деятельности, особенностей кормодобывания, влияния хищников и вербальное описание изменения местообитаний на территории заповедника. Особое внимание уделено математическим моделям, предназначенным для выявления основных тенденций изменения численности и построения прогноза популяционной динамики с учетом особенностей экологии вида. Охарактеризованы различные аспекты влияния бобров на водные и околоводные экосистемы малой реки Таденки, даны количественные и качественные характеристики влияния деятельности бобра на зоопланктон, макрозообентос, размножение амфибий, динамику черноольшаника и высшую водную растительность в местообитаниях речного бобра. Обсуждаются потенциальные возможности применения космических снимков среднего (Landsat 7) и сверхвысокого (IKONOS, GeoEye-1) пространственного разрешения для картирования объектов жизнедеятельности бобров. Данная монография будет интересна и полезна широкому кругу ученых – зоологам, гидробиологам и ботаникам, специалистам, работающим на стыке геоматики и экологии. Знание средообразующей деятельности бобра важно для специалистов, работающих в области сохранения биологического разнообразия, заповедного дела и рыбного хозяйства, а также для студентов и аспирантов.
