Introduction
My area of interest is conservation biology and (aquatic) ecology. My main project is focusing on analysing food webs. I am interested in comparing different (topological, dynamical, and trait-based) approaches to estimate the impact of functional groups on each other in aquatic food webs. Previously, In my PhD project, I studied poorly known, endangered plant species, and developed ex-situ conservation protocols for the most vulnerable ones.

Article
Using network analysis for making predictions about food web dynamics is one of the major challenges in systems ecology. Since there are several notoriously difficult methodological problems with food webs, only a comparative perspective can help. We study a standard database for trophic flow networks and analyse the correlation between structure a...
Article
Full-text available
Species are embedded in a web of intricate trophic interactions. Understanding the functional role of species in food webs is of fundamental interests. This is related to food web position, so positional similarity may provide information about functional overlap. Defining and quantifying similar trophic functioning can be addressed in different wa...
Article
Full-text available
We briefly discuss the relationship between the biological knowledge and the methodological issues related to trait-based ecological analyses. We provide illustrative examples and argue that the biological novelty of trait-based research is generally less than expected - while new information is mostly coming from data management and methodology.
Article
Full-text available
As climate change is forcing plant species to migrate northward and upward, it is important to know how species' vegetative traits and reproductive success vary along different climatic conditions. We aimed to examine the impact of elevation on the morphological and reproductive characteristics of Cephalanthera rubra in four different altitudes in...
Article
Full-text available
Networks of trophic interactions provide a lot of information on the functioning of marine ecosystems. Beyond feeding habits, three additional traits (mobility, size, and habitat) of various organisms can complement this trophic view. The combination of traits and food web positions are studied here on a large food web database. The aim is a better...
Article
Full-text available
This study was carried out to determine the effect of arsenic on tomato and cabbage cultivated in sand, sandy silt, and silt soil, and irrigated with water containing arsenic at concentrations 0.05 and 0.2 mg/L. Increasing arsenic in irrigation water did not affect the photosynthetic machinery. The chlorophyll content index increased in case of all...
Article
Full-text available
Contrasting reductionistic versus holistic views, it is a general question whether adding the parts equals the sum. In the time of multiple drivers of anthropogenic change, it is a crucial issue, and better understanding additivity is critical for strategy and management. More particular research questions ask what are the community effects of the...
Chapter
Benthic ecosystems along the north-central Chilean coast are characterised by the presence of kelp forests, considered as ecosystem engineer or niche constructor organisms. Despite their essential ecological role, in the last years kelp forests have been heavily exploited and disturbed by artisanal fishing, inducing drastic changes in such benthic...

Accumulation of iodine by potato ( Solanum tuberosum L.) and carrot ( Daucus carota L. var. sativus ) plants cultivated on different soils (sand, sandy silt, and silt) using irrigation water containing iodine at concentrations of 0.1 and 0.5 mg/L was investigated. In the edible organs of potato and carrot control plants grown on sand, sandy silt, a...

Iodine uptake and translocation was studied in cabbage and tomato cultivated on different soil types (sand, sandy silt, silt) by applying irrigation water containing iodine at concentrations of 0.1 and 0.5 mg/L. Iodine treatment at the concentrations applied did not significantly influence the photosynthetic efficiency and chlorophyll concentration...

In community ecology, network perspective can be useful in answering many different questions: besides describing and comparing different systems, it is often used to quantify the relative importance of functional groups and to identify keystone species within ecosystems. Despite the fact that food webs seem to be strictly hierarchical, food web m...
Article
Food webs dynamically react to perturbations and it is an open question how additive are the effects of single-species perturbations. Network structure may have topological constraints on additivity and this influences community response. Better understanding the relationships between single-species and multi-species perturbations can be useful for...

HIGHLIGHTS: ● Maximum sustainable yield (MSY) should be assessed in multi-species context ● Single-species and pairwise disturbances on food web simulations ● We determine which pairs of species show non-additive community effects when disturbed ● We study the topological relationship of these species pairs ● Perturbing pairs of species that are ei...

One of the most important aims of conservation ecology is to quantify the relative importance of species and find keystone species within ecosystems. A possible approach for this problem is the network perspective which focuses on the structure and interactions of community webs and is able to define the positional importance of species with the he...

Kutatásunk egy Magyarországon erősen megfogyatkozott, fokozottan védett és szőcei állományának ex-situ szaporítására javasolt növény, a tőzegeper (Comarum palustre L.) sza-porítását tűzte ki célul. A terület bejárása, az irodalmi adatok és saját cönológiai felvételeink alapján megállapítottuk, hogy a faj a szőcei lápréten számára előnytelen, invázi...

A kunsági bükköny Magyarország egyik legveszélyeztetettebb növényfaja. Kisméretű, izolált populációi sérülékenyek, élőhelyein pedig egyre erősödik az emberi zavarás. Emellett kevés az ismeret a faj életmenetéről és biológiájáról, ami megnehezíti védelmét. Hazánkban, a védelem ellenére erősen csökken az állomány, így ex-situ védelemre javasolták a f...

Project
The aim is to investigate the measure of (non-)additivity of the effects of two simultaneously perturbed species on the ecosystem. This effect is measured by the so called community response index, which is the sum of the biomass-changes of the non-perturbed species of the ecosystem. If the effects of the single-species perturbations are additive, this means, that the combined effect of the simultaneously perturbed species is simply the sum of the single-species effects; non-additivity means, that the combined effect is less (antagonistic) or greater (synergistic) than the sum of the single-species cases.

The 'Fresh Blood for Fresh Water' is a community meeting of early-career limnologists, representing not just new incomers to the field, but also those who still (or forever) feel themselves “fresh blood”. The conference aims to provide a friendly atmosphere to meet, to present the new results and exchange ideas with other young researchers. In 2019, young researchers of the MTA Centre for Ecological Research welcome the conference in Tihany, Hungary, at a beautiful venue. The program will include various sessions for talks and posters, four plenary talks by early-career group leaders with outstanding achievements in their fields and workshops covering both theory and practice given by senior and advanced junior scientists. Several social events will complete the scientific program. For details, please check our website: http://fbfw2019.okologia.mta.hu/
