There are a number of ways that climate change is beginning to impact wildlife. Temperature increases and changes in precipitation can directly affect species, depending on their physiology and tolerance of environmental changes. Climate change can also alter a species' food supply or its reproductive timing, which indirectly affecting its fitness. Understanding these interactions is an important step in developing management strategies to help species survive the changing climate.
We integrated experimental and natural gradient field methods to investigate effects of climate change and variability on flowering phenology of 11 subalpine meadow shrub, forb, and graminoid species in Gunnison County, Colorado (USA). At a subalpine meadow site, overhead electric radiant heaters advanced snowmelt date by 16 d and warmed and dried soil during the growing season. At three additional sites, a snow removal manipulation advanced snowmelt date by 7 d without altering growing season soil microclimate. We compared phenological responses to experimental climate change with responses to natural microclimate variability across spatial gradients at small and landscape scales, as well as across a temporal gradient...
Climate change in Hawaiʻi is expected to result in increasing temperatures and varying precipitation through the twenty-first century. Already, high elevation areas have experienced rapidly increasing temperatures and there has been an increase in the frequency of drought across the Islands. These climatic changes could have significant impacts on Hawaiʻi’s plants and animals. Changes in temperature and moisture may make current habitat no longer suitable for some species, and could allow invasive species to spread into new areas. Hawaiʻi Volcanoes National Park is home to 23 species of endangered vascular plants and 15 species of endangered trees. Understanding how climate change may impact the park’s plants...
