What the literature leaves open

  • There is a need for more research on the effects of forest fires and insect outbreaks on wood quality, - There is a lack of understanding of the challenges of processing disturbance-affected wood and its potential uses

    Processing and End-Uses of Wood Affected by Forest Fires, Eastern Spruce Budworm and Mountain Pine Beetle Outbreaks · 2026 · DOI

  • Foliar diseases are a major health constraint on the sustainability of eucalypt forestry. The study faced challenges in identifying replacement trees from 2013 and obtaining tree-level pathogen confirmation. The study had to contend with limited metadata on crown position, height within the crown, exposure, and shoot type.

  • The study suggests that future research should investigate the economic value of deadwood ecosystem services in different forest ecosystems. The study recommends that future research should explore the use of other valuation methods, such as choice experiments. The study suggests that future research should examine the impact of deadwood management on biodiversity and ecosystem services.

    How Are Deadwood Ecosystem Services Valued?: · 2026 · DOI

  • The study identifies a research gap in the understanding of the economic value of deadwood ecosystem services. The study notes that prior research has focused on the ecological importance of deadwood, but not its economic value.

    How Are Deadwood Ecosystem Services Valued?: · 2026 · DOI

  • The ecological damage caused by acid-induced pollutants is not well understood. The impact of sulfur dioxide and nitrogen oxides on forest growth is not well understood.

    Acid Precipitation: What is it Doing to our forests? · 1983 · DOI

  • The project may be limited by the fact that some audiences may still remember the theatrical surface more strongly than the deadwood function or the threshold logic behind it. The project may be limited by the fact that link decay, script failure, platform migration, and font and image compression can lead to reduced readability.

    Deadwood as Stage, Beetles as Evidence: Translating Forest Degradation into a Web-Based Narrative in Crete · 2026 · DOI

  • Future research could explore the development of new web-based environmental media prototypes. Future research could explore the use of indicator species in environmental monitoring and conservation. Future research could explore the application of the project's findings to other environmental contexts.

  • The lack of understanding of the effects of Douglas-fir on soil properties in comparison to native tree species. The need to evaluate the potential of Douglas-fir as a site-improving species.

    Zlepšuje douglaska tisolistá půdní podmínky? Srovnání humusových forem se smrkem ztepilým v jižních Čechách · 2026 · DOI

  • The impact of Norway spruce forest dieback on understory species diversity is not sufficiently understood. There is a lack of research on spontaneous forest regeneration in nature reserves.

    Bylinné patro a zmlazení dřevin v sekundárních smrčinách ovlivněných kůrovcovou gradací ve vybraných zvláště chráněných územích Beskyd · 2026 · DOI

  • The study identifies a gap in the understanding of the diversity of stag beetles in China. The study aims to fill this gap by describing a new species of Dorcus.

    A new stag beetle of the genus Dorcus MacLeay, 1819 from Xizang, China (Coleoptera: Lucanidae: Lucaninae) · 2026 · DOI

  • Field evidence linking early foliar damage, spacing, and later plantation performance remains limited for Eucalyptus nitens under Atlantic conditions. There is a need for studies that examine the effects of spacing and seed-lot contrasts on foliar necrosis, survival, and growth in Eucalyptus nitens.

    Spacing effects and seed-lot contrasts in field-expressed foliar necrosis, survival, and growth of Eucalyptus nitens in a Nelder genetic trial under Atlantic sanitary conditions · 2026 · DOI

  • There is a lack of understanding of historical forest use practices and their ecological consequences. Few studies have examined the effects of historical forest use practices on carbon stocks. There is a need for more effective forest management strategies that take into account historical forest use practices.

    The Effect of Mid-Nineteenth-Century Forest Use Practices on Carbon Stocks of Mountain Forests in the Alps · 2026 · DOI

  • The mechanisms linking soil properties, isotopic signatures, and tree growth remain incompletely understood. Clearer interpretations of how soil properties influence tree performance are needed.

    Stable isotopes as integrators of soil biogeochemistry and tree growth across contrasting hardwood forest soils · 2026 · DOI

  • Knowledge of the overall syntaxonomic and habitat variability of forest communities with Arolla pine (Pinus cembra) within the Tatra Mountains (Western Carpathians) is still insufficient as field research was hindered by their hardly accessible localities and deforestation for high mountain grazing.

    CONTRIBUTION TO KNOWLEDGE ON THE VARIABILITY OF AROLLA PINE WOODLANDS OF THE NORTH-EASTERN TATRA MOUNTAINS · 2021 · DOI

  • Throughfall and stemflow are potentially important canopy-mediated nutrient pathways, particularly for potassium and base cations, but direct studies in tropical deciduous plantation canopies are scarce.

    Nutrient Recycling under Deciduous Plantations in the Tropics and Subtropics: Mechanisms, Dynamics and Management Implications · 2026 · DOI

  • C_LIO_LIMost previous studies describing the invertebrate communities of rot holes and the factors determining their structure focus on a narrow range of invertebrate taxa, and many host tree species remain unexplored.

    Local and biogeographical determinants of the diversity and structure of invertebrate communities in rot holes of ash, Fraxinus excelsior · 2026 · DOI

  • Future studies should focus on areas with limited research on litter carbon stocks in the Amazon. Future studies should aim to improve the methodological detail in the assessment of litter carbon stocks. Future studies should examine the impact of land-use and land-management practices on litter carbon stocks in the Amazon.

  • The remarkable achievements of the men of the Canadian Forestry Corps—who would number almost 32,000 by November 1918—are little known.

  • The effectiveness and trade-offs of retention forestry practices for biodiversity conservation remain unquantified in continuous-cover forests of Central Europe, and stakeholder support and integration pathways into management are unclear.

    Evaluating the effectiveness of retention forestry to enhance biodiversity in production forests of Central Europe using an interdisciplinary, multi‐scale approach · 2020 · DOI

  • While the use of retention in these forests is plausible, the evidence base for its application is lacking, trade-offs have not been quantified, it is not clear what support it receives from forest owners and other stakeholders and how it is best integrated into forest management practices.

  • However, the intensive utilization causes the formation of the secondary communities, so that further studies of the vegetation diversity should be carried out with taking into consideration stand age and homogeneity of site conditions.
