Wandering in male fiddler crabs (Uca tangeri): alternative reproductive tactic or a functional constraint?
The ‘aggressive wandering’ behaviour of male fiddler crabs is well documented in several species and is usually described as an apparently random movement through a population, punctuated by threats and combat directed at displaying males, and superficial burrow explorations. It has been suggested that wandering males are mainly low condition individuals with a regenerating major claw, unsucces...
متن کاملSpectral sensitivity of four species of fiddler crabs (Uca pugnax, Uca pugilator, Uca vomeris and Uca tangeri) measured by in situ microspectrophotometry.
Fiddler crabs have compound eyes that are structurally fairly well understood. However, there has been much debate regarding their spectral sensitivity and capacity to enable colour discrimination. We examined the visual pigments of two North-American species (Uca pugnax and U. pugilator), one species from the Indo-West Pacific (U. vomeris) and the only Eastern-Atlantic species (U. tangeri) of ...
متن کاملRobotic crabs reveal that female fiddler crabs are sensitive to changes in male display rate
Males often produce dynamic, repetitive courtship displays that can be demanding to perform and might advertise male quality to females. A key feature of demanding displays is that they can change in intensity: escalating as a male increases his signalling effort, but de-escalating as a signaller becomes fatigued. Here, we investigated whether female fiddler crabs, Uca mjoebergi, are sensitive ...
متن کاملFiddler crabs
What are fiddler crabs? Fiddler crabs belong to the genus Uca. They are members of the ocypodid family of brachyuran crabs, the most recent marine animals to have invaded land. They spend the first part of their life as aquatic plankton and only settle in the intertidal zone after their last larval moult. Adults live in burrows on intertidal mudand sand-flats within dense, mixedage, mixed-sex a...
متن کاملEffects of temephos (Abate 4E) on fiddler crabs (Uca pugnax and Uca minax) on a Delaware salt marsh.
The nontarget effects of temephos (as Abate 4E, 44.6% active ingredient) on fiddler crabs were examined on the salt marsh at Bombay Hook National Wildlife Refuge, near Dover, DE. Six 170 x 170-m plots were established; 3 were sprayed on 4 occasions at a rate of 1.5 fl oz/acre (0.054 kg active ingredient/ha) and 3 were controls. On each plot, marsh fiddler crab (Uca pugnax) populations were moni...
