Evaluation of the Pinus taeda quality using ultrasound [PDF]
2013 IEEE International Ultrasonics Symposium (IUS), 2013 The pinus is a type of wood that is widely used as feedstock for the production of softwood pulp and higher quality paper, boards, MDF (Medium Density Fiberboard), OSB (Oriented Standard Board), plywood, furniture and others. The main problem for the pinus is the attack by the wood wasps (Sirex noctilio F., 1793) (Hymenoptera; Siricidae) that damages ...

Responses of Seeds of Pinus taeda & P. strobus to Light [PDF]
Plant Physiology, 1962 Seeds of loblolly pine, Pinus taeda L., and of white pine, P. strobtus L., which require a long moist treatment at a low temperature (stratification) for complete germination, were chosen for this study. Seeds of the former species require 30 to 90 days at 2 to 3 C and those of the latter 30 days at 10 C or 60 days at 4 C (27).

Wildlife Letters, EarlyView.We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.
