Phylogenetic relatedness and competition: a pot experiment with semiarid tree species

open access: yesCERNE, 2022
Background: Factors determining coexistence of the species have been recognized out since Darwin, but empirical studies have brought the relationship between niche similarity and competition into question. Knowing the mechanisms of coexistence makes it possible to predict biological invasions and determine better species combinations for the ...

Filtering across spatial scales: phylogeny, biogeography and community structure in bumble bees. [PDF]

open access: yesPLoS ONE, 2013
Despite the expansion of phylogenetic community analysis to understand community assembly, few studies have used these methods on mobile organisms and it has been suggested the local scales that are typically considered may be too small to represent the ...

Accounting for phylogenetic relatedness in cross-species analyses of telomere shortening rates [PDF]

open access: yes, 2020
Telomeres are repeating DNA sequences found on the ends of chromosomes, which shorten with age and are implicated in senescence. Cross-species analyses of telomere shortening rates (TSR) and telomere lengths are important for understanding mechanisms ...

Plant phylogenetic relatedness and herbivore specialization interact to determine pest biocontrol efficiency in mixed plantations

open access: yesFrontiers in Ecology and Evolution, 2023
Pest herbivory regulation is one of the key functions provided by diverse ecosystems, especially when compared to species depauperate agro-ecosystems and in the context of increased pest outbreaks due to global change.

Community‐level phylogenetic diversity does not differ between rare and common lineages across tallgrass prairies in the northern Great Plains

open access: yesEcology and Evolution, 2022
Niche differentiation has served as one explanation for species coexistence, and phylogenetic relatedness provides a means to approximate how ecologically similar species are to each other.

Phylogenetic relatedness predicts priority effects in nectar yeast communities [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2011
Priority effects, in which the outcome of species interactions depends on the order of their arrival, are a key component of many models of community assembly. Yet, much remains unknown about how priority effects vary in strength among species in a community and what factors explain this variation.

Phylogenetic relatedness rather than aquatic habitat fosters horizontal transfer of transposable elements in animals. [PDF]

open access: yesGenome Res
International audienceHorizontal transfer of transposable elements (HTT) is an important driver of genome evolution, yet the factors conditioning this phenomenon remain poorly characterized. Here, we screened 247 animal genomes from four phyla (annelids,

Barcoding success as a function of phylogenetic relatedness in Viburnum, a clade of woody angiosperms [PDF]

open access: yesBMC Evolutionary Biology, 2012
The chloroplast genes matK and rbcL have been proposed as a "core" DNA barcode for identifying plant species. Published estimates of successful species identification using these loci (70-80%) may be inflated because they may have involved comparisons among distantly related species within target genera.
