Freshwater algae of Kunashiri Island, the South Kuriles

Comparative sensitivity of freshwater algae to atrazine.

Freshwater Algae: Identification and Use as Bioindicators

Algae are widely present in freshwater environments, such as lakes and rivers, where they are typically present as micro-organisms – visible only with the aid of a light microscope. Although relatively inconspicuous, they have a major importance in the freshwater environment, both in terms of fundamental ecology and in relation to human use of natural resources. This book considers the diversit...

Bioactivity potential of some marine algae from south of Iran

Algae are composed of a diverse group of various aquatic organisms. Secondary or primary metabolites from these organisms may be potential bioactive compounds of interest for use in the development of new pharmaceutical agents. In this research, four species of marine algae, Ulva lactuca, Padina pavonica, Colpomenia sinuosa and Cystoseira myrica, isolated from Persian Gulf coasts were evaluated...

South Island kokako search, Abut Head, South Island

This document describes a search for South Island kokako, carried out in September and November 1997, following a detailed report of presumed kokako seen recently by Barry Donovan atAbut Head, South Westland. Two sites where possible sightings were made were investigated intensively, while a more general search was carried out at other parts of Abut Head. Search methods involved broadcasting an...

Uptake and Bioconcentration of Atrazine by Selected Freshwater Algae

Atrazine bioconcentration and uptake were determined for eight freshwater green algae and diatoms. Atrazine uptake was extremely rapid in all species examined, with nearly 90% of total uptake occurring within the first hour of exposure. Within each division, different species had different bioconcentration capacities, although the accumulation of atrazine was consistently higher in green algae ...
