Species abundance and asymmetric interaction strength in ecological networks
It is shown that across all types of networks asymmetry was correlated with abundance, so that rare species were asymmetrically affected by their abundant partners, while pairs of interacting abundant species tended to exhibit more symmetric, reciprocally strong effects. Expand
Host specificity in phylogenetic and geographic space.
The multifaceted nature of host specificity is described, the indices available to measure its different facets one at a time or in combination are summarized, and their implications for parasite evolution and disease epidemiology are discussed. Expand
Nestedness versus modularity in ecological networks: two sides of the same coin?
It is found that the correlation between nestedness and modularity for a population of random matrices generated from the real communities decreases significantly in magnitude and sign with increasing connectance independent of the network type. Expand
Phylogenetic Signal in Module Composition and Species Connectivity in Compartmentalized Host-Parasite Networks
It is suggested that the establishment of host-parasite networks results from the interplay between phylogenetic influences acting mostly on hosts and local factors acting on parasites, to create an asymmetrically constrained pattern of geographic variation in modular structure. Expand
Sex-biased parasitism, seasonality and sexual size dimorphism in desert rodents
The results suggest that sex-biased parasitism is a complicated phenomenon that involves several different mechanisms and no relationship was found between sexual size dimorphism and any parasitological parameter in any season. Expand
Functional and Evolutionary Ecology of Fleas: A Model for Ecological Parasitology
This book provides an in-depth case study of a host—parasite system, demonstrating how fleas can be used as a model taxon for testing ecological and evolutionary hypotheses. Expand
Flea species richness and parameters of host body, host geography and host ‘milieu’
The results show that species richness of ectoparasites is affected little by parameters of the host body and to a greater extent by parameters related to the host environment. Expand
Spatial variation in species diversity and composition of flea assemblages in small mammalian hosts: geographical distance or faunal similarity?
Spatial variation in flea diversity among populations of the same mammal species is constrained by the fact that it appears to be a species character, but is also driven by local climatic conditions. Expand
A Tale of Two Phylogenies: Comparative Analyses of Ecological Interactions
The evolution of traits involved in ecological interactions such as predator-prey, host-parasite, and plant-pollinator interactions, are likely to be shaped by the phylogenetic history of bothExpand
