Determinants of local plant abundance relative importance of fitness and stabilizing niche differences (GA15-09119S)

Coexistence theory views plant species abundance patterns as a result with increasing species relative abundance, maintain coexistence of species with different among species in their fitness and stabilization for their local ab...

Long-time changes in population of cereal aphids and their predator (GA522/05/0765)

Long-time series of observation of insect abundance of one species could by weather. We have a parallel record of variation in abundance of insect predator (seven the causes of dramatic decrease of abundance of both prey an...

Does phenotypic plasticity of plant species affect their regional abundance? (GAP505/12/1007)

One of the ultimate goals of ecology is to explain patterns of species abundance. While we know that abundance is affected by some plant traits (such as growth rate), there is virtually no information whether species abundance

Agroecological factors affecting abundance of cereal pests (GA521/01/0626)

The project investigates factors of host plant quality important for determining aphid and cereal leaf beetle abundance in production stands of small grain cereals. The underlying conceptual model assumes that host plant quality determines p...

What do the most abundant oceanic protistan proteins actually do? (GX23-06479X)

Protists represent the most speciose and abundant eukaryotes of the ocean some of them represent the most abundant sequences in the ocean. Using advanced bioinformatics, we analysed millions of predicted proteins, to identify the mo...

Factors determining the structure of communities of aphid predators and their impact on aphid abundance in cereal stands (GA522/08/1300)

Predators affect the population development of aphids in cereal stands but the magnitude of their effect (compared to the effects of aphid migration, intraspecific competition and  host plant quality) is not easy to establish. In this project we test...
