Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

Biological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

The Role of Environmental Factors on Visual Communication in Neotropical Anurans

Global Ecology and Biogeography, Volume 35, Issue 2, February 2026.
ABSTRACT Aim Visual signals are a widespread behavioural attribute of communication among vertebrates, often employed during intrasexual competition or mate attraction, ultimately influencing reproductive success. However, the environmental factors driving visual signal evolution remain poorly understood.

How Management Practices Shape the “Local Habitat Signature” That Modulates Bird Communities in Urban Green Spaces

Biotropica, Volume 58, Issue 1, January 2026.
Local scale factors, not just the broad urban gradient, are the key drivers of urban bird communities. Our multi‐scale study found that specific management practices, such as managing leaf litter depth or the presence of unmanaged tall grass, explained the largest portion of variation in bird composition.

The Hidden Diptera Diversity in Aristolochia Trap‐Flowers: Revealing the Identity of Pollinators Through Taxonomic Knowledge

Journal of Applied Entomology, Volume 149, Issue 10, Page 1502-1512, December 2025.
ABSTRACT Although Diptera is one of the most diverse insect orders with a high potential for pollinating plants, it remains poorly studied and neglected. This is partly due to limited taxonomic efforts in species identification. For instance, despite being primary pollinators of trap flowers, species‐level identification in these systems remains scarce.

Effects of Long‐Term Nutrient Addition on Leaf Metabolites, Herbivory, and Mycorrhizal Spores Associated With a Savannah Woody Species

Austral Ecology, Volume 50, Issue 11, November 2025.
ABSTRACT Given the importance of soil conditions for ecosystem functioning, fertilisation experiments are a valuable tool for assessing how systems respond to changes in soil properties. However, the effects of changes in nutrient availability on multitrophic interactions in savannah ecosystems of the Brazilian Cerrado are still scarce. We investigated
