“…It has been repeatedly demonstrated that aboveground biomass is positively correlated with flowering intensity and seed production (e.g., [ 43 – 48 ]). In addition, the studied species not only reproduce generatively but also show extensive vegetative reproduction [ 23 ], and the intensity of clonal reproduction is also a function of plant size ([ 49 ], [ 50 ]). Plant aboveground biomass is thus expected to be a suitable proxy for plant fitness in these species.…”

Due to increased levels of heterozygosity, polyploids are expected to have a greater ability to adapt to different environments than their diploid ancestors. While this theoretical pattern has been suggested repeatedly, studies comparing adaptability to changing conditions in diploids and polyploids are rare. The aim of the study was to determine the importance of environmental conditions of origin as well as target conditions on performance of two Anthericum species, allotetraploid A. liliago and diploid A. ramosum and to explore whether the two species differ in the ability to adapt to these environmental conditions. Specifically, we performed a common garden experiment using soil from 6 localities within the species’ natural range, and we simulated the forest and open environments in which they might occur. We compared the performance of diploid A. ramosum and allotetraploid A. liliago originating from different locations in the different soils. The performance of the two species was not affected by simulated shading but differed strongly between the different target soils. Growth of the tetraploids was not affected by the origin of the plants. In contrast, diploids from the most nutrient poor soil performed best in the richest soil, indicating that diploids from deprived environments have an increased ability to acquire nutrients when available. They are thus able to profit from transfer to novel nutrient rich environments. Therefore, the results of the study did not support the general expectation that the polyploids should have a greater ability than the diploids to adapt to a wide range of conditions. In contrast, the results are in line with the observation that diploids occupy a wider range of environments than the allotetraploids in our system.

“…5). Numerous studies have shown that reduction of soil nutrients will significantly increase the allocation of root biomass to capture more resources (Watson 1984, Jónsdóttir and Watson 1997, Wang et al 2009, Song et al 2013, D'Hertefeldt et al 2014. In our experiment, the amount of N remained constant but P decreased gradually.…”

“…We did not find high costs of maintaining stolon connection in CS 7:1 compared to high N/P availability, indicating that low N/P ratio easily compensate for resource investment into the stolon connection of Z. japonica in homogeneous environments. This is the consequence of high resource availability by providing copious resources for plant growth and reproduction, and thus the costs of plants on a certain trait (physiological integration) can be considerably aggravated by high N/P nutrient supply (D'Hertefeldt andJónsdóttir 1999, D'Hertefeldt andFalkengren-Grerup 2002). With respect to the different main parts of Z. japonica, the present study provide evidence regarding plant response and tolerance to clipping.…”

“…The balance between costs and benefits of clonal integration may be altered by stolon severing and nutrient supply in natural habitats. How the phenotypic response under different external stress and clonal integration influence the performance of clonal plants in natural ecosystems is more complicated both locally and regionally (D'Hertefeldt et al 2014) than results from pot experiments may suggest. The interactions between resource heterogeneity and herbivory-induced stress should be studied under field conditions to better understand the relationship between nutrient supply and defoliation or severing stress.…”

“…The degree of clonal integration varies among different clonal species, and the cut-off point might occur when the whole clone experiences extreme stress. Since clonal integration has both advantages and disadvantages to clonal plants (Limpens et al 2004, Gundale et al 2011, Granath et al 2012, D'Hertefeldt et al 2014, it is necessary to experimentally investigate the growth costs and benefits of clonal integration of a clonal plant species under various experimental conditions.…”

Clonal plants adaptively respond to abiotic stress, but to date little is known about under what circumstanses clonal integration is beneficial, or costly. To study the costs and benefits of clonal integration on clonal growth, we cultivated Zoysia japonica under three ratios of N:P (N:P ≈ 7, 14:1 and 21:1), and four types of stolon severing treatments (connected stolon CS, light severing LS, moderate severing MS, serious severing SS). The results showed that Z. japonica performed best at a low ratio of N:P (N:P ≈ 7:1). When the stolons were connected (CS), the growth of primary A‐ramets, multiple‐nodes and stolons benefited from clonal integration; however, the growth of primary B‐ramets on the primary stolons, A and B ramets was significantly reduced (p < 0.05). In the moderate stolon severing treatment MS7:1 (N:P ≈ 7:1), clonal integration appeared more cost effective than in all other treatments. On the whole, with increasing stolon severing intensity, the cost of clonal integration increased and the clonal growth of Z. japonica declined significantly. The pattern of biomass allocation may be useful for Z. japonica to adapt to the various environments, and clonal integration plays a significant role under adverse environmental conditions.

Plant provenance can influence the impacts of temperature and moisture on intraspecific competition in Pseudoroegneria spicata

Warming and changing precipitation can alter the performance of native grasses that are essential to grassland ecosystems. Native grasses may respond to changing climate by phenotypic plasticity or lose their current ranges. Establishing plant species from southern, warmer provenances may reduce the likelihood of biodiversity loss and improve restoration success in cool, northern locations that are undergoing warming. We conducted competition trials for Pseudoroegneria spicata (bluebunch wheatgrass), a native grass commonly found in western North American grasslands, to understand the impact of temperature and moisture on plant–plant interactions. We obtained seeds from three locations along a latitudinal gradient in North America, two in British Columbia (BC), Canada, and one in California, USA. We compared the effects of warming, changing water inputs, and competitor provenance on pairwise competitive interactions among Pseudoroegneria spicata plants grown from seeds obtained from the three locations. We quantified interactions using the relative interaction intensity, which has values from −1 (complete competition) to +1 (complete facilitation). Target plants from northern British Columbia, the location with the coldest summer temperature, were generally more competitively suppressed when competing with plants from California, which had the warmest summer temperature and lowest summer precipitation. Competitive suppression of target plants from northern British Columbia and southern British Columbia was more intense when competitor provenance was more geographically distant from target plant provenance. Finally, plants from northern British Columbia and southern British Columbia were more suppressed at higher temperatures, indicating some local adaptation, while plants from California were not affected by competitors, temperature, or water input. Plants grown from seeds obtained from warm and dry locations appear to be more tolerant to competition at higher temperatures, compared to plants from cooler regions. Native plant diversity and restoration success in grasslands subjected to climate change may be preserved or improved by assisted migration of seeds from warm to cooler but warming locations.
