“…The growing number of publications with native palms from AF followed a global trend of exponential growth in the number of scientific publications over recent decades (Nabout et al, 2012; Pereira et al, 2018; Tinoco et al, 2015). Scientometric analyses have also shown a significant increase in scientific production of native palms in the state of Santa Catarina, Brazil (Elias et al, 2015).…”

Palms (Arecaceae) exert great relevance to the structure and functioning of tropical forest ecosystems, in addition to comprise key resources for frugivorous animals. However, many species are currently at risk of extinction due to overexploitation and/or habitat loss. Our study aimed to perform a systematic review with a scientometric approach of all 78 native palm species of the Brazilian Atlantic Forest, seeking to identify the best‐studied species and regions, main studied topics, overall patterns, trends and gaps in scientific research associated with this botany family. In total, studies were carried out for 48 species belonging to 10 genera, with the number of studies exponentially increasing from the 70s and exhibiting great difference in the number of publications among species. Euterpe edulis was the most studied species (n = 274), followed by Acrocomia aculeata (n = 205), whereas Bactris bahiensis (1), Geonoma litoralis (1), Syagrus santosii (1) and Trithrinax acanthocoma (0) comprised the less studied species. The largest number of studies was carried out in the south‐eastern states of Brazil. Regarding the type of studies, 34% and 27% were related to biochemical properties and ecological processes, respectively, while studies on entomology (n = 26), tissue culture (n = 23) and taxonomy (n = 7) showed the lowest number of studies. Given the key role of palms in tropical forests, our study suggests that future research should focus on less studied species, including Desmoncus spp., Geonoma spp. and Trithrinax sp., and on some less studied areas like the north‐east portion of the Atlantic Forest.

ResumoAs palmeiras (Arecaceae) exercem grande relevância na estrutura e funcionamento dos ecossistemas de florestas tropicais, além de compreenderem recursos‐chave para animais frugívoros. Entretanto, muitas espécies estão atualmente em risco de extinção devido à superexploração e/ou perda de habitat. Nosso estudo visou realizar uma revisão sistemática com uma abordagem cientométrica de todas as 78 espécies de palmeiras nativas da Mata Atlântica brasileira, buscando identificar as espécies e regiões mais bem estudadas, principais tópicos estudados, padrões gerais, tendências e lacunas na pesquisa científica associada a esta família botânica. No total, foram realizados estudos para 48 espécies pertencentes a 10 gêneros, com o número de estudos aumentando exponencialmente a partir dos anos 70 e exibindo grande diferença no número de publicações entre as espécies. Euterpe edulis foi a espécie mais estudada (n = 274), seguida por Acrocomia aculeata (n = 205), enquanto Bactris bahiensis (1), Geonoma litoralis (1), Syagrus santosii (1) e Trithrinax acanthocoma (0) foram as espécies menos estudadas. O maior número de estudos foi realizado nos estados do sudeste do Brasil. Com relação ao tipo de estudos, 34% e 27% estavam relacionados a propriedades bioquímicas e processos ecológicos, respectivamente, enquanto os estudos sobre entomologia (n = 26), cultura de tecidos (n = 23) e taxonomia (n = 7) representaram o menor número. Dado o papel fundamental das palmeiras nas florestas tropicais, nosso estudo sugere que as pesquisas futuras devem se concentrar em espécies menos estudadas, incluindo Desmoncus spp., Geonoma spp. e Trithrinax sp. e em algumas áreas menos estudadas, como a porção nordeste da Mata Atlântica.

“…Given the potential for millions of years of separation between Amazonian and Central American populations, some widespread taxa may represent independently evolving lineages yet to be described as separate species (Damasco et al., 2021), but in other cases widespread species could still represent a single gene pool (Brito et al., 2023). As Neotropical rain forest trees have been genetically understudied relative to their temperate counterparts (Tinoco et al., 2015), it remains an open question whether dispersal between biogeographic regions has left predictable signatures in genetic structure of contemporary populations, and whether the impact of dispersal on genetic structure has been affected by species‐specific traits.…”

The Andes are a major dispersal barrier for lowland rain forest plants and animals, yet hundreds of lowland tree species are distributed on both sides of the northern Andes, raising questions about how the Andes influenced their biogeographic histories and population genetic structure. To explore these questions, we generated standardized datasets of thousands of SNPs from paired populations of 49 tree species co‐distributed in rain forest tree communities located in Panama and Amazonian Ecuador and calculated genetic diversity (π) and absolute genetic divergence (dXY) within and between populations, respectively. We predicted (1) higher genetic diversity in the ancestral source region (east or west of the Andes) for each taxon and (2) correlation of genetic statistics with species attributes, including elevational range and life‐history strategy. We found that genetic diversity was higher in putative ancestral source regions, possibly reflecting founder events during colonization. We found little support for a relationship between genetic divergence and species attributes except that species with higher elevational range limits exhibited higher dXY, implying older divergence times. One possible explanation for this pattern is that dispersal through mountain passes declined in importance relative to dispersal via alternative lowland routes as the Andes experienced uplift. We found no difference in mean genetic diversity between populations in Central America and the Amazon. Overall, our results suggest that dispersal across the Andes has left enduring signatures in the genetic structure of widespread rain forest trees. We outline additional hypotheses to be tested with species‐specific case studies.
