Response of Ocypode quadrata to storm waves on an urbanized sandy beach

Is Ocypode Quadrata (fabricius, 1787) a Useful Tool for Exposed Sandy Beaches Management in Bahia State (northeast Brazil)?

Influence of waves and horseshoe crab spawning on beach morphology and sediment grain-size characteristics on a sandy estuarine beach

The effects of wave action and horseshoe crab spawning on the topography and grain-size characteristics on the foreshore of an estuarine sand beach in Delaware Bay, New Jersey, USA were evaluated using data collected over six consecutive high tides. Data were gathered inside and outside a 25 m long exclosure constructed to create a control area free of disturbance by crabs. The density of crabs...

Monitoring human impacts on sandy shore ecosystems: a test of ghost crabs (Ocypode spp.) as biological indicators on an urban beach.

Sandy beaches comprise one of the most important coastal resources worldwide, providing habitats to threatened vertebrates, supporting underappreciated invertebrate biodiversity, and delivering crucial ecosystem services and economic benefits to mankind. Monitoring of the natural resource condition of sandy beaches and assessments of the ecological impacts of human disturbance are, however, rar...

Moderate Dehydration Decreases Locomotor Performance of the Ghost Crab, Ocypode quadrata

The effect of dehydration on the aerobic metabolism and endurance of sustained, terrestrial locomotion was determined for the ghost crab, Ocypode quadrata. The rate of evaporative water loss, measured as the percentage of decrease in body mass per hour, was influenced by ambient temperature (Ta). Increasing Ta from 240 C to 300 C (40%-50% relative humidity) increased the rate of water loss from...

Skeletal muscle fiber types in the ghost crab, Ocypode quadrata: implications for running performance.

Ghost crabs possess rapid running capabilities, which make them good candidates for comparing invertebrate exercise physiology with that of more extensively studied vertebrates. While a number of studies have examined various aspects of running physiology and biomechanics in terrestrial crabs, none to date have defined the basic skeletal muscle fiber types that power locomotion. In the current ...
