Currently, there is a worldwide growing interest in the occurrence and diversity of fungi and their secondary metabolites in aquatic systems, especially concerning their role in water quality and human health. However, this concern is hampered by the scant information that is available in the literature about aquatic fungi and how they affect water quality. There are only few published reports ...

b t T a e t n fi b This paper demonstrates the necessity to consider lants as an essential and interactive component of iological control practices. Plants not only possess irect chemical and morphological defenses against erbivores but also benefit from indirect defenses rovided by parasitoids and predators, which use erbivores as hosts or prey. Plants play an active role n the interplay betwe...

Arbuscular mycorrhizal fungi (AMF) are a group of obligate plant symbionts which can promote plant nutrition. AMF communities are diverse, but the factors which control their assembly in space and time remain unclear. In this study, the contributions of geographical distance, environmental heterogeneity and time in shaping AMF communities associated with Miscanthus giganteus (a perennial grass ...

Negative population feedbacks mediated by natural enemies can promote species coexistence at the community scale through disproportionate mortality of numerically dominant (common) tree species. Simultaneously, associations with arbuscular mycorrhizal fungi (AMF) can result in positive effects on tree populations. Coupling data on seedling foliar damage from herbivores and pathogens and DNA seq...

The extents of functional surfaces (villi, microvilli) have been estimated at different longitudinal sites, and in the entire small intestine, for three species of bats belonging to two feeding groups: insect- and fruit-eaters. In all species, surface areas and other structural quantities tended to be greatest at more cranial sites and to decline caudally. The entomophagous bat (Miniopterus inf...

Development and reproductive potential of the Coccinella septempunctata L. (CSL) was conducted under laboratory conditions to determine its fecundity and longevity on natural and artificial diets. Tests were made on laboratory rearing materials and all development stages were carefully recorded. Success ratios in these experiments were a matter of logistic and synchronization of these life cycl...

2 Institute of Ecology, Nature Research Centre, Akademijos 2, LT-08412 Vilnius, Lithuania Solitary cavity-nesting Hymenoptera constitute a group of important bioindicators of terrestrial habitats. Some of them, like caterpillar-hunting potter wasp Ancistrocerus trifasciatus (Hymenoptera: Vespidae: Eumeninae), are quite abundant in both continuous and fragmented habitats and might be a promising...

Understanding plant-microbe relationships can be important for developing management strategies for invasive plants, particularly when these relationships interact with underlying variables, such as habitat type and seedbank density, to mediate control efforts. In a field study located in California, USA, we investigated how soil microbial communities differ across the invasion front of Taeniat...

A computer model of the fungal colony that grew consuming limited amount of nutrient with three control parameters, growth rate, and nutrient level and diffusion, was constructed to make a basic morphology diagram of mycelial colony. To apply the diagram with those parameters to the mycelial growth of Aspergillus nidulans wild and mutant strains, the relation between the colony expansion and th...

Priority effects - the impact of a species' arrival on subsequent community development - have been shown to influence species composition in many organisms. Whether priority effects among arbuscular mycorrhizal fungi (AMF) structure fungal root communities is not well understood. Here, we investigated whether priority effects influence the success of two closely related AMF species (Rhizophagu...
