The ascidians of South Padre Island, Texas were surveyed in August
2004. Because the subtidal area is limited to soft sediments, the survey was restricted
to marina floats and pilings, harbor buoys, boat hulls and other artificial substrates
which...
The parthenogenetic marbled crayfish, Marmorkrebs, has no known wild population, but has been introduced into natural ecosystems in two continents. Interactions with native crayfish, particularly through fighting, could affect the ecological impact...
As a defense strategy, many crustaceans perform one of two well described stereotyped single fast tailflips (~6 ms in adult crayfish),
which are triggered by a neural circuit that includes medial giant interneurons (MG) and lateral giant...
Digging is a distinct form of locomotion that poses different mechanical problems than other locomotor modes that are commonly used by crustaceans, e.g., walking, swimming. I examined the mechanisms of digging by shovel nosed lobsters (Ibacus...
Marmorkrebs, or marbled crayfish, are recently discovered parthenogenetic crayfish. Its origins are unknown, but it has been introduced into natural ecosystems and could become a highly invasive pest species. Marmorkrebs have potential as a model...
When attacked, many decapod crustaceans perform
tailflips, which are triggered by a neural circuit that
includes lateral giant interneurons, medial giant interneurons, and fast flexor motor giant neurons (MoGs). Slipper lobsters (Scyllaridae) lack...
Lobsters and crayfish are two of many decapod crustaceans that use escape tailflips when under attack. The neural circuitry responsible for escape behavior has been well studied in crayfish. This circuitry includes lateral giant interneurons (LG),...
The parthenogenetic marbled crayfish Marmorkrebs was discovered in the pet trade in Europe in the 1990s. Since then, its
distribution through the pet trade has spread from Europe to other continents, including North America. North American...
