CP. 11600, Montevideo, Uruguay. *[email protected] RESUMEN Se determinaron número cromosómico, cariotipo, patrones de bandeo, localización de genes ribosómicos y contenido de ADN nuclear, en dos poblaciones de Brasiliopuntia schulzii (Cactaceae, subfam. Opuntioideae). La especie resultó diploide (2n=22), presentó una fórmula cariotípica de 10 m + 1 sm. El bandeo cromosómico CMA/DAPI reveló la presencia de un par cromosómico con una banda CMA+/DAPI- asociada a NORs. Con la técnica de FISH se observó que los loci 18- 5,8-26S fueron consistentes con los bloques CMA+/DAPI-/NORs. La señal para el gen 5S se localizó en el cuarto par m en una región telomérica. En las dos poblaciones el análisis de contenido de ADN reveló una mezcla de núcleos con tres picos de 2C, 4C y 8C. Esto indicaría un proceso de endopoliploidía en la especie. Los resultados reportados en este trabajo, combinados con las características morfológicas, indicarían que este género posee caracteres basales, concordando con los análisis filogenéticos de la subfamilia. PALABRAS CLAVE: Brasiliopuntia, cariotipo, contenido de ADN, endopoliploidía, heterocromatina, genes ribosomales.

  • Biodiversity Summary for NRM Regions Species List
    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations.
