“…Several historical and contemporary factors may influence the genetic diversity in natural populations. Species’ establishment and/or persistence in a particular region depends on the suitability of that habitat, which is strongly related to historical factors such as climate and geological events and may therefore imprint a signal in the species genetic pool over time (Hewitt, ; Carvalho et al., ).

Premise Despite the efforts to understand the processes that shape neotropical biodiversity, the complexity of certain biomes, such as the Atlantic Forest (AF), prevents the generalization of patterns. Initially, ecological niche modeling (ENM), with phylogeographic studies, identified past stable areas in the central and northern portions of the AF, while the southern portion was thought to be highly fragmented. Here, we examined the phylogeography, historical patterns, genetic diversity, and population structure of Vriesea incurvata, an endemic species of the southern portion of the AF. Methods We evaluated 149 individuals using two plastid DNA regions (cpDNA) and 13 nuclear microsatellite markers (nuSSRs) to access the historical patterns, genetic diversity, and structure of V. incurvata populations. We also conducted historical demography and ENM analyses. Results We found moderate to high genetic diversity and low population structure for both genomes. The cpDNA network revealed high haplotype sharing. The ENM suggested no drastic changes in suitable areas for V. incurvata occurrence, corroborating the finding of no phylogeographic structure. Conclusions Contrary to some studies, our results indicate that the southern AF was a historically stable climate region for V. incurvata occupation after southward colonization by the species. Past climatic changes probably did not cause structuring among its populations.

“…Carvalho et al. (), studying Euterpe edulis Mart., a plant from AF, found that genetic diversity was higher in sites with historically stable climate. Other research noted high genetic diversity in areas considered a refuge for natural populations in the AF during the Quaternary climatic oscillations (Carnaval et al., ; Leite et al., ).…”

“…Additionally, some populations of this palm have low genetic diversity because of the absence of large seed dispersers. In contrast, populations of this species in areas with a stable climatic history have higher genetic diversity (Carvalho et al, 2017).…”

“…CSAs ensure the survival of different species by providing them with suitable habitats over time (Carnaval et al, 2009). CSA, in combination with the presence of large-sized seed dispersers, was important for maintain genetic diversity of Euterpe edulis, a key palm tree within Atlantic Forest biome (Carvalho et al, 2017). Therefore, PAs that cover CSAs offer species long-term protection, regardless of the species' dispersion ability and distribution shifts (Collevatti et al, 2013).…”

The Amazon and Atlantic Forest are considered the world's most biodiverse biomes. Human and climate change impacts are the principal drivers of species loss in both biomes, more severely in the Atlantic Forest. In response to species loss, the main conservation action is the creation of protected areas (PAs). Current knowledge and research on the PA network's conservation efficiency is scarce, and existing studies have mainly considered a past temporal view. In this study, we tested the efficiency of the current PA network to maintain climatically stable areas (CSAs) across the Amazon and Atlantic Forest. To this, we used an ecological niche modeling approach to biome and paleoclimatic simulations. We propose three categories of conservation priority areas for both biomes, considering CSAs, PAs and intact forest remnants. The biomes vary in their respective PA networks' protection efficiency. Regarding protect CSAs, the Amazon PA network is four times more efficient than the Atlantic Forest PA network. New conservation efforts in these two forest biomes require different approaches. We discussed the conservation actions that should be taken in each biome to increase the efficiency of the PA network, considering both the creation and expansion of PAs as well as restoration programs.
