Behavioural and fitness effects of experimental immune activation during incubation in a wild passerine

Ibis, EarlyView.
Incubation is vital for avian embryo development but demands significant parental investment, potentially at the cost of self‐maintenance and immune function. For example, the acute phase response (APR), a systemic reaction against inflammation, infection or tissue injury, can trigger sickness behaviours such as reduced activity and foraging.

Reproductive consequences of mate retention and divorce in a short‐lived migratory passerine

Ibis, EarlyView.
In socially monogamous birds, pair‐bond duration varies across species, from single‐breeding associations to long‐lasting, multi‐year bonds. Studies of pair retention and divorce have focused on long‐lived and sedentary species rather than short‐lived and migratory species.

Population Response to Habitat Management from an Endangered Galliform: The Pyrenean Grey Partridge Recovery Project in Lago de Sanabria (2000–2023)

Diversity
The Pyrenean grey partridge (Perdix perdix hispaniensis) is an endangered and insufficiently studied galliform occurring in upland habitats dominated by shrublands in Spain, France, and Andorra. Aiming to develop tailored management to favour the species,

Exploring drivers and costs of partial trans‐Saharan migration in juvenile vultures

Ibis, EarlyView.
Partial migration occurs when only a subset of individuals within a population undertakes a migratory journey. The decision to migrate can be influenced by intrinsic traits (e.g. sex or physical condition) as well as by extrinsic factors (e.g. social environment or resource availability).

Fine‐scale genetic structure in co‐operatively breeding Palmchats (Dulus dominicus) suggests mixed kinship in compound nests

Ibis, EarlyView.
Fine‐scale genetic structure in animal populations can create opportunities for both kin‐directed co‐operation and kin competition. Knowledge of kinship is therefore key to understanding the selective pressures shaping sociality as well as the effects of social behaviour on local genetic structure.

Expanding the Fish‐Brain Invitrome With the Senegalese Sole SsB‐1 Cell Line—A Versatile Model for Neurotropic Virus Research

Journal of Fish Diseases, EarlyView.
ABSTRACT Cell lines are essential tools for studying animal physiology and immunopathology, reducing the use of live animals and supporting the 3Rs principle of reduction, refinement, and replacement. The Senegalese sole (Solea senegalensis), a relevant species for Spanish aquaculture diversification, lacks established in vitro models. We developed SsB‐
