Published: July 5, 2022

Abstract Rivers are basic natural resources supporting ecosystems and human societies, the health of rivers is crucial to Earth's sustainable development. Under profound influence climate change activities, great changes have recently occurred in circulation development rivers, as well ways which they utilized. In this context, achieving an effective balance between river protection necessary. paper, essential role discussed from three aspects: formation evolution shaping biodiversity, cultivation civilization. The paper analyzes challenges brought by change, increased water demand, proposes four dimensions future research: scientifically balancing relationship protection, improving adaptability utilization context integrity intelligence level management, building a more fair comprehensive management model.

Geodiversity in the Amazon drainage basin

Philosophical Transactions of the Royal Society A Mathematical Physical and Engineering Sciences, Journal Year: 2024, Volume and Issue: 382(2269)

Published: Feb. 12, 2024

The Amazon is the largest drainage basin on Earth and contains a wide variety of abiotic landscape features. In spite this, geodiversity in this has not yet been objectively evaluated. We address knowledge gap by combining meta-analysis an existing global map its components with systematic literature review, to identify key characteristics (ADB). also evaluate how these component maps, that are based geology, geomorphology, soils hydrology, could be refined better reflect basin. Our review shows geology—through lithological diversity geological structures—and hydrology—through hydrological processes influence geomorphology soil diversity—are main determinants geodiversity. Based features, ADB can subdivided into three principal regions: (i) Andean orogenic belt western Amazon, (ii) cratons eastern (iii) Solimões-Amazon river system. Additional methods geomorphological have identified. Future research should focus investigating relationship between assess their biodiversity. Such enhance conservation plans for ADB.

Drainage and sedimentary response of the Northern Andes and the Pebas system to Miocene strike‐slip tectonics: A source to sink study of the Magdalena Basin

Abstract Miocene strike‐slip tectonics was responsible for creating and closing short‐lived (ca. 6 Ma) passages the emergence of isolated topography in Northern Andes. These geological events likely influenced migration and/or isolation biological populations. To better understand paleogeography hinterland foreland regions Andes, we conducted a source‐to‐sink approach Magdalena Basin.

Neogene History of the Amazonian Flora: A Perspective Based on Geological, Palynological, and Molecular Phylogenetic Data

Annual Review of Earth and Planetary Sciences, Journal Year: 2023, Volume and Issue: 51(1), P. 419 - 446

Published: May 31, 2023

The Amazon hosts one of the largest and richest rainforests in world, but its origins remain debated. Growing evidence suggests that geodiversity geological history played essential roles shaping Amazonian flora. Here we summarize geo-climatic review paleopalynological records time-calibrated phylogenies to evaluate response plants environmental change. Neogene fossil record major sequential changes plant composition an overall decline diversity. Phylogenies eight clades paint a mixed picture, with diversification most groups best explained by constant speciation rates through time, while others indicate clade-specific increases or decreases correlated climatic cooling increasing Andean elevation. Overall, forest seems represent museum diversity high potential for biological time. To fully understand how got modern biodiversity, further multidisciplinary studies conducted within multimillion-year perspective are needed. ▪The rainforest goes back beginning Cenozoic (66 Ma) was driven climate forces.▪In early (23–13.8 Ma), large wetland developed episodic estuarine conditions vegetation ranging from mangroves terra firme forest.▪In late (13.8–2.6 changed into fluvial landscape less diverse more open forest, although details this transition be resolved.▪These have left imprints on can recovered dated phylogenetic trees.▪Amazonian show distinct responses changes, suggesting Amazonia is both refuge cradle biodiversity.

Unravelling genetic structure of the neotropical freshwater crab Sylviocarcinus pictus (Decapoda, Trichodactylidae) along the rapids‐dwelling Xingu River, Amazon basin

Acta Zoologica, Journal Year: 2025, Volume and Issue: unknown

Abstract Sylviocarcinus pictus is a freshwater crab widely distributed across the Amazon basin and coastal basins of northern South America. In Xingu River basin, Pará, Brazil, species found from its middle portion up to confluence with River. This extensive distribution led questions about influence Volta Grande do rapids on genetic diversification between populations above below this area. To explore hypothesis, 39 mitochondrial gene sequences (COI 16S rRNA) 22 samples collected both areas were analysed in phylogeographic context. Bayesian Inference haplotype networks revealed at least two genetically distinct lineages S. The resulting structure within these raised taxonomic cohesion taxon potential existence cryptic that warrant further investigation. best our knowledge, first molecular study basin. Given novelty underestimated diversity region, we advocate for additional studies morphological approaches contribute future understanding evolutionary history genus.
