Synthesis of Population Trends Reveals Seascape‐Wide Reorganisation of Biodiversity From Microalgae to Birds

open access: yesGlobal Change Biology, Volume 31, Issue 6, June 2025.
We present a systematic and quantitative analysis of population trends to capture the seascape‐wide reorganisation of biodiversity from microalgae to birds. First, we categorised population trends and found over one third of populations in the Wadden Sea to change, that is, increase or decrease.

What Are the Phylogenetic Limits to Pollinator Diversity?

open access: yesJournal of Applied Entomology, Volume 149, Issue 5, Page 697-703, June 2025.
ABSTRACT Although huge progress has been made over the past 200 years in identifying the diversity of pollinators of angiosperms and other plants, new discoveries continue to be made each year, especially in tropical areas and in the fossil record. In this perspective article I address the following questions: Just how diverse are the pollinators and ...

Neural canal ridges: A novel osteological correlate of postcranial neuroanatomy in dinosaurs

open access: yesThe Anatomical Record, Volume 308, Issue 5, Page 1349-1368, May 2025.
Abstract In this article, we document the widespread presence of bony ridges in the neural canals of non‐avian dinosaurs, including a wide diversity of sauropods, two theropods, a thyreophoran, and a hadrosaur. These structures are present only in the caudal vertebrae.

Possible identification of CENP-C in fish and the presence of the CENP-C motif in M18BP1 of vertebrates. [version 2; referees: 2 approved]

open access: yesF1000Research, 2016
The centromeric protein CENP-C is a base component of the kinetochore. This protein, along with CENP-A has been shown to adaptively evolve in a number of animal and plant species.
