TI  - Tropical amphibians in shifting thermal landscapes under land-use and climate 
      change.

AB  - Land-cover and climate change are both expected to alter species distributions 
      and contribute to future biodiversity loss. However, the combined effects of 
      land-cover and climate change on assemblages, especially at the landscape scale, 
      remain understudied. Lowland tropical amphibians may be particularly susceptible 
      to changes in land cover and climate warming because many species have narrow 
      thermal safety margins resulting from air and body temperatures that are close to 
      their critical thermal maxima (CT(max) ). We examined how changing thermal 
      landscapes may alter the area of thermally suitable habitat (TSH) for tropical 
      amphibians. We measured microclimates in 6 land-cover types and CT(max) of 16 
      frog species in lowland northeastern Costa Rica. We used a biophysical model to 
      estimate core body temperatures of frogs exposed to habitat-specific 
      microclimates while accounting for evaporative cooling and behavior. Thermally 
      suitable habitat area was estimated as the portion of the landscape where species 
      CT(max) exceeded their habitat-specific maximum body temperatures. We projected 
      changes in TSH area 80 years into the future as a function of land-cover change 
      only, climate change only, and combinations of land-cover and climate-change 
      scenarios representing low and moderate rates of change. Projected decreases in 
      TSH area ranged from 16% under low emissions and reduced forest loss to 30% under 
      moderate emissions and business-as-usual land-cover change. Under a moderate 
      emissions scenario (A1B), climate change alone contributed to 1.7- to 4.5-fold 
      greater losses in TSH area than land-cover change only, suggesting that future 
      decreases in TSH from climate change may outpace structural habitat loss. 
      Forest-restricted species had lower mean CT(max) than species that occurred in 
      altered habitats, indicating that thermal tolerances will likely shape 
      assemblages in changing thermal landscapes. In the face of ongoing land-cover and 
      climate change, it will be critical to consider changing thermal landscapes in 
      strategies to conserve ectotherm species.
