“…Unlike TG3 species, many TG4 species died during the closure of the canopy, as observed in March 2008. The production of foliage in the crown, building of large stems with many small secondary axes and a scrambling mode of climbing are traits that make them vulnerable to strong winds (Schnitzler et al 2012). These plants have remained modest in number and size, showing a slow recovery after large scale disturbance.…”

“…Correspondence analysis (CA) of these selected traits revealed four groups (TG1 to TG4), all of which showed differences in terms of abundance and species richness along a gradient of disturbance (Schnitzler et al. ). The method chosen for the preliminary research in 2008 highlighted the importance of light in the forest recovery process and helped to specify the life traits adequate for describing the structural changes in the vegetation.…”

“…A preliminary study was carried out 8 mo after the event, in March 2008. In this study, we identified a few climber traits that express a capacity to re-establish after drastic structural changes (Westoby & Wright 2006;Isnard & Silk 2009;Schnitzler et al 2012) to explain the distribution of vines within the forest. We therefore selected four vegetative life traits (Plant traits can be defined as sets of plants exhibiting similar responses to environmental conditions; Walker 1992) that were thought to be relevant for the maintenance of climbers in forests: climbing mode (tendrils, twining, or adventitious roots as binomial variables), vegetative properties (herbaceous with soft/deciduous leaves or woody stems with tough/evergreen leaves), dimension (diameter and length: quantitative variables) and the three vertical strata where leaves are most densely aggregated (<5, 5-10, >10 m: semi-quantitative variables).…”

International audienceQuestionIn dense tropical forests, climbers and hemiepiphytes depend on the quantity and quality of direct light more than other plant life forms. What are their responses with respect to quantitative changes of canopy structure and light regime after a hurricane? Here, we study their contribution to closure of the canopy and changes in light regime, with the help of hemispherical photography. Their change in space and time may serve as an illustration and measure of key processes after repetitive large disturbances.LocationMartinique, the Plateau Concorde, in an evergreen montane forest.MethodsAfter Hurricane Dean, a diachronic study (2008-2012) was carried out. Four parallel surface areas 50x10m were set up. Canopy structure and light conditions were assessed with hemispherical photographs, using a polar projection fisheye lens. All standing trees >5cm DBH, and all climbers and hemiepiphytes were mapped and identified to species. Correspondence analysis (CA) using selected life traits illustrated the distribution of climbers present on trees per category (a total of four). The number of individuals and species which have disappeared or appeared per category was calculated.ResultsFrom 2009 to 2012, the total number of climbers and hemiepiphytes decreased from 248 to 225, but in different proportions according to strata. Climbers were classified into categories in function of the range of responses (i.e. resistance and responsiveness).ConclusionOur study demonstrates the potential to detect climber/hemiepiphyte strategies after a large disturbance using hemispherical photography and plant traits

Exotic vine invasions following cyclone disturbance in Australian Wet Tropics rainforests: A review

The Australian Wet Tropics region extends for almost 900 000 ha along the coastline of north‐east Queensland. The rainforests in this region have a rich and unique biodiversity and are World Heritage listed by UNESCO. Disturbance from tropical cyclones is a significant driver of the rainforest dynamics in this area, and when frequent or intense can facilitate the recruitment and expansion of exotic invasive species. Exotic vines are of particular concern for forest conservation as they can be highly competitive with native vegetation and may prevent forest regeneration. This literature review found evidence that fragmented forests, which are very common in the Australian Wet Tropics, are vulnerable to post‐cyclone vine invasion. In particular, although the diversity and abundance of herbaceous vines tend to decline as the canopy closes 2 years post‐cyclone disturbance, woody exotic vines and scramblers may persist for much longer or even increase in numbers. Since forest recovery in these systems is influenced by the severity and recurrence of disturbance, an increase in cyclone intensity under climate change may cause rapid changes in rainforest structure, composition and diversity, and increase exotic vine invasion. Post‐cyclone management of vines appears to require direct intervention, with manual cutting being currently the most effective method. However, there are a number of difficulties to its wide implementation in Australia, and further study on options for control is needed.Abstract in Spanish is available with online material.
