Sapphirinid copepods as predators of doliolids: Their role in doliolid mortality and sinking flux
predators of doliolids Sapphirinid copepods

Unprecedented slow growth and mortality of the rare colonial cyanobacterium, Nostoc zetterstedtii, in oligotrophic lakes
Unprecedented slow growth rare colonial cyanobacterium
2014/4/4
Centimeter-large colonies of Nostoc zetterstedtii from a Swedish oligotrophic lake had the lowest growth and
mortality rates of any studied temperate macrophyte. Annual growth rates at two shallow si...
Avoidance, movement, and mortality: The interactions between a protistan grazer and Heterosigma akashiwo, a harmful algal bloom species
Avoidance movement mortality
2014/4/4
A reduction in predator-induced grazing pressure may be a mechanism that facilitates the formation and
persistence of harmful algal blooms. Here, the hypothesis was tested that the heterotrophic cili...
Seasonal dynamics ofPosidonia oceanicain Magalluf Bay (Mallorca, Spain): Temperature effects on seagrass mortality
Seasonal dynamics oceanicain Magalluf Bay Temperature effects seagrass mortality
2014/4/17
We recorded seasonal and interannual population dynamics of the endemic Mediterranean seagrass Posidonia oceanica in a shallow meadow, Magalluf Bay, Spain (39u30.259N, 2u32.599E), performing direct mo...
Sulfide exposure accelerates hypoxia-driven mortality
Sulfide exposure accelerates hypoxia-driven mortality
2014/4/17
The effect of the presence of sulfide on the survival of benthic organisms under hypoxia was tested using a meta-analysis of published experimental results evaluating the effects of the presence of hy...
Death by dissolution: Sediment saturation state as a mortality factor for juvenile bivalves
Sediment saturation state juvenile bivalves
2014/4/18
We show that death by dissolution is an important size-dependent mortality factor for juvenile bivalves.
Utilizing a new experimental design, we were able to replicate saturation states in sediments ...
Sex-related differential mortality of a marine copepod exposed to a toxic dinoflagellate
Sex-related differential mortality marine copepod exposed toxic dinoflagellate
2014/4/21
In this study we hypothesized that the sexes of the copepod Acartia hudsonica experience different mortalities when exposed to the toxic dinoflagellate Alexandrium fundyense. In laboratory experiments...
Sex-related differential mortality of a marine copepod exposed to a toxicdinoflagellate
Sex-related differential mortality marine copepod exposed toxicdin of lagellate
2014/4/18
In this study we hypothesized that the sexes of the copepod Acartia hudsonicaexperience different mortalities when exposed to the toxic dinoflagellate Alexandrium fundyense. In laboratory experiments,...
Viruses as mortality agents of picophytoplankton in the deep chlorophyll maximum layer during IRONAGES III
Viruses mortality agents picophytoplankton in the deep chlorophyll maximum layer IRONAGES III
2014/4/21
We report viral-induced mortality rates of the picoeukaryotic (two size classes) and prokaryotic (cyanobacteria Prochlorococcus and Synechococcus) phytoplankton during a cruise in the oligotrophic sub...
Bleaching, energetics, and coral mortality risk: Effects of temperature, light, and sediment regime
Bleaching energetics coral mortality risk Effects of temperature light sediment regime
2014/4/23
The most severe outcome of coral bleaching is colony mortality. However, the risk of mortality is one of the least understood consequences for reef corals under climate-change scenarios. Specifically,...
Dissolution mortality of juvenile bivalves in coastal marine deposits
Dissolution mortality juvenile bivalves coastal marine deposits
2014/5/14
We evaluate experimentally the effect of carbonate saturation state at the sediment-water interface (SWI) on survivorship of various size classes of the juvenile bivalve Mercenaria mercenaria. Populat...
Estimation of intergenerational drift dispersal distances and mortality risk for aquatic macroinvertebrates
intergenerational drift dispersal distances mortality risk aquatic macroinvertebrates
2014/5/22
Estimates of the total lifetime dispersal capacity of individuals comprising invertebrate drift in streams and rivers have proved very difficult to determine empirically. Here we use recent data on di...
Lysogeny and virus-induced mortality of bacterioplankton in surface, deep, and anoxic marine waters
bacterioplankton surface deep
2014/5/21
Lysogeny (bacteria containing inducible prophages) and lytic viral infection (bacteria in a lytic stage of infection)
were investigated at the community level in contrasting marine environments such ...
Stage-specific mortality of Calanus spp. under different predation regimes
Stage-specific mortality Calanus spp. different predation regimes
2014/5/27
We have applied the population surface method to estimate the mortality rates of eggs, nauplii, and copepodids of Calanus spp. in two Norwegian fjords with contrasting predator guilds. Efforts were co...
Impacts of nutrients and grazing mortality on the abundance of Aureococcus anophagefferens during a New York brown tide bloom
nutrients and grazing mortality abundance of Aureococcus anophagefferens a New York brown tide bloom
2014/5/26
Although nutrients and grazing both contribute to the formation of harmful algal blooms, research on these events has rarely considered both factors simultaneously. To ascertain the impact of nutrient...
