“…Both species showed different germination percentages according to seed provenance. Germination generally appeared to be higher in seeds from more northerly provenances, probably due to higher northerly seed mass (Carón et al, 2014a), likely caused by a slower seed ripening at lower temperatures, slower seed filling process and therefore a greater total assimilation (Fenner and Thompson, 2005). However, contradicting our hypothesis, seed provenance did not influence seed germination in response to the treatments applied (warming and changes in watering frequency), which indicates that climate change will affect germination of these species similarly in Europe, despite the variable germination rates observed along their distribution range.…”

“…lower survival under warmer conditions). This is likely related to the environmental conditions experienced by the mother tree during seed production (Johnsen et al, 2005a,b;Skrøppa et al, 2010;Carón et al, 2014a). While we lack detailed information on environmental conditions experienced by all the mother trees, previous studies suggest that the observed pattern (different survival according to the seed provenance under changing environmental conditions) is likely related to the temperature experienced during seed production (Johnsen et al, 2005a,b;Carón et al, 2014a,b).…”

“…These locations were selected due the relatively high viability of the seeds produced in these regions in 2011: Italy (40.0 ± 35.3 S.E. % viable seeds per tree), Central Sweden (40.0 ± 12.0) and Norway (55.6 ± 10.7) (Carón et al, 2014a).…”

“…Temperature has been shown to influence seed production (Walck et al, 2011;Carón et al, 2014a), germination, establishment (Lewis et al, 1999;Jensen, 2001) and growth of plants (Rapp et al, 2012). Rainfall amount or soil moisture content may affect plant distributions (North et al, 2005), seed germination (Fay & Schultz, 2009,b;Carón et al, 2014a,b), growth (Fay and Schultz, 2009;Dreesen et al, 2012), phenology (Seghieri et al, 2009), and mortality (Anderegg et al, 2013).…”

“…The technique selected in each case depends on several factors including the life cycle phase that is being investigated. Here, we combine the use of soil heating mats (Carón et al, 2014a) with seed collection along a latitudinal gradient (Fukami and Wardle, 2005;De Frenne et al, 2013). The combination of various techniques constitutes an interesting step further, relative to the use of only one technique because it allows to illuminate the impacts of climate change on different aspects of plant populations such as different phases of plant reproduction (De Frenne et al, 2013).…”

a b s t r a c tClimate projections indicate that temperatures will increase by up to 4.5 • C in Europe by the end of this century, and that more extreme rainfall events and longer intervening dry periods will take place. Climate change will likely affect all phases of the life cycle of plants, but plant reproduction has been suggested to be especially sensitive. Here, using a combination of approaches (soil heaters and different provenances along a latitudinal gradient), we analyzed the regeneration from seeds of Acer platanoides and A. pseudoplatanus, two tree species considered, from a management point of view, of secondary relevance. We studied germination, seedling survival and growth in a full-factorial experiment including warming and changes in watering frequency. Both species responded to warming, watering frequency and seed provenance, with stronger (negative) effects of warming and provenance than of watering frequency. In general, the central provenances performed better than the northernmost and southernmost provenances. We also detected interactive effects between warming, watering frequency and/or seed provenance. Based on these results, both species are expected to show dissimilar responses to the changes in the studied climatic factors, but also the impacts of climate change on the different phases of plant regeneration may differ in direction and magnitude. In general increases in the precipitation, frequency will stimulate germination while warming will reduce survival and growth. Moreover, the frequent divergent responses of seedlings along the latitudinal gradient suggest that climate change will likely have heterogeneous impacts across Europe, with stronger impacts in the northern and southern parts of the species' distribution ranges.

Among plant populations, variation in seed traits has important consequences on species recruitment and performance under different environmental conditions. Knowing such variations and understanding its environmental drivers could help with conservation efforts that protect against the loss of diversity. This information is however lacking in the extinction‐threatened Pterocarpus erinaceus Poir (African rosewood) in Ghana. Here, we assessed variation in seed set, seed morphological and chemical traits, germinability, and seedling growth of African rosewood from four distant provenances (Tumu, Wa, Carpenter, and Ejura) in Ghana. We sought to answer how local environmental conditions influence the expression of seed traits by examining the relationship between seed traits and maternal environmental factors (temperature, rainfall, soil nutrient, and vegetation index) using regression models and correlation analysis. Seed size, mass, and nutrient composition differed considerably among provenances. Seed size and mass increased as the seed source moved further away from the forest‐savanna transition toward the Guineo‐Sudanian savanna regions. Temperature mainly accounted for the variability observed in seed traits. Phenology curves of the seed source vegetation expressed a strong correlation with monthly rainfall. Overall, the occurrence of samara containing whole seeds was low (<50%) except for Tumu provenance. Seeds were rich in carbohydrate and crude protein content consistent with most leguminous plants while mean percentage germination ranged between 30 and 62% among provenances. Our results highlight the adaptive strategies of African rosewood to different environments through the expression of their seed traits and suggest the need for priority action to maintain its conservation.
