Why Huddle? Ecological Drivers of Chick Aggregations in Gentoo Penguins, Pygoscelis papua, across Latitudes
Aggregations of young animals are common in a range of endothermic and ectothermic species, yet the adaptive behavior may depend on social circumstance and local conditions. In penguins, many species form aggregations (aka. crèches) for a variety of purposes, whilst others have never been observed exhibiting this behavior. Those that do form aggregations do so for three known benefits: 1) reduc...
متن کاملPollution and physiological variability in gentoo penguins at two rookeries with different levels of human visitation
Human activity and specifically tourism has been increasing in Antarctica over the last few years. Few studies have examined the indirect effects of human visits on Antarctic penguin rookeries. This work aims to study the differences between a highly visited (Hannah Point) and a rarely visited (Devil’s Point, Byers Peninsula) gentoo penguin rookery on Livingston Island. Our results suggest that...
متن کاملApproach to Occupational Cases of Lead Poisoning
Introduction: Lead is a toxic metal that is found in the earth's crust and has been used by humans since 7000 years ago due to its density, malleability, high resistance and low melting point. The wide use of this metal in the industry, in addition to the exposure of workers, has led to widespread environmental pollution and public health problems in many parts of the world. Due to the widespre...
متن کاملFeathers as a Tool to Assess Mercury Contamination in Gentoo Penguins: Variations at the Individual Level
Feathers have been widely used to assess mercury contamination in birds as they reflect metal concentrations accumulated between successive moult periods: they are also easy to sample and have minimum impact on the study birds. Moult is considered the major pathway for mercury excretion in seabirds. Penguins are widely believed to undergo a complete, annual moult during which they do not feed. ...
متن کامل[Lead poisoning in children].
In October 1991, the Centers for Disease Control issued new recommendations lowering the acceptable blood lead level. This change was based on data indicating that irreversible adverse neurodevelopmental effects occur in children with chronic low-level exposure to lead. The primary source of lead poisoning is still lead-based paint, particularly in older urban housing. Other sources of lead poi...
