Saponins from <em>M. lupulina</em> tops were investigated for the first time. Eight aglycones were found in the acid hydrolysates of saponins. All of the aglycones were isolated. On the basis of chromatography, mass spectrometry and infrared spectrometry the aglycanes were identified as soyasapogenols B, C, D, E, F and medicagenic acid. Two

Abstract Introduction Process‐based restoration is novel in livestock production systems of the Northern Great Plains (NGP), and limited region‐specific evidence can impede adoption. We investigated the effects of methods such as beaver dam analogs (BDAs) on NGP plant communities.

Biodiversity and soil type modulate the effect of plastic contamination on soil functioning
Our findings show that the negative effects of plastic contamination on soil functioning strongly depend on soil type and can be partly alleviated by plant diversity. In sandy soils, diverse plant communities buffered functional losses under plastic stress, whereas in clayey soils the benefits of diversity were suppressed.

Optimizing seeding ratios of field pea–brown mustard intercrops in Atlantic Canada
Abstract Intercropping is a promising approach for ecological intensification that can enhance productivity and agroecosystem services. This study evaluated the agroecological performance of field pea (Pisum sativum) and brown mustard (Brassica juncea) intercropping across seeding ratios (0.5×, 1.0×, and 1.5× the recommended rates; 100 seeds m−2 ...

Medicago lupulina (black medick).
Abstract Medicago lupulina is an annual or short-lived perennial herb with a wide native range across Africa, Asia and Europe. It is a common weed in disturbed areas, wastelands, roadsides, abandoned pastures and forest margins. It is a nitrogen-fixing species cultivated for forage and used as a soil improver; it is also a seed ...

Urban Microfarms: Hot or Cold Spots for Plants and Soil Biodiversity?
Investigation of soil and plant biodiversity in urban microfarms on the ground and on rooftops. ABSTRACT Urban agriculture plays a key role in urban ecosystems functionality and resilience, and can take many forms: allotment gardens, community garden or urban microfarms.

Medicago lupulina lines with defects in the development of efficient arbuscular mycorrhiza [PDF]
Background. The work is aimed to solve actual problems in biology of arbuscular mycorrhiza (AM). Currently, a lot of mutants had been obtained in various plant model objects with defects in genes controlling AM development, however, the mechanisms controlling development of effective AM symbiosis are still unclear. Materials and methods.

Earlier reproductive phenology of restored grasslands
Abstract Introduction Plants introduced to degraded ecosystems during restoration efforts often face novel environmental conditions. Consequently, plant functional traits can differ between restored and reference sites, even within the same species. Studies on such intraspecific variation mainly focused on vegetative traits, while the timing of life ...

Plant‐Pollinator Interactions in Grasslands Established on Arable Land
We compared plant‐pollinator networks in newly established and old, permanent grasslands in a Central European agricultural landscape. Newly established grasslands showed higher pollinator visitation frequency and diversity per plant species, especially for solitary bees and syrphids, with a comparable network structure to old grasslands.

Two pure saponin fractions from the tops of <em>M. lupulina</em> were isolated and characterized. The fractions named Ma and Ss varied in composition and biological activity. It was shown by TLC that fraction Ma contained 5 components. In the acid hydrolysates of that fraction only one aglycone (medicagenic acid) and 4 sugars: rhamnose ...
