New paper out! Happy to be the part of this study taking an overview of human legacies on island biodiversity! Led by Tom Matthews from Uni of Birmingham!

New paper out! 🖨️ Glad to be part of this study, out in Science Advances: "Emergent patterns of island biodiversity in the Anthropocene" www.science.org/doi/10.1126/... Much of what looks natural in island biodiversity is a legacy of human impacts going back millennia. See main findings 👇🧵 (1/8)

New paper out! R package *estar* to quantify all stability metrics. Important work from a project of Dr. Ludmilla Figueiredo, a PhD offspring of my lab, under Dr. Victoriia Radchuk postdoc mentoring!

Dr. Ludmilla Figueiredo from #iDiV, Sonia Kéfi, Paul J. Van den Brink, @jsarmentocabral.bsky.social, @cedricscherer.com ...nice collaboration together with our #IZW staff from D6! cran.r-project.org/web/packages...

I'm very proud that one of the discoverers, Ricardo Plácido, of this beautiful new species is a good friend of mine since our undergraduate studies back at UFRPE, in Recife! He was always carrying his Helmut Sick of Brazilian Birds and now he added one species to the list!

Huge News from the Western Amazon: it's the year 2025 and we are still describing entirely new, strikingly-distinctive large-bodied bird species! Behold Tinamus resonans sp. nov. the Slaty-masked Tinamou mapress.com/zt/article/v... #Ornithology @tetzoo.bsky.social 🪶

Photo montage of Tinamus resonans sp. nov., a new species of tinamou from the montane forests of the Serra do Divisor, western Amazonia, Brazil. The species is distinguished by a unique combination of plumage pattern, vocal repertoire, and ecological characteristics, including a conspicuous dark slate facial mask, vivid rufous-cinnamon underparts, and a uniform brownish-gray back. Its vocalizations are remarkable, consisting of long and powerful songs that echo strikingly across the steep montane slopes, producing a characteristic resonant effect. The species was documented exclusively at higher elevations within a transitional zone between submontane and stunted forests, where the understory is densely structured by root mats. A preliminary population estimate, based on field detections and spatial extrapolation, suggests approximately 2,106 individuals restricted to the Serra do Divisor massif. Although no immediate anthropogenic pressures were observed within its range, the species may be highly vulnerable to climate change and to proposed infrastructure projects that threaten the integrity of this federally protected region. The discovery of T. resonans highlights the biological uniqueness of the Serra do Divisor, reinforces its status as a center of montane endemism, and underscores the critical importance of maintaining its long-term conservation.
