Drainage rearrangements and in situ diversification of an endemic freshwater fish genus from north‐eastern Brazilian rivers

Abstract: 1. Drainage rearrangements, either headwater captures or coastal paleodrainages formed when sea level was low, are often invoked to explain connectivity and isolation among fish populations. Unravelling these events is crucial for understanding the evolutionary processes that have shaped the genetic diversity and

“…And then, the isolation role of the Nanling Mountains could result in genetic divergence between the infra-sublineage A-IIb living in the Gan River of the Yangtze River drainage and A-IIc inhabiting the Pearl and Han rivers. Stream capture across drainage divides has also been widely invoked to explain range expansion of freshwater fishes through vicariance processes (Burridge et al, 2006;Yang et al, 2009;Xu et al, 2014;Kim et al, 2017;Lima et al, 2017;Souza et al, 2020;Lima et al, 2021;Barreto et al, 2022). The close genetic relationships between the Pearl River and Han River in S. parvus has also been observed in another freshwater gudgeon, Squalidus argentatus (Yang et al, 2012).…”

“…Phylogeographic research on freshwater fish has continued to play an important role in understanding the underlying causal factors shaping inter-and intra-specific genetic variations of freshwater fish biodiversity across contemporary isolated drainages (Shelley et al, 2020;Van Steenberge et al, 2020;Waters et al, 2020;Lima et al, 2021;Yang et al, 2022). Landscape evolution, either through tectonic activities or drainage rearrangements, has been considered to be a major driver for the diversification of obligate freshwater fishes (Burridge, et al, 2006;Unmack et al, 2013;Swartz et al, 2014;Xu et al, 2014;Zúñiga-Vega et al, 2014;Craw et al, 2016;Lima et al, 2017;Souza et al, 2020;Sholihah et al, 2021;Barreto et al, 2022;Souto-Santos et al, 2022;Val et al, 2022). One type of drainage rearrangement is stream capture, a geomorphological process that refers to a stream displacing a portion of another neighboring stream due to tectonic or erosive events (Bishop, 1995).…”

“…Freshwater fish in contemporary isolated drainages are often the products of historical river evolutions. Therefore, phylogeographical studies of freshwater fish are significant for understanding the historical reorganization or rearrangements of rivers within and among drainages [ 3 , 4 , 5 , 6 ]. The genetic diversity observed within a species is a key facet of biodiversity that reflects the evolutionary history and adaptability of a species as a whole, or its constituent populations [ 7 , 8 ].…”

“…The influence of coastal paleodrainages on the diversification of freshwater fishes took place mainly in the Quaternary, particularly the Pleistocene, when sea level fluctuations reshaped the connections between previously isolated rivers (Baroni et al, 2021; Thomaz & Knowles, 2020; Thomaz & Knowles, 2018). Although the importance of these processes is evident, it is still not clear how exactly both influenced the history of ichthyofauna diversification in northeastern Brazilian coastal basins (Barreto et al, 2022).…”
