An Ecological Comparison of Floristic Composition in Seasonal Semideciduous Forest in Southeast Brazil: Implications for Conservation

International Journal of Forestry Research, Volume 2012, Issue 1, 2012., 2012
We examined floristic patterns of ten seasonal semideciduous forest sites in southeastern Brazil and conducted a central sampling of one hectare for each site, where we took samples and identified all individual living trees with DBH (diameter at breast height, 1.30 m) ≥4.8 cm. Arboreal flora totaled 242 species, 163 genera, and 58 families.

Shedding Light on Shining Leaf Chafers: Rutelinae MacLeay, 1819 (Coleoptera, Scarabaeoidea, Scarabaeidae) as a Neglected Group of Pollinators

Journal of Applied Entomology, Volume 149, Issue 10, Page 1584-1599, December 2025.
ABSTRACT The interactions between insects and angiosperms date back to millions of years ago. Among the groups of pollinating animals, it is estimated that insects are responsible for pollinating more than 70% of angiosperms. Coleoptera is one of the most studied insect groups for pollination.

Foraging of Scaptotrigona aff. depilis (Hymenoptera, Apidae) in an Urbanized Area: Seasonality in Resource Availability and Visited Plants

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
The floral sources used by bees can be identified by analyzing pollen grains obtained from their bodies, feces, brood cells, or storage pots in the nests. In addition to data on resource availability, this information enables the investigation on the selection of food resource by bees. We assessed the foraging patterns of Scaptotrigona aff.

Isolated Trees in a Fragmented Tropical Landscape: A View Through the Soil Seed Bank

Biotropica, Volume 57, Issue 5, September 2025.
Here, we investigated patterns of plant species diversity, abundance, and composition in the soil seed banks of cattle pastures, under fleshy‐fruited, and nonfleshy‐fruited trees within pastures, and in secondary forest patches at ten study sites in Brazil.
