To elucidate the relationship between diapause and cold hardiness in the oriental corn borer, Ostrinia furnacalis, the levels of various substances, cold hardiness and respiration were measured in diapausing and post-diapausing overwintering larvae. Under field conditions, diapause terminated between November and January, although O(2) consumption, measured at 20 degrees C in the laboratory, re...

Understanding local adaptation of tree populations to climate allows the development of assisted migration guidelines as a tool for forest managers to address climate change. Here, we study the relationship among climate, a wide range of physiological traits, and field performance of selected white spruce provenances originating from throughout the species range. Tree height, survival, cold har...

We investigated changes in photochemical activity and cold hardiness of detached needles of three clones of Picea abies (L.) Karst. by measuring variable chlorophyll fluorescence (F(v)/F(m)), before and after artificial freezing, from September to June. Photochemical activity varied considerably during the study, but only minor differences in photochemical activity among the clones were observe...

In 1989, identical crosses (2-3 females within males) were performed with Picea abies (L.) Karst. in a greenhouse seed orchard at Biri nursery and in an outdoor seed orchard at Huse, 32 km north of Biri. Pollination began 17 days earlier in the greenhouse than outdoors at Huse. The potted grafts in the greenhouse were moved outdoors when the seed cones were no longer receptive. Twelve full-sib ...

The hemlock woolly adelgid (HWA), Adelges tsugae Annand, primarily infests trees along the eastern seaboard in USDA plant hardiness zones where the minimum low temperature does not exceed –28.8°C. Laboratory studies were done to determine the low lethal temperature of HWA collected in January, February, and March from locations within different USDA plant hardiness zones. The Mt. Tom, Massachus...

Young Black gay/bisexual men (YBGBM) are affected by contextual stressors-namely syndemic conditions and minority stress-that threaten their health and well-being. Resilience is a process through which YBGBM achieve positive psychosocial outcomes in the face of adverse conditions. Self-efficacy, hardiness and adaptive coping, and social support may be important resilience factors for YBGBM. Thi...
