Ecophysiological and ultrastructural characterisation of the circumpolar orange snow alga Sanguina aurantia compared to the cosmopolitan red snow alga Sanguina nivaloides (Chlorophyta) [0.03%]
环极地橙色雪藻Sanguina aurantia的生态生理和超微结构特征与泛域红色雪藻Sanguina nivaloides(绿藻门)的比较研究
Lenka Procházková,Daniel Remias,Andreas Holzinger et al.
Lenka Procházková et al.
Red snow caused by spherical cysts can be found worldwide, while an orange snow phenomenon caused by spherical cells is restricted to (Sub-)Arctic climates. Both bloom types, occurring in the same localities at Svalbard, were compared ecoph...
The importance of Calanus glacialis for the feeding success of young polar cod: a circumpolar synthesis [0.03%]
北冰洋贻贝对幼年极地鳕鱼喂养成功的意义:一项全球综合研究
Caroline Bouchard,Louis Fortier
Caroline Bouchard
Understanding the feeding ecology of polar cod (Boreogadus saida) during its first year of life is crucial to forecasting its response to the ongoing borealization of Arctic seas. We investigated the relationships between diet composition a...
Freeze-thaw cycles have minimal effect on the mineralisation of low molecular weight, dissolved organic carbon in Arctic soils [0.03%]
冻融循环对北极土壤中低分子量溶解有机碳的矿化作用影响较小
A Foster,D L Jones,E J Cooper et al.
A Foster et al.
Warmer winters in Arctic regions may melt insulating snow cover and subject soils to more freeze-thaw cycles. The effect of freeze-thaw cycles on the microbial use of low molecular weight, dissolved organic carbon (LMW-DOC) is poorly unders...
Diatom communities in the High Arctic aquatic habitats of northern Spitsbergen (Svalbard) [0.03%]
北极斯匹茨卑尔根北部高地水域的藻类群落
Aleksandra Zgrundo,Barbara Wojtasik,Peter Convey et al.
Aleksandra Zgrundo et al.
As High Arctic environments are particularly sensitive to global and regional climate changes, a growing number of studies have focused on that region. It has been shown that living and fossil diatoms can be successfully used to track envir...
Health of Antarctic birds: a review of their parasites, pathogens and diseases [0.03%]
南极鸟类的健康状况:其寄生虫、病原体和疾病的综述
Andrés Barbosa,María José Palacios
Andrés Barbosa
Antarctic birds are not beyond the effects of parasites or pathogens. However, potential ecological consequences of wide-spread infections for bird populations in Antarctica have received little attention. In this paper, we review the infor...
Molecular surveillance for avian influenza A virus in king penguins (Aptenodytes patagonicus) [0.03%]
用于帝企鹅(Aptenodytes patagonicus)的禽流感病毒分子监测
Chung-Ming Chang,Camille Lebarbenchon,Michel Gauthier-Clerc et al.
Chung-Ming Chang et al.
An investigation of the presence of influenza A virus has been conducted in king penguins (Aptenodytes patagonicus) at the Possession Island in the Crozet Archipelago, Antarctica, using a rapid molecular diagnostic method based on real-time...
Nutrient availability limits biological production in Arctic sea ice melt ponds [0.03%]
营养限制制约着北极融池生物生产力
Heidi Louise Sørensen,Bo Thamdrup,Erik Jeppesen et al.
Heidi Louise Sørensen et al.
Every spring and summer melt ponds form at the surface of polar sea ice and become habitats where biological production may take place. Previous studies report a large variability in the productivity, but the causes are unknown. We investig...
Diversity and abundance of microbial eukaryotes in stream sediments from Svalbard [0.03%]
斯瓦尔巴群岛河流沉积物中微生物真核生物的多样性和丰富度
R S Hindshaw,M R Lindsay,E S Boyd
R S Hindshaw
Microbial eukaryotes are increasingly being recognised for their role in global biogeochemical cycles, yet very few studies have focussed on their distribution in high-latitude stream sediments, an important habitat which influences stream ...
The potential role of Antarctic krill faecal pellets in efficient carbon export at the marginal ice zone of the South Orkney Islands in spring [0.03%]
南极虾春季在南奥克尼群岛边缘冰区高效碳汇运输中的潜在作用
A Belcher,G A Tarling,C Manno et al.
A Belcher et al.
Antarctic krill (Euphausia superba) play a central role in the food web of the Southern Ocean, forming a link between primary production and large predators. Krill produce large, faecal pellets (FP) which can form a large component of mesop...
Resistance of Arctic phytoplankton to ocean acidification and enhanced irradiance [0.03%]
北极浮游植物抵抗海洋酸化和增强辐射性能力
C J M Hoppe,N Schuback,D Semeniuk et al.
C J M Hoppe et al.
The Arctic Ocean is a region particularly prone to ongoing ocean acidification (OA) and climate-driven changes. The influence of these changes on Arctic phytoplankton assemblages, however, remains poorly understood. In order to understand h...
