Probabilistic modelling improves relative dating from gene phylogenies

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2461-2471, October 2025.
Abstract Establishing the timing of past evolutionary events is a fundamental task in the reconstruction of the history of life. State‐of‐the‐art molecular dating methods generally involve the reconstruction of a species tree from conserved, vertically evolving genes and the assumption of a molecular clock calibrated with the fossil record.

Temporal-spatial distribution of oceanic vertical deflections determined by TOPEX/Poseidon and Jason-1/2 missions

open access: yesEarth Sciences Research Journal, 2016
Deflections of the Vertical (DOV) are essential data in the geodetic observation reduce, the earth gravity field and geoid model refinement, and the mass earth change. The meridional and prime vertical components of global oceanic DOVs are estimated from

Microbial drivers of root plasticity

open access: yesNew Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

It is cool to be clear: Transparency induces a thermal cost in clearwing butterflies

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2452-2464, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In butterflies, wing transparency raises the question of potential costs for vital functions, such as thermoregulation. The thermal melanism hypothesis posits that darker colorations enable higher absorption of solar radiation, leading to the prediction that such ...

Environmental and human factors shape the trophic ecology of a widespread marine predator

open access: yesJournal of Animal Ecology, Volume 94, Issue 9, Page 1784-1799, September 2025.
Our study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.

Spatial and temporal variations of meiofaunal communities from the western sector of the Gulf of Batabanó, Cuba: III. Vertical distribution

open access: yesRevista de Biología Tropical, 2008
The vertical distribution of meiofauna within subtidal sediments was studied in four stations pertaining to mangrove or muddy flats habitats. In 2003, replicated samples were taken in dry (February) and wet (July) seasons at the Bacunagua Inlet ...

Biogeography and biodiversity of gastropod molluscs from the eastern Brazilian continental shelf and slope Biogeografía y biodiversidad de moluscos gastrópodos de la plataforma y talud continental brasileño

open access: yesLatin American Journal of Aquatic Research, 2009
Biogeographic distributional patterns of gastropods are proposed based on the species' geo-graphic and bathymetric distribution. Samples were collected along the Brazilian continental margin between 18° S and 23° S, at 37 stations with depths from 20 m ...
