Assortative mating in a fiddler crab

Behaviour, 2016
Non-random mating, particularly positive size-assortative mating, is common and can have major evolutionary consequences. The causes of size-assortative mating, however, are rarely examined. Here we explore the possibility of sexual selection, mate availability and mating constraints causing the strong correlation between male and female sizes in the ...

Synchronized courtship in fiddler crabs

Nature, 1998
The apparent paradox posed by the synchronization of mating displays by males competing to attract females has provoked considerable interest among evolutionary biologists1,3. Such synchronized sexual signalling has only been documented for communicationusing light flashes (bioluminescence) or sound.

Planktonic fiddler crab (Uca longisignalis) are susceptible to photo-induced toxicity following in ovo exposure in oiled mesocosms.

Environmental Science and Technology, 2020
Benthic organisms may be exposed to polycyclic aromatic hydrocarbons (PAHs) in marine sediments as the result of oil spills. PAH photo-induced toxicity, which has been documented in a wide range of early life stage (ELS) aquatic biota, is a phenomenon by

Neural asymmetry in male fiddler crabs

Brain Research, 1983
In adult male fiddler crabs, Uca pugnax, there is a marked enlargement of the 1st thoracic ganglion and its nerve root on the side of the major cheliped compared to the side of the minor cheliped. Retrograde uptake of cobalt via the cut ends of the motoneurons revealed a significant hypertrophy of their somata and dendritic fields on the major side of ...

Human influences on male waving behavior in the fiddler crab Leptuca pugilator

, 2020
Fiddler crabs are numerically dominant consumers within salt marshes and understanding how their behavior is influenced by human activities can therefore shed light on the health of disturbed marsh communities. We investigated how various levels of human

The Development of Asymmetry in the Fiddler Crab [PDF]

The American Naturalist, 1923
THE experiments of Przibram ('01, '07, '17) and of others have shown in certain species of decapod crustaceans, in which a larger and a smaller "claw" are normally present, that after the removal of the large claw the smaller claw develops into a large claw.
