“…An ontogenetic shift in host diet and/or habitat utilization is a straightforward mechanism that can produce nested patterns of infracommunity structure (e.g. Rohde et al 1998 ;Poulin and Valtonen, 2001). However, the addition of size-dependent parasites (i.e.…”

We examined the patterns of composition and structure of parasite communities in the Mediterranean sparid fish Boops boops along a gradient of fish sizes, using a large sample from a single population. We tested the hypothesis that species forming the core of the bogue parasite fauna (i.e. species which have a wide geographical range and are responsible for recognizable community structure) appear early in the fish ontogeny. The sequential community development observed supported the prediction that core species appear in the fish population earlier than rare and stochastic species. There was also a strong correlation between the order of 'arrival ' of the species and their overall prevalence. Six key species were responsible for recognizable community structure across size/age cohorts ; the addition to this baseline community of key parasite species resulted in a nested structure that is linked to differential species abundance rather than fish size. Information on the life-cycles, distribution and host range of the parasites is used to explain the observed patterns of parasite community structure. We conclude that the small mouth size of B. boops coupled with suction feeding may provide a setting for passive sampling as a mechanism leading to non-random parasite community structure.

“…In recent years, many studies of parasite community ecology, based on nested analyses, have been carried out to understand the forces structuring these communities, especially on fish hosts (e.g. Poulin, 1996Poulin, , 2001Worthen and Rohde, 1996 ;Hugueny and Guégan, 1997 ;Rohde et al 1998 ;Poulin and Guégan, 2000). In parasite communities, a nested subset pattern occurs when the parasite species found in depauperate infracommunities represent non-random subsets of progressively richer ones (Rohde et al, 1998 ;Poulin and Valtonen, 2001).…”

A major goal of community ecology is to identify and explain non-random patterns of species composition. To date, the search for nested patterns in parasite component communities of the same fish host species has not been attempted, despite the fact that this higher hierarchical level is more relevant to nestedness analyses. The aims of this study are first, to determine the structure of component communities -considering ectoparasites and endoparasites separately -of a marine fish (Sebastes capensis) with an extended geographical distribution along the southeastern Pacific and, second, to explain these patterns by taking into account the extrinsic factors associated with the distribution of this host fish. From April to September 2003 and from April to August 2004, 537 fish were captured from different latitudes along the southeastern Pacific. The component communities of both ectoparasites and endoparasites of this fish host showed significant nested subset patterns. However, the type of nestedness pattern differed between ectoparasites and endoparasites. Ectoparasite component communities of S. capensis show higher species richness between latitude 30xS and 40xS, whereas endoparasite component communities show higher species richness between 40xS and 52xS. A nested pattern in ectoparasite component communities of S. capensis result from the gradual loss of some ectoparasites species southward and northward of the central part of their latitudinal distribution, which can be explained by the interaction of S. capensis with other host fish species from the central Chilean coast. Nestedness in endoparasite component communities of S. capensis is produced by the gains and losses of species toward the south of their latitudinal distribution, caused by changes in their prey-items (intermediate hosts) along their latitudinal distributional range.

“…Algunos trabajos previos han indicado la prevalencia como un buen predictor del anidamiento (Rohde et al, 1998;Timi & Poulin, 2003) ya que valores bajos de la misma se relacionan con comunidades azarosas o no estructuradas (Poulin & Guégan, 2000;Poulin & Valtonen, 2002). De hecho, las especies de peces analizadas en este estudio que tuvieron comunidades de parásitos anidadas presentaban al menos una especie parásita con prevalencias sobre el 15% (Anexos 1-2), independiente de la composición de especies parásitas y de la variabilidad de los descriptores numéricos.…”

“…Diversos estudios han demostrado que tanto las condiciones ambientales del entorno como las propias características del hospedero son determinantes en los procesos de colonización y extinción parasitaria. Estos factores pueden llegar a modelar la comunidad de parásitos, dando como resultado patrones con variaciones espacio-temporales en la estructura de la comunidad (Rohde et al, 1998;Zander et al, 1999;Timi & Poulin, 2003;Vidal-Martínez & Poulin, 2003;González & Poulin, 2005;Poulin, 2007).…”

“…Varios estudios han abordado la organización y existencia de estructura en las comunidades de parásitos y los factores que influyen en ella, mediante el uso de modelos basados en patrones nulos, siendo el índice de anidamiento uno de los modelos más empleados (Poulin, 1996(Poulin, , 1998(Poulin, , 2001Rohde et al, 1998;Poulin & Valtonen, 2002;González & Poulin, 2005). Entre las ventajas del uso de los modelos de anidamiento destaca el hecho de que permiten considerar a cada hospedero de la misma especie como hábitats similares en tiempo y espacio (Poulin, 2007), constituyendo una útil herramienta para indagar sobre los posibles factores y mecanismos que pueden estar estructurando la comunidad, al permitir relacionar la organización de la comunidad con características biológicas de los parásitos y los hospederos (Patterson, 1984;Worthen, 1996;McQuaid & Britton, 2013;Aparicio-Rizzo & Muñoz, 2015), así como con factores geográficos y ambientales (Wright et al, 1998;Timi & Poulin, 2003;González & Poulin, 2005).…”

RESUMEN. La estructura comunitaria de parásitos en peces de Chile ha sido poco abordada a través del tiempo y el espacio, impidiendo conocer los patrones de variaciones espacio-temporales. En este trabajo se estudia si la comunidad de endoparásitos de tres peces del intermareal de Chile central difiere entre localidades y años de muestreo, mediante descriptores parasitológicos, composición de especies y anidamiento. Se recolectaron 954 peces de tres especies, Helcogrammoides chilensis, Gobiesox marmoratus y Scartichthys viridis en pozas intermareales ubicadas en lugares cercanos a las bahías de Valparaíso (~32º45'S, 33º30´S) y de Concepción (~36º28'S, 36º41'S), durante 2013 y 2014. Las comunidades parasitarias fueron analizadas y comparadas por especie de hospedero, entre los rangos espaciales (localidades) y temporales (años). Los resultados muestran diferencias no significativas en los descriptores de abundancia, riqueza y diversidad entre localidades en los tres hospederos. Sin embargo, se observaron diferencias de estos descriptores entre años en la Bahía de Valparaíso para H. chilensis y G. marmoratus. La similitud de la composición parasitaria fue baja en cada especie hospedera al comparar entre años y localidades. Las infracomunidades de endoparásitos de S. viridis presentaron un patrón anidado en el tiempo y el espacio, a diferencia de G. marmoratus que presentó un patrón azaroso. En consecuencia, las escalas espacio-temporales son factores influyentes en la estructura de la comunidad de endoparásitos, pero su influencia difiere entre los hospederos. La repetitividad parece estar asociada a la especie de pez y las características agregadas de las comunidades de sus parásitos. Estos resultados indican que otros factores, ambientales y/o ecológicos, pueden influir en su estructura comunitaria.

The parasite community structure in fish species of Chile have scarcely been analysed through time and locations, making it difficult to understand the spatio-temporal variation patterns. In this study, we investigated whether the endoparasitic community of three intertidal fishes in central Chile exhibited spatial or temporal changes. We collected a total of 954 individuals of Helcogrammoides chilensis, Gobiesox marmoratus and Scartichthys viridis in the intertidal rocky zone in localities close to the bays of Valparaíso (~32º45'S, 33º30'S) and of Concepción (~36º28'S, 36º41'S), during in 2013 and 2014. We analized the endoparasite community for each host according to their numerical descriptors, species composition and nestedness, comparing these communities as a function of both space and time. The average richness, abundance and diversity of the parasite infracommunity did not exhibit significant difference between localities (Valparaíso vs ...
