Abstract

Phenology of the regionally Critically Endangered dragonfly Urothemis edwardsii in the National Park of El Kala, Northeast of Algeria

Highlights

  • Biodiversity loss of insects has sparked a debate across the world (Wagner, 2020; Jähnig et al, 2021)

  • The current study provides useful information on the life history and plasticity of U. edwardsii, which could be used for the management of this locally Critically Endangered dragonfly

  • Scientists agree that climate change, habitat loss, and other anthropogenic stressors have driven extirpations of insect populations and potentially the extinction of multiple species (Hallmann et al, 2021; Raven & Wagner, 2021)

Summary

Introduction

Biodiversity loss of insects has sparked a debate across the world (Wagner, 2020; Jähnig et al, 2021). Scientists agree that climate change, habitat loss, and other anthropogenic stressors have driven extirpations of insect populations and potentially the extinction of multiple species (Hallmann et al, 2021; Raven & Wagner, 2021). The conservation of relict populations (distant populations from the core geographic range) is crucial because they bear a wealth of ecological and evolutionary information to scientists (Habel & Assmann, 2010; Habel et al, 2010). They represent living examples of the impact of major geological and climatic events on biodiversity (Hampe & Petit, 2005). Relict populations are very sensitive and their conservation is challenging because of the typically small population size, absence of immigration, and low potential of geographic shift
