“…Global temperature increasing events are indicated during the Holocene (11.300 years until present) in tropical zones (Marcott et al, 2013), and their effects can cause significantly important oscillations in the demography and in the population genetics of many species including tiger sharks as observed herein. These signs of Ne oscillations over time have been demonstrated at several different species (Torres & Ribeiro, 2009;Von der Heyden et al, 2011;der Heyden et al, 2013;Teske et al, 2013;Lima et al, 2016;Baggio et al, 2017;Machado et al, 2017). Despite the occasional capability on reaching temperatures below 15°C, tiger sharks seem to prefer warmer waters.…”

“…This result corroborates the river-capture event suggested by Maia et al (2013) based on the occurrence of P. garbei in a single tributary adjacent to the headwaters of Macaé river basin. These drainage rearrangements are the result of tectonic reactivation that started in the Paleogene and continues to the present ( Ribeiro et al, 2006 ; Lima and Ribeiro, 2011 ; Lima et al, 2016 ).…”

Paleo-drainage connections and headwater stream-captures are two main historical processes shaping the distribution of strictly freshwater fishes. Recently, bathymetric-based methods of paleo-drainage reconstruction have opened new possibilities to investigate how these processes have shaped the genetic structure of freshwater organisms. In this context, the present study used paleo-drainage reconstructions and single-locus cluster delimitation analyses to examine genetic structure on the whole distribution of Pareiorhaphis garbei, a ‘near threatened’ armored catfish from the Fluminense freshwater ecoregion in Southeastern Brazil. Sequences of two mitochondrial genes (cytochrome b and cytochrome c oxidase subunit 1) were obtained from five sampling sites in four coastal drainages: Macaé (KAE), São João (SJO), Guapi-Macacu [sub-basins Guapiaçu (GAC) and Guapimirim (GMI)], and Santo Aleixo (SAL). Pronounced genetic structure was found, involving 10 haplotypes for cytB and 6 for coi, with no haplotypes shared between localities. Coalescent-based delineation methods as well as distance-based methods revealed genetic clusters corresponding to each sample site. Paleo-drainage reconstructions showed two putative paleo-rivers: an eastern one connecting KAE and SJO; and a western one merging in the Guanabara Bay (GAC, GMI, and SAL). A disagreement was uncovered between the inferred past riverine connections and current population genetic structure. Although KAE and SJO belong to the same paleo-river, the latter is more closely related to specimens from the Guanabara paleo-river. This discordance between paleo-drainage connections and phylogenetic structure may indicate an ancient stream-capture event in headwaters of this region. Furthermore, all analyses showed high divergence between KAE and the other lineages, suggesting at least one cryptic species in the latter, and that the nominal species should be restricted to the Macaé river basin, its type locality. In this drainage, impacts such as the invasive species and habitat loss can be especially threatening for such species with a narrow range. Our results also suggest that freshwater fishes from headwaters in the Serra do Mar mountains might have different biogeographical patterns than those from the lowlands, indicating a complex and dynamic climatic and geomorphological history.

“…Genetic structure among isolated coastal basins was also observed in other rheophilic freshwater catfishes from the Serra do Mar streams (Lima et al, 2016;Zamudio et al, 2009), and along the coastal Andean basins (Unmack et al, 2009(Unmack et al, , 2012. Species found in high-and lowland streams may move between river basins (Unmack et al, 2012) by river capture events or palaeodrainages dispersal.…”

Aim:The disjunct distributions of freshwater organisms along coastal drainages are usually explained by palaeodrainages formed during sea-level retreats that connected currently isolated basins, or by river capture from tectonic adjustments between adjoining watersheds. We evaluate the relative importance of these events on the genetic variation of freshwater fishes inhabiting the Serra do Mar in eastern Brazil, a region with steep mountains and pronounced bays.Location: Coastal river drainages in southeastern Brazil.Taxon: Catfishes of the Trichomycterus alternatus group. Methods:We tested the effects of palaeolandscape connections (GIS-reconstructed palaeodrainages and putative river captures) on the genetic structure (mitochondrial and nuclear markers) of T. alternatus from 15 drainages using phylogenetic reconstructions, lineage delimitation methods and analyses of molecular variance. Results:Trichomycterus alternatus is monophyletic and comprised of three main lineages: two restricted to the basin at its northernmost distribution and another broadly distributed to the south. In the latter, seven major cytb clades were geographically compatible with the eight palaeodrainages, with three incongruences matching river captures previously described for the Guanabara Bay (GB). Shared haplotypes among isolated rivers flowing into GB provide the first molecular evidence of the 'Rio de Janeiro' palaeoriver.Main conclusions: Dispersal via palaeorivers is an important process, but it is not enough to recover the most recent dispersive events. Therefore, integrating both
