资源简介:
This dataset contains daily data extracted from phenocams installed
at a global exchange experiment involving Chihuahuan desert plant
communities at the Jornada Basin LTER site in southern New Mexico,
U.S.A. Cycles of plant growth, termed phenology, are tightly linked
to environmental controls, and our overarching objective in this
study is to determine if temperature or precipitation are relatively
more important for determining shrub and grass greenup date (start
of season) and senescence date (end of season). At these camera
locations, we experimentally manipulated incoming precipitation at
the Jornada Basin LTER for over a decade and recorded plant leaf
phenology at the daily scale for seven years using phenocams. The
data included here comes from phenocams installed in two ongoing
studies at the Jornada Basin LTER site, one studying ecosystem
responses to long term changes in water and nitrogen availability,
and one studying plant productivity and partitioning responses to
water availability and herbivory (studies 349 and 456,
respectively). Phenocams at the sites have collected images since
2014, and this dataset includes color values extracted from shrub
and grass regions in these images. Further analyses, including daily
values of calculated greenness (green chromatic coordinate),
precipitation, and temperature, for all the plots included in the
study are in EDI dataset knb-lter-jrn.210574002. This study is
ongoing.
