فقہ اسلامی اور مغربی قانون کی روشنی میں حقوق دانش کے قوانین کاتحقیقی مطالعہ

Islam always emphasizes to use legal ways and means of earning. In contrary the legal and illegal sources of income have been explained in detail. The “Right of invention” is one of the most discussed issues among the Islamic Jurists. This right is related to the intellectual skills and capabilities of people. However, internationally intellectual property is a known concept that associates with right of publication, right of trademark, patent and right of goodwill et cetera. However, research must be conducted on inquiring rights of intellectual property in Islamic Sharia and comparison of these rights with those in Western laws. In this paper the historical review of the intellectual properly has been presented. Similarly, those various types and concerned ruling have been discussed in contrast with the Islamic and western law on descriptive research methods.

Diversity of Bombus Species Apidae: Hymenoptera and Utilization of Food Resources in Northern Pakistan

In agricultural habitat 10 bumblebee species were recorded. Of which 68.62% bumblebees were dominated by five species viz., B. asiaticus, B. melanurus, B. rufofasciatus, B. semenovianus and B. tunicatus. B. asiaticusatus, B. semenovianus, B. rufofasciatus, B. melanurus, B. avinoviellus, B. kashmirensis, B. subtypicus, B. haemorrhoidalis and B. himalayanus were encountered abundantly. However, in non- agricultural habitat 13 bumblebee species were recorded and more than 50% bumblebees were dominated by four species viz., B. asiaticus, B. avinoviellus, B. biroi and B. haemorrhoidalis. Significant variations were observed in the species richness of non- agricultural habitat but none in case of abundance at habitat level. However, same was true in case of non-cropped area as compared to cropped area in agricultural habitat which reflected the importance of non-cropped area as a refuge area for the development of bumblebee colonies which ultimately play a vital role in the pollination of crops, increasing their quality and quantity. Trifolium alexandrinum. Medicago sativa and Solanum tuberosum were the important only plant species which were visited by all bumblebee species in the cropped area. Cana indica, Centaurea cyanus, Cirsium sp., Dahlia x hybrid, Delphinium brunonianum, Geranium spp., Lonicera periclymenum, Prunella vulgaris, Ranunculus sp., Rosa spp., Rosa webbiana and Stachys spp were recorded in non cropped area. Similarly, the Impatiens spp. attracted significantly maximum bumblebees followed by Centaurea cyanus, Ranunculus sp., Artemisia dracunculus and Tamarix gaelic in non agricultural habitat. Forage species separated in to two conspicuous groups depending upon their utilization by bumblebees as a short and long- tongued bumblebees. Long- tongued bumblebees (B. haemorrhoidalis, B. asiaticus and B. melanuorus) were only attracted to Ranunculus sp., Raphanus raphanistrum, Centaurea cyanus, Prunella vulgaris, Cana indica, Stachys spp., Cirsium sp., Trifolium pretense, Delphinium brunonianum and Lonicera periclymenum. However, strong winds hindered the foraging activities of B. avinoviellus and B. biroi especially at Naltar.
