Primeros resultados sobre variaciones del ambiente lumínico en el seno de varias comunidades vegetales
1988
Se caracterizan y tipifican 4 modelos de iluminación en el seno de comunidades vegetales pertenecientes a la serie reconstitutiva del encinar termófilo valenciano, Rubio longifoliae - Quercetum rotundifoliae Costa, Peris & Figuerola 1982. valenciano, Rubio longifoliae - Quercetum rotundifoliae Costa, Peris & Figuerola 1982. Para ello se analizan los niveles de rediación fotosintéticamente activa bajo cubierta de coníferas (pinus halepensis Miller), lauroides (Arbutus unedo L. y Viburnum tinus L.), frondosas perennifolias (Quercus rotundifolia Lam) y la combinación de grandes arbustos perennifolios (Pistacia lentiscus L.) y frondosas caducifolias (Fraxinus ornus L.) a 4 alturas de toma de da…
The role of power line rights-of-way as an alternative habitat for declined mire butterflies
2011
Habitat loss is one of the greatest threats for biodiversity. In Finland, two thirds of natural mires have been drained for silviculture, which transforms open wetlands into dense forests. However, vegetation management of power line rights-of-way (ROW) maintain the drained mires as open areas. The aim of this study was to determine the effect of the power line ROW vegetation management on butterfly abundance, species richness and community structure by comparing the managed power line ROWs to unmanaged drained control sites and to natural mires. The species richness or abundance of mire butterflies did not differ between the power line ROWs and natural mires. In contrast, both species rich…
