Abstract

The composition of soil, ground litter, and litterfall water extracts was studied for zones affected by gray heron nesting places and for background sites covered by broad-leaved forests in the gray forest soil zone of Tula oblast. It is established that birds’ activities result in an inflow of bird excreta, formation of specific forest ground litters, and increase in the share of large-size tree litter that accumulates in the course of nest building. It is shown that ground litter, litterfall, and upper horizons of the gray forest soil in nesting places feature higher concentrations of macroelements (calcium, potassium, and magnesium), microelements (copper, zinc, and strontium), and anions (NO\(_{3}^{ - }\), PO\(_{4}^{{3 - }}\), and Cl⁻).

图拉州灰鹭（Ardea cinerea L.）筑巢地对陆生凋落物和土壤动态变化性质的影响

摘要

研究了图拉州灰色森林土壤带中受灰鹭筑巢处影响的区域和阔叶林覆盖的背景点的土壤，地面凋落物和凋落物水提取物的组成。可以确定，鸟类的活动会导致鸟类排泄物的流入，特定森林地面垃圾的形成，以及在筑巢过程中积累的大型树木垃圾的份额增加。结果表明，筑巢地的凋落物，凋落物和灰色森林土壤的上层地平线具有较高浓度的常量元素（钙，钾和镁），微量元素（铜，锌和锶）和阴离子（NO \（ _ {3} ^ { - } \），PO \（_ {4} ^ {{3 - }} \），和Cl ^-）。
