Sward Height in Grazing Management: Vertical Profiles in Forage Quality [PDF]
Vertical and temporal trends in herbage yield and quality were assessed in a study sown in 1989 near Elora, Ontario. In a replicated field trial with 0.1 ha paddocks, Hereford heifers rotationally grazed 2 swards to each of 2 residual grazing heights ...

Host plant use is driven by microclimate not nutritional quality in a grassland butterfly
Ecological Entomology, EarlyView.Small Copper butterflies (Lycaena phlaeas) choose to lay eggs on host plants growing in warmer microclimates, despite lower nitrogen content. Bare ground created by European Moles increases host plant temperatures and weakens the negative relationship between nitrogen content and microclimatic warmth.

The Independent Effects of Sward Height and Bulk Density on the Bite Parameters of Romney Ewes and Red Deer Hinds [PDF]
The independenl effects of sward height (I, 2, 3, 5 and 8 cm) x bulk density (0.65, 1.30, 2.90 mg DM/cm3) variation on the ingestive behaviour of Romney ewes and Red deer hinds were examined in seedling swards which simulated a leafy grass sward of low ...

Insect Conservation and Diversity, EarlyView.Sheep and cattle grazing significantly shape ant and ground beetle species composition in Mediterranean cork oak woodlands, promoting higher diversity by increasing habitat heterogeneity. Ground beetles and ants reflect changes in grazing regimes, with sheep‐grazed areas showing the highest diversity, highlighting their utility in ecosystem monitoring.

Journal of Fish Diseases, EarlyView.ABSTRACT Disease outbreaks and the associated reliance on antibiotics pose major constraints to the sustainability of modern aquaculture. As regulatory pressures increase and consumer demand shifts toward residue‐free production, diverse biological interventions are gaining prominence as viable alternatives to chemotherapeutics.

Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings
Journal of Integrative Plant Biology, EarlyView.Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.

Journal of Integrative Plant Biology, EarlyView.Pan‐genome analysis reveals that high‐altitude Rhododendron species resist alpine cold stress by rapidly sensing and engaging the chilling response pathway and genes that directly and indirectly protect the plant from UV radiation. Heritable genomic features such as long terminal repeats contribute to the adaptive diversification of Rhododendron ...
