Landscape connectivity has a significant impact on ecosystem functioning and is related to the integrity, sustainability stability of ecosystems.Forest landscape widely acknowledged as key objective forest management, ecological conservation construction research. Even though Xinjiang low cover, high value. As result, using graph theory approach, this study assessed forests in Baluk Mountain Nature Reserve under different dispersal distances based theory. The study's findings demonstrated that mostly made up large number small patches patches. Although huge are crucial preserving general connection environment, also vital process should not be overlooked. Furthermore, calculation importance value (dIIC) found very contribution (dIIC> 30%) maintaining role connectivity. aforementioned results support notion requires giving priority protection patches, between ignored they could enhance overall This can determine which prioritized for conservation. beneficial only preservation regional biodiversity but enhancing ecosystem, helps safeguard fragmented ecosystems.

Abstract The landscape‐scale impacts of habitat subdivision (fragmentation per se) on biodiversity are not fully resolved. While smaller patches usually contain more species for equal total area, many implications this remain unclear. For example, do areas and larger provide equivalent value? How might change over time under differing matrix conditions? To help address these knowledge gaps, we developed an indicator relative value based a species‐individual null model. We used the to compare sets ordered in small‐to‐large large‐to‐small orders, building hierarchical Bayesian regression models test role since patch creation contrasting conditions. This allowed us assess 85 metacommunities inhabiting fragmented landscapes (1354 patches, >4500 species). expected comparable following due unpaid extinction debts, would determine direction time, harsher increasing patches. Averaged quality, probability density was mostly negative, suggesting slightly greater among pattern consistent across taxonomic groups, although amphibians reptiles were most affected, invertebrates least so.

Conversely, retain speculate that reflects ‘colonization credit’, which occur initial loss fragmentation‐sensitive disturbed landscapes. Overall, analyses support need maintain enhance area—regardless configuration—for conservation, especially long‐fragmented with matrices.

In forest regions worldwide, the extent of industrial forestry footprint challenges biodiversity conservation and calls for advanced protection ecological restoration. The efficiency protected areas needs to be improved, ecosystems need set in a state that favors biodiversity, resilience, provisioning ecosystem services. Sweden hosts large share European forests, with dominance non‐industrial ownership extensive footprint, hence strong expanded conservation, restoration, multiple‐use targets. Protection through voluntary Nature Conservation Agreements regulated Biotope Areas exists since 1990s, supported by economic compensation landowners. Across entire all ecoregions, we assessed their abundance over 30‐year period, including types, restoration practices, rotation intervals, selection tree species. These nearly 14,000 patches covering 70,000 ha are small median area 3–4 rarely larger than 20 ha. Their contribution is important, particularly southern low fragmented cover distributed among many different owners. A decreasing trend alarming these contribute representative type across landscape Sweden. Active dominates passive set‐asides; coniferous types less represented more rare species favored, practices occur, but few dominating. While recognizing important contribution, find narrow repetitive greater diversification needed improve targets forests.

Abstract There is a global call for more efficient voluntary conservation practices. Voluntary requires landowner participation, which may limit efficiency. Here, we evaluated the ecological costs and benefits of policy relative to obligatory conservation, two hypothetical scenarios randomly distributed area networks, ecologically optimized networks. The study was based on spatial prioritization maps reflecting priority forest in Central Finland. Our results suggest that networks can be relatively cost‐efficient with higher nature values better connectivity compared selected network. scored slightly than network but suffered from lower smaller size.

Recent analyses suggest that positive patch area effects on biodiversity occur ubiquitously when comparing equal-effort samples from remnant habitat patches.The mechanisms underlying the emergence of this so-called "ecosystem decay" remain poorly understood despite conservation relevance.We leverage spatially-explicit information occurrence plant species across Swiss Alps (415 plots, 668 species) to test two compatible with patch-scale ecosystem decay: (i) plots sampled within small patches might have lower than large (plot-scale decay hypothesis), and (ii) share a proportion (turnover hypothesis).We found occurs also in our system.While tended be more dissimilar, supporting turnover hypothesis, we did not find support for plot-scale hypothesis.Additionally, distance between elevational changes explain better effects.Taken together, these results indicate applications require understanding potentially underlie pattern.Patch less important previously assumed assessing landscape-scale biodiversity, because such can confused distance-decay community similarity, environmental heterogeneity, sampling effort.More broadly, findings align mounting evidence protecting as much possibleregardless whether exists continuous or fragmentedmight most effective means sustain human-dominated landscapes.

Previous studies on global carbon emissions from forest loss have been marked by great discrepancies due to uncertainties regarding the lost area and densities of different pools. In this study, we employed a new 30 m land cover dynamic dataset (GLC_FCS30D) improve assessment areas; then, combined multi-sourced stock products enhance information density. Afterwards, estimated over period 1985–2020 based method recommended Intergovernmental Panel Climate Change Guidelines (IPCC). The results indicate that continued accelerate past 35 years, totaling about 582.17 Mha leading total committed 35.22 ± 9.38 PgC. Tropical zones dominated (~2/3) their higher density greater loss. Furthermore, more than doubled in 2015–2020 (1.77 0.44 PgC/yr) compared those 1985–2000 (0.69 0.21 PgC/yr). Notably, at high altitudes (i.e., above 1000 m) tripled mountainous regions, resulting pronounced these areas. Therefore, accelerating trend indicates challenges still remain for achieving COP 26 Declaration halt 2030.
