Specimen collection: An essential tool
COLLECTING BIOLOGICAL specimens for scientific studies came under scrutiny when B. A. Minteer et al. [“Avoiding (re)extinction,” Perspectives, 18 April, p. 260] suggested that this practice plays a significant role in species extinctions.
Based on a small number of exam- ples (rare birds, frogs, and a few plants), the authors concluded that collection of voucher specimens is potentially harmful to many species, and that alternatives— photographs, audio recordings and nonlethal tissue sampling for DNA analysis—are sufficient to document biological diversity.
