Ancient Wheat Species Can Extend Biodiversity of Cultivated Crops [PDF]

open access: yes, 2011
Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year ...

Wild bee diversity and land use: A case study in a mountain agroecosystem of the Serranía de Ronda, southern Spain

open access: yesInsect Conservation and Diversity, EarlyView.
Orchards supported the highest wild bee diversity and functional diversity, highlighting their role in maintaining bee communities in Mediterranean agroecosystems. Landscape heterogeneity positively influenced functional evenness and dispersion of wild bee communities, underscoring the importance of diverse landscapes for bee conservation. The presence

Spider fauna associated with wheat crops and adjacent habitats in Buenos Aires, Argentina Araneofauna asociada a cultivos de trigo y hábitats adyacentes en Buenos Aires, Argentina

open access: yesRevista Mexicana de Biodiversidad, 2011
A census of spiders was undertaken in winter wheat fields of Buenos Aires province, Argentina, as well as from their margins and from wheat stubble. Spiders were collected weekly over 3 consecutive years using entomological sweeping and pitfall traps ...

Dryland maize yields and water use efficiency in response to tillage and nutrient management practices in China [PDF]

open access: yes, 2009
Rainfed crop production in northern China is constrained by low and variable rainfall. This study explored the effects of tillage and nutrient management practices on maize (Zea mays L.) yield and water use efficiency (WUE), at Shouyang Dryland Farming ...

Application of Genomic Random Regression Models for Genetic Parameter Estimations of Female Fertility Traits in Different Parities in German Holsteins

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The aim of the present study was to infer genetic (co) variance components and to estimate parity‐specific breeding values for the female fertility traits non‐return rate after 56 days, the interval from calving to first service and days open by applying random regression models on a time‐dependent parity scale. In this regard, we considered a

Feeding Preference and Foraging Behaviour of Eriopis connexa on Two Aphid Species

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Aphids are phloem‐feeding insects that cause both direct and indirect damage to crops, reducing agricultural productivity. Among the available pest control strategies, biological control using natural enemies is a sustainable and effective approach. The ladybird Eriopis connexa (Germar, 1824) is a generalist predator known for its voracity and

A cover crop alters the trophic positions of generalist predators in the litter of a banana agroecosystem [PDF]

open access: yes, 2010
Generalist predators can play an important role in agroecosystems by controlling herbivores via top-down effects. As cover crops are increasingly used in agroecosystems, the effects of this resource on generalist predator diet need to be evaluated.

‘PULSE FICTION’: Development of Slightly Processed Pulse‐Based Foods and Recipes to Meet the Needs of Consumers and the Agricultural Sector and Improve Food Sustainability

open access: yesNutrition Bulletin, EarlyView.
ABSTRACT Pulses offer significant nutritional and environmental benefits and are useful components of healthier, more sustainable diets and global food security. However, their consumption in France remains low and below the world average. Farmers face economic and technical challenges in diversifying crops, and current domestic production is ...

Cold hardiness mechanisms and modeling: existing approaches and future avenues

open access: yesNew Phytologist, EarlyView.
Summary Cold hardiness models are useful tools to predict cold damage in plants, such as those produced by unseasonal temperature cycles or by increased cold exposure. Although development of these models started about five decades ago, their applications remain limited.
