Особенности популяционной структуры поселения ушастой круглоголовки, Phrynocephalus mystaceus (Pallas, 1776) (Lacertilia: Agamidae) на песчаном массиве Сарыкум

Представлены результаты исследования популяционной структуры поселения ушастой круглоголовки, Phrynocephalus mystaceus mystaceus (Pallas, 1776) на песчаном массиве Сарыкум (43°00'23.9 с.ш., 47°14'04.3 в.д.). Цель исследования – выяснение особенностей популяционной структуры вида в условиях островного обитания на изолированной песчаной территории. Специфичностью поселения вида на Сарыкуме являлась очень высокая плотность населения, в среднем составлявшая 82.1 особ./га, относительно небольшая средняя величина индивидуальных участков (в среднем 69.7±33.3 и 50.7±35.9% у самцов и самок соответственно) и их значительное перекрывание: внутри половых групп (57.5±39.4% у самок с участками самцов). Перекрывание участков внутри группы молодняка оказалось достоверно больше – 93.2±12.9%. Особенностью поселения являлось и преобладание в оседлой части неполовозрелых особей (1.7:1), 1–2-дневные участки которых перемещались по территории поселения. Последнее, вероятно, связано со стремлением молодняка закрепиться в любой части перенаселенной территории. По площади поселения шел поток мигрантов, равный 25.7 особ./га в неделю, состоящий в равных частях из половозрелых и неполовозрелых животных. Неполное перекрывание участков самок с участками самцов можно рассматривать как возможный элемент начала работы механизмов авторегуляции численности, уменьшающий число встреч половых партнеров. Все специфические черты поселения, по всей видимости, связаны с островным положением популяции.
