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:

RESUMO:O objetivo do presente trabalho é descrever os principais aspectos epidemiológicos, clínico-patológicos e radiológicos de malformações em pequenos ruminantes no semiárido do estado da Bahia. Foram realizadas visitas técnicas em 41 propriedades rurais no município de Uauá, Bahia, e em cada uma delas foi aplicado um questionário epidemiológico. Adicionalmente, quando se observavam casos de malformações, os animais eram avaliados vivos ou mortos. Foram necropsiados oito animais (1, 2, 3, 4, 5, 6, 7 e 8), e dois (7 e 8) foram submetidos a exame radiográfico. Sobre a alimentação do rebanho, 40 (97,56%) produtores rurais relataram o livre acesso de seus animais à vegetação nativa. Em relação à presença de Mimosa tenuiflora, 5 (12,2%) informaram que os animais tinham acesso à planta, 15 (36,6 %) disseram que tinham pouco contato, enquanto que 21 (51,2 %) relataram que não havia nenhum contato com a planta, pois essa espécie não estava presente em número relevante na região. Vinte e cinco dos 41 proprietários (60,98%) relataram o consumo de Poincianella pyramidalis. Foi constatado ainda que na maioria das propriedades havia muitas áreas invadidas por P. pyramidalis (80-90% da vegetação). As principais anormalidades relatadas pelos entrevistados em 36 propriedades foram artrogripose (87,80%), agnatia [22 (53,66%)], desvio lateral da mandíbula [11 (26,82%)], escoliose [6 (14,63%)], micrognatia [6 (14,63%)], fenda palatina [4 (9,75%)], crânio aumentado de tamanho [4 (9,75%)], microftalmia [2 (4,88%)], braquignatismo [1 (2,43%)], exoftalmia [1 (2,43%)] e deformidades múltiplas no crânio [1 (2,43%)]. No exame clínico de 13 animais com malformações, as principais alterações foram artrogripose bilateral dos membros torácicos (6/13); queilosquise (2/13); micrognatia (1/13) e má oclusão dentária (1/13). Considerando que algumas dessas malformações foram reproduzidas experimentalmente em caprinos pode-se sugerir P. pyramidalis como mais uma planta teratogênica para ruminantes no Nordeste do Brasil.
ABSTRACT: The aim of this paper is to describe the epidemiological, clinical-pathological and radiological aspects of malformations in small ruminants in the semi-arid state of Bahia. Technical visits were carried out in 41 rural properties in the city of Uauá, Bahia, and in each of them, an epidemiological questionnaire was applied. In addition, when malformations were observed, the animals were evaluated alive or dead. Eight animals (1, 2, 3, 4, 5, 6, 7 and 8) were necropsied, and two (7 and 8) were submitted to radiographic examination. Regarding the feeding of the herd, 40 (97.56%) farmers reported the free access of their animals to the native vegetation. Regarding the presence of Mimosa tenuiflora, 5 (12.2%) said that the animals had access to the plant, 15 (36.6%) was informed they had little contact, while 21 (51.2%) reported that there was no contact with the plant, because this species were not present in a relevant number in the region. Twenty five out of 41 owners (60.98%) reported the consumption of Poincianella pyramidalis. It was also verified that in the majority of the properties there were many areas invaded by P. pyramidalis (80-90% of the vegetation). The main abnormalities reported by the interviewees on 36 properties were arthrogryposis (87.80%), agnatia [22 (53.66%)], lateral deviation of the mandible [11 (26.82%)], scoliosis [6 (14.63%)], micrognathia [6 (14.63%)], cleft palate [4 (9.75%)], skull enlarged in size [4 (9.75%)], microphthalmia [2 (4.88%)], braquignatism [1 (2.43%)], exophthalmia [1 (2.43%)] and, multiple deformities in the skull [1 (2.43%)]. In the clinical examination of 13 animals with malformations, the main alterations were bilateral arthrogryposis of the thoracic limbs (6/13); cleft lip (2/13); micrognathia (1/13) and dental malocclusion (1/13). Considering that some of these malformations were reproduced experimentally in goats, it is possible to suggest P. pyramidalis as another teratogenic plant for ruminants in Northeast Brazil.
