Exogenous IAA application alleviated altered physiological and biochemical processes through promoting H‐ATPase and Fe chelate reductase activities in common bean (Phaseolus vulgaris L.) subjected to iron deficiency

open access: yesPlant Biology, EarlyView.
Exogenous IAA supply enhances the strategy I response in common bean under iron deficiency. Abstract Iron deficiency is a common nutritional disorder observed in calcareous soils, where its resolution by classical methods has shown its failure. However, the exploitation of certain potentialities possessed by crops (rhizosphere acidification, H‐ATPase ...

Identification of six Papilionaceae species by epidermal characteristics: Microanalysis of handcomposed mixtures Identificación de seis especies de Papilionaceae mediante características epidérmicas: microanálisis de mezclas compuestas a mano

open access: yesBoletín de la Sociedad Argentina de Botánica, 2009
The microhistological analysis quantifies the botanical composition of herbivore diets by the identification of the epidermal characters of ingested species. Many Papilionaceae form part of herbivore diets due to their high nutritive quality.

Effects on herbicides on hedgerow biodiversity [PDF]

open access: yes, 2008
Low dosages of herbicides may reduce the number of flowers on non-target plants. Effect of herbicides on flowering and on pollen and nectar production are relevant end-points for effect assessment on non-target species.

Induced defence by a root hemiparasite increases host plant resistance against future infection

open access: yesPlant Biology, EarlyView.
Infection by root hemiparasites can increase mortality of parasites during future infection, indicating induced host defence mechanisms. Abstract European grassland plants are frequently attacked by root hemiparasites. However, little is known about host defence responses to parasitism.

Input of nitrogen from N2 fixation to northern grasslands [PDF]

open access: yes, 2005
Forage legumes form N2-fixing symbioses with rhizobia and may thus make substantial contributions to the N pool in grasslands. However, to optimize their use as sources of N, it is important to elucidate the effects of management factors that influence ...

An inventory of invasive alien species in China [PDF]

open access: yes, 2012
Invasive alien species (IAS) are a major global challenge requiring urgent action, and the Strategic Plan for Biodiversity (2011–2020) of the Convention on Biological Diversity (CBD) includes a target on the issue.

Vegetation trajectories over 150 years of temporary ponds created in the Camargue delta (Southern France)

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Temporary ponds in the Mediterranean climate have a high conservation value, but many have been severely destroyed or degraded. Pond restoration and new pond creation have been engaged widely. Evaluations of the success of such operations are generally carried out over 10–15 years and show divergent results over this timeframe. In

Assessing forage mass using smartphone imagery for cereal rye under grazing conditions in Nebraska

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Managing grazing efficiency requires reliable and practical tools to estimate forage mass. Traditional methods like clipping, though accurate, are time consuming and labor intensive. In this study, two imaging tools, Canopeo and the Crop Canopy Image Analyzer (CCIA), were evaluated for their efficacy in estimating the forage mass of cereal rye
