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

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

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