Activity pattern of Cuniculus paca (Rodentia: Cuniculidae) in relation to lunar illumination and other abiotic variables in the southern Brazilian Amazon Rev. Bras. Zool.
Michalski,Fernanda; Norris,Darren.
Understanding what influences the activity of organisms is important for both ecological understanding and species conservation. Using data from 2,707 camera trap days distributed across 24 forest sites, we present quantitative analyses of the activity pattern of Cuniculus paca (Linnaeus, 1766) in southern Amazonia. We compared the activity pattern of this species across four designated subsets of the 24-hours diel cycle (dawn, dusk, day and night). Using linear regression models we tested the influence of season, temperature and rainfall on the activity patterns of C. paca (paca). We also evaluated the nocturnal photos of paca (N = 111) as a function of the degree of lunar illumination in order to test the prediction that pacas minimize their activity...

Temporal distribution of five bat species (Chiroptera, Phyllostomidae) from Panga Reserve, south-eastern Brazil Zoologia
Pedro,Wagner A.; Taddei,Valdir A..
Data about activity patterns, hourly and monthly, on five phyllostomid bats, Glossophaga soricina (Pallas, 1766), Anoura caudifer (E. Geoffroy, 1818), Camilla perspicillata (Linnaeus, 1758), Sturnira lilium (E. Geoffroy, 1810) and Platyrrhinus lineatus (E. Geoffroyi, 1810), studied over a one year period at the Panga Ecological Reserve, Uberlandia, Minas Gerais state, south-eastern Brazil, are reported and discussed.

Activity patterns of nine phyllostomid bat species in a fragment of the Atlantic Forest in southeastern Brazil Zoologia
Aguiar,Ludmilla Moura de Souza; Marinho-Filho,Jader.
Seasonal, monthly and hourly activity patterns of nine bat species were studied based on their capture rates at the Reserva Particular do Patrimônio Natural Feliciano Miguel Abdala (RPPN-FMA), Caratinga, Minas Gerais state, southeastern Brazil. The frugivorous and nectarivorous bat species have their activity closely related to the availability of food. Divergence in monthly and hourly activity is discussed for pairs of similar species and the hypothesis of reduction in competition for nectarivorous and frugivorous species are rejected. Further studies on frugivores-plants interactions should be conducted to assess the long term consequences for the whole system at the RPPN-MFA.
