Heterogeneous agroforestry systems play an important role in maintaining animal pollinator diversity (Klein et al. 2003, Perfecto et al. 1996), most likely by extending floral resources in lean periods. An understanding of the mutualistic relationship between flower-visiting insects and crop species in such agroforestry systems (Kearns et al. 1998), particularly on the diversity of pollinator species, their spatio-temporal variations, foraging behaviour (Cunningham 2000, Greenleaf & Kremen 2006, Klein et al. 2003) and their pollination efficiency (Motten et al. 1981), is important as they are some of the crucial biological predictors of pollination success.

Seasonal changes in the climate, as well as in plants and species living in this environment, which causes serious problems. Current work was carried out to evaluate the seasonal impact on the  concentration of iron (Fe) and zinc (Zn) in soil, forages and animals. A semi arid dry climatic area of Pakistan was selected to find out the seasonal effects on soil and availability of Zn and Fe, and its translocation to forages and animals. Twenty seven forages were collected and 320 ruminant samples collected from two sites in four seasons. Effect of spatial-temporal variations were studied on the ruminants of four physiological stages (Does, Bucks, Wether and Juvenile). Different sources from goats including blood, feces and urine were collected for the analysis of Zn and Fe. Results showed that both elements  in soil were significantly (P < 0.05) affected by season and site x season. In forages, only site showed significant effect on Fe and Zn, while Zn was affected non-significantly (P > 0.05) by season and site x season. Zn and Fe in goats were non-significantly affected by season and source x stages, while significantly affected by sites and sources. All values of both elements were in safe limits except deficiency of Fe (1.69 to 2.33 mg/L) in blood. Results of health indices were also in the limits. Current work encircles the spatio- temporal effects on mineral availability in the food chain and also concern the health effects related to ruminant health.
