Severe population decline of marsh deer, Blastocerus dichotomus (Cetartiodactyla: Cervidae), a threatened species, caused by flooding related to a hydroelectric power plant

Balancing power production and environmental conservation can be problematic. The objective of this study was to investigate the abundance of marsh deer in the Paraná River Basin, above the Sergio Motta (Porto Primavera) Dam, before and after the impact of the dam closure. A fixed-wing, flat window aircraft was used to survey study transects. Observations were recorded based on the distance sampling line transect method, assuming that the detection probability decreases with increased distance. The abundance of marsh deer in the survey region prior to flooding was estimated to be 974 individuals (CV = 0.23). The overall abundance dropped from 974 to 444 (CV = 0.26) individuals after flooding, an overall reduction of 54%. This reduction can be attributed to the direct impact of the flooding process, but it was likely exacerbated by indirect effects, such as increased disease, hunting, and reduction in food availability. Prior to flooding, the marsh deer was distributed widely throughout the dam's catchment area; however, the marsh deer habitat was almost completely destroyed by the flooding process. This situation highlights the need to implement management strategies that ensure the survival of the remaining fragmented population.

Assessing resistance of ivermectin and moxidectin against nematodes in cattle naturally infected using three different methodologies

The objective of this study was to evaluate the accuracy of the faecal egg count reduction test (FECRT) and the faecal egg count efficacy test (FECET) to assess the resistance status of ivermectin (630 mu g/g) and moxidectin (200 mu g/kg), using the controlled efficacy test as a reference, and whether the results of the EPG are equivalent to the efficacy results from the parasitological necropsies. Two experiments were conducted. The results demonstrate that it was not possible to demonstrate that the EPG values were equivalent with the ivermectin and moxidectin efficacy obtained by parasitological necropsies, mainly if the phenomenon of parasites resistance is not advanced in a determined field population. Maybe the FECET technique would be possibly better than the FECRT. The high anthelmintic efficacy of 200 mu g/kg moxidectin, in naturally infected cattle, against field population of nematodes that are resistant to 630 mu g/kg ivermectin, was observed in this study.

Efficacy of fipronil (1.0 mg/kg) against Rhipicephalus (Boophilus) microplus strains resistant to ivermectin (0.63 mg/kg)

The present study aimed to evaluate the efficacy of fipronil (1 mg/kg) against three strains of ivermectin-resistant Rhipicephalus (Boophilus) microplus (R. (B.) microplus), naturally infesting cattle from different states of Brazil. Three rural properties with a history of macrocyclic lactones ineffectiveness against the cattle tick, and low frequency use of fipronil in the herd, were selected for the study. The animals were randomized according to the mean tick counts, performed on days 3, 2 and I, into three groups with 10 animals each: T01, control (saline solution); T02, subcutaneous ivermectin (0.63 mg/kg) and T03, topical fipronil (1 mg/kg). Treatment was performed on day 0. Counts of partially engorged female ticks were performed on days 3,7 and 14 post-treatment (DPT), and then every 7 days until the 49th DPT. In all three experiments, it was possible to diagnose resistance of R. (B.) microplus to ivermectin (0.63 mg/kg). The maximum efficacy (arithmetic mean) obtained for ivermectin was 64% in experiment II. On the other hand, the formulation containing fipronil (1 mg/kg) reached high efficacy values (>= 97%) in all three experiments. The results from all experiments in this study demonstrate the high efficacy of 1 mg/kg fipronil, administered pour-on in naturally infested cattle, against strains of R. (B.) microplus that are resistant to 630 mcg/kg ivermectin. (C) 2014 Elsevier B.V. All rights reserved.

Desenvolvimento das habilidade de auto-cuidado em crianças com atraso neuropsicomotor

Introduction: The neuropsicomotor development could be negatively affected by several factors occurred in the pre, peri and pos natal period. The early stimulation is implemented by a set of dynamic activities which aim the child development according to the child’s phase. Objective: The purpose of this study was to analyze the functional skills acquisition in the self care area in children with development delay. Participated of this study 9 caregiver of children aged of 0 to 3 years with delay neuropsicomotor. Method: For the data collect was used the self-care area of the Pediatric Evaluation of Disability Inventory (PEDI) in the version adapted for Brazil. The data collect was performed in two different stages, with an interval of 6 months between the collects. The raw score were transformed in continuous score by the Rasch statistics, then was applied the Shapiro-Wilk and t-student test. Results: The participants obtained a signifi cant higher score in the second stage than in the fi rst (p<0,01). Conclusion: The results of the present study suggests that the early stimulation could be an important intervention in the process of self-care skills acquisition in children with neuropsicomotor delay.

Abordagens da biomecânica ortodôntica utilizando mini-implantes

As an innovative transitory anchorage device, the mini-implants deserve to be described with details regarding its use and action during orthodontic treatment. Therefore, this paper intents to present some biomechanic criteria adopted to for a better use of mini-implants as anchorage in anterior retraction (space closure), molar distalization, mesial movement of the molars, intrusion of molars and as support to provisional implant.

Productivity and costs of Beller-Buncher and forest processor in stands of eucalypts in first cut

The rationalization of forest harvesting and minimization costs is a constant search by the managers involved in this process, making them decide practices which are economically viable to optimize that operation. This study aimed to evaluate technically and economically the performance of feller-buncher and the forest processor in stands of eucalypts in first cut. The technique analysis included time and movements, productivity, efficiency operational and mechanical availability. The economic analysis included the parameters operational cost, harvesting cost and energy consumption. Aiming the optimization the cost of forest harvesting, the system composed by feller-buncher and processor forest presented itself as a technically and economically viable alternative to harvesting eucalypt in first cut or stands that do not have bifurcated trees.
