insects with over 30,000 aquatic species are known as very successful arthropods in freshwater habitats. some of them are applied as biological indicators for water quality control, as well as the main food supply for fishes and amphibians. the faunistic studies are the basic step in entomological researches; the current study was carried out emphasizing on the fauna of aquatic insects in karaj...

During the period of 2014-2016 we studied the food relationship of free living ciliates of Agzybir Lake. In all 162 species were found, 12 of them were marked for the first time the Caucasus fauna. The ciliates, differs for feeding process, were combined of five trophic groups (algophages, bacteriophages, nonselective omnivorous species, predators and histophages). The food relationship between...

Invertebrates and plants are among the most ubiquitous and abundant macroscopic organisms in aquatic ecosystems; they dominate most habitats in both diversity and biomass and play central roles in aquatic food webs. Plants regulate and create habitats for a wide array of organisms (Cooke et al. 2005). Snail grazing and bivalve filtering profoundly alter habitats and communities (Harvey and Hill...

128 Semi-aquatic wildlife species have been important sentinels of environmental health and remain important biomonitors concerning emerging contaminant issues. The semi-aquatic wildlife of the Laurentian Great Lakes (LGL) has led the way in this regard and continues to do so. This is because the LGL and associated land mass possess a set of unique characteristics that make it an ideal laborato...

Wolbachia is a genus of intracellular bacteria typically found within the reproductive systems of insects that manipulates those systems of their hosts. While current estimates of Wolbachia incidence suggest that it infects approximately half of all arthropod species, these estimates are based almost entirely on terrestrial insects. No systematic survey of Wolbachia in aquatic insects has been ...

JAVMA, Vol 231, No. 6, September 15, 2007 F medicine has been a relatively small discipline of veterinary attention in the past because of many factors, the most important of which is the perceived value of pet and ornamental fish. As more people invest in expensive species, such as koi and various reef species, the demand to provide a higher level of care for these animals is increasing. This ...

BACKGROUND Habitat loss and overexploitation are among the primary factors threatening populations of many mammal species. Recently, aquatic mammals have been highlighted as particularly vulnerable. Here we test (1) if aquatic mammals emerge as more phylogenetically urgent conservation priorities than their terrestrial relatives, and (2) if high priority species are receiving sufficient conserv...

A list of the most common plants that form phytotelmata and their associated coleopterans (aquatic, semi-aquatic and terrestrial) from the northeastern subtropical and temperate area of Argentina, South America with biological and behavioral observations is presented in this study. Species of Poaceae (n = 3), Bromeliaceae (5), Apiaceae (6), Araceae (2), Urticaceae (1), Marantaceae (1), Arecacea...

Becker et al. (1) showed a strong effect of habitat split on the richness of species with aquatic larvae but no effect on the richness of species with terrestrial development, both when habitat split was analyzed alone in linear regressions and when it was analyzed together with habitat loss and fragmentation in more complex path analyses. Cannatella (2) argues that if species with aquatic larv...
