Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

Evolutionary-thinking in agricultural weed management [PDF]

open access: yes, 2009
Agricultural weeds evolve in response to crop cultivation. Nevertheless, the central importance of evolutionary ecology for understanding weed invasion, persistence and management in agroecosystems is not widely acknowledged.

Is quinoa‐farming sustainable in marginal environments? Social, economical and environmental aspects

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Quinoa (Chenopodium quinoa Willd.) is an Andean grain crop introduced as a novel crop to many parts of the world in recent years. Recognized for nutritious seeds and high abiotic stress tolerance, it has been promoted as an element of climate‐resilient agriculture, particularly in marginal environments.

Diverse genetic mechanisms underlie worldwide convergent rice feralization

open access: yesGenome Biology, 2020
Background Worldwide feralization of crop species into agricultural weeds threatens global food security. Weedy rice is a feral form of rice that infests paddies worldwide and aggressively outcompetes cultivated varieties. Despite increasing attention in

Complementary gene controlling the black hull phenotype and phenolics and flavonoids content in weedy rice (Oryza sativa f. spontanea) from northeastern Thailand [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2019
A complementary gene black seed hull 4 (Bh4 and Phr1) is a hull color candidate gene that causes a black pigmentation in the ripened hulls of rice. The relationship between Bh4 and Phr1 in the black hull phenotype was elucidated previously.

Rapid evolution of morphology and adaptive life history in the invasive California wild radish (Raphanus sativus) and the implications for management. [PDF]

open access: yes, 2009
Understanding the evolution and demography of invasive populations may be key for successful management. In this study, we test whether or not populations of the non-native, hybrid-derived California wild radish have regionally adapted to divergent ...

The evolution of flowering strategies in US weedy rice [PDF]

open access: yesAmerican Journal of Botany, 2014
• Premise of the study: Local adaptation in plants often involves changes in flowering time in response to day length and temperature. Many crops have been selected for uniformity in flowering time. In contrast, variable flowering may be important for increased competitiveness in weed species invading the agricultural environment.

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

open access: yesPeople and Nature, EarlyView.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Poly(Hydroxybutyrate‐Co‐Hydroxyvalerate)/Thermoplastic Starch Blends for Application in Biodegradable Mulch Films

open access: yesPolymer Engineering &Science, EarlyView.
Poly(hydroxybutyrate‐co‐hydroxyvalerate)/thermoplastic starch blends, produced by melt processing, showed improvements in mechanical properties and water vapor transmission barrier performance, which can help control excessive water evaporation from the soil, thus contributing to pH and moisture regulation.
