[MCN] The advantage of being little

[Lance Olsen]

"The predictors of risk were significantly 
different for smaller and larger species, with 
the importance of many predictors changing 
markedly at a body size of 3 kg. Species smaller 
than this fit the firing-line model: Š. Larger 
species, however, face multiple jeopardy: Š."

"Perhaps the most obvious proposed risk factor 
for extinction is large body size."

biodiversity. Proceedings of the National Academy 
of Sciences, Aug. 12, 2008.

"Of more than 150 genera of megafauna -- that is, 
animals weighing more than 44 kilograms (97 
pounds) -- living on Earth 50,000 years ago, at 
least 97 were extinct by 10,000 years ago.  If 
you look at localized extinctions instead of 
global extinctions, 121 genera disappeared from 
at least one continent."

"'One thing we can do, as conservationists, is to 
create and connect natural areas' to allow 
animals to move around, he added."

"Here we discuss the capacity of conservation 
organizations to adapt to changing environmental 
conditions, focusing primarily on public agencies 
and nonprofits active in land protection and 
management in the US. After first reviewing how 
these organizations anticipate and detect impacts 
affecting target species and ecosystems, we then 
discuss whether they are sufficiently flexible to 
prepare and respond by re-allocating funding, 
staff, or other resources. We raise new 
hypotheses about how the configuration of 
different organizations enables them to protect 
particular conservation targets and manage for 
particular biophysical changes that require 
coordinated management actions over different 
spatial and temporal scales. Finally, we provide 
a discussion resource to help conservation 
organizations assess their capacity to adapt."

"In order to jointly provide desired levels of 
urban land, food production, and ecosystem 
service and species habitat provision, the global 
society will have to become much more strategic 
in its allocation of intensively managed land 
uses."
