Uchanganuzi wa Thamani ya Viashirio

Uchanganuzi wa Thamani ya Kiashirio (IndVal), uliotengenezwa na Dufrene na Legendre (1997), unataja spishi ambazo huashiria kwa uaminifu kuwepo kwa hali mahususi za kimazingira, aina za makazi, au vikundi vya jamii. Njia hii inapima uhusiano kati ya spishi na makazi, ikitoa thamani ya kiashirio inayochanganya uthabiti (upendeleo wa kipekee kwa makazi fulani) na uaminifu (uwepo thabiti wakati makazi yanapotokea). IndVal hutumiwa sana katika uhifadhi kutambua spishi za wasiwasi wa usimamizi, katika kuainisha makazi kugundua spishi viashirio, na katika ekolojia ya marejesho kutathmini kama jamii zilizorejeshwa zinahusiana na hali za marejeleo.
