The lake under the ice in Antarctica

There may not be many wild places left on Earth, but Antarctica certainly is one. Winters are extremely hostile to life – certainly to human life – with extremely cold temperatures and months without sunlight. Even summers are cold, and the weather is dangerously moody. The sheer size of this ice-covered continent is breathtaking. It is much larger than Europe 14,200,000 km2) and essentially unpopulated except for a few researchers in a couple of stations and some tourists who reach the Antarctic peninsula on cruise ships during the few weeks this is possible to cross the treacherous Drake passage between Patagonia and Antarctica each summer.

Current Biology: The Anthropocene Special Issue

CITATION:
Current Biology. 2019  Vol. 29, No. 19: R942–R1054.
ABSTRACT:
This special issue of Current Biology includes a collection of Features, Reviews, Primers, Essays and Quick guides on a wide range of topics surrounding various detrimental impacts of human activity on the biosphere.

For most biologists, inhabiting the Anthropocene also means working in it. There are very few topics in the life sciences that are not confronted with Continue reading

Urban Ecology

As we get started with our series on the urban Anthropocene, I’d like to approach the topic as a biologist, and think of cities as places filled with various kinds of life.

“Relative impacts of mitigation, temperature, and precipitation on 21st-century megadrought risk in the American Southwest”

CITATION:
Ault, T.R. et al. 2016. Science Advances, vol. 2, e1600873
ON-LINE AVAILABILITY:
ABSTRACT:
Megadroughts are comparable in severity to the worst droughts of the 20th century but are of much longer duration. A megadrought in the American Southwest would impose unprecedented stress on Continue reading

“How humans drive speciation as well as extinction”

CITATION:
Bull, J.W. and Maron, M. 2016. Proceedings of the Royal Society B 283: 20160600.
ON-LINE AVAILABILITY:
ABSTRACT:
A central topic for conservation science is evaluating how human activities influence global species diversity. Humanity exacerbates extinction rates. But by what mechanisms does humanity drive the emergence of new species? Continue reading

The real inconvenient truth?

This will not be a very scientific post, but it is also not a rant. I am trying to understand something: why is there so little large scale planning and discussion about the inevitable and grave consequences of climate change?

There is a surprising amount of Continue reading

“Beyond DNA: integrating inclusive inheritance into an extended theory of evolution”

CITATION:
E. Danchin et al. 2011. Nature Reviews Genetics, vol. 12, pp. 475-486.
ON-LINE AVAILABILITY:
ABSTRACT:
Many biologists are calling for an ‘extended evolutionary synthesis’ that would ‘modernize the modern synthesis’ of evolution. Biological information is typically considered as being transmitted across generations by the DNA sequence alone, but accumulating evidence indicates that Continue reading

“Early warning of climate tipping points”

CITATION:
Timothy M. Lenton. 2011. Nature Climate Change 1, pp. 201-209.
ON-LINE AVAILABILITY:
ABSTRACT:
A climate ‘tipping point’ occurs when a small change in forcing triggers a strongly nonlinear response in the internal dynamics of part of the climate system, qualitatively changing its future state. Human-induced climate change could Continue reading

“Species-specific responses of Late Quartenary megafauna to climate and humans”

CITATION:
E.D. Lorenzen, et al. 2011. Nature 479, pp. 359–364.
ON-LINE AVAILABILITY:
ABSTRACT:
Despite decades of research, the roles of climate and humans in driving the dramatic extinctions of large-bodied mammals during the Late Quaternary period remain contentious. Here we use ancient DNA, species distribution models and the human fossil record to Continue reading

How do memes change how we live?

In a previous post I started speculating about memes and their potential role in cultural evolution. I believe that coming to a better understanding of the way memes operate is an important part of coming to a full conception of habitability. As I argued previously, we can’t fully understand Continue reading

Reframing landscape fragmentation’s effects on ecosystem services

CITATION:
Mitchell, M. G. E. et al. 2015. Trends in Ecology and Evolution,  Vol. 30, No. 4, pp. 190-198.
ON-LINE AVAILABILITY:
ABSTRACT:
Landscape structure and fragmentation have important effects on ecosystem services, with a common assumption being that fragmentation Continue reading

“Fifteen forms of biodiversity trend in the Anthropocene”

CITATION:
Brian J. McGill, et al. 2015. Trends in Ecology & Evolution, Vol. 30, No. 2, pp. 104-113.
ON-LINE AVAILABILITY:
ABSTRACT:
Humans are transforming the biosphere in unprecedented ways, raising the important question of how these impacts are changing biodiversity. Here we argue that our understanding of biodiversity trends in the Anthropocene, and our ability to protect the natural world, is impeded by Continue reading
