“…By contrast, in the present study, moor grass biomass was not significantly affected by Quercus root exudates. This is at variance with some studies reporting an allelopathic effect of Quercus sp from different regions on understorey species (Li et al, 2007). Callaway et al (1991) identified an allelopathic property of adult Quercus root exudates that inhibited understorey productivity in woodlands.…”

“…However, such inhibitory effects could be caused by allelochemicals interfering with physiological and biochemical processes in target species (Weir et al 2004;Gniazdowska and Bogatek 2005;Blanco 2007). Indeed, it has been reported that the inhibition of germination may be the consequence of the inhibition of water uptake, enzyme activity and increased abscisic acid content (Guang-de et al 2007;Turk and Tawaha 2003). Two years earlier, Muscolo et al (2001) reported that the inhibition of seed germination in Pinus laricio was attributed to a disruption of the activity of metabolic enzymes that are involved in glycolysis (first step in dark respiration) and the oxidative pentose phosphate pathway (OPPP).…”

Gas chromatography-flame ionisation detection (GC-FID) and gas chromatography-mass spectrometry (GC-MS) analyses of the essential oils of leaves and fruits of the ornamental Shinus molle L. were reported and their allelopathic effect on wheat (Triticum aestivum L.) was evaluated. Qualitative and quantitative differences between fruit and leaf oils were observed. Both oils were rich in monoterpene hydrocarbons and the major constituents were limonene and b-phellendrene (35.9-65.4%), a-phellendrene (24.3-20.1%), myrcene (12.8-7.7%) and a-pinene (5.9-1.7%) for fruits and leaves, respectively. Both essential oils showed a dose-dependent allelopathic activity on wheat germination and radicle elongation with leaf oil being the more phytotoxic.

“…However, acorns that dropped beneath mother oaks did not survive well due to the allelopathy (Li et al. 2007) and the Janzen–Connell effect (Janzen 1970; Connell 1971; Liu et al. 2012; Wallraf & Wagner 2019).…”

High rodent abundance increases seed removal but decreases scatter‐hoarding and seedling recruitment along an elevational gradient

The distributions of small rodents in mountainous environments across different elevations can provide important information regarding the effects of climate change on the dispersal of plant species. However, few studies of oak forest ecosystems have compared the elevational patterns of sympatric rodent diversity, seed dispersal, seed bank, and seedling abundance. Thus, we tested the differences in the seed disperser composition and abundance, seed dispersal, seed bank abundance, and seedling recruitment for Quercus wutaishanica along 10 elevation levels in the Taihang Mountains, China. Our results provide strong evidence that complex asymmetric seed dispersal and seedling regeneration exist along an elevational gradient. The abundance of rodents had a significant negative correlation with the elevation and the seed removal rates peaked and then declined with increasing elevation. The seed removal rates were higher at middle and lower elevations than higher elevations but acorns were predated by 5 species of seed predators at middle and lower elevations, and thus, there was a lower likelihood of recruitment compared with those dropped beneath mother oaks at higher elevations. More importantly, the number of individual seeds in the seed bank and seedlings increased with the elevation, although dispersal services were reduced at sites lacking rodents. As conditional mutualists, the rodents could possibly act as antagonistic seed predators rather than mutualistic seed dispersers at low and middle elevations, thereby resulting in the asymmetric pattern of rodent and seedling abundance with increasing elevation to affect the community assembly and ecosystem functions on a large spatial scale.
