Study of Belize Barrier Reef Shows Nitrogen Enrichment from Land-based Sources Doubled in Four Decades：What’s killing coral reefs in Florida is also killing them in Belize
coral reef nitrogen concentration algal blooms ecological system
2021/8/5
Only 17 percent of live coral cover remains on fore-reefs in Belize. A study finds new evidence that nitrogen enrichment from land-based sources like agriculture run-off and sewage, are significantly ...

Environmental Enrichment Turkish Saanen Growth Bipedal Animal Welfare
2016/7/27
As is in all economic activities, the highest yield per unit area is the main goal in animal production, while addressing the temperamental needs of animals often is ignored. Animal welfare is not onl...
There is overwhelming evidence that riverine
nutrients drive both the production of
phytoplankton and the size of the hypoxic

Challenges and opportunities for science in reducing nutrient over-enrichment of coastal ecosystems
reducing nutrient over-enrichment coastal ecosystems
2016/5/18
Nutrient over-enrichment has resulted in major changes in the coastal ecosystems of developed nations
in Europe, North America, Asia, and Oceania, mostly taking place over the narrow period of 1960 t...

Some of the largest scientific manipulation experiments conducted on our planet have enriched broad swaths of the surface ocean with iron. Surface ocean signatures of these iron enrichment experiments...
Metal enrichment of the intergalactic medium at z=3 by galactic winds
galactic winds intergalactic medium
2014/12/26
Studies of quasar absorption lines reveal that the low-density intergalactic medium (IGM) at z ~ 3 is enriched to between 10-3 and 10-2 solar metallicity. This enrichment may have occurred in an early...
Metal enrichment of the intergalactic medium in cosmological simulations
intergalactic medium formation starburst
2014/12/26
Observations have established that the diffuse intergalactic medium (IGM) at z ~ 3 is enriched to ~10-2.5 solar metallicity and that the hot gas in large clusters of galaxies (ICM) is enriched to - Z ...
Enrichment of the intergalactic medium by radiation pressure-driven dust efflux
intergalactic medium abundances
2014/12/26
The presence of metals in hot cluster gas and in Lyα absorbers, as well as the mass-metallicity relation of observed galaxies, suggest that galaxies lose a significant fraction of their metals to the ...
This paper discusses a semi-numerical method of investigating
the enrichment of the intergalactic medium by galactic winds. We
find that most galaxies at z ～ > 3 should be driving winds, and that (i...
Missing-iron problem and Type Ia supernova enrichment of hot gas in galactic spheroids
hot gas galactic spheroids
2014/12/22
Type Ia supernovae (Ia SNe) provide a rich source of iron for hot gas in galactic stellar spheroids. However, the expected supersolar iron abundance of the hot gas is not observed. Instead, X-ray obse...
