Experiments with robots explain synchronized courtship in fiddler crabs [PDF]
SummaryMale fiddler crabs (Uca mjoebergi) produce highly synchronized courtship waves. Is this a cooperative behaviour because females preferentially approach groups that wave synchronously? Or is it a competitive behaviour because of female choice for males that wave first, with the resultant selection on males generating synchrony as an epiphenomenon

Abstract Pulses of resource availability along environmental gradients can filter the local and regional distribution of macrophyte and microbial mat communities in wetlands. Wetlands that experience short hydroperiods (i.e., <6 months with standing water) may cause macrophyte and microbial mat competition for water.

The Atlantic sand fiddler crab Uca pugilator, is an extremely abundant crab found along the eastern coast of the United States. Fiddler crabs have a life cycle with an obligatory planktonic larval phase of 30–90 days, which might be expected to lead to ...

Widespread crab burrows enhance greenhouse gas emissions from coastal blue carbon ecosystems
Fiddler crabs, as coastal ecosystem engineers, play a crucial role in enhancing biodiversity and accelerating the flow of material and energy. Here we show how widespread crab burrows modify the carbon sequestration capacity of different habitats across ...

A preference for a sexual signal keeps females safe. [PDF]
Predation is generally thought to constrain sexual selection by female choice and limit the evolution of conspicuous sexual signals. Under high predation risk, females usually become less choosy, because they reduce their exposure to their predators by ...

The behavioral responses of the fiddler crab, UCA PUGILATOR, to ionizing irradiation [PDF]
Thesis (M.A.)--Boston University. Note: Page 24 is missing.Many animals, invertebrates as well as vertebrates, have demonstrated an ability to somehow sense ionizing irradiation.

Object approach computation by a giant neuron and its relation with the speed of escape in the crab Neohelice [PDF]
Upon detection of an approaching object, the crab Neohelice granulata continuously regulates the direction and speed of escape according to ongoing visual information.

Burrow surveillance in fiddler crabs I. Description of behaviour [PDF]
SUMMARYWhen defending resources, animals need to reliably detect and identify potential competitors. Animals that live at high population densities would be expected to be efficient in this aspect of resource defence since the time lost in false alarms could be substantial and the failure of identifying a competitor could be very costly.

Links Between Child Executive Function and Adjustment: A Three‐Site Study
ABSTRACT Cross‐site comparisons indicate that East Asian children typically excel on tests of executive function (EF), but interpreting this contrast is made difficult by both the heavy reliance on testing in school settings and by the scarcity of studies that assess across‐site measurement invariance.

Simulations in the laboratory were used to investigate whether survivorship rates of Ucides cordatus youngsters produced in the laboratory are significantly affected by other crab species after their release in natural environments.
