Does a trade?off between growth plasticity and resource conservatism mediate post?fire shrubland responses to rainfall seasonality?

چکیده
Growth plasticity may allow fire-prone species to maximize their recovery rates during temporary, sporadic periods of rainfall availability in the post-fire environment. However, moisture-driven growth could be maladaptive nutrient-limited environments that require tighter control and resource use. We investigated whether a trade-off between conservatism mediates responses altered seasonality neighbouring shrubland communities occupy different soils. monitored vegetation regrowth two structurally similar, Mediterranean-type shrublands for 3 years. effects experimentally on species’ rates. found was higher among occupying fertile soils renosterveld site relative those nutrient-poor fynbos site.

Modifying rainfall patterns in a Mediterranean shrubland: system design, plant responses, and experimental burning.
Global warming is projected to increase the frequency and intensity of droughts in the Mediterranean region, as well as the occurrence of large fires. Understanding the interactions between drought, fire and plant responses is therefore important. In this study, we present an experiment in which rainfall patterns were modified to simulate various levels of drought in a Mediterranean shrubland o...
متن کاملCell-specific nitrogen responses mediate developmental plasticity.
The organs of multicellular species consist of cell types that must function together to perform specific tasks. One critical organ function is responding to internal or external change. Some cell-specific responses to changes in environmental conditions are known, but the scale of cell-specific responses within an entire organ as it perceives an environmental flux has not been well characteriz...
متن کاملRainfall Seasonality and the Spread of Millet Cultivation in Eurasia
Broomcorn millet (Panicum miliaceum) was known throughout Eurasia in the second millennium BC in regions with warm, moist summers, where its cultivation reduced agricultural risk. Its cultivation during the warm, but dry months at Kyzyltepa and other Iron Age sites in western Central Asia was probably made possible through irrigation practices that were long known and originally developed in th...
متن کاملNegative correlation does not imply a tradeoff between growth and reproduction in California oaks.
A tradeoff between growth and reproduction, often inferred from an inverse correlation between these two variables, is a fundamental paradigm of life-history evolution. Oak species provide a unique test of this relationship because different species mature acorns either in the year of pollination or in the year after pollination. This difference allows for an interspecific comparison testing wh...
