El Centro Poblado de Rio Barranco posee atractivos turísticos que ha generado interés entre los viajeros de diferentes lugares, posee con un gran potencial, que no son aprovechados, razón por la cual no existe ninguna infraestructura de un centro recreacional ecoturístico, servicios adecuados para aquellas personas apasionados al ecoturismo comunitario o de naturaleza, que visitan el lugar, de tal modo que es necesario crear espacios adecuados para que los turistas tengan una experiencia maravillosa, de allí que nace la idea de: “CENTRO RECREACIONAL CON CRITERIOS ECOTURÍSTICOS EN PACAMAYU”. Con el cual, la presente investigación desarrollar objetivos que busca desarrollar el diseño arquitectónico de un centro recreacional con criterios ecoturísticos capaz de proyectar cultura, identidad y sensibilidad, adecuando las características del entorno y valorando la integración d...

Temporal variations at small scale of the coastal marine phytoplankton assemblages were studied. Water samples were collected at a fixed station in Bahia Independencia (Pisco-Peru). The sampling took place in the morning (08:00 h.) and afternoon (15:00 h) over a period of 29 days (March 28 to April 25, 1988). Surface temperatures also were taken, fluctuating from 15,4 °C to 17,2 °C. Diatoms were the principal component of the phytoplankton community and were more related with the total of phytoplankton. Other groups as Dinoflagellates, Coccolitophorids, Silicoflagellates and small flagellates were present but were less important. Skeletonema costatum was the dominant specie during the first nine days of sampling, after that it was substituted by Thalassionema nitzschioides, which remained as dominant until the end of the study. Small variation in species composition but large fluctuati...

Thirty-four samples of mussel assemblages were studied in the rocky mid-littoral zone at 10°45'38"S - 12°57'39"S, in the department of Lima, Peru. Such samples were taken periodically, between June and November, 1972. Using the biological index method, two kinds of communities were determined for the area: community of Perumytilus purpuratus (Lamarck, 1819), in the mid-horizon of the mid-littoral zone and community of Semimytilus algosus (Gould, 1850), in the lower horizon of the mid-littoral zone.

Quantitative monthly samplings, in 2004, were carried out to estimate the density and biomass of Ensis macha (Molina 1782), from Morro Quemado area, Bay Independence, Pisco. The present study analyzes biometric relationships, growth parameters and somatic production using the ELEFAN I routine and the Crisp’s method. During the year 2004 the rate of exploitation (E= 0.69 y-1) was significantly bigger than the values of 2003 and the monthly landings (maximum of 335 t) and fishing effort (maximum of 848 trips) were twice increased. These changes induced in the same year a significant decrease of population mean density (D= 54.13 ind. m-2) and the halfway reduction of somatic production (P= 81.99 gAFDW m-2 y-1) and P/B rate (0.38 y-1) values, regarding the values of the previous year. Also, a significant increment of total mortality rate (2.84 y-1) and the fishing mortality rate (1.97 y-1)...

The incursion of 25 tropical species of mollusks and 15 of crustaceans have been analyzed. This species were registered among the years 1972 and 2003, time in which five El Niño events (EN) were occurred. Presence of the tropical species in the Peruvian Province would be related to larvae transport for benthonic species and juvenile for pelagic species, both stimulated by movements of the masses of waters. It is possible that some species have found «refuge areas» where to be developed and to remain, these species would display a discontinuous distribution in the Peruvian Province, like it is the case of Malea ringens, Prunum curtum and Bulla punctulata. Other species that intrude when typical oceanographic conditions of an event appear EN, apparently disappear when recovering the conditions «No Nino».

The faunistic diversity of the rocky intertidal zone of the Department of Lima, Perú, was studied in sixteen localities with emphasis in the relative dominance of the species and its vertical distribution. 175 species of invertebrates are registered, predominating the mollusks (79 species), crustaceans (44 species) and polychaete (30 species), the three taxa that predominate in the benthos marine. Considering the communities studied 41% for Perumytilus purpuratus are registered, 34% in Semimytilus algosus and 50% of the species for Phragmatopoma moerchi. Diversity and zonation are generalized for the Peruvian Province.

Loligo gahi Orbigny, Patagonian squid, biology was studied in base to samples from artisanal fishery catches between February and March of 1985 in Huarmey, Perú. Characteristics of population structures, reproduction and feeding were analyzed.

The changes of the dominant species features were evaluated in situ, in Lessonia trabeculata subtidal forest during "El Niño 1997-98", tor 14 months, at 3 m depth and the changes in vertical distribution of algae until18 m depth. The high sea temperature values of winter 1997 generated a firsl stress effecl on the species producing in many of them the loss of fronds and easily detachment from the substrate. A second stress effect occurred in summer of 1998, when fronds did not support the high sea temperature values reached, reducing covering in 50%. The tissues of the stipe, upper third, were rot and fall down in March. Both, the stipe length reduced from 150,2 to 31,3 cm and rhizoid diameter from 24,2 to 16,4 cm among February and July, the pressure of herbivorous contributed lo the reduction, and finally the density became worthless in August. The incapacity to regenerate new tissues...

The changes and magnitude of "El Niño" (EN) impact, on larval settlement mechanisms, of some benthic marine invertebrates, on artificial filamentous substrates (nylon fiber) were monthly evaluated, from January 1996 to July 1998, in a 10m depth station located eastern of Independencia Island in Independencia Bay. During 1996, in "La Niña" (LN) warm phase, the number of species showed a peak in April and the density showed one in June, The total density and species number showed a firsl peak in March 1997, then, a second peak in February and July 1998 in the warm phase EN 1997-98, respectively. The bivalve Hiatella solida, turbellaria Notoplana sp., and gastropod Caecum chilense constituted a first group of species that intensified its settlement during cold phase LN 1996. The second group intensified its settlement in earlier warm phase of EN 1997-98, and it was confirmed by the brachi...
