A folha é um órgão de elevada plasticidade, sendo totalmente influenciada por fatores abióticos como a água, a temperatura e a luminosidade. Para plantas de regiões com disponibilidade hídrica temporalmente limitada, como ocorre na vegetação da Caatinga, os traços anatômicos foliares são considerados indicativos importantes de adaptabilidade. O pre...
Article
Plants in seasonally dry forests, such as the Caatinga in Brazil, possess adaptive characteristics to endure prolonged periods of drought and intense sunlight. However, few studies have delved into understanding, as proposed here, the convergence of these traits based on morphoanatomical features. Therefore, based on a systematic review, we investi...

Tradicionalmente, o fenômeno de convergência evolutiva pode ser descrito como o surgimento de características fenotípicas ou funcionais similares em espécies não relacionadas filogeneticamente, e que são fixadas por meio de seleção ou deriva, apesar de existir definições semelhantes ou terminologias relacionadas, como “convergência adaptativa”. Os...

A new species of Jacquemontia found in Carajás National Forest, Brazil, Jacquemontia ferricola sp. nov., is described for an area with a unique flora threatened by mining. We provide a diagnosis of the new species, morphological and anatomical descriptions, illustrations, scanning electron microscopy images, with comments on its distribution and co...
Article
Morphoanatomical studies can provide useful and relevant information to support taxonomic groupings. Jacquemontia evolvuloides shows great morphological variability, which has led to numerous taxonomic classifications. To determine if anatomical characters can be used to recognize operational taxonomic units within populations of that species, we a...

Article
Both comparative anatomical and morphometric approaches have been used for the taxonomic delimitations of species complexes. Some of the prevailing taxonomic problems in Convolvulaceae concern interspecific delimitations, as the family contains numerous species complexes that reflect its high levels of morphological variation. We propose here the d...

Daustinia montana (Moric.) Buril & A.R. Simões (Convolvulaceae) is currently classified as a highly polymorphic species with remarkable variations of leaf morphology, in terms of their sizes, shapes, margins, and indument. This foliar variability has led taxonomists to classify this taxon either as more than one species, with many varieties, or—mor...

Cenostigma microphyllum (Mart. ex G. Don) E. Gagnon and G. P. Lewis (Fabaceae) is a species endemic and widely distributed in the Brazilian dry tropical forest, ecologically important as a nurse species, favoring the growth of other plants, and maintaining mutualistic interactions with ants. Understanding plant responses to environmental variation...

Extrafloral nectaries (EFNs) are anti‐herbivory defense‐related glands. We measured morphological and anatomical EFN traits in Pityrocarpa moniliformis trees along a rainfall gradient in Caatinga dry forest. We observed a reduction in structural EFN traits as rainfall decreased. We conclude that this reduction is a cost‐saving strategy, probably me...

• Host plant selection by herbivores is driven by a complex array of cues, including leaf traits and previous leaf damage. Herbivore-associated cues to host selection at the plant and leaf scale aid understanding of mechanisms responsible for host preference that might translate into increased performance, as well as processes structuring herbivore...

A new species of Ipomoea , endemic to the Cerrado domain in Maranhão, Brazil, is described. Ipomoea maranhensis D.Santos & Buril, sp. nov. has been misidentified as I. burchellii Meisn. in several herbaria. Even though both species have oblong, pubescent leaves, they can be distinguished by morpho-anatomical characters. We present a diagnosis, comp...

Plant mines are structures with the form of a cavity caused by consumption of host plant tissue by the insect's miner larvae. Plant mines are more common in leaves, but in Cipocereus minensis, a species in which the leaves are modified spines, the miner activity is restricted to the stem. The aim of this paper was to document the morphological and...
