Glad to share our new study at @natcomms.nature.com which resulted from several workshops on the early warning signs of mass extinctions and coordination of macroevolutionary vulnerability and the states of carbon cycle and temperatures. www.nature.com/articles/s41... 🧪⚒️ #Geology #Paleobio #EvoBio

🧵 Excited to share my final PhD paper in Ecology Letters! A classic question in ecology is why some clades contain more species in local assemblages than others. We argue that part of the answer lies in the timing of speciation itself. doi.org/10.1111/ele....
Megafaunal extinctions, including saber-toothed cats and ground sloths, simplified food webs in the American tropics, which now feature smaller predators and fewer prey species per predator, compared with tropical food webs in Africa and Asia. In PNAS: https://ow.ly/o1mi50YV4M3
Our recent paper on human-induced trait shifts and predator–prey interactions is on the cover of the May issue of Trends in Ecology & Evolution 😭😵💫 The paper is available open access here -> www.cell.com/trends/ecolo...
New paper out! doi.org/10.1073/pnas... We examined how historical legacies of evolution history, environmental dynamics, and past species losses have shaped today's mammal food webs 🐅🐆🦁 🦌🦓🐗across the globe. #MammalFoodweb #DietaryNiche #Extinction #MacroEcoEvo #EcologicalNetwork
Giants that vanished 10,000 years ago triggered ripple effects that are still felt today, and here’s where
Between 50,000 and 10,000 years ago, many of the world’s largest mammals disappeared. Picture creatures like saber-toothed cats with 7-inch fangs and elephant-sized sloths. A new study reveals h...

📣 New paper out in @plosbiology.org What drives global patterns of species richness? 🌍 Using a unified framework across 129 tetrapod clades 🐸🦎🐦🐘, we find: 👉 Productivity-driven equilibrium dynamics largely explain biodiversity patterns ⚖️🌱 doi.org/10.1371/jour... #Macroecology #Biogeography
Excited to be part of this collaborative effort tackling a longstanding question: how does productivity shape community assembly from simple species co-occurrence to complex trophic interactions? Check out what we discover! #foodweb #communityassembly #africa #plantproductivity #macroecology
Food Web Similarity Increases With Productivity Similarity at a Continental Scale
Here, we test how plant productivity and anthropogenic fragmentation predict the pairwise similarity of food web networks within and among regions for 127 protected areas spanning deserts to rainfore...

The "birds that don't exist" paper is out in Ecology Letters! 🍻 We found a viable body form that has never evolved in a big clade of songbirds, and tested a series of hypotheses to figure out why. onlinelibrary.wiley.com/doi/10.1111/...
Birds That Don't Exist: Niche Pre‐Emption as a Constraint on Morphological Evolution in the Passeroidea
We use topological data analysis to reveal a persistent morphological gap in a major group of songbirds (superfamily Passeroidea). The gap remained unoccupied for millions of years, even though nearb...

My paper just came out! Urban parks and green spaces are widely known for their environmental benefits in mitigating climate change. However, my study reveals that managements can interrupt the natural connection between plants, soil organisms, and microbes that keep soils healthy and carbon-rich.
Management matters: homogenized plant–soil linkages constrain carbon cycling in urban green spaces - Urban Ecosystems
Urban Ecosystems - Urban green spaces (UGSs) have been promoted as nature-based solutions for climate change mitigation and biodiversity conservation. Most UGS planning and studies use vegetation...

Which paleoclimate dataset do you use for your research? In my latest research, I compared temperature estimates from five well-known paleoclimate datasets to proxy data and found that inter-dataset variability can strongly affect temperature-delimited reconstructions. 🧵 ➡️ doi.org/10.21425/fob...

Lab’s publication came out! Bye-bye butterflies? Insects are in 'precipitous decline' in Midwest. #ZipkinLab #Ecology #QuantitativeEcology #Conservation
Some butterfly species have declined in the Midwest; none has increased, MSU study finds
In the last three decades of data from butterfly counts in the Midwest, none of the butterfly species increased in population. More than 40% declined in number.

First postdoc paper just dropped! Using 50 years of Breeding Bird Survey data, we found that the unexpected functional shifts of bird communities in North America do not track species-level expectations, and these unexpected shifts can be explained by just 5% of “hyper-dominant” species.
