New paper on functional trait space of arthropods along elevation with some interesting patterns 🐜🦗🪲🦋 ⛰️
basicapplecol.bsky.social Basic and Applied Ecology @basicapplecol.bsky.social · 22d
🦋🏔️ New article: How do arthropod traits shift with elevation?

Across four groups in Italy's Vinschgau Valley, orthopterans and butterflies lose trait diversity higher up, while ants gain it. 🐜

Fig. 1. The distribution of the traits body length, feeding type, wing development, and hibernation type of carabid beetles along Alpine elevation sites in Matsch/Mazia, South Tyrol (Italy). Numerical variables show mean CWM values of the variable per elevation and were tested with Kruskal Wallis rank-sum test (added in legend) followed by pairwise-Wilcoxon test. Categorical variables were also tested with Kruskal Wallis rank-sum test followed by pairwise Dunn test (significant results are shown with small letters). Credits for the icon: Eurac Research. Fig. 6. Overlap of pairs of hypervolumes indicated by the Sørensen index (0–1, where 1 is maximal similarity and 0 is no similarity). (A) The graph shows three comparisons on the X-axis of adjacent elevations, and (B) shows three comparisons along elevation starting always from the lowest elevation (1000 m) to all other elevations. (C) The photograph shows the silhouette of the actual sampled elevation sites in the LT(S)ER area "Matsch/Mazia". Please note: the lower part of the 1000 m was artificially extended due to perspectival reasons, and the locations of the sampling plots on this silhouette (yellow squares) are symbolic and do not represent their real location.

🎙️🐦 How does passive acoustic monitoring compare with traditional bird surveys? Across the Alps, PAM detected ~2× as many species—but varied across habitats. Our study explores how the two approaches differ and complement each other.

How Passive Acoustic and Traditional Monitoring Estimate Bird Diversity Across Habitats
We compared traditional bird counts (PC) with passive acoustic monitoring (PAM) in a heterogeneous Alpine landscape. PAM recorded twice as many species, with a strong correlation between species rich...

Our new Nature Eco Evo paper documents range shifts in 1,758 butterfly species across 105 countries, primarily due to climate change.

🦋80% expanded
🦋27% contracted
🦋22% shifted elevation
🦋342 showed multiple shift types.

Two weeks ago, we had our MonitAnt workshop with all project partners in the beautiful Bavarian Forest National Park. We even managed a short field trip, where everyone enjoyed being surrounded by wood ants and their myrmecophiles (see picture). 😉

Productive days in České Budějovice with @jiri-tuma.bsky.social and @eliaguariento.bsky.social, focusing on all aspects of camera traps for the MonitAnt project. We even squeezed in a wonderful trip to Šumava National Park.

Nature research paper: One mother for two species via obligate cross-species cloning in ants

go.nature.com/45PYV6d
One mother for two species via obligate cross-species cloning in ants - Nature
In a case of obligate cross-species cloning, female ants of Messor ibericus need to clone males of Messor structor to obtain sperm for producing the worker caste, resulting in males from the same mother having distinct genomes and morphologies.
