Key words: Seeds, cuttings, layering, plant growth, roots, Pseudospondias microcarpa A. Rich.

Abstract

Pseudospondias microcarpa A. Rich is a tropical tree species, which is not domesticated despite its food and pharmacological potentials. This study aims at introducing its domestication using two types of substrate. The first substrate (S1) is a mixture of compost and local soil while the second substrate (S2) is only made of local soil. Continue reading

Predation potential of foliage spiders and estimates of utilization curve, niche breadth and overlap in cotton filed from Punjab, Pakistan – JBES

Key words: Spiders, Feeding niche, Utilization curve, Niche breadth, Niche overlap, Specific overlap.

Abstract

Production of cotton is restricted by pest infestation causing deterioration in lint quality. Spiders being generalist predators regulate insect populations. Bio diversity and relative abundance of spiders as predator as well as feeding niches of nine coexisting spider species in cotton were computed and compared for the niche breadth; niche and specific overlaps.
