Research in tropical forestry is confronted with the task of finding strategies to alleviate pressure on remaining forests, and techniques to enhance forest regeneration and restore abandoned lands, using productive alternatives that can be attractive to local human populations. In addition, sustainable forestry in tropical countries must be supported by adequate policies to promote and maintain specific activities at local and regional scales.
The last three rows demonstrated the crucial counterintuitive prediction that
small prey would be excluded from the diet, independently of their encounter
rate, if the encounter rate with large prey were above a certain quantifiable
Those were heady days! Setting aside the fact that the small prey were not
totally ignored, it seemed as though a very simple, testable model, derived from
a few starting assumptions about rate maximization and constraints on foraging,
could actually predicthowan animal responded in an experiment. It’s hard
to overstate the excitement at the time....
13 Foraging and the Ecology of Fear
The reintroduction of wolves in 1995 changed Yellowstone National Park. Riparian habitats have seen a marked increase in willows and aspen. The streams running through these willow thickets meander more. Wetlands have reappeared.
Reducing consumption is the key to bringing down our Ecological Footprint. There is a link
between cities that have the biggest disposable incomes and the cities with the biggest footprints
The link is not an automatic one: some well-off cities have a footprint that is smaller than might
be expected. Salisbury has a one of the lowest footprints in the UK but high house prices and
