This paper is a panoramic, though incomplete, review of the Peruvian marine biodiversity, including the Peruvian coastal upwelling ecosystem, the marine shallow areas of the Peruvian coast and the mangrove ecosystem of the north of Peru. It includes an analysis of the advances in conservation and management, as well as of research resources. The analysis mainly showed the insufficient human resources and the limited facilities in laboratories and coastal research stations. An analysis was also made from the current unknowns of the research at taxonomy and ecosystem levels, indicating scarce studies for most of the taxonomic groups and biological communities. Finally, the consultations and discussions promoted with the scientific community, allowed the identification of the following issues as the main challenges for future research: formation and training of human resources, development of inventories, studies on endemism and speciation areas, application of new technologies for monitoring physical and biological parameters of the ecosystem, and assessment of the impacts of climate change on marine biodiversity. KEYWORDS: coastal upwelling ecosystem, marine shallow areas, hipoxia, anoxia, Thioploca, mangrove ecosystem of the north, conservation and management. RESUMEN El presente trabajo es una revisión panorámica, aunque incompleta, de la biodiversidad biológica marina del Perú, que incluye el ecosistema de surgencias costeras peruano, las áreas marinas someras de la costa peruana y el ecosistema de manglar del norte del Perú. Incluye un análisis de los avances en conservación y manejo, y de los recursos con que se dispone para la investigación. El análisis mostró principalmente la escasez de recursos humanos y las limitadas facilidades de laboratorios y de estaciones costeras de investigación de que disponen las instituciones. También se hizo un análisis de los vacíos de información a nivel taxonómico y de estudios ecosistémicos, que reflejó una escasez de estudios en la mayoría de grupos taxonómicos y comunidades biológicas. Finalmente, las consultas y discusiones promovidas en el seno de la comunidad científica, permitieron identificar como principales retos para las investigaciones futuras a: la formación y capacitación de recursos humanos, el desarrollo de inventarios taxonómicos, el estudio de endemismos y áreas de especiación, la aplicación de nuevas tecnologías en el monitoreo biótico y abiótico del ecosistema y la evaluación de los impactos del cambio global sobre la biodiversidad marina.
RESUMENLa diversidad launística de la zona intermareal rocosa del departamento de Lima, Perú, lue e en 16 localidades, con énlasis en la dominancia relativa de las especies y su distribución ve registró 175 especies de invertebrados incluidos en 11 Phyla, y con predominio de los molu especies) , crustáceos (44 especies) y poliquetos (30 especies), los tres taxa que caracte bentos marino. Considerando los estudios conocidos, el 41 % del total de las especies está en la comunidad de Perumytilus purpuratus, 34% en Semimytilus algosus y 50% en Phragm moerchi. La diversidad y la zonación es generalizada para la Provincia Peruana.Palabras clave: Invertebrados, diversidad, orilla rocosa, Lima, Perú. ABSTRACTThe launistic diversity 01 the rocky intertidal zone 01 the Department 01 Lima, Perú, was s sixteen localities with emphasis in the relative dominance 01 the species and its vertical dis 175 species 01 invertebrates are registered, predominating the mollusks (79 species), crus (44 species) and polychaete (30 species), the three taxa that predominate in the benthos Considering the communities studied 41 % lor Perumytilus purpuratus are registered, Semimytilus algosus and 50% 01 the species lor Phragmatopoma moerchi. Diversity and zon generalized lor the Peruvian Province.
Se revisa los antecedentes y el estado actual del conocimiento acerca de los moluscos el Perú. Los moluscos marinos y dulceacuícolas se tratan separadamente, y se da informa número de familias, géneros y especies conocidas, su distribución geográfica y estado de ción y utilización por el hombre. Se incluye listas actualizadas de las especies.
This article is concerned with the simulation of pursuit. The article describes one solution for the problem of pursuit of objects moving on a plane by using a mobile robot and an active vision system. The solution deals with the interaction of different control systems using visual feedback and it is accomplished by the implementation of a visual gaze holding process interacting cooperatively with the control of the trajectory of a mobile robot. These two systems are integrated to follow a moving object at constant distance and orientation with respect to the mobile robot. The orientation and the position of the active vision system running a gaze holding process give the feedback signals to the control used to pursuit the target in real-time. The paper addresses the problems of visual fixation, visual smooth pursuit, navigation using visual feedback and compensation for system's movements. The algorithms for visual processing and control are described in the article. The mechanisms of cooperation between the different control and visual algorithms are also described. The final solution is a system able to operate at approximately human walking rates as the experimental results show at the end of the article.
