An Atlantic Puffin stands on a narrow, rocky cliff ledge streaked with lichen and tufts of grass. Its black back and white chest contrast with the pale stone, and its bright orange bill catches the light. The blurred backdrop of steep coastal rock faces hints at a rugged seabird colony, one of the special coastal habitats that provide vital nesting sites for wildlife.

Which is why the habitats they fight to return to must be protected.

Weakening protections for key sites for nature would push our already struggling wildlife closer to collapse.

Yet the UK Government is considering doing just that.

Scary how many #MicrobiomeSky studies ignore this
"Ecological data are inherently noisy and sparse [...] As such, it is not unexpected that robust inference of complex ecological processes like species interactions necessitates large sample sizes."

In the simplest scenario, there is high bias in the interaction parameter (used for co-occurrence inference) with less than 100 sites at high detection, and 400–1000 sites at low detection, depending on interaction strength. Strong co-occurrence is detected consistently above 200 sites with high detection probabilities, but weak co-occurrence is never consistently detected even with 2980 sites. We demonstrate that the mean predictive ability of the co-occurrence model is less affected by sample size

🚨 So "How many sites do I need"? The answer = it depends on inference objective! We provide recommended minimum sample sizes for different contexts based on our simulation outputs here ⬇️ P.s. all our code is freely available on OSF, so have a play around!

Take home 4: In all scenarios, far fewer sites were needed to estimate the conditional and marginal occupancy probabilities (i.e. prediction), compared to the exact interaction term (i.e. inference)

Take home 3: Adding covariates to the model also upped the sample sizes needed to estimate interaction terms without bias πŸ’»πŸŒ²

Take home 2: Adding more species to the models reduced the power to detect interactions of a similar strength. For example, a null model with 5 species needed 400 sites compared to 250 sites with 3 species

Take home 1: Under the simplest model structure, we needed around 200 sites to detect and estimate strong interactions without bias. These requirements increased when (1) detection probability was lower and (2) species interactions were weaker

We did an extensive simulation study to show how well the Rota et al multispecies occupancy model estimates interaction terms under different detection probabilities, interaction strengths, interaction directions (positive/negative) and model structures, from 20 to ~3000 sites
