The largest bird in North America was nearly wiped out. Here's how it fought its way back.

Many Animals Can?t Adapt Fast Enough to Climate Change

https://www.wired.com/story/many-animals-arent-adapting-fast-enough-to-survive-climate-change/?bxid=5cec276c2ddf9c4e32e7d3dd&cndid=52131893&esrc=Wired_etl_load&source=EDT_WIR_NEWSLETTER_0_DAILY_ZZ&utm_brand=wired&utm_campaign=aud-dev&utm_mailing=WIR_Daily_072419&utm_medium=email&utm_source=nl&utm_term=WIR_Daily

Paper: Adaptive responses of animals to climate change are most likely insufficient

https://www.nature.com/articles/s41467-019-10924-4#Fig3





Trait changes in response to temperature. For each study in the phenotypic responses to climate with selection (PRCS) dataset, the changes in morphological traits are shown in grey and the changes in phenological traits are shown in black. Each study is identified by the publication identity, the trait and the species. Studies are sorted by trait category (black: phenological; grey: morphological), and within it by species, trait name and publication identity. Overall, phenological traits in both the PRCS dataset (black) and the PRC dataset (dark blue) were negatively affected by temperature. Morphological traits were not associated with temperature in the PRCS (grey) and showed a tendency to a negative association with temperature in the PRC dataset (cyan). In the PRC dataset there was significant variation among taxa in the effect of temperature on phenological (blue) traits, and a tendency to such variation for morphological traits (cyan). See Fig. 2 for legend details. The majority of the species pictures were taken from Pixabay (https://pixabay.com/images/). The exceptions are a picture of red-billed gull (credit: co-author J.A.M.) and four pictures taken from Macaulay library (https://www.macaulaylibrary.org/).

North American Grasslands & Birds Report

https://www.audubon.org/conservation/working-lands/grasslands-report?ms=digital-eng-email-ea-x-engagement_20190729_eng-email_grasslands-report&utm_source=ea&utm_medium=email&utm_campaign=engagement_20190729_eng-email&utm_content=grasslands-report


Audubon scientists identified future strongholds that are likely to persist through projected climate and land-use changes. Consensus Priorities include these areas (which primarily occur in the wetland-dotted mixed prairies of the northern Great Plains and the already-arid grasslands in the south), existing Grassland Priority Conservation Areas, and vulnerable priorities defined as areas with high probability of land-use conversion.
