1. Diet, sexual dimorphism and reproduction of sympatric racers Philodryas aestiva and Philodryas patagoniensis from the coastal Brazilian Pampa
Abstract: Herein we investigated diet, sexual dimorphism and reproductive biology of two sympatric congeneric species at the coastal Brazilian Pampa, Philodryas aestiva and P. patagoniensis. Analysis of the stomach content of the scansorial Philodryas aestiva revealed that it feeds mainly on Anura and small mammals, while it occasionally consumes Insecta, Sq

2. Patterns of arboreal and terrestrial space use by non-volant small mammals in an Araucaria forest of southern Brazil
Apesar dos avanços nas técnicas para pesquisa de pequenos mamíferos arborícolas, dados ecológicos detalhados, tal como padrões de uso do habitat, são praticamente inexistentes para muitas espécies. Utilizando 150 armadilhas de captura viva instaladas no solo, sub-bosque (1,0-5,0m) e dossel (> 5,0m) nós investigamos padrões no uso do espaço arbóre

3. Influence of pitfall trap size and design on herpetofauna and small mammal studies in a Neotropical Forest
One of the most commonly used sampling techniques to capture leaf litter amphibians, lizards and small mammals is a set of pitfall traps with drift fences. However, there are still many speculations concerning the effectiveness of different designs of pitfall traps and the most adequate size of each trap. To address this problem, we conducted the first stand

4. 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

5. Comparison of small mammal prevalence of Leishmania (Leishmania) mexicana in five foci of cutaneous leishmaniasis in the State of Campeche, Mexico
In the Yucatan Peninsula of Mexico, 95% of the human cases of Cutaneous Leishmaniasis are caused by Leishmania (Leishmania) mexicana with an incidence rate of 5.08 per 100,000 inhabitants. Transmission is limited to the winter months (November to March). One study on wild rodents has incriminated Ototylomys phyllotis and Peromyscus yucatanicus as primary res

6. Habitat use by terrestrial mammals in fragments of deciduous seasonal forest / Uso de hábitat de mamíferos terrestres em fragmentos de floresta estacional decidual
The constant environmental degradation, in special the habitat fragmentation, has leading to alterations in mammal populations around de world. Into the Campos de Instrução de Santa Maria (CISM), Santa Maria, State of Rio Grande do Sul/Brazil, it is not different, since the human colonization has led to habitat loss and fragmentation. In this region the Ca

7. PADRÕES DE MOVIMENTO, USO DE MICROHÁBITAT E DIETA DO JACARÉ- PAGUÁ, PALEOSUCHUS PALPEBROSUS(CROCODILIA: ALLIGATORIDAE), EM UMA FLORESTA DE PALEOVÁRZEA AO SUL DO RIO SOLIMÕES, AMAZÔNIA CENTRAL, BRASIL
Survey based on nocturnal counts of Paleosuchus palpebrosus along dry and rainy season were made in flooded forest areas, streams and pounds in the edge of the highway BR-319, kilometer 80, approximately 100 km south of Manaus in the municipal district of Castanho - Central Amazon, for determination of movement patterns, microhabitat use and diet of the spec

8. Fruit removal of a wild tomato, Solanum granulosoleprosum Dunal (Solanaceae), by birds, bats and non-flying mammals in an urban Brazilian environment
A study of removal of fruits of the wild tomato, Solanum granulosoleprosum Dunal (N = 5 plants), by vertebrates was carried out in an urban environment of southern Brazil from January to May 1997 and February 1998. To verify diurnal and nocturnal removals, fruits were counted in several fruit bunches, being classified by size and color. Diurnal observations

9. High-precision 40Ar/39Ar geochronology and the advent of North America’s Late Cretaceous terrestrial fauna
A densely sampled, diverse new fauna from the uppermost Cedar Mountain Formation, Utah, indicates that the basic pattern of faunal composition for the Late Cretaceous of North America was already established by the Albian-Cenomanian boundary. Multiple, concordant 40Ar/39Ar determinations from a volcanic ash associated with the fauna have an average age of 98

10. The location of Z- and W-linked marker genes and sequence on the homomorphic sex chromosomes of the ostrich and the emu
Perhaps the most striking fact about early Cenozoic avian history some 70 million years ago was the rapid radiation of large, flightless, ground-living birds. It has been suggested that, for a time, there was active competition between these large terrestrial birds and the early mammals. Probably reflecting the above noted early start of Ratitae of the infra

11. Large sequence divergence among mitochondrial DNA genotypes within populations of eastern African black-backed jackals.
In discussions about the relative rate of molecular evolution, intraspecific variability in rate is rarely considered. An underlying assumption is that intraspecific sequence differences are small, and thus variations in rate would be difficult to detect or would not affect comparisons among distantly related taxa. However, several studies on mammalian mitoc

12. Hindgut Fermentation in Three Species of Marine Herbivorous Fish
Symbioses with gut microorganisms provides a means by which terrestrial herbivores are able to obtain energy. These microorganisms ferment cell wall materials of plants to short-chain fatty acids (SCFA), which are then absorbed and used by the host animal. Many marine herbivorous fishes contain SCFA (predominantly acetate) in their hindgut, indicative of gut
