Changes in the distribution of mechanically dependent plants along a gradient of past hurricane impact.

Batke SP, Kelly DL - AoB Plants (2015)

Bottom Line: The severity of the effects that large disturbance events such as hurricanes can have on the forest canopy and the associated mechanically dependent plant community (epiphytes, climbers, etc.) is dependent on the frequency and intensity of the disturbance events.For holo- and hemi-epiphytes, we found that diversity was significantly negatively related to past hurricane impact.We believe that more emphasis needs to be placed on the effects that past disturbance events have on mechanically dependent plant communities, particularly in areas that are prone to catastrophic perturbations.

PLV096F2: The four mechanically dependent families with the highest species richness and abundance of individuals in Cusuco National Park.

Mentions: A total of 7074 individuals of mechanically dependent species from 60 host trees were identified. The majority of dependent plants censused (71.5 %) were infertile (having neither flowers nor fruit). Individuals (98.9 %) were identified to family, 95.1 % to genus and 69.8 % to species level. An additional 10.9 % of individuals apparently matched a particular species but were not confirmed as the same (and are distinguished as ‘cf.’). From the 7074 individuals, a total of 214 species from 90 different genera and 43 different families were identified [see Batke et al. (2015) for a full account of the species]. The four families with the highest species richness and abundance were Orchidaceae, Polypodiaceae, Bromeliaceae and Araceae (Fig. 2). The life-form group with the highest species richness and abundance was holo-epiphytes, followed by climbers, nomadic vines, primary hemi-epiphytes, mistletoes and accidental epiphytes (Table 1). Although stranglers were observed in CNP [Ficus (Moraceae), three species], none were found on the sampled trees.Table 1.
