THE DETERMINANTS OF CEREAL CROP DIVERSITY ON FARMS IN THE ETHIOPIAN HIGHLANDS [PDF]
On farm conservation of crop diversity entails policy challenges, especially when the diversity of crops maintained on farms has both inter-specific (among crops) and infra-specific (within a crop) components.

Frontiers in Ecology and EvolutionThe abundance and species composition of adult ladybird communities (Coleoptera: Coccinellidae) were investigated on two congeneric trees, native Norway spruce (Picea abies) and the introduced blue spruce (Picea pungens), at four locations in Slovakia ...

Molecular Oncology, EarlyView.Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Effect of Alley Cropping on Crops and Arthropod Diversity in Duzce, Turkey
Journal of Agronomy and Crop Science, 2003 AbstractThe influence of alley cropping practices on trees, agricultural crops and arthropod diversity was studied in Duzce, Turkey. Six replications of three crops, maize (Zea mays L. var. rugosa), beans (Phaseolus vulgaris L.) and zucchini (Cucurbita pepo L.), were planted in the alleyways between rows of hybrid poplar [Populus euramericana (Dode ...

Demand and Supply of Crop Infraspecific Diversity on Farms: Towards a Policy Framework for On-Farm Conservation [PDF]
Interest is increasing worldwide in on-farm conservation as a component of a strategy to conserve crop genetic resources. On-farm conservation may require outside support to small-scale farmers in areas of crop domestication and diversity.

The East Asiatic region of crop plant diversity
, 2019 Crop plant diversity of E Asiatic region (China, Japan and Korea Peninsula) is extremely interesting because of the region's high level of plant diversity resources and long history of cultivation and domestication, while an inventory of crop plant ...

Molecular Oncology, EarlyView.LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

CEACAM1 participation in breast cancer progression
Molecular Oncology, EarlyView.In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Uprooting Diversity? Peasant Farmers’ Market Engagements and the on-Farm Conservation of Crop Genetic Resources in the Guatemalan Highlands [PDF]
The long-term security of the global food supply is contingent upon the on-farm conservation of crop genetic diversity. Without it, food crops lack the ability to evolve in the face of new pests, emerging plant diseases, and changing environmental ...

Data from: Crop rotational diversity enhances belowground communities and functions in an agroecosystem [PDF]
, 2015 Biodiversity loss, an important consequence of agricultural intensification, can lead to reductions in agroecosystem functions and services. Increasing crop diversity through rotation may alleviate these negative consequences by restoring positive ...
