Pattern and control of primary production

Plant growth in most ecosystems forms the base or “primary” component of the food web. The amount and type of plant growth in an ecosystem helps to determine the amount and kind of animals (or “secondary” productivity) that can survive there.

How does precipitation control primary production at Jornada Basin LTER?

Poster Number:  18 Presenter/Primary Author:  Jin Yao This study tested two hypotheses regarding pattern and control of aboveground net primary production (ANPP) in the Chihuahuan Desert, with emphases on seasonality and plant functional group.

Evidence for multiple pathways in old field succession?

Poster Number:  12 Presenter/Primary Author:  Adam Clark A rich body of theoretical and experimental literature suggests that differences in species assembly order, and manipulation of environmental factors such as nutrient availability, can fundamentall

Long-term forb dynamics in semi-arid grasslands of the northern Chihuahuan Desert, New Mexico, USA.

Poster Number:  10 Presenter/Primary Author:  John Mulhouse Perennial grasses and shrubs have been well-studied in semi-arid grasslands, but relatively little is known about the forb community.  We analyzed a twenty-two-year dataset (1989-2010) from th

Effects of interannual precipitation variability on aboveground net primary production in the Chihuahuan desert

Poster Number:  6 Presenter/Primary Author:  Laureano Gherardi Climate change will result not only in changes in the mean climate state but also in the variability of climate.
