Quantitative food webs are valuable tools to detect patterns in community structure and
generate hypotheses for experimentation. Quantitative webs of whole communities are …

Reptiles, as well as other vertebrate groups, harbour a significant diversity of parasitic
organisms, from nematodes and other helminths to viruses and bacteria. The Northeast is …

Host-parasite interactions represent a selective force that may reduce hosts' lifespan, their
reproductive success and survival. Environmental conditions can affect host-parasite …

Hosts and parasites interact with each other in a variety of ways, and this diversity of
interactions is reflected in the networks they form. To test for differences in interaction …

In the present study, we aimed to describe the composition of endoparasites associated with
anurans from an altitudinal rainforest enclave in northeastern Brazil. Additionally, we tested …

Abstract Objectives and Design Knowledge of which and how many species are part of an
ecosystem is fundamental to understanding the diversity of organisms, including parasitic …

Life on Earth is supported by an infinite number of interactions among organisms. Species
interactions in these networks are influenced by latitude, evolutionary history and species …

Understanding how parasite communities are assembled, and the factors that influence their
richness, can improve our knowledge of parasite–host interactions and help to predict the …

Changes in the specialization of parasite–host interactions will be influenced by variations in
host species composition. We evaluated this hypothesis by comparing the composition of …

In the present study, we investigated the effect of habitat heterogeneity, elevation gradient,
and phylogenetic distance of host species on the abundance and richness of anuran …
