WATER RELATIONS OF POCOSIN OR BOG SHRUBS

Water Relations of Pocosin or Bog Shrubs.

The pocosins, or broad-leaved evergreen shrub bogs, constitute one of the most distinctive plant communities of the southeastern coastal plain. They occupy flat, poorly-drained areas where the soil is frequently water-logged for long periods of time, but where surface water seldom stands to a depth of more than a few inches, and then only for comparatively short periods. The water relations of ...

Pocosin – Peatland and pocosin communities of the Coastal Plain include low pocosin, high pocosin, pond pine woodlands, peatla

EVects of nutrient addition on leaf chemistry, morphology, and photosynthetic capacity of three bog shrubs

Plants in nutrient-poor environments typically have low foliar nitrogen (N) concentrations, long-lived tissues with leaf traits designed to use nutrients eYciently, and low rates of photosynthesis. We postulated that increasing N availability due to atmospheric deposition would increase photosynthetic capacity, foliar N, and speciWc leaf area (SLA) of bog shrubs. We measured photosynthesis, fol...

Do fluctuating water levels alter nest survivorship in reservoir shrubs?

Reservoirs often have highly fluctuating water levels. The perimeters of these impoundments, which alternate between being exposed or inundated by water (drawdown zone), are used by nesting birds, but at the risk of nest submergence when water levels rise. For species that nest above the ground in shrubs, foraging and predation may also be affected by flooded habitat. Our objective was to clari...
