a negative trendp = 2 × 10 −5
Based on the observed data, a negative trend of four species lost per census (per 5 years) was observed ( figure 4 d ; average p = 2 × 10 −5 from bootstrap least-squares linear regression).
Based on the observed data, a negative trend of four species lost per census (per 5 years) was observed ( figure 4 d ; average p = 2 × 10 −5 from bootstrap least-squares linear regression).
The observed richness across years indicated a weak signal of temporal increase but was inconclusive ( p = 0.17), while Ω indicated slightly more support for a positive trend ( p = 0.13 ; figure 4 i,j ).
