Disparities in the analysis of morphological disparity

T Guillerme, N Cooper, SL Brusatte… - Biology …, 2020 - royalsocietypublishing.org
Analyses of morphological disparity have been used to characterize and investigate the
evolution of variation in the anatomy, function and ecology of organisms since the 1980s. While …

Shifting spaces: Which disparity or dissimilarity measurement best summarize occupancy in multidimensional spaces?

T Guillerme, MN Puttick, AE Marcy… - Ecology and …, 2020 - Wiley Online Library
Multidimensional analysis of traits are now common in ecology and evolution and are
based on trait spaces in which each dimension summarizes the observed trait combination (a …

dispRity: A modular R package for measuring disparity

T Guillerme - Methods in Ecology and Evolution, 2018 - Wiley Online Library
Biological data is multivariate in essence: many traits in organisms covary with each other in
space and time. This causes biologists to either reduce these to a manageable number of …

Ecology and mode-of-life explain lifespan variation in birds and mammals

K Healy, T Guillerme, S Finlay… - … of the Royal …, 2014 - royalsocietypublishing.org
Maximum lifespan in birds and mammals varies strongly with body mass such that large
species tend to live longer than smaller species. However, many species live far longer than …

Concepts and applications in functional diversity

S Mammola, CP Carmona, T Guillerme… - Functional …, 2021 - Wiley Online Library
The use of functional diversity analyses in ecology has grown exponentially over the past
two decades, broadening our understanding of biological diversity and its change across …

SIDER: an R package for predicting trophic discrimination factors of consumers based on their ecology and phylogenetic relatedness

K Healy, T Guillerme, SBA Kelly, R Inger… - …, 2018 - Wiley Online Library
Stable isotope mixing models (SIMMs) are an important tool used to study species' trophic
ecology. These models are dependent on, and sensitive to, the choice of trophic …

[HTML][HTML] Effects of missing data on topological inference using a total evidence approach

T Guillerme, N Cooper - Molecular phylogenetics and evolution, 2016 - Elsevier
To fully understand macroevolutionary patterns and processes, we need to include both
extant and extinct species in our models. This requires phylogenetic trees with both living and …

Endochondral bone in an Early Devonian 'placoderm'from Mongolia

…, E Zorig, R Sansom, T Guillerme… - Nature Ecology & …, 2020 - nature.com
Endochondral bone is the main internal skeletal tissue of nearly all osteichthyans—the group
comprising more than 60,000 living species of bony fishes and tetrapods. Chondrichthyans …

Australian rodents reveal conserved cranial evolutionary allometry across 10 million years of murid evolution

AE Marcy, T Guillerme, E Sherratt… - The American …, 2020 - journals.uchicago.edu
Among vertebrates, placental mammals are particularly variable in the covariance between
cranial shape and body size (allometry), with rodents being a major exception. Australian …

Multiple modes of inference reveal less phylogenetic signal in marsupial basicranial shape compared with the rest of the cranium

…, RMD Beck, T Guillerme… - … of the Royal …, 2023 - royalsocietypublishing.org
Incorporating morphological data into modern phylogenies allows integration of fossil
evidence, facilitating divergence dating and macroevolutionary inferences. Improvements in the …
