We used an established seagrass monitoring programme to examine the short and longer-term impacts of an oil spill event on intertidal seagrass meadows. Results for potentially impacted seagrass areas were compared with existing monitoring data and with control seagrass meadows located outside of the oil spill area. Seagrass meadows were not significantly affected by the oil spill. Declines in s...

The response of montane and subalpine hay meadow plant and arthropod communities to the application of liquid manure and aerial irrigation - two novel, rapidly spreading management practices - remains poorly understood, which hampers the formulation of best practice management recommendations for both hay production and biodiversity preservation. In these nutrient-poor mountain grasslands, a mo...

Posidonia oceanica is an endemic seagrass species in the Mediterranean Sea. Due to its ecological importance, it has been the subject of several genetic studies aimed at increasing general knowledge of the system and helping to define appropriate management strategies. We compared the efficiency of 2 different classes of molecular markers, ‘inter simple sequence repeats’ (ISSRs) and ‘simple seq...

Bermuda is an isolated 5560 ha chain of limestone islands on a 150 000 ha seamount located near 32° N, 64° W. Meadows of tropical and subtropical seagrasses, dominated by Thalassia testudinum and Syringodium filiforme, are found from inshore bays out to the inner edge of the rim reef that encircles the platform. Fine-scale computerized mapping and subsequent broad-scaled field assessment of sea...

Alpine ecosystems are quite sensitive to global climatic changes. Drawing from two sets of remote sensing data (1986 and 2000) and field investigations, the ecological index method was used to document ecosystem changes in the Yangtze and Yellow River source regions of central Qinghai–Tibet. Although crucial to understanding alpine ecosystem responses to global climatic changes, and in assessin...

The regional hydrology and ecosystems of the northeastern margin of the Qinghai–Tibetan Plateau have changed over the past 40 years driven by intense human activity and regional climate changes. Annual mean air temperature has increased in the region. Streamflow from the northeastern margin of the Qinghai–Tibetan Plateau has decreased significantly. Overall, a number of Alpine step meadows and ...

Abstract Human interventions have had unintended consequences for the diverse functions of various ecosystems. Hydrological potential to alter vegetated habitats in coastal nearshore ecosystems, but little is known about impacts on organic carbon (C org ) sequestration, which plays an important role climate change mitigation. We examined effects past human through artificial inlet opening a lag...

The seagrass ecosystems found in the marine and coastal areas, with substantial eco-nomic ecological services span all over globe excluding Antarctic region. Coral Triangle Southeast Asia are recognized as a worldwide hotspot of species habitats, encompassing 10-21 every na-tion, although study, understanding, quantity publications on eco-systems rather limited region, including Malaysia. Malay...

Climate change models are predicting increased frequency and severity of droughts in arid and semiarid environments, and these areas are responsible for much of the world's livestock production. Because cattle (Bos Taurus) grazing can impact the abundance, distribution, and ecological function of native plant and animal communities, it is important to understand how cattle might respond to incr...
