Wildfires driven more by lowered precipitation than elevated temperatures or reduced snowpack

Posted 06 Sep 2018 / 0

Proceedings of the National Academy of Sciences “Decreasing fire season precipitation increased recent western US forest wildfire activity” There’s a little bit of a “choose your climate change poison” to this study, but it is interesting to be able to isolate the specific climate-driven effects that are causing more wildfires to crop up.

Are corals riding ocean currents to exert climate change dominance over macroalgae?

Posted 06 Sep 2018 / 0

Proceedings of the National Academy of Sciences “Ocean currents and herbivory drive macroalgae-to-coral community shift under climate warming” What’s really interesting in this study is the interaction it discovered: climate change may change competitive dynamics, but it does so in the presence of other factors which also must be modeled in order to predict future competive Read More

Meta-analysis suggests that pesticides impair bee memory and learning

Posted 06 Sep 2018 / 0

I read about this first in Frontiers in Ecology and the Environment, but here is the actual article: Journal of Applied Ecology “Quantifying the impact of pesticides on learning and memory in bees” This is an important study, because it suggests that we need to ask more subtle questions about the impacts of pesticides on our pollinators!

No-till has some big no-catastrophic-climate-change potential

Posted 06 Sep 2018 / 0

I learned about this from reading Frontiers in Ecology and the Environment, but here are some other sources reporting on the same study… NPR St. Louis Public Radio “Missouri could offset carbon emissions from agriculture by conserving the soil, report says” Climate Central “Missouri Farms Hold Big Potential as Carbon Storehouse” These are exciting findings! They Read More

What might we discover in the ocean twilight zone?

Posted 30 Aug 2018 / 0

Science “What lives in the ocean’s twilight zone? New technologies might finally tell us” We tend to think that there’s nothing unexplored on the earth, that we know what kinds of organisms inhabit different ecosystems. So it’s pretty striking that there’s a whole area of the ocean that we know so little about. The scientific challenges Read More

Model suggests that warming climate will catalyze greater insect-pest crop losses

Posted 30 Aug 2018 / 0

Science “Insect threats to food security” Science “Increase in crop losses to insect pests in a warming climate” This is scary, especially since this is a global estimate that has never before been modeled. I found it interesting that the temperate-zone effects are most profound because the effects of warming are not so extreme as to lower Read More

Escape is a big risk in aquaculture

Posted 30 Aug 2018 / 0

Science “Chile’s salmon escape demands action” Feral crops and livestock can present potential invasive species problems on land, but it is easy to see how aquaculture would present even larger problems: although aquaculture does involve “domesticated fish”, those fish are far less dependent on human care than their terrestrial counterparts.

Is it possible that Trump’s science-adviser is a stealth climate-change accepter?

Posted 30 Aug 2018 / 0

Nature “Trump’s science-adviser pick hedges on climate change” There’s not a lot of reason to think that anyone can soften President Trump’s irresponsible stance on climate change action, but maybe Kelvin Droegemeier is trying to sneak some climate realism into the White House? It’s bizarre how these things work, but I am actually somewhat more optimistic Read More

Both primates have their own uses for the same land

Posted 30 Aug 2018 / 0

PNAS “Small room for compromise between oil palm cultivation and primate conservation in Africa” This study reaches what is probably not a surprising conclusion: if we want to grow tropical plants for food, we are likely to displace tropical mammals. Palm oil is particularly frightening because it seems to like to grow in areas where endangered Read More

Professor Jensen’s Guide to Urban Cycling

Posted 22 Aug 2018 / 0

Welcome to Brooklyn: it’s a great place to cycle if you know how to do so safely. In August of 2018 I was asked to give a one-hour workshop on urban cycling as part of Pratt’s new student orientation program. I figured that I should condense my thoughts on the why, how, when, where, and Read More
