In agricultural landscapes, uncultivated habitat patches may have a focal role in supporting communities of ecosystem service providers. However, little is known on the variances among different types providing resources and maintaining populations these beneficial organisms. We studied wild bee natural semi-natural embedded semi-arid Mediterranean landscapes. investigated effects local- landsc...

This study examined the soil cover and state of natural grass stand saline erosion-prone lands in valley gully system Sukhi Yaly River. Low-productive are located on slopes bottoms gullies, micro-depressions lowland floodplain meadows. Plant groups associated with such soils characterised by low species diversity a lack valuable for fodder. The article presents results research improvement low-...

Beekeepers experience high annual losses of colonies, with environmental stressors like pathogens, reduced forage, and pesticides as contributors. Some factors, nutritional stress from flower abundance or diversity, are more pronounced in agricultural landscapes where extensive farming limits pollen availability. In addition to affecting other aspects colony health, quantity quality available i...

Forages that accumulate excessive molybdenum (Mo) from excessive land application of Mo can cause molybdenosis, a copper (Cu) induced deficiency in ruminants. Limited information is available on the effect of land-applied biosolids, Mo content, and quality of winter wheat forage (Triticum aestivum L.). The objectives of this study were (1) to determine the effect of biosolids application on tis...

Forage availability is sometimes limited because of poor growing conditions or because of insufficient land base on individual farms. In addition, forage fiber can limit feed intake, particularly for high producing cows, and forage quality is highly variable. Therefore, there is continual interest in alternatives to forages in diets for dairy cows. Decreasing the forage content of diets require...

Fenugreek (Trigonella foenum-graecum L.) is used as medicinal plant in many Asian countries and has been reported to have forage quality similar to alfalfa. Fenugreek is an annual crop and may have the potential to diversify forage production systems in the central High Plains. This study evaluated forage dry matter (DM) production and the nutritive value of three fenugreek cultivars as influen...

There is a severe shortage of knowledge of bee biogeography. Some former studies have highlighted a link between bee diversity and xeric ecosystems, but we know practically nothing of the macro-ecological factors driving bee diversity. The present study aims to analyse the main macro-ecological factors driving bee species-richness in the Saharan region. Our dataset includes 25,000+ records for ...
