Herbarium Records Reveal Earlier Bloom Times In Three Southern Appalachian Plant Species, Melanie Flood, Mark Davis, Ashlee Mccaskill

Georgia Journal of Science

Plant phenology, especially the onset of flowering in angiosperms, is a useful tool for studying the effects of climate change on native flora because it is influenced by temperatures. Numerous studies in different biomes have provided evidence of earlier bloom times in response to increasing temperatures. We examined herbarium specimen data to determine whether three spring-blooming species (Sanguinaria canadensis, Iris cristata, and Trillium rugelii) at the southern terminus of the Appalachians exhibit a similar change in onset of flowering over several decades. All three species exhibited significantly earlier flower onset during the past 120 years, a change that could have ...


Climate Sensitivity And Potential Vulnerability Of Guatemalan Fir (Abies Guatemalensis) Forests In Totonicapán, Guatemala, Talia G. Anderson, Daniel Griffin, Kevin Anchukaitis, Diego Pons, Matthew Taylor May 2018

Climate Sensitivity And Potential Vulnerability Of Guatemalan Fir (Abies Guatemalensis) Forests In Totonicapán, Guatemala, Talia G. Anderson, Daniel Griffin, Kevin Anchukaitis, Diego Pons, Matthew Taylor

Journal of Latin American Geography

Despite continued forest loss and extensive demand for wood products throughout Guatemala, the locally managed and protected forests of Totonicapán remain some of the most intact within the country. Here, we study the growth rings of Guatemalan fir (Pinaceae; Abies guatemalensis Rehder; pinabete) at Totonicapán to assess environmental influences on tree growth and the potential vulnerability of these forests to climate change in the western highlands. We find that late summer and dry season precipitation are critical drivers in annual ring-width variability and that tree growth responds negatively to warm sea surface temperature anomalies in the eastern tropical Pacific. Considering ...
