Proud to share our work on frogs' dynamics with the chytrid pathogen during climate-driven range expansion (tinyurl.com/climateshift...). Many species are undergoing climate-driven shifts, & the incidence of emerging infectious disease events has also increased. How do the two interact? (1/7)

Have you heard of the incredible 🌈 of color variation in Boca del Toro, Panama, in strawberry poison frogs, which elsewhere in their range live up to their name & are just 🍓-colored? It was a joy to be part of a new study addressing this perplexing system, led by Dr @dianaguilr.bsky.social.

New paper from me + @lauradee.bsky.social on using causal inference methods and concepts in ecology! onlinelibrary.wiley.com/doi/10.1111/... (1/5)
Two directed acyclic graphs showing causal relationships. The first shows a simple relationship between the presence of rare plant species (x), illustrated with icons of individual plants, and grassland productivity (y), illustrated with icons of grasses. There is an arrow going from x to y. The second shows the same relationship, but this time with omitted variables (u). The omitted variables include observed omitted variables (like precipitation) and unobserved omitted variables (like legacies of agricultural activity). These are illustrated with an icon of a rain cloud, a fence, and a shovel. There are dashed arrows going from the omitted variables to both x and y.

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold. We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940. 2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.
Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.
