“…Therefore, a better understanding of mineral nutrient tree demand, absorption capacity and allocation during reproduction cycles will help design species-specific fertilization treatments, with the ultimate goal of shortening reproduction cycles and increasing gross seed production in the long term. In line with this, previous studies in different species have suggested that N-or P-fertilization enhances tree growth (Turner et al, 2002;Jasim, 2013), improves pollen, ovule viability and seed production (Callahan et al, 2008;Smaill et al, 2011;Ghanem et al, 2014;Bogdziewicz et al, 2017), and reduces the interval of masting events (Bogdziewicz, 2022).…”

Pinus koraiensis is famous for its high-quality timber production all the way and is much more famous for its high value health-care nut oil production potential since 1990’s, but the less understanding of its reproduction biology seriously hindered its nut productivity increase. Exploring the effects of reproduction on nutrient uptake, allocation and storage help to understand and modify reproduction patterns in masting species and high nut yield cultivar selection and breeding. Here, we compared seasonality in growth and in nitrogen ([N]) and phosphorus ([P]) concentrations in needles, branches and cones of reproductive (cone-bearing) and vegetative branches (having no cones) of P. koraiensis during a masting year. The growth of one- and two-year-old reproductive branches was significantly higher than that of vegetative branches. Needle, phloem and xylem [N] and [P] were lower in reproductive branches than in vegetative branches, although the extent and significance of the differences between branch types varied across dates. [N] and [P] in most tissues were high in spring, decreased during summer, and then recovered by the end of the growing season. Overall, [N] and [P] were highest in needles, lowest in the xylem and intermediate in the phloem. More than half of the N (73.5%) and P (51.6%) content in reproductive branches were allocated to cones. There was a positive correlation between cone number and N and P content in needles (R2 = 0.64, R2 = 0.73) and twigs (R2 = 0.65, R2 = 0.62) of two-year-old reproductive branches. High nutrient sink strength of cones and vegetative tissues of reproductive branches suggested that customized fertilization practices can help improve crop yield in Pinus koraiensis.

“…However, during deployment, only a minority of Q. robur trees—both those containing traps and those across each site—appeared to have live catkins that contained fresh pollen. The remaining Q. robur trees contained seemingly moribund catkins, often with stunted growth, possibly as a consequence of an unusually cold and wet May (Met Office, 2021), although pollen production may have also been low in response to a probable mast event the previous year (Bogdziewicz, 2021; Whittle, 2021).…”

1. Woodlands can play an important role in supporting bee abundance and diversity in agricultural landscapes. However, in temperate-region studies, the canopy is rarely sampled, and our understanding of its contribution is limited.2. To explore this, we sampled bees in late spring with blue vane traps in the understory (n = 30) and crowns of mature Quercus robur (n = 35) at the exposed southern edges and in the interiors (ca. 25-75 m from woodland edges) of 15 woodland sites across an English agricultural landscape.3. A significant proportion of bee abundance and diversity was found in the canopy: canopy-trap catches were estimated to be a third as large as understory-trap catches, and 23 of the 29 sampled species were present in the canopy. Of the seven most common species sampled, four were equally abundant in woodland edge and interior traps; three were more abundant in understory traps, and a single species-Bombus lapidarius-was more abundant in canopy traps. The sex ratio of the most abundant species, B. pratorum, was female-skewed in the canopy. Additionally, the presence of nearby Acer pseudoplatanus trees in flower greatly increased canopy-trap catches in woodland interiors.4. These results suggest that both the woodland canopy and understory have a significant role to play in supporting farmland bee communities; they indicate the importance of nectar-producing trees in woodland interiors, opening avenues for canopy-based management; and they demonstrate that a diverse bee community has the potential to exploit canopy floral resources.

“…There is a concern that lowered interannual variability and synchrony of masting might weaken the satiation effect and consequently lower plant recruitment ( 11 , 47 , 51 ) (see refs. 52 , 53 for potential mechanisms of such change). In English populations of European beech ( Fagus sylvatica ), global warming resulted in less synchronized and more even seed production, which in turn increased losses to seed predators ( 47 ).…”

Significance Masting, or synchronous production of large seed crops, is widespread among plants. The predator satiation hypothesis states that masting evolved to overwhelm seed predators with an excess of food. Yet, this popular explanation faced few rigorous tests. We conducted a meta-analysis of studies that related the magnitude of seed production to the intensity of seed predation. Our results validate certain theoretical notions (e.g., that predator satiation is more effective at higher latitudes) but challenge others (e.g., that specialist and generalist consumers differ in the type of functional response to masting). We also found that masting is losing its ability to satiate consumers, probably because global warming affected masting patterns. This shift might considerably impair the reproduction of masting plants.
