Past shifts in connectivity in riverine environments (for example, sea-level changes) and the
properties of current drainages can act as drivers of genetic structure and demographic …

Aim Patterns of genetic variation within freshwater fish populations may reflect the historical
impact of climate change on either sea‐level or environmental conditions. Past sea‐level …

Aim The disjunct distributions of freshwater organisms along coastal drainages are usually
explained by palaeodrainages formed during sea‐level retreats that connected currently …

Drainage rearrangements, either headwater captures or coastal paleodrainages formed
when sea level was low, are often invoked to explain connectivity and isolation among fish …

Assessments of spatial and temporal congruency across taxa from genetic data provide
insights into the extent to which similar processes structure communities. However, for …

Paleo-drainage connections and headwater stream-captures are two main historical
processes shaping the distribution of strictly freshwater fishes. Recently, bathymetric-based …

The coastal basins of eastern Brazil are influenced by geomorphologic and climatic changes
that caused river captures and temporary paleo‐connections due to sea‐level oscillations …

Obligate freshwater taxa are frequently distributed among catchments isolated by marine
and terrestrial barriers. Such distributions can arise through vicariant changes in drainage …

Freshwater fishes often display a marked phylogeographic structure strongly associated with
historical and ecological changes in the aquatic environment. Different ecological conditions …

Understanding the structure of hybrid zones provides valuable insights about species
boundaries and speciation, such as the evolution of barriers to gene flow and the strength of …
