Abstract:
... Ichthyophthirius multifiliis is a ciliated ectoparasite that infects almost all freshwater fishes with low host specificity. However, an endemic fish in the upper Yangtze River, Percocypris pingi, was thought by aqua-culturists to be completely resistant to I. multifiliis. We therefore aimed to determine P. pingi resistance to I. multifiliis. We compared the survival, feed intake, infection intens ...

Abstract:
... Receptor-binding proteins (RBPs) of bacteriophages initiate the infection of their corresponding bacterial host and act as the primary determinant for host specificity. The ever-increasing amount of sequence data enables the development of predictive models for the automated identification of RBP sequences. However, the development of such models is challenged by the inconsistent or missing annota ...

Abstract:
... Bacterial and fungal endophytes form diverse communities and contribute to the performance and health of their host plants. Recent evidence suggests that both host-related factors and environmental conditions determine the community structure of plant endophytes. However, we know little about their distribution patterns and underlying community assembly mechanisms across plant compartments. Here, ...

Abstract:
... Symbiosis with vitamin-provisioning microbes is essential for the nutrition of animals with some specialized feeding habits. While coevolution favors the interdependence between symbiotic partners, their associations are not necessarily stable: Recently acquired symbionts can replace ancestral symbionts. In this study, we demonstrate successful replacement by Francisella-like endosymbionts (-LE), ...

Habitat restoration may depend on the recovery of plant microbial symbionts such as arbuscular mycorrhizal (AM) fungi, but this requires a better understanding of the rules that govern their community assembly. We examined the interactions of soil and host‐associated AM fungal communities between remnant and restored patches of subtropical montane forests. While AM fungal richness did not differ b ...

Abstract:
... Parasites display various degrees of host specificity, reflecting different coevolutionary histories with their hosts. Avian hosts follow multiple migration patterns representing short but also long distances. As parasites infecting migratory birds are subjected to multiple environmental and biotic changes through their flyways, migration may disrupt or strengthen cophylogenetic congruence between ...

Abstract:
... Morphological variability of trematodes from bats (Chiroptera) is poorly studied. Since the variability of adult digenean specimens may be rather high, morphological features are often insufficient for the identification of closely related species, and confirmation with the use of molecular data is required. The aim of our study was to combine the morphological and molecular phylogenetic analyses ...

Host specificity is a fundamental life history trait of symbionts and exists on a broad continuum from symbionts that are specific to one or a few hosts (host specialists), to those associated with multiple different host species (host generalists). However, the biological mechanisms underlying the complexity and wide variation in symbiont host specificity are poorly understood from both the symbi ...
