SUMMARY The aim of the present study was to analyze the status of the American Tegumentary Leishmaniasis (ATL) in the state of Rio de Janeiro, from 2004 to 2013, through its spatiotemporal distribution. We also described variables considered relevant to the epidemiology of the disease, such as the clinical form, gender, ethnic group, age group, and progression of disease. This is a descriptive study, which used notified secondary data from the Brazilian Information System of Notifiable Diseases (SINAN), Ministry of Health, Brazil, regarding confirmed diagnoses. To help the calculation of coefficients of detection and mortality, we used population data from the Brazilian Institute of Geography and Statistics (IBGE). We analyzed 1,470 cases of ATL with the predominance of the cutaneous clinical form (1,292/87.89%). The data has also revealed seven deaths, a predominance of males (922/62.72%), and a higher incidence of ATL in the white ethnic group (731/49.72%). We observed a high incidence of ATL in the group of 20 - 39 years old (477/32.44%). We concluded that there was a decrease in the number of ATL cases in the state of Rio de Janeiro, based on a coefficient of detection of 1.44/100.000 inhabitants in 2004 decreasing to 0.20/100.000 inhabitants in 2013. The localities with the highest occurrences of ATL were the metropolitan region (843 cases) and the municipality of Rio de Janeiro (740 cases). In 2005, the highest incidence of the disease was observed (351 cases) in the study. Among the variables selected to describe the epidemiology of the disease, the following categories: cutaneous clinical form, male patients, white ethnic group, and the age group of 20 - 39 years old were more affected than the others.

Th e Neotropic Cormorant Nannopterum brasilianus (Gmelin, 1789) is one of the most common and abundant species in Brazil's aquatic environments, but little is known about its natural history. Th is study elaborates and quantitatively evaluates the ethogram and seasonal abundance of this species at Lake Açu, in Rio de Janeiro, Brazil. Between August 2013 and July 2014, behaviors were registered by the ad libitum sampling method and quantifi ed by the continuous recording during 30-min sessions. Th e mean number of sighted individuals per month was 30.41 ± 4.79. Abundance was higher during the dry season (41.5 ± 5.36) compared to the rainy season (19.33 ± 4.81) (t = 3.07, P = 0.01). A total of 42 behaviors were described and grouped into fi ve behavioral categories: maintenance (83.59%), ingestion/excretion (10.67%), locomotion (3.48%), play (1.65%), and agonistic behavior (0.61%). Th e time spent in these categories did not vary signifi cantly between the morning and afternoon periods. Th is study can be used as a starting point for further ethological studies on the species.
