Abstract The Global Strategy for Plant Conservation (GSPC) was established by the Conference of Parties in 2002 to decrease loss plant diversity, reduce poverty and contribute sustainable development. To achieve this overarching goal, GSPC has a series targets, one which is ensure that diversity well understood, so it can be effectively conserved used manner. Brazil hosts more than 46,000 species plants, algae fungi, representing most biodiverse countries on Earth, playing key role GSPC....
A comprehensive new inventory of Brazilian plants and fungi was published just in time to meet a 2010 Convention on Biological Diversity target offers important insights into this biodiversity's global significance. Brazil is the home world's richest flora (40,989 species; 18,932 endemic) includes two hottest hotspots: Mata Atlântica (19,355 species) Cerrado (12,669 species). Although total number known species one-third lower than previous estimates, absolute endemic vascular plant higher...
Abstract The shortage of reliable primary taxonomic data limits the description biological taxa and understanding biodiversity patterns processes, complicating biogeographical, ecological, evolutionary studies. This deficit creates a significant impediment to research conservation planning. crisis are widely recognized, highlighting urgent need for data. Over past decade, numerous countries worldwide have devoted considerable effort Target 1 Global Strategy Plant Conservation (GSPC), which...
Abstract This compilation of ferns and lycophytes in Brazil is an update the one published 2010 Catálogo de Plantas e Fungos do Brasil. The methodology consisted collecting data from regional checklists, taxonomic revisions, selected databases. Invited specialists improved list accessing a website housed at Jardim Botânico Rio Janeiro. results show 1,253 species: 1,111 142 lycophytes. number 6.5% higher than previous (1,176 spp.). percentage endemic species decreased 38.2% to 36.7%. We...
Resumo O estado do Rio de Janeiro, inserido no Bioma Mata Atlântica, representa uma área com alta diversidade paisagens vegetacionais, habitats e espécies plantas, incluindo várias endêmicas. A flora Janeiro é reconhecidamente das mais ricas país o apontado como um importante centro endemismo. Tais características têm incentivado os diferentes estudos botânicos, destacando Vellozo, Cysneiros, Glaziou, Gardner, entre outros, naturalistas precursores na exploração florestas nativas....
Abstract Based on an analysis of five plastid markers ( atpA , atpB rbcL rps4‐trnS trnL/trnL‐trnF ), we show that Diplazium lechleri is sister to a clade formed by the Hemidictyaceae and Aspleniaceae. Thus, it does not belong Athyriaceae where previously classified. A new family, Desmophlebiaceae, genus, Desmophlebium are described accommodate this relationship. Morphologically, distinguished from combination thick 1‐pinnate laminae, entire pinnae, decurrent distal conform lamina apices...
O presente trabalho trata do levantamento da flora pteridofítica Mata Colônia, Chuva e Reserva, no município de Bonito (Pernambuco, Brasil). local é um brejo altitude (ca. 700-800m), cuja vegetação diferenciada Caatinga típica região, condicionada principalmente pela elevada, posição geográfica aspectos climáticos que favorecem o desenvolvimento das pteridófitas. Foram realizadas 17 excursões ao com objetivo coleta observação espécies pteridófitas, sendo acrescentadas aos acervos herbários,...
O Parque Nacional da Restinga de Jurubatiba, localizado no norte do Estado Rio Janeiro, abrange os municípios Macaé, Carapebus e Quissamã. Foram registradas para a área estudo 12 famílias com 21 gêneros 32 espécies. As encontradas foram Blechnaceae, Cyatheaceae, Davalliaceae, Dennstaedtiaceae, Dryopteridaceae, Gleicheniaceae, Lycopodiaceae, Polypodiaceae, Pteridaceae, Salviniaceae, Schizaeaceae Thelypteridaceae. Dessas, as mais representativas em número espécies Polypodiaceae (5 spp.)...
A restinga de Praia das Neves ocupa uma extensa área (ca. 67 km2) no extremo sul do Estado Espírito Santo (21°14′35.35″S e 40°56′48.68″W), limitada pelo Rio Itabapoana, na divisa com o Janeiro. O objetivo desse estudo foi identificar caracterizar as diferentes formações vegetais dessa sua flora associada, incluindo reconhecimento dos habitats relacionados ao lagarto ameaçado extinção Liolaemus lutzae Mertens, 1938. Excursões para caracterização da local foram realizadas em campanhas...
A community of Ferns and Lycophytes was investigated by comparing the occurrence species on different slopes a paleoisland in Southeastern Brazil. Our goal to evaluate hypothesis that with geographic orientations determine differentiation Atlantic Forest ferns lycophytes community. We recorded these plants at turned towards continent open sea. Analysis consisted preliminary assessment fern beta diversity, Non Metric Multidimensional Scaling (NMDS) Student t-test confirm if sites sampling...
Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of 36 global biodiversity hotspots. A major challenge improving actions is to know richness, by these areas. Online databases offer an accessible way build species lists and provide relevant information about biodiversity. list land plants "Parque Nacional do Caparaó" (PNC) was previously built using online published on website "Catálogo de Plantas das Unidades Conservação Brasil." Here, we...
O presente trabalho apresenta o levantamento das pteridófitas ocorrentes na Pedra de Itacoatiara, afloramento rochoso localizado no Parque Estadual da Serra Tiririca, litoral do Município Niterói, Estado Rio Janeiro, Brasil.

The palynological diversity of Blechnaceae in the Atlantic Forest was investigated. While monophyletic family belongs to group leptosporangiate ferns, a new classification proposed by recent phylogenetic study reorganizes and adds genera. To expand knowledge group, spore morphology 23 species hybrid, distributed among 10 genera, described. Material from herbarium collections were submitted acetolysis mounted on slides, with subsequent statistical analysis measurements. Photomicrographs...
Brazil is one of the most biodiverse countries in world, with about 37,000 species land plants. Part this biodiversity within protected areas. The development online databases last years greatly improved available data. However, existing do not provide information areas which individual plant occur. lack such a crucial gap for conservation actions. This study aimed to show how captured from databases, cleaned by protocol and verified taxonomists allowed us obtain comprehensive list vascular...

The Blechnaceae is a family of leptosporangiate ferns with wide geographical distribution. Recent phylogenies revealed several lineages within the family, culminating in classification system comprising 25 recognized genera grouped into three subfamilies. Spore surface morphology has major importance taxonomy group, but there limited information on relevance other palynological characters. This study aimed to examine whether spore aids distinguishing according current phylogenetic...
The genus Polystichum presents striking variation in morphology and habitat preference the Central Andes, Serra do Mar, adjacent regions. Among these taxa, montevidense is a name long applied to an array of twice-pinnate species with dark petiole scales, broad leaves, no vegetative propagules. Using classical morphological approach combined inferences gleaned from molecular data, we analyzed P. its widespread ecologically prominent allies. Results our analysis suggest should be collections...
Trindade is an oceanic archipelago situated roughly 1140 km east of Espírito Santo State, Brazil. It reaches altitude 620 m a.s.l. and covers approximately 10 km2. Less than 5% the island covered by forest 60% herbaceous vegetation. Several new endemic plant taxa were described in 1960's, some these had not been registered since then.
