1. A Bayesian analysis of the parasitic ecology in Jenynsia multidentata(Pisces: Anablepidae)
ABSTRACT Jenynsia multidentata Jenyns, 1842 (one-sided livebearers) are euryhaline viviparous fish of small size, used in the laboratory experiment, important as resource for biological control of mosquito’s larva and a key species to recover eutrophic lakes. Works have been published dealing with parasite biodiversity of this host, but little has been stu

2. Studies on protozoa in ancient remains - A Review
Paleoparasitological research has made important contributions to the understanding of parasite evolution and ecology. Although parasitic protozoa exhibit a worldwide distribution, recovering these organisms from an archaeological context is still exceptional and relies on the availability and distribution of evidence, the ecology of infectious diseases and

4. Biodiversidade dos helmintos parasitos dos roedores simpátricos Oligoryzomys nigripes e Akodon spp. (Rodentia: Sigmodontinae), na Mata Atlântica, / Biodiversity of helminth parasites in the sympatric rodents Oligoryzomys nigripes and Akodon spp. (Rodentia: Sigmodontinae), in the Atlantic Forest, Teresópolis,
O objetivo deste trabalho foi descrever a composição e estrutura da comunidade helmíntica comparando a comunidade componente e a infracomunidade dos helmintos das populações de roedores simpátricos Akodon spp. e Oligoryzomys nigripes na Mata Atlântica e os diferentes tamanhos de fragmentos e a reserva do Parque Nacional da Serra dos Órgãos (PARNASO)

5. Pathoecology and paleodiet in Postclassic: Historic Maya from northern coastal Belize
This paper examines the synergism among diet, disease, and ecology at two related coastal Maya sites in Belize (Marco Gonzalez and San Pedro) for the Postclassic and Historic periods (1350-1650 AD), which immediately follow the Classic period collapse. Stable carbon- and nitrogen-isotope ratios in collagen and stable carbon-isotope ratios in structural carbo

6. Structure and compositon of the metazoan parasite communities of the Aspistor luniscutis and Genidens barbus (Osteichthyes: Ariidae) and Anchoa marinii and A. tricolor (Osteichthyes: Engraulididae) from the coastal zone of the State of Rio de Janeiro, Brazil. / Composição e estrutura das comunidades de metazoários parasitos de Aspistor luniscutis e Genidens barbus (Osteichthyes: Ariidae) e Anchoa marinii e A. tricolor (Osteichthyes: Engraulididae) do litoral do estado do Rio de Janeiro, Brasil
Between March 2000 and February 2003 63 specimens of sea catfishes G. barbus and 69 specimens of A. luniscutis and Between October 2001 and July 2003, 103 specimens of anchovies A. tricolor and 95 specimens of A. marinii from the coastal zone of the State of Rio de Janeiro (2301 S, 4338 - 4419 W), Brazil, were necropsied to study their communities of metazoa

7. Ecologia da interação entre formigas invasoras e moscas parasitoides
The establishment of exotic species is an important disturbing factor of native community. The knowledge of the ecology of these invading species in their native range is fundamental to handle effectively the problem. The red fire ant, Solenopsis invicta Buren, and the Argentine ant, Linepithema humile (Mayr), are invading species in many places, bringing ec

8. Sloth biology: an update on their physiological ecology, behavior and role as vectors of arthropods and arboviruses
This is a review of the research undertaken since 1971 on the behavior and physiological ecology of sloths. The animals exhibit numerous fascinating features. Sloth hair is extremely specialized for a wet tropical environment and contains symbiotic algae. Activity shows circadian and seasonal variation. Nutrients derived from the food, particularly in Bradyp

9. Microhabitat preferences of Biomphalaria pfeifferi and Lymnaea natalensis in a natural and a man-made habitat in Southeastern Tanzania
Schistosoma mansoni is an important human parasitic disease which is widespread throughout Africa. As Biomphalaria pfeifferi snails act as intermediate host, knowledge of their population ecology is an essential prerequisite towards understanding disease transmission. We conducted a field study and assessed the density and microhabitat preferences of B.p

10. Characterization of an Extracellular Protease from the Insect Pathogen Xenorhabdus luminescens
Xenorhabdus luminescens Hm cultured in gelatin broth produced a single extracellular protease. The protease was purified by a factor of 500 and characterized as a monomeric protein with an approximate molecular weight of 61,000. On the basis of inhibitor studies and its pH optimum, the protease was classified as an alkaline metalloprotease with a pH optimum

11. Ecology Drives the Worldwide Distribution of Human Diseases
Identifying the factors underlying the origin and maintenance of the latitudinal diversity gradient is a central problem in ecology, but no consensus has emerged on which processes might generate this broad pattern. Interestingly, the vast majority of studies exploring the gradient have focused on free-living organisms, ignoring parasitic and infectious dise

12. Health Impacts of Environmental Mycobacteria†
Environmental mycobacteria are emerging pathogens causing opportunistic infections in humans and animals. The health impacts of human-mycobacterial interactions are complex and likely much broader than currently recognized. Environmental mycobacteria preferentially survive chlorination in municipal water, using it as a vector to infect humans. Widespread chl
