The influence of re-wetting of pastures on the occurrence of important endoparasites in cattle was monitored over the course of three years. The study was conducted on a peninsula at the German North-Sea Coast. The cattle were stabled from November to April. During summer season, they were kept on pastures included in a nature protection program differentiating between three states of re-wetting. Faecal samples from randomly selected animals were analysed with routine diagnostic methods for the occurrence of Eimeria spp., nematode and trematode eggs and lungworm larvae.

Selected environments ranging from cultivated soils under vines and olive groves to sequential abandonment with forest, meadow and scrub cover were investigated for their impact on relevant physical and chemical properties in the shallow soils of the Cap de Creus Peninsula (NE Spain). Both insufficient agricultural practices and periodical wildfire occurrence in abandoned areas were focused as components triggering degradation processes. Despite that, less fire affected soils under Erica scrubs or meadows were found to be more active in carbon preservation potential.

The Northern Forest spans New York and three New England states and contains over 26 million ac, making it the largest contiguous forest east of the Mississippi. Most of the forestland is privately owned and public access to private land is a time-honored tradition in the region. Residents fear this tradition of open access may be threatened by recent acceleration in land tenure change across the region. We surveyed those who own 1,000 ac or more in the four-state region and found that newer owners were not more likely to post their land.

Coral reefs are threatened globally by the climatic consequences of rising atmospheric CO₂ levels; in many regions they are also threatened locally, for example, by reductions in the water quality of runoff from adjacent catchments. Interaction between global and local pressures makes it possible to use local actions to mitigate the impacts of climate change. To this end, managers and policy-makers are seeking to implement agricultural land management regimes that improve runoff water quality and thereby reduce risks to the Great Barrier Reef.

Restoring natural forests after field abandonment is a land management objective that fosters the recovery of forest biodiversity. We performed seeding and transplanting of native tree species 40 years after the abandonment of an arable field that became dominated by a dwarf bamboo (Pleioblastus chino (Franch. et Sav.) Makino) and by kudzu (Pueraria lobata (Willd.) Ohwi). By permutation tests, the removal of competing vegetation (gap creation) significantly increased the survival of three seeded species of Fagaceae and of eight transplanted species.

Efficient land use plays an important role in the context of sustainable agricultural development. Assuming that it will be viable only in cases when individuals employed in agriculture can ensure themselves an income equivalent and not less than the average wage in the national economy. Certain sizes of agricultural area, which are different for every key agricultural sector, are required to achieve it.

Determining appropriate topics and target audiences is essential to design effective educational outreach programs. Based on landowner responses to a mail survey, we determined both the importance and the availability of wildlife and forest management information topics to Mississippi landowners. Combining this information clearly identified the appropriate subject matter for outreach programs-topics important to landowners and for which information was relatively unavailable.

This article discusses the origins of natural ecosystem patterns from global to local scales. It describes how understanding these patterns can help scientists and managers in two ways. First, the local systems are shown within the context of larger systems. This perspective can be applied in assessing the connections between action at one scale and effect at another, the spatial transferability of models, and the links between terrestrial and aquatic systems. Second, scientists and managers can benefit because they gain information about the geographic patterns in ecosystems.

Changes in climate and land management practices in the San Pedro River basin have altered the vegetation patterns and dynamics. Therefore, there is a need to map the spatial and temporal distribution of the vegetation community in order to understand how climate and human activities affect the ecosystem in the arid and semi-arid region. Remote sensing provides a means to derive vegetation properties such as fractional green vegetation cover (fc) and green leaf area index (GLAI).

This paper analyses some key findings emerged in the study of the Mayan community of S. Jos Sinach, located in the Guatemalan Highlands. The research highlights how colonial and post-colonial legislation influences the actual land tenure and hampers the development of the community. Little land ownership together with high demographic growth lead to insufficient crop production. As a consequence, human pressure on S. Jos forest and seasonal migration to sugar cane plantations of the Pacific Coast is carried out by householders in order to ensure subsistence to their families.

The most widely applied soil carbon models partition the soil organic carbon into two or more kinetically defined conceptual pools. The initial distribution of soil organic matter between these pools influences the simulations. Like many other soil organic carbon models, the DAYCENT model is initialised by assuming equilibrium at the beginning of the simulation.
