The effects of physiological integration on clonal plants growing in aquatic and terrestrial habitats have been extensively studied, but little is known about the role in the extension of amphibious clonal plants in the heterogeneous aquatic-terrestrial ecotones, especially when the water environments are polluted by heavy metals. Ramets of the amphibious clonal herb Alternanthera philoxeroides...

all aquatic organisms are directly or indirectly affected by the physical characteristics of their environment, especially the chemical composition of the water. the high concentration levels, damage tissues and interfere with the normal growth and proliferation. the aim of this research was to investigation acute toxicity of znso4 and cucl2 to gambusia holbrooki by static bioassays at differen...

The striking similarity between aquatic feeding behaviors in fishes and tetrapods and terrestrial prey transports in tetrapods and their contrasts to terrestrial tongue projection kinematics have led to a general hypothesis that terrestrial prey capture evolved from terrestrial prey transport, which, in turn, evolved from aquatic feeding behavior. This hypothesis is examined in Salamandra salam...

Stable isotope and fatty acid signatures of biomaterials can provide important information about the dietary niche of animals. Stable isotope and fatty acid signatures differ between aquatic and terrestrial food webs, and therefore can be used to assess the aquatic and terrestrial contributions to the diets of species. We studied faecal samples of three co-occurring bat species with known diffe...

Due to the rapid advent in genomics technologies and attention to ecological risk assessment, the term "ecotoxicogenomics" has recently emerged to describe integration of omics studies (i.e., transcriptomics, proteomics, metabolomics, and epigenomics) into ecotoxicological fields. Ecotoxicogenomics is defined as study of an entire set of genes or proteins expression in ecological organisms to p...

textile effluents contain different kinds of chemical dyes and many mutagenic and carcinogenic substances. discharge of these effluents into terrestrial and aquatic ecosystems causes harmful effects. in this research, decolorization of a textile effluent by nineteen different strains of fungi was investigated. removal activity of dyes was in order of   aspergillus > rhizopus > fuzarium > penici...

The diversity and distribution of the rotifers family Notommatidae was studied in the northwest, the south and the southwest of Iran. In total, 29 species were identified, of which, 25 are new records for the country. New records include the following species: Cephalodella forficata, C. cf. mus, C. vittata, C. ventripes, C. lepida, C. inquilina, C. gibboides, C. tincaformis , C. obvia, C. stere...
