Application of short fasting methods to induce molting
in commercial laying hens.
Because the main focus of our study was to investigate tag loss in relation to the molting
stage, only males were considered because they have a higher probability of molting
annually compared to sexually mature females (Comeau and Savoie, 2001).
The objective of this study was to investigate the impact of long-term exposure of pyrene on molting
and reproduction in the model estuarine invertebrate, the grass shrimp.
We studied a population of Wood Thrushes (Hylocichla mustelina) at the Hemlock Hill Biological Research Area in Crawford County, Pennsylvania, USA (41[degrees]46' N, 79[degrees]56' W), for two breeding seasons (25 Apr to 20 Sep 2007-2008), and used radio-telemetry to monitor off-territory movements and molting
Web and web decoration sizes prior, during, and after molting
events were analyzed with an ANOVA.
We also tested date of first capture and initial mass of molting
birds using two-sample t-tests.

The lobster will keep molting
and growing throughout its lifetime.
Multiple molt series are thought to be an adaptation for increased foraging efficiency in birds with time constraints for molting
(Tucker 1991, Hedenstrom and Sunada 1999, Pyle 2005, Rohwer et al.
2003), and are crucial to elevated growth and molting
success (Wen et al.
The mortality in the laboratory was low, most pronounced in the 4th and 5th instars and was associated mainly with molting
Second, the organism would have had to die and be fossilized during the minuscule fraction of its life span spent molting
