Abstract The eu-bromelioid clade provides a classic example of an exceptionally rapid radiation, in which many closely related species are found sympatry. In this respect, cohesion may be due to the evolution strong reproductive barriers, although interspecific and intergeneric hybridization is observed family. objective study was characterize breeding systems post-pollination barriers Wittmackia patentissima Hohenbergia ridleyi. Previously included Aechmea, they show almost complete absence...

We describe a new species of Hohenbergia (Bromeliaceae) from Brazil, H. ituberaensis, rare species, so far only known Ituberá municipality, Bahia State, in an area the Atlantic Forest. The is similar to stellata, presenting pinkish inflorescence, congested and non-divided branches, large floral bracts hiding sepals, spatulate petals with slightly reflexed apex. However, it differs by white petals, as diagnostic characteristic. type specimen was collected small forest fragment here this...

Hohenbergia correia-araujoi Pereira & Moutinho is a member of the Bromeliaceae widely used in gardening, endemic to Bahia state (Brazil), rarely collected since its description 1980. Although species an ornamental bromeliad, detailed occurrence range and ecological morphological traits are poorly known. In this paper, we present rediscovery natural populations correia-araujoi, adding information about habitat, habit, plant shape, presenting new comparisons geographical distribution species,...

We here establish the Hohenbergia capitata complex composed of three species endemic to Atlantic Forest, in State Bahia, Northeastern Brazil. When compared with other is recognized by small size plants (shorter than 1 m tall when flowering), lanceolate leaf blades, inflorescence main axis short and congested branches, concentrated on apical portion (creating a capitulate shape), primary branches pedunculate (short stipes), basal bracts sub-orbicular, large flowers (over 3 cm long) spatulate...

We describe a new species from Rio Grande do Norte (Brazil), Hohenbergia densa, that inhabits the dry vegetation of state. This can be recognized by its short and robust habit, differing other Caatinga-endemic region, commonly present broader rosette with long inflorescence axis. Additionally, we provide illustrations, phenology, map occurrence, table morphological comparisons similar taxa.

We present two new species, Hohenbergia alba and H. sparsiflora, endemic to the Brazilian Atlantic Forest in southern region of state Bahia. These species were identified as understory epiphytes forest fragments near highways. newly described are morphologically similar “giant group”, characterized by their significantly larger size compared found highlands dryer environments. Notable unique features include compact rosette a 3-4-branched inflorescence with white-colored petals for...

The authors describe, discuss, and illustrate Tillandsia itatiensis, a new species from the Caatinga biome in municipality of Itatim, Bahia, Brazil. is similar to T. streptocarpa grao-mogolensis, regarding morphological characters such as caulescent habit, curved stem, simple inflorescence with no more than five flowers per simple-erect stigma. It inhabits inselbergs forest, where it critically endangered (CR) due its small distribution human extractivism.

We present the first records of five Tillandsia L. species from state Bahia, Brazil, which were collected in field and studied herbaria. didisticha (E.Morren) Baker occurs Cerrado Caatinga biomes, T. line­aris Vell. dura Atlantic Forest fragments, pruinosa Sw. grao-mogolensis Silveira an ecotonal transition zone between dry humid forest. photographs, taxonomic notes, distribution ranges these Bahia discuss their morphological distinctions.

Apesar do tema domínios Brasileiros está inserido como temática geradora nos componentes curriculares de Ciências e Geografia. Sabe-se que os conhecimentos adquiridos por parte dos estudantes referente a Caatinga são considerados supercificais, visto muitas vezes, este assunto é abordado forma vaga, havendo uma preferência para ambientes mata verde, acarretando ausência conhecimento sobre sua complexidade importância. Nesse sentido, o presente estudo teve objetivo identificar analisar as...

The authors describe Hohenbergia ymboreorum, a new green-flowered species of Bromeliaceae from Bahia state. was found growing in the municipality Vitoria da Conquista as terrestrial highland transitional area between Atlantic Forest and Caatinga vegetation. This is morphologically related to H. minor augusta, but can be easily distinguished by its sparsely white-lanate inflorescence indument, longer narrower leaves, smaller flowers, with golden-brown floral bracts not hiding sepals, erect...

Este trabalho teve como objetivo a aplicação de uma Sequência Didática (SD) para sensibilização ambiental estudantes da Educação Básica (EB) sobre as bromélias e sua importância manutenção biodiversidade. As atividades foram desenvolvidas em 04 turmas EB (Infantil III IV, 4º 9º ano do ensino fundamental), durante um semestre letivo, por meio projetos multidisciplinares, utilizando 10 etapas SD plano base todas (com adaptações pertinentes cada turma). planejadas abordagens projetos, abordagem...

A Percepção Ambiental (PA) pode ser utilizada como uma ferramenta eficiente para diagnosticar as informações prévias de um determinado grupo, e são relevantes planejar executar ações educação ambiental. O objetivo deste trabalho foi analisar a percepção estudantes da básica comunidades litorâneas metropolitanas em relação ao Ambiente Marinho (AM), dando ênfase nos conhecimentos fauna conservação. pesquisa desenvolvida com 65 alunos do 2° ano ensino médio, três escolas públicas Rio Grande...

The authors describe, discuss, and illustrate two new species of Tillandsia from a granitic outcrop in the municipality Petrópolis, Rio de Janeiro state, an inselberg located Belo Jardim, Pernambuco Brazil. are endemic with restricted area distribution, being considered critically endangered (CR) mainly due to habitat fragmentation illegal extractivism, specifically for regional international trade. We also present phenology, distribution map species, compare them morphologically similar taxa.
