The maritime pine (Pinus pinaster) is the main conifer species in Portugal, occurring mainly central and northern regions of country. In addition to its environmental significance, it plays an important socio-economic role, supported by a robust forest sector. face climate change driven release CO2 into atmosphere, forests play essential role mitigating these changes storing large amounts carbon their biomass. This study assesses impact management, focusing on thinning, accumulation naturally regenerating municipality Boticas, Portugal compares scenarios with without intervention. To simulate growth scenarios, Modispinaster software used, through mathematical models adjusted for input initial field data, generates evolution regarding biomass accumulation. Additionally, allows visualization forest’s dendrometric characteristics throughout cycle, enabling creation balance analysis across multiple scenarios. results demonstrate that management based thinning increases retention, reducing early mortality promoting larger diameter trees. Although natural initially accumulate more carbon, reduction competition managed greater from 24th year onwards, reaching 178 tons at end contrast 143 unmanaged areas. result (natural) was negative (−18 tons), while forest, positive (54 tons). supports thesis although intense less frequent than events, effective absence interventions. Thinned optimize Pinus pinaster, improving long-term retention mortality. Managed show balance, highlighting importance sustainable strengthening ecological resilience.

Forest clear‐cuts support diverse moth fauna but lack common grassland species

Abstract Forests ecosystems sustaining most of the terrestrial biodiversity are under increasing anthropogenic pressure. Both protection remaining natural forests and mitigation negative effects silviculture primary conservation concern. Clear‐cut areas main open habitats in production forests, potentially offering temporary refuge for species from declining semi‐natural grasslands. Although several groups flower‐visiting insects, including butterflies, have been reported to thrive clear‐cuts, a taxonomically comprehensive understanding insect fauna utilizing these is lacking. In this study, we examined assemblages nocturnal macromoths (Lepidoptera: Marcoheterocera) forest clear‐cuts varying age (2–6 years) regeneration regimes (natural vs. artificial) northern Europe. Using automatic sugar‐bait traps, sampled 50 three pairs forest‐grassland reference sites over two summers. Nocturnal moths were highly diverse, harbouring 50% regional pool noctuids. However, common grassland‐associated species, as well few nearly absent. similarity between clear‐cut increased with age, recorded characteristics had little overall influence on moth assemblages. Artificially regenerated characterized by more vegetation structure, supported slightly higher richness diversity compared naturally regenerating sites. Policy implications . Our results highlight role supporting biodiversity. As such, warrant special consideration distinct habitat type. maintenance methods appear weaker than various other groups. More importantly, absence grassland highlights that cannot fully replace traditional habitats. This underscores importance conserving

Molecular Characterisation of Post-Fire Naturally Regenerated Populations of Maritime Pine (Pinus pinaster Ait.) in the North of Portugal

Fire, Год журнала: 2024, Номер 7(3), С. 88 - 88

Wildfires act as a selection force threatening the sustainability and diversity of forest genetic resources. Few studies have investigated effects wildfires. Species with perennial canopy seed banks in serotinous cones soil or long-distance pollen dispersion can preserve population differentiation under normal fire regimes. To test this hypothesis, we characterised molecularly Pinus pinaster Aiton (maritime pine) seedlings produced from seeds sampled post-fire, naturally regenerated populations that had been subject to different regimes North Portugal using inter-simple sequence repeats (ISSRs). The burned once (A), twice (B), three (D) times no prior history (C, control). Given globally low germination ability, only 104 plantlets were described. These grouped according their origin population. Intra-group ISSR polymorphism ranged 72.73% (B) 89.41% (D), revealing among groups originating experienced recurrence. Overall, unaffected allowed us accept hypothesis. Our findings enhance our understanding species ability withstand fire-induced challenges responses wildfires, guiding conservation endeavours management strategies bolster ecosystem resilience.

Neighborhood Competition and Understory-Associated Vegetation Are Important Factors Influencing the Natural Regeneration of Subtropical Mountain Forests

Forests, Год журнала: 2024, Номер 15(6), С. 1017 - 1017

Natural regeneration is deemed essential for maintaining biodiversity and ecosystem stability. Previous studies, however, have primarily concentrated on regions exhibiting limited environmental climatic variability, overlooking the classification of natural based age source. Research conducted at mesoscale, characterized by increased variability incorporation neighborhood competition understory-associated vegetation, enhances our comprehension multifaceted influences regeneration. To comprehend this issue, study implemented 60 plots, each measuring 20 m × m, across five distinct areas Chongqing, China. Twenty explanatory variables were chosen from diverse categories: understory competition, stand structure, factors, factors. And naturally regenerated species classified into seedlings saplings, as well endogenous exogenous species, their origin. We examined response different categories to various factors constructed a structural equation model (SEM) significant investigate direct indirect effects A total 61 tree belonging 29 families 42 genera found in area, regenerating with high importance values Quercus fabri, Robinia pseudoacacia, Alangium chinense, Cunninghamia lanceolata, Ligustrum lucidum. It was that vegetation explained largest proportion (more than 50%) variation regeneration, forests clumped distribution (W), mingling index (M) strong (H) had reduced capacity.

Tree ontogeny is the genetic trajectories of regenerative processes in trees, repeating time and space, including both development reproduction. Understanding principles tree a key priority emulating natural ecological patterns that fall within calls for closer-to-nature forest management. By recognizing respecting growth individual trees stands, managers can implement strategies align with inherent dynamics ecosystem.

Accurate predictions of community stability feedback to climate warming depend on an advanced understanding responses the key species. The transition from seed germination seedling establishment is most vulnerable stage plants, which determines maintenance plant diversity and resistance change. To elucidate how physiological characteristics Machilus gamblei seedlings will respond future global warming, artificial experiments (infrared +0.75 ℃, +1.5 +3 +4 ℃) were conducted at Ailao Mountain National Nature Reserve in Yunnan Province, China. their adaptation different conditions studied, contents nutrients, chlorophyll, nonstructural carbohydrate (NSC) leaves measured. results showed that: (1) increasing temperature by 0.75 ℃ did not affect survival rate or seedlings, but 4 reduced seedlings; (2) As increased 1.5 3 chlorophyll production improved, thus particularly promoting accumulation NSC starch content. In summary, our work suggests that increase might be conducive growth two-year experimental period, would threaten development.
