拟柱孢藻(Cylindrospermopsis raciborskii)生态学研究现状与面临的挑战
State of the art and challenges of Cylindrospermopsis raciborskii ecology
摘要
Abstract
Cylindrospermopsis raciborskii is widely distributed in the tropics and is considered to be a tropical or pantropical species capable of producing multiple toxins.In the last three decades,the distri-bution of the species has shown a strong trend of"spreading"on a global scale,and it has been widely occurring in many water bodies in Europe,North America and Asia.Nowadays,the species has been widely found in China,and is abundant in many lakes and reservoirs,especially in those for drinking water supply in southern China.It has been reducing water supply safety and largely impaired aquatic ecosystem health.In the lowland reservoirs of the Pearl River basin,the species has become the most dominant cyanobacterial species.It is predicted that C.raciborskii will become the second most harmful cyanobacteria species in China's fresh water after Microcystis spp.In order to avoid the dilemma similar to passive response to heavy Microcystis blooms in the country scale,it is required to carry out a prospective ecological study based on modern ecological concepts,and to understand the biological and ecological basis of its rapid and large-scale occurrence and dominance.In this review,the expan-sion mechanism,competitive advantage at population level and its impact on aquatic ecosystems were commented from the perspective of biogeography and population ecology.We summerised phosphorus uptake mechanisms by the species and its adaptability to tropical aquatic environment.Under global climate warming,the Pearl River Basin and its adjacent areas will function as the"seed"source area for the species to diffuse northward.The species will take advantage of the Yunnan-Guizhou Plateau as a stepping-stone to enter the Yangtze River basin and further spread to higher latitudes.So,we empha-size that the Pearl River Basin and its adjacent areas are the critical area for the study of C.raciborskii in both East Asia and the global scale.We strongly suggest to carry out interdisciplinary approaches to the ecology of C.raciborskii for formulating national monitoring programs,controlling methods and management strategies.关键词
