Article Synopsis
- Recent droughts are worsening and expected to affect forest ecosystems more frequently and intensely due to climate change.
- Research shows that having more tree species in a plantation can reduce the stress on trees during drought events, reflected by changes in leaf carbon and nitrogen isotopes.
- Higher tree species richness leads to lower drought stress (lower leaf δC) and changes in nitrogen cycling during drought (higher leaf δN), indicating that diverse tree plantations might perform better under severe drought conditions.
Plant diversity effects on community productivity often increase over time. Whether the strengthening of diversity effects is caused by temporal shifts in species-level overyielding (i.e.

- Climate change is making droughts (periods without rain) happen more often and for longer periods of time, which is bad for ecosystems.
- Scientists did a big experiment in many places around the world to see how one year of drought affects grasslands and shrublands.
- They found that extreme drought can reduce plant growth much more than expected, especially in dry areas with fewer types of plants, showing that these places are more at risk.
The sensitivity to stress and its impact on immunity are supposedly related to a fish's personality. In the present study, European perch (Perca fluviatilis) were exposed to an open-field and a novel-object test to identify distinctive shy and bold individuals. This series of cognitive tests revealed clear differences between proactive individuals with pronounced exploration behavior (bold personality) and reactive individuals that took a freeze-hide position (shy personality).

- The study explores the potential of replacing fishmeal with defatted black soldier fly meal in pikeperch aquafeeds, assessing its effects on growth, nutrient digestibility, fillet quality, and sustainability over an 84-day trial.
- Results showed that pikeperch fed diets with lower inclusion of insect meal (H0, H9, H18) performed better in growth, while H18 had lower organ-somatic indices, indicating variations in health metrics between groups.
- The inclusion of insect meal negatively impacted nutrient digestibility and fish fillet quality, especially reducing n-3 fatty acids while increasing n-6 fatty acids, but concurrently lowered the environmental footprint of fish farming.
