Leaf Venation of Brazilian Species of Cryptocarya R. Br. (Lauraceae)
(2021-06-01)
With the aim of recognizing and identifying both fertile and sterile specimens of Cryptocarya from Brazil, we analyzed the leaf venation pattern of 14 taxa, 6 of them being described and illustrated for the first time. A ...
Relationship between mandible morphology and leaf preference in leaf-cutting ants (Hymenoptera: Formicidae)
(Soc Colombiana Entomologia-socolen, 2015-07-01)
Morphological differences among mandibles of grass and leaf-cutting ant species were examined. Specifically, we compared morphometric measurements from mandibles of four species (Atta laevigata, A. bisphaerica, Acromyrmex ...
Expanding our understanding of leaf functional syndromes in savanna systems: the role of plant growth form
(2017-04-01)
The assessment of leaf strategies has been a common theme in ecology, especially where multiple sources of environmental constraints (fire, seasonal drought, nutrient-poor soils) impose a strong selection pressure towards ...
Morphological patterns and community organization in leaf-litter ant assemblages
(ECOLOGICAL SOC AMER, 2010)
We present a new approach to determine the number and composition of guilds, using the hyperdiverse leaf-litter ant fauna as a model, based on appropriate morphological variables and species co-occurrence null models to ...
Leaf venation of Ocotea species (Lauraceae) from Bahia, Brazil
(2021-01-01)
With the aim of recognizing and identifying both fertile and sterile specimens of Ocotea from the Brazilian state of Bahia, we analyzed the leaf venation pattern of 55 species, 21 of them being described and illustrated ...

(2021-03-01)
With the aim of recognizing and identifying both fertile and sterile specimens of Ocotea from the Reserva Natural Vale, Linhares, we analyzed the leaf venation pattern of 31 species, 13 of them being described and illustrated ...
Leaf venation of Lauraceae species (excluding Ocotea) from the Reserva Natural Vale, Linhares, Espírito Santo, Brazil
(2021-09-01)
With the aim of recognizing and identifying both fertile and sterile specimens of Lauraceae from the Reserva Natural Vale, Linhares, we analyzed the leaf venation pattern of 20 species belonging to 11 genera. The venation ...
Leaf venation of Lauraceae species (excluding Ocotea) from Bahia, Brazil
(2021-06-01)
With the aim of recognizing and identifying both fertile and sterile specimens of Lauraceae from the Brazilian state of Bahia, we analyzed the leaf venation pattern of 56 species belonging to 14 genera (excluding Ocotea), ...
TAXONOMIC USE OF LEAF ANATOMICAL CHARACTERS IN THE GENUS SIMAROUBA-AUBLET (SIMAROUBACEAE)

Photosynthetic responses of understory savanna plants: Implications for plant persistence in savannas under tree encroachment
(2018-03-01)
Savannas are ecosystems where plants are expected to have leaf-level adaptations conferring tolerance to high irradiances, which characterizes this type of open canopy vegetation. The neotropical savannas of Brazil (Cerrado) ...
