Plant communities in northern Quebec-Labrador, Canada have been severely grazed and trampled since the early 1980s by the increasingly large George River caribou herd (GRCH). To evaluate changes in species dominance associated with caribou disturbance, we compared past and present ground vegetation from 14 lichen woodlands. Plant remains from superficial organic horizons indicate that ground ve...

South African savanna grasslands are often characterised by indigestible tufted grass species whereas lawn grasses are far more desirable in terms of herbivore sustenance. We aimed to investigate the role of nutrients and/or the disturbance (grazing, trampling) by herbivores on the formation of grazing lawns. We conducted a series of common garden experiments to test the effect of nutrients on ...

Alpine grassland ecosystem supports high diversity of terrestrial flora and fauna species. Despite the ecological importance economic potential this unique type, it experiences increasing anthropogenic disturbances such as trampling, which impose negative impact on health integrity alpine grasslands. Previous studies trampling vegetation mainly focus changes in cover taxonomic after disturbance...

The impacts of fragmentation and recreational use on the hemiboreal urban forest understorey vegetation and the microbial community of the humus layer (the phospholipid fatty acid (PLFA) pattern, microbial biomass and microbial activity, measured as basal respiration) were examined in the greater Helsinki area, southern Finland. Trampling tolerance of 1) herb-rich OMT, 2) mesic MT, and 3) sub-x...

ure from Greek mythology for nearly 3 millennia. Central to his myth is the story cycle about the 12 presumably impossible labors he carried out for the loathed King Eurystheus. Sometimes overlooked is that Hercules performed those tasks as penance for having murdered his own wife and children during a fit of madness. For the fourth labor, Eurystheus ordered Hercules to capture the vicious Erym...

Balancing increasing recreation demand with nature conservation objectives in Australia’s protected areas provides a difficultchallenge for land managers.This paper summarises the evidence of biophysical impacts of horse riding and highlights the important differences between Australian environments and those elsewhere.Unique environmental conditions in Australia make conservation lands in Aust...
