3D pollination biology using micro‐computed tomography and geometric morphometrics in Theobroma cacao

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Imaging technologies that capture three‐dimensional (3D) variation in floral morphology at micro‐ and nano‐resolutions are increasingly accessible. In herkogamous flowers, such as those of Theobroma cacao, structural barriers between anthers and stigmas represent bottlenecks that restrict pollinator size and access to reproductive ...

Thermoregulatory ability and mechanism do not differ consistently between neotropical and temperate butterflies

Global Change Biology, Volume 29, Issue 15, Page 4180-4192, August 2023., 2023
We studied how temperate and neotropical butterflies respond to temperature change. Neotropical butterflies were better at regulating their body temperature than temperate butterflies, mainly because at high air temperatures neotropical butterflies cooled themselves more.

Forest structure predicts species richness and functional diversity in Amazonian mixed‐species bird flocks

Biotropica, Volume 55, Issue 2, Page 467-479, March 2023., 2023
We show that vegetation structure can predict species richness and functional diversity in Amazonian mixed‐species flocks in primary and secondary forests. In addition, we show that secondary forest flocks retain a large percentage of the functional diversity exhibited by their primary forest counterparts. Abstract Secondary forest has the potential to

Phylogenetic and ecological correlates of pollen morphological diversity in a Neotropical rainforest

Biotropica, Volume 53, Issue 1, Page 74-85, January 2021., 2021
Abstract Morphology varies enormously across clades, and the morphology of a trait may reflect ecological function or the retention of ancestral features. We examine the tension between ecological and phylogenetic correlates of morphological diversity through a case study of pollen grains produced by angiosperms in Barro Colorado Island, Panama (BCI ...

Características morfológicas do sequestro pulmonar

Revista Portuguesa de Pneumologia, 2003
ABSTRACTThe pulmonary sequestration corresponds to pulmonary tissue intra or extra-lobar with systemic arterial nutrition and collateral bronchial ramification. It is unfrequent and the intra-lobar identification depends on the correct clinical signs and morphology.The correct study includes imagiologic identification of the systemic artery and ...
