| some aspects of thermoregulation in newborn reindeer calves (rangifer tarandus tarandus). | at birth reindeer calves often are exposed to sub-zero ambient temperatures (ta) sometimes even combined with wind and precipitation. the resting metabolism was measured in three different age groups (1, 7 and 14 days old) at ta's of -20, -5, 10 and 20 degrees c. resting metabolism in the thermoneutral zone decreased from 5.1 w x kg-1 at day 1 and 7 to 4.8 w x kg-1 at day 14. at day 1 apparent lower critical temperature (tlc) was 11 degrees c, while at day 7 it was 7.7 degrees c and at day 14 7. ... | 1985 | 2858960 |
| serological survey of herpesvirus infections in wild ruminants of france and belgium. | the presence of antibodies against bovine herpesvirus 1 (bhv-1), bovid herpesvirus 6 (bhv-6), herpesvirus of cervidae type 1 (hvc-1), reindeer herpesvirus, bovine herpesvirus 2 (bhv-2) and bovid herpesvirus 4 (bhv-4) was investigated in wild ruminants of france and belgium between 1981 and 1986. there were no animals serologically positive for bhv-4. antibodies against bhv-2 were demonstrated in roe deer (cervus capreolus) (less than 1%) and chamois (rupicapra rupicapra) (1%) in france. animals ... | 1988 | 2836635 |
| vascular control of brain cooling in reindeer. | the cold venous effluent returning from the nose of the heat-stressed reindeer may be distributed through angular oculi veins for selective cooling of the brain and through facial veins for general body cooling. in vitro experiments indicate that adrenergic receptors of the angular oculi vein are exclusively of the alpha-adrenergic type, whereas facial veins contain mainly beta-adrenergic receptors. we suggest that the antagonistic adrenergic neuroeffector organization of these veins plays a maj ... | 1988 | 2834969 |
| reindeer papillomavirus transforming properties correlate with a highly conserved e5 region. | a papillomavirus was isolated from the epithelial layer of a cutaneous fibropapilloma on a swedish reindeer (rangifer tarandus). reindeer papillomavirus (rpv) is morphologically indistinguishable from other papillomaviruses, but the restriction enzyme cleavage pattern of its genome is different. no sequence homology was detected between rpv dna and the dnas of bovine papillomavirus type 1 (bpv-1) and avian papillomavirus when hybridization was performed under stringent conditions. however, the r ... | 1987 | 2822949 |
| radiocesium uptake in reindeer on natural pasture. | in an experiment initiated after the chernobyl accident, a herd of reindeer was followed before and after a temporary move from a highly contaminated area (greater than 20 kbq 137 cs/m2) to a less contaminated area (less than 3 kbq 137cs/m2) of natural pasture. the animals grazed in a highly contaminated area until they were moved to the low contaminated area where they grazed from late november to late april. the level of 137cs in meat was about 12 kbq/kg at the time when the animals were moved ... | 1989 | 2814448 |
| cs-137 concentration in reindeer and its fodder plants. | radionuclides, especially the long-lived 137cs (physical half-life 30 years), are accumulated efficiently in the northern, subarctic, lichen-reindeer-man foodchain. until the chernobyl accident the fallout nuclides studied originated from nuclear weapons tests. after this accident some fresh fallout was deposited in finnish lapland. lichens grow very slowly and collect nutrients very efficiently from air, rain and snow. during winter the basic fodder plants for reindeer are lichens and some wint ... | 1989 | 2814447 |
| [isolation of viruses of antigenic complexes of california encephalitis and bunyamwera (bunyaviridae, bunuavirus) from mosquitoes in northeast asia]. | studies in suckling mice and by direct solid-phase enzyme immunoassay were carried out with 111,1 thousand aedes mosquitoes collected in july, 1986, in tundra, forest-tundra, and northern taiga of kamchatka region and chukotka autonomous district of magadan region (north-pacific natural area within 69 degrees-53 degrees north and 156 degrees-177 degrees east). eleven strains were isolated of which 7 were classified as members of the california encephalitis complex (tahyna-like strains) and 4 as ... | 1989 | 2800529 |
