Professional career

Bert is currently working at the National Museum of Natural History of the Smithsonian Institution in Washington DC (October 2011 - March 2014) in the departments of Paleobiology (with Gene Hunt) and Invertebrate Zoology (with Ellen Strong). He is studying the diversification of viviparid gastropods in an ongoing evolutionary radiation in long-lived Lake Malawi integrating both paleontological and neontological perspectives. He is also comparing patterns of morphological disparity with molecular diversity in African viviparids on a continent-wide scale and is conducting experimental work on the radiating gastropods of Lake Malawi at the Research Unit Palaeontology (UGent).

Context and outlines of the current project

Background. A central question in the theory of evolution is how, through the process of speciation, new species actually develop. Which combinations of genetic, ecological and environmental factors lead to speciation and determine the speed and intensity of the process? The main scientific disciplines addressing speciation are paleontology, evolutionary ecology and molecular biology. Most studies in paleontology document morphological changes in biota over periods of hundreds of thousands of years, using fossil evidence and genealogical inference. These macro-evolutionary studies are often too crude to trace the different steps in the process of speciation. Work on speciation in the fields of evolutionary ecology and molecular biology focuses on micro-evolutionary processes. It uses observations and experiments over tens to thousands of generations, for example in model organisms with rapid generation turnover such as bacteria, but due to the briefness of the interval studied, these disciplines commonly offer only partial answers. Although recently some breakdown of the methodological distinction between these research fields has occurred, the time scales commonly adopted to study speciation are either too long or too short to study speciation, resulting in what is known as an "epistemological gap" (e.g. Kemp 1999; Reznick & Ricklefs 2009).

Rationale. The Great Lakes in the East African Rift system are renowned for the study of speciation. They have been referred to as 'natural laboratories of evolution' (e.g. Michel et al. 1992), mainly, but not exclusively, because of the large and diverse species flocks of cichlid fish that inhabit them. Although these fish have played a pivotal role in speciation research (e.g. Seehausen et al. 2008), their principal disadvantage is the lack of a good fossil record to trace the process of speciation as it is unfolding in time. Fossil mollusk shells, by contrast, are preserved abundantly in lake-sediment deposits and often allow identification at the species level (Schultheiß et al. 2009). Freshwater mollusks inhabiting the East African Rift lakes have diversified through time much like the cichlids they coexist with, but their evolutionary changes are preserved much better in the fossil record. Hence they provide a truly unique opportunity to integrate neontological and paleontological evidence.

In order to unravel the process of speciation in great detail, one must study the same evolutionary event from both the neontological and paleontological sides. The paleontological evidence ideally consists of a stratigraphical record of abundant fossil specimens with high temporal resolution, so that it allows to measure morphological characteristics of fossil representatives of the studied species or set of species in subsequent sediment layers, i.e. it should allow tracing changes in the relevant features almost continuously over time. To study the same speciation event neontologically, the studied fossils must have direct descendants living today. These descendants can then be studied with the full range of methods available in modern ecology and genetics, e.g., the sequencing of molecular markers, direct ecological studies in the field, anatomical and morphological examinations and measurements, transplant experiments, etc.

Currently, I am studying a group of freshwater snails that meets the exceptional requirements indicated above, namely the various Bellamya species (viviparid gastropods) inhabiting Lake Malawi and adjacent waters in the Malawi Basin of southeastern tropical Africa. During my PhD studies on this group, we discovered that only a single Bellamya morphospecies lived in the southern part of the Basin during the early to middle Holocene (~10,000 to ~5,000 years ago), while four nominal species occur there today. These living Bellamya species are so young that most of their genes do not allow tracing their separation yet (Schultheiß et al. 2011), and three of the four species live together in habitat that before was occupied by their single, early to middle Holocene fossil ancestor.
