THE RELATIONSHIP BETWEEN DIET AND LARVAL DEVELOPMENT OF PALAEMONETES ,
1. Larvae of Palaemonetes pugio Holthuis and Palaemonetes vulgaris (Say) reared in the laboratory showed differences in survival, frequency of molting and rate of development which may be associated with the amount of food available.2. Larvae were unable to survive if fed diets of either single species or combinations of species of several unicellular ...

Diamond‐backed terrapins are estuarine turtles threatened by bycatch mortality in crab pots. We found that a standard method for estimating terrapin survival has a low capacity to detect the true effect of bycatch reduction devices (BRDs) with 95% certainty.

Mechanisms That Generate Resource Pulses in a Fluctuating Wetland. [PDF]
Animals living in patchy environments may depend on resource pulses to meet the high energetic demands of breeding. We developed two primary a priori hypotheses to examine relationships between three categories of wading bird prey biomass and covariates ...

HORMONAL REGULATION OF THE DISTAL RETINAL PIGMENT OF PALAEMONETES
1. After removal of one eyestalk the distal pigment of the intact eye of Palaemonetes light-adapts more slowly and to a less extent for a given illumination; dark-adaptation is unaffected.2. The eyestalks are the chief sources of light-adapting hormone; lesser amounts are found in brain, connectives and ventral ganglia.3.

Accumulation and Effect of Chromium on Protein and Glycogen Levels of Palaemonetes pugio [PDF]
Total metal accumulation and the levels of total protein and glycogen were measured in Palaemonetes pugio after exposing the animals to 0.05, 0.1 and 0.2 ppm concentrations of chromium over 1, 7 and 15 days. Metal accumulation in tisuues was measured using atomic absorbtion spectrophotometric techniques and the levels of total protein and glycogen were
