Adaptive Significance of Reproductive Cycles in the Fiddler Crab Uca pugilator: A Hypothesis
TLDR
The relation of the time of reproduction to tide cycles may be an adaptation to increase to a maximum the probability that the final stage of the planktonic larvae will be transported by tidal currents to substrates suitable for adults.Abstract:
Semimonthly peaks in courtship behavior of male crabs coincide with peaks in the temporal distribution of receptive females. Females mate once each month, 4 to 5 days before one of the semimonthly spring tides. The relation of the time of reproduction to tide cycles may be an adaptation to increase to a maximum the probability that the final stage of the planktonic larvae will be transported by tidal currents to substrates suitable for adults.read more

Behavioural mechanisms of food selection.
TL;DR: This uniquely broad synthesis captures the state of the art in the study of diet selection and prescribes new objectives in theoretical development and research.

Ecology and evolution of mating systems of fiddler crabs (genus uca)
John H. Christy,Michael Salmon +1 more
TL;DR: There exist two broad mating patterns in the fiddler crabs, which most western and Indo‐Pacific species mate on the surface of intertidal substrates near burrows females defend and males of many American species court from and defend burrows to which females come for mating.

Adaptive significance of the timing of larval release by crabs
Steven G. Morgan,John H. Christy +1 more
TL;DR: The hatching times of 46 species worldwide support the contention that predation, primarily on newly hatched larvae, and not other sources of mortality, selects for synchronous hatching by crabs.
Linking larval settlement to larval transport: assumptions, potentials, and pitfalls
TL;DR: In this paper, the authors discuss the potentials and pitfalls of using settlement rate time series in posing questions about larval transport, and discuss the processes that generate smooth and peaked settlement time series, and use of settlement time-series in identifying the temporal and spatial scales of physical transport.

Lunar Reproductive Cycles of Benthic-Brooding Reef Fishes: Reflections of Larval Biology or Adult Biology?
TL;DR: If hatchling biology is of general importance to paternal brooders, there must be considerably more interspecific variability in hatchling ecology than is generally assumed, and adult-biology hypotheses represent generally underemphasized alternatives that have at least as much explanatory potential as larval- biology hypotheses.

The role of pelagic larvae in recruitment to populations of adult decapod crustaceans in the York River estuary and adjacent lower Chesapeake Bay, Virginia☆
TL;DR: There appear to be two basic mechanisms of recruitment of young to estuarine decapod crustacean populations: recruitment by retention of larvae and recruitment by immigration of juveniles and adults.

Distribution and abundance of decapod crustacean larvae in the York River estuary and adjacent lower Cheaspeake Bay, Virginia, 1968–1969
TL;DR: In this article, surface and bottom plankton samples taken with a Clarke-Bumpus Quantitative Plankton Sampler at monthly intervals over a two-year period were examined for decapod crustacean larvae.
