Twenty-three rocky shores along approximately 225 km on the southwest coast of the Bay of Biscay were sampled during the springs of 2014 and 2021, to explore changes in the distribution and abundance of four non-indigenous species (NIS) macroalgae (i.e., Asparagopsis armata, Grateloupia turuturu, Sargassum muticum, and Undaria pinnatifida) by using a semi-quantitative scale. Results showed relevant

Habitat requirements of Myriophyllum alterniflorum DC. in river stands of the Upper Palatinate Forest, Bavaria Aquat. Bot. (IF 1.8) Pub Date : 2023-06-24 Julia Sattler, Peter Poschlod
Biodiversity loss is, at present, one of the most severe global environmental issues. However, more demanding species are put at greater risk than generalists. Knowledge of the habitat requirements of threatened species is essential for defining the levels at which nature conservation efforts should prospectively operate. This study describes the habitat niche of the macrophyte species Myriophyllum

Biology and ecology of Pontederia crassipes in a Mediterranean river in Lebanon Aquat. Bot. (IF 1.8) Pub Date : 2023-06-26 Y. Ghoussein, H. Abou Hamdan, A. Fadel, J. Coudreuse, H. Nicolas, G. Faour, J. Haury
Invasive aquatic plants are considered the second cause of biodiversity loss in aquatic ecosystems. Pontederia crassipes Mart., formerly Eichhornia crassipes (Mart.) Solms (water hyacinth) is one of the most dangerous invasive species in the world. Since 2006, P. crassipes has invaded Lebanon’s Al Kabir River, causing ecological and socio-economic problems. To solve them, ecological and biological

Genetic and epigenetic variation of Trapa bispinosa under slope gradient: A case study in a subtropical freshwater lake Aquat. Bot. (IF 1.8) Pub Date : 2023-06-28 Yixian Li, Xuyao Zhao, Manli Xia, Hongwei Hou
Dynamic environmental factors can influence the genetic diversity and epigenetic variation of aquatic plants, thus accelerate the rate of species adaptations. Trapa bispinosa is an aquatic crop which is widely distributed in China and worldwide, yet little is known about the genetic and epigenetic variations of T. bispinosa in fishery and nature habitats. By using AFLP and MSAP, we analyzed the genetic

Distribution and diversity of the sympatric macroalgae of the pelagic Sargassum horneri in the Yellow and East China seas Aquat. Bot. (IF 1.8) Pub Date : 2023-06-26 Yong-Juan Liu, Jie Xiao, Shi-Liang Fan, Xiao-Xiang Miao, Chao Yuan, Yu Zang, Zong-Ling Wang, Bao-Tang Zhang, Xiao-Jun Ma, Xue-Lei Zhang
The massive pelagic Sargassum horneri (Turner) C. Agardh, 1820 has increasingly occurred in the Yellow Sea and East China Sea. Significant intrusion of floating S. horneri into the southwestern Yellow Sea, the major bloom region of the green tides, has aroused speculations on the blooming mechanism and confounded concurrent prevention practices of green tides. The floating S. horneri were surveyed

Threatened aquatic plant Aldrovanda vesiculosa L.: A review of its discovery and extinction in Japan Aquat. Bot. (IF 1.8) Pub Date : 2023-06-26 Hiro Shimai, Takehiro Ohmori
Aldrovanda vesiculosa L. (Droseraceae), or waterwheel plant, is a threatened aquatic plant species, and it is quickly vanishing from the natural distribution range in the world. There used to be many localities of the species in Japan, but it was extinct from nature in the country in 1967. The information regarding the localities in Japan was recorded in various sources, but those had not been summarized

Restoration of seagrass habitats: Effects of artificial and natural sediments on the development of transplanted eelgrass (Zostera marina) Aquat. Bot. (IF 1.8) Pub Date : 2023-06-15 Ingvild Fladvad Størdal, Embla Vildalen Uleberg, Diress Tsegaye, Jonathan E. Colman
Near-shore areas face multiple stressors, effects of climate change, coastal construction and contamination. Although capping the seabed in these areas with mineral masses can reduce the impact of legacy contaminants in sediment, it can also result in the loss of flora and sessile fauna, both of which are vital components of near-shore ecosystems. Eelgrass (Zostera marina) is essential to marine near-shore
