Geobiodiversity Research

Fundamental questions

How has the amazing diversity of life on Earth evolved, and what shapes diversity patterns through time and in space? The first question is at the centre of macroevolution, a discipline of biology and palaeontology that investigates speciation, extinction, and the evolution of species’ traits over long timescales (usually millions of years). The second question lies at the intersection of macroevolution with macroecology and biogeography, which study the (paleo-)ecology and the geographic distributions of species, higher taxa, and their traits on large spatial scales. Our research uses integrative approaches to address both questions and focuses on terrestrial vertebrates, in particular mammals and birds.

Integrative approaches

To understand the variation of diversity in species, higher taxa, and their traits across time and space, we investigate a broad range of topics, bringing together large-scale biogeographical, macroecological and macroevolutionary patterns to infer underlying mechanisms. We compile and synthesize large databases of the fossil record as well as on living taxa: data are gathered from preserved specimens in museum collections, public data resources, and literature mining, and data encompass species’ traits, geographic and stratigraphic occurrences, and phylogenetic relationships among organisms. Our research integrates methods across various disciplines, such as statistical and modelling tools commonly applied in paleontology and biology as well as macroecology and macroevolution.

Research goals

We are a diverse group of bio- and geoscientists and utilize interdisciplinary approaches to identify potential environmental drivers of biodiversity dynamics, such as climate change, mountain building, and increasing human impacts through the “Anthropocene”. Our goal is to learn from the past by studying the evolutionary history underlying present-day diversity patterns in relation to their abiotic, biotic, and anthropogenic drivers, in order to improve projections of future biodiversity in a world increasingly dominated by humans.

We review how geology and climate shape biodiversity in mountains, and demonstrate the effects of climate, topographic relief, heterogeneity of soil types, and erosion rates on the number of terrestrial vertebrate species occurring in mountain ranges across the world.

We show that climatic niches of migratory and sedentary bird species differ substantially from each other across a global dataset of ca. 500 species, indicating that the difference between the climatic niche in the breeding season and the climatic niche in the non-breeding season is typically larger for a migratory species than it is for a closely related sedentary species.

We find that paleoclimatic change did not drive the speed of change in climatic niches in a group of Old-World flycatchers (65 species of the bird family Muscicapidae) over the last 17 million years; however, cooler temperatures caused faster changes in temperature niche in the birds, but only when using one of two datasets of reconstructed paleoclimate.

Our study reveals a significant relationship of mammalian fossil diversity with primary production of biomass from plants. This relationship existed through the Neogene (23 to 1.8
million years ago), but fundamentally changed until the present day because many large mammals went extinct during or since the ice ages, and because humans remove a large proportion of primary production from natural systems today.

We reveal that combined effects of future climate and land-use change on the global species richness of vertebrates could be most severe when global warming is limited to 1.5 or 2 °C (Paris agreement), due to the massive expansion of bioenergy cropland for climate change mitigation.

We identify 11 terrestrial zoogeographic realms across the globe, which contrasts to the classic six realms defined by A. R. Wallace in the 19th century and used extensively since then. This contrast arises because our analyses combine data on not only species’ geographic distributions but also on their phylogenetic relationships (>21,000 species of non-marine amphibians, birds, and mammals).

We show that different ecological niche dimensions shape range size at individual vs. species level in terrestrial, non-flying mammals: while individual home range size is mainly shaped by diet niche breadth and body mass, species geographical range size is primarily related to habitat niche breadth.

We provide a conceptual framework for future interdisciplinary studies to test the effects of mountain building and climate change on biodiversity over long evolutionary timescales, and present a case study where we find that onset of surface uplift of the Central Anatolian Plateau ca. 11 million years ago coincided with a period of increased mammalian species turnover in the region.

We show that morphological traits can evolve differently in migratory vs. sedentary bird species, supporting different evolutionary selection regimes even in quite closely related species; e.g., migratory species across multiple lineages in five of eight tested groups consistently evolved more pointed wings than sedentary species, presumably because pointed wings cause a low energy consumption during long-distance flight.

Our conceptual framework for predicting the consequences of climate change on ecological interactions among species in communities argues that we need to combine climatic niche quantifications and projections with knowledge of ecological and morphological traits that govern species’ interactions as well as dispersal ability.
