Este comentario resalta la importancia que el análisis de secuencias de ADN tiene en los estudios de biodi-versidad y la necesidad de mejorar los procedimientos administrativos concernientes a las investigaciones de biodiversidad en el Perú. La rápida pérdida de la biodiversidad y recursos naturales del Perú justifican la urgencia de apoyar aquellas investigaciones que ayuden a identificar, describir y caracterizar a la biodiversidad en la brevedad posible, para que se puedan tomar las debidas medidas de conservación y mitigación. Enfatizamos la importancia del uso de técnicas modernas dentro del modelo de estudio de la taxonomía integradora, incluyendo el estudio de los procesos evolutivos asociados a áreas con mayor diversidad y endemismo y los efectos del cambio climático sobre la biodiversidad peruana. Asimismo, es esencial que las entidades gubernamentales encargadas de evaluar los planes, solicitudes y requisitos asociados a las investigaciones de la biodiversidad del Perú reconozcan y apoyen el enfoque de la taxonomía integradora. El uso de técnicas modernas dentro del modelo de la taxonomía integradora, junto a procedimientos administrativos eficientes, puede convertirse en la mejor herramienta para proteger la biodiversidad peruana. ; This commentary focuses on the importance that DNA sequence analysis has in biodiversity studies and the need for improving administrative procedures regarding biodiversity research in Peru. Given the rapid loss of biodiversity and natural resources in many areas of Peru, research aimed at identifying, characterizing, and describing biodiversity is a priority for developing appropriate conservation and mitigation strategies. For cur-rent and future research on Peruvian biodiversity and conservation, we emphasize the importance of using an integrative taxonomy approach, including the study of evolutionary processes associated with areas of high biodiversity and endemism. Additionally, it is essential that governmental institutions responsible for review-ing permit applications and research plans, focusing on biodiversity research in Peru, recognize and support studies that incorporate an integrative taxonomy approach. The use of modern techniques in the integrative taxonomy model in conjunction with efficient administrative procedures will be the best method for protecting Peruvian biodiversity.

Governments have committed to conserving ≥17% of terrestrial and ≥10% of marine environments globally, especially "areas of particular importance for biodiversity" through "ecologically representative" Protected Area (PA) systems or other "area-based conservation measures", while individual countries have committed to conserve 3-50% of their land area. We estimate that PAs currently cover 14.6% of terrestrial and 2.8% of marine extent, but 59-68% of ecoregions, 77-78% of important sites for biodiversity, and 57% of 25,380 species have inadequate coverage. The existing 19.7 million km2 terrestrial PA network needs only 3.3 million km2 to be added to achieve 17% terrestrial coverage. However, it would require nearly doubling to achieve, cost-efficiently, coverage targets for all countries, ecoregions, important sites, and species. Poorer countries have the largest relative shortfalls. Such extensive and rapid expansion of formal PAs is unlikely to be achievable. Greater focus is therefore needed on alternative approaches, including community- and privately managed sites and other effective area-based conservation measures.

Some conservation prioritization methods are based on the assumption that conservation needs overwhelm current resources and not all species can be conserved; therefore, a conservation triage scheme (i.e., when the system is overwhelmed, species should be divided into three groups based on likelihood of survival, and efforts should be focused on those species in the group with the best survival prospects and reduced or denied to those in the group with no survival prospects and to those in the group not needing special efforts for their conservation) is necessary to guide resource allocation. We argue that this decision‐making strategy is not appropriate because resources are not as limited as often assumed, and it is not evident that there are species that cannot be conserved. Small population size alone, for example, does not doom a species to extinction; plants, reptiles, birds, and mammals offer examples. Although resources dedicated to conserving all threatened species are insufficient at present, the world's economic resources are vast, and greater resources could be dedicated toward species conservation. The political framework for species conservation has improved, with initiatives such as the UN Sustainable Development Goals and other international agreements, funding mechanisms such as The Global Environment Facility, and the rise of many nongovernmental organizations with nimble, rapid‐response small grants programs. For a prioritization system to allow no extinctions, zero extinctions must be an explicit goal of the system. Extinction is not inevitable, and should not be acceptable. A goal of no human‐induced extinctions is imperative given the irreversibility of species loss.

Darwin's frogs Rhinoderma darwinii and Rhinoderma rufum are the only known species of amphibians in which males brood their offspring in their vocal sacs. We propose these frogs as flagship species for the conservation of the Austral temperate forests of Chile and Argentina. This recommendation forms part of the vision of the Binational Conservation Strategy for Darwin's Frogs, which was launched in 2018. The strategy is a conservation initiative led by the IUCN SSC Amphibian Specialist Group, which in 2017 convened 30 governmental, non-profit and private organizations from Chile, Argentina and elsewhere. Darwin's frogs are iconic examples of the global amphibian conservation crisis: R. rufum is categorized as Critically Endangered (Possibly Extinct) on the IUCN Red List, and R. darwinii as Endangered. Here we articulate the conservation planning process that led to the development of the conservation strategy for these species and present its main findings and recommendations. Using an evidence-based approach, the Binational Conservation Strategy for Darwin's Frogs contains a comprehensive status review of Rhinoderma spp., including critical threat analyses, and proposes 39 prioritized conservation actions. Its goal is that by 2028, key information gaps on Rhinoderma spp. will be filled, the main threats to these species will be reduced, and financial, legal and societal support will have been achieved. The strategy is a multi-disciplinary, transnational endeavour aimed at ensuring the long-term viability of these unique frogs and their particular habitat. ; Zoo Leipzig Huilo Huilo Foundation Universidad Andres Bello Fundacion MERI Forestal Arauco Darwin Vineyards Comision Nacional de Investigacion Cientifica y Tecnologica (CONICYT) CONICYT FONDECYT 1181758 3180107 ; Versión publicada - versión final del editor
