Novel Sources of Tolerance to Aluminium Toxicity in Wild ( and ) Collections.

In acid soils, the toxic form of aluminium, Al, significantly inhibits root growth and elongation, leading to less water and nutrient uptake. Previous research had shown differential Al toxicity tolerance among cultivated L. (chickpea); however, the potential for developing tolerant cultivars is limited by the narrow genetic diversity of cultivated chickpeas.

Constraints upon the response of fish and crayfish to environmental flow releases in a regulated headwater stream network.

In dry climate zones, headwater streams are often regulated for water extraction causing intermittency in perennial streams and prolonged drying in intermittent streams. Regulation thereby reduces aquatic habitat downstream of weirs that also form barriers to migration by stream fauna. Environmental flow releases may restore streamflow in rivers, but are rarely applied to headwaters.
