The latest European Grassland Butterfly Indicator is out. It shows that grassland butterflies have declined by 47% since 1991, indicating a huge loss of grassland biodiversity. The data come from 16,150 transects & 15,000 volunteers. We are calling for urgent action. www.bc-europe.eu/documents/69...

Wiley set to earn $44m from AI rights deals, confirms “no opt-out" for authors
The US publisher is the latest to capitalise on deals to give tech firms access to its authors’ content to train their Large Language Models (LLMs).
Everybody makes money out of academic authors except the authors...News.
Wiley is the latest academic publisher to reach a multi-million deal to allow access to its content to AI developers, with no opt out, let alone payment, for the authors who created that content.

Very happy to share our new paper published in Current Biology !
We show that the “big bad wolf” actually fears humans for good reason.
It’s the first-ever playback experiment on wild wolves in Europe 🇵🇱🌲.

Trait matching without traits: using correspondence analysis to investigate the latent structure of interaction networks
Species interactions in ecological communities are often represented as networks, the structure of which is thought to be linked to species' interaction niches (or Eltonian niches). Interaction niches are intimately related to the notion of trait matching, which posits that a species interacts preferentially with partners whose traits are complementary to their own. Multivariate methods are commonly used to quantify species environmental niches (or Grinnellian niches). More recently, some of these methods have also been used to study the interaction niche, but they consider only the niche optimum and require trait data. In this article, we use the correspondence analysis (CA) framework to study interaction networks and investigate trait matching without requiring trait data, using the notion of latent traits. We use reciprocal scaling, a method related to CA, to estimate niche optima and breadths, defined respectively as the mean and standard deviation of the latent traits of species' interacting partners. We present the method, test its performance using a simulation model we designed, and analyze a real frugivory network between birds and plants. The simulation study shows that the method is able to recover niche breadths and optima for data generated with parameters typical of ecological networks. The birds-plants network analysis shows strong relationships between species latent traits and niche breadths: a posteriori correlation with measured traits suggests that birds and plants of intermediate size tend to have the broadest niches. Additionally, birds preferentially foraging in the understory have broader niches than birds preferentially foraging in the canopy. CA and reciprocal scaling are described as fruitful exploratory methods to characterize species interaction profiles, provide an ecologically meaningful graphical representation of interaction niches, and explore the effect of latent traits on network structure. ### Competing Interest Statement The authors have declared no competing interest.

Of course, a latent approach means that the results can sometimes be difficult to interpret, and conflate different characteristics of species which are not generally considered as "traits". But I still think CA and reciprocal scaling are interesting approaches to analyze interaction networks. (5/6)

Figure 7 from the article: Correlation circle measured a posteriori between species measured and latent traits. Bird traits are shown in solid red lines and plant traits in dashed blue lines. Axis 1 shows a size effect while axis 2 is defined by the matching between plant height and Kipp’s index.
We also find out that the axes are fairly related to some species' traits thought to be related to trait matching: beak width and fruit diameter, body mass and crop mass, and Kipp's index and plant height. This suggests that this latent trait approach captures known trait matching patterns! (4/6)

Figure 5 from the article. Reciprocal scaling of the birds-plants interaction network. Points correspond to the interaction scores h_k(i, j) in the first 2 dimensions, grouped by bird (a) or plant species (b). Species label are placed at the reciprocal scaling mean, and ellipses correspond to the bivariate normal distribution with variances and covariances given by reciprocal scaling (with a scaling factor of 1.5, i.e. the ellipse axes lengths are equal to 1.5*sqrt(λk) on axis k, corresponding to around 67% of the points contained in the ellipse). Ellipses are colored according to the rank of their centroid on the first axis. The correspondence between species’ codes and names is given in Appendix D.
We use a simulation approach to test the method, and illustrate it on a bird-plant frugivory network. Below are species' niches in the multivariate space for birds and plant species interacting in this network. (3/6)

Figure 1 from our article: Visualization of the interaction niche in a 2-dimensional space. The niche is depicted by an ellipse whose center represents niche optima and semi-axes represent niche breadths. The angle of the ellipse represents the covariance between niche axes. Points represent interaction scores.
In this article, we relate the interaction niche to trait matching. For that, we use reciprocal scaling, a method related to correspondence analysis, which allows to represent species' niches in the multivariate space and where the multivariate axes can be interpreted as latent traits. (2/6)

Moving functional network ecology forward (without traits)
Is it possible to infer trait matching in ecological networks, even when no trait information is available? In our new article, just recommended by Timothée Poisot (@ctrlalttim.com) for PCI Ecology, we suggest that it is possible! Read the recommendation here: doi.org/10.24072/pci... 🌐 (1/6)
