26-29 October Murcia (Spain) XX Congress of the Iberian Association of Limnology (AIL-2020) III Iberoamerican Congress of Limnology (CIL-2020) XX Congress of the Iberian Association of Limnology (AIL-2020) III Iberoamerican Congress of Limnology (CIL-2020) ONLINE CONGRESS 26-29 October Murcia (Spain) XX Congress of the Iberian Association of Limnology (AIL-2020) III Iberoamerican Congress of Limnology (CIL-2020) Between 26nd and 29th of October 2020 and honouring the theme of the congress, “Limnology in a changing Limnology world”, we will celebrate in a virtual form from Murcia (Southeast of Spain) the XX Congress of the Iberian Association of Limnology (AIL-2020). We highlight that in a the congress is the result of a fruitful coordination between the Iberian Association of Limnology (AIL) and the Iberoamerican Associations of Limnology. changing Thus, this congress is will be also the III Iberoamerican Congress of Limnology (CIL-2020). This event will provide a valuable opportunity, although in a virtual way, for the exchange of knowledge and experiences world among Iberian and Ibero-American limnologists. One of the main aims of this meeting is to discuss the new scientific knowledge that will be useful to improve the management and conservation of inland aquatic ecosystems (from lakes to deltas and estuaries, through rivers and wetlands). This information will be discussed under a global change scenario and considering new models of man-nature cooperation. Under the slogan “Limnology in a changing world”, the congress aims to discuss key issues to manage these ecosystems that despite being of high importance for humans, are subjected to increasing human pressures and impacts. The Iberian Southeast is one of the most arid regions in Europe. Inland aquatic ecosystems in this area acquire a great importance for their uniqueness at European scale. Arid environments offer a wide variety of aquatic ecosystems, hosting an extraordinary biodiversity. The functioning of such ecosystems is determined by extreme biophysic conditions, especially at the terrestrial-aquatic interface. Despite its conservation value, the aquatic ecosystems of this region are highly threatened by the high degree of anthropic alteration and global change. We invite you to participate in this unique event to share experiences, to coordinate works and advance in the knowledge of aquatic ecology, thus contributing to a more sustainable inland aquatic ecosystem management. In this sense, we feel that the involvement of water managers and interested technicians and consultants is essential as a bridge The Congress logo is an original idea between scientific knowledge and society. For this from Antonio José García Cano. reason, our invitation is extended to this collective. 2 PARTNERS Partners & Sponsors SPONSORS 3 President Organizing Mª Rosario Vidal-Abarca Gutiérrez secretary committee Rosa Gómez Cerezo treasurer Mª del Mar Sánchez-Montoya Vocals Mª Luisa Suárez Alonso Josefa Velasco García Andrés Millán Sánchez David Sánchez-Fernández Mercedes Guerrero Brotons Néstor Nicolás Ruiz María Botella Cruz Juana María Mirón Gatón Antonio J.

Grimm Arizona State University, Tempe, Arizona, USA The need for positive thinking in times of crisis: co-producing sustainable future scenarios and nature- based solutions for cities We are in a time of accelerating global crises, and nowhere is this more evident than in cities. Because they concentrate people and infrastructure and are often Invited found along coasts and rivers or in arid areas, cities are particularly vulnerable to the impacts of extreme, weather- related events. Population aggregation provides many benefits to society, including enhanced collective creativity Speakers and economies of scale, but among the detriments is rampant spread of disease, as illustrated by the current coronavirus pandemic. Facing this reality, building resilience for our cities requires diverse strategies that integrate social (S), ecological (E), and technological/built (T) components in a systems (S) approach. It also requires outside-the-box thinking and an emphasis on positive futures. I will present a conceptual framework for SETS integration and an approach for co- creating positive future visions (scenarios) developed and applied in nine North and Latin American cities. Examples from the scenario development process will highlight diverse strategies that address unique challenges across the cities. Closer examination of strategies for flooding will show common approaches across diverse cities. And finally, emergent themes, goals, and strategies will be examined in the context of the pandemic, asking how social, ecological, and technological systems respond and fare under this very different type of threat. 6 Mariana Meerhoff Raquel Mendonça Departamento de Ecología y Gestión Ambiental.

    RisingRising toto thethe ChallengeChallenge Annual Report 2009 From the Executive Director ESA remains financially sound and programmatically strong. n spite of the difficult economic times the country is I facing, ESA remains financially sound and programmatical- ly strong. Our loyal membership stands near 10,000 and the annual meeting—this year in Albuquerque—attracted 3,599 participants with its excellent program offerings. More than 2,000 institutions worldwide subscribe to one or more of our journals, which continue to be among the most highly cited in our field. Ecology, which is 90 years old this year, was named by the Special Libraries Association (SLA) as one of the top 100 most influential journals in science and medicine in the past 100 years. ESA is engaged in a range of activities that are a testament to the breadth of interests of our members. From congressional briefings on “hot” issues to an energized blog; from specialized ESA file photo Credit: conferences and workshops to galvanizing the community behind data sharing; from the continued evo- lution of our prized diversity program to helping faculty use large scale data sets; and from the ever- increasing influence of our journals, ESA continues to be a vibrant and energized society. ESA is also looking to the future. This year, the Governing Board initiated a long range planning process that will examine the existing activities of the Society and anticipate programs and activities that may be needed in the future. We expect that many of our members will be involved in this effort and be asked to help us ensure that ESA stays relevant far into the future.

  • A Genus-Level Supertree of Adephaga (Coleoptera) Rolf G
    ARTICLE IN PRESS Organisms, Diversity & Evolution 7 (2008) 255–269 www.elsevier.de/ode A genus-level supertree of Adephaga (Coleoptera) Rolf G. Beutela,Ã, Ignacio Riberab, Olaf R.P. Bininda-Emondsa aInstitut fu¨r Spezielle Zoologie und Evolutionsbiologie, FSU Jena, Germany bMuseo Nacional de Ciencias Naturales, Madrid, Spain Received 14 October 2005; accepted 17 May 2006 Abstract A supertree for Adephaga was reconstructed based on 43 independent source trees – including cladograms based on Hennigian and numerical cladistic analyses of morphological and molecular data – and on a backbone taxonomy. To overcome problems associated with both the size of the group and the comparative paucity of available information, our analysis was made at the genus level (requiring synonymizing taxa at different levels across the trees) and used Safe Taxonomic Reduction to remove especially poorly known species. The final supertree contained 401 genera, making it the most comprehensive phylogenetic estimate yet published for the group. Interrelationships among the families are well resolved. Gyrinidae constitute the basal sister group, Haliplidae appear as the sister taxon of Geadephaga+ Dytiscoidea, Noteridae are the sister group of the remaining Dytiscoidea, Amphizoidae and Aspidytidae are sister groups, and Hygrobiidae forms a clade with Dytiscidae. Resolution within the species-rich Dytiscidae is generally high, but some relations remain unclear. Trachypachidae are the sister group of Carabidae (including Rhysodidae), in contrast to a proposed sister-group relationship between Trachypachidae and Dytiscoidea. Carabidae are only monophyletic with the inclusion of a non-monophyletic Rhysodidae, but resolution within this megadiverse group is generally low. Non-monophyly of Rhysodidae is extremely unlikely from a morphological point of view, and this group remains the greatest enigma in adephagan systematics.
