MARC recordLatitudinal variation in litter size of polar bears: ecology or methodology? / Andrew E. Derocher.
| Title: | Latitudinal variation in litter size of polar bears: ecology or methodology? / Andrew E. Derocher. |
| Author(s): | Derocher, Andrew E. |
| Date: | 1999. |
| In: | Polar Biology. (1999.), Vol. 22(5) (1999) |

Also examines influence of timing of sampling and sampling area (at dens or away from dens) on previously reported cline in litter size. |
| Notes: | Polar Biology. Vol. 22(5) :350-356 (1999). |
