Q fever is a bacterial infection affecting mainly the lungs, liver, and heart. It is found around the world and is caused by the bacteria Coxiella burnetii. The bacteria affects sheep, goats, cattle, dogs, cats, birds, rodents, and ticks. Infected animals shed this bacteria in birth products, feces, milk, and urine. Humans usually get Q fever by breathing in contaminated droplets released by in...

BACKGROUND Fisheries exploitation, habitat destruction, and climate are important drivers of variability in recruitment success. Understanding variability in recruitment can reveal mechanisms behind widespread decline in the abundance of key species in marine and terrestrial ecosystems. For fish populations, the match-mismatch theory hypothesizes that successful recruitment is a function of the...

Psychrophilic methanogenic Archaea contribute significantly to global methane emissions, but archaeal cold adaptation mechanisms remain poorly understood. Hinted by that mRNA architecture determined secondary structure respond to cold more promptly than proteins, differential RNA-seq was used in this work to examine the genome-wide transcription start sites (TSSs) of the psychrophilic methanoge...

Seasonal non-structural carbohydrate (NSC) dynamics in different organs can indicate the strategies trees use to cope with water stress; however, these remain poorly understood along a large precipitation gradient. In this study, we hypothesized that correlation between availability and NSC concentrations might be strengthened by decreasing Pinus tabulaeformis Carr. forests temperate China. Our...

covariance (EC) measurement tower on the North Slope of Alaska. Donatella Zona et al. measured methane emissions from five EC towers in Alaska throughout the period from June 2013 to January 2015. The authors found that approximately half of total methane emissions occurred during the cold season from September to May, with a substantial portion of these emissions occurring when soil temperatur...

Summary Recreational activities may have negative effects on wildlife, but there are very few studies specifically the of free-flight (i.e., hang-gliders, paragliders and their powered derivatives) wildlife. We review existing scientific this issue in order to identify gaps knowledge at taxonomic-group level develop guidelines minimize impacts recreational found that mainly concerned four ungul...

Predation, the most important source of nest mortality in altricial birds, has been a subject of numerous studies during past decades. However, the temporal dynamics between changing predation pressures and parental responses remain poorly understood. We analysed characteristics of 524 nests of European reed warblers monitored during six consecutive breeding seasons in the same area, and found ...

[1] Metabolism and phenology of Amazon rainforests significantly influence global dynamics of climate, carbon and water, but remain poorly understood. We analyzed Amazon vegetation phenology at multiple scales with Moderate Resolution Imaging Spectroradiometer (MODIS) satellite measurements from 2000 to 2005. MODIS Enhanced Vegetation Index (EVI, an index of canopy photosynthetic capacity) incr...
