White, Bernard Fried*†, and Joseph Sherma Department of Chemistry, Lafayette College, Easton, Pennsylvania 18042. e-mail: [email protected] ABSTRACT: The effects of aestivation or starvation on the neutral lipid and phospholipid content of Biomphalaria glabrata patently infected with Schistosoma mansoni were determined by high-performance thin-layer chromatography–densitometry. Infected–aestivated snails were maintained in a moist chamber at 24 Ϯ 1 C and a relative humidity of 98 Ϯ 1%. Infected–starved snails were maintained in artificial spring water (ASW) at 23 Ϯ 1 C without exogenous food. Infected snails (the controls) were maintained in ASW at 23 Ϯ 1 C and fed lettuce ad libitum. The 3 groups were maintained in the laboratory for 7 days, and then the lipids from the digestive gland–gonad complex (DGG) were extracted and analyzed by class. Infected–aestivated snails exhibited greater mortality rate and weight loss after 7 days than did the infected–starved snails. The steryl ester concentration in the infected–starved snails was significantly increased (P ϭ 0.010) compared with the controls but not compared with infected– aestivated snails; the concentration of phosphatidylcholine in infected–aestivated snails was significantly decreased (P ϭ 0.007) compared with the controls but not when compared with the infected–starved snails. Aestivation or starvation had a significant effect on the concentration of certain lipid classes in the DGG of B. glabrata infected with S. mansoni. Biomphalaria glabrata serves as a host to the medically im- nonaestivated snails. White et al. (2006) investigated neutral portant digenean Schistosoma mansoni. This snail lives in a lipid and phospholipids classes in uninfected–aestivated B. gla- climate that frequently experiences

  • Climate Change and the Genus Rhipicephalus (Acari: Ixodidae) in Africa
    Onderstepoort Journal of Veterinary Research, 74:45–72 (2007) Climate change and the genus Rhipicephalus (Acari: Ixodidae) in Africa J.M. OLWOCH1*, A.S. VAN JAARSVELD2, C.H. SCHOLTZ3 and I.G. HORAK4 ABSTRACT OLWOCH, J.M., VAN JAARSVELD, A.S., SCHOLTZ, C.H. & HORAK, I.G. 2007. Climate change and the genus Rhipicephalus (Acari: Ixodidae) in Africa. Onderstepoort Journal of Veterinary Research, 74:45–72 The suitability of present and future climates for 30 Rhipicephalus species in Africa are predicted us- ing a simple climate envelope model as well as a Division of Atmospheric Research Limited-Area Model (DARLAM). DARLAM’s predictions are compared with the mean outcome from two global cir- culation models. East Africa and South Africa are considered the most vulnerable regions on the continent to climate-induced changes in tick distributions and tick-borne diseases. More than 50 % of the species examined show potential range expansion and more than 70 % of this range expansion is found in economically important tick species. More than 20 % of the species experienced range shifts of between 50 and 100 %. There is also an increase in tick species richness in the south-western re- gions of the sub-continent. Actual range alterations due to climate change may be even greater since factors like land degradation and human population increase have not been included in this modelling process. However, these predictions are also subject to the effect that climate change may have on the hosts of the ticks, particularly those that favour a restricted range of hosts. Where possible, the anticipated biological implications of the predicted changes are explored.

  • Ticks Associated with the Three Largest Wild Ruminant Species in Southern Africa
    Onderstepoort Journal of Veterinary Research, 74:231–242 (2007) Ticks associated with the three largest wild ruminant species in southern Africa I.G. HORAK1*, H. GOLEZARDY2 and A.C. UYS2 ABSTRACT HORAK, I.G., GOLEZARDY, H. & UYS, A.C. 2007. Ticks associated with the three largest wild rumi- nant species in southern Africa. Onderstepoort Journal of Veterinary Research, 74:231–242 The objective of this study was to assess the host status of the three largest southern African wild ruminants, namely giraffes, Giraffa camelopardalis, African buffaloes, Syncerus caffer, and eland, Taurotragus oryx for ixodid ticks. To this end recently acquired unpublished data are added here to already published findings on the tick burdens of these animals, and the total numbers and species of ticks recorded on 12 giraffes, 18 buffaloes and 36 eland are summarized and discussed. Twenty-eight ixodid tick species were recovered. All stages of development of ten species, namely Amblyomma hebraeum, Rhipicephalus (Boophilus) decoloratus, Haemaphysalis silacea, Ixodes pilosus group, Margaropus winthemi, Rhipicephalus appendiculatus, Rhipicephalus evertsi evertsi, Rhipicephalus glabroscutatum, Rhipicephalus maculatus and Rhipicephalus muehlensi were collected. The adults of 13 species, of which the immature stages use small mammals as hosts, namely Haemaphysalis aciculifer, Hyalomma glabrum, Hyalomma marginatum rufipes, Hyalomma truncatum, Ixodes rubi- cundus, Rhipicephalus capensis, Rhipicephalus exophthalmos, Rhipicephalus follis, Rhipicephalus gertrudae, Rhipicephalus

  • Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans
    Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans by Robert George Young A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Integrative Biology Guelph, Ontario, Canada © Robert George Young, March, 2016 ABSTRACT MOLECULAR SPECIES DELIMITATION AND BIOGEOGRAPHY OF CANADIAN MARINE PLANKTONIC CRUSTACEANS Robert George Young Advisors: University of Guelph, 2016 Dr. Sarah Adamowicz Dr. Cathryn Abbott Zooplankton are a major component of the marine environment in both diversity and biomass and are a crucial source of nutrients for organisms at higher trophic levels. Unfortunately, marine zooplankton biodiversity is not well known because of difficult morphological identifications and lack of taxonomic experts for many groups. In addition, the large taxonomic diversity present in plankton and low sampling coverage pose challenges in obtaining a better understanding of true zooplankton diversity. Molecular identification tools, like DNA barcoding, have been successfully used to identify marine planktonic specimens to a species. However, the behaviour of methods for specimen identification and species delimitation remain untested for taxonomically diverse and widely-distributed marine zooplanktonic groups. Using Canadian marine planktonic crustacean collections, I generated a multi-gene data set including COI-5P and 18S-V4 molecular markers of morphologically-identified Copepoda and Thecostraca (Multicrustacea: Hexanauplia) species. I used this data set to assess generalities in the genetic divergence patterns and to determine if a barcode gap exists separating interspecific and intraspecific molecular divergences, which can reliably delimit specimens into species. I then used this information to evaluate the North Pacific, Arctic, and North Atlantic biogeography of marine Calanoida (Hexanauplia: Copepoda) plankton.

    Investigations on the abundance of ectoparasites and vector-borne pathogens in southwest Madagascar Dissertation with the aim of achieving a doctoral degree at the Faculty of Mathematics, Informatics and Natural Sciences Department of Biology University of Hamburg submitted by Julian Ehlers Hamburg, 2020 Reviewers: Prof. Dr. Jörg Ganzhorn, Universität Hamburg PD Dr. Andreas Krüger, Centers for Disease Control and Prevention Date of oral defense: 19.06.2020 TABLE OF CONTENTS Table of contents Summary 1 Zusammenfassung 3 Chapter 1: General introduction 5 Chapter 2: Ectoparasites of endemic and domestic animals in 33 southwest Madagascar Chapter 3: Molecular detection of Rickettsia spp., Borrelia spp., 63 Bartonella spp. and Yersinia pestis in ectoparasites of endemic and domestic animals in southwest Madagascar Chapter 4: General discussion 97 SUMMARY Summary Human encroachment on natural habitats is steadily increasing due to the rapid growth of the worldwide population. The consequent expansion of agricultural land and livestock husbandry, accompanied by spreading of commensal animals, create new interspecific contact zones that are major regions of risk of the emergence of diseases and their transmission between livestock, humans and wildlife. Among the emerging diseases of the recent years those that originate from wildlife reservoirs are of outstanding importance. Many vector-borne diseases are still underrecognized causes of fever throughout the world and tend to be treated as undifferentiated illnesses. The lack of human and animal health facilities, common in rural areas, bears the risk that vector-borne infections remain unseen, especially if they are not among the most common. Ectoparasites represent an important route for disease transmission besides direct contact to infected individuals.

The list is the result of regular queries in numerous journals, books and online publications. It provides a complete list of publication citations as well as a database report containing rearranged subsets of the list sorted by the keyword statistics, extant and extinct genera and species descriptions from the years 2000 to 2017, list of descriptions of extinct and extant species from 2017, parasitology, reproduction, distribution, diet, conservation, and taxonomy. The paper is intended to be consulted for information. In addition, we provide data information on the geographic and depth distribution of newly described species, i.e. the type specimens from the years 1990 to 2017 in a hot spot analysis. New in this year's POTY is the subheader "biodiversity" comprising a complete list of all valid chimaeriform, selachian and batoid species, as well as a list of the top 20 most researched chondrichthyan species. Please note that the content of this paper has been compiled to the best of our abilities based on current knowledge and practice, however, possible errors cannot entirely be excluded.
