Toward improved assessment of freshwater salinization as a benthic macroinvertebrate stressor
… Salt pollution can cause adverse effects to aquatic biodiversity, ecosystem function, ecosystem services, and human health. In many regions of the world, and in coal-mining-influenced streams of the temperate forests of Appalachia USA, specific conductance (SC), a surrogate measure for the …

Vocalizing Behavior in Killer Whales (Orcinus orca) – an Evolutionary Account
In this thesis, we compare human language, as defined by Noam Chomsky in his biolinguistic account of language, with killer whale (Orcinus orca) vocalizations and what we call the orca vocalization and orca symbolic vocalization systems. We postulate hypothetical orca counterparts of the elements …

Biological diversity of epibenthic invertebrates in relation to environmental factors in lava caves around Lake Mývatn (N-E Iceland)
Biodiversity, and its understanding and maintenance, are nowadays concerns in many fields of sciences. In freshwater, epibenthic invertebrates are important for their environment as consumers at intermediate trophic level and as food resources for other organisms. Their sensitivity to environmental …

A method of detecting reaction to environmental influence by recording circadian activity, using the flagfish Jordanella floridae
… a means of detecting the reaction of aquatic vertebrates to environmental change by recording behavioral patterns within the diurnal activity. An apparatus measuring the activity of Jordanella floridae, Goode and Bean, using a photoelectric sensor system is described. Individual …
