Ecosystem Based Management: Managing for Everything or Nothing At All

by Bluegrass Blue Crab in Southern Fried Science



www.californiafires.com
Managing for stability just doesn’t work.
This epiphany has helped forge the development of ecosystem based management (EBM), theoretically a more holistic approach to natural resource management that is more in tune with natural processes.  However, we still haven’t worked out the kinks so something good in theory often falls flat.  A couple of recent [...]...

Mitochondria-free animals live in oxygen-starved basin

by Katie Kline in EcoTone

Researchers have discovered three species of Loricifera living in an oxygen-starved basin at the bottom of the Mediterranean Sea. Loricifera are marine sediment-dwelling animals consisting of a head, mouth, digestive system and outer shell called a lorica.

Sleeping sickness—a new cure for a neglected disease?

by geekheartsscience in geek!

Scientists validate a new drug target, the Trypanosoma brucei enzyme N-myristoyltransferase, in the fight against sleeping sickness, and have already identified and tested an inhibitor against this enzyme that successfully cures T. brucei infection in mice.
The study, published in the journal Nature, provides a much-needed boost to research into neglected tropical diseases, which are often associated with [...]... Read more »

Giant Birds And Terrified Monkeys

by Jason Goldman in The Thoughtful Animal

The Harpy Eagle (Harpia harpyja) is a nasty scary-looking muppethugging monster of a carnivorous bird. Female harpies weigh 14-20 pounds, and males weigh 8.5-12 pounds. They stand between 2.9 and 3.5 feet tall. The wingspan of the harpy eagle can reach 6 feet, 7 inches. The talons – sharp claws to grasp onto [...]... Read more »

Impulsivity and Addiction

by Dirk Hanson in Addiction Inbox


The perils of a hypersensitive dopamine system.

The brooding, antisocial loner, the one with impulse control problems, a penchant for risk-taking, and a cigarette dangling from his lip, is a recognizable archetype in popular culture. From Marlon Brando to Bruce Lee, these flawed heroes are perhaps the ones with restless brain chemicals; the ones who never felt good and never knew why (“What are you rebelling against?” “What’ve you got?”).

A recent study at Vanderbilt University, pu........ Read more »

Building Robots to Infiltrate Societies

by Cheshire in Cheshire


A bunch of scientists build robots which blend in with a society by learning their languages and customs. The intention of these robots is to subvert the societies by changing the how the locals think and act.
Sounds like something from a bad sci-fi movie, right? A Tea Party speech, perhaps?

Growth Needs Context

by Cole Bitting in Fable

What is Context? How Do We Use It?

What Happens When We Lose It?

One of our most essential life skills is the ability to build context - the core assumptions which enable effective choice of behavior. The literatures on posttraumatic growth, many forms of therapy, recovery from depression or significant loss describe new context as a foundational achievement: recovery happens as we create better, more valid assumptions about ourselves and the world around us.

Two other foundational qualities ........ Read more »

RSVP—A Cultural Construct?

by Krystal D'Costa in Anthropology in Practice

I saw this Op-Ed piece earlier this month about the decline of the RSVP, and it resonated strongly. It reminded me of my own experience last year when I organized my sister-in-law's (husband's sister) bridal shower. Apparently, I came very close to alienating the guest list, which contained mostly family members, because of the way my invitation was delivered.
The gathering was limited to "

When it doesn't matter where you're from

by TwoYaks in Gene Flow

People move animals around. It's what we do. Why are there Elk on Afognak island? Some guy thought it was a good idea at the time. Wildlife managers in the past were some of the biggest conduits for moving animals around, frequently en mass, back before biology really caught up with the profession. We can cite plenty of examples where moving animals around to do population rescues was a bad thing... Read more »

Closing the Window of Fear

by Shaheen Lakhan in Brain Blogger

Excessive fear is the cause of many psychopathologies. Although pharmacological interventions can help in preventing the retrieval of fear memories, they are toxic and involve a lot of side-effects. Till now, non-pharmacological interventions were only effective in suppressing the memory of fear for a short period. A new technique developed by scientists at the Center for [...]... Read more »

Explosive radiation (in) rocks!

by Alistair Dove in Deep Type Flow



Much like internal waves, I always loved the idea of explosive radiation.  Not the nasty, pernicious Chernobyl kind; I mean the rapid evolution of a whole bunch of species from a common ancestor, over a relatively short period of time.   There's a few textbook examples of explosive radiations, but none so well-worn (possibly even hackneyed) as that of the cichlid fishes in the rift lakes of ...

Fossil Fragments are Table Scraps of an Enormous Alligator

by Brian Switek in Dinosaur Tracking

I love B-grade monster movies, and one of my all time favorites is the 1980 creature feature Alligator. As its title suggests, the film’s protagonist is a 40-foot-long alligator, literally pumped up on steroids from consuming the bodies of medical research lab animals which had been dumped in the sewers under Chicago, and it spends [...]...

Geochronology of the Cryogenian glaciations

by Lab Lemming in Lounge of the Lab Lemming

A few weeks back Chris posted a lovely writeup of his work on the Oman cryogenian diamictites, and the snowball earth hypothesis. A recent paper on some Chinese diamictite ages has a nice summary of the chronology of this time period, so I thought I would throw it up here.First, a short introduction. Between about 750 and 580 million years ago, a number of glacial sediments appear in the ... Read more »

Speculation Surrounding Sporulation in the Mycobacteria

by Tim Sampson in The Times Microbial

by TimThe Mycobacteria are quite the unique genus; not quite Gram-positive due to their waxy mycolic acids on their outer surface, but certainly not Gram-negative as they do not have an outer lipid bilayer. (Although, there are some interesting micrographs showing a structural feature that does look a lot like a typical Gram-negative outer membrane on the surface of Mycobacteria.) Much slower growing than the average bacteria studied in the lab and not so easily manipulated genetically (though s........ Read more »

People have an intuitive understanding of the science of persuasion

by BPS Research Digest in BPS Research Digest

Psychologists have devoted entire careers to finding out how people can be persuaded but far less time investigating what people know intuitively about persuasion.Now Karen Douglas and colleagues at Kent University have bucked this trend with a paper which they say shows people have an intuitive understanding of how a person's thinking style affects their vulnerability to persuasion, known formally as 'the elaboration likelihood model'. This is the idea, supported by research findings, that peop........ Read more »

The Top Down Effect of Turbidity Within Marine Ecosystems

by Daniel Bassett in Chew the Fat

Most studies on turbidity investigate freshwater ecosystems and few studies have focused on the impacts of turbidity on marine ecosystems. Eianne et al. (1999) showed that invertebrate planktivores (jellyfish) replaced planktivorous fish within Norwegian turbid fiords. This was likely to be because increased turbidity levels reduced the possibility of foraging in visually oriented fish, while tactile feeding in jellyfish allowed them to continue to feed under light-limited conditions....
