The presence of 16SrV phytoplasmas led to a decline in hazelnuts and caused serious problems in hazelnut production in Slovenia. Sampling of various plant parts revealed that 16SrV phytoplasmas are more reliably detected in roots than in shoots. A sufficiently high concentration is important for...

Agroforestry parklands are an age-old traditional land use practice that integrates crop cultivation under scattered woody plants. This practice is widespread in West African savannas providing many essential ecological and socio-economic benefits to people such as food, fuelwood, and medicine....

The objective of this study is to produce the Soil Map of Mato Grosso do Sul using cLHS with covariates (digital elevation model, slope, curvature, horizontal distance to the drainage channel, lithology, soils, vegetation and biomes (cerrado and Atlantic forest)). The program selected 1400 points...

Objective: The sampling method of virus on food packaging surfaces was optimized. The virus recovery rate on different material surfaces was studied by simulating different scenes of virus contamination on the surfaces of frozen food packaging materials. Methods: The virus was evenly coated on the...

The quantitative assessment of habitat conservation status is a major task for European Union member states in compliance with Council Directive 92/43. One goal of the European 2030 Biodiversity Strategy is the effective management of habitats that show declining trends. While various approaches...

Sampling inventories are strategies to gather qualified information for managing urban forests, given the scarcity of budgetary resources for a complete inventory and lack of public engagement to reduce costs. However, procedures for testing sampling sufficiency can be unspecified in researches...

Protection and conservation of forests require access to information and awareness of structural features such as number per hectare and canopy cover of trees. This study aimed to select the optimal cluster sampling design in estimating the quantitative characteristics of the forest according to...

In contrast to the conventional approach of using measured yields for independent variables in a double sampling estimator, a new estimator is presented for Continuous Forest Inventory (CFI) with partial replacement that is based on projected yields for independent variables. This proposed approach ...

Being able to determine with certainty whether two wood samples derive from the same tree is important in many disciplines, especially in dendroarchaeology. In the past, a t-test threshold > 10 based on oak (Quercus sp.) was proposed for this purpose, and ever since this value has also been...

It is important to achieve estimates at the minimum cost, with no greater uncertainty than that which is appropriate for the objectives of the inventory. The aim of this study was to estimate the forest volume efficiently and accurately by sampling and analyzing the existing forest survey data,...
