Weather data collected from Public Work's weather stations located around the Province.

Animals are expected to adjust their behavioural patterns to improve fitness outcomes, such as fecundity or offspring survival. For long-lived hibernators, decisions made in each annual cycle may reflect considerations not just for concurrent survival and reproduction, but also the pressure to maximize overwinter survival and future reproductive success. We examined how these elements manifest themselves in the body mass variation patterns of North American northern latitude temperate bats, whose size and roosting habits present considerable monitoring challenges. We characterized and compared the summer and fall mass variation patterns of little brown myotis (Myotis lucifugus) and northern myotis (M. septentrionalis) from a historic dataset. In summer, the estimated date of parturition was strongly associated with spring foraging conditions (low wind, low precipitation, warm temperatures), and mass gain associated with female reproduction conferred considerable differentiation between the mass variation patterns of females and males. In fall, differences were most apparent among species, although adults exhibited a greater capacity for rapid mass gain than juveniles. These results demonstrate how reproductive constraints and interannual survival have important influences on the behaviour of temperate bats. Future work should seek to quantify the fitness benefits of patterns identified in this study, such as the rate of prehibernation mass gain. Methods These data include bat capture records spanning capture surveys between 2000 and 2019 and weather data provided by Environment and Climate Change Canada. The capture data used in this project are the body mass values of bats captured by independent research teams in the Canadian provinces of New Brunswick, Nova Scotia, Prince Edward Island, Ontario, and the island of Newfoundland. In these projects, bats were captured with mist nets (Avinet, Dryden, New York, USA) and harp traps (Austbat Research Equipment, Lower Plenty, Victoria, Australia) by different research groups and assessed for standard morphometric and diagnostic criteria, including sex, age class (adult or juvenile per Kunz and Anthony 1982), and mass (g) to two decimal places. Upon initial screening of the dataset, we chose to proceed with little brown myotis and northern myotis because they were the two species with sufficient data for an informative comparison. The capture dates were recorded as Julian Date (1-365), and individual observations were grouped for analysis according to year, province, age-class (adult/juvenile), sex, and species. We categorized the initial full historical dataset according to capture record timing, location, individual sex, and individual age. We further screened records for suitability in our time series analysis, and the data presented here include those sets that met our critieria for summer and fall analysis: at least nine unique sampling nights and no sampling gaps longer than 20 days. We have included both the raw mass values and the LOESS nonparametric fitted values (span = 0.75, quadratic fit). We fitted the mass value records to the widest possible range available for the summer and fall groups, which were Julian Dates 158-207 (approximately June 7 - July 26) for summer and 227-262 (approximately August 15 - September 19) for fall. We chose not to fit exclusively between these dates because doing so would lose accuracy provided by captures outside that range for groups with more sampling. The environmental data here are raw hourly weather conditions at Canadian federal weather stations near bat capture sites. We considered temperature, wind, and precipitation when creating our foraging condition index, and weighed the data from a particular station according to the proportion of bats caught near it.

Data from a study of a servere cold event in February 2023 on the survival of hemlock woolly adelgid (Adelges tsugae Annand) from four populations in Canada. Cold temperatures can play a significant role in the range and impact of pest insects. Severe cold events can reduce the size of insect outbreaks or in some cases even cause outbreaks to end. Measuring the precise impact of cold events, however, can be difficult because estimates of insect mortality are often made at the end of the winter season. In late January, 2023 long-term climate models predicted a significant cold event to occur over eastern North America. We used this event to evaluate the immediate impact on hemlock woolly adelgid overwintering mortality at four sites on the northern edge of the insects invaded range in eastern North America. We observed complete mortality, partial mortality and no effect of the cold event that correlated with the location and strength of the cold event. Our data also showed lack of support for preconditioning of overwintering adelgids as impacting their overwintering survival following this severe cold event. Finally, we compared the climatic conditions at our sites to historical weather data. The cold event observed in February 2023 resulted in the coldest temperatures observed at these sites, including the period within which hemlock woolly adelgid invaded these sites, suggesting cold conditions, especially under anthropogenic climate forcing, may not be a limiting factor in determining the ultimate northern range of hemlock woolly adelgid in eastern North America. Methods Insects were collected from infested trees at 4 sites in 2 Canadian provinces immediately before and immeditely after a severe cold spell. The health and status of the insects (live/dead) was determined in a laboratory. The survival was then compared to observed temperature data extracted from Environment and Climate Change Canada weather stations.

From the mid-1970s through the mid-1990s, air samples were collected for the purposes of monitoring atmospheric CO2 from four sites in the AES air sampling network. Air samples were collected approximately once per week, between 12:00 and 16:00 local time, in a pair of evacuated 2-L thick-wall borosilicate glass flasks. Samples were collected under preferred conditions of wind speed and direction (i.e., upwind of the main station and when winds are strong and steady). The flasks were evacuated to pressures of ~1 — 10-4 mbar or 0.01 Pa prior to being sent to the stations. The airwas not dried during sample collection. The flask data from Alert show an increase in the annual atmospheric CO2 concentration from 341.35 parts per million by volume (ppmv) in 1981 to 357.21 ppmv in 1991. For Cape St. James, Trivett and Higuchi (1989) reported that the mean annual rate of increase, obtained from the slope of a least-squares regression line through the annual averages, was 1.43 ppmv per year. In August 1992, the weather station at Cape St. James was automated; as a result, the flask sampling program was discontinued at this site. Estevan Point, on the West Coast of Vancouver Island, was chosen as a replacement station. Sampling at Estevan Point started in 1992; thus, the monthly and annual CO2record from Estevan Point is too short to show any long-term trends. The sampling site at Sable Island, off the coast of Nova Scotia, was established in 1975. The flask data from Sable Island show an increase in the annual atmospheric CO2 concentration from 334.49 parts per million by volume (ppmv) in 1977 (the first full year of data) to 356.02 ppmv in 1990. For Sable Island, Trivett and Higuchi (1989) reported that the mean annual rate of increase, obtained from the slope of a least-squares regression line through the annual averages, was 1.48 ppmv per year.
