Non-harmonic covariation among life-history traits in amphipods (Hyalella azteca) and crayfish (Orconectes virilis) in Canadian boreal lakes

Principal components analysis was used to determine the degree of covariance among life-history traits in eight populations of the amphipod Hyalella azteca and four populations of the crayfish Orconectes virilis inhabiting Canadian boreal lakes. Assumptions of tightly coupled traits which vary unidimensionally as a single fixed unit or "tactic" are untenable for these organisms. Instead,...

Penicillium abundance and diversity patterns associated with cashew plantations in coastal sand dunes, Odisha, India

The abundance and diversity of Penicillium species were studied from soils in coastal sand dunes of Odisha, India for a period of two years covering three distinct seasons. A total of 41 species were enumerated, of which the surface soil of the site without vegetation had 23 species while its sub-surface soil contained 24 species. In the site with Anacardium occidentale (cashew) plantation, the...

Physico-chemical characterization of seed oil from Jatropha curcas L. genetic resources

Studies were carried out to assess seed physico-chemical properties of Jatropha curcas genetic resources. Twenty five seed sources of J. curcas investigated in the current study exhibited wide variation for seed physio-chemical properties. The chemical properties of seed sources indicated superiority of more number of seed sources for iodine value, cetane number and saponification value. Hence...

Biosorption of heavy metals by immobilized and dead fungal cells: A comparative assessment

Heavy metal resistant fungi were isolated from an electroplating industrial effluent samples that uses copper, cadmium and lead for plating. These isolates were tested to evaluate their applicability for heavy metal removal from industrial wastewaters. Initially the physico-chemical parameters of the samples were analyzed. The optimum conditions of pH, biomass concentration and heavy metal concentration were determined...

Determination of trace metal levels in water and sediments of River Benue in Adamawa state, Nigeria

This work was carried out in order to determine the trace metal levels in River Benue to acertain the extent of pollution of the water body. Trace metal levels in water and sediments of River Benue were determined using the atomic absorption spectroscopy (AAS) model. The results suggest that trace metal concentrations in River Benue were generally greater in the sediment samples than water samples. Among the metals...

Adjustment of Brunt's equation parameters for the Northern Brazilian Pantanal

Researches involving the long-wave balance have intensified in order to understand the environmental performance of micrometeorological variables. This study tried to determine the parameters of Brunt’s equation for the northern Pantanal of Mato Grosso, using “genetic algorithm”. The results show that the values estimated by the model significantly approached the values obtained with data collected...
