“…The allopatric species, A. manoel-felixii ( Figure 1b), was recently described by Almeida et al (2016) and is predominantly a violet glabrous shrub with quadrangular winged stems and opposite lance- Plants of Ameroglossum are self-compatible and also pollinated by hummingbirds (Wanderley, Lopes & Machado, et al, 2014), which have an ability to fly among adjacent inselbergs (~850 m). Seeds are dispersed by gravity, which makes dispersal to other inselbergs rare (Wanderley, Lopes, & Machado, 2014).…”

“…Ameroglossum occurs predominantly in the Borborema Plateau, north-eastern Brazil (Almeida et al, 2016). This plateau shows a highly heterogeneous landscape with steep gradients in elevation (~250-1200 m) and precipitation (~200-1000 mm/year) (Prado, .…”

“…Fisch., S. Vogel & A.V. Lopes, and the northern and narrow endemic A. manoel-felixii L.P. Felix & E.M. Almeida (Almeida et al, 2016;Wanderley, Almeida, & Felix, 2014;Wanderley, Lopes & Machado, et al, 2014) (Figure 1). Both species are exclusive to geographically isolated granitic rock outcrops scattered across the landscape, which are "terrestrial habitat islands" known as inselbergs (Porembski, 2007).…”

“…Ameroglossum pernambucense occurs in inselbergs from highland (1000-1200 m) forest enclaves of Atlantic rain forest that rise above the tropical dry forest of Caatinga, and A. manoel-felixii occurs in mid-elevation forest enclaves (500-600 m) and in surrounding areas of Caatinga. Leaf and flower size are among the main phenotypic differences between these species (Almeida et al, 2016) but some populations of Ameroglossum are taxonomically ambiguous because they exhibit leaf and flower sizes outside the strict taxonomic delimitation of A. pernambucense and A. manoel-felixii (Wanderley, Lopes & Machado, et al, 2014), which might be due to environmental isolation among inselbergs.…”

Aim In island‐like habitats, geographic isolation facilitates population and species divergence by constraining gene flow, while environmental isolation can enhance divergence. We tested the relative contribution of geographic and environmental isolation in genetic and phenotypic divergence within and between two species of the figwort Ameroglossum (Scrophulariaceae) inhabiting spatially isolated habitats, known as inselbergs. Location Borborema Plateau, north‐eastern Brazil. Methods Multivariate models of redundancy (RDAs) and partial redundancy analyses (pRDAs) were used to partition the geographic and climate components of genetic variation in 48 microsatellite alleles, and phenotypic variation in 11 leaf and flower traits. We also used linear mixed‐effect models (LMEs) to test independent associations of floral tube length variation among inselbergs with local pollinator phenotypes, climate and geography. In each approach, we analysed the data for each species separately and in pooled models for both species. Results RDAs revealed that genetic variation within and between the species of Ameroglossum was associated similarly with geography and climate. Phenotypic variation within A. manoel‐felixii and between species was also associated similarly with geography and climate but, within A. pernambucense, phenotype was more strongly associated with climate. Linear mixed‐effect models revealed that flower divergence in A. manoel‐felixii was associated only with the bill length of local hummingbirds, whereas floral variation in A. pernambucense was associated with geography, bill length and climate. Only climate was associated with flower divergence between species. Main conclusions Genetic and phenotypic variation in Ameroglossum are associated with geographic and environmental isolation. These findings indicate a significant role of ecological factors shaping plant divergence among inselbergs, irrespective of their spatial distances.

“…Orchidaceae, Araceae, Bromeliaceae, bem como Pteridófitas, muitas delas raras e de importância ornamental (Safford e Martinelli, 2000). O gênero Ameroglossum, endêmico de inselbergues da região Nordeste (Fischer et al, 1999), por exemplo, possui apenas duas espécies conhecidas, uma delas descrita recentemente (Almeida et al, 2016). Por isso, inselbergues são considerados áreas importantes para a conservação e prioritárias para a criação de futuras unidades de conservação.…”

A Serra do Jatobá constitui um monólito localizado a 10 km do Município de Serra Branca. Destaca-se do relevo suavemente ondulado da região, com uma cobertura vegetal composta principalmente por plantas rupícolas. Neste trabalho foi realizado um levantamento florístico, paisagístico e dos usos atuais e potenciais da flora desse local. Também foi levantada a ocorrência de espécies raras e seu potencial para uso como planta ornamental. O afloramento apresenta diferentes microambientes, destacando-se sulcos, fendas e tanques ou caldeirões, todos resultantes da atividade erosiva, caracterizados pela presença de espécies exclusivas. Foi levantado um total de 41 espécies distribuídas por 33 gêneros e 20 famílias localmente exclusivas. A análise da paisagem e do componente florístico confirmou o potencial deste afloramento para uso em atividades de turismo ecológico e de aventura. Das 41 espécies levantadas, 21 têm diversas utilizações atuais e potenciais referidas pela literatura, especialmente em revistas de medicina, farmácia, etnobotânica e fitoquímica. Dentre estas, 11 espécies foram referidas como medicinais seguidas por outros usos, forragem e tóxicas. Mandevilla dardanoi foi a única espécie rara do afloramento, sendo conhecida anteriormente apenas para o Estado de Pernambuco. Ophioglossum aff. nudicaule é possivelmente uma nova espécie e, juntamente com a ocorrência de uma espécie rara, sugere que a Serra do Jatobá deve ser considerada área prioritária para a conservação. Além disto, o turismo ecológico poderá ser uma alternativa viável que contribuirá para a manutenção da biodiversidade, podendo ser uma nova alternativa econômica para as comunidades do entorno.
