Fitossociologia de cerrado sensu stricto no município de Abaeté-MG Phytosociology of the cerrado sensu stricto in Abaeté, MG, Brazil

open access: yesRevista Árvore, 2003
O cerrado tem sido objeto de discussão de grupos temáticos que estudam a conservação de biodiversidade no Estado de Minas Gerais. São inúmeras as áreas de conservação com vegetação de cerrado das quais não se têm informações a respeito de sua composição ...

Byrsonima intermedia preparations inhibits trypsin and chymotrypsin activities from Aedes aegypti larval gut

open access: yesJournal of Medicinal Plants Research, 2014
This work describes the larvicidal activity of the ethanolic crude extract (EEB) as well as the hexanic (FH), chloroform (FCL), ethyl acetate (FAE) and remaining (FR) fractions obtained from Byrsonima intermedia leaves and bark against Aedes aegypti. Hexanic and remaining fractions from the leaves demonstrated larvicide activity against A.

Beyond Extrafloral Nectaries: Plant Traits as Drivers of Spider Occurrence in the Cerrado

open access: yesAustral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Patterns of predator occurrence arise from a mosaic of plant‐derived cues, yet most studies address these traits in isolation. Although extrafloral nectaries have received considerable attention, we lack a comprehensive view of how multiple plant traits jointly affect the diversity and abundance of spiders.

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1286-1298, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

Facilitative Interactions among Extrafloral Nectary-bearing Plants, Ants, and Neighboring Vegetation in the Brazilian Cerrado

open access: yesSociobiology
Herbivory is a key plant–insect interaction that can have a negative impact on plant development. Some plants have evolved indirect defenses by attracting protective ants through extrafloral nectaries (EFNs).

Complex interactions in ant–plant mutualisms: The role of multiple ant food resources in mediating plant defence, pollination and fitness in a tropical shrub

open access: yesEcological Entomology, Volume 50, Issue 6, Page 1137-1147, December 2025.
Our results show that ants reduced leaf herbivory on plants offering both EFN and trophobiotic insects. Although ants did not directly affect pollinator behaviour, leaf herbivory in plants hosting treehoppers indirectly influenced pollination by reducing both visit duration and frequency.

Variações morfológicas nas flores de Byrsonima intermedia (MALPIGHIACEAE) e seu impacto no valor adaptativo da espécie: polinização e produção de frutos [PDF]

open access: yes, 2021
For plants which rely on biological pollination, floral traits related to pollination can include tactile, olfactory and visual cues and color, shape and odor or combinations of these cues can be used to identify flowers as source of rewards. One of the components that attract pollinators is symmetry, used to discriminate flowers with different levels ...

Effects of Environmental Changes in Degraded Areas on the Establishment of Plant Communities in the Brazilian Cerrado

open access: yesInternational Journal of Forestry Research, Volume 2025, Issue 1, 2025.
Understanding the interrelationships between plant communities and soil attributes in gully erosion can make valuable contributions to strategies focused on the conservation and recovery of degraded areas. Thus, we aimed to evaluate how the composition and structure of different plant communities are affected by soil attributes in a degraded area by ...

Amplitude de nicho e similaridade no uso de recursos florais por abelhas eussociais em uma área de Cerrado

open access: yesBioscience Journal, 2007
A identificação das espécies de abelhas e suas relações com as plantas são importantes para conhecer os polinizadores e traçar estratégias de exploração racional de recursos naturais.
