Reducing representativeness and sampling errors in radio occultation–radiosonde comparisons [PDF]
Atmospheric Measurement Techniques, 2018 Radio occultation (RO) and radiosonde (RS) comparisons provide a means of analyzing errors associated with both observational systems. Since RO and RS observations are not taken at the exact same time or location, temporal and spatial sampling errors ...

Heterogeneity of Microbial Communities in Soils From the Antarctic Peninsula Region
Frontiers in Microbiology, 2021 Ice-free areas represent less than 1% of the Antarctic surface. However, climate change models predict a significant increase in temperatures in the coming decades, triggering a relevant reduction of the ice-covered surface.

Gut microbiota of migrating wild rabbit fish (Siganus guttatus) larvae have low spatial and temporal variability [PDF]
, 2019 We investigated the gut microbiota of rabbit fish larvae at three locations in Vietnam (ThuanAn-northern, QuangNam-intermediate, BinhDinh-southern sampling site) over a three-year period. In the wild, the first food for rabbit fish larvae remains unknown,

P1-S4.08 Population size estimates for men who have sex with men in Guatemala City using time location sampling and respondent driven sampling [PDF]
Sexually Transmitted Infections, 2011 BackgroundMen who have sex with men (MSM) are highly vulnerable to HIV infection, but this population can be particularly difficult to reach in Central America due to stigma and violence. Knowing the size of populations at high risk for HIV and sexually transmitted infections (STI) is critical for informing prevention, care, and treatment programs ...
