Capture data for American Robins (Turdus migratorius) at a fall migration banding station in Mid-Michigan from 2012 - 2019
<p>At the Burke Lake Banding Station in Bath, Michigan we captured American robins (Turdus migratorius) during fall migration from 2011 to 2019. The data shared consists of capture date and age. The data are used only for looking at the relative ratio of hatching year (HY) to after-hatching year (AHY) robins captured during fall migration. </p>
Data from: Global warming intensity of biofuel derived from switchgrass grown on marginal land in Michigan
<p>Energy crops for biofuel production, especially switchgrass (<em>Panicum virgatum</em>), are of interest from a climate change perspective. Here, we use outputs from a crop growth model and life cycle assessment (LCA) to examine the global warming intensity (GWI; g CO<sub>2</sub> MJ<sup>-1</sup>) and greenhouse gas (GHG) mitigation potential (Mg CO<sub>2</sub> year<sup>-1</sup>) of biofuel systems based on a spatially explicit analysis of switchgrass grown on marginal land (abandoned former cropland) in Michigan, USA. We find that marginal lands in Michigan can annually produce over 0.57 hm<sup>3</sup> of liquid biofuel derived from nitrogen-fertilized switchgrass, mitigating 1.2-1.5 Tg of CO<sub>2</sub> per year. About 96% of these biofuels can meet the Renewable Fuel Standard (60% reduction in lifecycle GHG emissions compared with conventional gasoline; GWI ≤ 37.2 g CO<sub>2</sub> MJ<sup>-1</sup>). Furthermore, 73-75% of these biofuels are carbon-negative (GWI less than zero) due to enhanced soil organic carbon (SOC) sequestration. However, simulations indicate that SOC levels would fail to increase and even decrease on the 11% of lands where SOC stocks >> 200 Mg C ha<sup>-1</sup>, leading to carbon intensities greater than gasoline. Results highlight the strong climate mitigation potential of switchgrass grown on marginal lands as well as the needs to avoid carbon rich soils such as histosols and wetlands and to ensure that productivity will be sufficient to provide net mitigation.</p>

Fig. 2.—Verified instances of wolves killing cattle (depredations) in Michigan, 1996–2013. The solid line indicates losses from throughout the geographic range of wolves in Michigan, excluding losses that occurred on 1 farm. The dashed line is the additional losses attributable to that 1 farm, where poor animal husbandry likely increased the risk of depredations (see "Characterizing the Problems"). The number of depredations declined considerably just prior to the planning and implementation of Michigan's 1st wolf hunt in 2013. Source: Michigan Department of Natural Resources (May 2014).

Fig. 1.—Timeline of key political events pertaining to the management of Michigan wolves. The details of each event are given in "Chronology of Political Events." Events above the timeline disfavor wolves and events below the timeline favor wolves. Dashed boxes indicate actions initiated by citizens. Solid boxes indicate actions initiated by the government. Key actors in the timeline are the Michigan Natural Resource Commission (NRC), Michigan Department of Natural Resources (DNR), and the United States Endangered Species Act (ESA). The online version of this figure includes color to indicate which events were associated with the executive branch (green), the courts (black), and each of the particular laws—Public Act (PA) 520 (blue), Senate Bill (SB) 288 and PA 21 (red), and PA 281 (magenta).
