Over the years the geographical breadth of ICSU activities has changed. Increasingly a major emphasis for ICSU has been the development of scientific capacity in developing countries and the integra- tion of these scientists in international research initiatives. The creation of three ICSU Regional Offices, established in Africa, Asia and the Pa- ci fic, and Latin America and the Caribbean also marks a fundamental change in ICSU struc ture, the aim of which is two-fold. First, it should enhance the participation of scien- tists and regional organizations from developing countries in the programs and activities of the ICSU community. Secondly, it will allow ICSU to play a more active role in strength- ening science within the context of regional priorities through scientific collaboration. Especially in regard to Latin America and the Caribbean, this is an important step in bridging the ‘islands of competence’ that exist in every country and that together will be able ato advance significantly the scientific research agenda in the region. The first step towards the establishment of a Regional Office was the appointment in 2006 of the Re gional Committee for Latin America and the Caribbean, composed of renowned scientists of the region. The Regional Office for Latin America and the Caribbean was the third to be established and was inaugurated in April 2007. It is hosted by the Brazilian Academy of Sci ences, in Rio de Janeiro, Brazil, and supported by the Brazilian Ministry of Science and Technology, ICSU, and CONACYT Mexico. From October 2010 it will 3 be hosted by the Mexican Academy of Science, with the support of CONACYT Mexico. Based on the ICSU Strategic Plan 2006-2011, the Regional Committee has select- ed four priority areas to be developed: • Mathematics Education; • Biodiversity: knowledge, preservation and utilization of biodiversity of all countries of the Latin American and Caribbean region, and to ensure that the scientific com- munity of the smaller countries of the region are fully integrated in DIVERSITAS; • Natural Hazards and Disasters: prevention and mitigation of risks especially of hydrometeorologic origin with special attention to the necessary social science research; • Sustainable Energy: assessment of the existing capacities in the LAC region and the social impact of the use and development of new energy resources. Four Scientific Planning Groups were appointed to develop proposals that reviewed the current status of the priority area in the region and to formulate a set of detailed objectives and targeted areas of research to be developed in the next few years. Engaging highly qualified scientists from Latin America and the Caribbean, the Scientific Planning Groups did outstanding work within a restricted time limit. We thank each and every one of the participants for their enthusiasm and dedication. This document is the final report of the Scientific Planning Group in Biodiversity, which is being submitted to the scientific community in the expectation of effectively influencing the development of scientific research in this area in the years to come.

It comprises the living component of the Life Supporting System of our planet and is the source of numerous and vital ecosystem services. The loss of biodiversity constitutes a critical problem for human existence to the extent that biodiversity science is amply recognized as a priority area of scientific research in both the developed and developing world. Biodiversity science spans a wide range of basic scientific disciplines ranging from molecular genetics through to systematics, population through to ecosystem ecology and macroecology, as well as integrative research areas such as conser- vation biology, biocultural conservation, impacts of climate change, complex sys- tems, ecological economics and environmental ethics. The aims of this document are to: a] provide a snap-shot assessment of the state of knowledge of biodiversity in Latin America and the Caribbean (LAC), so as to situate the region’s biodiversity on the global stage; b] critically assess biodiver- sity research undertaken in the region so as to identify knowledge gaps and needs; c] assess institutional capacity for biodiversity science in the region and identify the main biodiversity research centers; and, d] arrive at a set of priority research themes and identify capacity, infrastructure and other needs for implementing the ICSU-LAC biodiversity science plan. For the purposes of this study, LAC is understood as all nations and dependen- cies in or immediately off the coasts of Mexico, Central and South America, as well as those in the Caribbean Sea. 5 The first section of the assessment is devoted to setting the context under which LAC´s biodiversity developed. Palaeogeographic evolution of the region over more that 100 Ma precipitated increasing compartmentalization of the LAC region result- ing in a marked increase in biome and habitat diversity throughout the Cretaceous, Tertiary and Quaternary, while the arrival of humans as of 14 500 BP, was paral- leled by intensive cultural diversification and mostly non-intensive land use. Up until pre-Columbian times, the physiographic evolution of the region together with the outstanding cultural diversification of the Amerindians, reflected in hundreds of lan- guages, generally favored the accumulation of biodiversity and related cultural knowledge. A reverse trend was set into motion in post-Columbian time, culminat- ing in today’s large-scale agriculture, plantation forestry and increasing urbaniza- tion. The projected urban population in the year 2050 exceeds the entire popula- tion of LAC today, with loss of traditional knowledge to be expected. The assessment’s second section shows that LAC monopolizes the Planet’s bio- diversity through a detailed overview of: diversity of biogeographical divisions, diversity of ecosystems, diversity of species, diversity of life forms and functional groups, concentration of endemic organisms, agro-biodiversity associated with cultural diversity, Biodiversity Hotspots and Frontier Forests, and diversity of biotic interactions. Some highlights are: six countries of LAC fall into the Megadiverse league; 32% of global biodiversity in vascular plants, summing to an estimated 95 000, for a land area constituting 9.6% of total land area worldwide; in South America: 33% of global biodiversity in birds, 32% of anurans, 25% of mammals and 20% of reptiles; two Vavilovian Centers of Origin of Agriculture and Plant Domestication; seven of the 25 Biodiversity Hotspots for Conservation Priority; a recently-discovered Hotspot for bryophytes at the extreme southern end of South America; 22% of global Frontier Forest. Brazil, the largest country in LAC, has an estimated 170-210 thousand described species considering all taxonomic groups, but is believed to have around 1.8 million in total, taking into account microor- ganisms and fungi. 6 BIODIVERSITY IN LATIN AMERICA AND THE CARIBBEAN Knowledge emerging from molecular phylogenetics, genome sequencing, the study of the ecosystem services of biodiversity, and the exploration of unusual bio- diversity and habitats, is also reviewed, where the South American Andes have recently revealed some of the highest speciation rates in the world. It is concluded that major knowledge lacunae are still evident in many groups of organisms/coun- tries,

One clearly defined diversification was from temperate ancestors into tropical habitats. The focus of this work was to explore leaf and stem anatomical traits in relation to habitat (temperate and tropical) and elevation of the native range. A closely-related group of Rhododendron was selected to reduce variation in genetic history and reveal environment–associated adaptive traits. Vessel anatomical traits of Rhododendron accessions were assayed for the trade of between safety (protection against catastrophic failure) and efficiency (high theoretical conductivity). Rhododendron wood and vessels were found to be relatively safe. The metrics of wood efficiency were higher for the tropical species. Thus, a trade-off between safety and efficiency was found although the wood of Rhododendron is characterized as highly safe. Leaf anatomical traits of Rhododendron were assayed for habitat and elevation. Leaves on tropical species were thicker and denser compared with temperate species. Idioblasts were always found in tropical leaves but not in temperate species.

Recibido 6 de diciembre, 2010; aceptado 30 de junio, 2011 Abstract DNA barcoding has been proposed as a practical and standardized tool for species identification. However, the determination of the appropriate marker DNA regions is still a major challenge. In this study, we eXtracted DNA from 27 plant species belonging to 27 different families native of Costa Rica, amplified and sequenced the plastid genes matK and rpoC1 and the intergenic spacer trnH-psbA. Bioinformatic analyses were performed with the aim of determining the utility of these markers as possible barcodes to discriminate among species and for phylogenetic reconstruction. From the markers selected, the trnH-psbA spacer was the most variable in terms of genetic distance and the most promising region for barcoding. However, it presented a limited use for constructing phylogenies due to the compleXity of its alignment. The locus matK was less variable but was also useful for species discrimination and for phylogenetic tree generation. The rpoC1 region was highly conserved and suitable for phylogenetic studies, but presented a limited utility as a barcode. The marker combination matK and rpoC1 provided the best resolution for establishing valid phylogenetic relationships among the analyzed plant families.

    UNIVERSITÀ DEGLI STUDI DI PADOVA Department of Land, Environment Agriculture and Forestry Second Cycle Degree (MSc) in Forest Science Recommendation of native species for the reforestation of degraded land using live staking in Antioquia and Caldas’ Departments (Colombia) Supervisor Prof. Lorenzo Marini Co-supervisor Prof. Jaime Polanía Vorenberg Submitted by Alicia Pardo Moy Student N. 1218558 2019/2020 Summary Although Colombia is one of the countries with the greatest biodiversity in the world, it has many degraded areas due to agricultural and mining practices that have been carried out in recent decades. The high Andean forests are especially vulnerable to this type of soil erosion. The corporate purpose of ‘Reforestadora El Guásimo S.A.S.’ is to use wood from its plantations, but it also follows the parameters of the Forest Stewardship Council (FSC). For this reason, it carries out reforestation activities and programs and, very particularly, it is interested in carrying out ecological restoration processes in some critical sites. The study area is located between 2000 and 2750 masl and is considered a low Andean humid forest (bmh-MB). The average annual precipitation rate is 2057 mm and the average temperature is around 11 ºC. The soil has a sandy loam texture with low pH, which limits the amount of nutrients it can absorb. FAO (2014) suggests that around 10 genera are enough for a proper restoration. After a bibliographic revision, the genera chosen were Alchornea, Billia, Ficus, Inga, Meriania, Miconia, Ocotea, Protium, Prunus, Psidium, Symplocos, Tibouchina, and Weinmannia. Two inventories from 2013 and 2019, helped to determine different biodiversity indexes to check the survival of different species and to suggest the adequate characteristics of the individuals for a successful vegetative stakes reforestation.

    Gayana Bot. 69(1): 9-29, 2012 ISSN 0016-5301 Actualización sistemática y distribución geográfica de Mutisioideae (Asteraceae) de Chile Systematic revision and geographic distribution of Chilean Mutisioideae (Asteraceae) ANDRÉS MOREIRA-MUÑOZ1, VANEZZA MORALES1 & MÉLICA MUÑOZ-SCHICK2 1Instituto de Geografía, Pontificia Universidad Católica de Chile, Vicuña Mackenna 4860, Macul, Santiago, Chile. 2Museo Nacional de Historia Natural, Casilla 787, Santiago, Chile. [email protected]; [email protected]; [email protected] RESUMEN Se presenta una actualización sistemática y de distribución geográfica de las especies y categorías infraespecíficas de la subfamilia Mutisioideae (tribus Mutisieae, Nassauvieae y Onoserideae) para Chile. El trabajo fue realizado sobre la base de bibliografía y la revisión de ejemplares principalmente de los herbarios SGO y CONC. Los resultados arrojan la presencia de 28 géneros, 192 especies y otros 22 taxones infraespecíficos en Chile. Siete de estos géneros, 77 especies y 12 taxones infraespecíficos tienen carácter de endémicos para el país. La revisión arroja dos adiciones y dos sustracciones a la flora de Chile. Adicionalmente, 47 de los taxones han sido corregidos en cuanto a su distribución geográfica por región en Chile. Se discute finalmente las implicancias que posee un adecuado conocimiento de la distribución geográfica de las especies para estudios de biogeografía y conservación de la flora nativa. PALABRAS CLAVE: Asteraceae, Chile, Compositae, diversidad, endemismo, Mutisieae, Nassauvieae, Onoserideae. ABSTRACT A systematic revision including the geographic distribution of the taxa pertaining to the Chilean Mutisioideae (tribes Mutisieae, Nassauvieae and Onoserideae) has been undertaken. The study has been done by means of the revision of available monographs and the most recent regional checklist, together with the examination of exemplars from SGO and CONC herbaria.
