- Biodiversity patterns of cavernicolous ground-beetles and their conservation status in the Azores, with the description of a new species: Trechus isabelae n. sp (Coleoptera : Carabidae : Trechinae)Publication . Borges, Paulo A. V.; Oromí, Pedro; Serrano, Artur R. M.; Amorim, Isabel R.; Pereira, Fernando E. A.Diversity patterns of cave and epigean Trechinae (Coleoptera, Carabidae) from the Azores (Portugal) are reported based on recently standardized sampling protocols in different habitats of this geologically young and isolated volcanic archipelago. A total of 10 species are studied, including Trechus isabelae n. sp., collected in a volcanic pit on São Jorge, one of the nine islands of the Azores. This new Trechus species represents the eighth species of Trechinae described from the underground environment of the Azores. An identification key for the Azorean species of Trechus is provided along with additional information per species on their distribution and conservation status in the archipelago. Possible reasons for the different degrees of adaptation to the conditions of the underground environment exhibited by Trechinae are also discussed.
- Bugs and Society I : Raising Awareness About Endemic BiodiversityPublication . Arroz, Ana Margarida Moura; Gabriel, Rosalina; Amorim, Isabel R.; Marcos, Rita S.; Borges, Paulo A. V.The negative impact of biodiversity loss on ecosystem functioning and services, and ultimately on human well-being, has been unequivocally established; however, despite all efforts, biodiversity is still declining worldwide. It is widely accepted that biodiversity awareness is crucial for its conservation. Nevertheless, after many initiatives to alert society about the consequences of losing biodiversity, biodiversity loss is still perceived as a minor environmental risk compared to others such as climate change. Thus far, most communication strategies have involved conventional venues, targeting people who are already “environmentally-aware”, and have not incorporated societal idiosyncrasies and cultural backgrounds. The wicked problem of loss of biodiversity and the existing strategies to promote people’s engagement are discussed under the risk communication framework. The risk perspective focuses science communication on the mitigation of risk and/or the minimisation of its consequences. Further, it helps to keep the target in mind, to establish activities and strategies that are useful for reaching the proposed goals, and to regulate the processes based on desired outcomes. After presenting the role of communication in risk governance, the principles and strategic options of the Azorean intervention, Bugs & Society, are presented. This communicational programme will be analysed and evaluated in another chapter through the presentation of two activities, which are provided as examples for further discussion.
- Bugs and Society II : Testing Two Communication Strategies for Public Engagement in the AzoresPublication . Amorim, Isabel R.; Arroz, Ana Margarida Moura; Marcos, Rita S.; Borges, Paulo A. V.; Gabriel, RosalinaTwo initiatives to raise biodiversity awareness towards Azorean endemic species, an outdoor exhibition Açorianos há milhões de anos (Azoreans for millions of years) and a web contest to name insects Chama-lhe Nomes! (Pick a Name!), are presented in this chapter. Both communicational strategies targeted non-traditional audiences, relied on the Portuguese and Azorean cultural identity and on anthropic verisimilitude of situations involving insects. The context, principles, assumptions and multidisciplinary approach involved in the development of the public awareness activities were presented in detail in chapter “Bugs and Society I: Raising Awareness About Endemic Biodiversity”. Apart from having symbolically occupied the urban public domain, the outdoor exhibition triggered positive reactions in more than three-quarters of the observers, prompting them to seek more information about the insects, to want to see them alive, to photograph them, etc. On the other hand, the web contest attributed common names to 12 endemic species of insects and motivated over one hundred people to carefully consider their photos and descriptions, engaging in sheer naturalistic pleasure. Less favourable were the post-observation recognition indicators of urban exposure, since only less than one-third of the interviewees correctly identified the insect’ group represented on the banner or could place the origin of the animal. Nevertheless, the means assigned to the evaluation of the intervention were not enough to undertake a full assessment of the impacts produced in the knowledge, attitudes and behaviours of viewers and users. Still, the resonance in the media was considerable, in terms of the number of news stories and the diversity of vehicles and audiences reached at regional (outdoor exhibition) and national levels (web contest). Communication devices like the ones presented are expected to raise biodiversity awareness and empower people regarding its preservation in the Azores. Moreover, the critical analysis of these initiatives is expected to provide guidelines that maximise the transferability of communication strategies to other social settings.

This rich biodiversity is under threat from anthropogenic drivers, such as climate change, invasive species, land use changes, overexploitation, or pathogen (re)emergence. The inventory, characterisation, and study of biodiversity at inter- and intra-specific levels using genomics is crucial to promote its preservation and recovery by informing biodiversity conservation policies, management measures, and research. The participation of researchers from Portuguese institutions in the European Reference Genome Atlas (ERGA) initiative and its pilot effort to generate reference genomes for European biodiversity has reinforced the establishment of Biogenome Portugal. This nascent institutional network will connect the national community of researchers in genomics. Here, we describe the Portuguese contribution to ERGA’s pilot effort, which will generate high-quality reference genomes of six species from Portugal that are endemic, iconic, and/or endangered and include plants, insects, and vertebrates (fish, birds, and mammals) from mainland Portugal or the Azores islands. In addition, we outline the objectives of Biogenome Portugal, which aims to (i) promote scientific collaboration, (ii) contribute to advanced training, (iii) stimulate the participation of institutions and researchers based in Portugal in international biodiversity genomics initiatives, and (iv) contribute to the transfer of knowledge to stakeholders and engaging the public to preserve biodiversity. This initiative will strengthen biodiversity genomics research in Portugal and fuel the genomic inventory of Portuguese eukaryotic species. Such efforts will be critical to the conservation of the country’s rich biodiversity and will contribute to ERGA’s goal of generating reference genomes for European species.
- Cave microbial community composition in oceanic islands : disentangling the effect of different colored mats in diversity patterns of Azorean lava cavesPublication . Riquelme, Cristina; Rigal, François; Hathaway, Jennifer J. Marshall; Northup, Diana E.; Spilde, Michael N.; Borges, Paulo A. V.; Gabriel, Rosalina; Amorim, Isabel R.; Dapkevicius, Maria de Lurdes N. E.Processes determining diversity and composition of bacterial communities in island volcanic caves are still poorly understood. Here, we characterized colored microbial mats in 14 volcanic caves from two oceanic islands of the Azores using 16S rRNA gene sequences. Factors determining community diversity (α) and composition (β) were explored, namely colored mats, caves and islands, as well as environmental and chemical characteristics of caves. Additive partitioning of diversity using OTU occurrence showed a greater influence of β-diversity between islands and caves that may relate to differences in rare OTUs (singletons and doubletons) across scales. In contrast, Shannon diversity partitioning revealed the importance of the lowest hierarchical level (α diversity, colored mat), suggesting a dominance of cosmopolitan OTUs (>1%) in most samples. Cosmopolitan OTUs included members involved in nitrogen cycling, supporting the importance of this process in Azorean caves. Environmental and chemical conditions in caves did not show any significant relationship to OTU diversity and composition. The absence of clear differences between mat colors and across scales may be explained by (1) the geological youth of the cave system (cave communities have not had enough time to diverge) or/and (2) community convergence, as the result of selection pressure in extreme environments.

- Children’s preferences for less diverse greenspaces do not disprove biophiliaPublication . Fattorini, Simone; Gabriel, Rosalina; Arroz, Ana Margarida Moura; Amorim, Isabel R.; Borges, Paulo A. V.; Cafaro, PhilipExposure to and connection with nature is increasingly recognized as providing significant well-being benefits for adults and children. Increasing numbers of children growing up in urban areas need access to nature to experience these benefits and develop a nature connection. Under the biophilia hypothesis, children should innately affiliate to nature.
- Comparative phylogeography of endemic Azorean arthropodsPublication . Parmakelis, Aristeidis; Rigal, François; Mourikis, Thanos; Balanika, Katerina; Terzopoulou, Sofia; Rego, Carla; Amorim, Isabel R.; Crespo, Luís C.; Pereira, Fernando E. A.; Triantis, Kostas A.; Whittaker, Robert J.; Borges, Paulo A. V.BACKGROUND: For a remote oceanic archipelago of up to 8 Myr age, the Azores have a comparatively low level of endemism. We present an analysis of phylogeographic patterns of endemic Azorean island arthropods aimed at testing patterns of diversification in relation to the ontogeny of the archipelago, in order to distinguish between alternative models of evolutionary dynamics on islands. We collected individuals of six species (representing Araneae, Hemiptera and Coleoptera) from 16 forest fragments from 7 islands. Using three mtDNA markers, we analysed the distribution of genetic diversity within and between islands, inferred the differentiation time-frames and investigated the inter-island migration routes and colonization patterns. RESULTS: Each species exhibited very low levels of mtDNA divergence, both within and between islands. The two oldest islands were not strongly involved in the diffusion of genetic diversity within the archipelago. The most haplotype-rich islands varied according to species but the younger, central islands contributed the most to haplotype diversity. Colonization events both in concordance with and in contradiction to an inter-island progression rule were inferred, while a non-intuitive pattern of colonization from western to eastern islands was also inferred. CONCLUSIONS: The geological development of the Azores has followed a less tidy progression compared to classic hotspot archipelagos, and this is reflected in our findings. The study species appear to have been differentiating within the Azores for <2 Myr, a fraction of the apparent life span of the archipelago, which may indicate that extinction events linked to active volcanism have played an important role. Assuming that after each extinction event, colonization was initiated from a nearby island hosting derived haplotypes, the apparent age of species diversification in the archipelago would be moved closer to the present after each extinction-recolonization cycle. Exploiting these ideas, we propose a general model for future testing.
- Comparison of Bacterial Diversity in Azorean and Hawai'ian Lava Cave Microbial MatsPublication . Hathaway, Jennifer J. Marshall; Garcia, Matthew G.; Balasch, Monica Moya; Spilde, Michael N.; Stone, Fred D.; Dapkevicius, Maria de Lurdes N. E.; Amorim, Isabel R.; Gabriel, Rosalina; Borges, Paulo A. V.; Northup, Diana E.Worldwide, lava caves host colorful microbial mats. However, little is known about the diversity of these microorganisms, or what role they may play in the subsurface ecosystem. White and yellow microbial mats were collected from four lava caves each on the Azorean island of Terceira and the Big Island of Hawai’i, to compare the bacterial diversity found in lava caves from two widely separated archipelagos in two different oceans at different latitudes. Scanning electron microscopy of mat samples showed striking similarities between Terceira and Hawai’ian microbial morphologies. 16S rRNA gene clone libraries were constructed to determine the diversity within these lava caves. Fifteen bacterial phyla were found across the samples, with more Actinobacteria clones in Hawai’ian communities and greater numbers of Acidobacteria clones in Terceira communities. Bacterial diversity in the subsurface was correlated with a set of factors. Geographical location was the major contributor to differences in community composition (at the OTU level), together with differences in the amounts of organic carbon, nitrogen and copper available in the lava rock that forms the cave. These results reveal, for the first time, the similarity among the extensive bacterial diversity found in lava caves in two geographically separate locations and contribute to the current debate on the nature of microbial biogeography.
