WebFor a simple two-box model, with the tropics and extratropics denoted as subscripts, diversity in the tropics ( DT) is determined by OT – ET + IT, and diversity in the extratropics ( DE) by OE – EE + IE ( Fig. 1 ). With this notation, it can easily be seen that a latitudinal gradient in richness, with DT > DE, can result from many different ... WebIn particular, recent meta-analysis questioned the hypothesis that herbivory increases from the poles towards the equator.

Web1 okt. 2016 · The Latitudinal Herbivory-Defense Hypothesis Researchers long have argued that biotic interactions are stronger at equatorial latitudes (see Glossary ), such that biotic selective agents drive adaptation in tropical organisms, while abiotic selection pressures more strongly influence temperate organisms 1, 2, 3. WebTheory suggests that coexistence is enhanced among competing insects breeding in discrete and ephemeral resources, if the larvae are aggregated over the breeding sites.
