Turning Up the Heat: More Persistent Precipitation Regimes Weaken the Micro‐Climate Buffering Capacity of Forage Grasses During a Hot Summer

Simon Reynaert; Ivan Nijs; Tommy D'Hose; et al. Global Change Biology 2025. doi:10.1111/gcb.70078

Other claims from this paper (6)

Intervention effect Warming worsened the negative effect of persistent precipitation regimes on forage grass productivity.
Intervention effect Warming worsened physiological plant stress under persistent precipitation regimes.
Intervention effect Warming with persistent precipitation regimes induced more extreme soil drought and elevated microclimatic temperatures.
Observation Permanent grassland soils with elevated organic carbon buffered forage yields.
Association Higher yielding varieties buffered soil surface and canopy temperatures more proficiently.
Recommendation The authors recommend incorporating temperature buffering traits in climate proof forage grasslands.

Functional thresholds of plant resistance and recovery to drought

Johannes Ingrisch; Nikolaus Umlauf; Michael Bahn 2021. doi:10.5194/egusphere-egu21-8333

Other claims from this paper (7)

Intervention effect Drought intensity had nonlinear effects on productivity during resistance and recovery.
Intervention effect Moderate drought caused a threshold downregulation of gross primary productivity and plant height.
Intervention effect A second drought threshold produced steep declines in NDVI and leaf water content.
Intervention effect High drought intensity stimulated productivity and regrowth during recovery.
Intervention effect Severe prior drought led to biomass overproduction up to 100%.
Association Overcompensation after intense drought was more pronounced in Plantago than Dactylis.
Intervention effect The highest drought intensities suppressed Plantago recovery.

Other claims from this paper (7)

Observation Leaf trichome density and size varied among the grasses.
Association Agropyron trichomes appeared associated with resistance to Labops nymphs.
Association Trichomes had no relation with adult black grass bug feeding behavior.
Association Nymphs preferred species with intermediate sized trichomes based on damage.
Observation Adult bugs did not discriminate in feeding.
Intervention effect Field grown plants developed more trichomes per unit leaf area than greenhouse plants.
Intervention effect Field grown plants appeared to have thicker surface waxes than greenhouse plants.
