Congeneric predators fill discrete niches created by the relative abundances of their prey species

open access: yesJournal of Avian Biology, 2022
To what degree is niche partitioning driven by underlying patterns in resources such as food, rather than by competition itself? Do discrete niches exist?

Connecting the distribution and diversification of marine plants

open access: yesOikos, Volume 2026, Issue 7, July 2026.
Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...

Trapped in the web: network architectures spread coevolution and shape adaptation

open access: yesOikos, Volume 2026, Issue 7, July 2026.
Adaptation is critical for biodiversity to persist under global change. Within ecological communities, species often face tradeoffs between adapting to shifting abiotic conditions and navigating the complex selective pressures imposed by interaction networks.

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1116-1131, July 2026.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Macroevolution is more than repeated rounds of microevolution

open access: yes, 2020
SUMMARY Arguments over macroevolution versus microevolution have waxed and waned through most of the twentieth century. Initially, paleontologists and other evolutionary biologists advanced a variety of non-Darwinian evolutionary processes as ...

Estimating clade‐specific diversification rates and palaeodiversity dynamics from reconstructed phylogenies

open access: yesMethods in Ecology and Evolution, 2023
Understanding palaeodiversity dynamics through time and space is a central goal of macroevolution. Estimating palaeodiversity dynamics has been historically addressed with fossil data because it directly reflects the past variations of biodiversity ...

Leaf Size in Conifers: Global Associations With Climate and Evolutionary History

open access: yesGlobal Change Biology, Volume 32, Issue 7, July 2026.
Global patterns in leaf size are linked to climatic trade‐offs, so we explore these relationships in a major group of plants, the conifers. Using contemporary phylogenetic methods, we show that conifers display a strong pattern of evolutionary conservatism in the association of leaf size with climate, and highlight that these relationships are driven ...

Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Macroevolution and macroecology through deep time

open access: yes
The fossil record documents two mutually exclusive macroevolutionary modes separated by the transitional Ediacaran Period. Despite the early appearance of crown eukaryotes and an at least partially oxygenated atmosphere, the pre-Ediacaran biosphere was ...
