Both real-time and long-term environmental data perform well in predicting shorebird distributions in managed habitat
<p>Highly mobile species, such as migratory birds, respond to seasonal and inter-annual variability in resource availability by moving to better habitats. Despite the recognized importance of resource thresholds, species distribution models typically rely on long-term average habitat conditions, mostly because large-extent, temporally-resolved, environmental data are difficult to obtain. Recent advances in remote sensing make it possible to incorporate more frequent measurements of changing landscapes; however, there is often a cost in terms of model building and processing and the added value of such efforts is unknown. Our study tests whether incorporating real-time environmental data increases the predictive ability of distribution models, relative to using long-term average data. We developed and compared distribution models for shorebirds in California's Central Valley based on high temporal resolution (every 16-days), and 17-year long-term average, surface water data. Using abundance-weighted boosted regression trees, we modeled monthly shorebird occurrence as a function of surface water availability, crop type, wetland type, road density, temperature, and bird data source. While modeling with both real-time and long-term average data provided good fit to withheld validation data (0.79 < AUC < 0.89 across taxa), there were small differences in model performance. The best models incorporated long-term average conditions and spatial pattern information for real-time flooding (e.g. perimeter-area ratio of real-time water bodies). There was not a substantial difference in the performance of real-time and long-term average data models within time periods when real-time surface water differed substantially from the long-term average (specifically during drought years 2013-2016) and in intermittently flooded months or locations. Spatial predictions resulting from the models differed most in the southern region of the study area where there is lower water availability, fewer birds, and lower sampling density. Prediction uncertainty in the southern region of the study area highlights the need for increased sampling in this area. Because both sets of data performed similarly, the choice of which data to use may depend on the management context. Real-time data may ultimately be best for guiding dynamic, adaptive conservation actions whereas models based on long-term averages may be more helpful for guiding permanent wetland protection and restoration. --</p>

FIGURE 20 in Amphibians and reptiles in North Sweden: distribution, habitat affinities, and abundance (Classes: Amphibia and Reptilia)
FIGURE 20. Talus slopes and screes provide communal hibernation sites for Vipera berus, offering frost-free conditions also in case of early winter weather with little insulating snow cover. Such sites invariably face SW–SE and have early snowmelt that permits earlier spring emergence than in surrounding areas. Mating usually takes place here, after which vipers disperse to summer habitats visible in the background. This picture is from one of the northernmost known hibernation sites in Sweden at 68oN.

FIGURE 18. Summer habitat for Rana temporaria and Rana arvalis in boreal riparian deciduous woodland. The canopy is dominated by Alnus incana, Prunus padus, and Sorbus aucuparia, with scattered Salix caprea and Betula pubescens. The lush herbaceous field layer provides shelter and abundant invertebrate food in summer. Population density at this site has been estimated at up to 7500 and 6000 adults/km2 of Rana temporaria and R. arvalis, respectively. Bölesholmarna, Umeå, Västerbotten, Middle Boreal region.

FIGURE 16. Rana temporaria is the hardiest amphibian in North Sweden, ranging up to the transition between the Mid- and High-Alpine life zones. Individuals in these uppermost populations often give a toad-like impression due to their dark color and short hindlimbs. Stekenjokk, Jämtland, 1070 m altitude. Photo: Johan Elmberg.

FIGURE 12. Ongoing post-glacial land uplift creates open habitats along the Baltic coast of North Sweden. Rock pools (foreground) serve as breeding sites for Rana temporaria and Bufo bufo, occasionally also for Lissotriton vulgaris. Brushy areas along the forest edge (background) are typical summer habitat for Zootoca vivipara and Vipera berus. Tjäruskär, Ångermanland, Middle Boreal region. Photo: Johan Elmberg.
FIGURE 17 in Amphibians and reptiles in North Sweden: distribution, habitat affinities, and abundance (Classes: Amphibia and Reptilia)
FIGURE 17. Rana temporaria is the only amphibian breeding in alpine heath habitats well above tree line in the Scandic Mountains of North Sweden. Among the variety of wetland types available, chorusing and spawning invariably take place in shallow ponds with moderate to sparse vegetation. Despite high altitude and latitude, a short annual activity period, and a cool overall climate, breeding ponds enjoy constant daylight, high insolation and thus warm up rapidly.

FIGURE 14 in Amphibians and reptiles in North Sweden: distribution, habitat affinities, and abundance (Classes: Amphibia and Reptilia)
FIGURE 14. Vast areas of North Sweden's interior are covered by level open bogs with permanent water. Rana temporaria, R. arvalis, and Bufo bufo breed in the pool depressions (foreground) and come ashore to forage in grassy areas in summer. More elevated and drier string parts of the bogs offer protective vegetation and summer habitat för Zootoca vivipara and Vipera berus. Photo: Jonas Grahn.

FIGURE 15. Summer habitat for Rana temporaria in the transition between the Mid- and High-Alpine life zones. Here the annual activity period lasts three months or less, during which adults adopt a semi-aquatic lifestyle, spending much time in small creeks and seepage areas.

FIGURE 10. Distribution of Vipera berus in North Sweden. Colored parts of the Baltic in Ångermanland, Västerbotten, and Norrbotten represent areas with widespread occurrence on offshore islands. Triangles at sea in Medelpad and Hälsingland represent more singular offshore occurrences. Question marks denote areas where the western range limit is poorly known.

FIGURE 8. Distribution of Anguis fragilis in North Sweden. The oval in northernmost Västerbotten represents many records over a long time period, a population that is possibly disjunct. Note the total lack of records from offshore islands in the Baltic.

FIGURE 9. Distribution of Natrix natrix in North Sweden. The green circle denotes a disjunct record in Härjedalen, for which there is no suspicion of anthropogenic origin. Triangles show occurrence on far offshore islands in the Baltic. Filled black circles denote well-documented records where anthropogenic origin can be suspected (cf. Elmberg 1995). None of the latter represent permanent reproducing populations. A question mark shows area where presence is likely but has not been documented.
FIGURE 4 in Amphibians and reptiles in North Sweden: distribution, habitat affinities, and abundance (Classes: Amphibia and Reptilia)
FIGURE 4. Distribution of Bufo bufo in North Sweden. Colored areas of the Baltic are those with widespread occurrence on offshore islands. The extremely isolated offshore occurrence on the islet Bonden is shown by a triangle. Possibly disjunct occurrences in northern Norrbotten and close to the Alpine region in Jämtland are shown by a filled circle. Question marks show areas where presence is possible but has not been documented.
