Determination of selection gradients using multiple regression versus Structural Equation Modeling (SEM) Determination of selection gradients using multiple regression versus Structural Equation Modeling (SEM)
Selection studies involving multiple intercorrelated independent variables have employed multiple regression analysis as a means to estimate and partition natural and sexual selection's direct and indirect effects. These statistical models assume that independent variables are measured without error. Most would conclude that such is not the case in the field studies for which these...

Formation and regression of the corpus luteum of the American alligator Formation and regression of the corpus luteum of the American alligator
Luteal morphology of the American alligator is unique when compared to other reptiles but is similar to that of its phylogenetic relatives, the birds. The theca is extensively hypertrophied, but the granulosa never fills the cavity formed following the ovulation of the ovum. The formation of the corpus luteum (CL) is correlated with elevated plasma progesterone concentrations, which...

Can Dugongs Survive in Palau? Can Dugongs Survive in Palau?
In August 1991 we surveyed dugongs Dugong dugon in the coastal waters of Palau using methods similar to aerial surveys conducted in 1977, 1978 and 1983. Twenty-six dugongs (including four calves) were seen, a count within the range obtained previously. The rate at which dugongs were seen per unit flight-time was lower than for any of the other surveys, despite the observers being more...

Size-dependent, sex-dependent and seasonal changes in insulin-lige growth-factor-I in the loggerhead sea turtle Size-dependent, sex-dependent and seasonal changes in insulin-lige growth-factor-I in the loggerhead sea turtle
This study examines size-dependent, sex-dependent, and seasonal fluctuations in plasma insulin-like growth factor-I (IGF-I) concentrations in loggerhead sea turtles (Caretta caretta). Loggerhead turtles (n = 158) were captured in shrimp trawler nets during a 12-month survey in Cape Canaveral Channel, Florida. Plasma samples were analyzed using a validated heterologous radioimmunoassay...

Estimating shallow subsidence in microtidal salt marshes of the southeastern United States: Kaye and Barghoorn revisited Estimating shallow subsidence in microtidal salt marshes of the southeastern United States: Kaye and Barghoorn revisited
Simultaneous measurements of vertical accretion and change in surface elevation relative to a shallow (3-5 m) subsurface datum were made in selected coastal salt marshes of Louisiana, Florida, and North Carolina to quantitatively test Kaye and Barghoorn's contention that vertical accretion is not a good surrogate for surface elevation change because of autocompaction of the substrate...

Organochlorine residues in bat guano from nine Mexican caves, 1991 Organochlorine residues in bat guano from nine Mexican caves, 1991
Samples of bat guano, primarily from Mexican free-tailed bats (Tadarida brasiliensis), were collected at nine bat roosts in caves in northern and eastern Mexico and analysed for organochlorine residues. DDE, the most abundant residue found in each cave, was highest (0.99 p.p.m. dry weight) at Ojuela Cave, Durango. Other studies of DDE in bat guano indicate that this concentration is too...
