Perspectives

This Perspective provides guidance about how to select the most appropriate type of interaction network for different research questions in ecology. Networks can vary according to the extent of node aggregation and the information that links represent; each kind of network formulation has advantages in different contexts.

Aquatic eDNA-based technologies offer the potential for universal and standardized biodiversity monitoring. In this Perspective, Altermatt et al. discuss how these technologies can help to achieve the targets of the Kunming–Montreal Global Biodiversity Framework through informing appropriate policy and actions, and describe the next steps required for widespread and equitable use of these technologies.

Parasites and their hosts can have complex ecological interactions and evolutionary histories. This Perspective argues that parasites are a major driver of host speciation and outlines an empirical framework for testing this hypothesis.

The mycorrhizal symbiosis between plants and fungi is critical to the success of both partners. This Perspective explores how plant reliance on mycorrhizae varies across ecological scales and how the relationship shifts with changing ecological conditions.

In this Perspective, the authors explore several aspects that have shaped the practice of animal conservation translocation. They describe factors influencing how and where conservation translocation is applied, current challenges in the application and assessment of conservation translocation, and future implications of ‘de-extinction’ and the rise of synthetic biology.

Conservation efforts can be directed at multiple ecological scales, from species to ecosystems. This Perspective calls for conservation at the scale of ecological communities or assemblages and discusses the data and modelling advances that enable progress at this scale.

Wildlife are central to nature’s contributions to people (NCP) but are often overlooked in NCP policy and management. This Perspective presents evidence for the integral role of wildlife in supporting human well-being and proposes their recognition and incorporation into conservation decision-making as wildlife’s contributions to people (WCP).
