Overview

My research focuses on animal migration and its ecological consequences. I am particularly interested in the drivers of variation in numbers and species through migration hotspots, the interactions between co-migrants and resident species and the genetic basis of traits found in migratory organisms. If you are interested in PhD or postdoc opportunities, or would like any further information, then please get in touch. Want to see what life is like in the lab?

Research interests

Our research focuses on spectacular long-distance migrations of insects and investigates how these tiny organisms move over vast distances and the ecological consequences of these movements.

Research projects

Long-term monitoring and comparative analysis of migratory insect populations. We monitor insect movement through migration hotspots, including high mountain passes, islands and coastal areas. We have developed a number of methods to quantify the huge numbers of individuals involved and our emerging long-term datasets are used to investigate how environmental and geographic variation influences migrant numbers and species assemblages. We use our field sites to investigate a number of interactions between co-migrants and between migrants and resident species (predation, mutualisms, disease etc) in order to understand how these mobile ecosystems function.

Orientation and energetics in migratory hoverflies. Over 4 billion migratory hoverflies move over Britain each year. These species enter in spring, reproduce through summer and the subsequent generations leave in autumn, flying south to the Mediterranean basin. To achieve this, hoverflies may cover hundreds of kilometres in a single day and thousands of kilometres over the entire period. Yet we do not understand how they know when to leave, which way to head or how they power their journeys. To investigate these questions, we use state-of-the-art flight recording technology including flight-simulators, flight-mills and vertical-looking radar to investigate compass navigation and flight capabilities of migratory hoverflies: see here and here.

Environmental induction and genetic control of migration. We utilise transcriptomics and comparative genomics to identify the molecular determinants of migration in insects. In particular, this research aims to move our understanding of the genetics of migration from correlative studies, which identify genes potentially involved in migration, to a mechanistic understanding of how these factors actually function.

Hoverflies as dual ecosystem services providers ‘pollinators+’. Hoverflies visit many of the major global food crops worth around US$300 billion per year to the world economy. In addition, they provide ecosystem functions not seen in bees: crop protection from pests, recycling of organic matter and long-distance pollen transfer. We investigate a number of questions related to the ecological utilisation of hoverflies to improve agriculture: see here.

Understanding the complex regulatory networks underlying development and evolution of multi-cellular organisms is a major problem in biology. Computational models can be used as tools to extract the regulatory structure and dynamics of such networks from gene expression data. This approach is called reverse engineering. It has been successfully applied to many gene networks in various biological systems. However, to reconstitute the structure and non-linear dynamics of a developmental gene network in its spatial context remains a considerable challenge. Here, we address this challenge using a case study: the gap gene network involved in segment determination during early development of Drosophila melanogaster. A major problem for reverse-engineering pattern-forming networks is the significant amount of time and effort required to acquire and quantify spatial gene expression data. We have developed a simplified data processing pipeline that considerably increases the throughput of the method, but results in data of reduced accuracy compared to those previously used for gap gene network inference. We demonstrate that we can infer the correct network structure using our reduced data set, and investigate minimal data requirements for successful reverse engineering. Our results show that timing and position of expression domain boundaries are the crucial features for determining regulatory network structure from data, while it is less important to precisely measure expression levels. Based on this, we define minimal data requirements for gap gene network inference. Our results demonstrate the feasibility of reverse-engineering with much reduced experimental effort. This enables more widespread use of the method in different developmental contexts and organisms. Such systematic application of data-driven models to real-world networks has enormous potential. Only the quantitative investigation of a large number of developmental gene regulatory networks will allow us to discover whether there are rules or regularities governing development and evolution of complex multi-cellular organisms.

BACKGROUND: Lbx/ladybird genes originated as part of the metazoan cluster of Nk homeobox genes. In all animals investigated so far, both the protostome genes and the vertebrate Lbx1 genes were found to play crucial roles in neural and muscle development. Recently however, additional Lbx genes with divergent expression patterns were discovered in amniotes. Early in the evolution of vertebrates, two rounds of whole genome duplication are thought to have occurred, during which 4 Lbx genes were generated. Which of these genes were maintained in extant vertebrates, and how these genes and their functions evolved, is not known. RESULTS: Here we searched vertebrate genomes for Lbx genes and discovered novel members of this gene family. We also identified signature genes linked to particular Lbx loci and traced the remnants of 4 Lbx paralogons (two of which retain Lbx genes) in amniotes. In teleosts, that have undergone an additional genome duplication, 8 Lbx paralogons (three of which retain Lbx genes) were found. Phylogenetic analyses of Lbx and Lbx-associated genes show that in extant, bony vertebrates only Lbx1- and Lbx2-type genes are maintained. of these, some Lbx2 sequences evolved faster and were probably subject to neofunctionalisation, while Lbx1 genes may have retained more features of the ancestral Lbx gene. Genes at Lbx1 and former Lbx4 loci are more closely related, as are genes at Lbx2 and former Lbx3 loci. This suggests that during the second vertebrate genome duplication, Lbx1/4 and Lbx2/3 paralogons were generated from the duplicated Lbx loci created during the first duplication event. CONCLUSION: Our study establishes for the first time the evolutionary history of Lbx genes in bony vertebrates, including the order of gene duplication events, gene loss and phylogenetic relationships. Moreover, we identified genetic hallmarks for each of the Lbx paralogons that can be used to trace Lbx genes as other vertebrate genomes become available. Significantly, we show that bony vertebrates only retained copies of Lbx1 and Lbx2 genes, with some Lbx2 genes being highly divergent. Thus, we have established a base on which the evolution of Lbx gene function in vertebrate development can be evaluated.

Walliker T (2021). Bird and Insect migration through Cyprus and the eastern Mediterranean region.

Twice each year, vast numbers of birds and insects undergo poleward migrations. Species which cross between Europe and Africa must negotiate traversing the Mediterranean region. Many birds are known to avoid crossing seas and therefore in the east they bypass the Mediterranean by taking an overland route and migrating through Israel, Lebanon and Syria. However, some birds do make the sea crossing and use Cyprus as a steppingstone between Africa and Europe. Despite widespread knowledge of this route, no dedicated studies on bird migration have been carried out in the north of Cyprus, and no season-long assessments of insect migrants has been carried out on the island. From March through to May of 2019, a team of five University of Exeter students surveyed insect and bird spring migration occurring through the northeast peninsular of Cyprus over a 39-day period; this survey was to be repeated in spring 2020, but the COVID-19 pandemic rendered fieldwork impossible. In Chapter 1 observations of bird migration on Cyprus were contextualised by comparing them with ornithological radar data from Israel (a known migratory hotspot), then assessing broad migration trends and the effect of wind on bird migration intensity. In agreement with existing studies, larger birds like raptors were less impacted by wind currents than smaller birds such as songbirds. Moreover, when beneficial tailwinds were scarce, songbirds chose to migrate in lower wind speeds. Migration traffic rates for day-migrating birds were found to be proportionally greater over the Karpaz peninsular than in the Hula valley of Israel. Thirdly, temporal migration patterns for raptors over Cyprus and Israel correlated significantly. Chapter 2 takes a natural history focus by detailing the taxonomic assemblages of migrants recorded on Cyprus, and then discussing the implications of our findings. Higher than expected numbers of migrating crag martins (Ptyonoprogne rupestris), common kestrels (Falco tinnunculus) and pallid harriers (Circus macrourus) for Cyprus were recorded during our spring survey. Observed numbers for pallid harriers suggest that the Karpaz peninsular may possibly be Europe’s most significant flyway for the species. These provisional findings are of great conservation importance as pallid harriers are listed as a globally near threatened species on the IUCN Redlist. In addition, the first African migrant butterfly (Catopsilia florella) on Cyprus since 1986 and the first ever Cyprus record of the ladybird Harmonia quadripunctata were recorded. Furthermore, evidence of mass migratory behaviour in the flies Delia platura and Stomoxys calcitrans is presented, both of which were not previously considered migratory. Observations of signs of illegal bird trapping at the Cyprus study sites is discussed anecdotally.
