Geographic distribution and composition of the parasite assemblage of the insectivorous bat, Miniopterus natalensis (Chiroptera: Miniopteridae), in South Africa [PDF]

open access: yes, 2012
Includes bibliographical references.All free-living animal species have their own unique parasite assemblages. These parasites can have a significant impact on the fitness and ecology of their hosts, and through them the ecological systems in which they ...

Cytological and molecular description of Hamiltosporidium tvaerminnensis gen. et sp. nov., a microsporidian parasite of Daphnia magna, and establishment of Hamiltosporidium magnivora comb. nov. [PDF]

open access: yes, 2010
We describe the new microsporidium Hamiltosporidium tvaerminnensis gen. et sp. nov. with an emphasis on its ultrastructural characteristics and phylogenetic position as inferred from the sequence data of SSU rDNA, alpha-and beta-tubulin.

Evolutionary and proximate mechanisms shaping host-parasite interactions : the case of "Daphnia magna" and its natural bacterial parasite "Pasteuria ramosa" [PDF]

open access: yes, 2011
Host-parasite interactions are composed of a sequence of steps, all necessary for successful infection: parasites need to encounter their hosts, to enter into their bodies, and to proliferate within them. Selection will act on the mechanisms used in each

Successfully resisting a pathogen is rarely costly in Daphnia magna [PDF]

open access: yes, 2010
Background A central hypothesis in the evolutionary ecology of parasitism is that trade-offs exist between resistance to parasites and other fitness components such as fecundity, growth, survival, and predator avoidance, or resistance to other parasites.

Molecular prevalence, genetic characterization and patterns of Toxoplasma gondii infection in domestic small mammals from Cotonou, Benin

open access: yesParasite, 2022
Toxoplasmosis, one of the most prevalent parasitic infections in humans and animals, is caused by the intracellular protozoan parasite Toxoplasma gondii. Small mammals play a key role as intermediate reservoir hosts in the maintenance of the T.

A transmission model for the ecology of an avian blood parasite in a temperate ecosystem. [PDF]

open access: yesPLoS ONE, 2013
Most of our knowledge about avian haemosporidian parasites comes from the Hawaiian archipelago, where recently introduced Plasmodiumrelictum has contributed to the extinction of many endemic avian species.

Effects of Landscape Spatial Heterogeneity on Host-Parasite Ecology [PDF]

open access: yes, 2015
Landscape spatial heterogeneity interacts with ecological processes that influence pathogen emergence and infectious disease spread. Modification of landscape composition and configuration is hypothesized to alter host densities, frequency of host ...
