“…Elevated CO 2 , through decreasing stomatal conductance, increases water use efficiency [15]. In water stress conditions, this may allow plants to retain more seeds, but yields will always be lower compared to those in non-resource stress environments [15]. Sometimes there is also an increase in seed mass [21], although the effects of elevated CO 2 on seed mass are highly variable [22].…”

“…Yield increases are usually because of a greater number of seeds per unit area [17][18][19] as a result of increased resource use efficiency for radiation, water, and nitrogen [20]. Elevated CO 2 , through decreasing stomatal conductance, increases water use efficiency [15]. In water stress conditions, this may allow plants to retain more seeds, but yields will always be lower compared to those in non-resource stress environments [15].…”

“…Most arable crop species are vulnerable to heat stress both pre-and post-fertilization, and any exposure to temperatures above the optimum for the species can result in significant seed yield losses [24][25][26] with the extent of the reduction in individual seed yield components depending on the timing and duration of the temperature stress experienced. Temperature increases, which reduce seed number, accelerate seed growth rate, reduce the duration of seed filling, and sometimes reduce seed mass [15] can, therefore, negate any positive seed yield responses to increased CO 2 .…”

“…The impacts of changing climate and climate variability on seed production of arable crops such as rice, soybean, cotton, and peanut has been recently reviewed [15]. Enrichment of atmospheric CO 2 is likely to increase seed yields of C3 arable crops (e.g., wheat) by between 11% and 30% but leave yields of C4 crops (e.g., maize) unchanged [11,16].…”

“…Seed is the basic and most vital input of agriculture [14], and the seed industry must be able to continue to deliver the quantities of quality seed required for this purpose. Climate change poses several challenges for the continued production of high quality seed [15]. In this review, we examine the effects of climate change on seed production and explore options for adaptation of seed production in response to climate change, with a focus on the effects of increased CO 2 , increased temperature, and their interaction.…”

Food security depends on seed security and the international seed industry must be able to continue to deliver the quantities of quality seed required for this purpose. Abiotic stress resulting from climate change, particularly elevated temperature and water stress, will reduce seed yield and quality. Options for the seed industry to adapt to climate change include moving sites for seed production, changing sowing date, and the development of cultivars with traits which allow them to adapt to climate change conditions. However, the ability of seed growers to make these changes is directly linked to the seed system. In the formal seed system operating in developed countries, implementation will be reasonably straight forward. In the informal system operating in developing countries, the current seed production challenges including supply failing to meet demand and poor seed quality will increase with changing climates.

Climate warming increases insect‐driven seed removal of two elaiosome‐bearing invasive thistle species

Ants and other insects are often a source of localized secondary dispersal for wind‐dispersed plants and thus play an important ecological role in their spatial dynamics, but there is limited information on how climate change will affect such dispersal processes. Here, we use field experiments to investigate how climate warming affects seed removal, as this initiation of movement represents the first step in insect‐driven secondary dispersal. Our results indicate that for the invasive thistles Carduus nutans and Carduus acanthoides, increased growing temperature influences seed attractiveness to insect dispersers, with seeds from maternal plants grown at temperatures 0.6°C above ambient removed by insect dispersers at higher rates than their unwarmed counterparts. We also observe that seed elaiosomes in these two species play an important role in dispersal, as seeds without elaiosomes were significantly less likely to be removed over the same period. Significant interactions between elaiosome presence/absence and warming treatment were also observed, though only for C. acanthoides, with the boost in seed removal from warming dampened when the elaiosome was present compared to when it was absent. These findings provide evidence that climate warming may alter aspects of dispersal such as seed removal by secondary dispersers, with potential ramifications for dispersal in future climates since seed‐bearing plants around the world may be subject to increased growing temperatures, and many of these plant species bear elaiosomes and experience seed dispersal by insects.
