Neighbours and relatives: accounting for spatial distribution when testing causal hypotheses in cultural evolution

open access: yesEvolutionary Human Sciences, 2023
Many important and interesting hypotheses about cultural evolution are evaluated using cross-cultural correlations: if knowing one particular feature of a culture (e.g.

Phylogenetic diversity in conservation: A brief history, critical overview, and challenges to progress

open access: yesCambridge Prisms: Extinction, 2023
Species that are evolutionarily distinct have long been valued for their unique and irreplaceable contribution to biodiversity. About 30 years ago, this idea was extended to the concept of phylogenetic diversity (PD): a quantitative, continuous-scale ...

Language endangerment: Using analytical methods from conservation biology to illuminate loss of linguistic diversity

open access: yesCambridge Prisms: Extinction, 2023
Language diversity is under threat, with between a third to a half of all languages considered endangered, and predicted rates of loss equivalent to one language per month for the rest of the century.

Data on pteridophyte species diversity and status of the International Union for Conservation of Nature in each political unit of Myanmar

open access: yesData in Brief, 2020
The data in this article provide information about the species richness of each political unit in Myanmar and their preliminary conservation status. The dataset was compiled by gathering scattered data from different sources.

Speciational view of macroevolution: Are micro and macroevolution decoupled? [PDF]

open access: yesEurophysics Letters (EPL), 2006
We introduce a simple computational model that, with a microscopic dynamics driven by natural selection and mutation alone, allows the description of true speciation events. A statistical analysis of the so generated evolutionary tree captures realistic features showing power laws for frequency distributions in time and size.

First assessment of pteridophytes’ composition and conservation status in Myanmar

open access: yesGlobal Ecology and Conservation, 2020
The ongoing biodiversity crisis enforces the need of practical conservation plans based on robust estimates of the threats to local from regional biodiversity.

Ecomorphological diversification of squamates in the Cretaceous [PDF]

open access: yesRoyal Society Open Science, 2021
Squamates (lizards and snakes) are highly successful modern vertebrates, with over 10 000 species. Squamates have a long history, dating back to at least 240 million years ago (Ma), and showing increasing species richness in the Late Cretaceous (84 Ma ...

Morphological disparity of early ammonoids: A geometric morphometric approach to investigate conch geometry

open access: yesActa Palaeontologica Polonica, 2023
Fossils of Devonian ammonoids are abundant and well-preserved in the Anti-Atlas of Morocco; as such they provide an invaluable record of regional morphological disparity changes (diversity of shapes) that characterise the first steps of ammonoid ...

Memory in trait macroevolution [PDF]

open access: yesThe American Naturalist, 2018
Abstract The history of a trait within a lineage may influence its future evolutionary trajectory, but macroevolutionary theory of this process is not well developed. For example, consider the simple binary trait of living in cave versus surface habitat.

Has frugivory influenced the macroecology and diversification of a tropical keystone plant family? [PDF]

open access: yesResearch Ideas and Outcomes, 2017
Seed dispersal by fruit-eating animals is a pivotal ecosystem function in tropical forests, but the role that frugivores have played in the biogeography and macroevolution of species-rich tropical plant families remains largely unexplored.
