Пространственная организация населения птиц Притымья

Пространственная организация населения птиц Притымья

Abstract

Изучено весенне-летнее население птиц Притымья – ранее мало исследованного в орнитологическом отношении района Западной Сибири. На основе полученных классификационных и структурных представлений о пространственном разнообразии орнитокомплексов установлены основные тенденции их территориальных изменений. Плотность населения птиц возрастает при смене темнохвойных пород мелколиственными, воздействии пойменного режима, снижении облесенности, возрастании мозаичности и продуктивности биоценозов. Уменьшение суммарного обилия птиц прослеживается при обеднении минерального питания и упрощении ярусной структуры фитоценозов, олиготрофном заболачивании, уменьшении облесенности и продуктивности биоценозов. Наибольшие показатели видового богатства отмечены в темнохвойных и смешанных лесах, на вырубках и верховых болотах. Средние значения характерны для сосняков, мелколиственных лесов и закустаренных лугов и минимальные – для мезотрофных болот. Наличие поселков определяет уменьшение видового богатства и увеличение суммарного обилия за счет синантропных видов. При смене наземных местообитаний водными в сообществах птиц уменьшается число видов и особей.
