1. Past and future climate-driven extinction resilience and associated traits

Understanding and predicting how species and communities will respond to future climate changes have become one of the major 21st-century scientific pursuits, uniting ecologists, evolutionary biologists, and conservationists. My research focuses on identifying key traits that allowed species to survive past extinction events and to live in present-day harsh environments. This will produce more informative predictive models and highlight target groups and regions that host the most vulnerable taxa to human-induced climate change.

2. Drivers of mammalian diversification in the Qinghai-Tibetan biodiversity hotspots

Asia is one of the richest continents in species diversity, including fourteen of the global biodiversity hotspots. Large part of its biodiversity is closely linked to the Cenozoic geodiversity, especially the active mountain building resulting in the formation of the Qinghai-Tibetan plateau and the surrounding mountains (Himalayas, and Hengduan). Their orogeny has drastically changed the surrounding climate and vegetation and shaped the present-day biodiversity in Asia. In this project, we will assess the tempo and mode of range evolution of Asian mammals to infer how and when the diversity across regions and mountain hotspots assembled. We are particularly interested in testing whether periods of intense tectonism, such as orogeny and continental collisions, and marked climatic changes are related to peaks in diversification and major dispersal events shaping the present-day regional mammal diversity in Asia.

3. Phenotypic evolution in high-altitude mammals

Species adapted to harsh environments often display multilevel, interdependent modifications—from genes to life-history traits—allowing them to cope with physical and biotic selection. Living at high altitudes is a great challenge for most endothermic animals given the low oxygen levels, cold temperatures, and high solar radiation. Notably, high elevations combine some of the stressful conditions present in subterranean (chronic hypoxia) and desert (reduced food supply, short growing season, high predator exposure) environments. While numerous studies have investigated genetic pathways and physiological changes among high-elevation organisms, only a few have assessed adaptive responses in traits associated with resource use (i.e. beaks, jaws, skulls) among montane organisms. In this project, we explore skull adaptations to altitude, seeking overall phenotypic patterns across groups of mammals.

4. Elevation patterns of small mammal communities

Species distributed along mountain slopes, which face conspicuous climatic and steep vegetation changes on a short geographic scale, are of particular interest for assessing how their community are structured. In particular, as altitude increases, steep environmental changes promote spatially dynamic biotic and abiotic interactions. Such mixed effects of contrasting climatic variables on a short scale reflect marked heterogeneous vegetation zonation along mountain slopes, in some cases mirroring tropical–temperate forest transitions. In collaboration with researchers from the Institute of Zoology, Chinese Academy of Sciences, our projects focused on elevation patterns of small mammal communities across China.

5. Systematics of Neotropical mammals

This is a broad and long-term project studying the diversity of mammals from the Neotropical region in collaboration with diverse researchers from Brazil and the United States. Largely based on museum specimens, we explore intra- and interpopulation variation to define species and geographic limits and assess their evolutionary history. My main study groups include armadillos, cats of the genus Leopardus, Neotropical porcupines (genus Coendou), and bats. Our taxonomic studies incorporate a wide range of morphology-based and molecular-based methods in an integrative way.  Recently, we have also added niche models and ecological segregation as new lines of evidence to better set species limits.

6. Revealing the Caatinga mammal diversity

The Caatinga, the largest tropical dry forest in South America, is one of the poorly known biomes in Brazil. Since 2010, I have been studying the community structure, diversity, ecological aspects, and conservation challenges of mammals from that region, especially focusing on bats and armadillos.
