Papers like this really underscore the importance of long term monitoring datasets for understanding climate change impacts on biodiversity... And highlight the dire consequences of even modest temperature increases. 🧪🌍🦤🦜

🍃¿Puede ayudar aliarnos con la ecología a prevenir una pandemia? El investigador del #CSIC en el @mncn-csic.bsky.social Fernando Valladares profundiza en este tema en una entrevista en @aventurasaber 👇📺
The image shows at the top left, the map with the 26 localities spanning the wide range of environmental conditions across Iberian Spain. At the bottom left, a photo of a juvenile Eurasian blackcap together with a rectangle showing the codes that indicate the progress of the post-juvenile moult (from 1 to 6) and the summary of the main results (lower moult scores indicative of delayed moult in birds with Plasmodium, Haemoproteus and high-Haemoproteus parasite load). At the top right there is the Figure 2 of the paper with the mean posterior probability and 95% Bayesian credible intervals (BCI) of each stage of PJM (represented with different colours) in juvenile blackcaps that were either uninfected, single-infected or co-infected by any haemosporidian lineage. And finally, at the bottom right there is the figure 3 of the paper with the relationship between the Haemoproteus intensity and the posterior probability of each post-juvenile moult score.

In nature time is precious. We discovered that young of a small passerine bird, the Eurasian blackcaps, infected by haemosporidians, commonly known as avian malaria parasites, were delayed in the moult that confers these birds an adult plumage.
For birds, a delayed postjuvenile moult may have carry-over effects on Darwinian fitness, as acquiring late the adult plumage can interfere with the protective or signalling functions of the plumage, or with the scheduling of migration.

The relationship is robust because it comes from a study of 26 Iberian populations of blackcaps, which face high parasite prevalence from very early ages, spanning a broad range of environments.
