AbstractInvestigating the composition of food sources with stable isotope method can provide direct evidence for the top-down control in the coastal wetland.In this study,we examined food source and feeding habit of Helice tientsinensis of common reed (Phragmites australis) vegetation in high marsh of Yellow River Delta.The results showed that the density of crab was (5.5 1.5) ind·m~(-2),with the behavior of climbing P.australis to feed on the leaves at night.Under the same indoor experimental condition,H.tientsinensis showed feeding preference on fresh leaves of P.australis.The stable isotope food source analysis showed that the leaves of P.australis were one of the important food sources of H.tientsinensis in the field.There were temporal variations in the proportion of fresh leaves [May:(6.44.9) %,July:(5.84.9) %,September:(12.58.8) %] and dead leaves [May:(12.47.8) %,July:(15.59.9) %,September:(15.19.4) %].Therefore,H.tientsinensis could inhibit P.australis's growth and affect litter decomposition through feeding disturbance behavior.
Other Abstract通过稳定同位素方法,研究植物在大型底栖动物的食源占比,可以为滨海湿地下行效应提供直接证据。本文研究了黄河三角洲高潮滩芦苇区天津厚蟹的食性和食源。结果表明:该植被区蟹类密度为(5.51.5) ind·m~(-2),存在夜间攀爬芦苇取食的行为。在室内试验条件下,天津厚蟹具有明显的食物偏好,偏好取食芦苇新鲜叶片。通过稳定同位素食源分析发现,在野外自然环境下,芦苇叶片是天津厚蟹的重要食源之一。鲜叶[5月:(6.44.9) %;7月:(5.84.9) %;9月:(12.58.8) %]和枯叶[5月:(12.47.8) %;7月:(15.59.9) %;9月:(15.19.4) %]的食源占比均具有时间异质性。天津厚蟹不仅可能通过取食抑制芦苇生长,还可能通过取食的扰动行为影响该植被区的枯落物分解。
