Abstract
Fish can act as dispersal vectors for many plant species, and this mutualistic relationship is critical for structuring and regeneration in Amazonian floodable forests. However, anthropogenic threats, such as the deforestation of floodable forests and the overfishing of some species, can disrupt this mutualistic interaction. We investigated the relationship between the size of fish that consume fruits and seeds and the size of seeds retrieved from the fish in the floodable forests. We hypothesize that, in floodable forests, fish with larger body size disperse the larger seeds. A total of 1,054 seeds from 16 plant species were found in the digestive tracts of nine species of frugivorous fish. The length and weight of the fish were positively related with the size of the seeds found in the digestive tracts. The reduction in fish abundance and size may affect dispersal and regeneration, especially of species with larger seeds. Considering the diverse threats to interactions between fish and Amazonian forested wetlands, our study highlights the importance of adequate management of fishery resources and floodable forests for the maintenance of ecosystem services of these environments in the region.
期刊介绍：
Wetlands is an international journal concerned with all aspects of wetlands biology, ecology, hydrology, water chemistry, soil and sediment characteristics, management, and laws and regulations. The journal is published 6 times per year, with the goal of centralizing the publication of pioneering wetlands work that has otherwise been spread among a myriad of journals. Since wetlands research usually requires an interdisciplinary approach, the journal in not limited to specific disciplines but seeks manuscripts reporting research results from all relevant disciplines. Manuscripts focusing on management topics and regulatory considerations relevant to wetlands are also suitable. Submissions may be in the form of articles or short notes. Timely review articles will also be considered, but the subject and content should be discussed with the Editor-in-Chief (NDSU.wetlands.editor@ndsu.edu) prior to submission. All papers published in Wetlands are reviewed by two qualified peers, an Associate Editor, and the Editor-in-Chief prior to acceptance and publication. All papers must present new information, must be factual and original, and must not have been published elsewhere.
