Waterbirds and Other Drivers of Endoparasite Communities Across a Hierarchy of Spatial Scales

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Understanding drivers of parasite community structure is compromised by poor sampling and historical focus on one host‐one parasite systems. Yet parasites are ubiquitous and co‐infections are common. This study aimed to identify how various drivers, ranging from landscape scale (waterbird movements, hydrological connectivity, region, host ...

Are cocoa plantations suitable habitats? Network between parasites (Diptera: Hippoboscidea) and hosts (Mammalia: Chiroptera) in cocoa-dominated landscapes of the Brazilian Amazon

Frontiers in Ecology and Evolution
IntroductionThe relationship between ectoparasitic flies and bats is influenced by anthropogenic changes in natural environments. In the Amazon, various forms of disturbance contribute to ecosystem imbalance, potentially leading to the local extinction ...

Helminth infracommunities of the maculated toad Amietophrynus regularis (Anura: Bufonidae) from Ismailia, Egypt [PDF]

Diseases of Aquatic Organisms, 2008
The objective of the present work was to study the helminth infracommunities of Amietophrynus (Bufo) regularis and the possible effects of intrinsic and extrinsic factors on infracommunity structure and on the infection parameters of each parasite species involved. A total of 129 A.

The helminth infracommunities of the wood mouse (Apodemus sylvaticus) two years after the fire in Mediterranean forests [PDF]

Helminthologia, 2013
Abstract Parasites have been recognized as indicators for natural or man-induced environmental stress and perturbation. In this article, we investigated the role of two non-exclusive hypotheses on the response of helminths of wood mice to fire perturbation: 1) a reduction of the helminth infracommunity (species richness) in post-fire ...

Parasite‐Mediated Competition Limits Dominant Cervid Competitor

Ecology Letters, Volume 28, Issue 6, June 2025.
We leveraged 2 years of detection/non‐detection data of moose (Alces alces) and white‐tailed deer (Odocoileus virginianus) and parasite loads in faecal samples within a hierarchical abundance‐mediated interaction model to test hypotheses regarding interactions between these cervids and their shared parasites (Parelaphostrongylus tenuis, Fascioloides ...

Helminth Community of the Black Margate Anisotremus surinamensis (Teleostei: Haemulidae), from Coral Reefs off the Veracruz Coast, Mexico, Southern Gulf of Mexico

Diversity, 2022
We describe the composition and structure of the helminth community of the black margate Anisotremus surinamensis in coral reefs from the Parque Nacional Sistema Arrecifal Veracruzano (PNSAV) off the Veracruz coast.

First study on parasites of Hemibrycon surinamensis (Characidae), a host from the eastern Amazon region

Revista Brasileira de Parasitologia Veterinária
This study was the first investigation of communities and infracommunities of parasites of Hemibrycon surinamensis. All the fish collected in a tributary of the Amazon river were parasitized by one or more parasite species. The Brillouin diversity index (

Role of Multiple Infections on Immunological Variation in Wild Populations

mSystems, 2019
A central challenge in the fields of evolutionary immunology and disease ecology is to understand the causes and consequences of natural variation in host susceptibility to infectious diseases.

First Data on the Helminth Community of the Smallest Living Mammal on Earth, the Etruscan Pygmy Shrew, Suncus etruscus (Savi, 1822) (Eulipotyphla: Soricidae)

Animals, 2021
Suncus etruscus is the smallest living mammal on Earth by mass. Most adults weigh 1.8–3 g with a body length of 35–48 mm. Catching it in small mammal traps in nature is extremely difficult due to its minute size, and therefore special trapping methods ...

Seasonal variation of gastro-intestinal helminths of three bat species in the dry forest of western Mexico

Revista Mexicana de Biodiversidad, 2017
Studies on helminths of chiropterans are relatively uncommon compared to those of other animals, and seasonal changes in helminth load have been rarely examined.
