To investigate whether the released giant pandas showed a crepuscular
or a diurnal active pattern, we tested whether the diurnal index and crepuscular
index significantly differed from 0 with a t-test at an interval of 10 days.
paca in the study area is in line with that reported by other studies (Donadio et al., 2001; Gomez et al., 2005; Michalski and Norris, 2011; Blake et al., 2012; Kasper et al., 2012b; Huck et al., 2013), although Perez (1992) had suggested a crepuscular
habit for the species.
The predator's crepuscular
activity pattern, comprising 25% of registers, showed a higher activity between 06:00-08:00.
The sharp 12-h peak might represent the crepuscular
pattern described previously.
Dasyprocta punctata es una especie diurna (75.6% de registros obtenidos entre las 8:00 y las 17:59 hs) en el pedemonte, pero con una actividad crepuscular
apreciable (casi 18% de los registros).
index for armadillos was the highest of the three indices, at 39.49 OPH at the beginning of the study, and stayed consistent before dropping to 0.00 OPH in week 9 (Fig.
Median total scent emission was somewhat similar across all five time periods studied, with peaks during crepuscular
periods and in midmorning (1000-1200; Fig.
meowing often becomes a couple's problem.
Biologists know that deer are crepuscular
, meaning that they move and feed primarily at low light (dawn and dusk).
Also, the once crepuscular
red fox shows a preference for nocturnal hunting with presence occurring between 8 pm and 4 am (p-value = 0.0001).
