Population Connectivity in Marine Systems:An Overview
Population Connectivity Marine Systems
2015/7/22
There is growing consensus that life within the world's ocean is under considerable and increasing stress from human activities (Hutchings, 2000; Jackson et al., 2001). This unprecedented strain on bo...
Larval Transport and Dispersal in the Coastal Ocean and Consequences for Population Connectivity
Larval Transport Dispersal Coastal Ocean Consequences Population Connectivity
2015/7/22
Many marine species have small, pelagic early life stages. For those species, knowledge of population connectivity requires understanding the origin and trajectories of dispersing eggs and larvae amon...
Observing Larval Transport Processes Affecting Population Connectivity:Progress and Challenges
Observing Larval Transport Processes Population Connectivity Progress and Challenges
2015/7/22
Population connectivity is inherently bio-physical: it is determined by physical transport and dispersion, as well as biological processes such as timing of spawning, larval behavior, and mortality. K...
Coupled Biological and Physical Models:Present Capabilities and Necessary Developments for Future Studies of Population Connectivity
Coupled Biological Physical Models Present Capabilities Necessary Developments Future Studies Population Connectivity
2015/7/22
The combination of wide-ranging spatial and temporal scales associated with the oceanic environment, together with processes intrinsic to the biology of marine organisms, makes the quantitative study ...
Understanding the connectivity of marine populations is vital for conservation and fisheries management, particularly for the strategic design of reserve systems. A recent proliferation of molecular a...
Population Connectivity and Larval Dispersal Using Geochemical Signatures in Calcified Structures
Population Connectivity Larval Dispersal Geochemical Signatures Calcified Structures
2015/7/22
The importance of larval dispersal to the population dynamics and biogeography of marine organisms has been recognized for almost a century (Hjort, 1914; Thorson, 1950). More recently, theoretical stu...
Population Connectivity and Conservation of Marine Biodiversity
Population Connectivity Conservation Marine Biodiversity
2015/7/22
An understanding of the extent to which marine populations are connected by larval dispersal is vital, both to comprehend past impacts and future prospects for sustaining biodiversity. Marine populati...
Population Connectivity and Spatial Management of Marine Fisheries
Population Connectivity Spatial Management Marine Fisheries
2015/7/22
Understanding dispersal pathways and population connectivity is an essential prerequisite for devising effective fishery management strategies in at least two critical ways. The first concerns the del...
Seamounts:Deep-Ocean Laboratories of Faunal Connectivity,Evolution,and Endemism
Seamounts Deep-Ocean Laboratories Faunal Connectivity Evolution Endemism
2015/7/7
Seamount systems that are geographically, hydrographically, topographically, and/or genetically "isolated" are likely to have developed highly endemic taxa and ecosystems. Although current estimates o...
Diel and lunar cycles of vertical migration extending to below 1000 m in the ocean and the vertical connectivity of depth-tiered populations
Diel and lunar cycles vertical migration extending below 1000 m the ocean the vertical connectivity depth-tiered populations
2014/4/2
We measured diel migration with 11 acoustic Doppler current meter profilers and consistently found diel and lunar cycles of vertical migration from 250 m down to the bathypelagic (> 1000 m). These mea...
Physical and biological controls on larval dispersal and connectivity in a highly energetic shelf sea

2014/4/2
Connectivity within marine species plays a fundamental role in population dynamics, genetic diversity, spread of disease, and resilience to human exploitation. However, for shellfish species that are ...
Population connectivity of the Olympia oyster in Southern California
Population connectivity the Olympia oyster Southern California
2014/4/16
The Olympia oyster is a useful model to study the population connectivity of estuarine invertebrates because it incorporates chemical information about the natal site into its shell before dispersal. ...
Using spatial statistics to infer scales of demographic connectivity between populations of the blue mussel, Mytilus spp.

2014/4/18
We conducted a large-scale survey of blue mussel (Mytilus spp.) populations and recruitment along 100 km of
the Southern shore of the St. Lawrence Estuary, Que′bec, Canada. By taking advantage of the...
