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...
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 regulation of the spiny water flea (Bythotrephes longimanus) in a reservoir: Implications for invasion
Population regulation the spiny water flea a reservoir: Implications for invasion
2014/4/2
We conducted a 3-yr study of the population dynamics of the invasive cladoceranBythotrephes longimanusin Island Lake Reservoir (Minnesota) and compared our results to other human-constructed reservoir...
Rapid evolution of phenoloxidase expression, a component of innate immune function, in a natural population of Daphnia magna
Rapid evolution phenoloxidase expression innate immune function in a natural population Daphnia magna
2014/4/17
We show rapid microevolution of one component of invertebrate innate immunity, phenoloxidase activity, in a natural population of the water fleaDaphnia magna.InDaphniahatched out of different depths o...
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. ...

Population dynamics a freshwater calanoid copepod Complex responses changes in trophic status climate variability
2014/4/21
The long-term dynamics of the calanoid copepod Eudiaptomus gracilis were analyzed in Lake Constance, a deep lake that has been influenced strongly by changes in trophic status and climate variability ...
