Trait coevolution and causal inference using generalized dynamic phylogenetic models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Phylogenetic comparative methods are widely used to study trait coevolution across biological and cultural domains. The most common methods are phylogenetic generalized linear (mixed) models, phylogenetic path analysis, Pagel's ‘discrete’ method and Ornstein–Uhlenbeck models. While some frameworks like generalized linear mixed models are quite

Regulating Uncharted Waters: The EU Platform Work Directive Between Uncertainty, Lobbyism and Politicisation

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract In 2024, the EU adopted a much‐debated directive on improving working conditions in platform work, which aims to facilitate the correct classification of people performing platform work and regulates the use of algorithmic management. The initiative attracted intense lobbying from digital platforms and trade unions, whilst dividing the member ...

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

open access: yesJournal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

Anthropocene bodies, geological time and the crisis of natality [PDF]

open access: yes, 2017
In its explicit engagement with the possibility of human extinction, the Anthropocene thesis might be seen as signalling a `crisis of natality’. Engaging with two works of fiction - Cormac McCarthy’s The Road (2006) and Anne Michaels’ Fugitive Pieces ...

Novel Glomeromycotina–moss associations identified in California dryland biocrusts

open access: yesNew Phytologist, EarlyView.
Summary Drylands, which comprise c. 45% of Earth's land area, host biological soil crusts (biocrusts): symbiotic communities of cyanobacteria, fungi, algae, lichen, and bryophytes that stabilize soil and support key ecosystem functions. Moss‐dominated biocrusts are particularly interesting due to their potential to illuminate ancient bryophyte–fungal ...

Mid‐infrared spectroscopy applied to a multi‐level cave system (Montmaurin, SW France): An innovative method for assessing sediment provenance

open access: yesSedimentology, EarlyView.
ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

Involvement of microbial mats in early fossilization by decay delay and formation of impressions and replicas of vertebrates and invertebrates

open access: yesScientific Reports, 2016
Microbial mats have been hypothesized to improve the persistence and the preservation of organic remains during fossilization processes. We test this hypothesis with long-term experiments (up to 5.5 years) using invertebrate and vertebrate corpses.

Intraspecific variation of cochlear morphology in bowhead and beluga whales

open access: yesThe Anatomical Record, Volume 309, Issue 6, Page 1514-1529, June 2026.
Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Marsupial Lions & Methodological Omnivory: Function, Success and Reconstruction in Paleobiology [PDF]

open access: yes, 2015
Historical scientists frequently face incomplete data, and lack direct experimental access to their targets. This has led some philosophers and scientists to be pessimistic about the epistemic potential of the historical sciences.
