Social interactions are ubiquitous in nature and can shape fitness of individuals through social selection. This type of selection arises when phenotypes of neighbors influence the fitness of a focal individual. Quantifying social selection is crucial to better characterise the overall selective landscape. For example, if intraspecific competition is strong, traits that are beneficial for an individual could be detrimental for competitors.

Highbush blueberry [Vaccinium corymbosum L. (Ericales: Ericaceae)] is a major crop in Canada and the United States (Protzman 2021, Agriculture and Agri-Food Canada 2023) and fruit production is enhanced by insect pollination, which increases fruit weight by approximately 75% (Eeraerts et al. 2023).

In this study, 23 ISTR primer pairs were used. A total of 115 bands were obtained from these markers (Fig S1, Tables S3, and Table 6). The P3-F3B3 marker produced the highest number of bands (9 bands). The markers P18-F8B10 and P22-F9B7 exhibited a total of 8 bands apiece, while the markers P2-F2B10 and P19-F9B3 had the lowest count of 2 bands. The average number of bands per marker was 5.00.

Highlights Changes in environmental conditions can lead to variation in the traits expressed by a given genotype within the lifetime of an individual. This phenomenon, referred to as phenotypic plasticity, has been extensively studied in previous decades. The majority of plasticity studies rely solely on reaction norms, which describe the amplitude of changes in traits across gradients of environmental conditions.
