Nutrients– I’m OK With That
But, fish pee as a key component in reef health. I’ll let the research lead where it
does. Still, fish pee…
Recent studies suggest
that coral reefs, however, are just as dependent on these fish for key
nutrients that help coral grow. When fish urinate, they release phosphorus into
the water. This phosphorus, along with nitrogen excreted as ammonium through
the gills of fish, is crucial to the survival and growth of coral reefs.
A new study appearing Aug. 16 in Nature Communications takes this a step further, finding that in
coral reefs where fishing occurs, nearly half of these key nutrients are absent
from the ecosystem.
The main reason? Fewer
large-bodied and predator fish to pee nutrients into the water, the study
found.
“Part of the reason
coral reefs work is because animals play a big role in moving nutrients
around,” said lead author Jacob Allgeier, a postdoctoral researcher at the
University of Washington’s School of Aquatic and Fishery Sciences.
Why Is This Still A Discussion?
Neonicotinoids are a major factor in bee colony extinction.
It seems like a good idea to do something about it.
New research has provided some of the strongest evidence yet
that pesticides can do serious, long-term damage to bee populations. And the
findings may help fuel the ongoing debate about whether certain insecticides
should be permitted for agricultural use at all.
The new study, published Tuesday in the journal Nature Communications, examines the
question of whether the use of a common (and highly controversial) class of
pesticides called neonicotinoids can be linked to wild bee declines in England.
The results suggest that this could be the case.
Endangered Species Protection – Or Lack of Same
Any suspicion that Republican budget cuts and foot dragging
impact the ability of the government to evaluation and implement provisions of the Endangered Species Act?
Endangered species are
waiting in long lines for the federal government to make a decision.
That’s the conclusion of a study in the journal Biological Conservation on wait times for listing a species under the
Endangered Species Act.
Emily Puckett is the
lead author of the study. She’s a postdoctoral associate with Fordham
University. She analyzed what happened with 1,338 species since 1974. She says
according to the law, it’s supposed to take about two years to get through the
process.
“The median time that
they’re waiting is 12.1 years and not that two years. Some species are being
listed very quickly, but other species have essentially waited the entire
length of the ESA, up to 38 years before they’re ever listed," she says.
Puckett says reptiles,
fish, and mammals had much shorter wait times than invertebrates and plants.
She says one reason might be that many people have an easier time feeling
affection for, say, an eagle, than a snail.
Saving Wildlife In Africa
Thoughtful discussion that questions the philosophy of making wildlife a state owned entity has opposed
to a resource to local communities. Also,
touches on the question of conservation colonialism.
Cottar views bad
policy as inherently damaging for wildlife as “African governments continue to
impose inherited variations of colonial-era game laws, which make wildlife a
state-owned asset.” He also observes that Kenya, “under pressure from animal
rights-oriented NGOs, has chosen to use this state monopoly of wildlife to
impose complete bans and moratoriums on all commoditization or consumptive use
of wildlife, applying the theory that the more ‘devalued’ the wildlife, the
less incentive local people have to kill it.”
In other words, if Kenya’s natural resources
are unavailable to landowners, they will simply let it be, an idea that
organizations like the International Union for Conservation of Nature view as
both illogical and impractical.
Kenya’s policies are especially damaging since
the presence of wildlife causes losses of up to 48 percent of productivity
revenues from agriculture and domestic livestock, mostly due to predation, crop
damage, disease transfer, and infrastructure damage (Norton-Griffiths 2007).
Should an old, deposed lion, for example, repeatedly prey on a Maasai
pastoralist’s cattle, the pastoralist is not legally allowed to take any action
in defense of his livelihood that would result in the death of the big cat.
Though this law looks good on paper for the
offending lion, what usually follows is a much worse fate than if that lion was
permitted to be dealt with legally. More often than not, that same herdsman
will simply poison an entire pride illegally instead.
Is California Burning?
Global warming might have something to do with decades of low precipitation in the Western US. Oh, and the five year drought in
California. And, let’s now forget the potential for a megadrought if we
don’t reduce carbon emissions.
Gov. Jerry Brown has declared a state of emergency in the fast-moving Blue Cut Fire that has exploded
to 15,000 acres and forced more than 82,000 people out of their homes since it
broke out Tuesday morning in the Cajon Pass, officials said.
"There is
imminent threat to public safety, rail traffic and structures in the Cajon
Pass, Lytle Creek, Wrightwood and surrounding areas," according to the
Inciweb page.
An estimated 34,500
homes and 82,640 people have been affected by the evacuation warnings.
San Bernardino County
Sheriff’s officials were asking residents to heed evacuation orders for their
safety.
About 700 fire
personnel from the county fire department, CalFire and the San Bernardino
National Forest are on scene. Water and fire retardant drops are being made
over the fire.
Six San Bernardino
County firefighters were entrapped by flames while battling the fire and two of
them suffered minor injuries.
An unknown number of
structures have been damaged and destroyed.
