Successful fire exclusion in the 20th century has created severe fire problems across the West. Not every forest is at risk of
uncharacteristically severe wildfire, but drier forests are in need of active management to mitigate fire hazard. We summarize a
set of simple principles important to address in fuel...

Leucopis spp. (Diptera: Chamaemyiidae) from the Pacific Northwest previously were identified as potential biological control agents for the hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), in the eastern United States. We collected Leucopis spp. larvae from A. tsugae infested western hemlocks in Oregon and Washington and reared them on...
Foraging honey bees (Apis mellifera L.), exposed to birdsfoot trefoil (Lotus corniculatus L.) bloom treated with microencapsulated methyl parathion, continued to display pollen and midgut microcapsule contamination up to 9 days postspray. Nearly 10% of all pollen storage cells examined in combs taken from honey bee colonies exposed to the...
Caribbean coral reefs have deteriorated substantially over the past 30 years, which is broadly attributable to the effects of global climate change. In the same time, Indo-Pacific reefs maintain higher coral cover and typically recover rapidly after disturbances. This difference in reef resilience is largely due to much higher coral...
Objectives of proposed research:
1. Investigate the relationship between abscisic acid (ABA) and auxins and the regulation of carbon partitioning.
2. Investigate the origin of ABA present in the fruit during ripening and attempt to modify the partitioning pattern through manipulation of endogenous ABA levels using mefluidide (ABA biosynthesis promoter)...
Because of the intangible nature of online shopping, consumers perceive online shopping as being risky. This study examined how this risk can be reduced specifically by using a more effective online product presentation method. A combination of the number of product views (one and four) and size (small and large)...
We propose a mathematical formulation for strategic relay network design and dispatching method selection for full truckload transportation. The proposed model minimizes total transportation and installation costs of a mixed fleet dispatching system combining relay network and point-to-point dispatching. Operational constraints such as maximum driver tour length and load circuity...
Donato et al. (Brevia, 20 January 2006, p. 352) concluded that logging after wildfire kills natural
regeneration and increases fire risk. We argue that their paper lacks adequate context and
supporting information to be clearly interpreted by scientists, resource managers, policy-makers,
and the public.
Ceratomyxa shasta is a myxozoan parasite identified as a contributor to salmon mortality in the Klamath River, USA. The parasite has a complex life cycle involving a freshwater polychaete, Manayunkia speciosa and a salmonid. As part of ongoing research on how environmental parameters influence parasite establishment and replication, we designed...
