Extensive management is one of the methods used in conservation fen meadows. The aim study was to characterize grassland communities grazed by Konik horses Biebrza National Park and assess influence short-term grazing on sward. During a 3-year period, phytosociological studies, measurements sward cover height, as well an assessment botanical composition meadows were conducted places excluded fr...

Native meadows are widely used by producers in southeast Kansas. However, there few studies about management practices to improve agronomic performance This study evaluated the spring burn effect combined with application of lime, nitrogen, phosphorus, and potassium on yield forage quality native meadows. Yield were not affected lime application, or P K fertilization first year study. N increas...

Climate changes are affecting the fate of Posidonia oceanica meadows. Actually, Mediterranean Sea is threatened by abiotic, biotic and climate coupled with human pressures regarding coastal regions. In this way, able to counteract effects through high thermotolerance species, range shift processes meadows variations in community composition valuable marine ecosystem. Anyway, power acclimatizati...

Five species of polychaetes (Spionidae) were found associated to Thalassia testudinum meadows in Parque Nacional Morrocoy, Venezuela. We included a guide for their identification and present range extensions for the Venezuelan coasts and Southern Caribbean Sea. The species are: Dipolydora socialis, Prionospio (Minuspio) cirrifera, P. (Prionospio) fallax, P. (P.) steenstrupi, and Spio pettiboneae.

Seagrass ecosystems face widespread threat from reduced water quality, coastal development and poor land use. In recent decades, their distribution has declined rapidly, and in the British Isles, this loss is thought to have been extensive. Given increasing knowledge of how these ecosystems support fisheries production, the understanding of their potential rapid loss, and the difficulty in rest...

One hundred and fifty years since Charles Darwin first collected and surveyed the wildflowers and meadows of his family home, Down House — just 25 kilometres south of London — scientists from the Natural History Museum and conservationists from English Heritage have begun to retrace Darwin's footsteps by replicating his meticulous observations. In 1855 Darwin recorded 142 different plants in Gr...

To assess the effects of shading by epiphytes on the carbon balance of the seagrass Posidonia oceanica, we examined the patterns of within-shoot epiphyte abundance on leaves, and their variability with season and depth. Epiphyte biomass was found to depend on leaf age (larger epiphyte load on older tissues), leaf side (more epiphytes on the inner face than on the outer) and depth (more epiphyte...
