Altering light in a bird's environment influences the onset of several eye conditions, including avian glaucoma and avian macrophthalmos
. In addition, birds exposed to continuous light can develop other serious health issues including leg disorders and stress, which can ultimately lead to premature death, says Hammed A.
Habitat overlap of Paralabrax humeralis (Cuvier & Valenciennes, 1828), Hemilutjanus macrophthalmos (Tschudi, 1845), and Acanthistius pictus (Tschudi, 1845) (Pisces; Serranidae) in the rocky subtidal south of Iquique, Chile.
The family Serranidae is represented by three species of sympatric predators (Paralabrax humeralis, Hemilutjanus macrophthalmos, Acanthistius pictus) along the coastal shore ecosystems off northern Chile (Chirichigno, 1974; Mann, 1954).
macrophthalmos use the habitat differently, presumably defined by the studied microhabitat categories.
macrophthalmos specimens observed were found between 10 and 15 m depth (Fig.
macrophthalmos) and cavity (< 0.5 m) specialists (A.
macrophthalmos have been caught along the entire continental shelf off northern Chile (Samame et al., 1978; Mendieta & Castillo, 1988; Velez et al., 1988; Espino, 1990).
macrophthalmos) also preferred soft bottom habitats, mostly sand on the floor of caves (> 0.5 m) and cavities (< 0.5 m).
