Assessment of the N- and P-Fertilization Effect of Black Soldier Fly (Diptera: Stratiomyidae) By-Products on Maize
(2020-09-22)
To meet the growing demand for an alternative animal protein source, the Black Soldier Fly (BSF) (Hermetia illucens) industry is expanding. Thus, the valuation of its byproducts, foremost BSF frass, is getting more economic and ecological weight. Three different residues, BSF frass, larval skins, and dead adult flies, were compared with a mineral and an organic commercial fertilizer in a pot trial with maize (Zea mays L., [Poales: Poaceae]). byproducts were applied in three nutrient-based application rates (180; 215 ...

Morphologically similar but not closely related: the long-sporedspecies of Subulicystidium (Trechisporales, Basidiomycota)
(2020-06-06)
Species boundaries and geographic distribution of corticioid fungi (resupinate Basidiomycota) are often poorly known. Ourrecent study onSubulicystidiumshowed that species diversity in this genus is at least twice as high as previously recognized. Thisre-estimation of the species diversity was based on a study of only a part of the genus. The present study sheds light on molecularand morphological diversity of three more species. We generated 27 ITS and 24 28S nuclear ribosomal DNA sequences from 49specimens labelled ...

Comparison between Hyperspectral Imaging and Chemical Analysis of Polyphenol Oxidase Activity on Fresh-Cut Apple Slices
(2020-06-29)
The assessment of the quality of fresh-cut apple slices is important for processing, storage, market value, and consumption. Determination of polyphenol oxidase activity (PPO) in apples is critical for controlling the quality of the final product (i.e., dried apples and juices). Hyperspectral imaging (HSI) is a nondestructive, noncontact, and rapid food quality assessment technique. It has the potential to detect physical and chemical quality attributes of foods such as PPO of apple. The aim of this study was to ...

Mapping Invasive Lupinus polyphyllus Lindl. in Semi-natural Grasslands Using Object-Based Image Analysis of UAV-borne Images
(2020-08-07)
Knowledge on the spatio-temporal distribution of invasive plant species is vital to maintain biodiversity in grasslands which are threatened by the invasion of such plants and to evaluate the effect of control activities conducted. Manual digitising of aerial images with field verification is the standard method to create maps of the invasive Lupinus polyphyllus Lindl. (Lupine) in semi-natural grasslands of the UNESCO biosphere reserve “Rhön”. As the standard method is labour-intensive, a workflow was developed to ...

Social dynamics of values, taboos and perceived threats around sacred groves in Kurdistan, Iran
(2020-11-09)
1. Sacred groves are important for the conservation of biodiversity in the Middle East, as more formal approaches to protected areas have often failed in this global biodiversity hotspot.
2. This study aims to identify the most important social values, taboos and perceived threats around sacred groves in the Kurdistan province of Iran. We test whether values, taboos and perceived threats are lost in transmission across generations, with increased urbanisation, and with modernising livelihoods.
3. Our survey of 205 ...

Genetic diversity and differentiation of Olea europaea subsp. cuspidata (Wall. & G.Don) Cif. in the Hajar Mountains of Oman
(2020-10-04)
Olea europaea subsp. cuspidata (Wall. & G. Don) Cif. is one of the six subspecies important for domestication of olive described as having valuable breeding traits. It is distributed from South Africa to the Middle East and the Mediterranean region to China mainly at mid to high altitudes with adequate precipitation. The currently rather fragmented Olea europaea subsp. cuspidata populations likely represent outposts of a formerly larger and more connected area and are hence vulnerable to additional stresses such as ...
