Future directions
Despite the fact that the study of HP receipt has a history of at least
40 years (Kanchan & Jayachandra 1980), we are just starting to unravel
the complexity of its delivery (e.g. Fang & Huang 2013, Tur et al.
2016) and its effects (e.g. Muchhala et al. 2010, Arceo-Gómez & Ashman
2011, Arceo-Gómez et al. 2019b). Thus, much remains to be done in order
to fully understand its ecological and evolutionary implications in
natural communities. Here I outline a few avenues of future research
that may help uncover the importance of HP in generating geographic
mosaics of selection and its contribution to shaping patterns of plant
diversity across local and global spatial scales.
