“…Abrupt changes in topography, climate and/ or hydrography can explain sudden latitudinal changes in the composition and abundance of marine biota, e.g. fishes (Ojeda et al 2000, Tolimieri & Levin 2006. A cold-water 'pocket' encompassing northern Portugal (i.e.…”

The Portuguese coast has overlapping distributions of species of both boreal and Lusitanian origins; a large number of cold-and warm-water species have their southern or northern distributional range edges here. A latitudinal gradient in ocean climate, particularly sea surface temperature (SST) and primary production, has been described along this coast. Here, we took advantage of this gradient in ocean climate to explore affinities in the biogenic landscape structure of subtidal shallow reefs (the abundance of habitat patches), as well as in the assemblage structure of macroalgae and associated fishes, between each of 3 regions: Viana do Castelo (41.5°N), Peniche (39.2°N) and Sines (37.8°N). Five reefs were sampled to determine the abundance of biogenic habitats and the assemblage structure of macroalgae and fishes in each region. The structure of the landscape, and of macroalgal and fish assemblages, differed between Viana do Castelo and Peniche and between Viana do Castelo and Sines, but not between Peniche and Sines. Viana do Castelo was the only region with conspicuous kelp forests, while Peniche and Sines were dominated by patches of foliose turf-forming and filamentous algae. Our study revealed an abrupt macroecological change from northern Portugal to central and southern Portugal, suggesting a possible biogeographical reconfiguration and recognition of a wider transitional area from the Atlantic into Mediterranean waters.KEY WORDS: Latitude · Macroecology · Habitat structure · Assemblage structure · Kelps · Fishes · Rocky reefs · Atlantic Ocean Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 466: [9][10][11][12][13][14][15][16][17][18][19] 2012 distribution, abundance and fitness of organisms may be relevant for predicting the effects of climate change, because shifts in distribution patterns along these gradients are among the principal detectable responses to climate change by both aquatic and terrestrial organisms (Southward et al. 1995, Walther et al. 2002, Parmesan & Yohe 2003, Poloczanska et al. 2007, Hawkins et al. 2009, Wernberg et al. 2011b.In the marine realm, biogeographic classifications are a crucial tool for reaching international agreements in marine conservation. Biogeographic units have been defined using sets of hierarchical criteria, within which the biogeographic affinities of biological entities and assemblages are a key component (Lüning 1990, Spalding et al. 2007. Considerable heterogeneity in the composition and abundance of biological communities may exist within any particular biogeographic level, mainly within large spatial units, and so a more detailed classification system is recommended (Spalding et al. 2007, Waters et al. 2010. This is particularly pertinent as shifts in the distributional ranges of several species are occurring in most oceans of the globe as a result of global change (e.g. Southward et al. 1995, Last et al. 2011, Philippart et al. 2011, Wernberg et al. 2012. In this context, it is crucial to tes...

“…These periodical ENinduced faunistic latitudinal fluctuations off northern Chile (18º-20ºS) are directly related to the thermal regime. They lead to a wide and ranging transition zone between the Peruvian and Chilean zoogeographic province, as proposed by Balech (1954), López (1963), Lutjeharms (1990), Parin (1991), Pequeño & Lamilla (1995), Ojeda et al (2000) and Pequeño (2000).…”

“…Pequeño (2000) proposed a different classification, but also related with the before ones, considering a Capricornic Province that includes an Atacaman District and a Central Chilean District, and the Fjord Province including a Chiloé District, and the Fuegian District. Ojeda et al (2000) suggested the existence of only two instead of three fish groups with different association: the tropical and subtropical species, corresponding to the Peruvian Province, and subantarctic species, corresponding to the Magallan Zooprovince. The zone between 30°S and 42°S (central Chile) corresponds to a transition zone inhabited by subantarctic, subtropical, panoceanic and some endemic species as quoted by Mead (1970).…”

El Niño induced changes of the coastal fish fauna off northern Chile and implications for ichthyogeographywere typical for sandy beaches and 14.6% for rocky shores. The shore fish community did not show major changes during and after EN events, as only a few invading species were recorded; just Umbrina xantii was found during all events considered. In order to understand the response of the fish community to ENSO events a biogeographical analyses of 721 fish species reported for neritic habitats (coastal epipelagic and benthic) distributed between 0°-57°S (Gulf of Guayaquil to Cape Horn) was made. Their distribution ranges for normal oceanic conditions were taken from the very numereous existing literature. It is concluded that the north/south migration of Panamic and Peruvian warm water fishes during EN/LN events along the north Chilean coast between 18º-23ºS, indicates that it represents a wide transition zone between the Peruvian and the Chilean ichthyogeographic provinces. Key words: ENSO, neritic fishes, northern Chile, ichthyogeographyResumen.-La franja costera de la zona norte de Chile (18º-23ºS) es habitada por numerosas especies de peces neríticos de las cuales 249 son comúnmente observadas durante condiciones normales y condiciones frías La Niña (LN). Durante El Niño (EN) la ictiofauna del norte de Chile experimenta cambios significativos a causa de la presencia de alrededor de 100 especies de peces invasores que durante periodos normales y/o fríos habitan en latitudes menores, siendo también nombrados "invasores septentrionales" y "peces trópico-ecuatoriales". Este conjunto incluye 15 familias y 86 géneros de peces. Los análisis mostraron que las especies afectadas por los EN no fueron las mismas durante los últimos tres eventos, revelando que solo las especies epipelágicas Anchoa naso, Albula vulpes, Atherinella nocturna y Scomberesox saurus stolatus fueron constantes. Frente al norte de Chile, durante los EN

RESUMENLos peces del género Genypterus son un recurso importante en la industria pesquera, y estos se encuentran expuestos a una serie de ectoparásitos, entre los se encuentran los copépodos los cuales pueden ser muy específicos en sus hospedederos.Una de las especies parásitas corresponde a Sphyriumlaevigatumel cual parasita además tres especies de importancia económica en las pesquerías locales chilenas. Se discuten en el presente trabajo la situación de S. laevigatum en G. blacodes, así como aspectos ecológicos y biogeográficos.Palabras clave: Genypterus blacodes, ectoparásitos, pesquerías. ABSTRACTFishes of Genypterus genus are an important resource in the fishing industry, and these are exposed to a series of ectoparasites, among which ectoparasites are copepods which may be very specific in their hosts. One of the parasitic species corresponds to Sphyriumlaevigatum, which parasites three species of economic importance in Chilean local fisheries. The parasite species of G. blacodes, as well as ecological and biogeographical aspects, are discussed in the present work.
