Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

open access: yesGlobal Change Biology Communications, EarlyView.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

A methodological proposal for the recovery of palynomorphs from snow and ice samples

open access: yesActa Botânica Brasílica, 2018
The procedures for a set of techniques to recover grains of pollen 26 and spores from liquid samples are described. Liquefied samples of matrices, such as melting lakes, snow and ice, can provide a record of climatic and environmental events at different

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

open access: yesGeological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

Enhanced Tire–Snow Sinkage Modeling for Optimized Electric Vehicle Traction Control in Northern China Snow Conditions

open access: yesWorld Electric Vehicle Journal
The interaction between tires and snow layer is fundamental for vehicle safety on snowy roads. Due to the instantaneous high torque output characteristics of electric vehicles, they are more prone to slipping when driving in snow, which exacerbates the ...
