By combining morphology, ecology, biology, and biogeography with the available molecular (sequence variation of the entire mitochondrial cytochrome b gene; cyt-b) and karyology data, the taxonomy of several species of the Rutilus complex inhabiting southern Europe is revised. Rutilus stoumboudae, new species, is described from Lake Volvi, Greece. It differs from Rutilus rutilus in possessing mo...

The effects of predation on water-filled treehole communities in North Carolina were examined using mesocosm experiments and observations in natural treeholes. The presence of the predator Toxorhynchites rutilus and leaf litter abundance were manipulated in mesocosms to examine interactions between resources and predation. Long-term examination of interactions in unmanipulated treeholes provide...

The 1st recorded capture of Toxorhynchites rutilus in Massachusetts, USA, is reported. This capture represents the northernmost record of Tx. rutilus. The implications of this capture are discussed in the context of range expansion, evolution, and climatic change.

Aspidogaster limacoides Diesing, 1834 was identified in two specimens of roach (Rutilus rutilus L.) from middle Odra River (Lower Silesia, SW Poland). As the species is new to the Polish parasitofauna, a description, measurements and figure are presented.

Artificially cultivating Chroogomphus rutilus is too inefficient to be commercially feasible. Furthermore, isolating C. rutilus mycelia in the wild is difficult. Thus, it is important to determine the natural habitat of its fruiting body. This study focused on the ecology of the C. rutilus habitat to isolate and classify beneficial microorganisms that could affect its growth, which could be use...

The coexistence of competing species relies on niche partitioning. Competitive exclusion is likely inevitable at high niche overlap, but such divide between competitors may be bridged if environmental circumstances displace competitor niches to enhance partitioning. Foraging-niche dimension can be influenced by environmental characteristics, and if competitors react differently to such conditio...

Protein synthesis by a rabbit reticulocyte lysate is inhibited by the haemagglutinating lectins from Momordica charantia and Crotalaria juncea seeds and from the roe of Rutilus rutilus, and by a commercial preparation of the mitogenic lectin from Phytolacca americana. The haemagglutinins from the seeds of Ricinus communis and of Vicia cracca acquired inhibitory activity after their reduction wi...
