Ageing refers to the loss of organismal functionality with age, a process that is characterised by decreased reproduction and survival probability. In natural populations, it is expected that environmental conditions influence an individual's ageing trajectory. Understanding the role of environmental heterogeneity on ageing variation could provide critical insights into population resilience and species distribution but remains overlooked. Telomeres, the end cap of chromosomes, are a promising integrative physiological marker of an individual's health and a possible proxy to aid the understanding of variation in ageing trajectories. Here, we review the existing information on telomere length and its dynamics in wild populations distributed across spatial scales. Despite a relative scarcity of information, there is evidence for divergence in telomere length between populations facing contrasting environments. Nonetheless, a higher spatial resolution and temporal replication are needed to fully understand the role that environmental conditions play on telomere length variation. Since most of the existing studies are correlational, future field and laboratory experiments are required. For the first time, we demonstrate the use of population telomere data to predict species habitat suitability through species distribution models (SDMs). This represents a promising new research area in the study of ageing pattern variation in wild populations. Furthermore, the inclusion of telomere data in future physiological SDMs may improve our understanding of species distribution and population resilience. However, the use of telomeres within this context could be limited if no previous knowledge on the relevance of telomeres as markers of health and survival at the species level is available. Finally, we suggest some key practical and theoretical considerations that, ideally, future studies combining biogeographic and telomere data should pay attention. [ABSTRACT FROM AUTHOR]

Shared socioeconomic pathways are a key tool in predicting biodiversity scenarios and in the subsequent design of environmental policies. Here, we discuss how recent policy changes to global trade routes, agriculture, and energy production in response to the war in Ukraine are impacting socioeconomic scenarios used to set and assess biodiversity targets. We also discuss how the disruption to the global geopolitical landscape provides a window of opportunity for policy reform and the radical societal paradigm shift that is needed to tackle the global biodiversity crisis. We call for the re‐evaluation of biodiversity targets with newly developed scenarios that reflect the changes made to production and consumption patterns. We also recommend establishing national biodiversity working groups to screen proposed policies for their potential risks to the drivers of biodiversity change, since policy decisions made in response to the war that seemingly are far removed from the environment can have lasting impacts on nature.
