“…As the ADF and NDF contents increases, DMI, DDM and subsequently nutritive value declines due to increasing fibre (Abaye et al, 2009;Zhai et al, 2018). As noted herein, the high CP and low ADF and NDF contents of forages are generally associated with increased energy value or good forage quality (Kirilov et al, 2016;Zhai et al, 2018). Therefore, the highlighted weeds may be relative adequate to meet the nutritional needs of grazing livestock (Gutiérrez et al, 2008;Bunton et al, 2020;Maduro Dias et al, 2020) depending on the ratio of weeds in the rangeland (Uzun and Ocak, 2019).…”

“…The results on cell wall constituents showed that the weeds contained favourable levels of NDF, ADL, ADF and HC and, thus, a good and valuable source of these nutrients, as were reported by Khan et al (2017). Although protein requirement varies with each type and stage of life of grazing animals (Abaye et al, 2009;Kirilov et al, 2016), the dietary adequate-protein level required for maximal growth and activity of ruminal microorganisms is higher than 7% CP (Sampaio et al, 2010;Maduro Dias et al, 2020). The CP content of all the weeds in the present study had more excellent than this value.…”

In this study, common weed species (Anthemis sp., Anthemis tinctoria L., Pilosella hoppeana Schultes, Doranicum orientale Hoffm, Muscari neglectum Guss. ex Ten., Ornithogalum armeniacum Baker, Ornithogalum narbonense L., Ornithogalum wiedemannii Boiss., Anchusa azurea Miller, Echium plantagineum L., Echium vulgare L., Ajuga orientalis L., Stachys germenica L., Juncus sp., Anacamptis pyramidalis L., Ophrys apifera Huds., Carex panicea L., Ranunculus sp., Hypericum perforatum L., Primula elatior L. Hill., and Galium rotundifolium L.) of the rangelands of Akdağ mountains, Samsun were evaluated by principal component analysis (PCA) and cluster analysis (CA). These species were collected at least three times in two consecutive years. The proximate nutrients (organic matter, ash, crude protein, ether extract, neutral and acid detergent fibre, non-fibrous carbohydrate and hemicellulose), neutral detergent fibre properties (nitrogen-free neutral detergent fibre and in vitro neutral detergent fibre digestibility), and forage quality indicators (digestible dry matter, dry matter intake, metabolizable energy, net energy lactation, estimated net energy, total digestible nutrients, relative feed value, and relative forage quality) were assessed by chemical analysis and empirical equations. There were significant variations in the nutritional dynamics among the weed species. The PCA results demonstrated a relationship between the dietary dynamics assessed. Component 1 (65.5%) and component 2 (14.5%) described 80.0% of the total variation, with eigenvalues of 11.788 and 2.609 in the weed species, respectively. The loadings plot of components shows that most forage quality indicators were distributed to Quadrant 1 and Quadrant 4. Three clusters are observed from the CA for the weeds with significant linkage distance, indicating relatively high independence for each cluster. Due to high variation in their nutritional dynamics, the weed species (P. elatior, O. wiedemannii, O. narbonense, and G. rotundifolium) were more similar on component 1 ordination and in Cluster 1 of the dendrogram. In conclusion, our results suggest that the highlighted species have significant potential for grazing livestock as forages and could fulfilling the possible forage gap in the grazing system.

“…The richest plant diversity we find in the Early Bronze Age (∼4.1-3.9 kyr BP), where elm ( Ulmus ), spruce ( Picea ), and maple ( Acer ) are the dominant tree species, accompanied by oak ( Quercus ) and beech ( Fagus ); leaves of these species also have high nutritional value and historically were favoured fodder( 42 ). In this same context, we find a high abundance of wheat ( Triticum ), sedges (Carex ) that most often is found in wetlands, and heather ( Calluna ) which typically grows on well-drained soils.…”

“…This could be a possible indication of seasonality, where animals were brought to the area to graze on select leaf fodder available in the autumn or winter. The later presence of Lamium (∼5.3 kyr BP), typically an early seasonal succession weed, is interesting as deadnettle ( Lamium purpureum ) can be palatable but closely related henbit ( Lamium amplexicale ) is toxic for sheep ( 42 , 71 ). Further investigation of DNA from the Late Neolithic may indicate strong control in grazing combined with adjustment and broadening of seasonality through time.…”

Central European forests have been shaped by complex human interactions throughout the Holocene, with significant changes following the introduction of domesticated animals in the Neolithic (∼7.5 – 6.0 kyr BP). However, understanding early pastoral practices and their impact on forests is limited by methods for detecting animal movement across past landscapes. Here we examine ancient sedimentary DNA (sedaDNA) preserved at the Velký Mamuťák rock shelter, in northern Bohemia (Czech Republic), which has been a forested enclave since the early Holocene. We find that domesticated animals, their associated microbiomes, and plants potentially gathered for fodder, have clear representation by the Late Neolithic, around 6.0 kyr BP, and persist throughout the Bronze Age into recent times. We identify a change in dominant grazing species from sheep to pigs in the Bronze Age (∼4.1 – 3.0 kyr BP) and interpret the impact this had in the mid-Holocene retrogressions that still define the structure of Central European forests today. This study highlights the ability of ancient metagenomics to bridge archaeological and paleoecological methods and provide an enhanced perspective on the roots of the Anthropocene.
