MosquitoLUX – Atlas of the mosquitoes of Luxembourg

Abstract

Culex modestus, first detected in June 2019 in Remerschen.

The project MosquitoLUX (2019-2022) aims to compile and complete knowledge on mosquitoes (Diptera: Culicidae) in Luxembourg. In a context of climate and environmental change, this first mosquito atlas should make it possible to draw up an inventory of Culicidae fauna, in terms of biodiversity first, but also in terms of public health and vector risks. The latter requires not only the collection of presence/absence data, but also abundance and seasonality according to different environments. This inventory should also make it possible to detect introduced invasive alien species and changes in the distribution areas of native species.

Genetic monitoring of the pool frog and the edible frog in Luxembourg

Abstract

Nowadays, most animal species can be identified genetically by sequencing a fragment of the mitochondrial barcoding gene COI. However, for some species, this method is not applicable due to a more complex genetic make-up, often due to hybridisation.

One of these exceptions are the green frogs (pool frog – Pelophylax lessonae, edible frog – P. kl. esculentus and marsh frog – P. ridibundus). This group of frogs has an especially complex genetic composition due to hemiclonal hybridisation and polyploidisation.

To establish a genetic monitoring tool-kit for green frogs in Luxembourg, we will first apply ddRAD sequencing to a wide range of populations from the whole country. This high-throughput sequencing based method will be used to generate hundreds of genome-wide genetic markers. The resulting dataset will allow to identify individuals on species level and to assess their ploidy. Furthermore, it will enable an estimation of the genetic diversity of the two common species in Luxembourg, the pool frog and the edible frog.

In a second step of the project, these genetic data will be used to establish genetic markers for standard genetic monitoring in Luxembourg and to develop recommendation guidelines for their application.

DNADIVE: eDNA Detection for crayfish invasIVE species in streams of Luxembourg: Development of a molecular toolbox


This public-public research project is supported by the
Luxembourg National Research Fund (PUBLIC2-17/SR/11816664)

Abstract

Oronectes_limosusDNADIVE aims at developing a toolbox for the molecular monitoring of invasive crayfish in the streams of Luxembourg. Three exotic species (Orconectes limosus, Pacifastacus leniusculus and Astacus leptodactylus) and a native one (Astacus astacus) will be targeted during this project. This molecular toolbox will encompass several techniques of detection comprising (1) a simple amplification method easily performed in a laboratory with few elements, (2) a digital droplet amplification (ddPCR) which is a more elaborated lab method that can allow for a higher detection sensitivity and a possible quantification of DNA that could be related through the proxy of biomass and abundance to the size of the populations detected and (3) an isotherm amplification method (iPCR) i.e. a simple, cost effective approach which will allow for a field detection usable by non-trained agents. The results will enable the development of a predictive species distribution model for the target species and allow to infer their impact on freshwater communities through the comparison with previous sampling campaigns.

This set of methods has the high potential to efficiently contribute to early detection and routine monitoring of the invasive crayfish species in Luxembourg, thus allowing for a timely and efficient decision-making and appropriate management.

Climate change, plasticity and genetic variation in Anthyllis vulneraria

Climate change, plasticity and genetic variation in Anthyllis vulneraria

Abstract

Climate is a key factor determining plant distribution. Predictions of rapid climate change have resulted in a renewed interest in the possible responses of plants to changes in climate, such as migration to other localities, phenotypic plasticity and local adaptation. The aim of this project is to study the possible impact of predicted climate change on the short-lived perennial plant Anthyllis vulneraria along environmental gradients. We will analyze natural populations and their habitats along altitudinal and latitudinal gradients to investigate relationships between population characteristics and environmental conditions. We will also investigate molecular genetic diversity in relation to the same gradients. The variation in a number of quantitative traits and its distribution among spatial scales will be studied in a lowland common garden and compared with that of the variation in neutral genetic markers.

We will test whether plants from mountain and high latitude populations perform less well under lowland conditions than plants from lowland and central European populations, and whether genotypes exist in the mountain and high latitude populations that are preadapted to the predicted warmer future conditions. Plants will be genotyped to detect loci correlated with ecological gradients which are of ecological relevance in A. vulneraria.

Predicted higher temperatures are likely to increase the frequency of drought. To assess the role of plasticity and evolutionary adaptation in the response to increased droughts, both the plastic responses of high latitude / altitude and lowland populations to drought and genetic variation in drought resistance will be studied experimentally. The expected results will contribute to a better understanding of the role of plasticity, genetic diversity and local adaptation of short-lived grassland plants under predicted climate change. The outcomes will also have implications for the conservation and management of biodiversity.

Evolutionary potential of the raccoon roundworm

Full title

Using population genetics to understand the evolutionary potential of an introduced parasitic nematode, the raccoon roundworm (Baylisascaris procyonis)

Abstract

Parasitic nematodes can cause serious diseases and their emergence in new areas can be an issue of major concern for human health, agricultural productivity and biodiversity conservation. Molecular studies of nematode invasions can make a significant contribution to a better understanding of the underlying mechanism of the emergence, spread and persistence of the parasites. Also, they will clarify the evolutionary potential of the invaders in their new range and help with the elaboration of adequate management strategies against helminthic disease. The raccoon roundworm (Baylisascaris procyonis) is a common gastrointestinal parasite of the raccoon (Procyon lotor), that is emerging as an important helminthic zoonoses that mainly affects young children. Translocations of raccoons have increased the global geographic range of its roundworm as well. Raccoons are particularly abundant and wide-spread in Germany, where they can occur at high densities in urban areas. Recent genetic work has provided evidence for at least four independent introduction events, which gave rise to genetically differentiated subpopulations in incipient contact of relatively high genetic diversity. The roundworm, however, does not occur in all raccoon populations and might therefore be much less genetically diverse due to reduced propagule pressure. The overall objective of this study is to use population genetic techniques to analyse the genetic diversity and gene flow in the invasive nematode B. procyonis to understand the evolutionary potential of the parasite and allow the implementation of successful control programmes. We aim in particular to establish how frequently the parasite was introduced into Western Europe, to estimate the geographic origin of the introduced parasites, to examine the changes in genetic diversity during the invasion process and to the landscape genetic structure of the raccoon and its roundworm in parallel.

Effects of Robinia pseudoacacia on understory vegetation

Full title

Invasion of Robinia pseudoacacia in Europe and its effects on understory vegetation in urban and rural areas

Abstract

The aim of this PhD study is to assess the invasion of the legume Robinia pseudoacacia in Europe and its effects on understory vegetation in terms of species composition and richness, with a focus on other alien species, which might have advantages, growing under this alien tree species. Furthermore the effect of urbanization will be taken into account. Until now Robinia is known to invade dry grasslands and urban wastelands, thus diminishing their usually high biodiversity. In woods it is known to respond well to anthropogenic disturbances and coppice forest management. All previous studies were conducted on a local to regional scale. This study will broaden the view of Robinia Invasion in forests; the study area shall extend from Hungary to western France, with Luxembourg as a main central point. Methodologically, the study will examine pairs of wood stands, on one hand, stands composed of Robinia and stands composed of native wooden species, under similar environmental conditions, will be compared. On the other hand stands in urbanized environments will be compared to stands in rural regions. The main variables, that will be gathered, are species composition (α-, ß-diversity), climate data (on a larger scale) and soil features, mainly the N-content of the soil, as Robinia has the capability to bind atmospheric nitrogen. In the end we hope to have an answer to the following questions:

  • Does Robinia pseudoacacia pose a threat to certain native European woodland communities in certain regions?
  • Does it change soil factors in a way to favour other alien species and to change biodiversity?
  • Is there a difference between urban and rural stands?

Landscape genetics of ungulates

Full title:

Using comparative landscape genetics to assess connectivity in fragmented landscapes and identify functional ecological networks

Abstract

Habitat fragmentation has been recognised as one of the key threats to wildlife worldwide. Protected areas are usually considered to be the cornerstone of biological conservation as they are expected to represent the best areas available to ensure the persistence of biodiversity and thereby counteract the negative effects of fragmentation and habitat loss. However, existing protected areas, particularly in Europe, are often too small to maintain viable populations and it has been suggested that the interconnectivity of protected areas should be considered of the same importance as the sites themselves. Preserving, improving and restoring connectivity and movement corridors in fragmented landscapes are therefore essential elements in any conservation strategy. Recently, researchers have started to relate gene-flow patterns to landscape features in order to assess the extent to which landscape elements hinder or facilitate the movement of individuals. The main objective of this study is to use genetics-based resistance surfaces to perform rigorous landscape connectivity analyses in order to test how well regional sets of protected areas in Europe are integrated into functional ecological networks. While these landscape genetic approaches provide a key foundation for rigorous analysis of landscape resistance to movement, there are, however, a number of important basic questions related to optimal study design where additional research is needed to advance the field of landscape genetics and to make outputs for conservation planning more robust. Specifically, working on three mammal species, I want to (a) replicate species-specific landscape genetic analyses across multiple European study areas to test if the same landscape features are found to be influencing gene flow in different regions, (b) perform landscape genetic analyses on co-distributed species to test if the same landscape features are found to be influencing gene flow in different species in the same study area, (c) assess the influence of sample size on which landscape features are found the be influencing gene flow and (d) use the results from the landscape genetic analyses to derive empirically-validated movement corridors (for individual & multiple species) and to assess how well these are integrated into established protected area networks.

Genetic studies on Saxifraga rosacea

Full title: Consequences of ploidy level on the reproductive isolation, ecological niche differentiation and plasticity of two subspecies of Saxifraga rosacea.

Abstract

Despite technological advances at the molecular level, it is still difficult to differentiate two subspecies of closely related taxa. It is often necessary to combine genetic techniques with ecological studies to distinguish each of them. The main purpose of the present project is to assess the importance of ecological niche differentiation that can be found between two closely related species with different ploidy levels. We will cross by artificial pollination, two subspecies of Saxifraga rosacea: Saxifraga rosacea subsp. rosacea (hexaploid) and Saxifraga rosacea subsp. sponhemica (tetraploid), and measure the offspring performance and establish whether the differences in ploidy levels create a reproductive isolation. We will also test the ecological isolation of both subspecies by measuring various environmental habitat characteristics like temperature or humidity. These measures will help to determine the optimal environmental conditions for the establishment and survival of the two subspecies. We will also study their demography, with measures at different life stages of the two sub-species to determine their life cycle. Finally we want to test the plasticity and adaptation of Saxifraga rosacea subsp. rosacea and Saxifraga rosacea subsp. sponhemica using climate chambers with controlled conditions in temperature and/or hygrometry. A common garden experiment will be conducted at the MNHNL with both subspecies in order to study the plasticity and robustness to environmental treatments such as hydric stress and competition by other species. The expected results will enable us to complete the results of a current PhD project of the museum, which focuses on the phylogenetic and phylogeographic aspects of the two subspecies and to allow a better understanding of particular links between speciation, plasticity and adaptation. Our results will also have implications for the conservation and management of these taxa. Saxifraga rosacea subsp. sponhemica is an endangered species of special conservation interest as a large number of the known extant populations occur in Luxembourg.

Macroevolutionary pattern of belemnites

Full title: Macroevolutionary pattern of belemnites (Mollusca, Cephalopoda) from the Lower Jurassic: a multidisciplinary approach.

Abstract

It is now widely assumed that the current erosion of biodiversity is a significant phenomenon in Earth’s history.  Understanding the dynamics of past extinctions seems crucial if we are to put the attrition of biodiversity into perspective. Since the pioneering work of Raup & Sepkoski, many palaeontological studies examined the role of extinction selectivity on macroevolutionary patterns in relation to the geographical range, life-span, morphology and ecology of taxa. Palaeontology tends to adopt an approach of methodological uniformitarianism by appealing to causes observable at the present time, before seeking extraordinary explanations for observed evolutionary patterns.

The present project basically aims to contribute to this topic, using paleontological data as palaeobiodiversity model. Its main interest is to explore biodiversity through time, which is obviously not possible for present taxa based studies. The present project focuses on belemnites (Mollusca, Cephalopoda), which have surprisingly never been studied in this context, and will focus on the Pliensbachian–Toarcian period (~190–175 Ma), which encompassed one of the most important marine crises of the Mesozoic, affecting groups such as ostracods, foraminifers and ammonites.

The present project will investigate the following questions:

  1. What are the main macroevolutionary patterns of belemnites during this period?
  2. Are there any biogeographical pattern changes during the studied period?
  3. What are the palaeoenvironmental and biological triggers of macroevolutionary and biogeographical changes?
  4. Are the patterns different from those observed for other taxa, and specially ammonites?

However, reaching these main objectives imply to get a good knowledge of belemnites species for the studied period. Recent results based on taxonomic revision or quantification of intra- and interspecific variations call for a reappraisal of species, particularly taking into account shape variation for their recognition. For this reason, the present project explicitly includes a first step of basic studies of belemnites in order to get a homogeneous database, based on a reappraisal of species. This is the first objective to reach before addressing macroevolutionary questions.

Finally, these nektonic cephalopods, are widely used to constrain palaeoenvironments using the isotopic signal of their rostrum. A reappraisal of species definition, and a better knowledge of their ecology will obviously conduct to have a fresh view on geochemistry interpretation.

Plant-animal interactions and climate change

Abstract

The biological diversity of montane regions may be threatened by predicted climate change. Low mountain species frequently cannot respond to climate change by migrating upward, but only by plasticity or genetic adaptation. Predicted climate change will not only result in changed environmental conditions, but also affect biotic interactions. The aim of this project is to study the possible impact of climate change on the interactions of the threatened plant species Arnica montana with both generalist herbivores and a specialised parasite, the seed fly Tephritis arnicae. We will investigate the impact of herbivory and parasitism on the model species A. montana along an altitudinal gradient, investigate defenses against herbivores using metabolomic profiles, and experimentally study how plant-animal interactions would be affected under predicted climatic change. Population sizes of generalist herbivores are foreseen to increase in upland regions which may threaten the survival of mountain populations of plants that may be less defended against herbivores than lowland populations. We will also study genetic variation in metabolomic profiles and herbivore resistance among and within populations and its importance for adaptation to changed conditions. The population biology of A. montana is currently studied in a PhD project (AFR FNR Grant) hosted by the MNHNL. The proposed PhD project will take advantage of the knowledge about the population biology and quantitative genetics of A. montana obtained in this study and use two common garden experiments already set up at high and low altitudes. The expected results of the project will contribute to a better understanding of the genetic and metabolomic diversity of rare and endangered species and its importance under the scenario of projected climate change. The outcomes will also have implications for the conservation and management of biodiversity and allow a better understanding of the role of systems biology in biodiversity conservation.
