Water channel proteins, aquaporins, play fundamental roles in transmembrane water movements in plants. A new full-length cDNA encoding aquaporin was isolated from the seedlings of Jatropha curcas. The gene of the plasma membrane intrinsic protein (PIP) from J. curcas (JcPIP2) contained an 843 bp open reading frame encoding a protein of 280 amino acids. The amino acid sequence showed 94% identit...

—Northern white cedar (Thuja occidentalis L.) stands throughout the upper Midwestern United States have failed to recruit individuals to the canopy consistently for several decades. To examine local and landscape factors that influence cedar regeneration we recorded the abundance of cedar seedlings and saplings in 24 lowland cedar stands in the Chequamegon-Nicolet National Forest, Wisconsin, du...

Low water availability reduces the establishment of the invasive shrub Prosopis on some grasslands. Water deficit survival and traits that may contribute to the postponement or tolerance of plant dehydration were measured on seedlings of P. glandulosa Torr. var. glandulosa (honey mesquite) grown at CO(2) concentrations of 370 (ambient), 710, and 1050 micro mol mol(-1). Because elevated CO(2) de...

Fire is a major disturbance factor influencing the formation and maintenance of oak (Quercus)-dominated forests of eastern North America. Fire suppression practices have resulted in declining oak dominance, and caused the loss of oak seedlings due to poor light regimes and vegetative competition. Both wildfires and prescribed fires can alter forest stand composition and influence succession. Fi...

Cryphalus asperatus (Coleoptera: Curculionidae, Scolytinae) is described as an exceptional but important secondary pest of Norway spruce seedlings. Of the 10 000 seedlings transported to one location in Ore Mountains, Central Europe 2020, total 1 500 were killed by C. asperatus. The infestation and death probably resulted part from substantial local increase abundance after sanitation felling m...
