Ecology, Volume 101, Issue 12, December 2020., 2020 Abstract A core goal of ecology is to understand the abiotic and biotic variables that regulate species distributions and community composition. A major obstacle is that the rules governing species distributions can change with spatial scale. Here, we illustrate this point using data from a spatially nested metacommunity of parasites infecting a ...

Stable Isotopes and Parasites Indicate Feeding Ecology in Florida, USA, Wading Birds
, 2021 We assessed δ13C and δ15N profiles and endoparasite community composition in Great Egrets (Ardea alba), Great Blue Herons (A. herodias), and White Ibis (Eudocimus albus) from four wildlife rescue centers (two mainland, two on islands in the Florida Keys)

High parasite diversity in the amphipod Gammarus lacustris in a subarctic lake
Ecology and Evolution, Volume 10, Issue 21, Page 12385-12394, November 2020., 2020 We set out to identify and quantify the parasite community of Gammarus lacustris to understand the contributions of the amphipod and its parasites to the Takvatn food web. We identified seven parasite taxa: a direct life cycle gregarine, Rotundula sp., and larval stages of two digenean trematode genera, two cestodes, one nematode, and one ...

Journal of Parasitology, 2011 This study analyzed the variation of the parasite infracommunities and their relationship with the diet and spatial distribution of the clingfish Sicyases sanguineus during its ontogeny. In total, 154 clingfish were collected from the intertidal and the upper subtidal zone of Pacific Ocean along the central Chilean coast. A wide range in body length (1.

Infracommunity crowding as an individual measure of interactive-isolationist degree of parasite communities : Disclosing the effects of extrinsic and host factors [PDF]
, 2016 Background: Interactions between parasite species within a host play a fundamental role in shaping parasite communities that have been classified within a continuum between interactive and isolationist.

Food nutrient availability affects epibiont prevalence and richness in natural Daphnia populations
Limnology and Oceanography, Volume 65, Issue 10, Page 2529-2540, October 2020., 2020 Abstract The increased input of nutrients into biological systems has been shown to result in altered biotic interactions through changes in food availability. The aim of this study was to test for an association between phytoplankton nutrient content and epibiont variables in natural zooplankton populations.

Host patch traits have scale‐dependent effects on diversity in a stickleback parasite metacommunity
Ecography, Volume 43, Issue 7, Page 990-1002, July 2020., 2020 Many metacommunities are distributed across habitat patches that are themselves aggregated into groups. Perhaps the clearest example of this nested metacommunity structure comes from multi‐species parasite assemblages, which occupy individual hosts that are aggregated into host populations. At both spatial scales, we expect parasite community diversity

Parasite infracommunity diversity in eels: a reflection of local component community diversity
Parasitology, 2003 The intestinal macroparasite communities of freshwater eels (Anguilla anguilla) captured in the south of England from Windsor (River Thames) during August 2001, and Leckford (River Test) during late June/July 2000, are reported for the first time. Parasite component communities were among the most species rich and diverse recorded from European eels. A

Parasites & Vectors, 2019 Background We assessed metrics of the metazoan parasite infracommunities of the dusky flounder (Syacium papillosum) as indicators of aquatic environmental health of the Yucatan Shelf (YS) prior to oil extraction.
