“…Th is is further supported by its low mortality at high salinity levels and its ability to reproduce under saline conditions. While high salinity levels at the end of the tolerance range of B. halimifolia are likely to delay or reduce the probability of fl owering, moderate salinity levels triggered fl owering, both in the greenhouse (present study) and in the fi eld ( Caño et al, 2013b ). Earlier fl owering under moderate salinity stress, which has also been reported in other species ( Castro et al, 2013 ), has been proposed as an adaptive stress-avoidance mechanism ( Stanton et al, 2000 ;Friesen et al, 2014 ).…”

“…We observed diff erential eff ects of parental Na + on off spring biomass and fl oral initiation in male and female cuttings. If vegetative growth of B. halimifolia is not sustained during fl owering ( Caño et al, 2013b ), then diff erent phenological stages between sexes at harvest time could explain, in part, why parental eff ects were evident in a reproductive trait for males and in a vegetative trait for females. However, we cannot exclude other mechanisms that may have caused sex-dependent parental eff ects, a topic that has scarcely been investigated in plants and that is beyond the scope of this study.…”

“…We transplanted a total of 280 seedlings and assigned 56 plants (seven plants per maternal line) to each of the fi ve levels of salinity: 0 (control), 5, 10, 15, and 20 g NaCl L −1 . Th ese salinity levels allowed us to create a continuous salinity gradient corresponding to the salinity conditions experienced by B. halimifolia in the sampled site ( Caño et al, 2013b ;. Salinity levels were created by watering twice per week with a deionized water solution containing corresponding concentrations of NaCl (0, 5, 10, 15, and 20 g NaCl L −1 ), and once a week with full-strength Hoagland nutrient solution containing the same NaCl concentration.…”

“…The American genus Baccharis (Asteraceae) is also present on the island with three species, of which the endemism Baccharis haistiensis Heering & Urban grows in semiarid environments of the dry forest (Liogier 1996. However, this genus also presents the species B. halimifolia L., which is invasive on the Atlantic coasts of Western Europe (Cañ o et al 2013).…”

We conduct a study of the dry forest in areas of scant rainfall in the Dominican Republic; these are sites with particular endemic habitats, as the samples reveal a high rate of local and insular endemic species, with 84 (24.85%) endemisms. This work covers dry forests rich in coarse spiny plants and includes a statistical (multivariate analysis), phytosociological and catenal study of the vegetation. We analyse the floristic composition, ecology, distribution and richness in endemisms of each association. The bioclimatic analysis reveals the different thermotypes and ombrotypes on the island, and locates the proposed plant associations in the infra-and thermotropical thermotypes, and in the arid, semiarid and dry ombrotypes. As a result of this phytosociological analysis, we propose the new alliance Harrio nashii -Acacion skleroxylae and four plant associations: Harrisio nashii -Prosopidetum juliflorae, Crotono poitaei -Erythroxyletum rotundifolii, Lonchocarpo pycnophylliCylindropuntietum caribaeae and Neoabbottio paniculatae -Guaiacetum officinali; these associations connect catenally with the subhumid forest and mangrove swamps.

Female Salix viminalis are more severely infected by Melampsora spp. but neither sex experiences associational effects

Associational effects of plant genotype or species on plant biotic interactions are common, not least for disease spread, but associational effects of plant sex on interactions have largely been ignored. Sex in dioecious plants can affect biotic interactions with herbivores and pollinators; however, its effects on plant–pathogen interactions are understudied and associational effects are unknown. In a replicated field experiment, we assessed Melampsora spp. leaf rust infection in monosexual and mixed sex plots of dioecious Salix viminalis L. to determine whether plant sex has either direct or associational effects on infection severity. We found no differences in Melampsora spp. infection severity among sexual monocultures and mixtures in our field experiment. However, female plants were overall more severely infected. In addition, we surveyed previous studies of infection in S. viminalis clones and reevaluated the studies after we assigned sex to the clones. We found that females were generally more severely infected, as in our field study. Similarly, in a survey of studies on sex‐biased infection in dioecious plants, we found more female‐biased infections in plant–pathogen pairs. We conclude that there was no evidence for associational plant sex effects of neighboring conspecifics for either females or males on infection severity. Instead, plant sex effects on infection act at an individual plant level. Our findings also suggest that female plants may in general be more severely affected by fungal pathogens than males.
