THE SNOW GEESE OF LA PÉROUSE BAY. NATURAL SELECTION IN THE WILD
Cooke F., Lank D. B., Rockwell R. F.
Este título evalúa los resultados de uno de los estudios a largo plazo más importantes de aves a fines del siglo XX. Los autores evalúan el funcionamiento de la selección natural sobre el color del plumaje del Ánsar nival (Anser caerulescens), el momento estacional de la reproducción, el tamaño de la nidada, el tamaño del huevo y el tamaño del cuerpo. Con información recopilada durante 26 años sobre 40,000 gansos adultos marcados individualmente, 45,000 nidos y más de 110,000 polluelos en una colonia en el norte de Manitoba, este trabajo es un hito en biología aviar y genética de poblaciones.
