A morphometric study of the restinga ecotype of Anacardium occidentale (Anacardiaceae): wild coastal cashew populations from Piauí, Northeast Brazil

et al. 2019

The infraspecific taxonomy of wild Anacardium occidentale is little studied. We investigated whether wild populations on coastal dunes in Piauí, Brazil differed from non‐wild populations. Ten populations were sampled and twenty one morphological variables were measured. Variation within and between populations was investigated with univariate and multivariate statistics. Dune populations were mostly more similar to one another than to domesticated ones. There was significant correlation between inter‐population geographical distance and morphological dissimilarity. Classification methods showed 96.4% successful assignment to the dune category and 86% to 100% to dune populations individually, but dune and non‐dune populations overlap morphologically. Dune populations had shorter, broader leaves, shorter drupes and fewer secondary veins. Non‐dune coastal populations showed strongest similarity to dune populations. Populations distant from the coast were most divergent. The population from the cerrado region was most distinct, with thicker leaf blades and narrower petioles. The dune populations are recognised as the “restinga ecotype” of A. occidentale. Correlation of dissimilarity and distance may result from gene flow and/or non‐inherited environmental effects. Ecology and nomenclature (including the vernacular “cajuí”) of the restinga ecotype are reviewed. Further comparison of restinga populations is needed along the Brazilian coastline and with natural cerrado populations.

“…In southern Piauí, Castro et al. () cited A. occidentale , with the vernacular name “cajuí”, for the vegetation of Serra Vermelha, classified as “Floresta Estacional Semidecidual de Transição”, but since the authors did not include it in their sampling it must have been rare there.…”

“…In comparison with other surveys of restingas in Northeastern Brazil (Maranhão [Cabral- Freire and Monteiro 1993]; Ceará [Matias and Nunes 2001;Santos-Filho et al 2011;Castro et al 2012]; Rio Grande do Norte [Freire 1990;Almeida Jr. et al 2006;; Paraíba [Carvalho and Oliveira-Filho 1993;Oliveira-Filho and Carvalho 1993;Pontes and Barbosa 2008]; Pernambuco [Andrade-Lima 1951, 1960, 1979Leite and Andrade 2004;Sacramento et al 2007;Silva et al 2008;; Alagoas [Esteves 1980]; and Bahia [Pinto et al 1984, Viana et al 2006, Queiroz 2007, Queiroz et al 2012), 85.2% of the species listed for Piauí were also reported in other coastal areas of Northeastern Brazil, and the remaining 14.8% were recorded only in the restingas in Piauí (including Anacardium humile, Attalea speciosa, Bromelia karatas, Pilosocereus catingicola, Platonia insignis and Ruellia paniculata) (Table 1). Despite the fact that these species occur in many other restinga areas, specific localities tend to have their own floras due to environmental factors that influence species composition (Barros 2009), particularly under the influence of surrounding ecosystems.…”

Sandy coastal plain vegetation (Restinga) is composed of communities of plants that grow on Quaternary Neosols along the entire extension of the Brazilian coast. The state of Piauí has a coastal extension of 66 km and is entirely located in the semi-arid zone of Northeastern Brazil. This study catalogued the phanerogam species found along the coast of the state of Piauí, the data of which was compiled from surveys in online databases and literature, and herbarium collections. A total of 363 species distributed among 235 genera, and 74 families were identified. The families with the greatest number of species included Fabaceae (108 species), Euphorbiaceae (19), Amaranthaceae (13), Apocynaceae (12), Cyperaceae (12), Rubiaceae (12), Bignoniaceae (11), Malvaceae (11) and Poaceae (11) and represent over 57.6% of the species collected. Approximately 87% of the species were common to other restinga areas in Northeastern Brazil, and ca. 13% were restricted to the coast of the state of Piauí.

“…Segundo Castro et al (2009) diversidade de espécies refere-se à variedade de espécies de organismos vivos de uma determinada comunidade, habitat ou região. Neste trabalho foi usado o índice de diversidade de Shannon-Wiener, pois é o índice mais apropriado para as amostras aleatórias de espécies de uma comunidade ou subcomunidade de interesse, e é estimado a partir da seguinte equação: na floresta de Androstachys johansonii Prain, e em áreas de savana.…”

Resumo-O presente trabalho teve como objetivos caracterizar a composição e estrutura da floresta, dos ecossistemas de mopane, estimar os índices de crescimento e avaliar a sua distribuição diamétrica. Foram usados dados de parcelas permanentes estabelecidas em 2002 na região de Mabalane, Província de Gaza. Foi analisada a composição das espécies, sendo determinada a estrutura horizontal da floresta (abundância, dominância, frequência e índice de valor de importância) e e o incremento periódico anual em diâmetro. Os resultados mostraram a ocorrência de 15 espécies arbóreas pertencentes a onze famílias botânicas. A floresta é dominada pela espécie Colophospermum mopane (Benth.) J. Léonard (mopane), com uma abundância de 258,80 árvores por hectare, que corresponde a 85,8% do total dos indivíduos. O incremento periódico anual em diâmetro observado no período de 2003 a 2010 foi de 1,19 mm ano-1 , e verificou-se a distribuição diamétrica de J-Invertido. A floresta de mopane apresenta um crescimento lento e pouca diversidade de espécies, sendo importante a aplicação de intervenções silviculturais e estabelecer o plano de manejo de acordo com o ritmo de crescimento da espécie e estrutura horizontal e vertical dos remanescentes a serem manejados.
