Comparative limnology of African lakes, and environmental regulation of their aquatic invertebrate communities

African lakes range from small crater lakes to the largest and oldest tropical lakes in the world, and from cold and dilute alpine tarns to hot and hyper-saline soda lakes. The functioning of these tropical aquatic ecosystems is still rather poorly understood, because food-web structure and nutrient cycling are different than in north-temperate lakes, and because multi-annual environmental variability plays a more prominent role in long-term ecosystem dynamics. In this research theme, we focus on comparative study of physical and chemical limnology in this great diversity of African lakes, and on the environmental regulation of their aquatic invertebrate communities. These studies generate improved understanding of the causal links between the lakes’ modern-day functioning and the signatures of past environmental conditions incorporated in their sedimentary record; and leads to the development of diverse groups of micro-crustacea (e.g., Cladocera, Ostracoda), insect larvae (e.g., Diptera Chironomidae) and other aquatic biota as biological indicators of past changes in temperature, water chemistry, oxygen regime, nutrient cycling and substrate availability in African lakes. Besides fundamental interest, we also use this knowledge to develop models of lake vulnerability to water quality loss resulting from excess nutrient input and catchment soil erosion, to guide the conservation and management of scarce water resources in intertwined contexts of increasing demographic pressure and climate change.

Past climate change, human impact, and the environmental history of African ecosystems

Sediments accumulating on the bottom of African lakes represent one of the most valuable natural archives of tropical climate and environmental history, at both short (years to decades) and long (centuries to millennia) time scales. This history is written in a diverse range of sedimentological, geochemical and biological signatures contained in these sediments, each of them revealing part of the intriguing story of how the lake, its surrounding landscape, and the region’s climate have changed through time. Paleo-environmental reconstruction using Africa’s lake-sediment archives compensates for the lack of historical monitoring data by producing the long-term perspective needed to develop sound strategies for water-resource management and adaptation to climate change. In this research theme, we first aim to identify African lakes with the highest-quality sedimentary archives, and then exploit those archives to address a wide range of both fundamental and applied research questions such as long-term climate and ecosystem dynamics, the timing and magnitude of ancient human impact on Africa’s lakes and landscapes, and the assembly and regulation of aquatic biological communities in fluctuating tropical lakes. Fossils of aquatic invertebrates are among the most valuable indicators of the environmental change that lakes have experienced, be it natural (climate-driven hydrological change, ecological succession) or anthropogenic (eutrophication, fish introduction, siltation). Increasingly we also aim to calibrate and validate biological indicators of environmental change in the surrounding terrestrial ecosystem, such as fungal spores and the pollen and phytoliths of higher plants, to achieve a more comprehensive understanding of past climate-human-ecosystem interactions.

Taxonomy, biogeography and evolution of African aquatic biota

Systematics is the branch of evolutionary biology that studies the diversity of and relationships between species, and analyses their evolution in space and time. Taxonomic knowledge of tropical aquatic faunas lags behind that of faunas in north-temperate regions, resulting in incomplete classification of biological diversity, despite its crucial role in both fundamental and applied ecological research and biodiversity conservation. We study a wide range of aquatic biota, including Cladocera (water fleas) and Ostracoda (seed shrimp) among the microcrustacea, Chironomidae (non-biting midges) and Odonata (dragonflies and damselflies) among the aquatic insects, and Mollusca (snails and mussels). Most of these groups enjoy good fossil preservation, permitting direct links between historical biogeography, species evolution and the history of environmental change. Our morphological and biogeographical studies are combined with molecular phylogenetics and phylogeography, to provide better insight in the diversity, species relationships, and the evolutionary history of each group. One particular project exploits the excellent fossil record of fish teeth in African lake sediments to trace the colonization, environmental adaptation and evolution of cichlid fishes in an isolated crater lake.

Genetic and paleoecological signatures of African rainforest dynamics (AFRIFORD)


The Central African rainforest hosts remarkable biodiversity that is currently under threat, yet its evolutionary history is barely known. To predict its fate in response to ongoing rapid environmental change, this project seeks to understand how past climate changes and the activities of ancient indigenous societies have shaped the current distribution and composition of African rainforests and the genetic diversity of their constituent tree species. This will be achieved through multi-disciplinary research integrating paleoecological analyses (palynology, anthracology) on lake sediments and soils, dendrochronology, vegetation modeling and population genetics. Phylogeographic patterns and molecular signatures of past differential selection and demographic events (population fragmentation, expansion) in characteristic tree species will be interpreted in relation to (1) detailed reconstructions of vegetation and fire dynamics in recent millennia using lake-sediment archives, (2) soil anthracological data to document the timing and spatial extent of Holocene fire disturbance, and (3) climate-vegetation model simulations of the climate and environmental processes controlling rainforest distribution and productivity. This conjunction of genetics, paleoecology and vegetation modeling will, for the first time, allow to build a cross-validated scenario of tree species response (distribution range, adaptation) to environmental change in the African rainforest.

Patterns and mechanisms of climate extremes in East Africa (PAMEXEA)


Recurrent drought is the principal weather-related hazard for vulnerable populations and socio-economic systems in semi-arid East Africa, and the quality of weather and climate prediction is a principal bottleneck hampering drought mitigation and adaptation to scarce and unpredictable water resources. The principal goal of PAMEXEA is to understand how processes of natural climate variability and their feedbacks interact with anthropogenic climate forcing to create trends in rainfall and drought at inter-annual and decadal time scales. To achieve this, PAMEXEA will (1) calibrate and extract 1000-year time series of seasonally-resolved information on past weather extremes from the annually-laminated sediment records of two lakes in north-central and southeastern Kenya; (2) quality-screen and synthesize all available climate-proxy time series from East Africa to produce a spatially-resolved regional history of past climate variability; (3) use inverse hydrological modeling to translate reconstructed local moisture-balance histories into time series of past rainfall; and (4) test the hind-casting performance of existing climate models as a guide to their skill in simulating future climate trends over East Africa under realistic combinations of natural and anthropogenic climate forcing. PAMEXEA results will contribute to better seasonal and longer-term forecasting by serving as reference frame for development of next-generation climate models.

Two glacial-interglacial cycles (ca. 250,000 years) of climate and ecosystem dynamics on the East African equator (DeepCHALLA)


Long climate records from (sub-)tropical continental regions provide an important counterpoint to the polar ice-core records from Antarctica and Greenland, and are crucial to resolve long-standing questions about the relative importance of tropical and high-latitude climate processes in generating spatial climate variation. DeepCHALLA aims to exploit the continuous sediment record of Lake Chala near Mt. Kilimanjaro in eastern equatorial Africa. This is a highly appropriate region to pursue a long equatorial climate record, because here seasonal migration of the Intertropical Convergence Zone (ITCZ) spans the widest latitude range in the world, and hence atmospheric dynamics associated with northern and southern hemisphere monsoon systems interact most strongly. Lake Chala’s proximity to the Indian Ocean also ensures its all-season location east of the Congo Air Boundary, the zone of convection between Atlantic and Indian Ocean moisture sources. Consequently the region is not directly impacted by the climatic effects of changes in tropical Atlantic thermohaline circulation, through which signatures of northern hemisphere glaciation are transferred to low-latitude continents. DeepCHALLA’s principal objective is to acquire high-resolution and well-dated proxy records of continental climate and ecosystem dynamics near the equator over the past ca.250,000 years, thus encompassing two complete glacial-interglacial cycles and the entire known existence of modern humans (Homo sapiens) in East Africa. The length of this climate archive, combined with the exquisite temporal resolution provided by finely laminated sediments, provides unique opportunities to increase understanding of tropical climate variability at inter-annual to millennial time scales, including the occurrence of short-lived weather extremes (droughts, floods) with disproportionate impact on regional water resources and economic activity. The project includes a special focus on differentiating the histories of three fundamental aspects of the tropical hydrological cycle: annual rainfall, effective moisture, and the duration/severity of seasonal drought. Documentation of long-term biodiversity patterns and the ecological dynamics of tropical savannah (grassland-woodland) ecosystems in response to changes in atmospheric CO2, temperature, moisture balance, and fire will help explain/predict the present-day/future prevalence of C3 and C4 plant species in tropical grasslands, and the past/future persistence of biodiversity hotspots in eastern Africa.

Resilience in East African Landscapes: Identifying critical tresholds and sustainable trajectories in past, present and future (REAL)


REAL focuses on the temporal, spatial and social dynamics of climate-human-landscape interaction in East Africa during the last millennium, with particular reference to dry environments of the Rift Valley and Laikipia plateau in central Kenya, and the Pangani and Amboseli basins in northern Tanzania and south-eastern Kenya. With a mixed topography between dry lowlands and wetter adjacent uplands, these areas present a range of human habitat along a natural gradient of land and water resources. The core objective of REAL is on understanding how indigenous societies, landscapes and ecosystems have responded to the large natural climate variability that is endemic to East Africa, as a key to develop strategies for adaptation to future climate change. Within the REAL programme, two UGent PhD projects use palaeoecological reconstructions of past human-environment interaction driven by natural climate variability to re-evaluate current estimates of indigenous landscape use based on extrapolated historical demographic data.

Vulnerability of tropical crater lakes to water-quality loss: a natural experiment in western Uganda


In East Africa, loss of water quality is a very real problem, as sustainable water resources are naturally scarce. This study assesses how the physical limnology of tropical African crater lakes, specifically their relative depth and frequency of deep water-column mixing, affects the vulnerability of their water quality and fisheries to different types of land-use within their catchment. This is achieved through comparative study of water-column mixing, algal productivity, nutrient budgets, and land use in 25 crater lakes in western Uganda. Using field data on the relationship between physical limnology and trophic status (water quality) in the study lakes, a model will be developed which enables predictions on the effects of specific lake management on other small tropical lake ecosystems in East Africa. This will allow strategic water-resource management to decide which lakes are most suitable for economical activity, and which lakes should be set aside for extraction of drinking water. Also it will allow to predict the regional water-resource consequences of increasing or decreasing precipitation resulting from climate change.

Zooplankton community dynamics in East African mountain lakes: integration of (palaeo-) limnology and (palaeo-) genetics


This project investigates the impact of decadal to century-scale variability in the climate (rainfall and temperature) of central Kenya during the late Holocene (the last ~2000 years) on the size and temporal dynamics of the glaciers on Mount Kenya, and on its high-mountain (Afro-alpine) aquatic ecosystems. This objective is pursued through multi-proxy analysis of long, dated sediment records from lakes on Mount Kenya itself and from Lake Bogoria in the nearby Rift Valley. Associated analyses of current lake-water chemistry and biological limnology are important for the correct interpretation of changes in the sedimentological and fossil biological proxies occurring in the sediment cores, from which we derive quantitative estimates of past climate changes in the region. Reconstruction of climate-driven changes in the depth and salinity of Lake Bogoria will produce the reference framework of regional climate history, permitting elucidation of temperature and precipitation controls on the advance and retreat of Mount Kenya glaciers. From Mount Kenya only, we will also collect plankton samples for genetic analysis of a selected group of zooplankton (water fleas, a group of microcrustacea) to help distinguish between native and exotic species occurring in Mount Kenya lakes today. Documentation of the current distribution of those exotic (invasive) species in relation to local habitat quality and co-occurring native species will allow rigorous evaluation of their current and future impact on the ecology of Mount Kenya lakes.

Research interests

I am integrative evolutionary biologist broadly interested in patterns and processes of organismal diversification, associated changes in morphological disparity, organism-environment interactions, and how diversity is structured in space and over time. What mechanisms are causing differentiation among populations, and ultimately reproductive isolation? How do speciation processes interact in space and time to result into evolutionary radiations? Do speciation mechanisms determine how prone the resulting taxa eventually are to extinction? How can we explain the often marked differences in 'evolutionary success' in even closely related branches of the tree of life? I am studying extant and fossil biota to address these and other questions. To do so, I integrate microevolutionary and macroevolutionary approaches, ranging from the study of genomic and morphological data from natural and experimental propulations in an environmental context, to contrasting predictions of evolutionary theory with empirical data. My main model system is the freshwater mollusks of the East African Great Lakes.

Other interests

  • Schistosomiasis and host-parasite co-evolution.
  • Phenotypic evolution and the relationship between morphospace occupation and phylogeny.
  • Lacustrine versus riverine evolution, driving mechanisms and differential ecological forces.
  • Historic biogeography, migration and evolution of African freshwater molluscs and the impact of paleoclimate on these.
