Allelopathy is an important ecological phenomenon influencing ecosystem dynamics. Currently, it has gained attention due to the potential applications of allelochemicals in agriculture. Allelopathic interactions have been reported in ecological relationships between plants and microorganisms, and between species of each group. These studies have been relatively descriptive, however, without interconnected...
The study evaluated shape of the foramen magnum (FM) in dog with regard to its constitutional type (small, medium and large breeds) and morphotype (brachycephalic, mesaticephalic and dolichocephalic dogs). We used multi-slice CT scanner to examine occipital area of 138 purebreds dogs. Two studied groups could be distinguished–living animals undergoing standard diagnostic CT procedure (n = 47) and...
Peat bogs play key roles in preserving the stability of ecological relationships, but are some of the fastest disappearing and most endangered ecosystems in Europe. The aims of this study were: (1) to compare the distribution, species richness, diversity, and density of rotifers in microhabitats of a raised bog; and (2) to verify the hypothesis that rotifer density and species composition are dependent...
Solidago minuta L., a high-mountain species of the Solidago virgaurea group, occurs on some European mountain chains but it has been suggested that morphological differentiation of S. minuta is controversial due to the existence a wide range of morphologically intermediate plants between lowland S. virgaurea s.s. and high-mountain S. minuta. However, the recent study of this group revealed that both...
From 1997 until 2014 we carried out a GIS-based systematic mapping of mosquito breeding sites on a 2,690 km2 area in the important touristic regions of Hungary. During the process of data collection of the mosquito fauna, 42,547 adults of 26 species and 34,409 larvae of 28 species were collected. The ecological characteristics of the breeding sites were recorded by means of 4,543 samples. We have...
The anatomical structure of the leaf and stem of nine Micromeria species from the Balkan Peninsula was investigated with the aim to establish the adaptive characteristics and traits that could be useful in the identification of species and subgeneric classification. The species included in the anatomical analysis were: Micromeria albanica (Griseb. ex K. Malý) Šilić, M. thymifolia (Scop.) Fritch, M. pulegium...
Numerous studies have investigated the nest-site characteristics and selection of bird species, because these features often play a determining role in bird breeding success. In recent years researchers focused on urban environments as a source of novel conditions which provide breeding opportunities for species that are able to survive in human-altered environments. Although thrushes Turdus spp....
Antioxidants can reduce the occurrence of long-term damages, caused by free radicals. In this study, we aimed to evaluate the effects of CuO nanoparticles and hydroalcoholic extracts of Berberis vulgaris, Descurainia sophia and Silybum marianum on catalase, glutathione peroxidase, and malondialdehyde concentrations in male diabetic rats. In case 50 Wistar rats (250–350 g) were divided in ten groups...
An in situ experiment to investigate periphytic community development was conducted on an artificial substrate (glass slides) in a Danube floodplain lake in Croatia. The main aim of the research was to analyze the structure of the ciliate community (Ciliophora, Protozoa) in the periphyton. We wanted to investigate how biotic and abiotic factors change and influence the ciliate community, reflecting...
Desert annual plant species are valuable pasture forage and sources for restoration of degraded pastures. Examining the impact of environmental stresses on genetic diversity and population structure can identify species populations suitable for habitat restoration. We examined allozyme diversity and population structure of two annual species, haloxerophyte Salsola incanescens and xero-halophyte S. paulsenii...
The EST3 gene of Saccharomyces cerevisiae encodes one of the essential subunits of telomerase enzyme. Expression of the EST3 gene is regulated at the translation level by +1 programmed ribosomal frameshift (PRF). It is known that physiological stress affects telomere length. In this study, we have investigated the effects of different types of stresses and stress activated protein kinases on the frameshift...
A highly alkaline pectin lyase (PNL) produced by Fusarium lateritum MTCC 8794 using solid-state fermentation was purified and biochemically characterized. The enzyme was purified to homogeneity by comparatively simple method involving ammonium sulfate precipitation and cation exchange chromatography resulting in a final purification fold of 5.5 with specific activity of 1.9 U/mg and yield of 3.42%...
Urinary tract infections (UTIs) are one of the most frequent infections in elderly people. The majority of infections is caused by uropathogenic E. coli. These strains contain a broad spectrum of virulence factors and are able to overcome defense barriers and colonize host organism. Population of elderly individuals has been growing globally and for that reason it is possible to expect a rise of UTIs...
The mating disruption technique using Checkmate® VMB-XL pheromone dispensers, in combination with imidacloprid-based insecticide treatments through drip irrigation, was tested against vine mealybug in Tunisian vineyards for the first time in the South Mediterranean area. The number of male vine mealybugs caught in traps of mating disruption (MD) plots was significantly lower than that of Non-MD plots,...
This study evaluated the temporal and bathymetric distribution of the speckled swimming crab Arenaeus cribrarius from coastal waters of southern Brazil. Monthly samples were taken at five distinct depths throughout one year in the adjacent area from Babitonga Bay, Southern Brazil. Data on environmental conditions (temperature, salinity, granulometry and organic matter) were collected and their association...
Proline, 24-epibrassinolide and diphenylene iodonium are few of the novel antioxidant molecules, involved in growth regulation and abiotic stress tolerance of plants. However, these are scarcely explored in relation to their role in arsenic stress tolerance. Therefore, present study was designed to investigate the involvement of proline, 24-epibrassinolide and diphenylene iodonium in conferring tolerance...
The present investigation was made to study the influence of hormones on leaf regeneration and mineral acquisition (Ca, K, Mg, Bo, Cd, Cr, Ni, Fe and Se) in Jatropha curcas using Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The method employed direct induction of shoot buds from the leaves of four different genotypes (CSM-1, CSM-2, CSM-3, CSM-4) using Murashige & Skoog (MS)...
In the crustacean Branchipus schaefferi cercopods are brightly coloured caudal rami at the end of the abdomen. The specific life environment of B. schaefferi (highly turbid puddles) may suggest that besides their mechanical function, cercopods may also play an ornamental role to attract a potential mate. We performed standardized major axis regression analyses of cercopod length against body length...
Aphid species Brachycaudus divaricatae Shaposhnikov, 1956, originally described from Turkmenistan and earlier known from the Middle East and Eastern Europe only, is a successful invader to Central Europe. Its principal winter host, Prunus cerasifera, was originally distributed in Central Asia, Near East, and South Eastern Europe. Now it is common in Eastern and Central Europe. Brachycaudus divaricatae...
The largest rivers in Europe are under strong human pressure, resulting in habitat changes and consequently in structural changes in the quantitative and qualitative composition of fauna assemblages. The aim of this study was to identify the taxonomic structure of leech assemblages and the main environmental factors influencing their distribution pattern on a 306 km stretch of the Oder River encompassing...
