With field, laboratory, and modeling approaches, we examined the interplay among habitat structure, intraguild predation (IGP), and parasitism in an ongoing species invasion. Native Gammarus duebeni celticus (Crustacea: Amphipoda) are often, but not always, replaced by the invader Gammarus pulex through differential IGP. The muscle‐wasting microsporidian parasite Pleistophora mulleri infects the native but not the invader. We found a highly variable prevalence of P. mulleri in uninvaded rivers… 

Habitat Use and Population Dynamics of Blue Crabs, Callinectes sapidus, in a High-Salinity Embayment

It is hypothesize that tidal activity rhythms and microhabitat selection contribute to the observed spatial patterns within the high-salinity embayment.

Environmental Drivers of the Spatial and Temporal Distribution of Spawning Blue Crabs Callinectes sapidus in the Western Gulf of Mexico

AbstractThe blue crab Callinectes sapidus is an economically important shellfish found in the Gulf of Mexico and elsewhere. Recent declines in abundance of this species have driven progressive

Spatial patterns in the ovigerous Callinectes sapidus spawning migration: results from a coupled behavioral-physical model

Ovigerous blue crabs Callinectes sapidus use ebb-tide transport (ETT), a vertical migra- tory behavior in which crabs ascend into the water column during ebb tides, to migrate from estuar- ine adult

Life Stage, Gender and Movement of Blue Crabs (Callinectis sapidus) in Lake Mattamuskeet and Connecting Canals

Monitoring life stages at canal control structures, assessed gender ratios with recreational crabbing, learned from crabbers, and studied movements of tagged crabs in a canal connecting Lake Mattamuskeet to the Pamlico sound to understand how crabs move in response to physical variables.

Environmental and endogenous control of selective tidal-stream transport behavior during blue crab Callinectes sapidus spawning migrations

This study examined vertical swimming behavior of migrating female blue crabs tethered in habitats they could encounter during migration and found differences in swimming frequency among sites are hypothesized to be responses to environmental cues, including flow regime.

Environmental and endogenous control of selective tidal-stream transport behavior during blue crab Callinectes sapidus spawning migrations

Selective tidal-stream transport (STST) is used by many estuarine organisms. Spawning blue crabs use a form of STST, ebb-tide transport (ETT), to migrate to high-salinity areas of the lower estuary

The missing link: tidal‐influenced activity a likely candidate to close the migration triangle in brown shrimp Crangon crangon (Crustacea, Decapoda)

Variations in swimming activity of different-sized Crangon crangon were monitored under constant laboratory conditions immediately after being caught in the German Wadden Sea and performance of ebb tide activity allowed the shrimps to reach the preferred deeper winter and spawning areas.

Reproduction in Female Stone Crabs (Genus Menippe) from Tampa Bay, Florida: Interannual, Seasonal, and Temperature-Related Variation

ABSTRACT Knowledge of short- and long-term reproductive patterns is basic for numerous types of biological, ecological, evolutionary, and fisheries studies. Using data from more than 22 y of

Coastal Countercurrents Increase Propagule Pressure of an Aquatic Invasive Species to an Area Where Previous Introductions Failed

The establishment of many non-indigenous species is primarily controlled by propagule pressure, local environmental conditions, and biological interactions. An introduction is doomed to fail if any



Responses of estuarine crab megalopae to pressure, salinity and light: Implications for flood-tide transport

The responses of field-caught megalopae of the blue crab Callinectes sapidus and the fiddler crab Uca spp.

Variation In Planktonic Availability And Settlement Of Blue-Crab Megalopae In The York River, Virginia

Blue crab, Callinectes sapidus, megalopae and juveniles were sampled in the plankton and on natural and artificial settlement substrates (collectors) at two sites in each of two areas of a lower Chesapeake Bay tributary to examine spatial variability in blue crab recruitment.

Ultilization of a seagrass meadow and tidal marsh creek by blue crabs Callinectes sapidus. I. Seasonal and annual variations in abundance with emphasis on post-settlement juveniles

Blue crabs Callinectes sapidus Rathbun were sampled in a lower Chesapeake Bay seagrass bed and adjacent tidal marsh creek from October 1982 through December 1986, using a drop net and suction sampler to provide more accurate estimates of juvenile blue crab abundance.


Based on experimentally determined temperature-salinity preferences reported in the literature for Callinectes larvae, metamorphosis may be delayed in cooler offshore waters, thus increasing chances of long-range transport.

Seasonal distribution of larvae of Callinectes sapidus (Crustacea: Decapoda) in the waters adjacent to Chesapeake Bay

Analysis of stratified plankton samples collected from May through September 1980 indicated reproductive activity for Callinectes sapidus throughout the summer with a peak in late July, suggesting a two phase recruitment.

Transport of blue crab larvae by surface currents off Delaware Bay, USA

Results of the current meter measurements provide firm evidence of sustained northward flow of surface water on the inner shelf off Delaware Bay during late summer when C. sapidus larvae are common in the plankton.

Circatidal activity rhythms in ovigerous blue crabs, Callinectessapidus: implications for ebb-tide transport during the spawning migration

An endogenous rhythm in vertical migration does underlie the ebb-tide transport behavior of ovigerous blue crabs with mature embryos during their spawning migration.
