Web19 mrt. 2024 · In the early 1990s, the latitudinal herbivory hypothesis (LHH) was proposed to explain why the herbivory and plant defense is greater in lower latitudinal areas than in higher latitudinal areas, which is the primary reason for the maintenance of a higher biodiversity in the tropics (Coley & Aide, 1991; Coley & Barone, 1996; Schemske … Web1996; Schemske et al. 2009). For plant–herbivore interactions, the Latitudinal Herbivory-defense Hypothesis (hereafter LHDH, Coley and Aide 1991) predicts that increasing herbivore pressure at lower latitudes should select for greater investment in plant defenses (Pennings et al. 2001, 2009; Rasmann and Agrawal2011).Indeed ...
