“…Of the NPP surveys carried out in the Pyrenees, only two deal with modern analogs. Ejarque et al (2011) analyzed highland's modern assemblages of pollen and NPP and found useful relationships with vegetation and environmental patterns, as well as with grazing activities. The study included samples from cattle excrements in order to identify potential grazing indicators.…”

Modern non-pollen palynomorphs sedimentation along an elevational gradient in the south-central Pyrenees (southwestern Europe) as a tool for Holocene paleoecological reconstruction

et al. 2014

Non-pollen palynomorphs (NPP) are microfossils other than pollen and spores from plants found within samples prepared for pollen analyses. Their utility as paleoecological indicators is rapidly growing because of their potential to complement palynological reconstructions of past communities and environments. The study of modern NPP sedimentation patterns using surface samples from different substrates, vegetation types and environmental conditions is needed to characterize the main environmental and anthropogenic factors involved in establishing ecological gradients. Here, we analyze modern NPP distribution along an elevational transect from the south-central Pyrenees. We use these data to test the potential influence of elevation, vegetation type, sampling sites and human disturbance on modern NPP distribution and to obtain a NPP modern-analog model which will enhance further paleoecological interpretations. Our study used the same surface samples obtained in a previous modern-analog palynological study, along an elevational transect from 870 to 2600 m a.s.l. We identified 55 NPP, including 13 unidentified morphotypes that were described and depicted. Individual NPP analysis and multivariate statistical methods showed that altitude plays a significant role in the NPP distribution along the transect but other factors such as soil moisture, landscape openness and grazing intensity also influenced the composition of NPP assemblages. Our results also recognized some characteristic NPP assemblages linked to elevational vegetation belts and individual NPP morphotypes related with specific microhabitats, both with potential paleoecological indicator capacity. This work is a first step to improve the knowledge of the NPP's indicator value in the study area.

“…Some studies have also been carried out in Scotland (Bunting, 2003), in England (Waller et al, 2005;Smith et al, 2010) and in arid environments in Spain (Carrion, 2002). However only few studies were interested in mountainous areas, such as the Pyrenees (Mazier, 2006;Cugny et al, 2010;Ejarque et al, 2011) and the French Alps (Court-Picon et al, 2005. Brun (2007Brun ( , 2011 suggested to redefine the anthropogenic pollen indicators in low mountain areas of Franche-Comté (Jura Mountains), but mainly focused on arable-weed and ruderal flora from lowlands (up to 700 m a.s.l.)…”

“…Although they bring a new interpretative dimension to palynological analysis without requiring more sampling and preparation (van Geel et al, 2003;Graf and Chmura, 2006), very few reconstructions of past vegetation and human activities combining both pollen indicators and NPPs have been carried out in mountainous areas (Mazier et al, 2009;Jouffroy-Bapicot, 2010;Ejarque et al, 2011). When regarding modern pollen spectra, NPPs are generally poorly considered; however, a few pioneer studies have investigated wetland, forested and/or mountain areas (CourtPicon et al, 2005;Barthelmes et al, 2006;Blackford and Innes, 2006;Prager et al, 2006;Cugny et al, 2010).…”
