Never mind other priorities, such as the roads at Yellowstone National Park, where partial fixes, patches and overlays made with limited funding have left some roads treacherous.
Both habitat destruction (in the sense of destruction of entire patches) and habitat deterioration (in the sense of partial destruction of patches) lower the metapopulation capacity of the patch network.
Crucial for our results is the partial depletion of patches, because (i) it leads to a structured environment with many partially depleted patches of different size, and (ii) this allows grouping to "find its niche".
When, as a teacher, I left behind the well-traveled ways of traditional explanatory instructions, I found myself, together with my students, in a wild landscape of misconceptions, partial truths, and patches of " terra incognita".
They found that, contrary to the conventional view of dominance of severe stand-replacing disturbances in the boreal forest, gap, patch and partial disturbances were most commonly reported in the research literature.
The underside of the abdomen is black and has a red patch or partial red hourglass-shaped marking.
Management options we examined were: (1) the status quo, (2) varying the total annual timber harvest on the landscape (100%, 80% or 50% of current long-term sustained yield estimates), (3) the protection of understory trees during logging, and (4) 30 70% retention of overstory (partial cutting in distinct patches <1 ha in size) in each harvest unit, for 33% or 50% of the annual timber harvest.
Under high light, acidification of lumen, which is known to trigger VDE activity, will result in partial neutralization of these patches and allow VDE access to the PSI-LHCI gap regions (Arnoux et al., 2009).
