“…This selective pattern was previously recorded for miners of grasses (Scheirs et al 1997;. Interestingly, grasses are similar to bromeliads at a general nutritional, chemical, mechanical and anatomical level (Almeida et al 2009;Tomlinson 1969). Leaves of grasses have low concentrations of nutrient and active secondary compounds, as well as presenting mechanical defences such as a parallel array of tough vascular bundles surrounded by fibres and high levels of silica (Bernays & Barbehenn 1987;Tscharntke & Greiler 1995;Vieira & Mantovani 1995).…”

Recebido em 15/03/2011. Aceito em 23/07/2012 RESUMO (Efeito da herbivoria foliar na bromélia Aechmea blanchetiana: estudo sobre o padrão seletivo de forrageamento do inseto raspador Acentroptera pulchella). O raspador Acentroptera pulchella (Chrysomelidae, Hispinae) foi observado se alimentando de folhas de Aechmea blanchetiana (Bromeliaceae), mas não de forma indiscriminada. Este inseto aparentemente concentra seu ataque na metade superior das folhas intermediárias do tanque da bromélia. A fim de caracterizar a potencial influência de estratégias defensivas contra herbivoria no padrão alimentar intra-específico de A. pulchella, sobre folhas da bromélia A. blanchetiana, nós: i) quantificamos a aparente preferência intra-específica deste padrão alimentar, ii) comparamos folhas e partes distintas em relação à estratégias morfo-fisiológicas, mecânicas, nutricionais e químicas contra herbivoria e iii) avaliamos se algumas ou todas estas estratégias defensivas ajudariam a explicar o padrão alimentar observado. O raspador A. pulchella atacada preferencialmente a metade superior de folhas intermediárias e adultas de A. blanchetiana, mas não a metade inferior das mesmas folhas, as quais são mais resistentes à perfuração, mais espessas e apresentam menor teor de nitrogênio do que a parte superior. Ao mesmo tempo, porém, folhas jovens e tenras não foram atacadas. As metades atacadas também apresentaram maior teor de fenóis totais em comparação as não atacadas, indicando que os fenóis não atuam defensivamente neste caso. Outras estratégias morfo-fisiológicas e químicas contra herbivoria não variaram entre as partes ou folhas aqui avaliadas. O herbívoro estudado se alimenta preferencialmente de partes das folhas com maior teor de nitrogênio, evitando ao mesmo tempo outras com maior resistência à perfuração. Concluímos que o raspador A. pulchella apresenta claro padrão seletivo de forrageamento, onde o mesmo é direcionado mais por benefícios nutricionais do que estritamente por estratégias mecânicas ou químicas contra herbivoria.

The scraper Acentroptera pulchella (Chrysomelidae, Hispinae) feeds on the leaves of Aechmea blanchetiana (Bromeliaceae), but not indiscriminately. This insect apparently concentrates its attack on the apical region of the intermediate leaves from the bromeliad tank. To characterise the potential influence of leaf defensive strategies on the intraspecific feeding pattern of A. pulchella on the leaves of the bromeliad A. blanchetiana, we quantified the apparent intraspecific preference of this feeding pattern; compared distinct leaves and portions in relation to morpho-physiological, mechanical, nutritional and chemical anti-herbivore strategies; and investigated whether some or all these defensive strategies help explain the observed feeding pattern. A. pulchella preferentially attacked the mid-upper po...

Quesnelia is a genus of the subfamily Bromelioideae (Bromeliaceae) with 20 species endemic to Brazil occurring from the south portion of the state of Bahia to the northern portion of the state of Santa Catarina. Quesnelia is subdivided into two subgenera: Quesnelia subg. Quesnelia and Quesnelia subg. Billbergiopsis. The purpose of this work was to conduct a taxonomic study of Quesnelia species from Paraná state (southern Brazil) along with morphological and taxonomic analysis of in vivo material and specimens in herbaria collections. Three taxa were found: Quesnelia humilis, Q. imbricata and Q. testudo. This work presents identification keys, morphological descriptions, geographical distribution, comments, illustrations and the conservation status of the studied taxa. Key words: flora, monocotyledons, Southern Brazil. ResumoQuesnelia pertence à subfamília Bromelioideae (Bromeliaceae) com 20 espécies, endêmicas do Brasil ocorrendo desde o sul da Bahia até o norte de Santa Catarina, enquadradas em dois subgêneros: Quesnelia subg. Quesnelia e Quesnelia subg. Billbergiopsis. Um estudo taxonômico do gênero para o Paraná foi realizado, consistindo de pesquisa bibliográfica, estudo morfológico e taxonômico de material in vivo e de exemplares das coleções de diversos herbários. São reconhecidos três táxons: Quesnelia humilis, Q. imbricata e Q. testudo. Chaves de identificação, descrições morfológicas, distribuição geográfica, comentários, ilustrações e o status de conservação dos táxons estudados são apresentados.

“…The first group of studies used different data sets, with a focus on relationships among the subfamilies (Ranker et al 1990;Terry et al 1997a;Horres et al 2000;Givnish et al 2007Givnish et al , 2011, within the subfamilies (Terry et al 1997b;Crayn et al 2000;Barfuss et al 2005;Horres et al 2007;Schulte et al 2009;Sass & Specht 2010) or within genera and subgenera (Rex et al 2007;Sousa et al 2007;Chew et al 2010;Versieux et al 2012). With the exception of the study of Gilmartin & Brown (1987), which questioned the monophyly of the family, its possible sistergroup, and the relationships among the subfamilies, phylogenetic analysis based on morphological data have focused on subfamilies (Varadarajan & Gilmartin 1988), tribes (Forzza 2001), genera (Gilmartin et al 1989;Leme 2000;Faria et al 2004;Hornung-Leoni & Sosa 2008;Almeida et al 2009;Monteiro 2009, Gomes-da-Silva et al 2012Saraiva 2013) or subgenera (Gilmartin & Brown 1986;Beaman & Judd 1996;Tardivo 2002;Sousa 2004) in all subfamilies. Combined morphological and molecular data were also used to improve the resolution of the analysis (Faria 2006;Sousa et al 2007;Aguirre-Santoro 2009;Gomes-da-Silva 2013).…”

Vriesea, with about 280 species distributed in two sections, Vriesea and Xiphion, is recognized as polyphyletic. We provide the cladistic analysis based on morphological data, with emphasis on species from eastern Brazil, its main center of diversity, which emerged as a monophyletic group in previous molecular and combined analysis. The data matrix contained information of 60 species of Vriesea, and two of Alcantarea, for a total of 62 terminal taxa and 66 characters. The analysis produced one tree with 652 steps. The classic infrageneric division of the sections was not corroborated. Characters traditionally used to separate the two sections supported clades containing species from both sections. Morphologically related monophyletic groups were recognized. Some characters have been highlighted as potentially important in the circumscription of small groups of species and have not yet been much used in the systematics of Vriesea.
