Genetic diversity couldn't save Darwin's finches

Full Text:

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.

Set-aside fields increase the diversity of decomposers in soil in Hungarian agricultural landscapes

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.

Small firms and nonprofits like KPCC struggle with technology's diversity problem

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."

Lower diversity of soil organisms in new farmland

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.

High-yield crops have curbed agricultural land expansion, but care needed to avoid negative biodiversity effects

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.

Warming boosts plant growth, but reduces species diversity

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.

Promoting biodiversity through agricultural field boundaries

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.
