Aim Estimate the Darwinian shortfall (i.e., the lack of knowledge about phylogenetic relationships) of bees worldwide, as well as identify their drivers. Location Global. Taxon Bees (Hymenoptera, Anthophila). Methods We built phylogenies for over 12,000 bee species, combining the most comprehensive phylogeny and an algorithm with random solutions to insert missing lineages. The Darwinian shortfall was quantified as the Phyloge...

Pathogenic fungi that cause rust adversely affect plants, including crops, affecting them differentially depending on the cultivar. This is the case of blackberry ( Rubus spp.), a member of Rosaceae, introduced in Brazil by Embrapa during the 1980s and 1990s. Given the advantageous nutritional properties of its fruits and the relatively low management costs associated with its cultivation, blackberry production has emerged as...

Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120 sites using active search and litter sifting. Native vegetation cover was quantified...

Neurodegenerative diseases (NDs) are characterized by progressive neuronal loss associated with excitotoxicity, oxidative stress, neuroinflammation, and impaired neuroplasticity. Fisetin, a naturally occurring flavonoid, has emerged as a potential neuroprotective compound due to its antioxidant and anti-inflammatory properties. In this study, we investigated the effects of fisetin in cellular models of glutamate-induced excito...

In its early years, the UN Decade on Ecosystem Restoration has mobilized unprecedented global commitments. Yet, measuring restoration success remains contested, particularly in megadiverse countries where the absence of standardized indicators and assessment protocols often leads to subjective decisions by environmental agencies. Here, we present a core set of leading indicators developed through a pioneering Brazil-led scienc...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

Understanding fish species distributions remains a key challenge in ecology, particularly in complex environments such as small Amazonian streams. These data are essential for developing and supporting effective management and conservation strategies, especially in highly diverse regions like the Amazon Basin, where substantial gaps in biodiversity knowledge persist. We assessed the structure and composition of fish assemblage...

Population-based preventive trials are rare in psychiatry, especially in an aging population, and the effects of potentially modifiable lifestyle risk factors such as diet on mental health outcomes are largely unexplored. This study aimed to estimate the effects of an anti-inflammatory diet on mental health outcomes in older adults and the potential effect of lifestyle modification. A preventive population-based target trial w...
