Enríquez, and Peter Marshall PREFACE Biological diversity of México, raptors and scientific research México is one of thc most biologically diverse countries on thc planct, as a result of its very complex gcological history, geographic position, and cnvironmental hcterogcncity, among other factors. lts biological divcrsity is such, that together with 17 othcr countries such as India, China and Brazil, it is rcfcrrcd to as i\fegadiverse. Together, thcsc countrics sustain more than 70% of ali linng organisms, including phnts, anima\s and m1croorganisms, México ranking first for its divcrsity of reptiles and amphibians, thir<l for its mammalian diversity, fourth for irs diversity of vascular plants, and clcvcnth for its diversity of birds. Morcovcr, a high pcrccntage of the species, up to 6S(Y11 in amphibians, are endemic to México; i.c. with gcographic ranges restrictcd to thc country. Toe biological din::rsity of l\léxico has been part of rhc gcographic and natural settings that han:: accompanied its inhabitants sincc thcr first scttlcd in the country more than 12,000 ycars ago. The legendary diversity of thc country has astonishcd scicntists such as Bar<m Alexander Von Hwnbolt, who dcscribcd México as a biolo¿,>ical paradisc. Unfortunately, this impressive natural divcrnity of thc coumry is practically unkninvn by most Mexicans, who imtcad 1;hould be proud of their biological inheritancc. VII Nowadays, thc biological diversity of México is seriously thrcatcned. Hundreds of spccies and thousands of populations are endangered, mainly because of human population size and social inequity. México's population size is expected to become stable around 145 millions, but only in three decadcs. The loss of biological diversit:y has severe consequences at a biological and social level, because populations and species are the basis for the structure and functioning of biological systems, which provide us far free with environmental goods and scrvices. These goods and services, which indude the maintenance of a proper atrnospheric gas composition, the ozone layer, soil fertility and quality and quantity of water, among others, generare the environmental conditions that allow life on Earth. They are the basis of our existence. Paradoxically, their continuancedepends on our activities. The only way to understand the complex relationships of living organisms with their environment, their role in providing environmental services, and better management of these living organisms to reconcile their use with their conservation, is through a solid investment in scicntific rcscarch. However, many governments, induding the Mexican government, surrender to the temptation of investing little in scientific and technological research, focusing on other approaches to fight social and economic problems. Those govcrnments ignore that one of the few ways out of poverty is through the generation of scientific and technological knowledge, which is fundamental to the development of any country. Vlll That is why I havc rcccived with great satisfaction this volumc addrcssing thc ccology and conservation of raptors - one group of species very scnsitivc to anthropogenic disturbanccs. As top predators, with low population sizes, raptors are susceptible to environmcntal changes that can affect them negacively, and thus increase the risk of their extinction. That is precisely why their status is an indication of environmental conditions, much like canary birds long ago used to indicate the prcscncc of toxic gases to mincrs. Toe results presented by researchers working with raptors in México can haYe an immediate applicationin conscnTacion. The carcful c<liting of thc editor has produced an interesting book of high scientific quality. I am surc that time will be the bcst test of thc bcncfits of this type of publications, which are csscntial to maintainthe welfare of our socicty. Gerardo Ccballos México D.F.

  • Detecting Avian Malaria: an Improved Polymerase Chain Reaction Diagnostic
    J. Parasilol, 89(5), 2003, pp. 1044-1047 O American Society of Parasitologists 2003 DETECTING AVIAN MALARIA: AN IMPROVED POLYMERASE CHAIN REACTION DIAGNOSTIC S. M. Fallon, R. E. Ricklefs, B. L. Swanson, and E. Bermingham* Department of Biology, University of Missouri-St. Louis, 8001 Natural Bridge Road, St. Louis, Missouri 63121-4499. e-mail: smfce4@studentmail. umsl. edu ABSTRACT: We describe a polymerase chain reaction (PCR) assay that detects avian malarial infection across divergent host species and parasite lineages representing both Plasmodium spp. and Haemoproteus spp. The assay is based on nucleotide primers designed to amplify a 286-bp fragment of ribosomal RNA (rRNA) coding sequence within the 6-kb mitochondrial DNA malaria genome. The rRNA malarial assay outperformed other published PCR diagnostic methods for detecting avian infections. Our data demonstrate that the assay is sensitive to as few as 10~5 infected erythrocytes in peripheral blood. Results of avian population surveys conducted with the rRNA assay suggest that prevalences of malarial infection are higher than previously documented, and that studies based on microscopic examination of blood smears may substantially underestimate the extent of parasitism by these apicomplexans. Nonetheless, because these and other published primers miss small numbers of infections detected by other methods, including inspection of smears, no assay now available for avian malaria is universally reliable. Avian malaria is caused by a group of apicomplexan species regions of the parasites' genome. Two assays (A and B) were of Plasmodium and Haemoproteus, which infect, among other designed in the nuclear-encoded 18S small subunit (SSU) of tissues, peripheral red blood cells of their vertebrate hosts.

  • Morphology, Taxonomy and Life Cycles of Some Saurian
    MORPHOLOGY, TAXONOMY AND LIFE CYCLES OF SOME SAURIAN HAEMATOZOA by Keith Robert Wallbanks B.Sc. (Lond.) A.R.C.S. 1982 A thesis submitted for the Degree of Doctor of Philosophy of the University of London Department of Pure and Applied Biology Imperial College Silwood Park Ascot Berkshire ii TO MY MOTHER AND FATHER WITH GRATITUDE AND LOVE iii Abstract The trypanosomes and Leishmania parasites of lizards are reviewed. The development of Trypanosoma platydactyli in two sandfly species, Sergentomyia minuta and Phlehotomus papatasi and in in vitro culture was followed. In sandflies the blood trypomastigotes passed through amastigote, epimastigote and promastigote phases in the midgut of the fly before developing into short, slender, non-dividing trypomastigotes in the mid- and hind-gut. These short trypomastigotes are presumed to be the infective metatrypomastigotes. In axenic culture T. platydactyli passed through amastigote and epimastigote phases into a promastigote phase. The promastigote phase was very stable and attempts to stimulate -the differentiation of promastigotes to epi- or trypo-mastigotes, by changing culture media, pH values and temperature failed. The trypanosome origin of the promastigotes was proved by the growth of promastigotes in cultures from a cloned blood trypomastigote. The resultant promastigote cultures were identical in general morphology, ultrastructure and the electrophoretic mobility of 8 enzymes to those previously considered to be Leishmania tarentolae. T. platydactyli and L. tarentolae are synonymised and the present status of saurian Leishmania parasites is discussed. Promastigote cultures of T. platydactyli formed intracellular amastigotes. in mouse macrophages, lizard monocytes and lizard kidney cells in vitro. The parasites were rapidly destroyed by mouse macrophages jlii vivo and in vitro at 37°C.

  • Haemogregarines and Criteria for Identification

Using a self- reporting, we record different haemogregarine species infecting various animal categories and exploring the most systematic features for each life cycle stage. The keystone in the classification of any species of haemogregarines is related to the sporogonic cycle more than other stages of schizogony and gamogony. Molecular approaches are excellent tools that enabled the identification of apicomplexan parasites by clarifying their evolutionary relationships. Abstract: Apicomplexa is a phylum that includes all parasitic protozoa sharing unique ultrastructural features. Haemogregarines are sophisticated apicomplexan blood parasites with an obligatory heteroxenous life cycle and haplohomophasic alternation of generations. Haemogregarines are common blood parasites of fish, amphibians, lizards, snakes, turtles, tortoises, crocodilians, birds, and mammals. Haemogregarine ultrastructure has been so far examined only for stages from the vertebrate host. PCR-based assays and the sequencing of the 18S rRNA gene are helpful methods to further characterize this parasite group. The proper classification for the haemogregarine complex is available with the criteria of generic and unique diagnosis of these parasites.

Eighty-two of the 342 birds (24%) were positive for one or more taxon. Microfilariae were the most commonly seen parasites (10.5%) and Leucocytozoon the least common (0.3%). Other parasites were species of the genera Plasmodium (4.4%), Trypanosoma (3.5%), Hepatozoon (3.5%) and Haemoproteus (3.2%). The low intensity of haemosporidian parasites agreed with other records from the Neotropics. Parasite prevalence in this Neotropical region was higher than levels found in other surveys in the Neotropics, but lower than levels found for the Nearctic area. A new host-parasite association is reported here, as well as avian species examined for haematozoa for the first time. Key words.

    Prevalence of blood parasites in seabirds - a review Quillfeldt et al. Quillfeldt et al. Frontiers in Zoology 2011, 8:26 http://www.frontiersinzoology.com/content/8/1/26 (31 October 2011) Quillfeldt et al. Frontiers in Zoology 2011, 8:26 http://www.frontiersinzoology.com/content/8/1/26 RESEARCH Open Access Prevalence of blood parasites in seabirds - a review Petra Quillfeldt1*, Elena Arriero1, Javier Martínez2, Juan F Masello1 and Santiago Merino3 Abstract Introduction: While blood parasites are common in many birds in the wild, some groups seem to be much less affected. Seabirds, in particular, have often been reported free from blood parasites, even in the presence of potential vectors. Results: From a literature review of hemosporidian prevalence in seabirds, we collated a dataset of 60 species, in which at least 15 individuals had been examined. These data were included in phylogenetically controlled statistical analyses of hemosporidian prevalence in relation to ecological and life-history parameters. Haemoproteus parasites were common in frigatebirds and gulls, while Hepatozoon occurred in albatrosses and storm petrels, and Plasmodium mainly in penguins. The prevalence of Haemoproteus showed a geographical signal, being lower in species with distribution towards polar environments. Interspecific differences in Plasmodium prevalence were explained by variables that relate to the exposure to parasites, suggesting that prevalence is higher in burrow nesters with long fledgling periods. Measures of Plasmodium, but not Haemoproteus prevalences were influenced by the method, with PCR-based data resulting in higher prevalence estimates. Conclusions: Our analyses suggest that, as in other avian taxa, phylogenetic, ecological and life-history parameters determine the prevalence of hemosporidian parasites in seabirds.
