Ecology is the science about interactions, which define distributions of organisms, their abundances, and why they are found there. Ecologists study interactions between organisms and their environment on many different scales: from a single organism to the complex interactions within diverse communities; from a microhabitat of a rock crevice to the biomes of the Earth. Answers for mentioned questions where?, how many?, why? are important for understanding current, elucidating past and predicting future ecological processes.
What does ecology have to do with each one of us?
Numerous fields within ecology (e.g. population, landscape, functional, theoretical ecology) and its interdisciplinarity (with e.g. biogeography, evolution, genetics) help us to understand and improve our environment, as well as to protect natural resources and manage them in a sustainable way.
Our research topics are also subjects of student theses. We collaborate with researchers from Slovenia and abroad.
Bioinvasions – we study occurrences of non-native, invasive species, their invasiveness and invasibility of their habitats in the introduced range. We seek to understand the interactions between native and non-native species, as well as interactions among non-native species. Osredotočamo se na interakcije med avtohtonimi in tujerodnimi vrstami ter med tujerodnimi vrstami samimi. We largely explore urban and suburban environments and forest fragments. Research work takes place in the field and in the laboratory. We are interested in many non-native organisms – plants, beetles, signal crayfish, domestic cats and others.

Biology and ecology of species and populations in communities – we study mostly plant species or special plant functional groups (e.g. rare endemic Hladnikia pastinacifolia, endangered Helleborus dumetorum, invasives Pistia stratiotes, Potentilla indica, Impatiens parviflora, model species’ Glechoma hederacea and Alliaria petiolata, halophytes, spring geophytes) by investigating their reproductive potential, phenotypic plasticity, ecophysiology, co-existence and persistence. Recently we became interested in the ecological roles of selected animal species (e.g. leaf miner Cheliosia fasciata).

Experimental ecology – in the laboratory we study competition between insects and adaptations to new sources of food; we perform various kinds of experiments in the field and lab to study the ecology of seeds (e.g. germination persistence, survival, dispersal), check the effects of abiotic and biotic stress on plants (anatomical, morphological, physiological, functional responses) and carry out some molecular studies.
Theory in ecology – we are interested in understanding ecological processes behind the co-existence mechanisms and biodiversity patterns with mathematical models.
