Projected climate-based range change between 1990-2010 and 2080-2100 for Hawaiian forest birds. Values for the raster include: 1- current climate range projected to be loss by end-of-century; 2- persisting climate-based range for species between now and end-of-century; 3- areas gained in climate-based range for the species between now and end-of-century. Species projected ranges are clipped by currently available compatible vegetation habitat. Manuscript output: Figure 1

Hawaiian forest birds are imperiled, with fewer than half the original > 40 species remaining extant. Recent studies document ongoing rapid population decline and project complete climate-based range losses for the critically endangered Kaua’i endemics ‘akeke’e (Loxops caeruleirostris) and ‘akikiki (Oreomystis bairdi) by end-of-century due to projected warming. Climate change facilitates the upward expansion of avian malaria into native high elevation forests where disease was historically absent. While intensified conservation efforts attempt to safeguard these species and their habitats, the magnitude of potential loss and the urgency of this situation require all conservation options to be seriously considered....

In Hawaiʽi and elsewhere, research efforts have focused on two main approaches to determine the potential impacts of climate change on individual species: estimating species vulnerabilities and projecting responses of species to expected changes. We integrated these approaches by defining vulnerability as the inability of species to exhibit any of the responses necessary for persistence under climate change (i.e., tolerate projected changes, endure in microrefugia, or migrate to new climate-compatible areas, but excluding evolutionary adaptation). To operationalize this response-based definition of species vulnerability within a landscape-based analysis, we used current and future climate envelopes for each species...

Past analysis has shown that temperature-dependent avian malaria is likely to reduce overall available Hawaiian forest bird habitat with temperature increases. We used a comprehensive database of forest bird sightings (over 42,000 points), the most up to date regional climate projections and state-of-the-art ensemble species distribution models to project shifts in distribution of all Hawaiian forest bird species due to climate change. Our results show that all forest bird species are expected to suffer large range losses by end of this century with single island endemics at a greater risk than more widespread species. Because most species require structurally complex forest habitat that may take decades to develop,...

Hawaiʻi is considered a worldwide biodiversity hotspot, with nearly 90 percent of its native plants found nowhere else in the world. However, about half of these native plants are imperiled by threats including human development, non-native species, and climate change. Through this project, scientists modeled the relative vulnerability of over 1,000 native plant species to the effects of climate change. A panel of experts in Hawaiian plant species assisted with the development of the model and verified its results. From the model, researchers were able to develop a vulnerability score for each plant species and identify categories of species with high, medium, and low vulnerability to climate change. This information...
