| El sobre pastoreo causa la compactación del suelo y pérdida de la vegetación y cuando es insuficiente la biomasa vegetal, se suele invadir bosques o selvas en búsqueda de alimento para el ganado lo que deteriora los ecosistemas. Como una alternativa surge el pastoreo con enfoque holístico (PH) en el que se favorece la productividad animal sin afectar el entorno. Por ello, en el presente estudio se evaluó de febrero-2008 a enero-2009 el PH en bosque de encino con una manada mixta de equinos, bovinos, ovinos, caprinos y porcinos y su efecto sobre la fertilidad química edáfica, la vegetación nativa y la productividad del ganado. Se colectaron muestras de suelo (99 en PH y 102 sin pastoreo) a 0-5 cm, 5-10 cm y 10-20 cm de profundidad y <5%, 5-15%, 15-30% y... |

| Given that few studies have valued the provisioning services of temperate southern African wetlands, research on this topic was undertaken in a remote rural wetland, Letseng-la-Letsie, in Lesotho and a peri-urban wetland in Mfuleni, Cape Town. The objectives were to quantify incomes from wetland resources, assess the relative dependency of communities on wetland provisioning services, and estimate the total provisioning value of the wetlands. Data were collected from informal interviews and structured household surveys. Despite the different settings, both wetlands were used mainly for grazing livestock. The estimated total value added during 2007 from grazing was U.S. $180,078 for Letseng-la-Letsie and U.S. $540,286 for Mfuleni. Letseng-la-Letsie and... |

| Land-cover change has been identified as one of the most important drivers of change in ecosystems and their services. However, information on the consequences of land cover change for ecosystem services and human well-being at local scales is largely absent. Where information does exist, the traditional methods used to collate and communicate this information represent a significant obstacle to sustainable ecosystem management. Embedding science in a social process and solving problems together with stakeholders are necessary elements in ensuring that new knowledge results in desired actions, behavior changes, and decisions. We have attempted to address this identified information gap, as well as the way information is gathered, by quantifying the... |

| In the drylands of northern Kenya, as elsewhere in Africa, traditional pastoralist social-ecological systems are undergoing profound transformations. Diminishing resource availability, changing social values and governance systems, and new resource management institutions challenge the capacity of communities for effective common pool resource management. Individuals’ values and environmental perceptions play a substantial role in decision making regarding resource use and management. Additionally, social capital within communities can influence cooperative and adaptive resource management. We studied five Laikipia Maasai communities in Kenya, which share a common natural environment, history, and political organization. We surveyed... |

| Nearly forty percent of mankind depend in one way or another on mountain ecosystems. Local ecosystem services are slope stability, water yield, agricultural products or recreational value. Continental scale influences include drinking water supply, ground water recharging, irrigation water, hydroelectric power, flood control, traffic routes etc. In this paper I review evidence of alpine ecosystem responses to global change. It is emphasized that soil conservation is the centerpiece of any consideration of sustainable land use in alpine terrain. Complete vegetation cover of high biological diversity is essential to protect soils and secure `ecosystem services' in upland systems. It is illustrated that this is not necessarily in conflict with land use and... |

| A observação visual do comportamento ingestivo em ruminantes, principalmente naqueles mantidos em pastagens, apesar de comumente utilizada com diferentes finalidades de estudo, é trabalhosa, pouca precisa e empenha grande quantidade de mão-de-obra. Com o avanço da tecnologia em geral, outras metodologias, que fazem uso de sensores mecânicos, ópticos e sonoros, mostram grande potencial de uso em ruminantes. A bioacústica, em particular, adequa-se em experimentos que necessitam tanto de macro quanto de microatividades, otimizando mão-de-obra e com custo relativamente baixo em comparação à outras metodologias automatizadas. Entretanto, por ser um campo de estudo recente na produção animal, as operações de captura e análise dos sons ainda precisam ser... |

| A avaliação de forrageiras com animais sob sistema de pastejo se constitui em uma área de extrema importância para a bovinocultura de corte em todo o mundo, e em especial nos paises tropicais e subtropicais como o Brasil, que tem como característica e como vantagem econômica a produção de carne bovina fundamentada em pastagens. No entanto, para que os resultados deste tipo de avaliação sejam de utilidade pratica e se transformem em incrementos de produtividade e de eficiência bioeconômica do sistema de produção, faz-se necessário que esta seja conduzida,considerando-se a existência de dois sistemas bem definidos, quais sejam, pastagem e animal. E importante ainda, alem do entendimento dos inter-relacionamentos destes dois sistemas, conhecer as relações em... |

| Arachis pintoi, commonly known as forage peanut, is a leguminous plant with good forage yield and nutritional quality adapted to the Brazilian environmental conditions and used in grass/legume pastures or preserved as silage or hay. In this study, we evaluated the nutritional value and dry matter losses of silages produced with different proportions of forage peanutcv. BRS Mandobi and elephant grass. Five levels of substitution of elephant grass (0, 25, 50, 75, and 100%, fresh matter basis) for the legume were tested in a completely randomized design with four replicates. The fiber components of the silages, except lignin, decreased with higher levels of forage peanut. Crude protein content and in vitro dry matter digestibility presented maximum values of... |
