Hybridization plays a significant role in biological evolution. However, it is not clear whether ecological contingency differentially influences likelihood of hybridization, particularly at ecological margins where parental species may exhibit reduced fitnesses. Moreover, it is unknown whether future ecosystem change will increase the prevalence of hybridization. Ficus heterostyla and F. squamosa are closely related species co-distributed from southern Thailand to southwest China where hybridization, yielding viable seeds, has been documented. As a robust test of ecological factors driving hybridization, we investigated spatial hybridization signatures based on nuclear microsatellites from extensive population sampling across a widespread contact range. Both species showed high population differentiation and strong patterns of isolation by distance. Admixture estimates exposed asymmetric interspecific gene *** of hybridization increase significantly towards higher latitude zones, peaking at the northern climatic margins. Geographic variation in reproductive phenology combined with ecologically challenging marginal habitats may promote this phenomenon. Our work is a first systematic evaluation of such patterns in a comprehensive, latitudinally-based clinal context, and indicates that tendency to hybridize appears strongly influenced by environmental conditions. Moreover, that future climate change scenarios will likely alter and possibly augment cases of hybridization at ecosystem scales.

To the Editor:Probiotics are a promising treatment modality for functional constipation(FC);however,the factors affecting individual responses to probiotics remain *** evidence has identified that there is a strong relationship among the gut microbiota and constipation and related gut-brain axis.[1]The gut microbiota may modulate the gut functions via gut metabolites or trigger the release of gut hormones,such as peptide YY,gastric inhibitory polypeptide,and 5-hydroxytryptamine.[2]In turn,gut hormones affect gut secretion,motility,and sensation through their receptors located on epithelial,enteric,and smooth muscle cells.[2]Based on these findings,exogenous probiotics have been used in patients with constipation;however,few have produced consistent results.[3]In this study,we investigated the efficacy and safety of several specific probiotics strains for constipation,and also examined the potential reasons for the individualized effects of probiotics,which may facilitate interventional decisionmaking for FC patients.
