The process of mining affects all the components of environment and ecology. resulting in different types of pollution problems like soil, surface and ground water pollution. Acid Mine Drainage (AMD) and mine spoil dumps may contain an elevated amount of Heavy metals. Physiological effect of heavy metal toxicity on algal species like Chlorella vulgaris, Scenedesmusbijugatus, Oscillatoriaamphibi...

Prunella vulgaris L., commonly known as "self-heal" or "heal-all," is a perennial herb with a long history of medicinal use. Phenylalanine ammonia-lyase (PAL), cinnamate 4-hydroxylase (C4H), and 4-coumarate:coenzyme-A (CoA) ligase (4CL) are important enzymes in the phenylpropanoid pathway and in the accumulation of rosmarinic acid (RA), which is a major secondary metabolite in P. vulgaris. In t...

The variation of paralarval abundance in a region subjected to wind-driven upwelling (Ria of Vigo, northwestern Spain) was studied. Research cruises were undertaken during the favourable upwelling season (May to October) in 2000 and 2001. Each cruise included biological and hydrographic sampling and consisted of five stations in waters located to the east and west of the Cies Islands. A total o...

We have confirmed here that the seeds of the common bean (Phaseolus vulgaris, L.) do not support development of the bruchid Callosobruchus maculatus (F.), a pest of cowpea [Vigna unguiculata (L.) Walp] seeds. Analysis of the testa (seed coat) of the bean suggested that neither thickness nor the levels of compounds such as tannic acid, tannins, or HCN are important for the resistance. On the oth...

Regeneration after experimental disturbances (burning, cutting and ploughing) was studied in a heathland dominated by Calluna vulgaris (L.) Hull located in NW Spain. Regeneration of C. vulgaris was better after burning and ploughing than after cutting. When cut, this species was replaced by another resprouting ericaceous species, Erica tetralix L. Calluna seedlings suffered high mortality in th...

As part of an ongoing research project on the pollination networks in European heathlands, the objective of this study was to assess the insect visitor guild on Calluna vulgaris (L.) Hull (Ericaceae). We focused the study on a region renowned for its largely well-preserved heathlands, the Cévennes National Park, Southern France. In 2013, flower visitors were observed over 3 d per site, in four ...
