Group living in species can have complex consequences for individuals, populations, and ecosystems. Therefore, estimating group density and size is often essential for understanding population dynamics, interspecific interactions, and conservation needs of group-living species. Spatial capture-recapture (SCR) has been used to model both individual and group density in group-living species, but modeling either individual-level or group-level detection results in different biases due to common characteristics of group-living species, such as highly cohesive movement or variation in group size.

Yet the resources for conservation are often limited and shared amongst many competing priorities [2]. As a consequence, even basic monitoring surveys are absent within most protected areas [3].

- The study examines how local mammalian carnivore communities impact terrestrial ecosystems by analyzing camera trap data from 12 countries across five continents, covering 108,087 trap days.
- Researchers found that certain species of carnivores tend to co-occur more often than expected, especially when they share ecological traits like body size, activity patterns, and diet.
- The presence of large carnivores influences these dynamics negatively, indicating that both shared traits and the presence of top predators regulate carnivore community structures globally.
Large-scale presence-absence monitoring programs have great promise for many conservation applications. Their value can be limited by potential incorrect inferences owing to observational errors, especially when data are collected by the public. To combat this, previous analytical methods have focused on addressing non-detection from public survey data.
