An introduced population of Black-tailed Prairie Dogs, Cynomys ludovicianus, has persisted for the past 50 years east of Edmonton, Alberta, over 600 km northwest of the natural prairie range of the species. This colony has slowly expanded at this northern latitude within a transition ecotone between the Boreal Plains ecozone and the Prairies ecozone. Although this colony is derived from escaped animals, it is worth documenting, as it represents a significant disjunct range extension for the species and it is separated from the sylvatic plague (Yersina pestis) that threatens southern populations. The unique northern location of these Black-tailed Prairie Dogs makes them valuable for the study of adaptability and geographic variation, with implications for climate change impacts on the species, which is threatened in Canada.

Dew Formation

In this study, we performed model simulations to investigate the spatial, seasonal, and annual dew yield during 40 years (1979–2018) at ten locations reflecting the variation of climate and environmental conditions in Jordan. In accordance with the climate zones in Jordan, the dew formation had distinguished characteristics features with respect to the yield, seasonal variation, and spatial variation. The highest water dew yield (an overall annual mean cumulative dew yield as high as 88 mm) was obtained for the Mountains Heights Plateau, which has a Mediterranean climate. The least dew yield (as low as 19 mm) was obtained in Badia, which has an arid climate. The dew yield had a decreasing trend in the past 40 years due to climate change impacts such as increased desertification and the potential of sand and dust storms in the region. In addition, increased anthropogenic air pollution slows down the conversion of vapor to liquid phase change, which also impacts the potential of dew formation. The dew yield showed three distinguished seasonal patterns reflecting the three climates in Jordan. The Mountains Heights Plateau (Mediterranean climate) has the highest potential for dew harvesting (especially during the summer) than Badia (semi-arid climate).

Annual Reduction

Uncertainty remains regarding the role of anthropogenic climate change in declining insect populations, partly because our understanding of biotic response to climate is often complicated by habitat loss and degradation among other compounding stressors. We addressed this challenge by integrating expert and community scientist datasets that include decades of monitoring across more than 70 locations spanning the western United States. We found a 1.6% annual reduction in the number of individual butterflies observed over the past four decades, associated in particular with warming during fall months. The pervasive declines that we report advance our understanding of climate change impacts and suggest that a new approach is needed for butterfly conservation in the region, focused on suites of species with shared habitat or host associations.

The change in Global climate is due to increasing concentration of greenhouse gases (GHG) in the atmosphere. The earths’ observed climatic changes over the past 50 years are primarily caused by various human activities. The increasing global temperature over the past century by about 0.8°C and expected to rise between 0.9 and 3.5°C by 2100. Such changes will not only have a great effect on the growth and cultivation of different crops but also affect the reproduction, spread and severity of many plant pathogens. Various plant disease models have been developed to incorporate more sophisticated climate predictions at various levels. At the level, the adaptive potential of plant and pathogen populations may prove to be one of the most important predictors of the magnitude of climate change effects. This review highlights various influences of climate change on plant diseases and their effects with suitable examples.SAARC J. Agri., 14(2): 200-209 (2016)

Source Of Information

Abstract Silvics of North America (SNA) is a widely used silvicultural manual. However, the last SNA was published in 1990. Therefore, 2,589 registered foresters were surveyed across four US states to answer two broad questions: (1) Should SNA be updated? And (2) would an updated SNA still be a useful tool for forest management? Most respondents indicated that the type and extent of content contained in the previous version of SNA was still desirable today. Aside from updating all sections with recent research findings, expansion was suggested for ecosystem services provided by species. An update to maps provided in SNA, through changes to natural ranges of tree species and other aesthetic improvement, was suggested by most survey respondents. These findings support the conclusion that the SNA would still be an essential source of information if 21st-century issues such as climate change impacts and adaptation measures were included in the update. Study Implications: There have been major changes in the environment and forest science over the past 30 years, but SNA has not been revised to reflect these changes. The results of this survey indicate that an update to SNA is warranted. The results presented here can serve as a guide for a future update of SNA.

Change Impact

For the past few decades, researchers all over the world have agreed that the service life of civil infrastructure is significantly affected by climate change. Pavement is one of these significant infrastructures that can be easily affected by climate change. However, it is well known that predicting climate change is highly complex and dynamic. Hence, a review has been done on available climate change models and the uncertainties involved in climate change prediction. This review addresses various important questions such as (1) What is climate change? (2) How to use climate change models? (3) Uncertainties involved in using climate change models. (4) How does climate change impacts the pavement infrastructure? (5) What are the adaptation and mitigation strategies available? and (6) How do economic costs and emissions change due to climate change? This review is useful to understand climate change and its implications on pavement infrastructure.

Natural Prairie

The blacktail prarie dog (Cynomys ludovicianus) has evolved as a highly successful colonial herbivore with a definite role among natural prairie ecosystems (Coppock et al., 1980; McHugh, 1958). Their coloniality often creates high population densities and heavy use of vegetation (Klatt, 1971; Koford, 1958), inviting conflict with human land use. Exercising management extremes (i.e., completely exterminating prairie dog colonies or allowing the propagation of hugh populations) appears to present little difficulty. The necessary alternative of containing colonial areas and controlling population densities, however, will require nothing short of a complete understanding of prairie dog emigration ecology. Three basic types of prairie dog movement are possible: movements within towns, peripheral expansion of established towns, and long distance dispersals. The latter two categories are of most practical interest, though the amount of within group recruitment must surely exert some influence upon town expansion and dispersal. The subject has received little or no attention in the literature. Expansion of town perimeters and long distance dispersals appear as quite different phenomena. Observations on Badlands N.P. dog towns suggest that estabishment of peripheral burrows rarely occurs over 50 meters from an existing burrow system. Long distance dispersals appear, however, as less common, less successful events which bring individuals into other populations or initiate new colonies. Blacktail prairie dogs have been located over four miles from existing towns (Smith, 1958). Expansion along town peripheries has been described as both an early springtime activity (King, 1955; Koford, 1958; Smith, 1958) and an autumnal activity (Costello, 1970). Little agreement, and less data, exists upon the structure of these emigrating individuals; and only speculation is responsible for our present notions about the variables which control this movement.
