Global warming is predicted to change the growth conditions for plants and crops in regions at high latitudes (>60° N), including Arctic. This will be accompanied by alterations composition of natural plant pest communities, as herbivorous arthropods invade these well. Interactions between previously non-overlapping species may occur cause new challenges herbivore attack. However, growing experience less herbivory compared grown lower latitudes. We hypothesize that this finding due a gradient constitutive chemical defense towards Northern regions. further higher level defensive compounds mediated defense-related phytohormone jasmonate. Because its biosynthesis light dependent, Arctic summer day can promote jasmonate accumulation and, hence, downstream physiological responses. A pilot study with bilberry (Vaccinium myrtillus) under different regimes supports hypothesis.

ABSTRACT Disruptions to functionally important symbionts with global change will negatively impact plant fitness, broader consequences for species' abundances, distribution, and community composition. Fungal endophytes that live inside leaves roots could potentially mitigate heat stress from warming. Conversely, disruptions of these symbioses exacerbate the negative impacts To better understand consistency strength warming‐induced changes fungal endophytes, we examined leaf root in three grassland warming experiments US ranging 2 25 years spanning 2000 km, 12°C mean annual temperature, 600 mm precipitation. We found experimental disrupted symbiosis between plants endophytes. Colonization tissues by septate fungi decreased response 90% 35% roots. Warming also reduced diversity changed composition leaves, but not The strength, direction, effects on varied up 75% among experiments. Finally, decoupled host metabolism decreasing correlation endophyte metabolome dissimilarity. These were strongest shorter‐term experiment, suggesting endophyte‐host function may acclimate over decades. Overall, warming‐driven disruption structure suggests this be a reliable mechanism promote resilience ameliorate responses under change.

Abstract Accidental introductions of biological weed control (BWC) agents (i) offer opportunities to assess host use with a potentially broader fundamental host‐range than those approved for field release directly in target areas; (ii) urge national authorities rapidly respond as they may threaten native species or crops, and by this (iii) help advancing post‐release studies, neglected aspect BWC.

Abstract Plant invasions driven by global environmental changes (e.g. nutrient enrichment) increasingly threaten natural ecosystems. It is unclear whether reducing nitrogen (N) inputs helps to mitigate plant in Using ongoing, landscape‐scale N reductions the Yangtze River, we combined spatiotemporal surveys before and after manipulative experiments explore how contributed native community recovery estuarine marshes degraded invasions. We found that Phragmites australis patches gradually recovered Spartina alterniflora ‐invaded inputs. The competitive advantage of S. over P. decreased with reduction, shifting outcomes away from exclusion their coexistence. Synthesis applications . Our findings reveal reversal enrichment may shift ecosystems being more susceptible invasion toward successional recovery, offering a promising approach for facilitating invaded These have important implications restoring ecosystems, especially as change escalates extent impact invaders exacerbating current new ones.

Abstract Climate change is predicted to increase the occurrence of extreme weather events such as heatwaves, which may thereby impact outcome plant-herbivore interactions. While elevated temperature known directly affect herbivore growth, it remains largely unclear if indirectly influences performance by affecting host plant they feed on. In this study, we investigated how transient exposure high herbivory-induced defenses at transcript and metabolic level. To end, studied interaction between potato ( Solanum tuberosum ) plants larvae tuber moth Phthorimaea operculella under different regimes. We found that P. grew heavier on leaves co-stressed insect herbivory than pre-stressed alone. also observed treatments altered phylotranscriptomic patterns upon herbivory, changed from an evolutionary hourglass pattern, in transcriptomic responses early late time points after elicitation are more variable ones middle, a vase pattern. Specifically, transcripts many genes defense stage were suppressed HT treatment, whereas those intermediate peaked earlier. Additionally, impaired induction jasmonates compounds herbivory. Moreover, using jasmonate-reduced (JA-reduced, irAOC -elevated (JA-Ile-elevated, irCYP94B3s plants, showed suppresses JA signaling mediated plant-induced attack. Thus, our study provides evidences reprograms herbivores.

For its control, planthopper Megamelus scutellaris Berg (Hemiptera: Delphacidae), phloem feeder also has been introduced USA Africa. Considering predicted climate change scenarios, understanding their impacts on biological control agents crucial. An intriguing yet scarcely explored subject, effect climatic changes obligate endosymbionts associated with sap-sucking feeders. Planthoppers establish an relationship yeast-like symbiotes (YLS), unicellular fungal microorganisms that play important role development, providing missing nutrients diet. increased atmospheric CO2 affects chemical composition, this might have direct impact insect host number YLS.
