“…The diversity of Hymenaea L. is typically centered in the tropical rainforest, except for H. verrucosa, which is distributed in Sub-Saharan Africa (Mackinder 2005, Fougère-Danezan et al 2007, Bruneau et al 2008, LPWG 2017. Hymenaea comprises 20 recognized species, occurring in several biomes, like tropical rainforests, seasonally dry tropical forests and woodlands (SDTFW), and savannas (Mackinder 2005, Fougère-Danezan et al 2007, Bruneau et al 2008, Souza et al 2014, Lima & Pinto 2015, Ribeiro et al 2015, LPWG 2017, Aguilar et al 2018). In the first revision of the genus, Hymenaea was traditionally divided into two sections based on morphological criteria: (i) sect.…”

Floral traits associated with functional groups of pollinators have been largely employed to understand mechanisms of fl oral diversifi cation. Hymenaea is a monophyletic legume genus widely recognized to being bat-pollinated, with nocturnal anthesis and copious nectar. The most of species has short-paniculate infl orescences, white and robust fl owers, congruent with a bat-pollination syndrome.However, other Hymenaea species show a different fl oral pattern (e.g., long-paniculate infl orescences and smaller fl owers) which we report here as being bird pollinated. We examined the fl oral traits and visitors of Hymenaea oblongifolia var. latifolia and identifi ed evolutionary shifts in fl oral traits associated with potential pollinators of Hymenaea species. Floral traits of H. oblongifolia var. latifolia differ from those expected for bat-pollinated fl owers in species of sect. Hymenaea, and we observed hummingbirds collecting nectar legitimately. Our phylogenetic analysis did not support the monophyly of the taxonomic sections and suggests that bat pollination is ancestral in Hymenaea, with bird pollination evolving later. The transition coupling with shifts in the timing of anthesis and other fl oral traits. Pollinator-mediated evolutionary divergence hypothesis partially explains the Hymenaea diversifi cation in the Neotropics. It is congruent with those species shifting from traits linked traditionally to bat pollination to hummingbird pollination.

“…The former is endemic to the Cerrado biome, and the latter is frequently found in the Atlantic forest and in riverine forests and forest patches within the Cerrado. Despite the lack of phylogenetic studies including all 17 species belonging to this genus (Lee and Langenheim 1975;Ribeiro et al 2015), Fougère-Danezan et al (2007) analyzed cpDNA of six species and observed that H. courbaril, H. eriogyne, and H. stigonocarpa are part of a monophyletic, closely related, and unresolved clade within the genus. In addition, an early review of the genus suggested that savanna species like H. stigonocarpa might have derived from forest Hymenaea lineages (Lee and Langenheim 1975).…”

Studying the genetic structure of vicariant species (i.e., closely related species that occupy ecologically distinct yet adjacent habitats) can shed light on the evolution and divergence of species with different ecological requirements. A previous phylogeographic study identified chloroplast DNA haplotype sharing between two vicariant tree species, one from forest (Hymenaea courbaril) and one from savanna (H. stigonocarpa) habitats. These species co-occur in the Brazilian Cerrado, a biome that encompasses forest patches and riverine forests within a savanna matrix. In order to investigate the evolutionary processes involved in the genetic divergence of these trees, we used nuclear microsatellite markers, statistical methods including approximate Bayesian computation (ABC), and leaf morphology to analyze neighboring and distant populations. Bayesian analysis revealed admixture between the species. ABC analysis supported the scenarios with the occurrence of gene flow between species during the Last Glacial Maximum or from the Holocene to the present, when compared to alternative scenarios of no gene flow or constant gene flow since divergence. However, putative hybrids did not exhibit intermediate leaflet morphology, which could be related to distinct selective pressures maintaining species integrity even in the face of gene flow. Our results suggest that despite morphological differences between savanna and forest species, interspecific barriers to gene flow might not be fully developed between vicariant tree species and that interspecific hybridization in trees from Cerrado biome may be an underdiagnosed process.

“…Fabaceae ou Leguminosae possui distribuição Pantropical, apresentando 727 gêneros e cerca de 19.325 espécies que ocorre em todo o Brasil, sendo considerada a terceira maior família de Angiospermas (LPWG, 2017) e uma das famílias botânicas mais representativas do Domínio Cerrado. Hymenaea é um gênero que apresenta cerca de 19 espécies que apresentam porte arbóreo e arbustivo, ocorrendo desde florestas úmidas e ambientes alagados até ambientes mais secos, como o Cerrado e a Caatinga (RIBEIRO et al, 2015;BFG, 2015).…”

RESUMO As diferenças biométricas dos frutos e sementes são características que fornecem informações para exploração e conservação da espécie, podendo estar relacionadas a fatores ambientais e genéticos. Diante disso, objetivou-se avaliar a biometria de frutos, sementes e a emergência de plântulas de Hymenaea courbaril (jatobá-damata) e H. stigonocarpa (jatobá-do-cerrado). Foi avaliada a biometria dos frutos e sementes de cinco matrizes, determinando o comprimento e a largura de frutos e sementes, a massa, o volume e a densidade de mil sementes, a porcentagem e o índice de velocidade de emergência. Os frutos e sementes de H. courbaril foram maiores do que em H. stigonocarpa, já a massa, volume, densidade, porcentagem e índice de velocidade de emergência não diferiram entre as espécies. Conclui-se que as diferenças biométricas entre os frutos e as sementes podem ser utilizadas como uma ferramenta de separação das espécies em campo, mas não altera a taxa e a velocidade de emergência das plântulas.
