Diversity of culturable endophytic fungi vary through time in Manihot esculenta Crantz

Brazilian Journal of Biology, 2022
Endophytic fungi are a ubiquituos group that colonize all plant species on earth. Studies comparing the location of endophytic fungi within the leaves and the sampling time in Manihot esculenta Crantz (cassava) are limited.

Investigating the role of task relevance during rhythmic sampling of spatial locations

Scientific Reports, 2023
Recently it has been discovered that visuospatial attention operates rhythmically, rather than being stably employed over time. A low-frequency 7–8 Hz rhythmic mechanism coordinates periodic windows to sample relevant locations and to shift towards other,

Island characteristics and sampling methodologies influence the use of stable isotopes as an ecosystem function assessment tool

Ecological Solutions and Evidence, 2021
Monitoring seabird‐derived nutrients on islands following invasive mammal eradications may provide a useful, cost‐ and time‐efficient indication of the recovery of ecosystem function; however, the technique has only been investigated on environmentally ...

A comparison of temporal and location-based sampling strategies for global positioning system-triggered electronic diaries

Geospatial Health, 2016
Self-reporting is a well-established approach within the medical and psychological sciences. In order to avoid recall bias, i.e. past events being remembered inaccurately, the reports can be filled out on a smartphone in real-time and in the natural ...
