Screening of decabromodiphenyl ethane (dbdpe) in lake sediment, marine sediment and peregrine falcon eggs
In general terms, BFRs are a controversial group of chemicals. Flame retardants protect lives by increasing fire safety, but at the same time, several of the BFRs are regarded as concerning environmental contaminants. These include polybrominated diphenyl ethers (PBDEs), tetrabromobisphenol A (TBBPA) and hexabromocyclododecane (HBCD). The reasons for concern about BFRs are observed or suspected...
متن کاملPeregrine Falcon Eggs: Egg Size, Hatchling Sex, and Clutch Sex Ratios
Eggs (n = 367) collected from wild Peregrine Falcon (Falco peregrinus anatum) nests between 1976 and 1990 in Colorado and New Mexico were artificially incubated and hatched. We retrospectively examined these data for variation in egg length, breadth, and initial mass of hatchlings to resolve questions about relationships among egg size, chick size, and sex; and egg size related to first and sec...
متن کاملModeling and Control of the Peregrine Falcon Population
Peregrine falcons were recently removed from the endangered species list and there is a desire to harvest these birds for sport. The US Fish and Wildlife Service currently allows minimal harvesting in parts of the country. However, the question is how many can be extracted from the population before the future population will go into decline. My research utilizes a population projection matrix ...
متن کاملDiving-Flight Aerodynamics of a Peregrine Falcon (Falco peregrinus)
This study investigates the aerodynamics of the falcon Falco peregrinus while diving. During a dive peregrines can reach velocities of more than 320 km h⁻¹. Unfortunately, in freely roaming falcons, these high velocities prohibit a precise determination of flight parameters such as velocity and acceleration as well as body shape and wing contour. Therefore, individual F. peregrinus were trained...
متن کاملOrganochlorine pesticides, PCBs, dioxins, and metals in postterm peregrine falcon (Falco peregrinus) eggs from the Mid-Atlantic states, 1993-1999.
Peregrine falcons were extirpated from the eastern United States by 1964 due to the effects of dichloro-diphenyl-trichlorethane (DDT) (Peakall and Kiff 1988). As a result of restoration efforts, peregrines have largely recovered in the region but remain a barometer of environmental contamination. In the course of monitoring nests, biologists in the mid-Atlantic states collected peregrine falcon...
