- Abstract/Description
-
The grass shrimp, Palaemonetes paludosus, was studied during a two year period from a population in southern Florida. The shrimp exhibited significant deviations from an expected sex ratio of 1:1 in certain size classes. Males were found more frequently in small to intermediate size classes while females dominated the largest size classes. Recruitment was continuous and ovigerous females were found year-round. Clutch size increased with increasing carapace length of the shrimp. A differential...

The shrimp exhibited significant deviations from an expected sex ratio of 1:1 in certain size classes. Males were found more frequently in small to intermediate size classes while females dominated the largest size classes. Recruitment was continuous and ovigerous females were found year-round. Clutch size increased with increasing carapace length of the shrimp. A differential growth rate may account for the variations in sex ratio among different size classes found in this shrimp.

- The effect of medroxyprogesterone (Depo-Provera) on the ovaries of captive cockatiels (Nymphicus holiandicus) during the reproductive cycle.
- Creator
- Juillerat, Dana Kale, Florida Atlantic University, Mahoney, Sheila A., Charles E. Schmidt College of Science, Department of Biological Sciences
- Abstract/Description
-
Depo-Provera, a drug manufactured by the Upjohn Company, has been used clinically to prevent egg-laying in several species of domestic birds. Two different doses of the drug plus a placebo injection of saline were administered to 54 cockatiels. All subjects appeared normal and healthy throughout the study except for two birds in the higher dose treatment which died of unknown causes. Control was studied through the direct observation of the ovary by means of laparoscopy, as well as monitoring...
Show moreDepo-Provera, a drug manufactured by the Upjohn Company, has been used clinically to prevent egg-laying in several species of domestic birds. Two different doses of the drug plus a placebo injection of saline were administered to 54 cockatiels. All subjects appeared normal and healthy throughout the study except for two birds in the higher dose treatment which died of unknown causes. Control was studied through the direct observation of the ovary by means of laparoscopy, as well as monitoring egg laying activity throughout the study. Depo-Provera at both doses tested appears to effectively decrease egg-laying activity in the captive cockatiel. All birds receiving the higher dose of Depo-Provera gained significant weight. Although the use of Depo-Provera may serve as a means of preventive medicine, there are serious side effects that should be considered.

- Larval release by the fiddler crab Uca thayeri: Timing and cues used under different tidal regimes.
- Creator
- Kellmeyer, Kay, Florida Atlantic University, Salmon, Michael, Charles E. Schmidt College of Science, Department of Biological Sciences
- Abstract/Description
-
Hatching rhythms of intertidal crabs vary in timing with species, burrow position, tidal regimes and larval vulnerability. Most fiddler crabs time larval release with the nocturnal high fide. This is possible in semidiurnal tidal regimes because there are nocturnal high tides each lunar day. However, mixed tidal regimes have a semidiurnal and a diurnal period. During the diurnal phase high fide occurs in the afternoon. This variation in tidal inundation patterns may influence the timing of...
Show moreHatching rhythms of intertidal crabs vary in timing with species, burrow position, tidal regimes and larval vulnerability. Most fiddler crabs time larval release with the nocturnal high fide. This is possible in semidiurnal tidal regimes because there are nocturnal high tides each lunar day. However, mixed tidal regimes have a semidiurnal and a diurnal period. During the diurnal phase high fide occurs in the afternoon. This variation in tidal inundation patterns may influence the timing of larval release. Comparisons between two populations of fiddler crab (Uca thayeri ), exposed to different tidal regimes, indicated they time larval release differently. The population exposed to semidiurnal tides timed larval release with the nocturnal high tide prior to the maximum amplitude tide. The population exposed to mixed tides timed larval release with the diurnal maximum amplitude tide. The differences between the populations can be related to their ecology but other variables may contribute.
