The making of pure quartzose sand in continental interiors: Paraná River (Brazil and Argentina)

Sedimentology, EarlyView.
ABSTRACT As part of a comprehensive project on sedimentary processes in South America, this study focuses on sediment generation in the intracratonic Paraná Basin and monitors the evolution of sand composition along the Paraná River from central Brazil to the Río de la Plata estuary in Argentina.

A climate‐sensitive tropical urbanism under extreme heat†

Singapore Journal of Tropical Geography, EarlyView.
Tropical urban dwellers face twin climate challenges that impinge on their quality of life: climate overheating and the urban heat island (UHI). The latter superimposed on the former to lead to high levels of thermal discomfort, carbon and energy consequences.

The Role of Gene Flow in the Diversification of the Monkey Treefrog Complex Across the South American Dry Diagonal

Zoologica Scripta, EarlyView.
ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,

What are the vector species of the Oropouche virus?

Pest Management Science, Volume 82, Issue 4, Page 2785-2793, April 2026.
Here, we review the timeline of Oropouche virus (OROV) detection in various hematophagous Diptera, from 1955 to date, including mosquitoes and midges. All vector competence experiments also are described. The results suggest that Culicoides are the primary vectors.

Revealing patterns of endemism in the transatlantic family Chelodesmidae (Polydesmida: Diplopoda)

Cladistics, Volume 42, Issue 2, Page 159-171, April 2026.
Abstract With fossil records dating back to the Silurian/Late Ordovician, millipedes stand out as one of the earliest terrestrial animal groups. Their limited vagility and high endemism make them valuable tools for formulating and testing biogeographic hypotheses, including those related to macro‐vicariance events.

Extending the distribution of Latrodectus corallinus Abalos, 1980 (Araneae: Theridiidae) in South America: first record for Brazil

Revista Chilena de Entomología
The widow spider Latrodectus corallinus Abalos, 1980, a species reported previously only for Argentina, was recorded in the central-western region of Brazil, associated with sandstone caves in São José do Rio Claro, in the State of Mato Grosso, and in ...

Seasonality as a structuring factor of the dung beetle community in burned neotropical savannas

Ecological Entomology, Volume 51, Issue 2, Page 336-345, April 2026.
We tested the effects of fire, vegetation cover and seasonality on dung beetle communities, focusing on species richness, composition and co‐occurrence patterns in savannas. Fire did not affect species richness. However, seasonality was the dominant factor influencing species composition, followed by fire and vegetation cover.

Abiotic drivers of co‐occurrence and diversity patterns of Calopterygidae species in Amazonian protected freshwaters

Ecological Entomology, Volume 51, Issue 2, Page 235-249, April 2026.
Species co‐occurrences rely on their ability to explore similar or distinct available resources, and possible niche overlap can prevent their presence and establishment in a given site Damselflies of the Calopterygidae family demonstrated negative co‐occurrences in streams inside and outside PAs, highlighting that their ecological similarity is ...

The role of habitat simplification and seasonality in shaping interactions between ants, plants and herbivores in a neotropical savanna

Ecological Entomology, Volume 51, Issue 2, Page 381-394, April 2026.
We evaluated how chronic anthropogenic disturbances (CAD) and seasonal variation influence interactions between ants and plants with extrafloral nectaries (EFN's), with emphasis on the responses of ants, herbivores, and plants. Ant and herbivore diversity remained stable across seasons in the preserved cerrado, whereas the pasture had higher ant ...
