Hydropower development in the Andean Amazon has been underestimated and will disrupt connected human natural systems.
Atypical fish diversity gradients suggest a recent formation of the Amazon system such as we know it today.
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...
Abstract Upstream range shifts of freshwater fishes have been documented in recent years due to ongoing climate change. River fragmentation by dams, presenting physical barriers, can limit the climatically induced spatial redistribution fishes. Andean ecosystems Neotropical region are expected be highly affected these future disturbances. However, proper evaluations still missing. Combining species distribution models and functional traits Amazon fishes, coupled with dam locations climatic...
Summary Knowledge of fish migration is a prerequisite to sustainable fisheries management and preservation, especially in large international river basins. In particular, understanding whether migratory lifestyle compulsory or facultative, adults home their natal geographic area paramount fully appraise disruptions longitudinal connectivity resulting from damming. the Amazon, catfishes Brachyplatystoma genus are apex predators considerable interest for fisheries. They believed use entire...
With around 15% of all described freshwater fish species in the world, Amazon Basin is by far most species-rich ecosystem on planet. In this opinion paper, a rough evaluation given just how vulnerable Amazonian fishes are to ongoing climate change. And argue that current anthropogenic threats through rapid expansion human infrastructure and economic activities basin could be greater threat communities than those anticipated any future Conservation actions should focus preferentially reducing...
The Madeira River, which drains one of the major tributary river basins upper Amazon, contributes to small-scale fisheries in Peru, Bolivia, and Brazil. This paper provides a base-line resources their status six sub-basins River: Madre de Dios River basin (Peru), Beni Mamoré (Bolivia), Iténez or Guaporé (Bolivia Brazil), middle Madeira, (two sections the) lower (Brazil). Data were collected between 2009 2011, before completion two hydroelectric dams Brazilian portion basin. Biophysical,...
Identifying the main taxonomic, phylogenetic and trait dimensions of beta diversity, evaluating their prospective drivers, advances our understanding patterns processes involved in evolution biological assemblages. Using comprehensive databases on distribution, phylogeny, morphological traits (later referred as functional traits) Amazonian freshwater fishes, we analyzed diversity these three to evaluate historical contemporary drivers. We mostly focused pure turnover components (Taxoβsim,...
Abstract The species of Trichomycterus (Siluriformes: Trichomycteridae) are small catfish distributed throughout South and Central America, from Patagonia to Costa Rica, at elevations ranging sea level over 4,000 m. In Bolivia, 17 have been recorded, but information about the status their populations relationship with environment is unknown. This study addressed population dynamics two (T. cf. corduvensis T. tiraquae) in an Andean river Cochabamba Department a hydrological cycle. Monthly...
Abstract Assessing the effectiveness of protected areas for sustaining species and identifying priority sites their conservation is vital decision making, particularly freshwater fishes in South America, global centre fish diversity. Several planning studies have used threatened or that are vulnerable to climate change as targets, but none has included both priority‐setting analysis. The objectives this study were identify gaps coverage existing representing endemic Tropical Andes region,...
The Andes mountains extend North-South in a latitudinal gradient of 8,500 km. Due to the great climatic variety and peculiar north-south orographic distribution, lakes are very diverse, including different lake origins contrasting morphometries. Here, we reviewed more than 700 ecological studies on Andean identify main threats these freshwater systems. most important UV radiation, changes water balance, eutrophication, all three interacting with climate change, alien species introduction,...
Tropical rainforests harbor extraordinary biodiversity. The Amazon basin is thought to hold 30% of all river fish species in the world. Information about ecology, reproduction, and recruitment most still lacking, thus hampering fisheries management successful conservation strategies. One key understudied issues study population dynamics recruitment. Fish larval ecology tropical biomes its infancy owing identification difficulties. Molecular techniques are very promising tools for larvae at...
ABSTRACT The goliath catfish Brachyplatystoma rousseauxii has crucial economical and ecological functions in the Amazon basin. Although its life history characteristics have been studied Amazon, there is little information Madeira River basin, which holds genetically distinct populations where dams were recently built. Using fish collected Bolivia, Brazil Peru, this study provides a validation of growth rings deposition details patterns B. before dams’ construction. Age structure parameters...
The giant osteoglossomorph fish Arapaima cf. gigas was introduced to the northern Bolivian Amazon over a half century ago and now contributes significantly commercial fisheries. Despite this, little is known regarding its current distribution invasion potential. Here, we address this knowledge gap using two complementary methods: interviewing key informants examining fisheries landing records in principal site (Riberalta). Both interviews data revealed that species represents approximately...
Amazonian ichthyofauna has one of the richest specific diversities on earth. However, life history strategies most species remain poorly-known owing to logistical difficulties, although this information is essential for conservation and sustainable fisheries management. An inventory diversity in plankton samples might be an efficient way studying breeding seasons localities fish species, providing their precise taxonomic identification can ensured. Herein, using barcoding cytochrome c...
Myrciaria dubia (Kunth) McVaugh (camu‐camu) is a shrub native to the Amazon region that produces fruits with high content of vitamin C and various bioactive compounds, making it functional food antioxidant, anti‐inflammatory, antimicrobial properties. However, unknown which microorganisms are associated its root system can influence growth productivity. Arbuscular mycorrhizal fungi (AMF) most plants essential for their establishment, survival, productivity since they facilitate nutrition,...
Species introduction, combined with changing access rules, increasing demand, and new road dam infrastructure, are contributing to remarkable changes in Bolivian Amazon fisheries. This paper examines community responses the appearance of a commercially valuable introduced fish species, Arapaima cf. gigas ("paiche") Amazon. Until end 20th century, fisheries this region were relatively low intensity, focused rivers on small number native large-sized species by an urban-based commercial fishing...
Developing institutional arrangements for supporting sustainable fisheries has been a critical challenge the governance of common-pool resources, especially in transboundary regions. In this paper, we analyze impact on small-scale fishery system Brazil-Bolivia border Amazon region. Data collection involved documental analysis, literature review and conduction semi-structured interviews with fishers environmental protection/regulatory agencies' staff. We present an exploratory qualitative...
