WebApr 8, 2024 · In ecology, niche theory has guided the development of species distribution models (SDMs) [137] to extend the potential distribution of organisms beyond occurrences based on habitat suitability. Broadly, there are two groups of SDMs, correlative and mechanistic [138] . WebMay 27, 2024 · Species distribution models (SDMs) ( 41) concern the modeling of the landscape-explicit probability of presence of a species based on the realized niche. This occurs by relying primarily on the habitat suitability ( 42) given its biotic and abiotic factors.
