A importância da ordem e tempo de chegada no efeito de prioridade: uma revisão sobre plantas aquáticas e terrestres.
The order and timing of the arrival of species at the beginning of colonization can alter the composition and functioning of naturally structured communities through the priority effect. Plant species that establish early can affect the establishment, growth or reproduction of species that arrive later. However, plants that inhabit terrestrial environments face different environmental conditions from those faced by aquatic plants, so the environment can also affect the success of plant colonization and establishment in different ways. Through a systematic review, we sought to understand how the priority effect has been studied through experimental and observational approaches, developed in terrestrial and aquatic environments. The experimental manipulation of the order of arrival of species can shed light on the mechanisms of community assembly and the biotic and abiotic conditions that affect the early or late establishment of species, while the observational approach provides answers as to the duration of the priority effect in the long term. To understand the state of the art of the priority effect in aquatic and terrestrial vegetation, a survey was carried out in the Web of Science and Scopus databases, which highlighted the importance of dispersal and suitable environmental conditions at the time of arrival. The priority effect could be seen on time scales ranging from days to years, and in some studies, it was able to be maintained over decades. However, the review pointed out that research into terrestrial environments is more advanced than that into aquatic environments, and it is necessary to prioritize this environment, which is still overlooked, to understand how the colonization and establishment of aquatic plants are affected in lentic and lotic environments and in wetlands, because the priority effect can act differently in the aquatic environment, caused by variations such as water speed. For example, while in the terrestrial environment the pre-emption of nutrients by priority species has been shown to be effective in inhibiting the growth of late species, in the aquatic environment the flow of water can make it difficult to limit this resource.
