Avoidance, movement, and mortality: The interactions between a protistan grazer and Heterosigma akashiwo, a harmful algal bloom species
Avoidance movement mortality

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...

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
font style='font-size:12px;'>
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,...

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...

font style='font-size:12px;'>
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...

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...
Mortality estimates from age distributions: Critique of a method used to study seagrass dynamics
Mortality estimates age distributions Critique of a method used study seagrass dynamics

2014/5/26
Age structure of seagrass samples has been used to estimate survival and recruitment and then used to estimate population growth rate. Survival rate can be estimated from age structure only if the pop...
