The Amazon River Basin’s extraordinary social–ecological system is sustained by various water phases, fluxes, and stores that are interconnected across the tropical Andes mountains, Amazon lowlands, and Atlantic Ocean. This “Andes–Amazon–Atlantic” (AAA) pathway is a complex hydroclimatic system linked by the regional water cycle through atmospheric...
The impoundment of the Yangtze River and construction of the Three Gorges Dam and Reservoir created an unnatural flow regime with a 30 m water-level fluctuation and four artificial seasons that differ from the river's natural flow-regime timing. Using stable isotopes, we selected 15 common benthic fish species representing five trophic guilds to an...
The Three Gorges Reservoir is one of the largest reservoirs in the world. Previous studies uncovered longitudinal changes in fish assemblages among riverine, transitional, and lacustrine zones, but whether they vary at small-scale habitats and how tributaries contribute to fish conservation is poorly understood. We selected three neighboring tribut...
To understand the ecological relevance of fish-forest interactions, we sampled fish for a period of 8 months in a lowland forest of the Brazilian Amazon and evaluated the germination of intact seeds recovered from the intestine of three species of congeneric and sympatric freshwater sardines, Triportheus albus, T. angulatus and T. auritus. The numb...
Aim
A primary goal of community ecology is to understand the mechanisms that drive species' spatial distribution and habitat associations. Species' geographic distribution can be influenced by the distribution of their prey partly because consumers' behaviour is oriented to optimal energy use during foraging. We analysed how differences in dietary...
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...
Miller's witch-alder (Fothergilla milleri, Hamamelidaceae) is a newly described globally imperiled shrub that is known from disjunct populations in coastal Alabama, the panhandle of Florida, and one location in Georgia. Little is currently known about the natural history or ecology of the species. We conducted inventories of three populations of F....
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...
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...
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...

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...
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,...
The composition of land use/land cover (LULC) in coastal watersheds has many implications for estuarine system ecological function. Land use/land cover can influence allochthonous inputs and can enhance or degrade the physical characteristics of estuaries, which in turn affects estuaries' ability to support local biota. However, these implications...
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...
Science Panel for the Amazon, Chapter 23. In: Amazon Assessment Report 2021
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...
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...
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 versus mutualistic interactions with seeds.
Here, we evaluated how a reduction in the abundance and species richness of large‐bodied frugivorous fishes affe...
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...
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...
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...
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 environmental...
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...
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...
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....
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...
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...
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...
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...
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 >...
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...
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...
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,...
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...
I investigated changes in abundance and spatial distribution of medium- and large-sized fishes (> 100 mm) in an oxbow lake of the lower Apaporis River, Colombian Amazon, across three seasons (falling, low, and rising water). Fifty-three species in 13 families were collected from six habitats: lagoon channels, stream, flooded forests, isolated shrub...
Matched sets of gillnets of different mesh-sizes were used to evaluate the degree to which contiguous and connected flooded forest and floating meadow habitats are characterized by distinct fish faunas during the flooding season in the Peruvian Amazon. For fishes between 38–740 mm standard length (LS) (the size range captured by the gear), an overr...
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...
Three new species of the Neotropical electric fish Rhabdolichops are described from the lowland Central Amazon Basin of Brazil. These taxa are described using features of color pattern, morphometric and meristic traits, squamation, and osteology. Rhabdolichops nigrimans and R. navalha are known only from low-conductivity blackwater systems whereas...
