Re: Oops, a momenti mi dimentico.
Certo che siete forti:
Loggers were wrapped in parafilm and enclosed
in small plastic containers with CaSO4 as desiccant.
Each container had a » 1 cm diameter hole in the side
wall through which an external temperature probe
extended from the logger into the nest. Once the probe
had been strung through the hole, silicone gel was
used to seal the hole to keep out moisture. Each logger
was placed 1 m from the nest at nest depth and the
external probe was extended underground into the
side of the corresponding turtle nest. Loggers were
programmed to record temperatures every 48 min.
"Three HOBO®-TEMP temperature loggers with
internal temperature sensors were also used in this
study. Two of these were placed in separate zipperseal
bags with desiccant to record ambient air temperature.
One was affixed to the bottom of a bench
(» 40 cm above the ground) within the nesting area to
avoid attracting human attention. The second temperature
logger was placed in a north-facing hollow at the
base of a tree behind a wire mesh screen. Ambient
temperature data were also obtained from the National
Weather Service recording station at Lock & Dam 13,
located 5·5 km south of the field site. The third
HOBO®-TEMP logger was used to measure temperatures
in nest 87 from the intermediate ‘shade’ class
Quindi si tratta della temperatura interna di nidi all'asciutto.
Non inventatevi idiozie!
