Flower strips can be an important component of integrated pest management and contribute to reducing pressure on agroecosystems, which is why they are increasingly implemented as part agri-environmental programs. They used a multifunctional agronomic tool because prevent the decline species diversity in agroecosystem increase functional biodiversity, prerequisite for provision ecosystem services, such pollination natural control. Research highlights great potential multifunctionality flower...

Flower strips (FSs) are an effective way to support the sustainable development of agricultural land. Properly managed FS on fields provide stable habitats for local arthropod populations, but over years, it can be colonized by plants from soil seed bank and then become a nuisance surrounding crops. The aim this study was assess botanical composition in one year after establishment analyze population Carabidae, most which predatory. Inventory flowering situ made regularly beginning June end...

We studied the effect of flooding on a carabid community inhabiting grassland in large river valley (W Poland).We used pitfall-traps to catch beetles from April November 1999-2001.Some samples collected were preceded by floods during collecting period, which enabled us evaluate effects species composition and abundance.We 17,722 individuals belonging 108 species.The number per sample differed between plots showed nonlinear decrease over time, spring autumn.Carabids more abundant after than...

Classic theories on assembly rules and food-web structure are species-centered, so they largely ignore intraspecific variation. Intraspecific trophic variation, however, might be of key importance in understanding community organization. Here we study the variability isotopic niche spaces ground beetles its consequences for beetle assembly. Stable isotopes ratios (δ13C δ15N) were measured 1156 specimens carabids belonging to 59 species inhabiting 20 island two mainland sites Masuria Lakeland...

Biological inventory is a crucial activity in life sciences field research. However, it sometimes time-consuming and laborious to take representative samplings of communities, especially the case invertebrates. In this paper, we address issue sampling efficiency its influence on obtained results. As study system, used data epigeic carabid beetles (Carabidae) collected 1999–2001 Warta River valley western Poland. We trapped total 17,722 individuals belonging 108 species. due rarefaction...

Neutral theory focuses on random dispersal and species equivalence, challenges views the ecological importance of life history traits habitat properties in explaining community assembly spatial distribution species. Ground beetles are a popular model taxon to test predictions contrasting macroecological theories. Here we investigate effects occurrence structure 71 carabid beetle inhabiting 15 lake islands NE Poland. Island properties, particularly area quality, were positively linked...

Abstract A growing body of evidence suggests trophic generalism (feeding on resources from more than one level and/or different the same level) is a widespread feature among ground beetles (Coleoptera: Carabidae). However, it remains unclear whether applies to single individuals, at intrapopulation or interpopulation level. Here we present stable isotope data (δ 15 N, δ 13 C) seven common European carabid species an archipelago 18 lake islands in northeastern Poland. We found strong...

Ecological intensification of agriculture (e.g., with the use wildflower strips) is being currently discussed as a mean for gaining high yields, preserving biodiversity farmland. The aim this study was to assess efficiency annual strips (WFSs) established in rye field (RF) (1) increasing species richness and abundance terms beneficial arthropod groups (carabids, ground spiders, plant butterflies, insect pollinators plant-dwelling predators), (2) decreasing pests, (3) damages crop, (4) yield....

As movement is expensive in terms of energy required, mobile animals might have to utilize more rich resources than less animals.As are possibly effective foragers we hypothesize a positive correlation between mobility and trophic niche width.We address this link using information on the level 35 winged, wingless wing dimorphic species ground beetles studied 18 lake islands at two mainland sites northern Poland.Trophic analyses stable isotope values (δ 15 N, δ 13 C) revealed that winged...

state of the fi eld cricket population seems to be visible in Germany and Poland.Grein (2000, 2005 after Hochkirch et al., 2007) states that only ten populations are left Lower Saxony one west Weser River.At same latitude, but 400 km east Poland, species is still very common widely distributed throughout whole country (Bazyluk & Liana, 1990, 2000).This contrast between Europe may result differences land-use man-

New data concerning the occurrence of pleasing fungus beetles (Coleoptera: Erotylidae) in Poland are given, with a focus on rare and difficult to identify Central European taxa. Cryptophilus cf. integer (Heer) (Cryptophilinae) is reported from Polish territory for first time based adult larval specimens collected Wielkopolska-Kujawy Lowland. Identification problems species introduced Europe discussed. Triplax carpathica Reitter (Erotylinae) recorded Białowieża Primeval Forest, which known...

Abstract Contrasting trophic theories of island biogeography try to link spatial patterns in species distribution and richness with dietary preferences, arguing that the turnover among habitat patches changes rank causing a systematic change proportion plants, herbivores, predators across habitats different size. Here we test these predictions using quantitative surveys spiders, herbivores as well omnivorous predatory ground beetles on undisturbed Polish lake islands. We found decreased...
