WebThe SDMs have arisen out of decades of ecological inquiry and analyses related to species-environment relationships (e.g., 5) and share a common philosophy and theoretical foundation with indirect gradient analysis, in that they attempt to relate observed spatial variations in species frequency to associated underlying environmental gradients. WebJun 13, 2024 · The gradient of decreasing inundation duration away from a river often corresponds to increasing stem specific gravity, seed mass, plant height, longevity, ability to spread via rhizomes or stolons, total cover and biomass and a decrease in species richness (Friedman et al., 1996; Kyle & Leishman, 2009; McCoy-Sulentic et al., 2024 ).

WebThe mechanisms of how vegetation dynamics responds to climate are not yet resolved (Piao et al. 2006). Natural gradient analysis is a useful tool for studying the different responses of vegetation dynamics to cli-matic variables in diverse areas with different water and energy conditions (Epstein et al. 1996,Liet al. 2015,Yealet . 2015).
