Historic disturbance events overruled climatic factors as drivers of ruderal species distributions in the Scandinavian mountains

open access: yesNordic Journal of Botany, EarlyView.
The contemporary interaction of climate and disturbance drives vegetation composition and species distribution shifts, making their respective roles difficult to disentangle. This study describes the long‐term ruderal plant species distributions along the ‘Rallarvägen' in Abisko, subarctic Sweden.

Arbuscular mycorrhizal fungal families and exploration‐based guilds exhibit distinct responses to long‐term N, P and K deficiencies and imbalances

open access: yesNew Phytologist, EarlyView.
Summary Many agroecosystems face nitrogen (N), phosphorus (P) or potassium (K) deficiencies due to imbalanced or insufficient nutrient replenishment after biomass harvest. How this affects the symbiosis between plants and arbuscular mycorrhizal fungi (AMF) and the abundance of exploration‐based AMF guilds (rhizophilic, edaphophilic and ancestral ...

Fascinating single‐cell red algae: models for evolution and adaptation

open access: yesNew Phytologist, EarlyView.
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

Accounting for Cross‐Country Differences in Output Per Worker: A Sectoral CES Perspective

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT The standard macroeconomic literature suggests that richer countries employ more productive technologies. Removing technological disparities between countries would hence narrow the substantial variation in output per worker across countries.

Alleles From Crop Wild Relatives Accumulated by Long‐Term Adaptation to Low‐Input Environments Contribute to Yield Advantages in Wheat (Triticum aestivum)

open access: yesPlant Breeding, EarlyView.
ABSTRACT Increasingly variable climate conditions are affecting crop production, leading to greater yield fluctuations, which in turn are impacting global food security. Introducing alleles from regions where the expected stress conditions occur, so‐called exotic alleles, could serve as a means to mitigate these effects. We examined the value of exotic

On Community Development Research and Practice: Towards a Reflexive Approach

open access: yesSocial Policy &Administration, EarlyView.
ABSTRACT The lack of an established policy framework by government in Northern Ireland for community development, within the contested objectives of an enforced coalition, mirrors theoretical perspectives that see community development as a contested concept. In contrast, a research programme working with community development organisations in Catholic

Green leaf manuring and green manuring

Madras Agricultural Journal, 1950
The terms "Green Leaf Manuring" and "Green Manuring" convey technically different meanings, though the ultimate object is the same in both cases. The practice of lopping green leaves from trees like Pungam, Neem etc., and applying them to paddy fields is called "Green Leaf Manuring." When crops like Pillipesra, Daincha, Sunnhemp, Indigo and Wild Indigo

Green manuring

Outlook on Agriculture, 1984
Green manuring can be defined as the growth of a crop for the specific purpose of incorporating it into soil while green, or soon after maturity, with a view to improving the soil and benefiting subsequent crops. This definition excludes the incorporation of crop residues and short leys which are grown as forage or conservation crops.
