Do richness and rarity hotspots really matter for orchid conservation in light of anticipated habitat loss?

Abstract: AimThe aim of this analysis was to identify strategies that will maximize efficiency and effectiveness in conservation planning. As many orchids are threatened with extinction for various reasons, our primary objective was to combine hotspots analyses with stochastic extinction modelling to highlight possible conservation priorities for Lepanthes spp. (Orchidaceae) based on patterns of richness, rarity and threat. Our subsequent objective was to identify potential conservation surrogates and variables that are… Show more

“…First, preserving ecosystem functions (Harvey, Gounand, Ward, & Altermatt, ) requires additional understanding what role in ecosystems play rare and common species, as well understanding interactions between different taxa (e.g., beetles from families Leiodidae vs. Carabidae) and ecological groups (e.g., aquatic vs. terrestrial). Second, an optimal conservation strategy should incorporate all available information into an analytic framework that will, in addition to species richness consider alternative metrics of biodiversity, such as rarity, weighted endemism, β diversity, and their relation to threat (Crain & Tremblay, ; Myers, Mittermeier, Mittermeier, da Fonseca, & Kent, ; Yu et al, ; Zhao, Li, Liu, & Qin, ). This analytic framework based on multiple criteria would possible consider common species, and not only rare species, in conservation planning of subterranean habitats.…”

“…Acer rubrum was not a primary nearest neighbor, but was a species of interest (i.e., part of the "Quercus-to-Acer" transition) therefore it was also analyzed to determine its spatial dependence. Getis-Ord Gi* was used to find the extent to which each feature was surrounded by similar high or low values to determine patterns of distribution (i.e., clusters; [79]. All spatial data were examined at three resolutions: 5ˆ5 m, 10ˆ10 m, and 20ˆ20 m, to observe how patterns changed across spatial scale.…”
