Heart Monitors On Wild Narwhals Reveal Alarming Responses To Stress（图）
Heart Monitors Wild Narwhals Alarming Responses Stress
2017/12/19
Narwhals released after entanglement in nets and outfitted with heart monitors performed a series of deep dives, swimming hard to escape, while their heart rates dropped to unexpectedly low levels of ...
Coral Tissue Thickness as a Bioindicator of Mine-Related Turbidity Stress on Coral Reefs at Lihir Island,Papua New Guinea
Coral Tissue Thickness Bioindicator Mine-Related Turbidity Stress Coral Reefs Lihir Island Papua New Guinea
2015/7/15
Work described here assessed the feasibility of using variations in tissue thickness in massive Porites corals as a bioindicator for mine-related sediment stress. We examined parameters influencing co...
Temperature-induced stress leads to bleaching in larger benthic foraminifera hosting endosymbiotic diatoms
Temperature-induced stress bleaching larger benthic foraminifera hosting endosymbiotic diatoms
2014/4/4
Physiological mechanisms of bleaching were studied on larger benthic foraminifera (LBF) hosting endosymbiotic diatoms. Amphistegina radiata, Heterostegina depressa, and Calcarina hispida were exposed ...
Role of oxidative stress in seasonal and daily vertical migration of three krill species in the Gulf of California
Role of oxidative stress seasonal
2014/4/17
Vertical distribution and abundance of three numerically dominant krill species (Nyctiphanes simplex,
Nematoscelis difficilis, and Euphausia eximia) were surveyed in the Gulf of California to underst...
Stoichiometric dietary constraints influence the response of copepods to ultraviolet radiation-induced oxidative stress
Stoichiometric dietary constraints the response of copepods ultraviolet radiation-induced oxidative stress
2014/4/17
We carried out field experiments in two clear mountain lakes of both hemispheres (Lake Los Ca′ ntaros,Patagonia, Argentina, and Lake La Caldera, Sierra Nevada, Spain) performing a full factorial desig...
Iron limitation across chlorophyll gradients in the southern Drake Passage: Phytoplankton responses to iron addition and photosynthetic indicators of iron stress
Iron limitation chlorophyll gradients in the southern Drake Passage Phytoplankton responses iron addition photosynthetic
2014/4/21
Processes influencing phytoplankton bloom development in the southern Drake Passage were studied using shipboard iron-enrichment incubations conducted across a surface chlorophyll gradient near the An...
Response of nonprotein thiols to copper stress and extracellular release of glutathione in the diatom Thalassiosira weissflogii
non protein thiols copper stress extracellular release glutathione diatom Thalassiosira weissflogii
2014/5/9
We studied the dynamic changes of cellular thiols and the extracellular release of glutathione (GSH) during growth of the marine diatom Thalassiosira weissflogii under varying levels of copper (Cu) ad...
Taxonomic variability of phosphorus stress in Sargasso Sea phytoplankton
Taxonomic variability phosphorus stressLSargasso Sea phytoplankton
2014/5/19
Low inorganic phosphorus (SRP) concentrations and high inorganic nitrogen to phosphorus ratios suggest that phytoplankton production in the northwestern Sargasso Sea may be controlled to some extent b...
Hydrodynamics of larval settlement: The influence of turbulent stress events at potential recruitment sites
Hydrodynamics larval settlement turbulent stress
2014/5/27
We describe a laboratory investigation into the effect of turbulent hydrodynamic stresses on clam larvae in the settlement phase of the recruitment process. A two-component laser-Doppler anemometer (L...
