Význam interakcií medzi ektoparazitmi pre prenos vektormi-prenášaných patogénov
The role of ectoparasite-ectoparasite interactions in the transmission of vector-borne parasites
Program: VEGA
Project leader: Mgr. Václav Radovan, PhD.
Annotation: One of the biggest challenges faced by ecologists is to understand how and to what extent interspecific interactions within and between different guilds influence community structure, abundance of specific species or biodiversity of organisms of interest such as pathogens. In spite of a general acceptance of the existence of such a complex system, most ecological interactions are studied in relative isolation. The goal of this project is to see how the interactions between a certain host and a certain vector-borne parasite are affected by the complexity of ectoparasite-ectoparasite interactions. We specifically aim to establish if the interactions among multiple blood-feeding dipteran ectoparasites can influence the susceptibility of an avian host to some of the ectoparasites and/or pathogens that they vector. Namely, we plan to reveal if host susceptibility to haemosporidians can be mediated by 1) ectoparasite-ectoparasite interference or 2) modulation of host immunity by background ectoparasite pressure.

reprodukcia – Reprodukčné stratégie vo vzťahu k akustickým parametrom a migračným stratégiám: štúdie na trsteniarikovi bahennom (Acrocephalus scirpaceus) a strakošovi kolesárovi (Lanius minor).
Reproductive strategies and relation to acoustics and migration: case studies on Reed Warbler and Lesser Grey Shrike
Program: VEGA
Project leader: RNDr. Darolová Alžbeta, CSc.
Annotation: Song of passerines have several functions, like territory defense and mate attraction. By using of reproducedsong of higher and lower quality in the Reed Warbler we will simulate occupied territories by males of differentquality. We will determine the male strategy of territory choice affected by simulating quality of neighbor song, thefemale mate choice in relation to quality of neighbor song and evaluate the maternal investment of females intoeggs in terms of clutch size, egg yolk testosterone and egg white lysozyme, in dependence on quality of neighborsong. Long-distance migrant songbirds are among the most endangered species. Their migration strategies arealmost unknown and their relation to reproductive strategy, population trend and endangering factors is being notexplained sufficiently. Using geolocators we will study the migration strategies and routes of selected individualsof the Lesser Grey Shrike and analyze their breeding success as well local and global factors of endangerement.

Oribatocenózy urbánneho prostredia
Oribatid mite communities of urban ecosystems
Program: VEGA
Project leader: Mgr. Mangová Barbara , PhD.
Annotation: The human impact on ecosystems and communities of different organisms is highly actual topic. Mankind is changing its environment continuously and is adapting it to its needs without any regard to other biota. By indirectimpact we often unknowingly decrease diversity of all communities (as plants as animal). This way also communities of small soil arthropods are affected that play a serious role in nutrient cycling due to cutting of fallenleafs. This project will be focused on oribatid mite communities in urban habitats and other biotops affected byhuman impact. Oribatids are soil mites and for their communities it typical high diversity in natural ecosystems.This diversity decreases withincreasing human impact and it also changes species composition of thecommunity. Using structure of orbatid mites community we want to define differences between different ways how to care for “green parts” of the city.
