In response to the unprecedented spread of bark beetles in the Rocky Mountains and other parts of the western United States, the U.S. Forest Service formed the Western Bark Beetle Research Group (WBBRG) in 2007—a collaboration between scientists from three research stations that pools knowledge and resources to better understand the threat and eventually develop a strategy to combat it.

Phloeosinus serratus, the juniper bark beetle, is a species of crenulate bark beetle in the family Curculionidae. It is found in North America. [1] [2] [3] References
Bark beetles enter trees by boring holes in the bark of the tree, sometimes using the lenticels, or the pores plants use for gas exchange, to pass through the bark of the tree. [3] As the larvae consume the inner tissues of the tree, they often consume enough of the phloem to girdle the tree, cutting off the spread of water and nutrients.
The beetle is capable of flying up to 24 km (15 mi), and has strong dispersal capabilities and ability to locate its host trees. In the Czech Republic, it is typically found in the common juniper, Juniperus communis, and it is considered to be a threat to that species, which is near-threatened. [2] P. aubei has several natural parasites.

Biological control agents of weeds include seed predators, herbivores, and plant pathogens. Biological control can have side-effects on biodiversity through attacks on non-target species by any of the above mechanisms, especially when a species is introduced without a thorough understanding of the possible consequences.
Pork tenderloin, also called pork fillet, [1] pork steak [2] or Gentleman's Cut, is a long, thin cut of pork. As with all (mammalian) quadrupeds , the tenderloin refers to the psoas major muscle [ 3 ] along the central spine portion, ventral to the lumbar vertebrae, the most tender part of the animal, because those muscles are used for posture ...
