Optimal avoidance and evasion tactics in predator-prey interactions
(Elsevier, 1984-01-21)
A kinematic analysis of optimal avoidance and evasion techniques for prey is presented. The analysis is mainly directed towards piscivorous interactions but can include other aquatic and terrestrial cases. Avoidance is ...
Combined effects of atmospheric CO 2 and N availability on the belowground carbon and nitrogen dynamics of aspen mesocosms
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-08)
It is uncertain whether elevated atmospheric CO 2 will increase C storage in terrestrial ecosystems without concomitant increases in plant access to N. Elevated CO 2 may alter microbial activities that regulate soil N ...
Soil respiration in northern forests exposed to elevated atmospheric carbon dioxide and ozone
(Springer-Verlag, 2006-02-18)
The aspen free-air CO 2 and O 3 enrichment (FACTS II–FACE) study in Rhinelander, Wisconsin, USA, is designed to understand the mechanisms by which young northern deciduous forest ecosystems respond to elevated atmospheric ...
Microclimatic changes and the indirect loss of ant diversity in a tropical agroecosystem
(Springer-Verlag, 1996-11)
Recent changes in the coffee agroecosystem of Costa Rica were used to study the mechanism of biodiversity loss in transforming agroecosystems, focusing on the ground-foraging ant community. Coffee farms are being transformed ...
