Transcriptionally active LTR retrotransposons in Eucalyptus genus are differentially expressed and insertionally polymorphic
Marcon, Helena Sanches; Domingues, Douglas Silva ; ; Borges, Rafael Junqueira ; Matioli, Fábio Filippi ; Fontes, Marcos Roberto de Mattos ; Marino, Celso Luis (BMC Plant Biology, 2015) [Artigo]
In Eucalyptus genus, studies on genome composition and transposable elements (TEs) are particularly scarce. Nearly half of the recently released Eucalyptus grandis genome is composed by retrotransposons and this data ... -
Worldwide evidence of a unimodal relationship between productivity and plant species richness
(Science (New York, N.Y.), 2015) [Artigo]The search for predictions of species diversity across environmental gradients has challenged ecologists for decades. The humped-back model (HBM) suggests that plant diversity peaks at intermediate productivity; at low ... -
Fenologia reprodutiva e distribuição espacial de Oeceoclades maculata (Lindl.) Lindl. (Orchidaceae) em Cerrado do município de Mogi Guaçu, São Paulo, Brasil
Souza-Leal, Thiago de; (Iheringia Serie Botanica, 2014) [Artigo]
Oeceoclades aculate (Lindl.) Lindl., an invasive orchid, was analyzed as to its reproductive phenology and spatial distribution, correlation between abundance of mature and immature individuals, and verifying these with ... -
Seedling structure in Asteraceae weedy species: considerations on the vasculature system
; ; ; Garcia de Almeida, Odair Jose; (Brazilian Journal Of Botany, 2014) [Artigo]
Seedling structure in Asteraceae weedy species: considerations on the vasculature system. The vasculature system of the seedling is of interest since it represents the first mature vascular coordination between shoot and ... -
Importance of anatomical leaf features for characterization of three species of Mapania (Mapanioideae, Cyperaceae) from the Amazon Forest, Brazil
Silva, Arthur de Lima; ; Coan, Alessandra Ike (Acta Amazonica, 2014) [Artigo]
Mapania belongs to Mapanioideae, a quite controversial subfamily in Cyperaceae due to the existence of unusual characters in both reproductive and vegetative organs. The genus is represented by seven species in Northern ... -
Functional and phylogenetic diversity of scattered trees in an agricultural landscape: Implications for conservation
Athayde, Eduardo Anversa; Cancian, Leonardo Farage ; ; Morellato, Leonor Patricia Cerdeira (Agriculture Ecosystems &environment, 2015) [Artigo]
Scattered trees are an important feature of the matrix of agricultural landscapes, but their role in biodiversity conservation is still controversial and largely unexplored. We aim to investigate the value of scattered ... -
Strong postzygotic isolation prevents introgression between two hybridizing Neotropical orchids, Epidendrum denticulatum and E-fulgens
Pinheiro, Fabio; ; ; ; ; ; Moraes, Ana Paula (Evolutionary Ecology, 2015) [Artigo]
Studies on hybrid zones are essential to understand the origin and evolution of reproductive barriers in plants. To achieve this goal, multidisciplinary approaches are often required to investigate the role of multiple ... -
Costs and benefits of reproducing under unfavorable conditions: an integrated view of ecological and physiological constraints in a cerrado shrub
; ; ; Morellato, Leonor Patricia C.; (Plant Ecology, 2015) [Artigo]
Disentangling the relative importance of biotic and abiotic constraints in plant reproduction is a major challenge in reproductive ecology. Here, we tested the 'resource limitation hypothesis'that predicts a high-level ... -
Anther wall development, microsporogenesis, and microgametogenesis in abolboda and orectanthe: contributions to the embryology of xyridaceae (poales)
Oriani, Aline; Scatena, Vera L. (International Journal Of Plant Sciences, 2015) [Artigo]
Premise of research. Xyridaceae includes two subfamilies with a total of five genera. Xyridoideae has only the single genus Xyris, and Abolbodoideae includes the remaining genera. The inter- and intrafamilial relationships ... -
Stay out (almost) all night: contrasting responses in flight activity among tropical moth assemblages
; Mendoza, I.; ; ; ; (Neotropical Entomology, 2015) [Artigo]
Variations in diel activity among hyperdiverse tropical communities of moths, despite representing a key component of niche partitioning between species, have barely been studied so far. Using light trapping from dawn to ... -
Development of ovule, fruit and seed of Xyris (Xyridaceae, Poales) and taxonomic considerations
Nardi, Kaire de Oliveira; Scatena, Vera Lucia ; Oriani, Aline (Botanical Journal Of The Linnean Society, 2015) [Artigo]
The development of the ovule, fruit and seed of Xyris spp. was studied to assess the embryological characteristics of potential taxonomic usefulness. All of the studied species have (1) orthotropous, bitegmic and tenuinucellate ... -
Deriving vegetation indices for phenology analysis using genetic programming
; ; ; Alberton, Bruna; Morellato, Leonor Patricia C. ; (Ecological Informatics, 2015) [Artigo]
