A new preparation method for testate amoebae in minerogenic sediments by X. Zheng, J.B. Harper, G. Hope, S.D. Mooney

“…Although the majority of research has been conducted on ombrotrophic peatlands in the Northern Hemisphere, the application of testate amoebae in minerogenic sediments, such as minerotrophic peatlands and saltmarshes, holds considerable promise but is often impeded by the low concentration of testate amoebae and by time-consuming counting. …”

Future Seasonal Changes in Extreme Precipitation Scale With Changes in the Mean by Margot Bador, Lisa V. Alexander

“…Over land, we find a strong intensification of the wettest day in all seasons over the mid and high latitudes of the Northern Hemisphere and over India during the monsoon. Extreme intensity decreases in the subtropics for some seasons, including over large regions around the Mediterranean basin and Southern Africa, and these drying patterns are not apparent in annual results. …”

Elevational diversity pattern and allochronic divergence of scorpionflies in the Qinling Mountains by Peng-Yang Wang, Bao-Zhen Hua

“…Scorpionflies (Mecoptera, Panorpidae) as a relict group of holometabolous insects normally inhabit dense vegetations of mountain regions in the northern hemisphere. They are vulnerable to temperature changes and deforestation and thus play a significant role in insect conservation as ecological indicators. …”

Summertime atmosphere–ocean preconditionings for the Bering Sea ice retreat and the following severe winters in North America by Takuya Nakanowatari, Jun Inoue, Kazutoshi Sato, Takashi Kikuchi

“…We found that the 3-month leading (August–September) geopotential height at 500 hPa (Z500) in the Northern Hemisphere explains 29% of SIA variability. The spatial pattern of Z500 for positive (negative) sea ice anomalies is associated with negative (positive) anomalies over the Gulf of Alaska related to the Pacific transition (PT) pattern. …”

The complete chloroplast genome of Fagus crenata (subgenus Fagus) and comparison with F. engleriana (subgenus Engleriana) by James R. P. Worth, Luxian Liu, Fu-Jin Wei, Nobuhiro Tomaru

“…These highly variable chloroplast regions in addition to 160 chloroplast microsatellites identified (of which 46 were variable between the two species) will provide useful genetic resources for studies of the inter- and intra-specific genetic structure and diversity of this important northern hemisphere tree genus.…”

Results of PMIP2 coupled simulations of the Mid-Holocene and Last Glacial Maximum &ndash; Part 2: feedbacks with emphasis on the location of the ITCZ and mid- and high latitudes he... by Y. Zhao, Y.

Joussaume, S. Harrison, B. Otto-Bliesner, P. Braconnot

“…Finally, we show that the feedback from snow and sea-ice at mid and high latitudes contributes for half of the cooling in the Northern Hemisphere for the LGM, with the remaining being achieved by the reduced CO₂ and water vapour in the atmosphere. …”

Insights into the Time Evolution of Slowly Photodegrading Contaminants by Davide Vione

“…Apart from poorly predictable weather-related issues, fair-weather irradiance has a seasonal trend that results in the fastest photodegradation in June and the slowest in December (at least in temperate areas of the northern hemisphere). Pollutants that have first-order photochemical lifetimes longer than a week take more than one month to achieve 95% photodegradation. …”

Stable isotopic evidence of El Niño-like atmospheric circulation in the Pliocene western United States by M. J. Winnick, J. M. Welker, C. P. Chamberlain

“…We propose that the westerly storm track migrated northward through the late Pliocene with the development of the modern cold tongue in the east equatorial Pacific, then returned southward with widespread glaciation in the Northern Hemisphere – a scenario supported by terrestrial climate proxies across the US. …”
