“…Analogous to the law of tolerance (Schwerdfeger, 1977;Shelford, 1931) as interpreted by Pörtner (2001Pörtner ( , 2002a, the CO2 profiles characterise the rise in metabolic rate in both species across their range of aerobic capacity (above 30°C), culminating in a maximum metabolic rate VCO∑max corresponding to a temperature here termed the TMetMax (equivalent to Pörtner's TpII -upper pejus temperature). Beyond the TMetMax (=TpII) increasing temperatures cause the onset of a progressive decrease in metabolic rate.…”

declined with declining oxygen concentration, this was not the case in the beetle. Efficient oxygen delivery via a tracheal system makes oxygen limitation of thermal tolerance, at a whole organism level, unlikely in insects. By contrast, oxygen limitation of thermal tolerances is expected to apply to species, like the isopod, in which the circulatory system contributes significantly to oxygen delivery. Because insects dominate terrestrial systems, oxygen limitation of thermal tolerance cannot be considered pervasive in this habitat, although it is a characteristic of marine species.

“…where a is the number of elements in set A, b is the number of elements in set B and J is the number of common elements of sets A and B [16]. The diversity index was calculated from the Margalef formula: d = s-1/ logN, where d is the index of diversity, s is the number of families represented at a given site, and N is the mean density of fauna at the site expressed per m 2 [16].…”

Analysis of benthic macroinvertebrate communities from the Lower sections of Large river in relation to different environmental factors

et al. 2014

The aim of this study was to make a comparative analysis of macrozoobenthos composition at different sites at selected sections of lower the Odra River with relation to different physicochemical factors. The observations were made on the lower section of Odra River at five study sites: two of them were localized in the main channel, one in the left branch of river, another one in the channel carrying post-cooling water from Dolna Odra power plant, and the last one was in the channel connecting both branches of Odra River. At all sites, 26 taxa were found representing by: Bivalvia, Gastropoda, Oligochaeta, Hirudinea, Malacostraca and Insecta. The greatest biodiversity and the highest abundance of zoobenthos organisms were noted in the channel joining the two branches of the river, site 5, characterised by the lowest water flow rates and the densest coverage of the macrophytes at the bottom. Temperature was the sole parameter to be studied that affected the composition of benthic invertebrates. A clearly negative impact of temperature on the diversity of invertebrates was observed only in the channel with post-cooling water discharged from the power plant.
