The potential of White Stork (Ciconia ciconia) nest lining to evaluate the functional diversity of Coleopteran fauna Open
Collecting arthropod samples is usually very invasive because these organisms die during sampling, and it is hard to obtain a statistically robust sample. The availability of arthropods is critical for the survival of the youngest White St…
