Host life-history variation in response to parasitism
Over half of all living species of plants and animals are parasitic, which by definition involves intimate association with and unfavourable impact on hosts (Price, 1980). This paper will onlyExpand

Revealing the secret lives of cryptic species: Examining the phylogenetic relationships of echinostome parasites in North America.
The recognition of cryptic parasite species has implications for evolutionary and population-based studies of wildlife and human disease. Echinostome trematodes are a widely distributed, species-richExpand

A Cost of Increased Early Reproductive Effort in the Snail Biomphalaria glabrata
The portion of an organism's energy budget that is allocated to reproduction at each age is selected to maximize overall lifetime reproductive success. Thus reproductive effort at each age should beExpand

Snail-trematode life history interactions: past trends and future directions.
Life history traits expressed by organisms vary due to ecological and evolutionary constraints imposed by their current environmental conditions and genetic heritage. Trematodes often alter the lifeExpand

Intraspecific variation in the rDNA its loci of 37-collar-spined echinostomes from North America: implications for sequence-based diagnoses and phylogenetics.
The recent finding of the 37-collar-spined Echinostoma revolutum in North America prompted rDNA nucleotide sequence comparisons between this worm and the sympatric Echinostoma trivolvis. ThreeExpand

Revealing Cryptic Parasite Diversity in a Definitive Host: Echinostomes in Muskrats
Abstract:  Many trematode groups have a long history of systematic revision, which can make parasite identification a difficult task. The trematode parasites of muskrats are no exception. Here, weExpand

A comparison of microsatellite polymorphism and heterozygosity among field and laboratory populations of Schistosoma mansoni.
The genetic diversity of a field population (recently collected in Melquiades, Brazil) and two laboratory strains (LE and NMRI) of a human blood fluke, Schistosoma mansoni, were analysed usingExpand

Genetic diversity and population structuring of Schistosoma mansoni in a Brazilian village.
The digenean trematode Schistosoma mansoni is responsible for chronic schistosomiasis worldwide, and in Brazil alone an estimated 35 million people are at risk. To evaluate epidemiological patternsExpand

Possible male coalitions in a solitary mongoose
Abstract Abstract. Slender mongooses, Herpestes sanguineus , are solitary but males sometimes form loose, non-aggressive associations. Since 1975, sightings of marked animals in the SerengetiExpand

Parasitism: A cryptic determinant of animal community structure.
Traditionally, the major biotic determinants of animal community structure were assumed to be competition and predation. Recent theoretical, experimental and field studies indicate that parasitism isExpand
