TY - GEN A1 - Andrzejewski, R. A1 - Liro, A. N1 - The crowns of the teeth were found to wear more slowly in a population of field mice, Apodemus agrarius (Pallas, 1771) living to a great extent on additional food (oat grains) than could have been expected from their absolute age. Age estimated on the basis of eye lens weight was accordance with the absolute age of individuals. The authors suggest that slower teeth wear was due to replacement of hard animal feed (chitin) by oats L1 - http://rcin.org.pl/Content/16278/PDF/BI002_2613_Cz-40-2_Acta-T22-nr29-393-395_o.pdf M3 - Text VL - 22 CY - Białowieża PY - 1977 IS - 29 EP - 395 KW - ścieranie zębów KW - Mysz polna KW - Apodemus agrarius SP - 393 T1 - Effect of different kinds of feed on wear of the teeth in individuals of a field mouse population UR - http://rcin.org.pl/dlibra/publication/edition/16278 ER -
