Two new species of Eugenia sect. Phyllocalyx (Myrtaceae) from Brazil
Bünger, Mariana de Oliveira; Mazine, Fiorella Fernanda; Stehmann, João RenatoTwo new endangered Brazilian species of Eugenia are described and illustrated, E. magnisepala and E. salacifolia . Eugenia magnisepala , collected in Matas de Cipó (liana forests) in the northeastern state of Bahia, is recognisable by its larger calyx lobes, membranaceous blades and costate ovary, traits not shared with the morp- hologically similar species E. itacarensis , E. involucrata, E. macrobracteolata a...
The evolutionary history of Eugenia sect. Phyllocalyx (Myrtaceae) corroborates ...
Bünger, Mariana de Oliveira; Mazine, Fiorella Fernanda; Forest, Félix; Bueno, Marcelo Leandro; Stehmann, João Renato; Lucas, Eve J.Background and aims: Eugenia sect. Phyllocalyx Nied. includes 14 species endemic to the Neotropics, mostly distributed in the Atlantic coastal forests of Brazil. Here the first comprehensive phylogenetic study of this group is presented, and this phylogeny is used as the basis to evaluate the recent infrageneric classification in Eugenia sensu lato (s.l.) to test the history of the evolution of traits in the gr...
Myrtaceae throughout the Espinhaço Mountain Range of centraleastern Brazil: flo...
Bünger, Mariana de Oliveira; Stehmann, João Renato; Oliveira-Filho, Ary TeixeiraAlthough biological surveys and taxonomic revisions provide key information to ecological and evolutionary studies, there is a clear lack of floristic and phytogeographic studies of the mountainous regions of Brazil, which harbor some of the most threatened plant ecosystems on the planet. Myrtaceae has been reported to be one of the most important families in the upland areas of Brazil, as well as in the Atlant...
Circumscription and synopsis of Eugenia section Speciosae Bünger & Mazine (Myrt...
Bünger, Mariana de Oliveira; Mazine, Fiorella Fernanda; Lucas, Eve J.; Stehmann, João RenatoA new section of Eugenia (Myrtaceae) is described, segregate from Eugenia sect. Phyllocalyx. Phylogenetic studies suggest that Eugenia sect. Phyllocalyx as traditionally delimited is paraphyletic. To maintain the monophyly of each of the sections in Eugenia s.l., we herein opt to circumscribe a new section and recognize six taxa in sect. Speciosae, which has a distribution mostly in southeastern Brazil and nort...
Amazon plant diversity revealed by a taxonomically verified species list
Cardoso, Domingos; Särkinen, Tiina E.; Alexander, Sara; Amorim, André Márcio Araújo; Bittrich, Volker; Celis, Marcela; Daly, Douglas CharlesRecent debates on the number of plant species in the vast lowland rain forests of the Amazon have been based largely on model estimates, neglecting published checklists based on verified voucher data. Here we collate taxonomically verified checklists to present a list of seed plant species from lowland Amazon rain forests. Our list comprises 14,003 species, of which 6,727 are trees. These figures are similar to...
New initiatives for Brazilian aquatic plant data management
Pivari, Marco Otávio Dias; Melo, Pablo Hendrigo Alves de; Souza, Filipe Soares; Stehmann, João Renato; Moura Júnior, Edson Gomes deInitiatives directed at managing information on aquatic plants can support different areas of scientific research, educational practices and political decisions for sustainable management and protection of wetlands and natural resources, as well as reveal knowledge gaps regarding aquatic plants and wetlands. Furthermore, such initiatives can contribute directly to consolidating wetland classification systems in...
Biodiversity conservation gaps in the Brazilian protected areas
Oliveira, Ubirajara; Soares-Filho, Britaldo Silveira; Paglia, Adriano Pereira; Brescovit, Antonio D.; Carvalho, Claudio J. B. de; Silva, Dasniel PaivaAlthough Brazil is a megadiverse country and thus a conservation priority, no study has yet quantified conservation gaps in the Brazilian protected areas (PAs) using extensive empirical data. Here, we evaluate the degree of biodiversity protection and knowledge within all the Brazilian PAs through a gap analysis of vertebrate, arthropod and angiosperm occurrences and phylogenetic data. Our results show that the...
