why are bats going extinct?

In the UK, bat populations have declined considerably over the last century.
What is dilution to extinction method? This method involves physical isolation of target microbes from mixed populations, culture media simulating natural habitats, and removal of toxic compounds. In this protocol, we describe detailed procedures for isolating freshwater oligotrophic microbes, as well as the essence of the dilution-to-extinction culturing.
How do you make a bacterial consortium? To prepare the microbial consortium, loopfuls of each isolated species stored on nutrient agar slant were inoculated together in 50 mL MSM containing 200 mg/L solid Phe in a conical flask. The flask was shaken in an orbital shaker (120 rpm) at 37 ºC in the dark for 4 days to reach the phase of exponential growth.
What is lost when there is a lack of diversity? What then will happen if the current decimation of organic diversity continues?
