Sperm limitation: possible impacts of large male-selective harvesting on reproduction of the coconut crab Birgus latro
For many biological resources, larger males are more likely to be harvested than smaller ones. In such harvested populations, the remaining males are relatively small and participate in more matings than in pristine populations. Because the number of sperm passed to females generally decreases with decreasing male body size and increasing male mating frequency, the reproductive success of femal...
متن کاملEffects of long-term frozen storage on the compositions of free amino acids and nucleotide-related compounds of the coconut crab Birgus latro
This study examined the effects of long-term frozen storage (-20 °C for 5 months) of free amino acids (FAAs) and nucleotide-related compounds (NRCs) in muscle and hepatopancreas of the coconut crab Birgus latro. Although long-term frozen storage had little effect on FAA composition in muscle, the amounts of several FAAs increased in the hepatopancreas that may be the result of protein decom...

متن کاملAdaptations to a Terrestrial Existence by the Robber Crab, Birgus Latro L. Iii. Nitrogenous Excretion
Nitrogenous excretion by the terrestrial anomuran crab Birgus latro L. was examined. The main excretory product was uric acid, representing 79-5 % of total excretory nitrogen. It was eliminated as white faeces separate from undigested food material and made up 82-6% of excretory faecal nitrogen. The faeces were the principal route of nitrogenous excretion, accounting for 96-2% of total excretio...
متن کاملAdaptations to a terrestrial existence in the robber crab Birgus latro L. IX. Hormonal control of post-renal urine reprocessing and salt balance in the branchial chamber.
The terrestrial robber crab Birgus latro L. regulates the composition of its final excretory product (termed P) depending on the availability of dietary salt by reabsorbing ions from urine passed over the gills. Laboratory and field-based studies investigated the nature of the mechanisms of control of this branchial ion uptake. B. latro were prepared such that their branchial chambers could be ...
