Article
Full-text available
Damming usually modifies riverine habitats, which affects various aspects of fish diversity, especially in a reservoir cascade. Their influence on fish assemblage has been studied widely, but a lack of data from the diversity perspective remains. The Gezhouba Reservoir and Three Gorges Reservoir are two of the largest cascaded reservoirs located on...

Shortjaw tapertail anchovy, Coilia brachygnathus, has invaded and expanded in the Three Gorges Reservoir (TGR) over the last few years. The population size and biological characteristics related to this invasion are poorly understood. To investigate its invasion mechanisms, we studied spatial and temporal changes in C. brachygnathus biomass and abu...
Article
To understand how riverine fish respond to longitudinally different habitats created by impoundment, we selected three congeneric yellow catfish species (Pelteobagrus spp.) as a model system to assess changes in diet, prey selectivity, and body condition among the lotic, transitional, and lentic habitats along the Three Gorges Reservoir. Our result...
Article
Riverine floodplains are biologically diverse and productive ecosystems. Although tropical floodplains remain relatively conserved and ecologically functional compared to those at higher latitudes, they face accelerated hydropower development, climate change, and deforestation. Alterations to the flood pulse could act synergistically with other dri...
Article
Frugivorous fishes switch their diets seasonally in response to fluctuating food availability; a strategy that maximizes energy and nutrient intake and reduces competition for food. Kleptoparasitism is a form of competition that involves the stealing of already‐procured items, for which the host has invested energy in prey capture. We did not find...
Article
Atlantic white-cedar (Chamaecyparis thyoides [L.] B.S.P.) is considered critically imperiled across much of its range. This species occurs in freshwater swamps, rarely further inland than 160 km from the Atlantic or Gulf Coasts and is susceptible to several natural and anthropogenic disturbances (i.e., tropical cyclones, fire, saltwater inundation,...
Article
The composition of land‐use/land cover (LULC) in coastal watersheds has many implications for estuarine system ecological function. LULC can influence allochthonous inputs and can enhance or degrade the physical characteristics of estuaries, which in turn affects estuaries’ abilities to support local biota. However, these implications for estuaries...
Article
Full-text available
Migratory species are the most important commercial fishes in the Amazon. They are also now the most threatened directly by some combination of overfishing, floodplain deforestation, and dam construction. Limited governmental monitoring and implemented regulations impede adequate management of the fisheries at adequate scale. We summarize the curre...
Chapter
Full-text available
Amazonian lowland tropical rainforests cover ~5.79 million km2. Based on geology, the Amazon lowland forest area can be divided into six regions. The Guiana Shield and Brazilian Shield (in the southern Ama- zon) are on very old, nutrient-poor soils, while the Western Amazonian regions (northern and southern) and the regions along the Amazon River a...
Article
en Our experiment revealed unexpected behavioral strategies involved in seed predation of Mabea fistulifera by fish (Brycon cephalus), including temporal storage of seeds in the stomach followed by regurgitation and reingestion of individual seeds. Larger fish were faster at removing the seed coat and exposing the endosperm, due to precise oral man...
Article
Many frugivorous animals act simultaneously as seed predators and dispersers, and shifts in the abundance and mean phenotype of the frugivore population can alter the prevalence of antagonistic vs mutualistic interactions with seeds. Here, we evaluated how a reduction in the abundance and species richness of large‐bodied frugivorous fishes affects...
Article
Passage through the digestive tract of frugivorous vertebrates likely influences seed dormancy, time to germination, and/or future seedling growth. Effects of gut passage on seed germination have been extensively investigated among frugivorous birds and mammals, however, few studies have focused on frugivorous fish. Here we present the results of a...

Full-text available
Abstract Amazonian waters are classified into three biogeochemical categories by dissolved nutrient content, sediment type, transparency, and acidity—all important predictors of autochthonous and allochthonous primary production (PP): (1) nutrient-poor, low-sediment, high-transparency, humic-stained, acidic blackwaters; (2) nutrient-poor, low-sedim...
Article
A frugivoria é um hábito de alimentação generalizado entre os peixes, particularmente nas zonas úmidas tropicais da América do Sul. Essa antiga interação evoluiu há cerca de 70 milhões de anos e, provavelmente, contribuiu para moldar comunidades de plantas em zonas úmidas neotropicais. Após quase quatro décadas de pesquisa, estamos apenas começando...
Article
en The diets of frugivorous animals result from the interaction between feeding preference and ecological factors such as availability of alternative resources and interactions with other frugivores. A better understanding of frugivore diets will enable predictions about the vulnerability of plant populations to anthropogenic or natural environment...
Article
Full-text available
The construction of the Three Gorges Reservoir (TGR), the largest dam in the world, created novel spatial and seasonal fluctuations in food availability along the Yangtze River. We studied changes in diet and niche overlap of three co-occurring catfish species between the upper and lower sections of the TGR and across four hydrological seasons to i...

Full-text available
To study how fish assemblages changed at different fillings stages, we compared the present fish assemblages (2015–2017; after the third filling in 2009) with those from periods prior to impoundment (1975), after the first closure (1997–2000), after the first filling (2005–2006), and after the second filling (2006–2009) in the upper, middle and low...
Article
Full-text available
Despite low in situ primary productivity, tropical oligotrophic rivers support highly diverse fish assemblages and productive fisheries. This raises the question, what energy sources support fish production in these ecosystems? We sampled fish and food resources in the floodplain of a nearly pristine, large, oligotrophic river in western Amazonia....
Article
Adjacent floodplain and upland tropical forests experience the same temperature and precipitation regimes, but differ substantially in plant species composition and biotic interactions because of extensive flooding. We hypothesize that flooded forests filter fruiting traits linked to seed dispersal by water and fishes, such that selection by water...
Article
Full-text available
Large fish are often the most effective seed dispersers, but they are also the preferred target for fisheries. We recently started to comprehend the detrimental impacts of the extirpation of large frugivorous fish species on natural forest regeneration, but we lack a general understanding of how intraspecific size-selective harvest affects fish–fru...
Article
Full-text available
When species within guilds perform similar ecological roles, functional redundancy can buffer ecosystems against species loss. Using data on the frequency of interactions between fish and fruit, we assessed whether co-occurring frugivores provide redundant seed dispersal services in three species-rich Neotropical wetlands. Our study revealed that f...

Full-text available
Isotopic variation within food sources adds uncertainty to models intended to reconstruct trophic pathways. Understanding this variation is pivotal for planning sampling protocols for food-web research. This study investigates natural variation in C and N stable isotopes among plant species in two western Amazon flooded forests with contrasting wat...
Article
This paper presents a standardized protocol for the non-lethal capture of fishes, sampling of stomach contents and quantification of seed dispersal efficiency by frugivorous fishes. Neotropical pacu Piaractus mesopotamicus individuals were collected with fruit-baited hooks. The diets of 110 fish were sampled using a lavage method, which retrieved >...
Article
Full-text available
Frugivorous fish play a prominent role in seed dispersal and reproductive dynamics of plant communities in riparian and floodplain habitats of tropical regions worldwide. In Neotropical wetlands, many plant species have fleshy fruits and synchronize their fruiting with the flood season, when fruit-eating fish forage in forest and savannahs for peri...
Article
Full-text available
Introduction of fish species is a globally widespread practice that causes losses of native species and homogenization of diversity within and across continents. Diet assessments are important tools to depict the ecological function of species introduced into novel ecosystem and possible direct and indirect ecological effects. In this study, we com...
Article
Full-text available
In response to temporal changes in the quality and availability of food resources, consumers should adjust their foraging behavior in a manner that maximizes energy and nutrient intake and, when resources are limiting, minimizes dietary overlap with other consumers. Floodplains of the Amazon and its lowland tributaries are characterized by strong,...
Conference Paper
Background/Question/Methods Resource partitioning has been demonstrated in a wide array of communities including invertebrates, vertebrates and plants. Floodplains of the Amazon River are characterized by diverse assemblages of frugivorous fishes including many species that are closely related and morphologically similar. Here we test the null hy...

Full-text available
Fishes probably were the first vertebrate seed dispersers, yet little research has examined this phenomenon. We review evidence of fruit and seed consumption by fishes, and analyze the evolution of frugivory and granivory using South American serrasalmids as a model. Frugivory and granivory are observed among diverse fish taxa worldwide, although m...

Project
This project aims to identify suitable areas for conservation and restoration of Amazonian forestfrugivorous fish interactions and related ecosystem services using an interdisciplinary approach. We will integrate the climatically suitable areas for frugivorous fish species, riparian vegetation, connectivity within the hydrographic network, and the location of current fishing grounds to define conserved and degraded climatic refugia, and infer potential displacement needs for fisher communities. The integration of the four WPs will result in: i) statistical models assessing the influence of landscape-structure change driven by deforestation on frugivorous fish diversity in areas with different degrees of deforestation; ii) a novel land cover model to project scenarios for 2030, 2050, 2070 and 2090, filling a knowledge gap for the Amazon Basin, and a normative Sustainability Optimum Index Scenario (i.e. a future scenario where land-use change is constrained by international agreements in deforestation control and greenhouse gas reductions); iii) a high-resolution map (100m) of the Amazon River basin with priority areas for conservation and restoration of riparian forests; iv) a participatory protocol involving stakeholders for the conservation of the identified refugia areas ensuring a minimum social impact; and v) the translation of the results to form and inform the local communities and global audience about the current and future hazards, which will support mitigation planning, increase auto protection capacity, and improve policies. Thereby, the proposed project addresses several focal points of the present BiodivERsA call, in particular, theme 2: assessing trade-offs and synergies between targets, benefits and policies for conservation and restoration.
