Ecosystem responses to key climate drivers are reflected in phenological dynamics such as the timing and degree of "green-up" that integrate responses over spatial scales from individual plants to ecosystems. This integration is clearest in ecosystems dominated by a single species or life form, such as seasonally dynamic grasslands or more temporally constant evergreen forests. Yet many ecosyst...

An ecologically sound approach to the problem of brush encroachment onto Israeli rangeland might be their utilization by goats, but better knowledge of the feeding selectivity and ability of goats to thrive in encroached areas is required to devise viable production systems. Direct observation of bites could provide precise and accurate estimates of diet selection, but construction of a suffici...

Tiarks, A.E. and Haywood, J.D., 1986. Pinw taeda L. response to fertilization, herbaceous plant control, and woody plant control. For. Ecol. Manage., 14 : 103-1 12. On an intensively prepared site, a complete fertilizer applied at planting, and control of herbaceous and woody plants for the first 4 years, increased Pinus taeda L. volume at age 5 to 25.9 m3/ha compared t o 11.8 m3/ha without the...

Woody plant encroachment is an ongoing global issue. In the Southern Great Plains of United States, rapid and coalescence woody plants are transforming herbaceous-dominated rangelands into woodlands with a detrimental impact on water quality quantity. this study, we conducted modeling simulations to assess how converting juniper (Juniperus virginiana) woodland low moderately productive grasslan...

About 21% of the African population directly depends on rangeland resources. As this number is predicted to grow, it important understand response rangelands global environmental change and formulate, in turn, better hypotheses their capacity support livelihoods. Here we used three decades satellite data a dynamic vegetation model study recent climate describe changes structure accompanying gre...

Rain-index insurance is strongly advocated in many parts of the developing world to help farmers to cope with climatic risk that prevail in (semi-)arid rangelands due to low and highly uncertain rainfall. We present a modeling analysis of how the availability of rain-index insurance affects the sustainability of rangeland management. We show that a rain-index insurance with frequent payoffs, i....

Adapting what we currently know about ecosystems to a future where rangelands are changing is a new frontier in rangeland management. Current tools for knowledge discovery and application are limited because they cannot adequately judge ecological relevance of knowledge to specific situations. We propose development of integrated knowledge systems (KSs)— collections of resources (e.g., data, an...
