Basin-scale planning is needed to minimize impacts in mega-diverse rivers
Abstract Is there only one electric eel species? For two and a half centuries since its description by Linnaeus, Electrophorus electricus has captivated humankind capacity to generate strong discharges. Despite the importance of in multiple fields science, possibility additional species-level diversity genus, which could also reveal hidden variety substances bioelectrogenic functions, hitherto not been explored. Here, based on overwhelming patterns genetic, morphological, ecological data, we...
Abstract The Amazon Basin is an unquestionable biodiversity hotspot, containing the highest freshwater on earth and facing off a recent increase in anthropogenic threats. current knowledge spatial distribution of fish species greatly deficient this basin, preventing comprehensive understanding hyper-diverse ecosystem as whole. Filling gap was priority transnational collaborative project, i.e . AmazonFish project - https://www.amazon-fish.com/ Relying outputs we provide most complete records...
Despite growing interest in trait-based approaches to community assembly, little attention has been given seasonal variation trait distribution patterns. Mobile animals can rapidly mediate influences of environmental factors and species interactions through dispersal, suggesting that the relative importance different assembly mechanisms vary over short time scales. This study analyzes changes functional distributions tropical fishes Xingu River, a major tributary Amazon with large...
Length–weight (LWR) and length–length relationships (LLR) are presented for 135 freshwater fish species sampled by several types of fishing gear between April 2012 July 2014 in the middle lower Xingu River Basin, northern Brazil. The report represents first references on LWRs LLRs 114 119 species, respectively, also provides a new maximum size 96 species.
Abstract. The Xingu River is a large clearwater river in eastern Amazonia and its downstream sector, known as the Volta Grande do ("Xingu Great Bend"), unique fluvial landscape that plays an important role biodiversity, biogeochemistry prehistoric historic peopling of Amazonia. sedimentary dynamics sector will be shifted next few years due to construction dams associated with Belo Monte hydropower project. Impacts on biodiversity carbon cycling are anticipated, especially likely changes...
Hepatozoon spp. are apicomplexan parasites that infect a wide variety of animals. The infection occurs through the ingestion hematophagous arthropod definitive host. Herein, we assessed presence in 165 captive wild felids and 100 canids using molecular techniques. We found 6 (4 little spotted cats, 1 jaguarondi, puma) 5 (2 bush dogs, fox, crab-eating maned wolf) were positive for may be potential pathogen an opportunistic parasite immunocompromised animals or if occurring concomitant...
Abstract Hypancistrus was proposed as a monotypic genus for highly unique species, H. zebra, known only from short stretch of the Middle rio Xingu on Brazilian Shield. Subsequent studies added eight all described river systems draining Guiana Analysis specimens middle and lower detected two new species that can be separated its congeners based color pattern body size adults, are well ornamental fish trade. Due to their non-overlapping distributions, prospects conserving quite different. One...
Abstract Rapid habitats are characterized by an environment of intense hydrologic dynamic, hosting freshwater biodiversity that has adapted to these conditions. Knowledge the diversity rapids-dwelling fish is still unsatisfactory in South America’s rivers. Our study surveyed species within rapids from Tocantins-Araguaia River Basin (TARB). We assessed 27 stretches different localities along TARB, using various fishing gears with free diving, preferably deeper areas rocky stretches. survey...
The Neotropical region harbors unique biodiversity and a vast wealth of fish species. Inventories river basins are essential for assessing environmental impacts. In this study, we analyzed the use diving visual census data as complementary tools inventorying rheophilic ichthyofauna in Tocantins River. Compared with traditional methods, censuses register exclusive shared species, increasing efficiency detecting diversity rapids. We observed that Characiformes were predominantly sampled using...
