The startling warming of the Arctic is driving important environmental changes, but vegetation responses have been spatially heterogeneous and difficult to predict. In this context, establishing new ecological baselines initiating monitoring schemes are essential. We conducted systematic plot-based surveys in polar desert surrounding Alert (Nunavut, Canada). aimed at (1) identifying distinct pl...

The vegetation of Campbell Island and its offshore islets was sampled quantitatively at 140 sites. Data from the 134 sites with more than one vascular plant species were subjected to multivariate analysis. Out of a total of 140 indigenous and widespread adventive species known from the island group, 124 vascular species were recorded; 85 non-vascular cryptogams or species aggregates play a majo...

Alpine ecosystems harbor remarkably diverse and distinct plant communities that are characteristically limited to harsh, cold climatic conditions. As a result of thermal limitation species occurrence, mountainous considered be particularly sensitive climate change. Our understanding the impact change is mainly based on vascular plants however, whereas cryptogams (i.e., lichens bryophytes) gener...

Antarctic terrestrial ecosystems experience some of the most extreme growth conditions on Earth and are characterised by extreme aridity and sub-zero temperatures. Antarctic vegetation is therefore at the physiological limits of survival and, as a consequence, even slight changes to growth conditions are likely to have a large impact, rendering Antarctic terrestrial communities sensitive to cli...

1. Climate change in the subarctic is expected to influence vegetation composition, specifically bryophyte and lichen communities, thereby modifying litter decomposition rates and carbon (C) dynamics of these systems with possible feedbacks to climate. 2. In a two-year experiment, we investigated decomposition rates and chemical traits of 27 bryophytes, 17 lichens and 5 vascular plants in litte...

Abstract A common view is that honeybees are mostly managed by beekeepers for commercial purposes or as a hobby, especially in Europe. This misconception probably due to the lack of systematic studies on wild colonies Europe comparison other regions world. Since we used considering this species “domesticated”, may be induced disregard activities not distinctly linked with colony survival, repro...
