Abstract:
We report State-and-Transition Models for Uruguayan grasslands built upon a methodological approach that objectively defined states/phases associated, a priori, to rangeland management. Such approach was based on randomly sampled areas corresponding to mapped grassland communities. Each sampled area matched a MODIS pixel. Vegetation structural indicators were recorded in every pixel. After a multivariate analysis, field observations were grouped according to similarities in terms of structure, and different "states" and "phases" were identified. Ecosystem functioning and the supply of regulating ecosystem services were estimated for each grassland state/phase using the normalized difference vegetation index (NDVI) derived from MODIS sensor. Finally, workshops were held in order to detect local stakeholders? perceptions, and to discuss the management practices to promote the desired transitions among phases. Results were presented for two vegetation units of the Basaltic ?Cuesta? region. The ?inductive approach? applied not only led to the description of ?states?, but also to the identification of more subtle changes in vegetation ("phases"). Our approach minimized biases due to personal experience as well as differences derived from using different observation protocols. The two vegetation units presented an internal heterogeneity associated to changes in basal stratum height, total cover, stratification, frequency of decreasing species due to grazing, and proportion of plant functional types. The ecosystem functioning descriptors of each phase responded to extreme climatic events differently. Based on stakeholder?s opinions and experiences, stocking rate, sheep/cattle ratio, and grazing method were the main management practices promoting the transition among phases. MenosAbstract:

ABSTRACT:
This study aimed to determine control measures for gastrointestinal nematodes in goats in the northeastern semiarid after analyzing the dynamics of gastrointestinal helminths during the drought, the evolution of the parasitic load after the first rains and the differences in susceptibility between goats of different categories and ages. Five farms were studied from March 2013 to January 2015. Feces were collected from all goats every month, for fecal egg counts (FECs). No treatment was required on any farm during the dry period. In 2013, with annual rainfall of 265-533 mm, treatments were not necessary during the rainy season. However, in 2014, with rainfall of 604-778 mm, treatments were necessary 60-90 days, after the first rains. On three farms, gastrointestinal nematodes showed multiple anthelmintic resistance. The FECs from lactating goats were significantly higher than from dry and young goats. In conclusion, in the Brazilian semi-arid region (Caatinga biome), it is generally unnecessary to treat grazing goats during the dry season. In the rainy season, the parasite load increases 2-3 months after the first rains. In both, the dry and the rainy season, farmers should monitor their herds by means of FEC or another criterion (anemia or submandibular edema), to determine the need to treat
RESUMO:Este trabalho objetivou determinar medidas de controle de nematódeos gastrintestinais de caprinos no semiárido nordestino após análise da dinâmica das infecções helmínticas durante a seca, a evolução da carga parasitária após as primeiras chuvas e as diferenças de susceptibilidade entre caprinos de distintas categorias e idades. Em cinco propriedades, de março de 2013 a janeiro de 2015, foram coletadas, mensalmente, fezes de todos os caprinos para contagem de ovos. Em nenhuma propriedade foi necessário vermifugar durante os períodos de seca. Em 2013, com precipitações de 265-533 mm anuais, não foi necessário vermifugar durante o período de chuva. No entanto, em 2014, com precipitações de 604-778 mm, foi necessário vermifugar 60-90 dias após as primeiras chuvas em três propriedades. Nessas três propriedades foi encontrada multirresistência aos anti-helmínticos. Foi constatado que o OPG das cabras lactantes foi significativamente maior do que o OPG das cabras secas e dos cabritos. Em conclusão, na região semiárida, geralmente, não é necessário o tratamento das cabras pastejando na caatinga durante a estação seca. Na estação chuvosa, a carga parasitária aumenta 2-3 meses após as primeiras chuvas. Tanto na seca quanto nas chuvas, o produtor deve monitorar o rebanho mediante OPG ou por outros critérios (anemia, edema submandibular) para determinar a necessidade de vermifugação. MenosABSTRACT:
