Pattern, Process, and Prediction in Marine Invasion Ecology
Invasions frequently continue long after dispersal corridors have been well established. Six interrelated processes (changes in donor regions, new donor regions, changes in recipient region, invasion windows, stochastic inoculation events, and dispersal vector changes) are examined to explain this phenomenon. The combination of these processes makes it difficult to forge a list of species from ...
متن کاملProminent Human Health Impacts from Several Marine Microbes: History, Ecology, and Public Health Implications
This paper overviews several examples of important public health impacts by marine microbes and directs readers to the extensive literature germane to these maladies. These examples include three types of dinoflagellates (Gambierdiscus spp., Karenia brevis, and Alexandrium fundyense), BMAA-producing cyanobacteria, and infectious microbes. The dinoflagellates are responsible for ciguatera fish p...
متن کاملThe chemical defense ecology of marine unicellular plankton: constraints, mechanisms, and impacts.
The activities of unicellular microbes dominate the ecology of the marine environment, but the chemical signals that determine behavioral interactions are poorly known. In particular, chemical signals between microbial predators and prey contribute to food selection or avoidance and to defense, factors that probably affect trophic structure and such large-scale features as algal blooms. Using d...
متن کاملMarine Ecology Progress Series
The urgent need to reduce the intense pressure and destructive power that modern fishing practices apply to the world’s fisheries, and the oceans that support them, is now widely recognized (e.g. FAO 2002a, Hilborn et al. 2003). However, there is far less agreement over the exact levels to which fishing mortality must be reduced and over how to reduce the indirect effects of fishing (e.g. bycat...
متن کاملMarine Ecology Progress Semes
Nanoplankton and picoplankton abundance and community grazing on picoplankton were deterrnined in surnmer and autumn at several stations in a productive coastal environment (Georges Bank. NW Atlantic Ocean) and in an oligotrophic oceanic ecosystem (Sargasso Sea). Ranges of heterotrophic nanoplankton (HNAN) abundance were 1.2 to 3.6 X 103 ceils rnl-' on Georges Bank, and 2.2 to 6.8 X 10' ceiis m...
