A mesocosm is a controlled environment which can be used to study impacts on an ecosystem under realistic conditions. They can be applied to aquatic environments to look at the impact of substances or other disturbances such as chemicals, temperature and nutrients on the ecosystem. Brine shrimps are crustaceans, relatives of fairy shrimps and water fleas. They are also related to lobsters, shrimp and crabs.

Have you ever wondered why pandas are going extinct?

1. Introduction Forensic entomology has profound utility in contemporary time. Insects and their arthropod counterparts are used in the legal investigations to aid the forensic analysis of decomposing materials (Mumcouglu et al., 2004). It is used by criminal investigators to try to solve homicide cases by attempting to reconstruct the crime scene and establish the cause of death. In addition to human death investigations, it can be used to determine the death of animals and other wildlife crimes
Introduction Sorghum bicolor (L.), often referred to as grain sorghum, is a grain of global importance (Anderson et al. 1949), because it is a rich source for food, feed, and fuel (Wang et al. 2008). Sorghum ranks fifth in the world for produced cereal crops. In areas that are frost-free, grain sorghum is a very important and economical crop. Sorghum was introduced in North America from the tropical regions of Africa in 1853. It is a very hardy crop that can grow in very tough environments. Sorghum
Purple Loosestrife The scene is breathtakingly beautiful, a thick brush of purple flowers blankets Canada's wetlands.

This unnatural silence is disturbing, the favourite flowers that used to litter this landscape are no longer visible, the water that used to ripple continuously is perfectly still. The wetland is dead, except for this overpowering, hardy purple
