Special Issue Information

Dear Colleagues,

As a vital resource for human existence and ecological systems, fresh water is of fundamental importance to every form of life. Several disciplinary areas, including zoology, behavioral science, botany, resources, and other biological sciences such as physiology, genetics, and molecular biology, share an interest in freshwater ecology. This topic is also closely related to environmental sciences including biogeography, geomorphology, limnology. Freshwater resource availability has been under threat from climate change and other human pressures such as hydropower use, emerging contaminants and species invasion in recent decades. Biological invasions pose a threat to biodiversity, ecological services, conservation and resource management. Invasive species show devastating impacts on the native community and ecosystem processes. Many characteristics that may contribute to the establishment of non-native species can enhance our understanding of the ecology of species invasions.

Our aim in launching this Special Issue is to provide a forum for the publication of innovative, original articles and reviews relating to the ecology of hydrobionts (algae, invertebrates, fish, benthos) and invasive species, particularly their distribution, population, zoology, behavior, genetics, physiology, adaptation, and biotic interactions. The scope of this Special Issue includes, but is not limited to: the evaluation of hydrobionts distribution patterns and their relationships with the water physicochemical environment, hydrobiont responses to the environment change, invasive species distributions and their responses the during invasion process, and short-term and long-term changes in the community that has been invaded. Understanding the distribution of hydrobiology and invasive species will lead to improved freshwater resource management and, ultimately, its sustainable development and utilization.

The Alligator Gar (Atractosteus spatula) is a very dangerous species that has an extremely destructive impact on the ecological environment in aquatic areas. As a kind of ornamental fish, it is spreading rapidly all over the world. In order to avoid or delay the spread of Alligator Gar in China, it is urgent to further monitor and clarify its distribution range within the country. In this study, a maximum entropy model (MaxEnt) and geographical information system (ArcGIS) were used to identify suitable regions under climate change scenarios in China, and the significance of environmental factors that shape this species’ distribution were evaluated. According to the geographical distribution data of Alligator Gar and selected environmental variables, the potential habitat area of Chinese Alligator Gar under four climate scenarios in the present (2000s) and future (2050s and 2070s) was predicted. (1) The main environmental variables affecting the potential geographical distribution of Alligator Gar are temperature factor variables (the mean temperature of the warmest quarter and the mean temperature of the coldest quarter), precipitation factor variables (precipitation in the driest month and in the driest quarter), and altitude. (2) Under the current climate conditions, the suitable breeding areas of Alligator Gar are mainly concentrated in the Guangxi Zhuang Autonomous Region, Guangdong Province, and Hainan Province. Under the four future climate scenarios, the distribution area of the total suitable area of Alligator Gar will gradually decrease, and the suitable area of Alligator Gar will spread to high latitudes.
