| Abstract | To examine the effects of frequent fires on species composition of the boreal forest in northern Mongolia, we investigated regeneration patterns, including reproductive pathways, post-fire seed sources, and site preferences, of four common tree species (Betula platyphylla, Larix sibirica, Picea obovata, and Pinus sibirica). Regeneration patterns differed among B. platyphylla, L. sibirica, and the two evergreen conifers. B. platyphylla regenerated vigorously only after fire irrespective of the presence/absence of nearby seed sources, whereas post-fire regeneration of L. sibirica was more dependent on the presence of nearby seed sources. These two species did not regenerate in mature stands where mature trees of these species were growing. In contrast, no post-fire recruitment of P. obovata and P. sibirica was observed, whereas continuous recruitment of these species was observed in mature stands. The frequent fires that accompany illegal logging may result in larger burned areas and increase the risk of local extinctions of seed sources. The enlargement of burned areas is likely to favor post-fire recruitment of B. platyphylla. Seed dispersal limitation seems to have less effect on B. platyphylla than on the other species because of the wider seed dispersal range and vegetative reproduction capability of this species. Consequently, fires in the northern Mongolian boreal forest likely promote the relative dominance of B. platyphylla and threaten the existence of the evergreen conifers. |

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.
