I’m interested in linking community ecology processes, such as species-interactions and dispersal, with biodiversity and ecosystem functioning at larger, regional scales. Much of my interest is on metacommunity and meta-ecosystem dynamics in dendritic, river-like networks. Learn more about my research and teaching.

Besides my interest in conceptual community ecology, I’m also a keen naturalist. My pleasures are–as Vladimir Nabokov said once–the most intense known to man: writing and butterfly hunting (with the camera). Read more about my passion for Lepidoptera.

As a research assistant in the Altermatt lab, my goal is to establish well-founded knowledge about the distribution and diversity of native and non-native amphipod species in Switzerland. I want to gain a deeper insight into processes forming biodiversity patterns over time and space. Dendritic aquatic systems represent a suitable study system wherein different ecological and evolutionary mechanics, such as dispersal, invasion and speciation, can be studied.

I am studying phenotype diversity and diversification within the subterranean amphipod genus Niphargus. A part of my research is dedicated to the on-going taxonomic revision of the genus, the other part to studying mechanisms underlying its evolutionary radiation.

Vid Švara

PhD student, Helmholtz Centre for Environmental Research

Vid is a PhD student at the department of Effect-Directed Analysis since December 2017. In his project, he focuses on effects of genotoxic substances on freshwater amphipods. He is interested in the effects of potentially genotoxic substances in the effluents from wastewater treatment plants on the genetic diversity of amphipods living in affected habitats. His main tasks include chemical screening of the water samples using liquid chromatography and mass spectrometry, genetic comparison of amphipod populations and a variety of bioassays.

Vid completed his Bachelor and Master’s degrees at the University of Ljubljana where he worked on the diversity and evolution of freshwater amphipods. During his Master’s, he also studied at the Ludwig-Maximilian University of Munich in the program Evolutionary Genomics, Ecology and Systematics. In his Master’s thesis, Vid analyzed the morphological, ecological, and genetic diversity of cryptic amphipod species from the genus Niphargus. Additionally, he has performed an internship at the Museum für Naturkunde in Berlin, worked in the Zoological State Collection in Munich, and did a research stay at the EAWAG center for aquatic research in Zurich where he focused on the physiological and ecological diversity of freshwater amphipods.

In his free time, Vid enjoys photography and butterfly diversity research.

My research revolves around what drives biodiversity and species distributions at local and regional scales. I’m also particularly interested in the impacts of global change and other anthropogenic factors and how we can best predict future changes in species occurrences. In my PhD I’m examining aquatic-terrestrial linkages using a meta-ecosystems framework, working primarily with amphipods. Dendritic network provide an excellent opportunity to study these issues due to their spatial organization and the delineation between aquatic and terrestrial ecosystems, which allow us to easily identify the origin and movement of materials and organisms between the two settings.

Research Assistant, Eawag

My interests are mainly focused on aquatic ecology and evolution. Seeing species communities as structured and highly interactive networks enables me to investigate a wide range of organisms often times finding similar underlying mechanisms shaping intra- and interspecific ecological and evolutionary patterns. As a scientific assistant at the Altermatt Lab my goal is to test and establish experimental laboratory facilities and standardized methods suitable for successfully keeping and hopefully also rearing various populations of amphipods. Besides my scientific interests I’m a passionate fisherman enjoying nature and fishing for amphipod feeding fish.
