| In this work was identifyed the diferents opening forms of the palm nuts Syagrus romanzoffiana by brazilian squirrel Sciurus ingrami in four diferents points of Curitiba, Paraná, Brazil. Was caracterized tive basic forms of opening, in acording with the number of incisions and opening aspects. The form with lower number of incisions (two) was also the greather frequently in the four points sampled (66,25%; N = 5194) well as registred the lower opening time (7,2 ± 1,7 min) in relationship with other forms (9,2 ± 2,3 min). To explicate the diferences in the frequences of forms discovered, is proposed "apprenticeship's hypothesis" which the young squirrels of the population, along the opening nuts apprenticeship, to passing of the forms with larger number of... |

| From October 1994 to November 1995 the behaviour, postures and diurnal activity of tive captive squirrels Sciurus ingrami were observed and registered. Four basics postures, five grooming behaviours, displacements and face wiping behaviour were identified. Based on behavioural observations, the diurnal activity was divided into four categories: resting, displacement, teeding and maintenance. The time spent in each category varied seasonally and the squirrels spent more time resting during winter and spring. However, more time was spent feeding during autum and summer and was reduced the displacement in autum. Two types of breeding behaviour were identified: sexual trailing and mating chase of females by males. However copulatori behaviour was not recorded... |
