Ecoregional differences contribute to genetic environmental interactions and impact animal performance. These differences may become more important under climate change scenarios. Utilizing genetic diversity within a species to address such problems has not been fully explored. In this study Hereford cattle were genotyped with 50K Bead Chip or 770K Bovine Bead Chip to test the existence of gene...

line n-78-14 with the pedigree of sha4/chil cm91099-25y-om-3n-1y-oyz-o10m-oy-3m-o10 was obtained from cimmyt, mexico in 1996 through high rainfall wheat screening nursery. preliminary evaluation of the genotypes in international nursery in gorgan and sari research stations during 1996-97 cropping season, resulted in selection of this line as one of the most high yielding genotypes. selected lin...

Vegetation change, whether it be of anthropogenic or climatic origin, can have dramatic effects on landscape form, processes and sediment yield. General conceptual models for relationships between climate, vegetation and sediment yield exist for whole landscapes, but no rigorous analysis of the effects of vegetation change on sediment transport, in the absence of overland flow, has been done fr...

—Approximately one-fifth (ten species) of the plant megafossils in the Chinle Formation in Petrified Forest National Park, Arizona are the remains of ferns or fern-like leaves. Four of the species are assigned to living families, two are assigned to extinct families and the others are unassigned. The nearest living relatives and morphological features of these plants indicates that they lived u...

UNLABELLED Cricketers are often required to play in hot/humid environments with little time for heat adaptation. PURPOSE We examined the effect of a short 4-d hot/humid acclimation program on classical physiological indicators of heat acclimation. METHODS Male club cricketers were randomly assigned into heat acclimation (ACC, n = 6) or control (CON, n = 6) groups, and 30 min treadmill trial...

We describe volumetric changes in three benchmark glaciers in the Nepal Himalayas on which observations have been made since the 1970s. Compared with the global mean of glacier mass balance, the Himalayan glaciers showed rapid wastage in the 1970s-1990s, but similar wastage in the last decade. In the last decade, a glacier in an arid climate showed negative but suppressed mass balance compared ...

Energy crisis, global warming and other environmental issues are what motivate researchers to find new strategies to reduce energy consumption in buildings. Recently, using phase change materials (PCM) in the building’s envelopes has drawn significant attention as an energy-saving method, which helps in increasing the building’s thermal capacity. In the present research, the effects of the main...

The quantity of leachate is crucial when assessing pollution emanating from municipal landfills. In most cases, existing leachate quantification measures only take into account one source - precipitation, which resulted in serious underestimation in China due to its waste properties: high moisture contents. To overcome this problem, a new estimation method was established considering two source...

[1] The relative impact of a large upstream dam versus in‐reach groundwater pumping on stream temperatures was analyzed for humid, semiarid, and arid conditions with long dry seasons to represent typical climate regions where large dams are present, such as the western United States or eastern Australia. Stream temperatures were simulated using the CE‐QUAL‐W2water quality model over a 110 kmmod...
