Data for: Temperature and intraspecific variation affect host-parasite interactions
<p>Parasites play key roles in regulating aquatic ecosystems, yet the impact of climate warming on their ecology and disease transmission remains poorly understood. Isolating the effect of warming is challenging as transmission involves multiple interacting species and potential intraspecific variation in temperature responses of one or more of these species. Here, we leverage a wide-ranging mosquito species and its facultative parasite as a model system to investigate the impact of temperature on host-parasite interactions and disease transmission. We conducted a common garden experiment measuring parasite growth and infection rates at seven temperatures using 12 field-collected parasite populations and a single mosquito population. We find that both free-living growth rates and infection rates varied with temperature, which were highest at 18-24.5°C and 13°C, respectively. Further, we find intraspecific variation in peak performance temperature reflecting patterns of local thermal adaptation—parasite populations from warmer source environments typically had higher thermal optima for free-living growth rates. For infection rates, we found a significant interaction between parasite population and nonlinear effects of temperature. These findings underscore the need to consider both host and parasite thermal responses, as well as intraspecific variation in thermal responses, when predicting the impacts of climate change on disease in aquatic ecosystems.</p>

Mineral soil moisture and temperature data from unburned stands used in the effects of variations in post-fire organic layer thickness studies in the Delta Junction region, 1995-2003
This database contains measurements of mineral soil temperature and moisture collected in unburned stands as part of an analysis of variations in the depths of surface organic layers found in burned and unburned black spruce stands, and the effects of variations in depth of burning on soil temperature and moisture, and organic layer carbon stocks. Data for the overall study were collected between 1995 and 2003 by Eric Kasischke (University of Maryland), Kathy O'Neill (Duke University), and Jill Johnstone (University of Alaska Fairbanks). Sites were located in burned black spruce stands within the perimeters of three recent fires (1987, 1994, and 1999), unburned black spruce stands adjacent to the burned stands, and within one black spruce stand that burned in 1956. The three fires were: (a) the 1987 Granite Creek fire located 15 km to the east of Delta Junction, Alaska USA, bordering the Alaska Highway on the North and Jarvis Creek on the south; the 1994 Hajdukovich Creek fire located 45 km southeast of Delta Junction Alaska, USA, bordering the Alaska Highway to the North and the Gerstle River to the West, and the 1999 Donnelly Flats fire, located 8 km south of Delta Junction, bordering Jarvis Creek to the east and the Richardson Highway on the west. Data that were collected and are in databases associated with this project include:; (1) organic layer depths in burned stands; (2) organic layer depths in unburned stands; (3) basal diameters of overstory trees in unburned stands and distance measures that can be used to estimate stand density; (4) mineral soil temperature and moisture data in burned stands; (5) mineral soil temperature and moisture data in unburned stands; and (6) bulk density and percent carbon data from different organic layers in unburned stands.

Data from: Spatial variation of the rain-snow temperature threshold across the Northern Hemisphere
We present the first continuous map of rain-snow air temperature thresholds over the Northern Hemisphere land surface, underlining the spatial variability of precipitation phase partitioning. Land surface models typically discriminate between rain and snow using a simple, spatially uniform air temperature threshold, but observations indicate the threshold is not static. Our analysis of a 29-year observational dataset (n = 17.8 million) shows the threshold varies significantly, averaging 1.0°C and ranging from -0.4°C to 2.4°C for 95% of Northern Hemisphere stations, with continental climates exhibiting the warmest thresholds and maritime the coolest. Relative humidity exerts the strongest control on phase partitioning, while surface pressure plays a secondary role. Simulations indicate the selection of a rain-snow threshold introduces significant uncertainty to snowfall frequency and that including relative humidity as a predictor variable provides the greatest improvement to precipitation phase prediction between 0.6°C and 3.4°C, the interval where phase partitioning is most uncertain.

Body mass, temperature, and pathogen intensity differentially affect critical thermal maxima and their population-level variation in a solitary bee
<p>Climate change presents a major threat to species distribution and persistence. Understanding what abiotic or biotic factors influence the thermal tolerances of natural populations is critical to assessing their vulnerability under rapidly changing thermal regimes. This study evaluates how body mass, local climate, and pathogen intensity influence heat tolerance and its population-level variation (SD) among individuals of the solitary bee <em>Xenoglossa pruinosa</em>. We assess the sex-specific relationships between these factors and heat tolerance given the differences in size between sexes and the ground-nesting behavior of the females. We collected <em>X. pruinosa</em> individuals from fourteen sites across Pennsylvania, USA that varied in mean temperature, precipitation, and soil texture. We measured the critical thermal maxima (CT<sub>max</sub>) of <em>X. pruinosa</em> individuals as our proxy for heat tolerance, and used quantitative PCR to determine relative intensities of three parasite groups—trypanosomes, <em>Spiroplasma apis</em> (mollicute bacteria), and <em>Vairimorpha apis</em> (microsporidian). While there was no difference in CT<sub>max</sub> between the sexes, we found that CT<sub>max</sub> increased significantly with body mass, and that this relationship was stronger for males than for females. Air temperature, precipitation, and soil texture did not predict mean CT<sub>max</sub> for either sex. However, population-level variation in CT<sub>max</sub> was strongly and negatively correlated with air temperature, which suggests that temperature is acting as an environmental filter. Of the parasites screened, only trypanosome intensity correlated with heat tolerance. Specifically, trypanosome intensity negatively correlated with the CT<sub>max</sub> of female <em>X. pruinosa</em> but not males. Our results highlight the importance of considering size, sex, and infection status when evaluating thermal tolerance traits. Importantly, this study reveals the need to evaluate trends in the variation of heat tolerance within and between populations, and consider implications of reduced variation in heat tolerance for the persistence of ectotherms in future climate conditions. </p>
Spatial variation in avian bill size is associated with temperature extremes in a major radiation of Australian passerines
<p>Morphology is integral to body temperature regulation. Recent advances in understanding of thermal physiology suggest a role of the avian bill in thermoregulation. To explore the adaptive significance of bill size for thermoregulation we characterized relationships between bill size and climate extremes. Most previous studies have focussed on climate means, ignoring extremes, and do not reflect thermoregulatory costs experienced over shorter time scales. Using 79 species (9,847 museum specimens), we explore how bill size variation is associated with temperature extremes in a large and diverse radiation of Australasian birds, Meliphagides. Overall, across the continent, bill size variation was associated with both climate extremes and means and was most strongly associated with winter temperatures; associations at the level of climate zones differed from continent-wide associations, were complex and non-linear, yet consistent with physiology and a thermoregulatory role for avian bills. We provide strong evidence that climate extremes have contributed to the evolution of bill morphology in relation to thermoregulation and demonstrate the importance of including extremes to understand fine-scale trait variation across space. Increasing frequency and intensity of climate extremes, a signature of climate change, may lead to changes in bill size, but this is yet to be tested.</p>
