Sad to hear of the passing of Robert Ricklefs - a giant of Ecology who simultaneously pushed forward big ideas at multiple biological levels yet took time for detailed natural history .. McGill does a nice job summarizing his impressive contributions 🌐🧪 dynamicecology.wordpress.com/2026/06/11/r...

Robert Ricklefs – in memoriam

Robert Ricklefs, a giant of ecology, passed away on Sunday. It is hard to overstate the extensive impact Bob had on the field. He was elected a member of the National Academy of Sciences in the US,…

During #SSB2026 @bruno-soares.bsky.social gave an excellent talk about the difficulty Global South researchers have describing new species because they often have to view types in US/European museums. Here is one solution we came up, published today: academic.oup.com/bioscience/a...

Recognizing the value of type localities can help democratize taxonomy for the Global South

Type localities, the geographic areas from which type specimens originate, play a central role in taxonomy (Azevedo-Santos et al. 2025, 2026). Despite thei

Brazil’s admirable little red-bellied toad—thumb-sized and critically endangered—once stopped a hydroelectric dam that threatened its only habitat. After the 2024 floods, researchers returned and found it still holding on, but climate change, plantations and trafficking risks loom.

The first amphibian to halt a hydroelectric dam now takes on the climate crisis

ARVOREZINHA, Rio Grande do Sul, Brazil — The admirable little red-bellied toad is the size of a thumb, but it has achieved giant feats: In 2014, it prevented the construction of a small hydroelectric…

We analyzed terrestrial #Ferns in 34 forest areas across Southern Brazil. Our goal: to check if current subtropical #AtlanticForest classifications match variations in species richness, diversity, and composition, while identifying key climate and soil drivers. 🌿🇧🇷 www.scielo.br/j/abb/a/c6vD...

The central role of soil in shaping terrestrial ferns’ assemblage composition, but not taxonomic diversity, in subtropical Atlantic forests

Abstract Understanding the uneven fern distribution is crucial for predicting future changes in...

Happy to share our latest article, which evaluates phylogenetic signal in plant phenology at species and assemblage scales. A new approach using phylogenetic eigenvectors. In a great partnership with @duarteldas.bsky.social #traits #climbingplants #phenology onlinelibrary.wiley.com/doi/10.1111/...

Contrasting Phylogenetic Signals in Flowering and Fruiting Phenology at Species and Assemblage Scales in a Climbing Plant Community

This study examined the phylogenetic conservatism of flowering and fruiting in 78 climbing plant species relative to environmental gradients in a South Brazilian forest. Although species-level analys....
