Rapid tests to assess the nutritional status of plants gerbera can make easier the decision of any adjustments in the fertilization of the substrate. The study was conducted to evaluate nutritionally fertigated gerbera plants with increasing levels of electrical conductivity (EC), using portable meters nitrate and potassium, and chlorophyll. For this, two experiments were conducted. A randomized block design with five levels of EC (0.5, 2.0, 3.5, 5.0 and 6.5 dS m-1) and four replications was used. Cherry cultivar was used in the first experiment. In the second experiment, two cultivars (Cherry and Salmon Rose) were used. In the first experiment, the sap of the leaves was subjected to rapid testing of N-NO3- (equipment Cardy Horiba C -141). N-NO3- and K+ (C-131) were determined in the substrate solution. The intensity of the green leaf, in the second experiment was evaluated with portable Chlorophyll Meter. The N content in the indicator leaf in the first and N and K contents in the plant in the second experiment were determined. Rapid tests are presented as good indicators of the level of N-NO3- and K+ in plant tissue, with the advantages of convenience and speed of determination, facilitating monitoring of fertilization of the substrate by producers and technicians.

The black-tufted-marmoset (Callithrix penicillata), abundant in the southeastern state of São Paulo, is an exotic and invasive species . The present study aimed to study the behavior and make monitoring a population black-tufted-marmoset in man-made environment. The observations were made following the method of scan sampling, which consists of continuous observations with a duration of three minutes with a fifteen-minute intervals between one record and another. The individuals are monitored at two locations on campus, where two groups were identified (with a mean of 3.50 ± 2.06 individuals) totaling 291 hours and 30 minutes of observation. Were determined tree layers used, and observed that the group of EC preferably utilizes the highest stratum, while the group of LCF uses the middle and lower strata. Types of vocalization, such as calling, interaction and alert and frequency and percentage of these were also observed. The food items consumed by the groups that are similar in the two study sites, mostly sap and leaves were diagnosed. From observations of behavioral patterns was possible to construct an ethogram of the species ' Luiz de Queiroz ' campus, comprising the behaviors of vocalization, locomotion, foraging, game, among others. The results may be useful for development of management techniques and for subsequent studies
