1. Review of thirty-two years of toothed whale strandings in Santa Catarina, southern Brazil (Cetacea: Odontoceti)
ABSTRACT Marine mammal strandings provide valuable insights into local biodiversity. Strandings can be caused by both natural and anthropogenic factors. In the state of Santa Catarina, Southern Brazil, organized marine mammal collections started in the 1980s through opportunistic and non-systematic collection efforts, representing a record of over 30 years o

2. BAT-BORNE RABIES IN LATIN AMERICA
The situation of rabies in America is complex: rabies in dogs has decreased dramatically, but bats are increasingly recognized as natural reservoirs of other rabies variants. Here, bat species known to be rabies-positive with different antigenic variants, are summarized in relation to bat conservation status across Latin America. Rabies virus is widespread i

3. Ecophysiological responses to the effect of annual management on an endemic viviparous fish in central plateau of Mexico
Studies on the biological aspects of fish typically focus on species that currently have commercial value, causing species that lack such market value to be ignored. This is the case of several freshwater fish, specifically of several members of the Goodeidae family. In the State of Querétaro there are several species of this family characterized for being

4. Taxonomy of Ascidae sensu Lindquist and Evans (1965) (Acari: Mesostigmata), biology and ecology of selected Brazilian species / Taxonomia de Ascidae sensu Lindquist e Evans (1965) (Acari: Mesostigmata), biologia e ecologia de espécies brasileiras selecionadas
Mites of the family Ascidae sensu Lindquist and Evans (1965) are found in various habitats, especially in litter, stored products and flowers. They are best known for their predatory habits on mites, other small arthropods and nematodes, but many are also known to feed on fungi, pollen and nectar, and some have been reported in association with cockroaches a

5. Estudo do impacto da construção de duas barragens na dinâmica populacional de mosquitos (Diptera: Culicidae) na região metropolitana de São Paulo / Study the impact of dam construction in two population dynamics of mosquitoes (Diptera: Culicidae) in the Region São Paulo Metropolitan
Assim como qualquer empreendimento que altera localmente o regime de águas, a construção de barragens de abastecimento modifica a ecologia dos culicídeos, podendo levar ao aparecimento de surtos. Foi comparado como foi a resposta dessa comunidade na construção das barragens de Biritiba-Mirim e Paraitinga, entre 2002 e 2005. Ambas fazem parte do Sistema

6. Population ecology of small rodents and marsupials in a semi-deciduous tropical forest of the southeast Pantanal, Brazil
The Pantanal is a South American biome characterized by extensive plains and stark environmental seasonality. Several habitats are subject to annual flooding, forcing small mammal species to aggregate in dry forest patches, which most likely influences their population dynamics and life history strategies. In order to investigate the seasonal influence on th

7. Artificial nests as an alternative to studies of arboreal small mammal populations: a five-year study in the Atlantic Forest, Brazil
Despite the great diversity of Brazilian Atlantic forest small mammals, natural history of most species is unknown due to their cryptic and nocturnal habits, but also due to the inadequacy of methods to capture some species, especially those of arboreal habits. A new technique, based on the use of artificial nests (AN) to record arboreal marsupials, is prese

9. Dinâmica de populações em redes ecológicas : persistências, catástrofes e extinções / Population dynamics in ecological networks : persistence, catastrophes and extinctions
All living organisms interact with individuals of its own species and also with those of other species, forming a complex network of interactions that have an important role in the preservation of the biodiversity. Understanding the underlying behavior and stability of these systems is of fundamental importance to the conservation of these resources. In this

10. Dinâmica de Nutrientes e Redes Tróficas / Nutrient Dynamics and Foods Webs
A food web comprises exchanges of matter and energy that occur among species and between biotic and abiotic environment. Given that abiotic components form the basal resources, the approach of this work consists of evaluating the effects of nutrients input in strategic models that describe food web and chain dynamics. Its focus lies on the determination of t

11. Chemical ecology and reproduction of Neoleucinodes elegantalis Guenée (Lepidoptera : Crambidae) / Ecologia química e reprodução de Neoleucinodes elegantalis Guenée (Lepidoptera : Crambidae)
The reproduction in insects is affected by a wide array of factors that acts directly on the reproductive output, related with offspring quality and quantity: the interaction, by physical, chemical and visual cues, between insects and host plants; the larval growth rate affecting adult size and mating rate, as a mechanism of reproductive sucess. Thus, studie

12. Memória social e ecologia histórica: a agricultura de coivara das populações quilombolas do vale do Ribeira e sua relação com a formação da mata atlântica local / Social memory and historical ecology:slash and burn agriculture in the formation of an Atlantic rainforest area inhabited by quilombola communities, Ribeira Valley, Brazil
The Atlantic Rainforest is one of the worlds most diverse and threatened biomes. The majority of its remnants are located at the Ribeira Valley (SP) where several of the States quilombola populations remain. The Valleys quilombos originated from a population of freed, abandoned or refugee slaves brought to the region in the beginning of the European coloniza
