Global patterns of modularity and narrow host use in fish-parasitic copepods (Crustacea) [PDF]

open access: yesBiodiversity Data Journal
Parasitic copepods are amongst the most diverse and ecologically significant parasites of fish, yet their macroecological patterns remain poorly understood. In this study, a comprehensive dataset of fish–copepod associations was obtained and curated from

Promiscuous specialists: Host specificity patterns among generalist louse flies.

open access: yesPLoS ONE, 2021
Ectoparasites such as louse flies (Diptera: Hippoboscidae) have tendency for host specialization, which is driven by adaptation to host biology as well as competition avoidance between parasites of the same host.

Morphological and molecular studies of the nematode parasite Heterakis gallinarum (Heterakidae) infecting the cattle egret Bubulcus ibis (Ardeidae) [PDF]

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2023
Parasites infecting migratory birds all over the world are still under investigation. The identification of parasitic taxa infecting ardeids was done concerning their morphological and morphometric features.

A meta-analysis of host specificity in Neotropical hard ticks (Acari: Ixodidae) [PDF]

open access: yes, 2013
Host specificity of Neotropical hard ticks (Acari: Ixodidae) was analyzed by using the number of hosts species for each tick species and the index of host specificity STD*, which integrates phylogenetic and ecological information. The analyses were based

Extensive remodeling of the Pseudomonas syringae pv. avellanae type III secretome associated with two independent host shifts onto hazelnut

open access: yesBMC Microbiology, 2012
Background Hazelnut (Corylus avellana) decline disease in Greece and Italy is caused by the convergent evolution of two distantly related lineages of Pseudomonas syringae pv. avellanae (Pav). We sequenced the genomes of three Pav isolates to determine if

Bacterial leaf symbiosis in angiosperms: host specificity without co-speciation. [PDF]

open access: yesPLoS ONE, 2011
Bacterial leaf symbiosis is a unique and intimate interaction between bacteria and flowering plants, in which endosymbionts are organized in specialized leaf structures.

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

Female-induced increase of host-plant volatiles enhance specific attraction of aphid male Dysaphis plantaginea (Homoptera: Aphididae) to the sex pheromone [PDF]

open access: yes, 2009
All aphid species studied so far share the same sex pheromone components, nepetalactol and nepetalactone. Variation by different enantiomers and blends of the two components released by different aphid species are limited and can only partially explain ...

Resolving the infection process reveals striking differences in the contribution of environment, genetics and phylogeny to host-parasite interactions [PDF]

open access: yes, 2011
Background Infection processes consist of a sequence of steps, each critical for the interaction between host and parasite. Studies of host-parasite interactions rarely take into account the fact that different steps might be influenced by different ...

Host Specificity and Characteristics of Viscum ovalifolium in Pulau Dua Mangrove, Banten, Indonesia

open access: yesHayati Journal of Biosciences, 2012
The prevalence of V.ovalifolium in Pulau Dua Nature Reserve was surveyed. This parasite was observed parasitizing on only two host species, Excoecaria agallocha and Thespesia populnea, among 11 potential host tree species in the study area.
