Appendix X: Year 1 results: feeding ecology of the introduced predatory snail Euglandina rosea Feeding ecology of the introduced predatory snail Euglandina rosea (Férussac) in Hawai‘i: implications for the preservation of native land snail species
Introduction The introduction of the land snail Euglandina rosea, which feeds exclusively on snails, has been implicated as a major factor influencing the decline of the native Hawaiian land snail fauna (Hadfield 1986). It was introduced to Hawaii in 1955 to control populations of another introduced snail, Achatina fulica, the giant African snail (Davis & Butler 1964, Simberloff 1995, Civeyrel ...
متن کاملEnergy utilization in newly hatched chicks.
The changes in body weight and composition were examined in broilers that either had immediate access to feed and water or had not been fed for 48 h posthatch. Chicks without access to feed decreased in BW by 7.8% in the 48 h posthatch, which was equivalent to 5.3 kcal/45 g chick/d. However, during this period the small intestines increased in weight and protein content by 80% or more. The decr...
متن کاملThermoregulation in Newly Hatched Black-legged Kittiwakes
The development of gull chicks is typically considered semi-precocial, because the birds remain in or near the nest for some days after hatching and depend on parental care, but hatch with downy coverings and possess some thermoregulatory ability (Drent 1967; Palokangas and Hissa 1971; Dawson et al. 1972, 1976; Dunn 1976; Dawson and Bennett 1980. 1981). Newlv hatched chicks of several gull spec...
متن کاملUnsupervised statistical learning in newly hatched chicks
The ability to extract probabilistic information from visual inputs has been reported in human adults and infants (reviewed in [1,2]), and in adults of non-human species, though only under supervised (conditioning) procedures [3]. Here, we report spontaneous sensitivity to the probabilistic structure underlying sequences of visual stimuli in newly hatched domestic chicks using filial imprinting...
متن کاملNewly hatched chicks solve the visual binding problem.
For an organism to perceive coherent and unified objects, its visual system must bind color and shape features into integrated color-shape representations in memory. However, the origins of this ability have not yet been established. To examine whether newborns can build an integrated representation of the first object they see, I raised newly hatched chicks (Gallus gallus) in controlled-rearin...
