Spider diversity in a disturbed forest landscape highlights the importance of management heterogeneity

Insect Conservation and Diversity, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 30, 2025

Abstract Anthropogenic climate and land use change pose threats to biodiversity. For example, timber production is altering forest ecosystems worldwide, often resulting in climate‐sensitive monocultures. In central Europe, ongoing has resulted a large‐scale dieback of spruce plantations, raising concerns about the appropriate management such sites. Here, we investigated direct indirect effects on epigeal spider diversity disturbed, spruce‐dominated landscape western Germany. We compared five strategies evaluated impact various environmental variables taxonomic as well community functional composition. Forest directly affected diversity, with lowest values found stands highest salvage‐logged succession Spider abundance was negatively related canopy closure, positively deadwood occurrence on‐site at scale. Community composition differed strongly among regimes, number specialists occurring open species clear cuts. Our results highlight role non‐intervention sites refuges for spiders highly disturbed landscape, while showed overall diversity. Based distinct assemblages our stress importance heterogeneity should therefore be planned rather than stand‐scale. By applying intervention strategies, monocultures may transformed into diverse landscapes beneficial both biodiversity forestry.

Abstract Forests can provide important nature-based solutions to climate change by retaining and sequestering large amounts of carbon dioxide from the atmosphere. But they will also have adapt inevitable consequences a warming atmosphere, which threaten health, productivity, stability many forest regions. In protected areas most multipurpose forests, maintaining continuity species habitats over time space facilitate inherent capacity ecosystems adjust through dispersal adaptive filtering. Prioritizing high-carbon reservoirs (old-growth peatlands) for protection, especially in locations expected persist under changing climate, support both mitigation biodiversity conservation. Ecosystem transformations response may be acceptable, although domination invasive exotic is generally undesirable. Tree-species diversification has benefits all forests.

Estimating Forest Variables for Major Commercial Timber Plantations in Northern Spain Using Sentinel-2 and Ancillary Data

Forests, Journal Year: 2024, Volume and Issue: 15(1), P. 99 - 99

Published: Jan. 4, 2024

In this study, we used Spanish National Forest Inventory (SNFI) data, Sentinel-2 imagery and ancillary data to develop models that estimate forest variables for major commercial timber plantations in northern Spain. We carried out the analysis two stages. first stage, considered plots with without sub-meter geolocation, three pre-processing levels images machine learning algorithms. most cases, geometrically, radiometrically, atmospherically topographically (L2A-ATC) corrected random algorithm provided best results, topographic correction producing a greater gain model accuracy as average slope of increased.

Perception of Locals on Multiple Contributions of NTFPs to the Livelihoods of Forest Fringe Communities in Ghana

Forests, Journal Year: 2024, Volume and Issue: 15(5), P. 861 - 861

Published: May 15, 2024

Forest-dwelling residents frequently collect non-timber forest products (NTFPs) for various reasons, such as food, medicine, firewood, religious or handicrafts. This study examines the multiple benefits derived from NTFPs and how they contribute to livelihoods of Ghanaian communities alleviate poverty. Resources services provided by have an essential role in providing economic, nutritional, medicinal, cultural, environmental benefits. diverse range locals collect, chewing sticks, games, herbs, honey, leaves, mushrooms, pestles, raffia palms, snails, straws. In addition serving different purposes, these income generation, food security, health care, cultural practices, protection environment.

Biodiversity Within and Beyond the Native Distribution of Tree Species: The Case of Pinus nigra Forests in Europe

ABSTRACT Aim Forests dominated by non‐native trees are becoming increasingly common. However, their impact on biodiversity remains uncertain, with a debate whether they represent ‘green deserts’ or secondary habitats for biodiversity. We addressed this question evaluating the patterns and ecological drivers of taxonomic functional understory diversity between black pine ( Pinus nigra ) forests within outside its native distribution range.
