Phylogenetic diversity in the Iberian flora through the Cenozoic

open access: yes, 2020
Phylogenetic diversity reflects both community assembly and evolutionary diversification processes. Communities with low phylogenetic diversity might be the outcome of environmental filters favouring the occurrence and/or the diversification of lineages ...

Environmental and host plant effects on taxonomic and phylogenetic diversity of root fungal endophytes. [PDF]

open access: yesFEMS Microbiol Lett
Nearly all plants are colonized by fungal endophytes, and a growing body of work shows that both environment and host species shape plant-associated fungal communities.

Contrasting taxonomic and phylogenetic diversity responses to forest modifications: comparisons of taxa and successive plant life stages in South African scarp forest.

open access: yesPLoS ONE, 2015

Multifaceted fish diversities respond differently to impounding age and longitudinal location along a reservoir cascade

open access: yesFrontiers in Ecology and Evolution, 2022
Damming usually modifies riverine habitats, which affects various aspects of fish diversity, especially in a reservoir cascade. Their influence on fish assemblage has been studied widely, but a lack of data from the diversity perspective remains.
