Abstract
This study characterizes a population of the rare seagrass species Halophila baillonii, rediscovered over 130 years after its initial record on the Brazilian coast. Historical and current global distribution and species traits were reviewed to investigate population expansion and compare worldwide populations. Generally, seagrass traits of this new population showed no significant differences compared to previously studied populations, including those within Marine Protected Areas. However, a global lack of population data for the species was identified. Thirteen populations were recognized within the Tropical Atlantic Bioregion, with most in multispecific meadows. In these multispecific meadows, H. baillonii leaves were wider. The recent rediscovery of this population raises the question: are we observing a genuine expansion of its distribution range, or have we simply overlooked its presence in certain areas?
期刊介绍:
Aquatic Botany offers a platform for papers relevant to a broad international readership on fundamental and applied aspects of marine and freshwater macroscopic plants in a context of ecology or environmental biology. This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences of disturbance and stressors (e.g. environmental fluctuations and climate change, pollution, grazing and pathogens), use and management of aquatic plants (plant production and decomposition, commercial harvest, plant control) and the conservation of aquatic plant communities (breeding, transplantation and restoration). Specialized publications on certain rare taxa or papers on aquatic macroscopic plants from under-represented regions in the world can also find their place, subject to editor evaluation. Studies on fungi or microalgae will remain outside the scope of Aquatic Botany.
