摘要

许多栖息在木材上的真菌物种，特别是在北欧国家的北方森林中，面临着严重的灭绝风险。商业林业的历史影响导致了原始森林的破碎，这意味着从这些地区消失的物种可能不会自然地回到新的受保护的栖息地。本研究探讨了接种作为一种管理工具的潜力，以帮助重新引入受威胁的真菌物种。具体而言，我们测试了与死松木相关的红色真菌物种能否在接种的松木上成功建立，并确定了影响接种成功的因素。我们在选定的森林中培养5种目标菌种（Anthoporia albobrunnea, Antrodia crassa, Antrodia infirma, Crustoderma corneum, dihomitus squalens）的菌丝体和接种的松树原木，监测原木特征，并对接种前后的真菌群落进行DNA分析。我们的研究结果表明，所有物种都成功地在至少一些接种的原木上建立（28-60%的成功率），原木特征对真菌丰度的影响是可变的。此外，某些真菌的存在与接种物种的成功相关。这些结果表明，接种是一种很有希望的方法，可以帮助在适当的森林生境中恢复受威胁的木材真菌。评估结果的成功和种群的可持续性需要长期监测，而进一步探索替代技术可以提高森林管理实践中重新引进工作的有效性。

Reintroducing threatened pine-associated fungal species in boreal forests

Many species of wood-inhabiting fungi, particularly in the boreal forests of Nordic countries, face significant extinction risks. The historical impact of commercial forestry has led to fragmented old-growth forests, meaning that species lost from these areas may not naturally return to newly protected habitats. This study investigates the potential of inoculation as a management tool to aid the reintroduction of threatened fungal species. Specifically, we tested whether red-listed fungal species associated with dead pine wood could successfully establish in inoculated pine logs and identified factors influencing inoculation success. We cultured mycelium from five target species (Anthoporia albobrunnea, Antrodia crassa, Antrodia infirma, Crustoderma corneum, Dichomitus squalens) and inoculated pine logs in selected forests, monitoring log characteristics and conducting DNA analysis of the fungal community before and after inoculation. Our findings demonstrate that all species successfully established in at least some of the inoculated logs (28–60% success), with variable effects of log characteristics on fungal abundance. Additionally, the presence of certain fungi correlated with the success of the inoculated species. These results suggest that inoculation can be a promising method for aiding the recovery of threatened wood-inhabiting fungi in appropriate forest habitats. Long-term monitoring is necessary to assess fruiting success and population sustainability, while further exploration of alternative techniques could enhance the effectiveness of reintroduction efforts in forest management practices.

期刊介绍： Environmental Management offers research and opinions on use and conservation of natural resources, protection of habitats and control of hazards, spanning the field of environmental management without regard to traditional disciplinary boundaries. The journal aims to improve communication, making ideas and results from any field available to practitioners from other backgrounds. Contributions are drawn from biology, botany, chemistry, climatology, ecology, ecological economics, environmental engineering, fisheries, environmental law, forest sciences, geosciences, information science, public affairs, public health, toxicology, zoology and more. As the principal user of nature, humanity is responsible for ensuring that its environmental impacts are benign rather than catastrophic. Environmental Management presents the work of academic researchers and professionals outside universities, including those in business, government, research establishments, and public interest groups, presenting a wide spectrum of viewpoints and approaches.
