title: Flora of the canga of the Serra dos Carajás, Pará, Brazil: Piperaceae

description: Abstract Aiming to increase the knowledge concerning the canga vegetation of the Serra dos Carajás, a taxonomic treatment of the Piperaceae species was prepared. Thirty species were recorded for the region, of which 20 taxa were found growing on canga substrate (ferruginous rupicolous vegetation). The majority of the species studied belong to Piper (23 species). The first record of P. goeldii for the state of Pará is presented, while the fruit of P. pellitum is described for the first time. Two out of seven Peperomia species studied - P. albopilosa and P. pseudoserratirhachis are described as new. Identification keys, detailed descriptions, geographical distribution and comments for taxa, besides illustrations of those poorly known or that are reported for the first time in the region, are provided.

title: Flora of the canga of the Serra dos Carajás, Pará, Brazil: Poaceae

description: Abstract This work presents a taxonomic treatment for the Poaceae in the canga of the Serra dos Carajás, Pará state, Brazil. The article was prepared according to the guidelines of the project Flora of the canga of the Serra dos Carajás, based on the study of the specimens from the herbaria BHCB, MG and UB. A total of 87 species belonging to 37 genera were inventoried. Among these, Axonopus carajasensis, Paspalum cangarum, P. carajasense and Sporobolus multiramosus are considered endemic to the canga of the Serra dos Carajas; two new species are to be published soon (one of Paspalum and one of Hildaea); and one species of Trichanthecium is under study to determine its taxonomic identity. Six species are recorded for the first time in Pará state. Morphological descriptions, identification keys, illustration of the spikelets, photo plates, detailed geographic distribution and diagnostic comments are provided for all species treated.

title: Ferns and lycophytes from Serra dos Carajás, an Eastern Amazonian mountain range

description: Abstract In the state of Pará (Brazil), until the beginning of last decade little was known about the composition of the fern and lycophyte flora. The ferruginous mountains of Carajás are located in Southeastern Pará, mostly inserted in the Floresta Nacional de Carajás. The objective of this work is to present a complete and updated list of fern and lycophyte species occurring in all vegetation types from Carajás ferruginous mountains as a contribution to the knowledge of these plant groups from the Brazilian Amazon. The species list was based on specimens collected between 2007 and 2013. About 1068 specimens deposited in the BHCB Herbarium were studied. A total of 186 species of pteridophytes were recorded, 175 species of ferns distributed in 22 families and 68 genera, and 11 species of lycophytes distributed in three families and four genera. The fern and lycophyte flora of Serra dos Carajás region corresponds to 64% of the Pará state flora of these groups and 34% of the Brazilian Amazon fern and lycophyte flora. Seven taxa are presented as new records for Pará state: Asplenium abscissum, A. otites, A. praemorsum, Blechnum lanceola, Elaphoglossum minutum, Doryopteris collina, and Hemionitis tomentosa. Three species are endemic to Serra dos Carajás, Isoetes cangae, I. serracarajensis, and Selaginella stomatoloma.

title: Bryophytes (Bryophyta and Marchantiophyta) of the canga of the Serra dos Carajás, Pará, Brazil

description: Abstract The Botanical studies in Serra dos Carajás initiated in the late 60’s. Thereafter, several papers on floristics, ecology and phytogeography were published, which resulted in many discoveries about the local flora, culminating in the production of the flora of the canga of the Serra dos Carajás. This work aims to present the richness of the bryophytes studied during the Flora of the canga of the Serra dos Carajás, Pará, Brazil. The studied material included new collections from 2015 to 2017 and specimens deposited in Herbarium MG. The canga presented a high bryophyte richness (54 mosses and 35 liverworts) and the composition was the expected for rupestrian areas in Amazonia. The high richness of shade specialists has shown that the few trees in the canga as well as the small areas of low forests forming vegetation islands or even specific niches such as cracks and base of rocks or spaces under rocks, serve as refuge for these species. The study of the bryophytes in the Serra dos Carajás made it possible to discover 51 new records for the canga of Carajás, seven for Pará, three for the North Brazilian region, and one for Brazil.

title: Brazilian efforts towards achieving a comprehensive extinction risk assessment for its known flora

description: Abstract Brazil houses nearly 36,400 native terrestrial plant species. The country is a signatory of the Global Strategy for Plant Conservation (GSPC) and has to develop tools to achieve GSPC targets. Target 2 states that countries must undertake risk assessments of its entire known plant species by 2020. Here, we offer a panorama on how far has Brazil gone towards achieving this target. We compiled data on all risk assessments for plant species ever made in the country and produced the first synthesis of results with respect to these assessments. We found that the Brazilian Red List Authority for plants has assessed the extinction risk of 5,646 species so far, which corresponds to 15.5% of all known flora in Brazil. Among these species, 2,738 (48%) are currently threatened. Those species are distributed across all Brazilian Biomes and states. Families with the highest number of threatened species are Asteraceae and Bromeliaceae. We conclude that Brazil is far from achieving GSPC target 2 by 2020. However, given the enormous flora of the country and the huge amount of effort and resources put into this particular task, Brazil is following a good path towards a reliable assessment of it entire flora.

title: Ex situ conservation of threatened plants in Brazil: a strategic plan to achieve Target 8 of the Global Strategy for Plant Conservation

description: Abstract With increasing rates of habitat destruction and species loss, ex situ conservation is gaining global momentum and reluctance in relying on ex situ conservation is rapidly giving way to a more optimistic, strategic view. Target 8 of the Global Strategy of Plant Conservation calls for at least 75 percent of threatened plant species in accessible ex situ collections, preferably in the country of origin, and 20 percent of them included in recovery and restoration programs. Here, we provide updated information on Brazil's progress towards Target 8 through a nationwide examination of how many threatened species were conserved in ex situ collections in Brazil. Our data comprised whole plants (living collections), seed (seed banks) and tissue cultures (in vitro). Of the 2,113 threatened species, at least 452 (21.4%) species were conserved in ex situ collections, an increase in 4% of living organisms and 96% of seeds when compared to a previous assessment. Since it is unlikely Brazil will achieve Target 8 by 2020, we also discuss public policies and strategies to help overcome key bottlenecks preventing its achievement and propose revised goals for the GSPC 2020-2030.

title: Amazon canga: the unique vegetation of Carajás revealed by the list of seed plants

description: Abstract The Floresta Nacional de Carajás (FLONA of Carajás) and the Parque Nacional dos Campos Ferruginosos (PNCF) are home to canga vegetation where 856 species distributed in 116 families of seed plants were recorded. The richest families were Poaceae (86), Fabaceae (65) and Rubiaceae (46) and the best represented habit was herbaceous. Two genera, 24 species and one subspecies are considered endemic from the canga of the studied area. Within the FLONA of Carajás, the Serra Norte was the best sampled site, and is home for 659 species of seed plants, while 545 species were recorded for the Serra Sul. Approximately 60% of the species documented, including the endemics, have no record within the PNCF. Through the taxonomic list here presented, it was possible to demonstrate considerable distinction between the canga of the Serra dos Carajás and the same formation in the Quadrilátero Ferrífero, in Minas Gerais, with little correspondence between these two lists and the one from Corumbá, Mato Grosso do Sul state. The richness and singularity of the regional flora, which includes many endemisms, associated to the current threats to these environments due to mineral exploration, point to the need for careful and consistent planning to ensure the conservation of the flora of the canga of Carajás.
