Argentine Ant- Facts

Image
Environmental DNA (eDNA) of Argentine Ant was successfully detected by researchers. It was detected in surface soil samples collected from Kobe Port Island and Kyoto’s Fushimi District.   Ø   What are the concerns? ü   Both the areas have faced huge destruction caused by this invasive species called Argentine Ant. ü   Invasive ant species causing severe damage across the world. So, its early detection and rapid elimination is essential to control their populations. ü   However, current pest control methods in inefficient. Methods includes direct detection techniques like visual observation, classification, capture, elimination, observation and evaluation which requires special knowledge, labour and time.   Ø   What researchers suggests? ü   Researchers suggests, issue of Argentine ant cannot be eradicated by focusing on one species. They found, eDNA analysis effective in providing a useful tool to observe and evaluate invasion, estab...

Difference between Exponential Growth and Logistic Growth

 Difference between Exponential Growth and Logistic Growth Exponential Growth vs. Logistic Growth The difference between exponential growth and logistic growth can be seen in terms of the growth of the population. Population growth is defined as an increase in the size of a population over a specific time period. The growth rate is calculated using two factors – the number of people and the unit of time. This rate is influenced by the rate at which birth takes place every year (also known as the birth rate). It is also influenced by the rate at which living beings die (also known as the death rate). The size of the population does not rise indefinitely because of the limitation of certain factors. These factors are water and nutrients, space and light as well as the existence of competitors. The explanation for population growth can be done using 2 growth models – exponential growth and logistic growth. Exponential growth and logistic growth are terms th...
