Contrasting Population Structure from Nuclear Intron Sequences and mtDNA of Humpback Whales
Nuclear Intron Sequences mtDNA
2015/12/17
Powerful analyses of population structure require information from multiple genetic loci. To help develop a
molecular toolbox for obtaining this information, we have designed universal oligonucleoti...
Sardines,Anchovies and Other Fast-Growing Fish Species Vulnerable to Dramatic Population Plunges
Sardines Anchovies Other Fast-Growing Fish Species Vulnerable Dramatic Population Plunges
2015/8/13
A Rutgers marine biologist studying the rise and fall of fish populations worldwide recently made a counterintuitive discovery: ocean species that grow quickly and reproduce frequently, such as sardin...
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 ...

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

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...
Climate-Associated Regime Shifts Drive Decadal-Scale Variability in Recovery of North Atlantic Right Whale Population
Climate-Associated Decadal-Scale Variability North Atlantic Right Whale Population
2015/7/20
Despite an elevated mortality rate from lethal interactions with humans, the North Atlantic right whale population has continued to grow during the first decade of the new millennium. This unexpected ...
