“…Regions with many gene trees which agree on topology and/or branch lengths are colored in blue, and the consensus tree is represented by a dark blue line. Divergence times and 95% HPD intervals for each node (a and b) can be found in (Carnaval, 2002;Carnaval & Bates, 2007 (Silveira et al, 2019). Our results support the hypotheses of Silveira et al (2019) populations (e.g., Amaral et al, 2013;Batalha-Filho, Maldonado-Coelho, & Miyaki, 2019;Brunes et al, 2014;Cabanne et al, 2008Cabanne et al, , 2013Maldonado-Coelho, 2012).…”

“…Split events in D. oliveirai exhibit spatial and temporal concordance with other Pleistocene divergences in the Atlantic Forest(Batalha-Filho et al, 2014;Cabanne et al, 2008;Menezes et al, 2016;Thomé et al, 2010). Finally, our results support the isolation and reconnection dynamics between enclaves and coastal forests in Pleistocene during forests expansions in the LGM, as inferred for Atlantic Forest trees through niche modeling(Silveira et al, 2019).Amphibians from Atlantic Forest enclaves have been shown to be genetically closely related to lowland coastal Atlantic Forest populations, hence supporting the hypothesis of recent establishment of these enclaves during the Pleistocene (Carnaval, 2002; Carnaval & Bates, 2007; Silveira et al, 2019). Our results show not only low genetic differentiation, but also connection among some enclaves and lowland areas with ongoing gene flow.…”

Cyclical climatic changes during the Pleistocene produced glacial and interglacial periods that shaped spatial distribution and genetic composition of populations at high latitudes across the world (Alexandrino, Arntzen, & Ferrand, 2002; Milot, Gibbs, & Hobson, 2000). The importance of climatic fluctuations is easily acknowledged for temperate regions, where huge glaciers have contracted and expanded, repeatedly obliterating many species from most of their ranges. The role played by glaciations in tropical regions, such as those in South

“…Floristic enclaves have been frequently found in many vegetation maps world-wide, whether based on physiognomy or species composition (e.g. Cantidio & Souza, 2019;Castro-Insua et al, 2018;Jeske-Pieruschka & Behling, 2012;Linder et al, 2012;Silva & Souza, 2018a;Silveira, Mascarenhas, Cardoso, & Batalha-Filho, 2019;Veloso et al, 1991). The existence of enclaves is commonly attributed to the existence of island-like environmental conditions like mountain tops with climates colder than those prevailing in the surrounding subregions (Cantidio & Souza, 2019;Silva & Souza, 2018a or historical biogeographical processes like assemblages that are relicts of communities with wider distribution in the past (Cantidio & Souza, 2019;Daru, Elliott, Park, & Davies, 2017;Jeske-Pieruschka & Behling, 2012).…”

1. The Amazon forest covers 7.5 million km 2 in nine countries, hosts 25% of the global biodiversity and is a major contributor to the biogeochemical and climatic functioning of the Earth system. Despite its global importance, a regionalization of the Amazon tree flora is still lacking. Clear and data-driven delimitation of subregions is important for macroecological studies, to the identification of metacommunities and is a requisite for conservation planning. 2. We aimed at identifying and mapping plant species subregions and investigated their relationships with environmental, historical and human correlates. We provide the first woody plant regionalization of the entire Amazon forest using a datadriven approach based on assemblage composition patterns. 3. We compiled data on woody species composition from 301 assemblages based on species occurrences. We then used unconstrained ordination, interpolation and clustering techniques to identify and map discrete woody subregions. Hierarchical clustering analysis was conducted in order to investigate the relationships between the identified subregions. We used multinomial logistic regression model and deviance partitioning to investigate the influence of environmental, historical and human factors on subregions distribution. 4. We identified 13 woody subregions in the entire Amazon forest. The hierarchical subregion classification showed a broad Andean-Cratonic east-west division. Variation in subregions was explained jointly by human factors and spatial structure followed by environmental factors and spatial structure combined. 5. Synthesis. Our woody plant subregions differed from World Wildlife Fund ecoregions and physiognomic-based maps, highlighting the importance of basing regionalizations on taxon-specific groups and confirming that vegetation maps should not be used as proxies to plant diversity subregions. Our findings also confirm the need for multiple and extensive protected areas in the Amazon forest. The relevance of current climate factors in our study alerts to a profound impact that climate change could have on the spatial organization of the Amazon flora.

Demographic changes during the late Pleistocene-Holocene left signatures in the DNA of contemporary populations. These signatures reveal demographic phenomena like the increase or decrease in effective population size. In this paper we searched for signatures of demographic change in the DNA of the Neotropical freshwater fish Poecilia vivipara. Also, we investigated whether demographic changes are correlated with palaeoclimatic events of the late Pleistocene-Holocene, in particular, if changes in effective population size are correlated with expansion and contraction of available habitats, induced by global ice-volume changes and sea-level fluctuations. We used Bayesian Skyline Plot (BSP) analysis with sequences from the mitochondrial gene cytochrome b to estimate the ancestral demography of the Neotropical freshwater fish P. vivipara. To test the assumptions of neutrality and absence of population structure we used Tajima's D and Spatial Analysis of Molecular Variance (SAMOVA), respectively. Effective population size of P. vivipara remained stable until 75,000 years ago, increased by 10-fold reaching a maximum at approximately 25,000 years ago, then suddenly declined at the Pleistocene-Holocene boundary. Variation in effective population size in P. vivipara correlates with expansion and contraction of habitats induced by sea-level fluctuations, caused by the advance and retreat of ice sheets during the Last
