Many Brazilian Atlantic Rainforest plant and animal species are geographically restricted to Southern Bahia and Northern Espírito Santo States. We investigated the geographic distribution of epiphytic bromeliads in the lowland forest of the Una region (15° 17' 34' S -39° 04' 30'' W) in Southern Bahia. Specifically, we addressed the following questions: i) what is the extent of each species distribution?; and ii) are the Bromeliaceae subfamilies distributed differently from one another? Almost half of the 40 species (47.5%) occur exclusively in the Southern Bahia-Northern Espírito Santo region and are herein referred as endemic species. The highest percentage of the 15 species of Tillandsioideae (46.7%) occur throughout the South American Continent and most of the 25 species of Bromelioideae (68.0%) are mainly represented by endemic species. The Una region has almost two times more species than a forested area located 40 km west, suggesting marked increases in diversity in over relatively short distances. The endemism data around Una indicates that species are geographically distributed over an area spanning approximately six to seven degrees in latitude and longitude. This result contrasts with the geographic distribution of Andean epiphytes, mainly represented by Tillandsioideae, that have large geographical distributions. Larger-scale analyses and standardized methods are necessary to verify whether the narrow geographical distribution of most epiphytic bromeliads in the Una region is consistent across different forest types of the Atlantic Rainforest. Resumo: Na Floresta Atlântica, muitas espécies vegetais e animais são geograficamente restritas à região do Sul da Bahia e Norte do Espírito Santo. A distribuição geográfica das bromélias epífitas da floresta de planície da região de Una, Sul da Bahia (15° 17' 34' S -39° 04' 30'' W), foi investigada para responder às seguintes questões: i) qual a extensão da distribuição geográfica das espécies?; e ii) existe diferença na distribuição geográfica das subfamílias de Bromeliaceae? Quase metade (47,5%) das 40 espécies ocorre exclusivamente na região entre o Sul da Bahia e o Norte do Espírito Santo, aqui chamadas de endêmicas. A maior percentagem das 15 espécies de Tillandsioideae (46,7%) ocorre através do Continente Sul-Americano e a maioria das 25 Bromelioideae (68,0%) é principalmente representada por espécies endêmicas. Una possui quase duas vezes mais espécies que a região de Jussari que se localiza aproximadamente 40 km à oeste, sugerindo que a diversidade desta comunidade aumente rapidamente em uma pequena extensão geográfica. Os dados de endemismo das epífitas de Una indicam que as espécies estão distribuídas através de uma área geográfica de aproximadamente seis a sete graus quadrados. Este resultado contrasta com a distribuição geográfica das epífitas andinas, que são representadas principalmente por Tillandsioideae de ampla distribuição. Análises de larga escala e com metodologias padronizadas são necessárias para verificar se a pequena distribui...

Seed dispersal and population structure in Vriesea gigantea, a bromeliad from the Brazilian Atlantic Rainforest

Seed dispersal, population structure and the mating system of plant species can have great consequences on the genetic structure of populations. Vriesea gigantea is a bromeliad from southeastern Brazil which is self-compatible and pollinator dependent for fruit set. Its populations are fertile in terms of the production of flowers, pollen, fruits and seeds. To assess the importance of seed supply for gene flow, colonization and distribution of adult individuals, the seed dispersal and population structure of V. gigantea were studied. Seeds are dispersed over short distances; most seeds land close to the mother plant. This pattern coincides with the reported aggregate distribution of bromeliad seedlings. Population structure results showed high seedling recruitment, because 51.3% developed into adults, although few juveniles reached this stage. This result is different from that for other bromeliad species from different habitat conditions. Seed dispersal and population structural patterns are consistent with previous molecular studies, revealing that V. gigantea populations are genetically structured, with low gene flow and a moderate outcrossing rate.

“…After Smith & Downs (1979), taxonomic work within Aechmea has concerned mostly description of new taxa, sometimes on the basis of minor morphological variation. Published taxonomic revisions dealing with Aechmea and other genera of Bromelioideae are scarce (Wendt, 1997; Canela, Paz & Wendt, 2003; de Sousa & Wendt, 2008).…”

Considerable taxonomic confusion exists among species of Aechmea subgenus Macrochordion (Bromeliaceae), which comprises the A. bromeliifolia complex. Cluster and principal components analyses were performed in order to identify how many taxa exist in this complex and how they can be distinguished morphologically. Data for 16 morphological characters were scored from 38 selected specimens from different geographical regions, including type specimens. Results from phenetic analyses, associated with observations in the field and of herbaria exemplars, support the recognition of five species, one with two varieties (A. alba, A. bromeliifolia var. bromeliifolia, A. bromeliifolia var. albobracteata, A. lamarchei, A. maasii and A. triangularis). Five previously recognized taxa are placed into synonymy: A. maculata and A. chlorophylla (both under A. lamarchei); A. pabstii (under A. alba); A. kautskyana (under A. triangularis); and A. bromeliifolia var. angustispica (under A. bromeliifolia var. bromeliifolia). This revision also includes a key to the species, descriptions, specimens examined, illustrations, photographs, distribution maps and information on conservation status.
