“…Results showed no phylogenetic signal in temporal flowering overlap (λ = 0.06-0.48, p > 0.05; Appendix 2, Figure S1) and floral trait similarity (λ = 0.05-0.62, p > 0.05; Appendix 2, Figure S2) indicating that similarity in species' flowering phenology and floral traits are not determined by shared evolutionary history. This is not surprising since in our communities plant families are represented by one or very few species (Angulo et al, 2018). The lack of significant phylogenetic signal in temporal flowering overlap and floral trait similarity suggest that phylogenetic relatedness is likely not a main driver of the structure of these co-flowering communities.…”

“…These communities are located in the east (20°58′37″N–90°21′18″W), centre (21°20′26″N–89°17′47″W) and west (21°33′42″N–87°50′17″W) of the Peninsula. The floras of these three communities have different biogeographic influences (Angulo, Tun‐Garrido, Arceo‐Gómez, Munguía‐Rosas, & Parra‐Tabla, 2018; Moreno‐Casasola & Espejel, 1986) and hence plant species diversity (6–46 species; Parra‐Tabla et al., 2018) and composition are significantly different (PERMANOVA: F 2,47 = 4.28, p < 0.001; C. Albor & V. Parra‐Tabla, unpubl. results).…”

“…Because shared evolutionary history can also play a strong role in shaping patterns of flowering phenology (Rafferty & Nabity, 2017) and floral traits assembly (Ibanez, Arène, & Lavergne, 2016; Shrestha, Dyer, Bhattarai, & Burd, 2014), we tested for phylogenetic signal in the degree of temporal flowering overlap and average floral trait similarity between species within each co‐flowering community. For this, we constructed a phylogeny for plant species in our communities using two plastid genetic markers (matK and rbcL; see Angulo et al., 2018 for details). We estimated phylogenetic signal using Pagels λ (likelihood ratio test with 1,000 randomizations), which scales the covariance matrix of species traits relative to the covariance expected under Brownian evolution (Pagel, 1999).…”

1. Species' floral traits and flowering times are known to be the major drivers of pollinator-mediated plant-plant interactions in diverse co-flowering communities. However, their simultaneous role in mediating plant community assembly and plant-pollinator interactions is still poorly understood. Since not all species flower at the same time, inference of facilitative and competitive interactions based on floral trait distribution patterns should account for fine phenological structure (intensity of flowering overlap) within co-flowering communities. Such an approach may also help reveal the simultaneous action of competitive and facilitative interactions in structuring co-flowering communities. 2. Here we used modularity within a co-flowering network context, as a novel approach to detect convergent and/or over-dispersed patterns in floral trait distribution and pollinator sharing. Specifically, we evaluate differences in floral trait and pollinator distribution patterns within (high temporal flowering overlap) and among co-flowering modules (low temporal flowering overlap). We further evaluate the consistency of observed floral trait and pollinator sharing distribution patterns across space (three geographical regions) and time (dry and rainy seasons). 3. We found that floral trait similarity was significantly higher in plant species within co-flowering modules than in species among them. This suggests pollinator facilitation may lead to floral trait convergence, but only within co-flowering modules. However, our results also revealed seasonal and spatial shifts in the underlying interactions (facilitation or competition) driving co-flowering assembly, suggesting that the prevalent dominant interactions are not static. 4. Synthesis. Overall, we provide strong evidence showing that the use of flowering time and floral trait distribution alone may be insufficient to fully uncover the role of pollinator-mediated interactions in community assembly. Integrating this information along with patterns of pollinator sharing will greatly help reveal the simultaneous action of facilitative and competitive pollinator-mediated interactions in co-flowering communities. The spatial and temporal variation in flowering and trait distribution patterns observed further emphasize the importance of adopting a more dynamic view of community assembly processes.

“…Castillo and Moreno-Casasola 1996; Angulo et al 2018) which, besides the low rainfall and high temperatures, are exposed to other adverse abiotic conditions (e.g., tropical storms, continuous salt spray, and low nutrient availability). The dune plant community is composed of annuals (Cakile edentula -Brassicaceae) and perennial herbs (Sesuvium portulacastrum -Aizoaceae, Licium carollinianum -Solanaceae, Ipomoea pes-caprae -Convolvulaceae), and shrubs such as Scaevola plumieri (Goodeniaceae) and Suriana maritima (Surianaceae) (Espejel 1987;Angulo et al 2018). In this ecosystem, shrubs play an essential role as dune builders and in helping contain soil erosion, which is very relevant for these communities dominated by substrate mobility (Miller et…”

Cassytha filiformis is a hemiparasitic plant that causes severe effects in its host plants. Since this decade, this alien species has been increasing its distribution towards the coastal areas of the Peninsula of Yucatán, parasitizing shrub species that play a crucial role in the containment of soil erosion. Here we studied the current distribution of C. filiformis along the coastal dune in northern Yucatán, recording the frequency of parasitism and the identity of its host plants. In addition, we evaluated the effect of C. filiformis on the sexual reproductive success of the main host plants and the effect of host species identity on C. filiformi’s reproductive success. We found that the distribution of C. filiformis occurs throughout the coastal dunes of Yucatan (covering ≈250km), parasitizing 15 species. However, ca. 70% of C. filiformis plants occur on three common shrub species: Suriana maritima, Scaevola plumieri, and Tournefortia gnaphalodes. The frequency of parasitized plants by C. filiformis was not dependent on host plant abundance. T. gnaphalodes suffer a higher proportion of parasitism. The reproductive success of the three host plants was lower in the presence of the parasitic plant. On the other hand, C. filiformis showed higher reproductive success when parasitizing S. maritima. Our results suggest that C. filiformis has extensively invaded the Yucatán coastal dunes, significantly reducing the sexual reproduction of its host-plant species. Overall, our results suggest that C. filiformis has the potential to cause significant damage in the Yucatán coastal dune community.

“…A diferencia de algunos sistemas del golfo de México, se les considera un sistema de dunas fijas en las que la sedimentación está controlada por la vegetación (Eskuche, 1992;Rust e Illenberg, 1996;Torres et al, 2010). Las comunidades de dunas de esta región presentan una estructura diversa debido a las características hidrológicas, climáticas y edáficas en el litoral (Angulo et al, 2018;Espejel, 1987), lo cual se ve reflejado en los caracteres funcionales de las especies de plantas que les permiten soportar condiciones de alta temperatura, baja disponibilidad de agua y alta exposición a la sal (Martínez et al, 2014, Munguía-Rosas et al, 2019. Espejel (1984) clasificó la vegetación de dunas en 2 tipos, considerando su cercanía al mar.…”
