Fusion or Confusion? Assessing the Impact of Visible‐Thermal Image Fusion for Automated Wildlife Detection

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study evaluates the performances of synchronous aerial visible (VIS) and thermal infrared (TIR) imagery for detecting great blue heron (Ardea herodias) nests and individuals using a YOLO11n model. VIS and TIR images were automatically aligned using deep learning, and both early and late fusion approaches were tested.

High thermal plasticity, low heritability and constant directional selection on breeding phenology in a viviparous ectotherm

open access: yesJournal of Animal Ecology, EarlyView.
Our findings reveal that breeding phenology of the common lizard is shaped by strong thermal plasticity, body size effects, constant selection for earlier parturition, but low heritability. This suggests that phenological responses to climate change in this species, and likely in other squamates, will predominantly arise through plastic rather than ...

Contrasting associations between parental coordination and breeding success in albatrosses across differing environmental contexts

open access: yesJournal of Animal Ecology, EarlyView.
Our study demonstrates that the benefits of parental coordination in albatrosses are context‐dependent rather than universal. Coordinated parental care enhanced reproductive success in stable environments, but had little effect in variable environments, where individual flexibility may be more valuable.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

The emergence and complexification of symbolic practices in the Homo lineage: an archaeological and cognitive perspective Émergence et complexification des pratiques symboliques dans la lignée Homo : une approche archéologique et cognitive

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Recent archaeological discoveries, reviewed in this essay, challenge traditional views on the emergence of human symbolic cognition. Once believed to have originated in Europe around 40,000 years ago, new evidence shows it emerged much earlier across diverse regions.
