Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with publication Plants Fungi Catalogue, has been since by more than 430 specialists working online. Brazil home to 32,086 native Angiosperms 23 Gymnosperms, showing an increase 3% its species richness relation 2010. The Amazon Rainforest richest biome for while Atlantic one Angiosperms. There was a considerable increment number...
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....
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...
Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys biodiversity inventories. Atlantic Forest, most endangered ecosystems world, have high endemism radiated recently Pliocene. We aimed to (1) compile an extensive Forest data set on vascular, non-vascular plants (including hemiepiphytes), lichen epiphyte species occurrence abundance; (2) describe distribution order indicate future sampling efforts. Our work presents first with information abundance...
The authors describe, discuss, and illustrate Lymania involucrata, a new ornamental species from the Atlantic Forest in municipality of Igrapiúna, Bahia, Brazil, here considered critically endangered species. is morphologically related to L. brachycaulis but clearly diffe According Sousa rs it by well-developed, involucral primary bracts distinct shape size inflorescence, branches, flowers. A map distribution taxonomic comments are presented.
The authors describe, discuss, and illustrate Tillandsia oliveirae, a new species from the inselbergs of Caatinga biome in municipality Itatim, Bahia, Brazil. is similar to T. hofackeri, differing by morphological characters such as larger size plant, longer peduncle, more laxly arranged leaves, which are numerous, whitish petals. It an endemic with restricted area distribution, being considered critically endangered (CR) due illegal extractivism, specifically for regional international trade.
ABSTRACT The genus Wittmackia has 44 species distributed in two centers of diversity: the Brazilian clade and Caribbean clade. includes 29 species, with geographic distribution concentrated Northeast Brazil. This study reports morphology, ultrastructure, pollen viability stigma receptivity by different microscopy techniques 23 endemic to Brazil occurring Atlantic Forest areas. Pollen morphology was evaluated scanning electron light weak lactic acetolysis method. Histochemical tests were...
We describe, discuss, and illustrate Dichorisandra fadenii, a new species endemic in an area of southwestern Amazonia (Brazil, Peru Bolivia). The can be differentiated from its congeneric by having villose stem leaves, whitish flowers with six stamens, yellowish anthers, opening 2 apical pores, lanceoloid, acuminate fruits. Discussion relevant characters, comparisons similar species, description, distribution map, illustrations are provided. is assessed as ‘Vulnerable’, due to restricted...
We describe, discuss, and illustrate Vriesea serraourensis, a new species from the Chapada Diamantina in municipality of Barra da Estiva Ituaçu, Bahia, Brazil, here considered critically endangered species. The is morphologically related to V. bahiana but clearly differs it by its larger size, longer fewer leaves, inflorescence branches forming an internal angle 30o–45o with main axis, sepals yellow ovate, petals narrowly obovate, whitish-yellow towards base at apex, basal petal appendages...
Three new species of Angiosperms have been found in four short collection trips to the same protected reserve—“Estação Ecológica Estadual de Wenceslau Guimarães”—and neighboring areas Atlantic Forest south Brazilian state Bahia. These belong three genera from distinct lineages family Melastomataceae: Huberia , Meriania and Physeterostemon . The description these represent a good example Linnean shortfall, i.e., absence basic knowledge about biodiversity area, as well tropical forests whole....
Abstract Climate change, together with human activities, impacts on natural and systems all continents poses a major threat to biodiversity, especially in environments high rate of endemism where species are profoundly adapted specific environmental conditions, as is the case seasonally dry tropical forests, noticeably Caatinga, an exclusively Brazilian biome. The objective this study was build spatial niche models five Cactaceae ( Arrojadoa penicillata , Brasilicereus phaeacanthus Pereskia...
Abstract Tillandsia is the bromeliad genus containing largest number of species, with wide geographic dispersion and an important ecological role in ecosystems. Investigations pollen morphology are to support taxonomic conservation studies as well choose promising species for cross‐pollination obtain hybrids. The objective this study was evaluate morphology, production, viability grains 24 that naturally occur state Bahia, Brazil. Pollen were acetolized analyzed by scanning electron...
Two new species of Dichorisandra collected in Rio de Janeiro state are described based on studies the field, herbarium specimens and cultivated plants. odorata can be distinguished by its small stature, leaves congested at apex stems, with lamina densely pilose both sides, fragrant flowers (unusual for genus), six anthers connectives dehiscent an apical pore; nana resembles D. thyrsiflora presence yellow pores, however it differs being smaller, reaching only 30 cm tall, position stamens...
Although Brazil is the centre with third highest diversity of Cactaceae, distribution species at local scale in remains largely unknown. This article describes patterns Cactaceae communities protected area Contendas do Sincorá National Forest (CSNF) a semiarid region north-east Brazil. Trails were distributed between altitudes 290 and 596 m, along which 91 plots (1.8 ha) established for quantitative surveys. The floristic data also recorded separately on these trails. With survey, 18 taxa...
