| Abstract | In the sparse larch forests of the upper Kolyma River, hypopi of the mite Anoetus myrmicarum (Scheucher, 1957) were found in several nests of the ant Formica lemani Bondroit, 1917. These mites were not found in hundreds of nests of the other 10 ant species examined in northeastern Asia. A possible ecological and physiological conditionality of the restricted distribution of phoretic mites was analyzed. For this purpose, coldhardiness of mites and their ant hosts, the biotopic distribution and the structure of nests, and the temperature conditions of overwintering were examined. At the stage of hypopus, the mites overwintered on ants in the overcooled stage; their mean supercooling temperatures (SCP) varied from −25.8 ± 0.3°C to −27.7 ± 0.4°C (min −32.2°C, n = 157). These values were by 0.1 to 7.0°C lower than the mean SCP of the ants from 8 tested nests of F. lemani (−20.7 ± 0.5°C to −25.7 ± 0.8°C). The soil temperatures at the level of winter chambers varied from −12°C to −15°C. Scarcity of findings of Anoetus myrmicarum in the Kolyma Highland is not associated with the limited cold-hardiness of the examined stages, but is most probably determined by interrelations between mites and ants. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
