As the biodiversity crisis accelerates, stakes are higher for threatened plants and animals. Rebuilding health of our planet will require addressing underlying threats at many scales, including habitat loss climate change. Conservation interventions such as protection, management, restoration, predator control, translocation, genetic rescue, biological control have potential to help or endangered species avert extinction. These existing, well-tested methods can be complemented augmented by more frequent faster adoption new technologies, powerful tools. In addition, synthetic biology might offer solutions currently intractable conservation problems. We believe that needs bold clear-eyed in this moment great urgency. Proposed efforts mitigate often raise concerns about potentially harmful unintended consequences. For some highly documented strategies based on principles, translocations, restoration natural fire regimes, evidence date suggests careful planning produces intended consequences while avoiding adverse example, better identification mitigation risks has resulted no severe, negative, translocations releases over last 30 years United States (Novak et al., 2021).

Abstract Understanding the neutral (demographic) and adaptive processes leading to differentiation of species populations is a critical component evolutionary conservation biology. In this context, recently diverged taxa represent unique opportunity study process genetic differentiation. Northern southern Idaho ground squirrels ( Urocitellus brunneus —NIDGS, U . endemicus —SIDGS, respectively) are pair sister that have undergone dramatic declines in last 50 years currently found metapopulations across restricted spatial areas with distinct environmental pressures. Here we genotyped single‐nucleotide polymorphisms (SNPs) from buccal swabs restriction site‐associated DNA sequencing (RADseq). With these data evaluated structure at both inter‐ intraspecific level, identified putatively SNPs using population outlier detection genotype–environment association (GEA) analyses. At interspecific detected clear separation between NIDGS SIDGS, evidence for linked torpor patterns. For NIDGS, elevation appears be main driver differentiation, while variation patterns match expand information on low connectivity some previous studies microsatellite markers. substructure generally reflected natural geographical barriers, differences land cover temperature, as well elevation. These results clearly highlight roles understanding complexity which can important implications susceptible threatened species.

Abstract Translocation, the human‐mediated movement of organisms from one area to another, is a popular tool in conservation management. Wild‐caught individuals are more likely persist following release than those sourced captive breeding. However, this benefit obtaining wild populations must be carefully weighed against potential harm viability source populations. In structured review, we assess peer‐reviewed primary literature that addresses wild‐sourced translocation programs. We aim determine what proportion studies make priori estimates impact harvesting on populations, provide quantitative evidence demographic trends harvest, and which methods being used impacts Of 292 articles reviewed, identified just 32 instances (11%) where population was estimated. The given year has not increased over time. explicit comparisons alternative strategies becoming frequent. propose standardized framework for reporting management Published summaries translocations should include clear goals, description impact, an justification based chosen strategy, estimated timeline recovery summary postremoval efficacy assessment.
