| Moreover, golden eagles have a Holarctic distribution and are not threatened with extinction in North America. |
|
| Moreover, most Holarctic migratory ducks that pair seasonally do so during winter away from the breeding grounds. |
|
| These represent robust wolf-sized dogs thought to have derived from the large northern Holarctic wolf form C. l. lupus. |
|
| In this study, we were interested in updating available information on an uncommon migratory seabird with a Holarctic distribution, the ivory gull. |
|
| The significance of latitudinal variation in body size in a Holarctic ant, Leptothorax acervorum. |
|
| Two of the three remaining Holarctic species are social parasites, inquilines, which have different hosts in the Nearctic and Palearctic Regions. |
|
| On grasses, the most abundant was Halorates oxypaederotipus, whereas Misumena vatia, a Holarctic species, was, found preying on flowers. |
|
| Once widespread across the Holarctic, it has disappeared from many areas which are now more heavily populated by humans. |
|
| Our findings indicate a potential Holarctic distribution of these two species. |
|
| According to this view, the family Arionidae is widely distributed in the Holarctic region. |
|
| Flood disturbance regimes influence rainbow trout invasion success among five holarctic regions. |
|
| The distribution of this species should also be explored as its occurrence suggests a wide holarctic range. |
|
| By about 15,000 years ago, Equus ferus was a widespread holarctic species. |
