Phylogeny of the Acanthocephala based on morphological characters
  • S. Monks
  • Biology, Medicine
  • Systematic Parasitology
  • 2004
TLDR
Strong support is provided for the recognition of Tegorhynchus and Illiosentis as distinct taxa, as well as the transfer of T. pectinarius to Koronacantha and the hypothesis that the Eoacanthocephala is the most primitive group is not supported. Expand
Early Cambrian sipunculan worms from southwest China
TLDR
It is suggested that most typical features of extant sipunculans have undergone only limited changes since the Early Cambrian, thus indicating a possible evolutionary stasis over the past 520 Myr. Expand
Phylogenetic analysis of Pallisentis nagpurensis (Acanthocephala: Quadrigyridae) infecting snakehead murrel Channa striata in Himachal Pradesh, India
TLDR
The present study compiles the morphological characteristics of male and female P. nagpurensis along with the comparison with similar species from same geographical region and reports the first record of 18S, 28S rRNA and ITS1-5.8S-ITS2 gene sequences generated for analyzing the phylogeny within this taxonomic group.

A review of the Acanthocephala parasitising freshwater fishes in Australia
TLDR
Exotic acanthocephalan species have either not been introduced with their exotic hosts or have been unable to establish their life cycles in Australian conditions and have not yet invaded endemic Australian fish hosts. Expand
Constraining the Deep Origin of Parasitic Flatworms and Host-Interactions with Fossil Evidence.
TLDR
The putative record of parasitic flatworms is consistent with extant host associations and so can be used to put constraints on the evolutionary origin of the parasites themselves, which might result in imprecise, but accurate divergence estimates for the evolution of parasitic Flatworms. Expand
The Importance of Fossils in Understanding the Evolution of Parasites and Their Vectors.
TLDR
The potential of the fossil record and other lines of geological evidence to calibrate the origin and evolution of parasitism by combining different kinds of dating evidence with novel molecular clock methodologies is demonstrated. Expand
Paratenic hosts as regular transmission route in the acanthocephalan Pomphorhynchus laevis: potential implications for food webs
TLDR
This work investigated the occurrence and significance both in terms of ecology and evolution of paratenic hosts in the life cycle of the fish acanthocephalan Pomphorhynchus laevis, and demonstrated experimentally, using one of these fish, that they get infected through the consumption of parasitized amphipods and contribute to the parasite’s transmission to a definitive host, hence confirming theirParatenic host status. Expand
Factors influencing parasite-related suppression of mating behavior in the isopod Caecidotea intermedius
TLDR
It is concluded that male isopods do not compensate for a future reproductive loss and chemical cues have been shown to be important in aquatic environments and because predation is necessary for completion of the parasite life cycle. Expand
Chapter Three – ANIMALIA
TLDR
The blastula, a multicellular embryo that forms from the diploid zygote produced by fertilization of a large haploid egg by a smaller haploid sperm, is unique to animals. Expand

A kinetic model of Phanerozoic taxonomic diversity; III, Post-Paleozoic families and mass extinctions
TLDR
The good fit of this model to data on Phanerozoic familial diversity suggests that many of the large-scale patterns of diversification seen in the marine fossil record of animal families are simple consequences of nonlinear interrelationships among a small number of parameters that are intrinsic to the evolutionary faunas and are largely (but not completely) invariant through time.

Aspects of Acanthocephalan reproduction.
TLDR
This chapter focuses on the current knowledge of the ways one population of acanthocephalan parents develops from the preceding population, and reviews the relevant literature and discusses many interesting aspects of acAnthocePhalan reproductive biology. Expand

Parasites and the fossil record
TLDR
This review is concerned primarily with the fossil record and its immediate implications and does not appraise parasite evolution in the light of evidence from sources, often of excellent quality, such as comparative anatomy and physiology or ecology. Expand

Aspects of the biology of a gutless species of Solemya (Bivalvia: Protobranchia)
TLDR
A new species of Solemya is found to lack a gut and has no provision for the collection of food particles, and it is inferred that this species obtains nutriment in the form of dissolved organic molecules. Expand

A new benthic species of the protobranch bivalve genus Solemya, from the northeastern Pacific Ocean, lacks a gut. It has no internal digestive enzymatic apparatus; nor is there any provision for theExpand
