Master of Biology FMIPA Jember University and Master of Biology FMIPA Brawijaya University held a collaboration to teach biodiversity courses online (15/9). Prof. Dr. Amin Setyo Leksono from Brawijaya University, as the speaker, delivered material on animal population estimation methods. “We need an animal population approach first, both census and sampling,” he initially said. Continuing the census requires a lot of personnel to count all the flora in an area. Meanwhile, sampling can be done using direct or indirect analysis.

Prof. Amin continued direct sampling itself, divided into several methods. “There are quadratic methods, transect lines, exploration and exclusion methods, and finally we have to calculate the population size,” he continued. For indirect methods, there are several methods, including traps, concentration calculations, trace counts, and interview methods. The conclusion from the initial session was that the benefit of animal estimation is knowing population dynamics patterns, including influencing factors. “We come to know the potential of each type, its role and benefits, and finally, what policies to take for this population,” he concluded.
