Enhancing disciplinary diversity and inclusion in conservation science and practice based on a case study of the Society for Conservation Biology.

Effective conservation requires a variety of perspectives that center on different ways of knowing. Disciplinary diversity and inclusion (DDI) offers an important means of integrating different ways of knowing into pressing conservation challenges. However, DDI means more than multiple disciplinary approaches to conservation; cognitive diversity and epistemic justice are key.

A framework for promoting disciplinary diversity and inclusion through epistemic justice.

Integrating diverse disciplines and knowledge practices into conservation offers new insights into the complex socioecological dynamics of conservation challenges and how to address them. Integration, however, is not simple; disciplines differ widely in their epistemic and professional commitments, theories, methods, applications, practices, and codes of ethics. Using an epistemic justice approach, we examined how and why different forms of disciplinary and social diversity are connected and offer a framework for promoting disciplinary diversity for conservation science and practice.

Space-for-time substitutions exaggerate urban bird-habitat ecological relationships.

North American bird abundance has declined by 29% over the last 50 years. These continental population dynamics interact with local landscape changes to affect local bird diversity. Mitigating local declines in cities is particularly significant because (a) such declines greatly impact human-bird relationships since most people live in cities and (b) cities provide levers to create bird-friendly habitat, such as managing yards and gardens, street trees, and urban parks.

Can internal range structure predict range shifts?

Poleward and uphill range shifts are a common-but variable-response to climate change. We lack understanding regarding this interspecific variation; for example, functional traits show weak or mixed ability to predict range shifts. Characteristics of species' ranges may enhance prediction of range shifts.

Applying a deep learning pipeline to classify land cover from low-quality historical RGB imagery.

Land use and land cover (LULC) classification is becoming faster and more accurate thanks to new deep learning algorithms. Moreover, new high spectral- and spatial-resolution datasets offer opportunities to classify land cover with greater accuracy and class specificity. However, deploying deep learning algorithms to characterize present-day, modern land cover based on state-of-the-art data is insufficient for understanding trends in land cover change and identifying changes in and drivers of ecological and social variables of interest.

Wild hummingbirds discriminate nonspectral colors.

Many animals have the potential to discriminate nonspectral colors. For humans, purple is the clearest example of a nonspectral color. It is perceived when two color cone types in the retina (blue and red) with nonadjacent spectral sensitivity curves are predominantly stimulated.

I see your false colours: how artificial stimuli appear to different animal viewers.

The use of artificially coloured stimuli, especially to test hypotheses about sexual selection and anti-predator defence, has been common in behavioural ecology since the pioneering work of Tinbergen. To investigate the effects of colour on animal behaviour, many researchers use paints, markers and dyes to modify existing colours or to add colour to synthetic models. Because colour perception varies widely across species, it is critical to account for the signal receiver's vision when performing colour manipulations.

Camouflage and Clutch Survival in Plovers and Terns.

Animals achieve camouflage through a variety of mechanisms, of which background matching and disruptive coloration are likely the most common. Although many studies have investigated camouflage mechanisms using artificial stimuli and in lab experiments, less work has addressed camouflage in the wild. Here we examine egg camouflage in clutches laid by ground-nesting Snowy Plovers Charadrius nivosus and Least Terns Sternula antillarum breeding in mixed aggregations at Bahía de Ceuta, Sinaloa, Mexico.
