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.
