Temporal Dynamics of a Neotropical Plant‐Hummingbird Interaction Network

Austral Ecology, Volume 50, Issue 7, July 2025.
Using an unprecedented sampling effort we evaluated network structure and dynamics of plant‐hummingbird interactions over 1 year in the Brazilian hyperdiverse Campos Rupestres. Network structure presented remarkable temporal change, showing that tropical communities can also be strongly influenced by climate.

Population Estimate and Spatial Distribution of Capybaras in Lake Paranoá, Brasília, Brazil

Biotropica, Volume 57, Issue 3, May 2025.
Understanding the dynamics of capybara populations living in urban environments is relevant, especially given the conflicts observed between the species and humans in these environments. Here, we investigated the hypothesis of overpopulation of the capybara in Lago Paranoá, a lake in a large neotropical city, Brasília, Brazil.

The response of neotropical dragonflies (Insecta: Odonata) to local and regional abiotic factors in small streams of the Amazon [PDF]

, 2019
Since the relative role of local and regional abiotic factors on the Odonata diversity in rainforest streams is still poorly understood, we evaluated the effects of these factors on adult Odonata (Insecta) from preserved and altered streams in the ...

How does the transformation of Cerrado vegetation into exotic pastures affect insect communities? A meta‐analysis Como a transformação da vegetação de Cerrado para pastagens exóticas afeta as comunidades de insetos? Uma meta‐análise

Insect Conservation and Diversity, Volume 18, Issue 2, Page 275-284, March 2025.
The structural components of the Cerrado are essential for conserving insect species richness, as conserved Cerrado habitats support higher insect species richness compared to exotic pastures Insect abundance is similar between conserved Cerrado and exotic pastures; therefore, synanthropic species may obscure the decline of sensitive insect populations

Description of the larva of Alampoides alychnus (Kirsch, 1873), the first known species with bioluminescent immatures in Euplinthini (Elateridae, Agrypninae)

Papéis Avulsos de Zoologia, 2013
Mature larva of Alampoides alychnus (Kirsch) is described and compared to known Pyrophorini immatures. Larvae were collected live in the soil of a region dominated by sugarcane plantation and gallery forest in Campo Novo dos Parecis, Mato Grosso, Brazil.

Geoclimatic drivers of diversification in the largest arid and semi‐arid environment of the Neotropics: Perspectives from phylogeography

Molecular Ecology, Volume 33, Issue 14, July 2024.
Abstract The South American Dry Diagonal, also called the Diagonal of Open Formations, is a large region of seasonally dry vegetation extending from northeastern Brazil to northern Argentina, comprising the Caatinga, Cerrado, and Chaco subregions. A growing body of phylogeography literature has determined that a complex history of climatic changes ...
