From: Contrasting patterns in phylogenetic and biogeographic factories of invasive grasses (Poaceae) across the globe

Test

Hypothesis

Outcomes

Interpretation

(1) Phylogenetic patterns of invasive species

1.1 Phylosignal with PhyloD

Random evolution

D = 1

Purely random emergence

 

Brownian/Neutral evolution

D = 0

Strong neutral clumping

 

Neither Random nor Brownian

1 > D > 1

Moderate relatedness

 

Null

1 = D = 1

Inconclusive

1.2 Diversification rates

Diversification alien promotion

% ~ Div.

Rate of evolution favour invasiveness emergence

 

Null

% × Div.

No relationship

(2) Biogeographical patterns of invasive species

Phylodiversity with SES PD

Generalized regional invasiveness

PD invas = PD all

Ample regional alien diversity produced

 

Restricted lineage invasiveness

PD invas < PD all

Reduced regional alien diversity produced
