Invasion of Coastal Marine Communities in North America: Apparent Patterns, Processes, and Biases
Overall, the emergent patterns reflect interactive effects of propagule supply, invasion resistance, and sampling bias, and the relative contribution of each component re...
Global Invasions of Marine and Estuarine Habitats by Non-Indigenous Species: Mechanisms, Extent, and Consequences'
It is clear that non-indigenous species are a significant force of change in marine and especially estuarine communities globally and studies of marine communities that do not include NIS are increasingly incomplete.
Allometric constraints and variables of reproductive effort in brachyuran crabs

The number of eggs per brood was significantly better than brood weight as a predictor of the number of broods produced per year by a species, indicating that demographic pressure on fecundity rather than energetic considerations is the primary selective mechanism influencing annual reproductive effort.
Non‐indigenous species as stressors in estuarine and marine communities: Assessing invasion impacts and interactions
Invasions by non‐indigenous species (NIS) are recognized as important stressors of many communities throughout the world. Here, we evaluated available data on the role of NIS in marine and estuarine…
BIOTIC RESISTANCE TO INVASION: NATIVE PREDATOR LIMITS ABUNDANCE AND DISTRIBUTION OF AN INTRODUCED CRAB
The hypothesis that the native predator Callinectes sapidus provides biotic resistance to invasion and prevents the southward spread and establishment of Carcinus maenas is supported.
Guild structure and foraging impact of blue crabs and epibenthic fish in a subestuary of Chesapeake Bay
These experiments indicate that the Guild of epibenthic predators foraging activity not only has strong direct effects on infaunal community structure, but that the guild also has significant indirect effects oninfaunalcommunity organization and patch dynamics which are highly variable in space and time.
Population dynamics and habitat partitioning by size, sex, and molt stage of blue crabs Callinectes sapidus in a subestuary of central Chesapeake Bay
These data provide one of the best documented cases of habitat partitioning by size, sex and molt stage in crustaceans.
Evidence for sperm limitation in the blue crab, Callinectes sapidus
Seminal receptacle weight declined markedly for 2 mo following mating as seminal fluid disappeared to leave only spermatophores for long-term storage, which suggests that seminal fluid serves as a short-term sperm plug.
DENSITY‐DEPENDENT PREDATION, HABITAT VARIATION, AND THE PERSISTENCE OF MARINE BIVALVE PREY
A conceptual model detailing the relative importance of behavior, morphology, habitat features, and the basic components of predator–prey interactions to the survival of bivalve molluscs is developed and intended to be used as a heuristic tool to develop testable hypotheses.

Introduced populations can cause ecological and economic damage and are difficult to eradicate once they have established. It is therefore important to be able to predict both where species may…
