Phylogenetic Signal and Bias in Paleontology. [PDF]
Syst Biol, 2022 AbstractAn unprecedented amount of evidence now illuminates the phylogeny of living mammals and birds on the Tree of Life. We use this tree to measure the phylogenetic value of data typically used in paleontology (bones and teeth) from six data sets derived from five published studies.

Low interspecific variation and no phylogenetic signal in additive genetic variance in wild bird and mammal populations [PDF]
Ecology and Evolution, 2023 Evolutionary adaptation through genetic change requires genetic variation and is a key mechanism enabling species to persist in changing environments. Although a substantial body of work has focused on understanding how and why additive genetic variance (

Evidence of strong stabilizing effects on the evolution of boreoeutherian (Mammalia) dental proportions [PDF]
Ecology and Evolution, 2019 The dentition is an extremely important organ in mammals with variation in timing and sequence of eruption, crown morphology, and tooth size enabling a range of behavioral, dietary, and functional adaptations across the class.

Measuring phylogenetic signal between categorical traits and phylogenies [PDF]
Bioinformatics, 2018 MOTIVATION Determining whether a trait and phylogeny share some degree of phylogenetic signal is a flagship goal in evolutionary biology. Signatures of phylogenetic signal can assist the resolution of a broad range of evolutionary questions regarding the

Phylogenetic signal in amphibian sensitivity to copper sulfate relative to experimental temperature. [PDF]
Ecological Applications, 2015 The release of large quantities of chemicals into the environment represents a major source of environmental disturbance. In recent years, the focus of ecotoxicology has shifted from describing the effects of chemical contaminants on individual species ...

How to measure and test phylogenetic signal [PDF]
Methods in Ecology and Evolution, 2012 Summary1. Phylogenetic signal is the tendency of related species to resemble each other more than species drawn at random from the same tree. This pattern is of considerable interest in a range of ecological and evolutionary research areas, and various indices have been proposed for quantifying it. Unfortunately, these indices often lead to contrasting

The phylogenetic signal in tooth wear: What does it mean? [PDF]
Ecol Evol, 2018 A new study by Fraser et al (2018) urges the use of phylogenetic comparative methods, whenever possible, in analyses of mammalian tooth wear. We are concerned about this for two reasons.

Phylogenetic signal in flowering phenology weakens over elevation in the high Andes of Chile: evidence for evolutionary convergence in a harsh habitat [PDF]
Frontiers in Plant ScienceIntroductionHigh elevation plants experience cold temperatures and short growing seasons that constrain their flowering window. These environmental limitations are expected to promote strong overlap in flowering phenology among co-occurring species ...

Spatial scale-dependent phylogenetic signal in species distributions along geographic and elevation gradients in a mountainous rangeland. [PDF]
Ecol Evol, 2018 The mechanisms determining community phylogenetic structure range from local ecological mechanisms to broad biogeographical processes. How these community assembly processes determine phylogenetic structure and patterns in rangeland communities across ...
