However, for many animals, including butterflies, current research focuses primarily on estimating abundance and distribution without observing behavior. Because behaviors often respond to climate change before other metrics, understanding behavioral change is critical for future climate change research and projections. Therefore, we investigated weather related changes in adult butterfly behavior using snapshot behavioral observations taken as part of a four year study of butterfly abundance throughout North Dakota, USA. Across 1,107 site-visits, we categorized adult butterfly behavior using 146,610 observations while also recording local weather variables with each site visit. We found patterns in butterfly behavior within years, including more flying and less resting at sites that were warmer during that site visit. We also observed differences across years, including more flying overall and a weaker behavioral response to temperature in a year that was particularly cool and wet. Further incorporating such behavioral observations into abundance surveys can help lead to better insights about weather-related variation in behavioral patterns and their consequences for animals facing climate change.</p></div>","PeriodicalId":100260,"journal":{"name":"Climate Change Ecology","volume":"1 ","pages":"Article 100004"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ecochg.2021.100004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91680036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is still unclear why it was restricted to higher latitudes during the initial days and later cascaded in the tropics. Here, we analyzed 176 SARS-CoV-2 genomes across different climate zones and Köppen's climate that provided insights about within-species virus evolution and its relation to abiotic factors. Two genetically variant groups, named G1 and G2, were identified, well defined by four mutations. The G1 group (ancestor) is mainly restricted to warm and moist, temperate climate (Köppen's <em>C</em> climate) while its descendent G2 group surpasses the climatic restrictions of G1, initially cascading into neighboring cold climate <em>(D)</em> of higher latitudes and later into the hot climate of the tropics <em>(A)</em>. It appears that the gradation of temperate climate <em>(Cfa-Cfb)</em> to cold climate <em>(Dfa-Dfb)</em> drives the evolution of G1 into the G2 variant group, which later adapted to tropical climate <em>(A)</em> as well. It seems this virus followed an inverse latitudinal gradient in the beginning due to its preference towards temperate <em>(C)</em> and cold climate <em>(D)</em>. Our work elucidates virus evolutionary studies combined with climatic studies can provide crucial information about the pathogenesis and natural spreading pathways in such outbreaks, which is hard to achieve through individual studies. Mutational insights gained may help design an efficacious vaccine.</p></div>","PeriodicalId":100260,"journal":{"name":"Climate Change Ecology","volume":"1 ","pages":"Article 100005"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ecochg.2021.100005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91679931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As climate change ensues, animals may experience chronic stress due to persistent warmer temperatures and environmental conditions altered by weather extremes, such as wildfires and storms, which are expected to increase in frequency and intensity. This chronic stress has the potential to cause changes in animal responses to acute stress, but whether such changes occur is unclear. Here, we investigated whether new environmental conditions caused by wildfire affected the fight-or-flight component of the acute stress response of a widespread social insect. We compared thatch ant (<em>Formica obscuripes</em>) behavior in neighboring sagebrush steppe areas that were unburned or burned three months prior. As predicted, we found that ant workers primarily defended their colonies by attacking a threatening stimulus, but ants in the burned environment were more likely to flee from the stimulus. While causal mechanisms require further study, these findings suggest that ant workers provide less protection for their colonies following wildfire, which may increase individual worker survival but make colonies more vulnerable to antagonists. As chronic stress due to wildfires and other shifting climatic variables becomes more widespread, understanding changes in animal responses to acute stressors will be crucial for anticipating animal survival in the Anthropocene. We suggest several research priorities for work on stress-related animal behaviors in environments altered by climate change, including greater focus on invertebrates.</p></div>","PeriodicalId":100260,"journal":{"name":"Climate Change Ecology","volume":"1 ","pages":"Article 100012"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ecochg.2021.100012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90372861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
