Functional types in the Bromeliaceae: relationships with drought‐resistance traits and bioclimatic distributions

Abstract: Summary1. Neotropical Bromeliaceae occupy an exceptional diversity of habitats. The five principal functional types, which are defined by innovations such as Crassulacean acid metabolism (CAM), epiphytism, the tank growth form and neoteny, display distinct ecological water-use strategies. 2. The contribution of putative drought-resistance traits to the ecological differentiation of functional types has not previously been assessed, despite growing interest in the importance of these traits in other plant group… Show more

“…Our hypothesis of differences among epiphyte taxonomic groups was only partially supported by bromeliads, while ferns and orchids followed similar trait–trait relationships (Figure 3). Atmospheric CAM and tank C 3 bromeliads clustered separately in most analyses, suggesting distinct differences between bromeliad types (Males & Griffiths, 2017). Surprisingly, it was the C 3 bromeliads that showed the least similarity to the trait patterns in orchids and ferns, but a broader survey of CAM and C 3 bromeliads across the traits examined here would be necessary to draw further conclusions.…”

“…Codes for variables: AET/ PET, actual evapotranspiration/potential evapotranspiration; MAP, mean annual precipitation; P dry , precipitation in driest month; P seas , precipitation seasonality. Am, Amazonian domain; Ch, Chaquenian domain; SDTF, Seasonally Dry Tropical Forest domain drought-resistant than most CAM tank-epiphytes and showed significantly more negative osmotic potential at full turgor (π o ), as well as higher saturated water content (SWC), water mass per unit area (WMA), and dry leaf mass per unit area (LMA) than the CAM tankepiphytes (Males & Griffiths, 2017). However, A. distichantha ranked among the CAM tank-epiphytes with higher LMA, WMA and SWC (see Figure S1 in Appendix S4) denoting a high drought resistance (Males & Griffiths, 2017).…”

“…Plants under drought conditions will reduce leaf area and increase leaf thickness (Rowland et al, 2020). Drought stress also alters plant physiological processes, among which amendments to pigment composition and subsequent photosynthesis are the most critical (Males and Griffiths, 2017). A reduction in chlorophyll affected by moisture content has been reported (He and Dijkstra, 2014).…”
