1. Occurrence of gastrointestinal parasites in wild animals in State of Paraná, Brazil
ABSTRACT The objective of this study was to determine the prevalence and diversity of gastrointestinal parasites in fecal samples from wild birds and mammals from the State of Paraná. In total, 220 stool samples were sent to Parasitic Diseases Laboratory of the Federal University of Paraná during 13 months (Jan/2013-Jan/2014). A total of 52.7% (116/220) of

2. Trypanosoma cruzi strain TcIV infects raccoons from Illinois
BACKGROUND The northern limits of Trypanosoma cruzi across the territory of the United States remain unknown. The known vectors Triatoma sanguisuga and T. lecticularia find their northernmost limits in Illinois; yet, earlier screenings of those insects did not reveal the presence of the pathogen, which has not been reported in vectors or reservoir hosts in

3. Genetic evidence of enzootic leishmaniasis in a stray canine and Texas mouse from sites in west and central Texas
We detected Leishmania mexicana in skin biopsies taken from a stray canine (Canis familiaris) and Texas mouse (Peromyscus attwateri) at two ecologically disparate sites in west and central Texas using polymerase chain reaction (PCR). A single PCR-positive dog was identified from a sample of 96 stray canines and was collected in a peri-urban area in El Paso C

4. Isolation of Escherichia coli and Salmonella spp. from free-ranging wild animals
Increasing interactions between humans, domestic animals and wildlife may result in inter-species transmission of infectious agents. To evaluate the presence of pathogenic E. coli and Salmonella spp. and to test the antimicrobial susceptibility of isolates, rectal swabs from 36 different free-ranging wild mammals were taken from two distinct natural sites in

5. Genética aplicada à ecologia de estradas: um estudo na estrada municipal Guilherme Scatena (São Carlos, SP) e potencial impacto na biodiversidade local.
Roads generate a large ecological impact to wildlife by raising barriers among ranges of species originally continuous and for causing road-kills. After road-killing, a morphological identification becomes impossible for the loss of diagnostic features, especially in the case of small vertebrates. Use of molecular tools for identification is an alternative t

6. Agentes infecciosos e dieta de carnívoros domésticos e silvestres em área de silvicultura do Alto Paranapanema: implicações para a conservação / Infectious agents and diet of domestic and wild carnivores in a silvicultural area in Alto Paranapanema: implications for conservation
Apesar do estado de São Paulo ter uma área de vegetação nativa pequena e, em sua maioria, altamente fragmentada, isolada e imersa em matrizes agrícolas em propriedades privadas, seu território ainda alberga um número considerável de espécies silvestres, inclusive nessas áreas comerciais. Para a elaboração de planos de manejo ecologicamente corret

7. Efeitos do inseticida endossulfam sobre a morfologia e a morfometria testicular em morcegos frugívoros Artibeus lituratus (OLFERS, 1818) / Effects of the endosulfan on the testicular morphology and morphometry in fruit bats Artibeus lituratus (OLFERS, 1818)
Large amounts of agricultural chemicals are discharged into the environment in Brazil. These pesticides are often used to destroy or impair the activity of organisms that attack crops. There are some reports in the literature concerning the decline of many wildlife populations as a result of contamination of their habitats by pesticides. One of the putative

8. Pequenos mamíferos terrestres e a regeneração da Mata Atlântica: influência da estrutura do habitat e da disponibilidade de alimento na recuperação da fauna / Terrestrial small mammals and Atlantic forest regeneration: effect of habitat structure and food availability in the wildlife recovery
Através da amostragem de 28 sítios em diferentes estádios de regeneração em uma área de Mata Atlântica contínua, procuramos nesta dissertação contribuir para o entendimento dos mecanismos relacionados às mudanças faunísticas observadas durante o processo de regeneração em florestas tropicais, e, assim, melhor compreender o valor das florestas

9. Avaliação do sistema estomatognático e de sincrânios de lobo-guará (Chrysocyon brachyurus) em vida livre e cativeiro / Oral and skull evaluation of captive and wildlife maned wolves (Chrysocyon brachyurus)
The maned wolf, Chrysocyon brachyurus, is the largest wild canid inhabiting South America, specially areas with tall grass, fence and bush forest. They are omnivorous and their most important dietary components are small mammals, reptiles, insects, forage plants and fruits. There are few studies about oral diseases in free-ranging and captive maned wolves. T

10. Non-invasive endocrine monitoring using fecal steroid analysis: opportunities and challenges
During the past two decades, techniques for the non-invasive analysis of fecal steroid metabolites (estrogen, androgen, progestagen and glucocorticoid metabolites) have been developed. These techniques have been used for research with mammals, birds, reptiles, and to a lesser extent in fish; species studied included domestic and laboratory animals, as well a

11. Artificial nest predation: application, challenges and perspectives for the tropical areas / Predação de ninhos artificiais: aplicações, desafios e perspectivas para as áreas tropicais
The natural predation of the nests has been suggested as the principal cause to the decline of bird population, acting on the performance and community structure. Due to the difficulty of natural nest localization and monitoring, the artificial nests are used as a fast alternative to check the avian reproductive success. The artificial nest studies are widel

12. Comunidade de mamiferos não-voadores de um fragmento de floresta Atlantica semidecidua do municipio de Campinas, SP
The population richness, composition, abundance and density of non-volant mammals of mata Ribeirão Cachoeira forest, a 230 ha semideciduous forest fragment in the outskirts of Campinas, São Paulo, were studied between 2001 and 2003. The main objective was to evaluate the importance of this forest fragment to the local and regional conservation of the nativ
