Following our failure to fully achieve any of the 20 Aichi biodiversity targets, the future of biodiversity rests in the balance. The Convention on Biological Diversity's Post-2020 Global Biodiversity Framework (GBF) presents us with the opportunity to preserve Nature's Contributions to People (NCPs) for current and future generations through conserving biodiversity and averting extinction across the Tree of Life. Here we demonstrate that species extinctions can lead to unequal losses of biodiversity depending on their evolutionary history, and call attention to our need to conserve the Tree of Life to maintain its benefits. We highlight two indicators available for adoption in the post-2020 GBF to monitor our progress towards safeguarding the Tree of Life. The Phylogenetic Diversity indicator, adopted by IPBES, can be used to monitor biodiversity's capacity to maintain NCPs. The EDGE (Evolutionarily Distinct and Globally Endangered) Index monitors how well we are performing at averting the greatest losses across the Tree of Life by conserving the most distinctive species. By committing to safeguarding the Tree of Life post-2020, we can reduce biodiversity loss and preserve nature's contributions to humanity now and into the future.

Habitat conversion is driving biodiversity loss and restructuring species assemblages across the globe. Responses to habitat conversion vary widely, however, and little is known about the degree to which shared evolutionary history underlies changes in species richness and composition. We analyzed data from 48 studies, comprising 438 species on five continents, to understand how taxonomic and phylogenetic diversity of amphibian assemblages shifts in response to habitat conversion. We found that evolutionary history explains the majority of variation in species’ responses to habitat conversion, with specific clades scattered across the amphibian tree of life being favored by human land uses. Habitat conversion led to an average loss of 139 million years of amphibian evolutionary history within assemblages, high species and lineage turnover at landscape scales, and phylogenetic homogenization at the global scale (despite minimal taxonomic homogenization). Lineage turnover across habitats was greatest in lowland tropical regions where large species pools and stable climates have perhaps given rise to many microclimatically specialized species. Together, our results indicate that strong phylogenetic clustering of species’ responses to habitat conversion mediates nonrandom structuring of local assemblages and loss of global phylogenetic diversity. In an age of rapid global change, identifying clades that are most sensitive to habitat conversion will help prioritize use of limited conservation resources.

Alternative prioritization strategies have been proposed to safeguard biodiversity over macroevolutionary time scales. The first prioritizes the most distantly related species—maximizing phylogenetic diversity (PD)—in the hopes of capturing at least some lineages that will successfully diversify into the future. The second prioritizes lineages that are currently speciating, in the hopes that successful lineages will continue to generate species into the future. These contrasting schemes also map onto contrasting predictions about the role of slow diversifiers in the production of biodiversity over palaeontological time scales. We consider the performance of the two schemes across 10 dated species-level palaeo-phylogenetic trees ranging from Foraminifera to dinosaurs. We find that prioritizing PD for conservation generally led to fewer subsequent lineages, while prioritizing diversifiers led to modestly more subsequent diversity, compared with random sets of lineages. Importantly for conservation, the tree shape when decisions are made cannot predict which scheme will be most successful. These patterns are inconsistent with the notion that long-lived lineages are the source of new species. While there may be sound reasons for prioritizing PD for conservation, long-term species production might not be one of them.

Apart from considerations of beneficence, we have reasons of at least four different kinds to ensure the survival of future generations under conditions conducive to human flourishing. This chapter explores two of those categories of reason: reasons of love and reasons of interest. Reasons of love rest on the fact that the fate of humanity matters to us in its own right. Reasons of interest appeal to our self-interest: that is, to our interest in leading lives engaged in worthwhile activities. These two categories of reason are conceptually independent, but it is partly because the future of humanity matters to us in its own right that the survival of future generations is in our interest.

The ongoing climate change and the unprecedented rate of biodiversity loss render the need to accurately project future species distributional patterns more critical than ever. Mounting evidence suggests that not only abiotic factors, but also biotic interactions drive broad-scale distributional patterns. Here, we explored the effect of predator-prey interaction on the predator distribution, using as target species the widespread and generalist grass snake (Natrix natrix). We used ensemble Species Distribution Modeling (SDM) to build a model only with abiotic variables (abiotic model) and a biotic one including prey species richness. Then we projected the future grass snake distribution using a modest emission scenario assuming an unhindered and no dispersal scenario. The two models performed equally well, with temperature and prey species richness emerging as the top drivers of species distribution in the abiotic and biotic models, respectively. In the future, a severe range contraction is anticipated in the case of no dispersal, a likely possibility as reptiles are poor dispersers. If the species can disperse freely, an improbable scenario due to habitat loss and fragmentation, it will lose part of its contemporary distribution, but it will expand northwards.

AbstractExperiments showed that biodiversity increases grassland productivity and nutrient exploitation, potentially reducing fertiliser needs. Enhancing biodiversity could improve P-use efficiency of grasslands, which is beneficial given that rock-derived P fertilisers are expected to become scarce in the future. Here, we show in a biodiversity experiment that more diverse plant communities were able to exploit P resources more completely than less diverse ones. In the agricultural grasslands that we studied, management effects either overruled or modified the driving role of plant diversity observed in the biodiversity experiment. Nevertheless, we show that greater above- (plants) and belowground (mycorrhizal fungi) biodiversity contributed to tightening the P cycle in agricultural grasslands, as reduced management intensity and the associated increased biodiversity fostered the exploitation of P resources. Our results demonstrate that promoting a high above- and belowground biodiversity has ecological (biodiversity protection) and economical (fertiliser savings) benefits. Such win-win situations for farmers and biodiversity are crucial to convince farmers of the benefits of biodiversity and thus counteract global biodiversity loss.

Biodiversity loss is progressing despite biodiversity being essential for human survival, prosperity, and well-being. Conservation, restoration, and sustainable use of the habitat, given that its change is the most prominent factor causing the deterioration of biodiversity, represents a highly effective way of securing biodiversity. Therefore, we assessed and monitored habitat quality as a proxy for biodiversity with habitat quantity in Jeju Island, South Korea. We used an InVEST model with data on the habitat type, suitability, sensitivity, accessibility, and threat factors. Natural habitats throughout Jeju had rapidly decreased in area by 24.9% from 1989 to 2019, and this change contributed to the degradation of habitat quality by 15.8%. We provided significant evidence on the critical degradation of habitat for a long period of over 30 years and highlighted the urgent need for policies and behaviors that enhance biodiversity. We proposed appropriate strategies to prompt people to conserve better, restore effectively, and use biodiversity sustainably. We expect that our findings will provide scientific and evidence-based guidance for policy-making on biodiversity enhancement and will further support achievement of the Sustainable Development Goals and Aichi Biodiversity Targets, in addition to compliance with the New Deal for Nature and People.

The UN's sustainable development goals (SDGs), which aim to solve important economic, social, and environmental problems of humanity, are to be supported by education for sustainable development (ESD). Empirical studies on the success of the implementation of the SDGs in the field of education are still pending. For this reason, using the loss of global biodiversity as an example, this study examined the extent to which high school students, teacher trainees in biology, and biology bachelor students can identify the causes of the global biodiversity loss. A new questioning tool was developed and tested on 889 participants. In addition, the relationship between connection to nature and the personal assessment about biodiversity threats was examined. The factor analysis of the scale used showed that 11 out of 16 items were assigned to the intended factor. The comparison between high school students, teacher trainees in biology, and biology bachelor students showed no significant difference in overall assessment of the reasons for global biodiversity loss. When comparing the three risk levels in which the risk factors for biodiversity could be divided, across the three student groups, only minor differences were found. Therefore, a specific education of prospective teachers is necessary, as they have to pass on the competence as multipliers to their students. No significant difference could be found when examining the relationship between connection to nature and the overall scores of the assessment scale for the reasons of biodiversity loss. However, it was found that people who felt more connected to nature were more capable of assessing the main causes of risk for global biodiversity, while people who felt less connected to nature achieved better scores for the medium factors.

LABURPENA: Gaur egun, mendien kudeaketa eta baso-politika ingurumeneko eta jasangarritasuneko irizpideetan oinarritzen dira, eta lurraldeko baliabide natural nagusiaren aprobetxamenduari buruzko erabakiak bideratzen dituzte. Hori dela-eta, lurralde-antolamendu ororen markoan, nekazaritzaren, basogintzaren eta abeltzaintzaren arloan jarduten duten eragile publiko eta pribatu guztiek egindako plangintza oinarrizkoa izango da hurrengoa bermatzeko: egun mendia behar bezala aprobetxatuz etorkizuneko belaunaldiei balio sozial eta ekonomiko bera transmititzen dien kudeaketa. RESUMEN: La gestión de los montes y la política forestal se fundamentan, actualmente, en criterios medioambientales y de sostenibilidad que dirigen las decisiones sobre el aprovechamiento del principal recurso natural del territorio. Por ello, en el marco de toda ordenación territorial, la planificación mediante la participación de todos los agentes públicos y privados que operan en el ámbito agrosilvopastoral se erige en instrumento esencial de las orientaciones garantizadoras de una gestión que, aprovechando óptimamente el monte en el presente, transmita ese mismo valor social y económico a las futuras generaciones. ABSTRACT: The management of forests and the forest policy are presently based on enviromental and sustainability criteria which are addressed to the decisions regarding the exploitation of the main natural resource of the territory. Because of it, in the framework of the whole territorial planning, the planning by the participation of all the public and private agents that operate within the agrarian, forest and herding field becomes an essential instrument of the guidelines that guaratee the management which using ideally the forest nowadays give that same social and economic value to the future generations.


Significance No substantive agreements emerged. Global targets to limit biodiversity loss were agreed in 2010, but all were missed and biodiversity loss has accelerated. The 'Kunming Declaration' does indicate some political will, but any enforceable delivery plans will have to wait for the second part of COP15 next year. Impacts The global biodiversity crisis is arguably as serious and pressing as the climate crisis. The low profile of COP15 shows that the severity of the problem is not yet widely recognised. The goal of making 30% of earth's land and seas 'protected' by 2030 provides new focus; disputes will focus on what it actually means. As host, Beijing will want to demonstrate success and will put pressure on other governments. Biodiversity is difficult even to measure, making is extremely challenging to create clear structures for accountable implementation.
