List of publications before starting work at the Umwelt-Campus

Nina N. Kaiser, research associate

I work as a project manager in the collaborative research project "Traunbach" together with the Ministry for Climate Protection, Environment, Energy and Mobility of the State of Rhineland-Palatinate. Here we are investigating how a multi-criteria water management plan can be developed in a participatory process, which not only aims at the good ecological status but also integrates other ecosystem services (2021-2023).

In my PhD thesis I focus on ecosystem services of restored rivers (cooperation with the WG Aquatic Ecology, University of Duisburg-Essen). I explore which characteristics restoration must have in order to lead to a sustainable increase in ecosystem services, especially cultural ecosystem services. I also consider the interactions of ecosystem services and biodiversity in the context of habitat restoration. My doctorate is embedded in the project "Optimization of Restoration for Biodiversity and Ecosystem Services" and is funded by the Bauer Foundation and Rudolf-und-Helene- Glaser Foundation.

Wolfram Remmers, scientific associate

As a scientific assistant in the ecology lab I work on a diverse set of topics and projects in science and education. The focus of my work lies on the analysis of ecological data from streams in and around the Nationalpark Hunsrück Hochwald and determination of aquatic invertebrates.
At the moment I am involved with the following topics and projects: long term ecological monitoring of streams in the national park, ecological monitoring of the Steinbach Reservoir, ecological assessment of stream restorations and “BlauPlus” projects, the school project “Our Common Future” of the Robert Bosch Foundation as well as the creation of information panels at a restoration site.
For my Phd at the University of Koblenz-Landau I investigate distribution patterns of the killer shrimp (Dikerogammarus villosus). I am particularly interested in the effect of environmental factors on biotic interactions and the formation of stable distribution barriers for D. villosus.

Elodie Boussinet, doctoral candidate

During my PhD thesis, I will be able to develop strong knowledge on the life-history trait of Allis shad population, Alosa alosa, in the Rhine and carry out an implementation of successful monitoring for Allis shad spawners. For this purpose, fishes are collected along the Rhine and its tributaries. Using the microchemistry, otoliths (ear stones of fish) of juveniles and spawners are used to understand the migration pathway during the downstream migration as well as to know which fishes resulted from a natural reproduction in the Rhine or which come from the reintroduction program for the Allis shad since 2007 (i.e., from the Gironde system, South-West of France). Coupling the daily age with otoliths microchemical composition (Sr isotope, Sr:Ca, Ba:Ca and Mn:Ca) and water composition, I will deduce most precisely the migration pathway of each fish.

Lucas Mignien, doctoral candidate

In my Ph.D. thesis, I am investigating the effects of hydrological variability, especially extreme hydrological events (floods and droughts) on fish communities and their microhabitat use patterns. By combining data driven analysis and experimental approach, the effects of these extreme events will be investigated on several temporal and spatial scales to have a synthetic overview on how fish communities are impacted. The experimental setup consists in a network of PIT tag antennas implemented in a braided stream section located at the Hunsrück-Hochwald National Park. This technology will allow us to detect small-scale movement patterns and microhabitat use of each fish in this stream. The data will be used to analyze diurnal, seasonal and event-based movement and microhabitat use patterns as well as intra- and inter-specific spatial interactions. Habitat modeling (PHABSIM, CASIMIR) is applied to compare predicted and observed microhabitat use patterns.

Lara Hoffmann, doctoral candidate

My PhD thesis examines the effects of short rotation coppice (SRC) on butterfly diversity in the agricultural landscape. Short-rotation plantations are fast-growing tree species that can be cultivated on agricultural land (no forest in the sense of the BWaldG), such as poplars, willows or robinias.
In the first part of my PhD thesis, I explore how butterfly diversity depends on the age of a short rotation plantation and how butterfly caterpillars are distributed over the different levels of the leaf canopy (succession ecology). From the statements on the preferred growth stages of butterflies and the height-zone differentiation of the caterpillar community, biodiversity-optimized rotation phases and harvesting methods can be determined.
The second part of the PhD thesis aims at the further development of the SRC to a possibly effective nature conservation measure. It aims to enable statements, which locations SRC should be given priority for establishing SRC in the agricultural landscape, so that they can develop a possible advantage to the butterfly diversity.
The third part of the PhD thesis is dealing with the economic profitability of a biodiversity optimized SRC. New management tools, such as the SRC, have to be implemented quickly by farmers and have to be compared with other crops. If the economic profitability is not given or turns out to be unattractive compared to alternative land use alternatives, the dissertation also aims at the identification of possible funding needs by politics.

Heiko Schmidt, doctoral candidate

In my doctoral thesis I am working on the development of a prediction tool to assess the success of renaturation measures by combining a species distribution model and a fish distribution model. The tool shall enable spatial-explicit predictions on the effects of renaturation on fish biodiversity and thus a spatial prioritisation of renaturation as well as the consideration of project alternatives. The PhD thesis is a cooperation between the AG Aquatische Ökologie of the University of Duisburg-Essen and University of Applied Science Trier.

Karolína Kalinová

At the University of South Bohemia in the Czech Republic I studied Environmental Management with a specialization in Landscape Ecology from where I graduated with a Bachelor degree, followed by a Master degree in Ecosystem Biology with a specialization in Conservation Biology.

Currently I have been working on a project dealing with visitor information and environmental education in German national parks – namely NP Bayerischer Wald and NP Hunsrück-Hochwald – within the internship of the German Federal Environmental Foundation (Deutsche Bundesstiftung Umwelt – DBU).

My interests include birdwatching, hiking and choral singing.

Dr. Alessandro Manfrin, postdoc

Alessandro Manfrin

My interests include theoretical and applied ecology, conservation and evolution, as related to freshwater and terrestrial ecosystems. I combine observational and experimental studies, both in the field in laboratory setting to gain a better understanding of the interactions between multiple stressors. I developed particular competence in the analysis of large spatial and temporal dataset adopting linear and non-linear mixed-effects modelling in which potential spatial and serial dependency are considered. My interest is to continue my carrier in science

Lena Kusanke worked on the "environmental DNA" aspect in the cooperation project "Schlammpeitzger" (European weather loach) with University of Koblenz-Landau. Personal Information

Dr. Thomas Meißner

Focus of my previous work were structural and functional changes of aquatic biocoenoses under influences of anthropogenic stressors. In my dissertation, I am investigating the effects of dams on selected ecological components in the lower reaches. In the course of this work, I dealt extensively with hydrological changes, their quantification and the effects on fish and the benthic invertebrate communities.
Here at the Umweltcampus I mainly work on the cooperation project, focus of my daily work is the coordination and implementation of the “WasserWissensForum”, the design and supervision of internships, as well as the scientific support of selected BlauPlus projects and their performance control.
