There is currently a lot of interest in determining the state of Brazilian grasslands. Governmental actions and programs have recently been implemented for grassland recovery in Brazilian states, with the aim of improving production systems and socioeconomic indicators. The aim of this study is to evaluate the vegetative growth, temporal vigor, and long-term scenarios for the grasslands in Zona da Mata, Minas Gerais State, Brazil, by integrating phenological metrics. We used metrics derived from the normalized difference vegetation index (NDVI) time series from moderate resolution imaging spectroradiometer (MODIS) data, which were analyzed in a geographic information system (GIS), using multicriteria analysis, the analytical hierarchy process, and a simplified expert system (ESS). These temporal metrics, i.e., the growth index (GI) for 16-day periods during the growing season; the slope; and the maximum, minimum, and mean for the time series, were integrated to investigate the grassland vegetation conditions and degradation level. The temporal vegetative vigor was successfully described using the rescaled range (R/S statistic) and the Hurst exponent, which, together with the metrics estimated for the full time series, imagery, and field observations, indicated areas undergoing degradation or areas that were inadequately managed (approximately 61.5%). Time series analysis revealed that most grasslands showed low or moderate vegetative vigor over time with long-term persistence due to farming practices associated with burning and overgrazing. A small part of the grasslands showed high and sustainable plant densities (approximately 8.5%). A map legend for grassland management guidelines was developed using the proposed method with remote sensing data, which were applied using GIS software and a field campaign.

Resumo: O leite de cabra apresenta-se como uma importante alternativa para diminuir a desnutrição, devido suas características nutricionais, mas para ser consumido necessita de padrões de qualidade exigidos pela legislação vigente. Uma patologia que interfere diretamente na produção do leite é a mastite, principalmente subclínica, pois além de diminuir a produção, ainda causa danos a saúde da glândula mamária. Objetivou-se nesse trabalho identificar e caracterizar bioquimicamente estirpes de Staphylococcus spp. isoladas de amostras de leite de cabra. Foram colhidas 240 amostras de leite de 30 animais que não apresentavam sinais evidentes de mastite clínica e levadas ao Laboratório de Microbiologia da Embrapa Caprinos e Ovinos para isolamento e identificação fenotípica dos possíveis agentes patogênicos. Obteve-se como resultado um total de 83 amostras com multiplicação microbiana, sendo estafilococos coagulase-negativos (SCN) o agente etiológico mais isolado, confirmando outras pesquisas que afirmam estes serem os principais patógenos causadores de mastite subclínica em cabras. [Identification and biochemical characterization of strains of Staphylococcus spp. isolates from goat milk samples]. Abstract: Goat's milk is presented as an important alternative to reduce malnutrition because their nutritional characteristics, but for consumption needs more attention as the quality standards. A condition that interferes directly in the production of milk is mastitis, especially subclinical, as well as reducing production also damages the health of the mammary gland. The objective of this work is to identify and characterize biochemically strains of Staphylococcus spp. isolated from goat milk samples. Were collected 240 samples from 30 animals milk that had no signs of clinical mastitis and taken to the Microbiology Laboratory of Embrapa Goats and Sheep for isolation and phenotypic identification of possible pathogens. Was obtained as a result a total of 83 samples with bacterial multiplication, and Staphylococcus negative coagulases (SCN) as etiologic agent, confirming other studies that say these are the main pathogens of subclinical mastitis in goats MenosResumo: O leite de cabra apresenta-se como uma importante alternativa para diminuir a desnutrição, devido suas características nutricionais, mas para ser consumido necessita de padrões de qualidade exigidos pela legislação vigente.
