FITOSSOCIOLOGIA DO COMPONENTE ARBÓREO DE UM FRAGMENTO DE FLORESTA OMBRÓFILA MISTA MONTANA, CURITIBA, PR, BR

A phytosociological study on the tree, species of the Mixed Ombrophilous Montane Forest at Barigüi Park, Municipality of Curitiba, Paraná State, Brazil, was carried out. The sampling method used was the point-centered quarter method. The criterion of inclusion adopted was: trees with PBH between 10 and 29 cm for the lower size stratum, and equal or above 30 cm for the higher size stratum. In total, 150 centered points were established. In the first group (the lower one) were found 77 species and 34 families, and in the second group 67 species and 32 families. In both groups, the richest families were Myrtaceae (17 species) and Lauraceae (eight). The highest diversity was found in the group with smaller size due to species association of both strata (species exclusive from the lower stratum and species from the higher stratum represented by young individuals).Realizou-se o estudo fitossociológico das espécies arbóreas da Floresta Ombrófila Mista Montana localizada no Parque Municipal do Barigüi, Curitiba, PR. Utilizando-se o método de quadrantes (pontos), foram alocados 150 pontos e amostrados indivíduos com perímetro do tronco à altura do peito (PAP) entre 10 e 29 cm, para a caracterização das espécies de menor porte, e PAP igual ou superior a 30 cm, para a caracterização das espécies de maior porte. No primeiro grupo foram registradas 77 espécies e 34 famílias, e no segundo, 67 espécies e 32 famílias. Em ambos os grupos, as famílias mais ricas em espécies foram Myrtaceae (17) e Lauraceae (oito). Encontrou-se maior diversidade no grupo de menor porte, resultante da associação das espécies com ocorrência exclusiva no estrato inferior e daquelas representadas por indivíduos em regeneração natural, representantes do grupo das espécies de maior porte que constituem o estrato superior da floresta

COMPOSIÇÃO FLORÍSTICA DA FLORESTA OMBRÓFILA MISTA MONTANA DO PARQUE MUNICIPAL DO BARIGÜI, CURITIBA, PR

Floristic composition of the Mixed Ombrophilous Montane Forest at Barigüi County Park, Parana, Brazil. The checklist (except epiphytes) of a subtropical ombrophilous montane forest at Barigüi Park, Curitiba County, listed 390 species, 226 genera and 99 families (pteridophytes, gymnosperms and angiosperms). The best-represented pteridophytes families were Dryopteridaceae (eight species) and Blechnaceae (six species) the angiosperms were Asteraceae (30 species), Solanaceae (25 species), Myrtaceae (25 species) and Poaceae (17 species). The gymnosperms were represented by two families only (Araucariaceae and Podocarpaceae) each one with one specie. We listed 141 trees, 129 herbs, 67 bushes, 50 vines and tree hemiepiphytes. Even thought being inside the city and showing significant anthropic influence the forest had a high floristic diversity.Realizou-se o levantamento florístico das espécies vasculares (exceto epífitas) de um fragmento de Floresta Ombrófila Mista Montana localizado no Parque Municipal do Barigüi, município de Curitiba, PR.

As gimnospermas foram representadas por somente duas famílias, Araucariaceae e Podocarpaceae, cada uma delas com uma espécie. Foram listadas 141 espécies arbóreas, 129 herbáceas, 67 arbustivas, 50 trepadeiras e três hemiepífitas. A floresta, apesar de situada dentro de uma zona urbana, sujeita à intensa interferência antrópica, apresentou elevada riqueza específica

Composition, diversity and geographical distribution of vascular plants of an Atlantic Rain Forest, Southeastern Brazil

In the Montane and Submontane Rain Forest of the Carlos Botelho State Park - PECB (ca. 37,000 ha) the composition, richness and geographical distribution of native, vascular forest species was evaluated. The analysis of 1143 species of 140 families supported the pattern found for other forests of Eastern Brazil, showing high species richness of Myrtaceae (85 species), Orchidaceae (81), Fabaceae (57), Asteraceae, Melastomataceae (54), Lauraceae (53), Rubiaceae (51), Bromeliaceae (43), Piperaceae (30) and Solanaceae (25), besides ferns (123). The most species-rich genera were Eugenia (34), Ocotea (26), Leandra, Myrcia, Vriesea (18), Piper, Solanum (16), Miconia (14), Mollinedia (13), and Peperomia (12). The richness and composition varied greatly among life forms, as well as the number of families represented in each one of them (only Rubiaceae had species in all life forms, except parasites). Trees had the largest contribution of total richness (39.1%), a value that represented more than 20% of the species listed for the whole Atlantic Forest of Southeastern Brazil. Trees were followed by epiphytes (22.4%), herbs (18.4%), shrubs (10.1%), lianas (9.1%), and parasites (0.9%). The overall richness and composition of life forms was quite close to other neotropical forests (e.g. high contribution of ferns among epiphytes), although some life forms remain undersampled in the PECB (mainly herbs, lianas and epiphytes). The occurrence of species endemic to the Atlantic Forest was pronounced (65%), with a predominance of species restricted to the Southern Atlantic Forest (43%). Pantropical species were rare (2%), being more common among ferns. Myrtaceae and Melastomataceae were the families with greater number and proportion of endemic species

A list of land plants of Parque Nacional do Caparaó, Brazil, highlights the presence of sampling gaps within this protected area

Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
