Producing a Red List of Ecosystems for the Brazilian Cerrado

Conservation Science and Practice, EarlyView.
Land clearance is a key driver of biodiversity loss. This is a particular issue in the Brazilian Cerrado, the world's most biodiverse savanna biome and a region experiencing the rapid expansion of agriculture. By using the Red List of Ecosystems as an international standard, we provide the first globally comparable analysis of the state of the Cerrado,

Social bees can enhance the persistence of plant–bee interactions during seasonal changes in seasonally dry tropical forests

Ecological Entomology, EarlyView.
Social bees, especially Meliponini, formed a persistent core that maintained plant–bee interactions across both dry and green seasons in the Caatinga. Persistence was not linked to broader diets; social bees used fewer plant species, despite availability, indicating selective tracking of temporally concentrated floral resources.

Beyond the specimen: rethinking ornithological collecting in a changing world

Ibis, EarlyView.
Natural history collections underpin a wide range of ornithological research, yet the context in which they operate is rapidly changing. Advances in genomics, digitization and analytical approaches are transforming what can be learned from specimens, while accelerating environmental change is increasing the need for temporally explicit, integrative ...

Incorporating light pollution into projections of the future distribution of Aspisoma sticticum Gemminger, 1870 under climate change in South America

Insect Conservation and Diversity, EarlyView.
Climate‐only models predict severe habitat contractions by 2100, especially in the Amazon, Cerrado and Caatinga, while southern and coastal Atlantic Forest areas remain refugial. Including artificial light at night increased projected stability and apparent suitability gains, especially in central and eastern South America.

When troglobites set the rules: How cave‐restricted species shape community responses in the richest tropical subterranean hotspot

Insect Conservation and Diversity, EarlyView.
Troglobites strongly shape community responses to environmental gradients, weakening patterns when excluded from analysis. High beta diversity dominated by species replacement, driven by distance from entrance and microclimatic factors. Resource availability and microclimate stability are key to maintaining this subterranean biodiversity hotspot ...

Entomological surveillance of Trypanosoma cruzi vectors in Rio Grande do Norte, Brazil

Medical and Veterinary Entomology, EarlyView.
Discontinuous entomological surveillance and persistent infestation by triatomines highlight the risk of Trypanosoma cruzi transmission. The diversity of triatomine species in the peridomicile shows the potential for colonization into the home. The wide distribution of Triatoma brasiliensis and Triatoma pseudomaculata accompanies high rates of ...

Nesting Substrate Characteristics of Partamona seridoensis Pedro & Camargo (Hymenoptera: Apidae) in Areas of Dry Forest in Brazil

Sociobiology, 2017
For the first time the association between Partamona seridoensis and Constrictotermes cyphergaster is described. Partamona seridoensis occurs in xeric areas of Northeastern Brazil, and it is a termitophile species as its nests are built in active and ...

A dual pollination strategy combining perfume attraction and food deception in Galeandra blanchetii E.S. Rand (Orchidaceae)

Plant Biology, EarlyView.
Galeandra blanchetii exhibits a dual‐attraction strategy: male euglossine bees are lured by floral scents as a resource, while both sexes are deceived by non‐existent nectar. Pollination only occurs when bees enter the spur to search for nectar, highlighting an evolutionary transition towards the perfume flower syndrome in Catasetinae.
