Species Associations in a Changing World

Species associations will change as the climate rises. So how can we attempt to predict these changes

The Crux

Statistical modelling is a crucial part of ecology. Being able to provide an (admittedly simplified) mathematical description of the relationship between species abundance, range or density and the surrounding environment is a huge help in taking proactive steps to manage an ecosystem, or predicting species numbers in other areas.

Historically models have used environmental variables to explain population or evolutionary developments in species. When modelling a single species, many ecologists have taken into account that the presence of other species (for example competitors or predators) may influence the presence of this single species. This has led to the rise of joint species distribution models (JSDMs), which take into account environmental variables, as well as the interactions between certain species. These models have become increasingly useful, and with environmental change now being the norm in many ecosystems, this week’s authors produced one such model that accounts for changes in species interactions in the face of changing environmental factors.

Matt von Konrat: Harnessing Community Science

Matt von Konrat has been using community science at the Chicago Field Museum to generate data that it would have taken years for a single research team to produce, and engaging the public at the same time

Public engagement is something I’ve spoken about at length with the scientists I’ve been fortunate enough to talk to. However communicating better with the public is one thing; actively getting them involved in the scientific process is another. Matt von Konrat, of the Chicago Field Museum, has led an ambitious project which has successfully involved thousands of Americans from all walks of life in the scientific gathering of data. The result? Millions of specimens quantified, and thousands of people left with a better understanding of science.
