Variations of the parasitic infracommunity during the ontogeny of Chromis cyanea (Perciformes: Pomacentridae) in the North coast of Havana, Cuba

, 2015
The infracommunity of parasites of Chromis cyanea (Pisces: Pomacentridae) was studied along the ontogenetic development in the North coast of Havana, Cuba. The objectives were: a- to prove that the core species appears before the strange and stochastic species and they are responsible for the structure in the infracommunity, b- to determine if there is

Metazoan endoparasites of Erythrolamprus poecilogyrus caesius (Cope, 1862) (Serpentes: Dipsadidae) in South American Chaco: Structural attributes at different organization levels.

Acta Herpetologica
In this study, the structure of metazoan endoparasites infracommunities and component community in Erythrolamprus poecilogyrus caesius (Cope, 1862) (Serpentes: Dipsadidae) is presented.

First study on parasites of Hemibrycon surinamensis (Characidae), a host from the eastern Amazon region

Revista Brasileira de Parasitologia Veterinária
This study was the first investigation of communities and infracommunities of parasites of Hemibrycon surinamensis. All the fish collected in a tributary of the Amazon river were parasitized by one or more parasite species. The Brillouin diversity index (

Drivers of fish parasite infracommunities in a high latitude system – a dive into host and parasite traits shaping parasite diversity [PDF]

Understanding the structuring drivers of host-parasite communities is central to predicting how these organisms will respond to environmental changes that are occurring at a rapid rate in northern latitude systems.

Fish population studies using parasites from theSoutheastern Pacific Ocean: Considering host populationchanges and species body size as sources of variabilityof parasite communities

, 2015
Research using parasites infish population studies in the South Eastern Pacific (SEP) is summarized. There are 27 suchstudies (snapshots mainly) in single host species sampled at different geographic localities and at somewhat similar times.They have ...

Are cocoa plantations suitable habitats? Network between parasites (Diptera: Hippoboscidea) and hosts (Mammalia: Chiroptera) in cocoa-dominated landscapes of the Brazilian Amazon

Frontiers in Ecology and Evolution
IntroductionThe relationship between ectoparasitic flies and bats is influenced by anthropogenic changes in natural environments. In the Amazon, various forms of disturbance contribute to ecosystem imbalance, potentially leading to the local extinction ...

Discrimination of fish populations using parasites: Random Forests on a ‘predictable’ host-parasite system

, 2010
SUMMARYWe address the effect of spatial scale and temporal variation on model generality when forming predictive models for fish assignment using a new data mining approach, Random Forests (RF), to variable biological markers (parasite community data ...

La dieta y la fauna de parásitos metazoos del torito Bovichthys chilensis Regan 1914 (Pisces: Bovichthydae) en la costa de Chile centro-sur: variaciones geográficas y ontogenéticas Diet and metazoan parasite fauna of the thornfish Bovichthys chilensis Regan 1914 (Pisces: Bovichthydae) on the coast of central-south Chile: geographical and ontogenetic variations

Revista Chilena de Historia Natural, 2002
Conocer qué, cuánto, cuándo y dónde comen y viven los hospedadores permitiría complementar los estudios parasitarios, ya que la transmisión de los endoparásitos está estrechamente ligada a la dieta, y la de los ectoparásitos al uso del hábitat. Por esto,
