Species co-occurrences have long been used as proxies for interactions, but not all co-occurring species interact. A study now reveals that super-generalist consumers realize a higher portion of their potential interactions in bipartite networks.

Data from 5,525 in-water reef fish surveys conducted between 1- and 30-m depth reveal predictable depth-dependent zonation across the Pacific Ocean, particularly in the absence of a local human population. By contrast, relationships between depth and biomass were reduced or absent at populated islands, which suggests a human impact on depth-dependent ecological organization.

Sara Middleton explains how automated image segmentation can be used to rapidly identify objects and regions of interest to enable the monitoring of vegetation changes.

Across taxa, increased temperature has been reported to generally reduce individual body size and change the body size structure of wild communities. Our research reveals that the effects of climate warming on the body size structure of stream fishes are also dependent on the intensity of other human pressures.

For a long time, the ecological niche concept was less popular for microbes than for other organisms. A new proxy for the ecological niche breadth of a microorganism, based on the variability of the communities with which it associates, enables investigation of the correlates of being a social generalist or social specialist.
