\begin{abstract}
How snow phenology (SP) regulates ecosystem productivity (EP),
especially for those lower- and higher-EP ecosystems, is a point of
interest for understanding of climate-biosphere interactions but has
been an open macroecological question. We were further curious about its
premise -- must this eco-effect be caused by the SP in the same site
exclusively? To handle these puzzles, we creatively proposed a new
concept of ``periconnection'', following the way of defining
``teleconnection'' but also expandingly probing the possible connections
to neighborhoods, for reflecting the ecological links between EP and the
SP of the same and neighboring sites. Analyzing two piled-up datasets of
vegetation dynamics (1999--2013) and SP (2001--2014) in the Northern
Hemisphere (\textgreater{}45\selectlanguage{ngerman}°N), we found that the lower- and higher-EP
ecosystems showed weaker tendencies of EP increasing than the average
one for all of the ecosystems; the Arctic circumpolar EP was more
sensitive to the snow-onset than -end SP; the EP variations of the
ecosystems, including those of the lower- and higher-EP ones, were
driven more by the SP around -- termed as neighborhood eco-effect;
further, such drivings occurred more to north in North America while
more to south in North Eurasia -- as directional eco-effect. Overall,
the novel ``periconnection'' concept is of fundamental implications for
advancing the progress of many fields ranging from ecology to Earth
interactions.%
