SummaryWe propose an approach to conservation centred on achieving positive future trajectories of dynamic change, applied to all locations and species, and based on societal inclusiveness. Strategies to facilitate change. We take an Anthropocene perspective, in which human society and biodiversity have been inextricably linked for over 10,000 years, and continuing biodiversity change is inevitable. The challenge is to identify circumstances under which change is acceptable or beneficial, without being tied to specific historic baselines. We outline a Resist-Accept-Facilitate (RAF) framework that could be applied to all conservation activities, from high-level planning and measurement (indicators) through to practical land and species management, to ensure that the facilitation of future biodiversity benefits receives as much attention as the resistance of change.Everywhere is important. Different places are important for different things, such as particular species or ecosystem services, and people vary in how they value these features. We suggest a perspective whereby we evaluate what every area is most important for, and what they could be most important for in future by considering possible trajectories of biodiversity and ecosystem change. We propose zoning any region of interest, such as the UK, and applying the RAF framework in an inclusive manner to develop conservation strategies that are appropriate in each location and zone. This RAF approach will reconcile different conservation philosophies (such as traditional management, land-sharing/sparing, rewilding, novel ecosystems, ecosystem services, human wellbeing) because different conservation outcomes will emerge in different zones.Enabling species to move. Genes and species undertake changes to their abundances and distributions in response to climatic and other environmental changes. We suggest that trans situ conservation be developed as a complement to traditional in situ (sites in the wild) and ex situ (in captivity) conservation. Trans situ conservation primarily involves Accept and Facilitate interventions within the RAF framework. It requires consideration of the connectedness and permeability of regions (facilitating colonisation for a majority of species and genes) and the value of new populations of colonising species and novel communities that arise from species range shifts. Trans situ conservation also considers the potential to translocate (assisted colonisation) species and genes that are unable to shift their distributions without direct intervention, highlighting the transnational needs of globally-threatened species rather than locally-rare ones whose future is secure elsewhere.For everyone. The justification for conservation commonly focuses attention on the benefits that individuals and society derive from the natural world, yet the benefits are not shared equitably. The RAF approach asks people from a wide range of backgrounds ‘what they want’ from local landscapes so as to inform the development of more inclusive approaches to conservation both now and in the future. We identify ways in which the processes of conservation could incorporate an increased diversity of perspectives, whilst continuing to be informed by data and professional expertise.

Over the past 1000 years, rats ( Rattus spp.) have become one of the most successful and prolific pests in human society. Despite their cosmopolitan distribution across six continents and ubiquity throughout the world's cities, rat urban ecology remains poorly understood. We investigate the role of human foods in brown rat ( Rattus norvegicus ) diets in urban and rural areas over a 100 year period ( ca AD 1790–1890) in Toronto, Canada using stable carbon ( δ 13 C) and nitrogen ( δ 15 N) isotope analyses of archaeological remains. We found that rat diets from urban sites were of higher quality and were more homogeneous and stable over time. By contrast, in rural areas, they show a wide range of dietary niche specializations that directly overlap, and probably competed, with native omnivorous and herbivorous species. These results demonstrate a link between rodent diets and human population density, providing, to our knowledge, the first long-term dietary perspective on the relative value of different types of human settlements as rodent habitat. This study highlights the potential of using the historical and archaeological record to provide a retrospective on the urban ecology of commensal and synanthropic animals that could be useful for improving animal management and conservation strategies in urban areas.

Africa’s large mammals are conserved for their aesthetic, scientific and economic values. Many of these species face a gloomy future precipitated by a combination of factors directly and indirectly influenced by the activities of man, including habitat loss, overexploitation, poor management of designated protected areas, and the vulnerability of small isolated populations. Africa’s designated protected areas and biodiversity hotspots are also under threat, highlighting the importance of embracing community participation to address accelerating poverty and malnutrition. Innovative strategies are required for the conservation of Africa’s mammals, such as the integration of a wide range of species in the production landscape, including the farming community. Transfrontier conservation areas (TFCAs) have been established with the combined objectives of conserving biodiversity, creating new jobs in the tourism and wildlife industry, and promoting a culture of peace. These areas extend far beyond traditional national parks, providing opportunities for integrating large mammals into sustainable land-use practices, at the same time as addressing some of the continent’s more pressing socioeconomic needs. Research on African mammals will inevitably have to change direction to accommodate the growing threats and changed circumstances. Priorities will include the identification of corridors associated with TFCA establishment, the determination of the economic value of certain species in consumptive use programmes, research on contraception as a management option in restricted areas, and further work on the indirect use value of species. There will also be worthwhile opportunities to be pursued with ex situ conservation programmes, but these need to be focussed more efficiently.

AbstractGlobal biodiversity is projected to further decline under a wide range of future socio-economic development pathways, even in sustainability oriented scenarios. This raises the question how biodiversity can be put on a path to recovery, the core challenge for the CBD post-2020 global biodiversity framework. We designed two contrasting, ambitious global conservation strategies, ‘Half Earth’ (HE) and ‘Sharing the Planet’ (SP), and evaluated their ability to restore terrestrial and freshwater biodiversity and to provide ecosystem services while also mitigating climate change and ensuring food security. We applied the integrated assessment framework IMAGE with the GLOBIO biodiversity model, using the ‘Middle of the Road’ Shared Socio-economic Pathway (SSP2) with its projected human population growth as baseline.We found that both conservation strategies result in a reduction in the loss of biodiversity and ecosystem services globally, but without additional measures to achieve effective climate mitigation they will be insufficient to restore biodiversity. The HE strategy performs better for terrestrial biodiversity protection (biodiversity intactness (MSA), Red List Index, geometric mean abundance) in currently still natural regions, reflecting global conservation priorities. The SP strategy yields more improvements for biodiversity in human-used areas, aquatic biodiversity and for regulating ecosystem services (pest control, pollination, erosion control), reflecting regional priorities. However, ‘conservation only’ scenarios show a considerable increase in food security risks (especially in Sub-Saharan Africa) compared to the baseline and limited reduction of global temperature increase. Only when conservation strategies are combined with climate change mitigation efforts and additional actions especially in the agricultural and energy system into a portfolio of ‘integrated sustainability measures’, both conservation strategies result in restoring biodiversity to current values or even some improvement, while keeping global warming below two degrees and keeping food security risks below baseline. Minimizing food wastes and reducing consumption of animal products will be crucial.

Wetlands as other ecosystems deliver goods and services of enormous value to the human society and are regarded as one of the most productive ecosystems. We assessed the ecosystem services delivered by Bishajari Lake and its associated wetland areas of Chitwan district during June to August, 2012. A household survey consisting 110 households, interviews with key informants, group discussions and stakeholder analysis were carried out for this purpose to document the overall status of ecosystem services, evaluate the provisional services generated by the lakes, understand potentials for payment to ecosystem services, and identify stakeholders involved and their roles and responsibilities. A total of 12 fish species, 17 wild and domestic fruits, 12 timber species, 15 fodder species, 20 wild vegetables species and 31 medicinal plant species were recorded. Moreover 65.5% of respondents were found receiving some sort of income from the wetland area. The majority of respondents felt that the ecosystem is being changed mostly on provisional services. So far with little support from government, the local people have practiced some adaptive responses like biogas plant, afforestation, electric fencing, contract fisheries, ecotourism and other climate-smart measures. It suggest that raising awareness and sharing information among the locals should be done more frequently and effectively to continuously cope with ecosystem change.

AbstractThe odonates are insects that have a wide range of reproductive, ritualized territorial, and aggressive behaviors. Changes in behavior are the first response of most odonate species to environmental alterations. In this context, the primary objective of the present study was to assess the effects of environmental alterations resulting from shifts in land use on different aspects of the behavioral diversity of adult odonates. Fieldwork was conducted at 92 low-order streams in two different regions of the Brazilian Amazon. To address our main objective, we measured 29 abiotic variables at each stream, together with five morphological and five behavioral traits of the resident odonates. The results indicate a loss of behaviors at sites impacted by anthropogenic changes, as well as variation in some morphological/behavioral traits under specific environmental conditions. We highlight the importance of considering behavioral traits in the development of conservation strategies, given that species with a unique behavioral repertoire may suffer specific types of extinction pressure.

Abstract Background: Genetic diversity is needed to preserve the capability of a species to survive to environmental changes. Due to the presence of small isolated populations, relict species such as Magnolia are at an elevated extinction risk. In recent years, many new species of Magnolia have been described in Mexico, each one classified by its category of risk. To achieve conservation, knowledge of their basic level of biological diversity is essential to design adequate conservation plans and avoid the negative consequences of genetic loss. Here, we implemented nuclear microsatellite markers to assess 13 populations of three new species of Magnolia that were all previously considered to be Magnolia pacifica. We aimed to evaluate the genetic agreement with the distinction of these three different morphological species (e.g., their species integrity) and to determine their levels of genetic diversity and their geographic distribution to propose conservation strategies. Results: We found high levels of genetic diversity compared to other Magnolia species with no sign of inbreeding. We found a small effective population size and a prevalence of bottlenecks in some populations. The patterns of genetic subdivision did not support the current morphological distinction of three different species. Instead, we suggest that the genetic structure pattern is the result of historical connectivity and the continuous natural fragmentation of the forest. Thus, an isolation by distance pattern may have had an important role in shaping allele frequencies, producing local genetic differences. Conclusions: We argue that a major threat underlies the actual trends of habitat loss, which can directly impact the loss of genetic diversity in the current adult individuals and consequently, increase the risk of extinction in further generations. For conservation purposes, we suggest combining in situ and ex situ conservation of populations with the maintenance of connectivity among the local populations.

In this paper we are analyzing the potential of land cover features to provide three regulating ecosystem services (ESs), ES Local climate regulation, ES Water quality regulation and ES Biodiversity promotion, in two case study areas: Special nature reserve (SNR) Obedska bara (Serbia) and Protected landscape area (PLA) Dunajske luhy (Slovakia). Regulating ESs are not only important for proper functioning of ecosystems, but they are also crucial for the existence of human society. To assess the potential of land cover features to provide regulating ESs, we used biophysical methods. The maps of land cover potential to provide regulating ES are the result of the analyses. The results indicate that forests are the most important ecosystems that provide ES Local climate regulation and ES Water quality regulation. For ES Biodiversity promotion, the most important ecosystems were natural and seminatural meadows, wetlands, natural and seminatural rivers and water bodies as well as forests. Overall SNR Obedska bara has higher potential to provide all three regulating ESs than PLA Dunajske luhy. These findings point to the importance of natural areas in ensuring the provision of regulating ESs. Properly selected landscape management is the key for maintaining or improving the potential of land cover features to provide regulating ESs. The research can help local authorities in decision making and in creating conservation strategies for selected protected areas.

<p>El crecimiento poblacional y los cambios en el entorno requieren de la disponibilidad de diversidad genética para el desarrollo de sistemas de producción sostenibles, eficientes y competitivos. Esto implica colectar, conservar y conocer los atributos de las poblaciones en mantenimiento de especies de valor actual y taxones relacionados, al igual que entidades biológicas con potencial de desarrollo, lo cual cobra importancia dada la creciente erosión genética. Esto plantea la necesidad de estrategias complementarias de conservación ex situ e in situ, dando prioridad a la variabilidad genética a ser incluida en el proceso, debido a los costos de mantenimiento, y considerar factores no sólo económicos sino también sociales, así como los limitantes actuales para acceder a la diversidad internacional. Este artículo presenta una revisión sobre la importancia de la conservación de los recursos genéticos vegetales, animales y de microorganismos de la agrobiodiversidad, e incluye una discusión y algunos aspectos requeridos para la priorización de taxones y tipo de materiales que se deben incluir en el proceso. Para ello, se parte de la premisa de que la conservación de la diversidad genética sirve para la realización de procesos de valor agregado y de utilización posterior.  </p><p> </p><p><strong>Agrobiodiversity genetic resources conservation for the development of sustainable production systems</strong>  </p><p>Human population growth and environmental changes require the availability of genetic diversity for the development of sustainable, efficient and competitive production systems. This means collection, conservation and characterization of the attributes present in the genetic resources of current important taxa and wild related, and promising species with development potential, which is magnified for a current genetic erosion. It requires complementary ex situ and in situ conservation strategies as well as prioritization of the diversity to be included in the process, due to the conservation costs, considering not only economic values, but also social aspects and the access limitations to genetic resources at international level. The current paper includes a revision related to the importance of the conservation of the plant, animal and microorganisms genetic resources, concerned to agrobiodiversity, with some discussion related to this topic, as well as aspects to be considered for the priorities of species and type of materials to be conserved. For such purpose, the premise is that such diversity, after added-value processes, could be used for the development of sustainable agricultural production systems. </p>

&lt;p&gt;Ecosystems around the world support both biodiversity and human well-being, providing essential goods and services including food, fiber, building materials, moisture/temperature regulation, carbon sequestration, disaster risk reduction, and spiritual/cultural meaning. While we all depend on these benefits to survive and thrive, they are especially critical to the world&amp;#8217;s most vulnerable people. And as populations and economies grow and the climate continues to change, humanity may find itself needing nature&amp;#8217;s benefits in new and unexpected ways.&lt;/p&gt;&lt;p&gt;Mapping ecosystem service provision globally along with biodiversity is essential to effective, just, and lasting conservation planning and prioritization. Identifying global ecosystem service hotspots is key to enabling multi-scale water-energy-land nexus planning for managing socio-economic, climatic, and technological change. This presentation will showcase the latest results of a first-of-its-kind effort to collect the best available spatial datasets of global ecosystem service provision and synthesize them into a common &amp;#8220;critical natural capital&amp;#8221; framework that highlights global ecosystem service &amp;#8220;hotspots&amp;#8221; for both humanity overall and the world&amp;#8217;s most vulnerable people in particular. Drawn from a wide range of observational and modeling studies conducted by physical and social scientists around the world, this innovative synthesis represents the first attempt to create an integrated spatial map of all that we know about humanity&amp;#8217;s dependence on nature, on land and at sea.&lt;/p&gt;&lt;p&gt;Biodiversity is intimately linked to ecosystem services, since intact ecosystems with diverse and abundant native flora and fauna have the greatest ability to provide these irreplaceable services to humanity. Thus, conserving nature for biodiversity and conserving nature for human well-being are two sides of the same coin. This presentation will explore how to integrate these maps of the world&amp;#8217;s critical natural capital into the global conservation conversation. These maps will enable investors and policymakers at the global and national scales to explore the potential consequences to humanity of diverse area-based conservation strategies, providing crucial context for the Post-2020 Global Biodiversity Framework and related conversations.&lt;/p&gt;&lt;p&gt;Sustainable use and management of land and sea, in line with the vision outlined by the Sustainable Development Goals, is essential to preserving both biodiversity and humanity&amp;#8217;s ability to thrive on this planet. The upcoming negotiation of the Post-2020 Global Biodiversity Framework represents a key opportunity to set the planet on a path to more strategic and effective management of the terrestrial and marine realms, and our maps can inform decision-making around the size and spatial distribution of protected areas and other effective conservation measures. Society can only manage what it can monitor, and with the clearer vision of the most important places for both biodiversity conservation and ecosystem service provision these maps provide, humanity will be well-poised to start the next decade off on the right foot.&lt;/p&gt;

Having a reliable ecological reference baseline is pivotal to understanding the current status of benthic assemblages. Ecological awareness of our perception of environmental changes could be better described based on historical data. Otherwise, we meet with the shifting baseline syndrome (SBS). Facing SBS harmful consequences on environmental and cultural heritage, as well as on conservation strategies, requires combining historical data with contemporary biomonitoring. In the present “era of biodiversity”, we advocate for (1) the crucial role of taxonomy as a study of life diversity and (2) the robust, informative value of museum collections as memories of past ecosystem conditions. This scenario requires taxonomist skills to understand community composition and diversity, as well as to determine ecosystem change trends and rates. In this paper, we focus on six Mediterranean benthic habitats to track biological and structural changes that have occurred in the last few decades. We highlight the perception of biological changes when historical records make possible effective comparisons between past reference situations and current data. We conclude that the better we know the past, the more we understand present (and will understand future) ecosystem functioning. Achieving this goal is intrinsically linked to investing in training new taxonomists who are able to assure intergeneration connectivity to transmit cultural and environmental heritage, a key aspect to understanding and managing our changing ecosystems.
