The Academy Awards have made history with breakthroughs for minorities in the past — but with this year's nominations, observers are noting how white the Oscars are, with no actors of color nominated in any of this year's acting categories.

It marks the least diverse nominations since 1998. People have been speaking out about this disconnect, with films like "Selma" being shut out of the acting nominations (though it did pick up a Best Picture nomination).

CELL SCIENCE AT A GLANCE

A National Science Foundation-funded study found that Charles Darwin's famous finches defy what has long been considered a key to evolutionary success: genetic diversity. The research on finches of the Galapagos Islands could change the way conservation biologists think about a species' potential for extinction in naturally fragmented populations. Researchers examined 212 tissue samples from museum specimens and living birds. Some of the museum specimens in the study were collected by Darwin himself in 1835. Only one of the extinct populations, a species called the vegetarian finch, had lower genetic diversity compared to modern survivors. Specifically, researchers believe a biological phenomenon called sink-source dynamics is at play in which larger populations of birds from other islands act as a "source" of immigrants to the island population that is naturally shrinking, the "sink." Without these immigrant individuals, the natural population on the island likely would continue to dwindle to local extinction. The immigrants have diverse genetics because they are coming from a variety of healthier islands, giving this struggling "sink" population inflated genetic diversity.

When conducting research involving the testing of human biospecimens, investigators and their institutions should routinely consider whether and how to return individual research results on a study-specific basis through an informed decision-making process, says a new report from the National Academies of Sciences, Engineering, and Medicine.

Current cancer control efforts in the United States typically are fragmented and uncoordinated, but taking a systems approach to establish a U.S. National Cancer Control Plan would address the challenge more holistically, says a new report from the National Academies of Sciences, Engineering, and Medicine.

U.S. colleges and universities should take a more intentional, inclusive, and evidence-based approach to mentoring students in STEMM (science, technology, engineering, mathematics, and medicine) – a shift that could engage and help retain a broader group of students in these fields, says a new report from the National Academies of Sciences, Engineering, and Medicine.

For decades, the Ford Foundation Fellowship programs have contributed to building a more equitable and diverse U.S. higher education system.

Increasing diversity among employees is a priority for many organizations, which spend substantial resources on diversity initiatives.

California State Senator Kevin de Leon says he’ll introduce legislation next month to get the state’s public employees retirement system off of coal.

Just back from ho-hum international talks in Lima, where he was a member of California's delegation, de Leon spoke at a conference in Oakland. It was sponsored by NextGen Climate, a nonpartisan group founded by billionaire philanthropist Tom Steyer to raise the profile of climate change among issues in the U.S. political debate.

“With coal power in retreat, and the value of coal dropping, it’s time for us to lead again in moving our massive state portfolios to lower carbon investments,” De Leon said. “Divestment is about matching your values with your investment strategy — and still seeing positive financial returns… California has prohibited its energy companies from buying or importing coal power, and state funds should match that.”

De Leon proposes to divest the nation’s two largest public pension funds from coal. The California Public Employees Retirement System, or CALPERS, is the nation’s largest, controlling about $295 billion as of the end of September.  The California School Teachers Retirement System is a sister fund for pensions of nearly 850,000 California teachers. CALSTRS controls another $187.1 billion dollars in potential investments.

Burning coal for energy is a major source of greenhouse gases that are warming the planet. The move would lend momentum to a divestment movement already underway, largely targeted at investment funds belonging to colleges and universities nationwide.

Stanford and Pitzer College in Claremont are among a dozen universities that have pulled investments out of the coal industry. But others, including the University of California have refused.

A new study has investigated the effects of set-aside management —when fields are taken out of agricultural production — on common invertebrate decomposers in soil. The diversity of woodlice species was higher in set-aside fields compared to neighbouring wheat fields and this effect increased in older set-asides. This study highlights the importance of set-aside areas as habitats for soil invertebrates, which are important for soil health.

KPCC recently reported on the tech world’s diversity problem. Technology firms face challenges in hiring diverse staffs of its coders, web developers and software engineers.

It’s also a challenge at nonprofits such as Southern California Public Radio,  parent of 89.3 KPCC, which has always sought to build a staff that reflects the region it serves. The section of that staff that develops the KPCC app and makes its website run is all white and mostly male.

But a small talent pool means the diversity challenge is even greater for nonprofits and even smaller tech firms.

“The first problem is that all of the people working for me are male,” says Alex Schaffert, the one female on KPCC’s tech team.  “I’m kind of focusing on maybe getting another girl into the mix.”

Schaffert can use the term “girl” because she happens to be the leader of the tech team:  KPCC’s Managing Director of Digital Strategy and Innovation. 

Why diversity is important

Schaffert recently launched the topic of diversity – or lack thereof – at a weekly meeting of her team. She expected a “stilted and awkward” discussion from the five white men on her team, but a few of them didn’t hold back.  

“Not having diversity represented on the team leaves us more susceptible to circular thinking and everyone sort of verifying each other's assumptions,” said Joel Withrow,  who was serving at the time as KPCC’s Product Manager. “It impacts the work. It limits what you’re able to build.”

Sean Dillingham, KPCC’s Design and Development Manager, said living in a diverse community is what attracted him to Los Angeles, and he wants diversity in his immediate work team, too.

“When I look at other tech companies, I will often go to their ‘about us’ page, where they’ll have a page of photos of everyone, and I am immediately turned off when I just see just a sea of white dudes, or even just a sea of dudes,” Dillingham said.

Big competition, small talent pool

Dillingham and Schaffert are currently recruiting heavily to fill two tech-savvy positions. When a reporter or editor job opens up at KPCC, Schaffert says close to 100 resumes come in.

"But if you post a programmer job, and you get three or four resumes, you may not get lucky among those resumes," she says. "There may not be a woman in there. There may not be a person of color in there."

In other words, the talent pool is already small, and the diversity challenge makes it even smaller. KPCC is competing for talent with Google and Yahoo and all the start-ups on L.A.’s Silicon Beach. 

Schaffert’s being proactive, mining LinkedIn and staging networking events to attract potential candidates. She’s also trying to make sure KPCC’s job descriptions don’t sound like some she's seen in the tech world.

"If you read between the lines, they’re really looking for someone who is male and is somewhere between 25-30 years old and likes foosball tables and free energy drinks in the refrigerator," Schaffert says. “So you read between lines, and you know that they’re not talking about me, a mother of two kids who also has a demanding career. They're talking about someone different.”

Pay vs. passion

Schaffert's challenges and approaches to dealing with them are similar to those of Mary Ann de Lares Norris, the Chief Operating Officer at Oblong Industries. Based in downtown Los Angeles and founded in 2006, the company designs operating platforms for businesses that allow teams to collaborate in real time on digital parts of a project.

“I think technology and diversity is tough,” Norris told KPCC.  She’s proud her company’s management ranks are diverse, but says only 12 percent of its engineers are female. “Pretty standard in the tech industry, but it’s not great,” Norris says. “We really strive to increase that number, and all of the other companies are also, and it's really hard.”

Like Schaffert at KPCC, Norris works hard fine-tuning job descriptions and communicating that her company values diversity and work-life balance. But sometimes, it just boils down to money.

"We have to put out offers that have competitive salaries,” Norris says, adding that she can’t compete with the major tech firms. "The Googles and the Facebooks of the world can always pay more than we can. So we attract people who are passionate about coming to work for Oblong.  And, of course, we also offer stock options."

KPCC doesn’t have the  stock options, but we’ve got plenty of passion. Could that be the secret recruiting weapon for both small tech companies and nonprofits?  

LinkedIn recently surveyed engineers about what they look for in an employer. Good pay and work-life balance were the two top draws. Slightly more women prioritized work-life balance and slightly more men chose the big bucks. 

Clinical Entrepreneurship professor Adlai Wertman says that, historically, nonprofits and small businesses actually had the upper hand over big companies in recruiting minorities and women.

"There’s a feeling that they’re safer, more caring environments, less killer environments, and we know that corporate America has been the bastion of white males," said Wertman. 

But Wertman says that advantage disappears in the tech world because of the "supply-and-demand" problem with talent. When big firms decide to focus on diversity – as some have recently — they have plenty of resources.

"They’re always going to be able to pay more, and in truth they’re getting access to students coming out of these schools in ways that we as nonprofits and small companies never will," said Wertman. 

Wertman worked 18 years as an investment banker on Wall Street, then left to head a nonprofit on L.A.’s skid row. Now he heads the Brittingham Social Enterprise Lab Enterprise Lab at USC’s Marshall School of Business. He believes that, early on, the big companies have the best shot attracting diverse tech talent. But in the long run, much of that talent will turn back to smaller firms and nonprofits.

"I think ultimately people vote with where they’re most comfortable, where 'my values align with my employer's values, and if I don’t feel those values align, then I’m going to leave,'" Wertman said. "Ultimately, I think, for a lot of women and minorities, there’s a lot of value alignment within communities that are doing good in the world."

Biodiversity on organic farms is, on average, 34% higher than on conventional farms, according to a recent study. The researchers used data from a large number of studies to show that this figure has remained stable over the last 30 years.

Converting grassland to arable land can reduce the diversity of nematodes, predatory mites, earthworms and enchytraeid worms in the soil, according to a study by Dutch researchers. However, they found that restoring arable land to grassland did not fully restore the diversity of these four groups during the course of the four-year study.

The widespread use of higher-yielding improved varieties of crops as part of the ‘Green Revolution’ has averted the conversion of between 18 to 27 million hectares of forests, woodlands and pastures in the period 1965 to 2004, according to a recent study. However, its authors caution that the relationship between these crops and land use change is complex, and good governance is needed to protect biodiversity from future expansion of agricultural land.

Policy measures to protect biodiversity must be scientifically sound in order to deal with the complexity of nature and the human pressures on nature. This thematic issue reports on research which can help policy makers understand biodiversity in water and different ways in which human activity can be managed to ensure both wildlife and humans benefit from healthy aquatic and marine ecosystems.

Diverse agricultural systems can sustainably improve food security and supply a varied, healthy diet for people, according to a recent analysis of the benefits of agricultural biodiversity. The food-based approach, when integrated with other strategies, can be used to tackle malnutrition, micronutrient deficiencies and the impact of climate change on farming.

The main factors affecting household food waste in the EU have been identified by an analysis of the 2013 Flash Eurobarometer survey (n.388). On an individual level, the main factors include age, gender, income and environmental attitudes. On the national level, the most significant factor is median disposable income. The authors suggest their results could help develop campaigns targeted at groups that generate the most household waste.

TEvery kilometre travelled by car incurs costs to the individual and society that are more than six times those of travelling by bicycle, a new study suggests. The researchers presented a cost-benefit analysis developed for Copenhagen, finding that cars resulted in costs of 0.50 €/km in comparison to 0.08 €/km for bikes.

Woodlands in the grounds of old manor houses or castles can provide high quality habitat for numerous forest species, a recent study from Estonia concludes. The researchers found that, compared to nearby forests, old rural park woodlands appeared to be better at supporting biodiversity.

To keep Europe’s ecosystems healthy, we need to protect biodiversity. How can the ecosystem service approach help? And how can we capture people’s more deeply held values beyond mere money?

Synthetic biology may propose solutions to some of the greatest environmental challenges, such as climate change and scarcity of clean water. However, the introduction of novel, synthetic organisms may also pose a high risk for natural ecosystems. Check out our infographics on some of the history and science behind synthetic biology.

A new EU-commissioned report has investigated the social value of biodiversity conservation, particularly in terms of its links to employment. It estimates that 35% of jobs in developing countries and 7% of jobs in the EU are dependent on ecosystem services.

Information about geodiversity — i.e. the variety of the material, non-biological parts of the natural world — could be better used and more integrated in environmental management in the UK, finds new research. The authors examined the inclusion of geodiversity information in UK assessments and identified a number of areas where geoscience knowledge is vital for informing ecosystem management.

Individuals and groups of individuals have been influential in changing the Tisza River water policy in Hungary, according to a new study. A shift away from engineering solutions towards sustainable flood management was achieved through new policy ideas being recognised by civil servants at the national level and a regional coalition championing the ideas at the local level.

Increases in population and urbanisation are challenging current systems of water supply. A new study has assessed existing examples of alternative supply systems, such as wastewater reclamation, rainfall collection and desalination of seawater. It suggests that adopting several types of system may provide a better and more flexible solution.

A new study has investigated the restoration of a damaged estuary in Spain by comparing the costs of installing sewage systems with the associated benefits for water quality and biodiversity in the area. Long-term benefits, particularly in the inner part of the estuary, increased with investment in sewage treatment schemes.

Measures to protect biodiversity can also improve carbon storage and water flow regulation, research indicates. In a Spanish protected area, researchers mapped biodiversity, carbon storage and water flow regulation, and found there was substantial overlap between the three.

Wetland biodiversity may fall under climate change, a new study suggests. The researchers' experiments indicated that, overall, plant growth in wetlands will be boosted, but a small number of plant species well suited to the warmer conditions will out compete other species. However, climate change's effects on biodiversity may be less severe if plants are able to move to cooler locations, towards the poles.

The world's most comprehensive digital biodiversity database has been developed, enabling access to over 177 million records. However, over two-thirds of the records are from just three countries: the USA, Sweden and the UK, and focus on certain groups such as birds. Changes in policy and funding could help widen the scope of the data.

A new global study on the economics of ecosystem services and biodiversity loss suggests that governments can achieve more resilient economies and receive higher rates of return on their public investment strategies when they recognise and target the value of ecosystem services.

Many species around the world are likely to become extinct as ecosystems and the diversity of life found in them are threatened by pressures, such as pollution, overexploitation, climate change, invasive species, fragmentation, degradation and loss of habitat. A recent report has examined the causes of biodiversity loss and the policies surrounding efforts to tackle this loss

New research in Estonia indicates that plant biodiversity in field boundaries varies with features, such as ditches, trees and nearby roads. It suggests that, in addition to common non-weedy plants, more consideration should be given to rare weeds by broadening of field boundaries and reducing the use of agrochemicals and fertilisers near these boundaries.

According to researchers, opportunities for carbon sequestration and benefits for biodiversity offered by forest rehabilitation schemes mean they should be given greater value as a tool for carbon offsetting. A new study demonstrates the value of forest rehabilitation for rainforest birds.

New research has updated a major report on the monetary value of biodiversity. The second EU-funded Cost of Policy Inaction (COPI II) report has expanded the existing valuation database to include more regions, more ecosystems and more information on the services they provide and their economic values. The new data could be used to calculate a more accurate figure for the global value of biodiversity and ecosystem services.
