Antagonistic interactions between hosts and parasites are key structuring forces in natural populations. Demographic factors like extinction, migration and the effective population size shape host-parasite metapopulational dynamics. Therefore, to understand the evolution of host-parasite systems it is necessary to study the distribution of the genetic ...

ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

Epidemiological studies on Fasciola hepatica in Gafsa oases (South West of Tunisia)
Epidemiological investigations on Fasciola hepatica fasciolasis were carried out from July 2004 to June 2005 in the Gafsa oases (Tunisia) after the detection of a human case. Three habitats were studied: one in El Gsar and two in Ain Soltan.

ABSTRACT Microbiota have emerged as fundamental regulators of host physiology, shaping both ecological interactions and evolutionary trajectories. Yet, the determinants of microbiota diversity and structure in wild populations—particularly the respective roles of host genetics and environmental context—are still poorly understood.

Paramphistomum daubneyi: characteristics of infection in three lymnaeid species
Experimental infections of two South American lymnaeids (Lymnaea neotropica and L. viatrix var. ventricosa) with Paramphistomum daubneyi were carried out to determine if these snail species could sustain larval development of this digenean and, if so, to

We report a preliminary analysis on the relationships between drainage basin structure and genetic structure of populations of the European vector of fasciolosis, Galba truncatula. In the study area, 251 snails belonging to 12 populations were collected along different ditches of a same river network.

ABSTRACT The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

ABSTRACT Only one last interglacial relative sea‐level indicator point (SLIP) has been recognised for Fenland, eastern England, and the nearest penultimate interglacial SLIP is located on the north Norfolk coast. Such limited information restricts the regional input to, and hence the relevance of, global reconstructions of late Middle and Late ...
