Ancient woodland

10.5 Alternative possible changes in species richness of saproxylic biota dependent on Coarse Woody Debris (CWD) in a forest stand after initial colonization of tree-less ground. Large amounts of dead wood are characteristic of old-growth forests (Kirby et al., 1991). Microhabitat formation here means the time needed to create 'equilibrium levels', at which input rate and decay rate of CWD (bold line) are in balance in the stand. Alternative scenarios are possible. (A) Here the geographical...

Ethical foundation for insect conservation

We may notice . . . that the tree-hopper, called by the Greeks Tettix, by the latins Cicada, received also from the former the title of Earth-born, - a title lofty in its lowliness, because it was an implied acknowledgment from men of Athens and of Arcady of a common origin with themselves - an admission that the insect was their brother, sprung (as they fabled) from the earth, their common parent, -- whence, also, they wore golden tree-hoppers in their hair. Conservation action must have a...

Insects and the conservation of ecosystem processes

But in an African forest not a fallen branch is seen. One is struck at first at a certain clean look about the great forests of the interior, a novel and unaccountable cleanness, as if the forest-bed was carefully swept and dusted daily by unseen elves. And so, indeed, it is. Scavengers of a hundred kinds remove decaying animal matter - from the carcase of a fallen elephant to the broken wing of a gnat - eating it, or carrying it out of sight, and burying it on the deodorising earth....
