We provide a general compilation of the diversity and geographical distribution Amazonian fishes, updated to end 2018. Our database includes documented distributions 4214 species (both from surrounding basins), compiled published information plus original data ichthyological collections. results show that Amazon basin comprises most diverse regional assemblage freshwater fishes in world, with 2716 valid (1696 which are endemic) representing 529 genera, 60 families, 18 orders. These permit...
Neotropical freshwater fishes (NFFs) constitute the most diverse continental vertebrate fauna on Earth, with more than 6,200 named species compressed into an aquatic footprint <0.5% of total regional land-surface area and representing greatest phenotypic disparity functional diversity any ichthyofauna. Data from fossil record time-calibrated molecular phylogenies indicate that higher taxa (e.g., genera, families) diversified relatively continuously through Cenozoic, across broad...
Abstract The upper rio Paraná basin drains the most developed and environmentally degraded region in South America: Brazilian southeast. While it is one of well-known Neotropical fish assemblages, also threatened by anthropic activity. Urbanization, deforestation, dam construction, invasive species, water pollution not only reduce living area species but alter our perception its biotic elements. Such changes are so profound pervasive that raise uncertainties about native or non-native status...
ABSTRACT Biogeography of Amazonian fishes (2,500 species in vastly disjunct lineages) is complex and has so far been approached only partially. Here, we tackle the problem on basis largest database yet geographical distribution phylogenetic relationships fishes, including all information available. Distributions 4,095 (both outgroups) 84 hypotheses (comprising 549 phylogenetically-informative nodes) were compiled, qualified plotted onto 46 areas (29 17 non-Amazonian). The was analyzed with...
A new species of Moenkhausia is described from the upper rio Tocantins basin, States Goiás and Tocantins, Brazil. goya, species, can be distinguished its congeners by shape humeral blotch in combination with a uniform dark pigmentation covering interradial membranes dorsal anal fins. Among congeners, most similar to M. britskii Azevedo-Santos & Benine, grandisquamis (Müller Troschel) xinguensis Steindachner presenting deep body, large, round fins without discrete patches (i.e.,...
Abstract The Brazilian Cerrado, one of the most threatened biomes our planet, illustrates challenges and opportunities reconciling economic development with conservation land water ecosystems. Here, we assess state art present new information on impacts agricultural expansion, dams, use, make recommendations for basin management, conservation, restoration water‐related Cerrado ecosystems rivers. requires not only preservation remnants its vegetation but also ability to keep...
A new species of Hyphessobrycon Durbin is described from tributaries the rio Grande (rio São Francisco basin) draining east to Serra Geral de Goiás, Domingos (upper Tocantins and do Sono basins (middle basin). Hyphessobrycondiastatos can be diagnosed its congeners by absence humeral spot, 15-18 branched anal-fin rays, 1-3 maxillary conical tricuspid teeth, a relatively well-defined dark caudal-peduncle elongation dorsal- rays in mature males. The biogeographical significance distribution...
A new species of Hemigrammus is described from the middle rio Tocantins basin, central Brazil. The can be distinguished all congeners by having a black midlateral stripe on body extending posterior margin eye to median caudal-fin rays. Mature males possess dorsal-, pelvic-, and anal-fin rays elongate, features that also help recognize species. Although in Hemigrammus, some specimens present complete series pored scales lateral line. discussion about generic allocation presented.
Moenkhausia rubra, new species, is described from the upper rio Juruena, Tapajós basin, Mato Grosso, Brazil. The species distinguished its congeners, except M. hemigrammoidesand nigromarginata, by dark pigmentation on anteriormost rays of both dorsal and anal fins. rubrais aforementioned number branched anal-fin 17-20 (vs. 20-25), presence a blotch caudal peduncle extending to middle caudal-fin rays, absence longitudinal black zigzag stripes between rows scales body, other details coloration.
Abstract Freshwater ecosystems represent less than 0.01% of Earth's surface water but proportionately encompass the most species‐rich environment on planet, including nearly one‐third all vertebrate species. Even though inland continental waters are widely regarded as highly endangered ecosystems, their species assemblages mostly ignored in conservation plans, largely because spatial patterns freshwater remain poorly understood. This is particularly severe throughout Neotropics, notably...
Abstract The diet of indicator fish species plays a crucial role in assessing ecosystem health. This study evaluated streams with and without urban influences, focusing on abiotic parameters the trophic ecology Psalidodon fasciatus Piabina argentea . Forested exhibited higher redox potential, dissolved oxygen, transparency, depth, whereas had temperatures, greater widths, increased levels total solids, conductivity, coliforms, thermotolerant coliforms. P. population isometric growth forested...
Abstract Conservation policies in Brazil differ between the “biomes” into which country has divided its territory since 2004. The Amazon biome is predominantly tropical forest but also includes unique savanna ecosystems, while Cerrado composed of various types islands and corridors forest. Confusion, both inadvertent deliberate, terms “savanna” resulted reducing protection Amazonian savannas by allowing less-demanding requirements applicable to be applied. Threats are increased legal...
ABSTRACT The history of knowledge about Amazonian biogeography is as rich its fish community, and a fascinating theme study in itself. Several current paradigms controversies are rooted principles dating from the second half 18th to first 19th centuries. present work establishes relationship between biogeographical ideas their old predecessors, on basis chronologically-oriented historical continuity analysis. advent evolutionary theory has not contributed significantly transformation fishes....
Abstract The IUCN Red List (RL) provides high-quality conservation assessments for individual species, yet the rate and scale of environmental deterioration globally challenges community to develop expedited methods risk assessment. Here we compare threat 3,001 species Neotropical freshwater fishes (NFF) in IUCN–RL using readily accessible data types as proxies extinction risk: geographic range, elevation, publication date. Furthermore, taxonomic alone, generated preliminary 2,334 NFF...
A new species of Hyphessobrycon is described from the Rio Papagaio, a tributary Juruena, Tapajós basin, Brazil. The taxon can be distinguished its congeners by having well-defined and relatively narrow dark midlateral stripe on body extending upper half posterior margin eye to middle caudal-fin rays, absence humeral blotch, 16–19 branched anal-fin 2–4 maxillary teeth, six pelvic-fin pigmentation crossing eye. cyanotaenia, few specimens aquarium trade without precise locality, redescribed...
Abstract The Neotropics harbors a megadiverse ichthyofauna comprising over 6300 species with approximately 80% in just three taxonomic orders within the clade Characiphysi. This highly diverse group has evolved tropical South America tens to hundreds of millions years influenced mostly by re‐arrangements river drainages lowland and upland systems. In this study, we investigate patterns spatial diversification Neotropical freshwater fishes family Curimatidae, species‐rich order Characiformes....
Abstract A new species of Moenkhausia is described from the rio Machado drainage, Amazon basin, Brazil. It diagnosed congeners by its color pattern, consisting concentration chromatophores on anterior portion body scales, horizontally elongate blotch caudal peduncle, a bright golden coloration dorsal eye when alive, and dark line crossing horizontally. The has variable morphology regarding trunk lateral-line canals. Most fully grown individuals do not have enclosed bony tube in many lateral...
Abstract The Serra do Cachimbo is a highland area at the southeastern portion of Amazon Forest drained by headwaters tributaries rios Xingu and Tapajós. It known as an high level endemism fish, low species diversity, very few taxa with broad distribution in other parts Amazon. Despite its biogeographical importance, there are still many poorly sampled areas. Four expeditions to region yielded rediscovery known, endemic species, Hyphessobrycon cachimbensis, discovery similar, allopatric...
Abstract The Tocantins-Araguaia River basin hosts an elevated number of fish species, and new species have been continuously described. In this basin, we investigated patterns endemic descriptions examining their association with distribution range, altitudinal gradient, fluvial hierarchy watercourses, sampling effort. For each collected its year taxonomic description, geographical coordinates holotype, body size (a proxy for range), both altitude effort related to the locality holotype. was...
