    • Do Rapoport's rule, the mid-domain effect or the source-sink hypotheses predict bathymetric patterns of ... 
      Moreno, Rodrigo A.; Rivadeneira, Marcelo; Hernández, Cristián; Sampértegui, Sandra; Rozbaczylo, Nicolás (Blackwell Publishing, 2008-05)
      Aim We evaluated the bathymetric gradient of benthic polychaete species richness from the Chilean coast, as well as its possible underlying causes. We tested three possible hypotheses to explain the richness gradient: ...
    • Patterns of endemism in south-eastern Pacific benthic polychaetes of the Chilean coast 
      Moreno, Rodrigo A.; Hernández, Cristián; Rivadeneira, Marcelo; Vidal, Marcela A.; Rozbaczylo, Nicolás (BLACKWELL, 2006-04)
      Aim In this study we evaluate patterns of endemism for benthic polychaete species along the southeastern Pacific coast of Chile. Our goals were (1) to describe latitudinal gradients of endemism and identify areas of high ...
    • Scaling and power-laws in ecological systems 
      Marquet, Pablo A.; Quiñones, Renato A.; Abades, Sebastián R.; Labra, Fabio A.; Tognelli, Marcelo F.; Arim, Matías; Rivadeneira, Marcelo (COMPANY OF BIOLOGISTS LTD, 2005-05)
      Scaling relationships (where body size features as the independent variable) and power-law distributions are commonly reported in ecological systems. In this review we analyze scaling relationships related to energy ...
    • Selective extinction of late Neogene bivalves on the temperate Pacific coast of South America 
      Rivadeneira, Marcelo; Marquet, Pablo A. (PALEONTOLOGICAL SOC INC, 2007)
      We assessed selective extinction patterns in bivalves during a late Neogene mass extinction event observed along the temperate Pacific coast of South America. The analysis of 99 late Neogene and Quaternary fossil sites ...
