Abstract OCBIL theory aims to develop hypotheses that explain the evolutionary ecology of biota on old, climatically buffered, infertile landscapes (OCBILs). The table mountain OCBILs Guayana Highlands are a major centre Neotropical plant diversity; however, knowledge about underlying mechanisms community assembly at mountaintops is still limited. We evaluated effect fine-scale geoenvironmental gradient phylogenetic metrics communities iconic, highly isolated Roraima Highlands. selected...
Unidades de conservação representam a principal estratégia para preservação e recuperação recursos naturais brasileiros. Para nortear o seu planejamento gestão, informações relativas aos geoambientes constituem um referencial integrado indispensável. O objetivo deste estudo foi descrever os aspectos pedológicos associados à identificação, caracterização mapeamento do Parque Nacional Serra da Mocidade, Roraima, norte Brasil, forma subsidiar manejo ecológico unidade. estratificação...
<title>Abstract</title> Little is known about the role of guano from quartzite caves in forming biodiverse plant communities surrounding areas due to direct or indirect nutrient and energy inputs. This study investigates four Quartzite Endokarst Ibitipoca State Park (PEI), Brazil, by analyzing surface soils cave interior forests. We evaluated following hypotheses: (i) deposits modify floor influence external communities; (ii) there a gradient its surroundings, linked deposition...
The Guayana Highlands (GH) represents a major center of Neotropical plant diversity and endemism. Considering the lack information about ecology communities in this region, we analyzed fine-scale pattern vegetation diversity. Thus, tested effects abiotic filters (i.e. soil physicochemical properties depth) on species richness community composition complex rocky outcrop landscapes at Roraima table mountain summit. This tepui is located triple boundary shared by Brazil, Venezuela Guyana. A...
