Juniper Publishers- Open Access Journal of Environmental Sciences & Natural Resources Role of Micro Nutrients Bio- Fortification in Agriculture: A Review Authored by Muhammad Adnan Abstract Calcium, Zinc and iron are in the list of essential plant nutrients for growth and development. Bio fortification or foliar fertilization is very important strategy for crop management, which is very useful for obtaining maximum crop yield and quality. Bio fortification is used as a way of providing additional doses of macro- and micro-nutrients, stimulants, plant hormones and other favorable elements. The present review describes the role of calcium, zinc and iron in agricultural crop production and impact of bio-fortification of nutrients on crops. Keywords:   Calcium; Zinc; Iron; Bio fortification Go to Introduction WHO reports describes that lack of micronutrients are major threat to world population [1]. Bio fortification word is a greek work “bios” means “life...

Juniper Publishers- Open Access Journal of Environmental Sciences & Natural Resources Mesopredator Release Theory: Comparing Mesocarnivore Abundance and Prey Choices in an Urban Landscape and Impacts on Prey Populations Authored by Melissa L Karlin Abstract According to the mesocarnivore release theory, when apex carnivores from the landscape the populations of mid- to small-sized carnivores explode and many prey species decline. Apex predators are replaced by smaller mesocarnivores, such as domestic cats  (Feliscatus),  which should consume smaller prey such as birds, arthropods, and rodents, while larger mesocarnivores, such as Coyotes  (Canislatrans),  should prey on small mammals such as rodents and rabbits. The purpose of this research was to determine the abundance of mesocarnivores in two urban landscapes, and by determining their prey choices, estimate their impacts on small mammal and bird population abundance in their landscape. Birds ...
