<abstract xmlns="http://www.w3.org/1999/xhtml"> Regeneration patches have key role in forest stand dynamic, new findings about the structural properties of patches can be useful in forest ecosystem management. We quantified the spatial and structural pattern of regeneration patches in old growth beech stands in a Gorazbon forest in the northern Iran. 461 patches were measured that covered 8.3% of total forest area. Patch size varied from 55 m2 to 2987 m2. The majority of the patches were small; 71.6% were less than the mean patch area of 1330 m2 and were belonged to sapling patches (N = 295), also 166 seedling patches were recorded. The results showed that the major distribution pattern of patches in different compartments was random and patchy. These results confirm this fact that human activity and natural disturbances should be providing a homogenous spatial distribution pattern of patches in the high spatial scale. However among different forest stand and compartments spatial pattern of patches change randomly, that can create the natural situation and near to nature structure in beech stands</abstract>

Spatial distribution of regeneration patches in old growth oriental beech forests in northern Iran

<abstract xmlns="http://www.w3.org/1999/xhtml">Cold-hardiness can be measured by supercooling points – the temperature
at which spontaneous freezing occurs. Seasonal changes in supercooling point were
assessed in field-collected predacious carabid beetle species: Carabus granulatus L.,
Pterostichus oblongopunctatus L. and Platynus assimilis Payk. (Coleoptera: Carabidae).
Supercooling ability of these beetles changed seasonally. The tested carabid beetles
proved to belong to freeze-avoiding cryotype.</abstract>

Forestry Studies

 Forestry Studies | Metsanduslikud Uurimused is a peer-reviewed journal managed by the Institute of Forestry and Rural Engineering, Estonian University of Life Sciences. The journal publishes original research articles, reviews, technical reports and short communications. Papers are published in English or Estonian with English summary. Authors whose mother tongue is not English are strongly urged to have their manuscripts reviewed linguistically before submission. Submission of an article is understood to imply that the article is original and is not being considered for publication elsewhere. Manuscripts generally should not exceed 25 one-sided 1.5-spaced printed pages, including tables, illustrations, references and abstract. Reviews must not exceed 20 pages, technical reports 5 pages. The authors should aim to submit their work as concisely as possible and longer papers will be accepted under exceptional circumstances. Suitable manuscripts are considered by at least two independent referees before acceptance.   Why subscribe and read   the journal publishes research papers on all aspects of forestry (silviculture, dendrology, tree physiology and genetics, forest products, forest operation and techniques, forest economics and policy, etc.), and also close subjects (environmental protection, ecology, botany, zoology, entomology, pathology, soil science, etc.),  the journal is published twice a year in paper and electronic versions,  peer reviewed journal by experts from Europe and US,  publishing history since 1939.   Why submit   submissions accepted in a wide range of categories: original research articles, reviews, technical reports and short communications,  rapid review (by two independent referees) and fast editing process,  coverage by major abstracting and indexing services,  publishing without charge,  accessibility through MetaPress platform.   Archiving  Sciendo archives the contents of this journal in Portico - digital long-term preservation service of scholarly books, journals and collections.  Plagiarism Policy  The editorial board is participating in a growing community of Similarity Check System's users in order to ensure that the content published is original and trustworthy. Similarity Check is a medium that allows for comprehensive manuscripts screening, aimed to eliminate plagiarism and provide a high standard and quality peer-review process.
