The Limits to Growth Model: Still Prescient 50 years Later

In this 2022 report, Club of Rome member Gaya Herrington re-analyzes the "limits to growth" model from 1972 and finds that the conclusions have not fundamentally changed: we are on a precarious peak of production and consumption that leaves us with a binary choice for the future. If we want our youth and future generations to inherit a livable world, we will need to fundamentally change our production and consumption practices. As Herrington says: "But growth can no longer be humanity’s ultimate goal.

We are Hiring a Researcher!

What’s Wrong with (Most) Connectivity Modeling?

(The author has carried out and published most of the connectivity modeling described here, with some of the earliest (e.g., for CA) and largest (e.g., for China) connectivity models. Over the same period, he has also collected and published wildlife connectivity data/evidence, including using camera traps, wildlife-vehicle collision, opportunistic and transect observation, animal sign, GPS-collars, and genetic approaches. The opinions here are based on this experience.)

2023 Year-in-Review & 2024 What’s Next?

Bad News: It’s been a year of many firsts around the world. Most heat records were broken, including for the hottest year on record and highest ocean-surface temperatures. There were consequences of this heat for things we know how to measure (like wildfires, sea-ice cover and glacial melting) and many unknown consequences for myriad microbial, plant, and animal species and communities.

New Road Ecology Center Article: Large-Extent Evaluation of Linkage Models

"Linkage" models are usually developed based on human assumptions about wildlife response to disturbance, and assume perfect knowledge of landscapes by wildlife.  They also result in idealized "linkages" or similar emphasis areas for connectivity conservation.  They are rarely developed based on occurrence or movement information for multiple species, or validated using wildlife occurrence or movement data. In this paper we evaluated 4 connectivity models at the California extent (424,000 km2) and one at a quarter of that extent (Mojave desert).

Happy Easter/Ostara

Hi Road Ecology Center friends. What a wonderful Spring its turning out to be. This is a quick message to wish you a belated Ostara and an early Easter.
